Bookmark or Share- How Light Emitting Diodes Work | HowStuffWorksLight emitting diodes, commonly called LEDs, are real unsung heroes in the electronics world. They do many different jobs in all kinds of devices. They form numbers on digital clocks, transmit information from remote controls, light up watches and tell you when your appliances are turned on.
- Light-Emitting Diodes (LEDs) - SparkFun LearnLEDs (that's "ell-ee-dees") are a particular type of diode that convert electrical energy into light. In fact, LED stands for "Light Emitting Diode." (It does what it says on the tin!) And this is reflected in the similarity between the diode and LED schematic symbols: In short, LEDs are like tiny lightbulbs.
- Light-emitting diode - WikipediaA light-emitting diode ( LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons.
- Light Emitting Diode ＜What are LEDs and How Do They Work ... - RohmWhat are LEDs? LEDs are a type of semiconductor called "Light Emitting Diode". White LEDs, which have achieved practical realization through the use of high-brightness blue LEDs developed in 1993 based on Gallium Nitride, are attracting increased attention as a 4th type of light source. How do LEDs Emit Light?
- What Is an LED? - How-To GeekLEDs have many advantages over traditional light sources. For example, they last much longer. A traditional incandescent light bulb lasts about 1,000 hours, while an LED can last for 50,000 hours. This means that you would have to replace an LED only once every 10 years. LEDs are also more durable than traditional light sources.
