Each individual LED is rated having a greatest ahead present-day that's Risk-free to pass through it with no burning from the LED. Of course. Letting present-day greater than the rated existing will in fact burn off the LED.
Sep 3, 2012 Hello there, Aaronyana! Thanks for sharing your comment with us now! We're so happy to find out that you are performing some great Thinking of your own private-- and at times text that sound alike but necessarily mean various things could be confusing!
因為發光二極管為光源面積小、分佈較集中，作照明用途時會刺眼，須運用光學設計分散光源。
Aug 29, 2012 Hey there wonderopolis! I'm sorry to state but this video clip was genuinely terrible. It absolutely was simply a man snowboarding or no matter what he was undertaking. I love this Web site but don't like the matters as well as films, They're just so dull.
What's this magic? An LED by using a designed-in resistor? That's ideal. In addition there are LEDs that include a little, current restricting resistor. For those who search intently for the graphic underneath, there is a small, black square IC within the publish to Restrict The existing on these sorts of LEDs.
By the way, if you see the phrase led prepared in uppercase letters—LED—that’s an acronym that stands for “light emitting diode,” which is, as its name indicates, a diode that emits light.
Other search engines like google affiliate your ad-click on behavior by using a profile on you, which may be applied later to focus on ads for you on that search engine or all around the net.
Aug 28, 2012 Hey there, WONDERman, we have been so glad that you simply savored today's Surprise about LEDs! We considered the surfer did an awesome job turning corners and keeping harmony-- it appears like a tricky occupation!
LEDs use warmth sinks to soak up the warmth made by the LED and dissipate it in to the bordering setting. This retains LEDs from overheating and burning out. ecran led geant Thermal administration is generally the single most vital Think about the effective functionality of the LED around its life span.
Electrical power effectiveness is one of The key LED gentle benefits, but low servicing is another great gain. LEDs have an exceptionally very long lifespan of over 10 years mainly because there isn't a filament to burn out.
Confer with our LED lumens chart over to determine how LED bulbs Look at to other kinds of bulbs’ lumens-to-watts ratios.
Some kinds of LED lights are self-contained fixtures without bulbs to replace. This guideline outlines the characteristics and benefits of a variety of kinds of LED lights so yow will discover the most effective LED lights for your home.
發光二極管只能夠往一個方向導通（通電），叫作正向偏置；當電流流過時，電子與電洞（电子空穴）在其內复合而發出單色光，這叫“電致發光效應”；而光線的波長、顏色跟其所採用的半導體物料種類與故意摻入的元素雜質有關。發光二極管具有效率高、壽命長、不易破損、反應速度快、可靠性高等傳統光源不及的優點。
Which means LEDs can easily use gentle and Strength much more proficiently inside of a multitude of applications. Even so, In addition it means that advanced engineering is needed to supply an LED mild bulb that shines mild in each and every route.
