Bookmark or Share- LEDs: What Are They? (Definition, Types, and Uses)A LED or light-emitting diode is an electrical component that produces light when current passes through it. LEDs are semiconductor devices, light is produced when the electrons combine with the material used as the semiconductor. LEDs can come in a variety of different shapes, colours and sizes.
- 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.
- 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:
- Light Emitting Diode (LED): What is it & How Does it Work?Key learnings: LED Definition: A Light Emitting Diode (LED) is a semiconductor device that emits light when electric current flows through it. Working Principle of LED: The working principle of LED involves applying a forward bias current, which causes electrons and holes to recombine at the junction, producing light.
- What Is an LED? - How-To GeekAn OLED is a type of light-emitting diode (LED). OLEDs are made of organic materials that emit light when an electric current is passed through them. OLED displays are different from traditional LCD flat panel display because they do not require a backlight. Instead, each colored pixel emits light itself.
