Bookmark or Share- What is LED? - Definition, Working, Properties, Uses, AdvantagesA light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it. When current passes through an LED, the electrons recombine with holes emitting light in the process. LEDs allow the current to flow in the forward direction and blocks the current in the reverse direction.
- Light-emitting diode - WikipediaLEDs are transducers of electricity into light. They operate in reverse of photodiodes, which convert light into electricity. The first LED was created by Soviet inventor Oleg Losev [9] in 1927, but electroluminescence was already known for 20 years, and relied on a diode made of silicon carbide.
- How Light Emitting Diodes (LEDs) 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.
- LEDs: What Are They? (Definition, Types, and Uses)We will start by taking a look at what LEDs actually are, the different types of LEDs, and the uses of LEDs. Finally, we will answer some of the most frequently asked questions about them. A LED or light-emitting diode is an electrical component that produces light when current passes through it.
- 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:
