For the Led Light Book, Frequently Asked Questions (FAQ)

1. My Sony TV dropped dead but the LED light( front) keep staying on. What to do?send to repair?PHu?

is the light blinking? if it just died without a surge then I bet the light is blinking 4 times with a long pause then 4 times again. This means the B voltage is low or shorted, this usaully happens when the horizontal output transistor shorts due to bad solder connections on the horizontal drive transformer and/of bad flyback transformer

2. LED lights for my car?

crimson and Blue lights in the front and rear of your motor vehicle are seen unlawful, yet underbodies are seen unlawful as nicely for on highway use. purely fyi the extra effective manufacturers are generally listed in the import tuner mags. yet LED neons are extra effective they final longer and are a sprint extra stable.

------

3. Why has my wireless internet stopped working?

Im assuming which you and your brother are connecting to a similar router..... that ought to knock out the possability of it being the router. It must be your pc config. i could discover out in the adventure that your brothers been fidgeting with the config and enabled or replaced the config for safety on the instant component.

4. Which types of led lights should i use for my subs?

they're unlawful right here in VA, the regulation used to declare it became as quickly as solid adequate interior the vehicle if it became as quickly as under the drivers area window line, in spite of the undeniable fact that they amended it to place off LEDs totally returned approximately 2 or 3 yrs interior the previous

------

5. Do I need a wire connected to the negative terminal for led light bars and if so can I use the negative terminal as ground for the relay

You do need connections between the negative (grounded) terminals of the lights and the negative terminal of the battery.If these lights are on a vehicle, the metal frame and body of the vehicle can serve as the negative/ground connection, as the negative terminal of the vehicle battery will be connected to the vehicle frame

6. Battery Powered LED Light Delay

What id use is a 555 in monostable vibrator mode.Comprehensive information here and obv Google:simple and cheap. Should be pretty reliable and a great starter project for someone new to electronics.

..If you use a pot for the timing resistor, you will be able to adjust the on time :)

------

7. are solar panels sufficient for electric heating?

Are you thinking of installing electric solar panels or thermal solar panels or both? It would be better to install electric solar panels for electric heating. You can run 7 heaters as long as you do the calculations for the number of panels need for the daylight hours, and the required battery bank to supply the required power.

------

8. Using mouse's laser sensor for heartbeat measurement

A mouse generally doesn't provide direct access to the sensor(s).Consider using a PC webcam instead. After all, it is the camera sensor on the phone (with light from the LED) which detects the heart rate.GitHub - thearn/webcam-pulse-detectorA python application that detects and highlights the heart-rate of an individual (using only their own webcam) in real-time.

------

9. What should happen to employers that hire illegal aliens if the illegal turns out to be a minor?

First, it is not the responsibility of employers to enforce our immigrations laws. It is one of the few legitimate activities of our Federal Government. Since it is illegal to hire illegal immigrants the law (questionable though it is) has already been broken. They are probably also liable for infractions of the child labor laws, but that is secondary.

------

10. How can I power LED light strings with a solar panel?

in case you purchase lights that are distinctly image voltaic powered, the potential created by using each unit is probably purely adequate to run the guy strand of lights. even with the shown fact that, you ought to use primary outdoors christmas lights with a small-ish image voltaic panel with inverter to transform the potential for all the lights

------

11. Urgent laptop problem!!! pls help?

Since removing/replacing the battery fixed this, get a can of electrical contact cleaner and spray a little of it on the gold contacts on the battery and where these contacts connect to the computer. While cooling fans have a possiblity of being clogged with dust and hair, it seems this happens when the computer has been off and cool.

------

12. Led light kits for motorcycles?

The LED motorcycle kit is becoming increasingly popular even as more motorbike owners look for new ways of customizing their bikes for both functional and aesthetic appeal purposes. By installing such an LED kit it is possible to totally transform the look of your motorcycle and you are bound to draw lots of stares from admirers

------

13. Ground potential not at zero in 30y old apartment

You should check wiring, if you have three wires in the socket, then it worths to inspect and see what's wrong. Normaly the water pipe is connectected to the same ground, so there should be no voltage diffeence, but is meant to connect water pipe to ground for safety reasons, not to take ground from pipe

------

14. making a led light show out of fuze bottles?

Whether they want to be approached, or left alone is usually the difference between approachable and not approachable. Anybody could be approached in a hypothetical situation, not all situations are hypothetical though. Most people pick up on when somebody wants to be left alone, and when they feel like approaching people, they usually let people know by approaching people.

------

15. Teaching binary encoding - using different symbols

The way I got my kids interested in binary representation was to discuss up to what number they could count on one hand. Learning they could count up to 31 and then understanding why, made the trick. You can then impress them yet again when you show them that with ten fingers then can count to 1023.

------

16. Congress has banned the sale and manufacturer of 75 and 100 watt light bulbs. Why are the products that?

Alright, in reality congressmen don't write bills anymore. Lobbyists for their respective industries write the bills that effect their respective industries which few congressmen have even the time to "read" never-mind understand many of the technological facets or implications of the regulation being signed on. Welcome to the small government, & deregulated world of the plutocrats & monopolists.

------

17. A Question for guys who know LED lights. Can I use ANY LED light for this purpose?

Buy 9 volt batteries for 9 volt items. No longer replace them with different batteries. That is how they're intended to be connected. Any voltage alterations would rationale the batteries to get sizzling and even leak. Ruining the object. Or use a common adapter environment it to the 9 volt . Connecting the wires safely graound to ground and constructive to confident

------

18. Do the colors get staled on LED lights?

Yes, LEDs do age. The structure of the diode junction is fairly precise, and the atoms which form the LED can migrate under the force of the electric field and slowly degrade the functional regions. However, this happens far more slowly than the degradation of incandescent bulbs. (Semiconductor lasers are far more susceptible to this effect. ).

------

19. draw 30W @ 5v to run LED light string and Arduino from a car battery?

In general the LEDs should be stacked 'higher' to take advantage of the higher voltage. So for example, say you can run 4 leds in series with 5V power you can probably run 9 LEDs in series with 12V at the same current. The extra LEDs in series will have added voltage drop to compensate for the higher rail voltage.

------

20. whats better an lcd or plasma?

Plasmas burn something and dont final somewhat as long and could start to have black spots everywhere in the demonstrate screen while the photograph producing element runs out.. LCDs are in basic terms like pc displays so as that they final for an prolonged time.. Plasmas are patently sharper and clearer than LCds. plasmas fee greater too.

21. Led light bulb questions...?

LED bulbs are a good alternative to other lighting options. They last longer and use far less energy than incandescent bulbs. This option provides an energy efficient light turns on hot immediately. Purchasing your LED bulbs from our online store LEDLuxor. LEDLuxor sales team is always there to advise you and help you in your purchase

------

22. Has anyone else read the fine print; Re Green Energy Conscious - Light Bulbs?

Like anything else "environmental" people just drink the Kool-Aid without considering the negatives of the supposedly friendly alternative. Clearcutting forests for corn ethanol is one. Mercury in these light bulbs could be a minor issue considering you may need to change out your rugs, paintings, and sofas after they've faded under fluorescents for a few years.

------

23. Where to buy LED ceiling light to decorate my house?

LEDs can be treated as environment friendly and it have many advantages like lower energy consumption, longer lifetime, improved physical robustness. So your decision of using LED lights is 100% correct. I have found a manufacturer and supplier of LED lights and the lights are high-quality and affordable. Even I shopped so many times from this shop

------

24. Do I need 5V or 12V to power a LED light strip?

Thanks for giving the part number (of the individual LED); I easily Googled it and found out exactly what you're talking about. Indeed, these LEDs work on 5 volts DC, as discussed in all their literature. That probably relates to them being individually addressable. Common, whole-strip-the-same LED strips generally operate on 12V, with a few that operate on 24V

------

25. Cold cathode light or led strip light?

Perhaps the defining feature of LED Strip Lights, their flexibility truly sets them apart. Traditional luminaires were housed inside glass enclosures which were fragile and inflexible. In contrast, with LED Strip Lights, the LEDs are mounted to a flexible "ribbon" of circuit board, which is durable enough to be bent around 90 degree corners and attach to gradiented surfaces.

------

26. Ceiling LED light emits very dim light when switch is off! closed

Some switches have a neon illumination to help find it in the dark; if so it will be connected ACROSS the open switch forming the leakage path mentioned above. No problem as long as the load is much higher than the neon needs, but can cause a CFL or LED to flicker or light dimly

------

27. What is the current market for LED-based modern lamps?

Whereas the market for colored (Red, Green, Blue) RGB LEDs is well established, the market for white LEDs is still growing. Because When you think of industries that still rely on white, non-LED lighting, such as televisions, automotive manufacturers, computer monitors, notebook computers, LCD backlights, etc., you can understand the push to become the leader in white LED manufacturing.

------

28. HELP,I need LED light Help?

pink and Blue lights furniture interior the front and rear of your motor vehicle are seen unlawful, yet underbodies are seen unlawful besides for on highway use. purely fyi the greater constructive manufacturers are many times indexed interior the import tuner mags. yet LED neons are greater constructive they final longer and are somewhat greater sturdy.

------

29. Problems with my laptop power supply?

when you consider which you could use the computer with the charger plugged in it should be your battery. time beyond regulation computer batteries slowly die. An occasion may be whilst i bought a working laptop or computer and after some years the battery would not fee in any respect so i had to purchase a sparkling one.

------

30. Optimal slit width in Young's double slit experiment

I am using a super bright LED torch, and wow!

It even works with pin holes instead of slits, the interference pattern is round and uniform.

It also works with one vertical slit and one horizontal slit.

With the LED there also seems to be a 'solid' looking 'bar' at the centre of the pattern.

------

31. Can I use the oscillation frequency equation for this circuit?

It's more like the circuit sets R2 0$Omega$. The consequence of this is that the first 555 will have a very short output pulse, and that it may not be very reliable over temperature and part variations.The equation for oscillation frequency should still be accurate if you plug in a zero value for R2, though.

------

32. Canon printer wont scan please help with this?

The Canon combined printer/scanner must be present in the device managers list for imaging devices. Under properties the driver tab should show Canon as the supplier. Without the driver or the device in the list no software will be able to scan. You can still print because that uses a different driver. End line is to reinstall the Canon drivers

------

33. Which one is the best suplier of led grow lights?

I only believe in getting LED bulbs because they are not any more expensive, they have much lower electricity consumption and they provide a much higher quality light than any of the other types of grow lights. If you are looking for where to buy grow lights, Rick, you should take a look at these suggestions here:

How One Should Treat M.Kline's Mathematics. the Loss of Certainty?
The following statement is attributed to Hilbert:"Taking the principle of excluded middle from the mathematician would be the same, say, as proscribing the telescope to the astronomer or to the boxer the use of his fists. To prohibit existence statements and the principle of excluded middle is tantamount to relinquishing the science of mathematics altogether."I do not know the original source of this quotation, but have a look wikipedia.org/wiki/Brouwer%E2%80%93Hilbert_ (p. 24) think the quotation is authentic - it is consistent to what we know about Hilbert. In fact, Hilbert felt personally offended by Brouwer and (Hilbert's own student!) Hermann Weyl who supported Brouwer. Let me quote from :"The main opponent was the intuitionist school, led by L. E. J. Brouwer, which resolutely discarded formalism as a meaningless game with symbols (van Dalen, 2008). The fight was acrimonious. In 1920 Hilbert succeeded in having Brouwer, whom he considered a threat to mathematics, removed from the editorial board of Mathematische Annalen, the leading mathematical journal of the time."• Related QuestionsCan the German success on the Eastern front be largely explained by superior air power?I would not say so.The German advantage was in a superior doctrine and training at all levels, as well as better communications (availability of radios).Their officers and soldiers (infantry, tankers, pilots) spent more time in training before arriving at the front and they were taught a better tactics.Of course, using Stukas as flying artillery gave them extra advantage, which disappeared in, say, street fighting in Stalingrad, but that was far from the only strength they had.The German advantages eroded with time, as they lost more and more experienced soldiers and could no longer afford to teach new pilots for 2 years. Also, the Soviets "learned on the job" how to fight the Germans, and received many thousands of radios from the US.Whatever advantage Germany might have had in aviation, it was dramatically reduced by Goering's ego - his famous pronouncement "whatever flies is mine". In all armies tactical air forces were subordinate to the local ground commanders. E.g., (almost) every Soviet Front (Army Group) "owned" an Air Army and the Front commander could assign Air Divisions to his Armies to provide tactical support. He was also responsible for the logistics of his Air Army. Same with all the other combatants ever since - except for the Luftwaffe, where Army Group commanders had to communicate with their Luftflotte commanders through the OKL------Cheap prices for interior neon lights and led lights?for an identical reason I nonetheless force a 1997 BMW 528i (which nonetheless seems and handles like that is kind-new regardless of 215,000 miles on it) - the automobiles are geared up to final. the yankee manufacturers and almost all of their products have been geared up per a learn that found maximum individuals are keen to sell or commerce their automobile after possessing it for 3-5 years. as a effect, the product high quality is particularly sturdy on the fast run, yet toughness is particularly much non-existent. Why do no longer a brilliant form of the imported manufacturers do an identical project? because of the fact they take exhilaration of their product; whilst something breaks, they take it like a private failure and could circulate heaven and earth to restoration it, no longer merely for you, yet greater importantly to be sure it does not take place in destiny fashions. it is likewise by way of this that particularly plenty everyone in my kinfolk, and almost all of those that have ever pushed a BMW, Mercedes, Audi or Porsche keeps to purchase German. the jap corporation Nissan has an identical recognition besides. i does not evaluate the jap automobiles "greater desirable" as an entire, however. lots of them are absolute crap, and the main properly known distinction is that the jap companies furnish a bigger variety of machines in terms of high quality------Would anybody recommend a Linear LED light supplier in China?Honestly, there are a plethora of LED lights suppliers in China but you won't find many suppliers of Linear LED lights. I have been using LED linear lights for over a year now and I sourced all my linear LED lighting from China. Now, I'd like to share my pleasant buying experience with a China-based LED light supplier.Last years, I decided to replace my home-office lighting with specially designed LED linear lightssince they possess special power-saving features. While researching I came across SeniorLED on Instagram. The brand is quite popular on the internet and recommended by global LED lighting buyers. After visiting their site and browsing a vast catalog of indoor-outdoor LED lights, I opted for Linear LED lights and bought 20 pcs. The product quality and technical specifications are great. AIG insurance and 5 years brand warranty are cherries on the top. Interestingly, my office's energy bill reduced by 15% in a month of use.Here are some of the features which I liked the most:Lamp efficiency of more than 130 lumens per wattEquipped with cold-forging aluminum with 3D structureIP65 water-resistant featureSpecial energy-saving features7 kinds of reflectorsAuto-dimming featuresLonger lifespan and superior illuminationAIG Liability InsuranceMade from environment-friendly materialsCheck out this Quora answer about the best LED suppliers in ChinaVarun Sharma's answer to What companies in China sell the best LED lights?------LED light is on when it should not beWhat you have done is connected the LED lights in parallel to the switch. This way, when the switch is on, the LEDs are shorted out and power flows to the pot lights. When the switch is off, you end up effectively with the LEDs and the pot lights in series. Because the LEDs are so low power, the power flows through the pot lights without giving them enough power to visibly light.Check your switch box to see if there is a neutral wire there (probably white if youre in the US). If so, you can connect the LED driver between that and one side of the switch. If you dont have a neutral wire there, youll need to run a cable from a pot light to the LED driver. Connect it in parallel with the pot light.One more comment. Im assuming that the LED driver board is not designed to be in a junction box. Doing what youre doing is probably against the electrical code (at least in the US) and could be dangerous, especially if the board shorts out to the box. If this causes a fire, your insurance may have grounds to not pay, or at least to drop you afterwards------Why was X-Men Evolution cancelled?Well, there were some rumours why this show was cancelled. Some claims that it wasn't cancelled but ended. However, the show producer Boyd Kirkland thought of cancelling the show because there was a conflict between management and financing partner regarding the budget for the show.From Knows Why article,Although many have claimed that the reason for the cancellation of X-Men Evolution was not really explained, many have speculated that the show was cancelled because the producers just felt the need of ending the show despite its high ratings. Others also claimed that the series was not cancelled but it was just the end of the series per se. In true light however, show producer Boyd Kirkland thought of cancelling X-Men Evolution because there was a conflict between the management and their financing partner regarding the finances involved in the production of the series. With a monthly budget of $350,000, agreements did not turn out to work well that Marvel opted to cancel the show. Although the show was able to attract a lot of viewers, especially teenagers and adolescents, the predicament faced by the producers and the management led them to cancel the show. Even the publishing of the X-Men Evolutions comic book was abruptly cancelled since its sales were found to be significantly low.------What is the most cost efficient lighting for the house?The most cost efficient lighting for the house is LED Lights products. LED Lights is popular nowadays because this light is more energy efficient lights for the house. In LED Lights products there are different variants of LED Lights like Indoor LED Lights and Outdoor LED Lights. We use Indoor LED Lights for the house and in these lights, there is a different variant of light like LED Bulbs, LED Tube Lights, LED Downlights, LED Panel Lights, LED Strip Lights, LED Flush Mount Fixtures, LED Cooler Tubes, and LED Vanity Mirror.

If you want to know more about a specific product then you can check out LEDMyplace.Thank You.What is the most cost efficient lighting for the house?------Looking for learning resources to teach the principles rather than follow this projects closedI see people are voting to close this as too broad. Well, it is broad, but I'll try to give you some pointers. I used to wonder this stuff too, like "why use 10k and not 20k or 5k?". A good starting point is to watch some of Dave Jones' EEVblog videos.For example Designing a Li-Ion Battery Gauge with the LM3914 - EEVblog #204 - this is already 5 years old. He has done a lot of them. This particular one describes using the LM3914 chip to make a battery gauge, and in the middle he works through the resistor values using Ohm's Law.Another entertaining and informative blog is Afrotechmods. He also goes into detail but in a humorous way.Also try M J Lorton's blog.My only problem with videos is, if you are trying to reproduce some of their stuff you end up having to rewatch a (perhaps lengthy) video and pause it from time to time to copy stuff off the screen.For this reason I made some posts of my own on the Electronics part of my own forum. (Some of the more popular ones are also here in Stack Exchange as reference questions, for example How do you use SPI on an Arduino?).You could also look at the Adafruit and Sparkfun tutorials (amongst many others).
Can a Wizard Learn to Cast Cure Light Wounds From a Bard Scroll?
The Dragon #298 Sage Advice column "Official Answers to Your Questions" includes this exchange:Question: Is it possible for wizards to cast curative spells? For example, cure moderate wounds or cure light wounds? It seems that they can under the right circumstances. Suppose Willie, a halfling bard in my party, has the Scribe Scroll feat. The Player's Handbook says wizards, sorcerers, and bards all cast arcane magic. That means the cure spells a bard casts are arcane and not divine regardless of what the spell is, right? That also means that if Willie scribes a scroll with cure light wounds on it, the scroll will still be an arcane scroll. If that's correct, it means that if my wizard gets the cure light wounds scroll from Willie, he can scribe it into his spell book and then prepare it as an arcane spell that he can use time and time again, right?Answer: You can't read a spell off a scroll unless the spell is on your class list (see page 203 in the Dungeon Master's Guide). You also cannot scribe a spell into your book unless its sic on your class list. Only another bard can use Willie's cure light wounds scrolls (because bards are the only arcane casters who have cure spells on their class lists).Remember that spell trigger items, such as wands, do not come in arcane or divine versions. If a bard makes a wand of cure light wounds, any character who has cure light wounds on his spell list can use the wand. (112)This ruling predates the Dungeons and Dragons 3.5 revision, but as the topic's remained unmentioned since then (so far as I could determine, anyway), this ruling should be applicable to any 3.5 campaign with minor revisions by the DM (DMG (2003) 4). Although then-Sage Skip Williams's Rules of the Game columns should be read with salt shaker in hand, he's still one of the three primary designers of Dungeons and Dragons, Third Edition, giving this ruling at least some credibility. (By the way, at the time, Dragon was still published by Wizards of the Coast, not Paizo, if that makes a difference in determining if something's authoritative enough for your group.)A wizard that acquires an arcane scroll of cure light wounds conj (PH 215-6) (1st-level spell at caster level 2) (DMG 239) (50 gp; 0 lbs.) or even a divine scroll of cure light wounds conj (PH 216-7) (1st-level spell at caster level 1) (DMG 241) (25 gp; 0 lbs.) must follow these steps to get it into his spellbook:For this to work, the DM must rule that the wizard is not activating the spell (which is what happens when the spell on the scroll is cast)the wizard can't do that because to activate the spell on the scroll both the "spell must be of the correct type" and a wizard "must have the spell on his or her class list" (DMG 239).Instead, the DM must rule that using the scroll to add the spell to his spellbook is a different process that doesn't so much as activate the spell but, like, readies the spell for transcription or something. Nonetheless, when this this different process is used, "a spell successfully copied from a magic scroll disappears from the parchment" (179). Such a ruling isn't, in itself, a huge leap for the DM to make, but it's not an inconsequential one either, so a player asking the DM about such a distinction should make clear his reason for asking.The Player's Handbook on Spell Preparation Time says, "After resting, a wizard must study her spellbook to prepare any spells that day" (178). That is, if a spell's in the wizard's personal spellbook, the spell's already gone through the process above (or a similar process that's led to the spell being in the wizard's spellbook). Nothing prevents the preparation of any spell in the wizard's spellbookeven if the spell's source is weird or its typical list alien.The wizard class feature spells says, "A wizard casts arcane spells... which are drawn from the sorcerer/wizard spell list" (PH 56). While the text doesn't say a wizard can't cast spells from lists other than the sorcerer/wizard spell list, the game usually uses inclusive language (explaining what can be done), saving for confusing corner cases exclusive language (explaining what can't be done). That is, just because the text doesn't say the wizard can't doesn't mean the wizard can, for example, turn his foes into lawn furniture (at least until the wizard can cast polymorph any object, anyway).Hence, with a generous DM, a wizard can understand and copy from a scroll any spell into his spellbook, and a wizard can even prepare that spell if he has a spell slot of the appropriate level, but the wizard can't cast the spell unless it's on the sorcerer/wizard spell list.Again, with a generous DM, it's possible that such prepared-but-uncastable spells could still be used, for example, during item creation; that is, the item creation process often "triggers" spellsthe prepared spell's expended as if the spell were cast but the spell's not actually cast. So using that generous DM's rulings, such a wizard could, for example, createbut, oddly, still not normally usea wand of cure light wounds.Also, when a wizard that has added to his spellbook the spell cure light wounds from a divine scroll of cure light wounds then creates his own scroll of cure light wounds, the DM must decide whether the resultant cure light wounds spell on that scroll is arcane or divine, because, honestly, I have no idea, and, really, if you've such a generous DM that you've gotten this far, why are you trying to make his head explode? Neither could that wizard normally use that (arcane? divine?) scroll of cure light wounds. Seriously, do that nice DM a solid and just brew a darn potion.Of course, none of this precludes a wizard from employing in whatever capacity off-list spells that that specific wizard has somehow uniquely added to his wizard's spell list. In that case, the spells aren't off-list anymore, so it doesn't matterIf a bard were to scribe Cure Light Wounds into a scroll, would it be possible for a Wizard to write it into his spellbook given that it's the arcane version of the spell?I know about Can a Sorcerer learn "Cure Light Wounds" from a scroll?, but I'm unsure if the rules are different when dealing with a Wizard versus a Sorcerer.·OTHER ANSWER:If a bard were to scribe Cure Light Wounds into a scroll, would it be possible for a Wizard to write it into his spellbook given that it's the arcane version of the spell?I know about Can a Sorcerer learn "Cure Light Wounds" from a scroll?, but I'm unsure if the rules are different when dealing with a Wizard versus a Sorcerer.
Frequently Asked Questions (FAQ) for Led Light Book
1. What is causing a white scale buildup at copper pin connection on LED light sticks and how can they be cleaned?Copper is a material that corrodes, just like any other. When copper corrodes, it will turn into copper carbonate (Cu2CO3(OH)2), but near the sea it might become copper chloride (Cu2(OH)3Cl) as well. When water is involved, like in your case, there may be an effect called efflorescence. Efflorescence "is the migration of a salt to the surface of a porous material, where it forms a coating". This usually forms in a crystal form, since it's formed of salt. This is what creates the white buildup sometimes found on water pipes for example: your case it's the same:So basically, you're getting water infiltration. The easiest solution to solve this is using dielectric grease. Or get a better seal for your electronics.------2. where to buy best and cheapest LED panels lighting?LED panel light uses high brightness LED as light source, which is suitable for hotel, bar,western restaurant, coffee shop, home interior decoration, interior lighting, and can directly replace the original ordinary fluorescent lamps, and its brightness is higher. Main performance and features of the LED instrument panel lights are as follows: LED panel lights are designed to be flexible LED is a point like luminous body, the designers design a variety of different shapes,different particles of the light source according to customer requirements by the flexible combination of point, line and surface, the design is very flexible. LED panel lighting illumination is high LED panel lights use uniform light-emitting reflective panel and sealed design, coupled with efficient light guide plate, and aluminum alloy material. Glow is even and illumination ishigher.------3. led lights for aquarium?Maybe you can search in the Internet,the network to find suppliers is a tide, can easily find it. But you should pay attention to some skills. LED light aquarium can be installed inside aquariums to supply lighting effects to the fish as well as plants. Theyre usually designed such as a long, slim stick, that might be positioned over head or even in back of the fish tank. Additionally, electronic shops offer LED spotlights which have been designed like a shower-head. These are also available in more compact, node-like lamps which have been divided through various shades of diodes. Give some details about the led lights for aquarium. There is also a website which is specialized in the led lights for aquarium.Hopping the websites can give a little help for you.------4. Should the use of LED light bulbs be banned in automobile headlights?If by "LED bulbs" you mean aftermarket replacement parts for halogen headlights, those are already technically violating the law because using those bulbs, which have a different shape for the light emitting surfaces compared to the factory lamp change the angular distribution of the headlight in a way that causes the headlight pattern to no longer comply with DOT rules (headlight intensity becomes to high and too much light is thrown above horizontal). Is a similar problem as illegal HID conversion kits that were popular 10 years ago.I'd like to see more enforcement of current rules against the use of dazzling lights. But I wouldn't ban an entire technology (LEDs) when said technology *can* be designed in a way that doesn't have those problems.Should the use of LED light bulbs be banned in automobile headlights?------5. Is using a (non-touch-screen) Kindle on Shabbat permitted?Aside from the electricity needed to change pages, I think the melacha that e-ink runs into is Tzovei'a (dyeing). You are not allowed to paint things, and color things, and dye things on Shabbat.The Kindle uses an Electrophoretic display, where basically, reflective titanium particles are suspended in a dark fluid. They are electrically charged to move to the from the front sheet of the display where they would appear white, to the back of sheet of the display, letting us see the dark ink. Pressing a button sends an electric signal to change their charges.That being said, there is a possibility that it is not dyeing.On transition eye-glass lenses, Chacham Ovadia said that they are permissible since it is not a normal way to dye.------6. Which LED light manufacturer do you think is the most trusted among other manufacturer?LEDs emit easy in a particular direction, lowering the will for reflectors and diffusers which could seize easy. this selection makes LEDs greater effective for many makes use of including recessed downlights and activity lighting fixtures. With different varieties of lighting fixtures, the sunshine would desire to be contemplated to the needed direction and greater desirable than a million/2 of the sunshine would in no way leave the fixture. the sunshine would desire to be of extraordinary coloration, with a brightness a minimum of as super as customary easy supplies and performance a minimum of as super as fluorescent lighting fixtures. The LEDs would desire to additionally eliminate darkness from promptly whilst grew to become on, shouldn't flicker whilst dimmed and should no longer consume any means whilst grew to become off------7. Can I connect an LED light fixture to a 240 volt oulet?Below is based on US 120V/240V system:An ordinary device (not talking about a tester that has access to hot/neutral/ground) can't actually tell the difference between hot/hot vs. hot/neutral. There is no polarity in AC as there is in DC. From a practical standpoint, it comes down to voltage requirements:So for a device that can use the entire range 120V to 240V (e.g., 100V - 277V), either one will work just fine. The exceptions come in three flavors:Bottom line: If the device (light fixture but sometimes other things such as computer power supplies) only uses two wires (plus ground, of course) and has flexible voltage (from 240V) then you can connect it to two hots instead of hot neutral------8. Low cost reptile lighting/LED lighting?First, you need to understand why you need the lighting in the first place. Does the reptile need full spectrum lighting for health, such as the absorption of calcium? Or does it just need light for day and night length cycles? It is easy enough to assemble an LED lighting system if you buy the pieces individually off electronic suppliers on the internet. You can buy the individual bulbs and electronic boards to arrange them in. Solder them together in a linear or pairwise fashion, depending on how efficient you want to current to be and how much soldering you want to do, then supply electricity. Price-wise though, this can still be a little much. Almost all LED systems have to be assembled by hand, which accounts for most of the cost.------9. Fog Light LED doesnt fit within housing?basically on the returned the place they do some thing clever. I even have had automobiles with fog lights furniture on the front as many times happening equipment yet under no circumstances observed any benefit over using the dipped head lamps. i think they might help oncoming motorists to be certain you in dense fog yet, if the fog is thick sufficient for that to count, all human beings must be going very slowly besides so as that they are going to see you in rather some time. in the united kingdom it rather is unlawful to apply fog lights furniture different than in fog. some human beings nonetheless do it it relatively is stressful yet has the earnings of offering a warning different highway shoppers that the offending automobile is being pushed via a tosser------10. HDD Blinking LED light?Typically the electronics of the device may be corrupt or it may even be a hardware problem and something has come loose. To fix this problem send the device in to have it checked if its still under warranty. Or for a do-it-yourself solution, you can replace the external case of the portable hard drive with something sturdier or more reliable. The first thing that usually, "goes", in portable drives is the interface connector between the cable and the drive. The flashing lights usually indicate power, and hard drive operation. In your scenario it seems to be indicating a code of a sort and it may be an indication of a hardware malfunction. Read the suggestion or fix indicate on their website regarding the flashing code this indicator may be indicating.------11. What gauge wire for long run from power supply to LED light strip?Is 5050 the model number or the quantity of leds?The cable you linked to looks very lightweight - you don't need a lot of copper to run leds directly off of low voltage DC but you do need to handle it a lot during installation.I would get something heavier, just for the mechanical advantage. 16AWG stranded 300 volt should do nicely, the voltage rating is to get thicker insulation. You can get spools of it in many colours from any electronics supplier (not electrical, "electronics") in the local phone book. Also pick up an automatic wire stripper and a decent crimping tool while you are there - the common stamped-steel crimpers do NOT do a good job, and you don't want to have to get in behind the walls twice------12. My HP Pavillion a1140n will not power up. The led light does not come on, but the disk drive lights up.?in basic terms unlawful to rigidity with highbeams in the direction of oncoming site visitors. It creates a protection probability - by potential of blinding oncoming drivers. Flashing your lighting fixtures furnishings, no remember if intense beams or perhaps in simple terms turning your lighting fixtures furnishings on and rancid is likewise unlawful. lower back, it ought to create a protection probability by potential of blinding or perhaps complicated different drivers. additionally, flashing lighting fixtures furnishings are reserved for emergency automobiles in basic terms. it extremely is the regulation, even nonetheless i do no longer think of a cop grant you with a cost tag for flashing your lighting fixtures furnishings. yet, you will get a cost tag for driving mutually with your intense beams on, in case you get caught------13. How do I wire LED light based zone for DALI dimming? closedNearly all drivers on the market will only occupy one "short address" even if they can drive multiple LEDs, lamps or tubes, so they will drive them to the same level. Any driver which is different, occupying multiple "short addresses" would probably make that clear in their information since it is unusual although valid.How you split up your downlights over different drivers depends on what level of control you want. If you will never need to control the downlights independently, then you can wire them all to the biggest driver you can find, or in groups limited by the driver capability but either way, in broadcast mode, all together. If you want individual downlight control, you need an address per downlight, which means a driver per downlight, and some way of setting up the addresses------14. What is a convex polyhedron?As other have said, a convex shape is one where the straight line connecting any two points is entirely within the shape.The Euler characteristic tells you something about the topological shape of the solid in question. By topological I mean you can distort things without changing the Euler characteristic, but no cutting or gluing. So a tetrahedron or a cube are essentially the same shape - you can make either out of a ball of putty just by flattening appropriate places - and have the same Euler characteristic. But if you imagine drilling a square hole through a cube, this would make a different type of solid - instead of a ball, it's sort of like a donut - and this has a different Euler characteristic (you should find $FV-E0$, not $2$)------15. Why does a LED light up in reverse direction at a DC generator worked by a falling objectYour diode is acting as a Flyback Diode, also called an "inductive kickback" diode.When current is flowing through the inductor (motor, generator, etc), a magnetic field is maintained. When the circuit is no longer excited the field collapses, which acts to oppose the change in current. This created a voltage spike ("inductive kick") on the previously-negative side of the inductor.The LED is the easiest path for current to flow, to alleviate the high voltage. What you are seeing is the inductive kick being snubbed by that LED.In electronics, any time you are switching an inductive load, you need to put these diodes in place. The kick can (and will) destroy transistors, MOSFETs, and even relays contacts. Usually you use a Schottky diode, because of the lower forward voltage. But then you can't see it light up :).

The most important thing is to know what kind of bulb you are using and what kind of bulb you are using.
IGBT of Fuji Motor Electronic Equipment Technology
IGBT of Fuji Motor Electronic Equipment Technology
The IGBT technology of Fuji motor and electronic equipment technology has been commercialized since 1988 and has been supplied in the market so far. Figure 1-3 shows the development process and application technology of IGBT products from the first generation to the fifth generation. Epitaxial wafers are used in the first to third generation IGBT, and the characteristics are improved by optimizing life cycle control and refinement technology of IGBT. Then, the fourth and fifth generation products have achieved significant characteristic improvement through the transition from epitaxial wafer to FZ (floating zone) wafer. In this regard, the design policy of IGBT has changed greatly compared with the past.Firstly, the basic design idea of IGBT using epitaxial wafer (series products up to 600V of the third to fourth generation, called "breakdown type") is as follows. In order to realize the low-pass state voltage during IGBT conduction, a large number of carriers are injected from the collector side to fill the IGBT with high concentration carriers. In addition, the n-buffer layer specially set to maintain the high voltage forms a very thin n-layer, so as to realize the low-pass state voltage. In order to realize fast exchange, life cycle control technology aiming at the rapid disappearance of carriers filled in IGBT is also adopted (through these, low exchange loss (eoff) can also be realized). However, once the life cycle control technology is applied, even in the normal on state, due to the effect of this technology (the carrier transport efficiency decreases), there is a problem of increasing the on state voltage, which can be solved by further high carrier injection.In short, the basic design concept of IGBT using epitaxial wafer technology can be simply summarized as "high injection and low transmission efficiency". In contrast, IGBTs using FZ wafers (series after the fourth generation 1200V) adopt a reverse basic design to inhibit the injection of carriers from the collector side and improve the transmission efficiency by reducing the injection efficiency. In the above-mentioned design concept of IGBT using epitaxial wafer "high injection and low transmission efficiency", the carriers that are not easy to be injected are forcibly suppressed through the control of life cycle, which not only limits the improvement of characteristics, but also increases the standard deviation of on-state voltage characteristics through the control of life cycle, It is very disadvantageous to the large capacity required for parallel use with increasing requirements in recent years. The technology developed to overcome this problem is a new IGBT using FZ chip (NPT: non punch through (used from the fourth generation IGBT) / FS: field stop (used from the fifth generation IGBT) - IGBT). The IGBT does not adopt life cycle control. Its basic design idea is to control the impurity concentration of the collector (P layer), so as to inhibit the carrier injection efficiency. However, in order to realize the characteristics superior to the IGBT using epitaxial wafer, it is also required to realize more than one hundred for the 1200V high voltage resistant series IGBT μ M (the thickness of n-layer in NPT and fs-igbt using FZ wafer ≈ the thickness of chip (wafer). The thinner the thickness, the lower the on state voltage can be generated). In short, it is not too much to call the development of IGBT using FZ chip a challenge to chip thickness.Fuji electric and electronic equipment technology has solved these problems. Starting from the fourth generation 1200V series - IGBT, it has realized the commercialization of "s series" constructed by FZ chip NPT. In addition, 600V series technology with higher thickness requirements is further developed, and 600v-u2 series (fifth generation) is being commercialized. In addition, in 1200V series - the fifth generation "U Series", in order to improve the performance better than s series, NPT structure has been changed to FS structure.The so-called FS structure does not use the life cycle control technology. While following the basic design concept of "low injection and high transport efficiency" of carriers, an n buffer layer to maintain voltage is set on the FZ wafer, so as to realize the IGBT structure thinner than the NPT structure. Through this change, 1200v-u series realizes the low on state voltage characteristic better than s series, and completes its commercialization. In addition, this technology is also used in 1700V series high voltage withstand series, and is also starting to be commercialized.Figure 1-3 changes of Fuji motor electronic equipment IGBT application technologyIn addition, Fuji electric and electronic equipment technology is also refining the surface structure indispensable for the improvement of IGBT characteristics (IGBT is formed by multiple IGBT plates. Through refinement, the more plates, the more low on-state voltage can be realized). Up to the fourth generation products, the planar structure (the structure of planar IGBT) has been used to promote refinement, so as to improve the characteristics. However, starting from the fifth generation products - 1200 and 1700V series, the grooved IGBT technology slotted on the Si surface and constituting IGBT has broken the subtle technical barrier and achieved unprecedented characteristic improvement. Figure 1-4 shows the change of characteristic improvement of 1200V series.Figure 1-4 improvement of balance characteristics
Is a Metal Roof Right for You | Billy
Is a Metal Roof Right for You | Billy
Is a Metal Roof Right for You | BillyMetal roofs, first popularized in the 19th century, have enjoyed a long history in American culture, and are now enjoying a resurgence in home building and restoration due to the growing popularity of both industrial and farmhouse styles. Tin roofs were commonly used for homes and barns in the south and are still fairly common in states like Ohio, but these have been replaced by milled steel and more modern materials. Modern metal roofing comes in several gauges and a variety of finishes and styles to complement your house and yard. Exposed and hidden fastener roofs are available with seamless standing (hidden) being a favorite among architects. Seamed roofs require visible grommet screws , whereas the seamless-style roofs involve a different type of concealed-fasterner installation. Standing seamless roofs generally have more robust trim. Traditionally, metal roofs consisted of vertically oriented panels with vertical seams. Modern technology had yielded an abundance of other profiles, many mimicking other roofing types. Read on for more information. Early American metal roofs were often painted for preservation and new roofing improves upon that with durable powder-coated and other advanced finishes. A range of metallic finishes are available to mimic metals such as copper and galvanized metal. A "traditional" red oxide complements barns and imparts a rustic look to older buildings or even newer homes. Imagine a square schoolhouse with a stark barn red roof. Grays, blues and certain greens are also manufactured with hunter-type greens pairing well with cabins and other rustic homes. If you like old-fashioned, galvanized roofing, there is a zinc and aluminum-impregnated panel called galvalume that offers great longevity and an attractive sheen. Note that galvalume is a different process than painting and usually has a slightly different warranty. While traditional shingles only come in subdued colors, painted metal finishes are available in vivid primary and secondary colors, making them ideal for the modern and adventurous. These tough finishes generally come with a warranty that ranges from 25-40 years. Ask your contractor for samples or order some online from manufacturers. There are a lot of profiles available for metal roofs from more architectural, flat-ribbed modern types to more classic, simple rib styles like those found on barns (and in the old rural South). If you can get a contractor to bring larger samples and see them on top of your roof, it becomes much easier for you to visualize your roof job. It's possible that a modern standing seam roof will make a nice contrast to an older farm or that a more traditional style will add some excitement to a newer home. Do not be afraid to get experimental. Along with vertically-oriented roofs, shake, tile and shingle-style metal roofs are gaining popularity in the construction field. Clay tile roofs are difficult to replace, and modern roofing materials are frequently being used on historic buildings (where historic preservation is not an issue). These metal styles are also useful for additions as they can provide contrast to other building materials for a melding of styles or postmodern appearance. Metal roofing materials are, in fact, candy for architects and other designers as they search for new architectural expressions. Metal roofing is not limited to interiors either. You will find them used creatively in home (and business) interiors as ceilings (check the indoor rating), as partial walls, and for components of industrial-style furniture. One of the big advantages of a metal roof is that it has a much greater life expectancy than a shingle roof. The metal itself can last 50-100 years-way beyond any asphalt shingle (with a 10-15-year average life expectancy). However, the paint finishes are rated for fewer years (30-45-still a great warranty) and you may decide you have to repaint your roof after 30 or 40 years. If that is the case, there are good paints available for painting metal, as well as technicians who know how to prep and paint it. That said, metal will still outlast any asphalt shingle. Metal roofs generally cost more than shingle ones, however, the long-term value, as stated above is much greater, making the overall expense less. Also, the cost of a metal roof varies from state to state. Generally, there are more contractors skilled in metal roof installation in states such as Ohio where they are more common. Be sure to get multiple quotes if you are considering a metal roof. Screwed roofs are less expensive than standing seam but, as previously mentioned, may mean you need to have it inspected for loose fasteners on occasion. The cost for roofs varies so much, that you will really need to get estimates from local contractors to determine if a metal roof is right for you. Standing seam roofing generally has prominent ribs and interlocking, hidden-clip-fastened seams and the fastening system and trim are completely different than those of the screw-in type (the latter found commonly on barns). There are reasons you might choose one or the other, however. Obviously, if you want clean lines with no exposed fasteners, standing seam is for you. Standing seam roofs tend to show imperfections and may appear wavy or reflect light that accentuates those imperfections, or even waviness in the roofing itself. An old roof with a lot of sagging will highlight this aspect. Corrugated roofing or most visible-screw types of roofing may better conceal imperfections. The gauge of the metal also impacts how well the roofing conceals the underlying structure. If you are looking for a more industrial look, you might appreciate the exposed fasteners on the screw-fastened sheets. Exposed screw roofs are generally less costly than standing seam but when installed properly, both are good options for your home. Metal roofs come in several gauges, 29, 26 and 24, with the higher numbers being the thinnest material, and the lowest number being the most durable. Make sure you know the recommendations for residential applications before signing a contract with a roofer. 29 gauge may be used for most residential applications, but for severe weather areas, 24 might be better. Some professionals recommend 26 gauge for homes and 29 for barns and other outbuildings. There may be local code requirements as well. One way that a contractor might cut corners is by using a really thin-gauge metal on your home. The most practical advantage is that you likely will not have to replace a metal roof in your lifetime, provided you are happy with the color and paint. If you tire of it, you, of course, can have it painted, which should not be a huge expense. Shingles, on the other hand, need replacing every 15 years or so. Even the newer dimensional shingles are still going to require replacing and maintenance. Most people with asphalt shingles have, at one time or another, had them blow off in a storm. A metal roof can occasionally suffer from storm damage in hail or really high winds, but not to the same extent as asphalt shingles. Some insurance companies even give you a break if you install a metal roof (this is not likely in coastal areas, however). Chalking and fading may be an issue for metal roofs down the road. However, there are government standards for acceptable fade amounts which can usually be found on the manufacturer's website. This refers back to the issue of painting. Metal roofs are faster to install, depending on the skill of contractor. Need a roof fast? Do you have severe storm damage? Metal might for you then, provided it appeals to you aesthetically and you can find skilled tradespeople in your area. Metal roofs are much lighter than shingles, meaning less stress on the roofing structure (and the workers). If you are building from scratch, or using for a garage or shed, the requirement for supports may be reduced. Check your local building codes for more information. As previously mentioned, metal roofs are more cost effective than shingle ones in the long term, given the lower life expectancy of shingled roofs. The best way to calculate cost effectiveness is to get some actual quotes from roofers with the knowledge that many roofers will try to talk you out of a metal roof for the simple reason they do not know how to install them. It is a specialty skill and, depending on your location, there may not be many installers. For many homeowners, some of the decision will boil down to aesthetics. People tend to either really like or really hate the appearance. Be sure to ask yourself the following: • Will I love this roof and its color in 20 years? • Will I keep this home or sell it? • Are there any other governing bodies or local codes I need to be aware of before installing? One of the biggest concerns you read about metal roofs is if they are noisy. People might claim the pinging keeps them awake. Conversely, some describe the noise as romantic. Installed over roofing underlayment (plywood), a metal roof is not going to have the same acoustics as, say, a barn with no underlayment, which can be extremely loud when it rains. If this is a concern, you can request a thin layer of foam insulation placed over the existing roof (and beneath the metal roof panels), as it dampens the sound. Foam insulation will also reduce the imperfections that might show through the roof (especially on standing seam, non-corrugated roofing). A huge advantage to metal roofs, and one that you seldom see referenced online, is how well they hold up to snow. While standing snow on asphalt can cause damage and leaking (thus the need for roof snow rakes), metal roof owners will be pleased when, as the sun heats the roof up, they hear the whoosh of a small avalanche as the snow slides off the house onto the ground. Of course, you will probably want to remove this snow from around your foundation, but it beats having to rake it off. Because metal is not combustible, many metal roofs have a really high fire rating (class A). Of course, the materials used beneath the roof also impact the rating. For instance, if you did not tear off the asphalt shingles before installing the metal, they would be included in your combined fire rating. Metal, unlike wood or asphalt shingles, is resistant to mold, rotting and insect infestations. As long as it's properly installed, it should last as long as your house. A variety of paint finishes are available, from subdued neutrals, to metallic copper, to bright primary colored paints, making it versatile for both historic and modern homes. The long-term cost beats most other roofing materials, making it a good roof for the long-term home owner. If you buy a metal roof, buy it because you love it, as you are the one who is going to be enjoying it each time you pull in your driveway or spend time outside.

You never know on the day.— — — — — —what paper for water color paintings?D'Arches would be your best bet for watercolours. If you are not going to spend that much on your surface then go to an art store and buy a paper of a weight no less than 120 lbs. The paper weight means that with one hundred sheets of that size the package weighs 120 lbs. Any thing lower than that weight is rather dicey for watercolours although I have worked a lot on 90 lbs paper it is not as good to stretch. Be advised that you have two types of pressed papers to work with. A cold press is very rough on the surface, that is to say that it has a large tooth to the paper. A hot press is a very smooth paper. Further more, if you are buying in single sheets find the water mark before you do anything. The water mark is visible by holding the sheet up to a strong light and you can usually find it in the lower right hand corner. It will stand out lighter than the paper around it and you can see the name of the company or the company logo. If it looks backwards then you have the wrong side to paint on. The face of the sheet that you can see the watermark correctly is the proper side to work on. It takes the colour more readily than the backside and has been groomed for your paint. Always paint on the face of the sheet where the water mark is. If you are halving the sheet, then mark the proper face with a slight mark of a 2H pencil to show the proper face on the halved sheet that does not have the watermark. There are also watercolour pads that can be procured at stores like Staples. They are blocks of paper bound together on one pad by a strong rubber seal on all four sides and this assists in the drying of the paper. When you paint in water your paper will warp, and go into valleys and hills so to speak. If the paper is not stretched properly it will dry that way, but these pads will keep the paper taught so that when it does dry the paper will draw taught again flattening itself out. One word of encouragement though. Water colour is one of the most difficult mediums to master. It looks simple but simple aint easy. So to allay any frustrations I will give you the first and cardinal rule of watercolours. " The first five-hundred watercolours you do? THEY DON'T COUNT". All the best to you.
