A light-emitting diode (LED) is a semiconductor device that emits visible light when an electric current passes through it. The light is not particularly bright, but in most LEDs it is monochromatic, occurring at a single wavelength.
Here are a few to apply LEDs in everyday life:
- Lamp Illumination.
- Street Lighting Lamps.
- Advertising boards (Advertising).
- Backlight LCD (TV, Mobile Display, Monitor).
- Interior and Exterior Lighting Decoration.
- Indicator Lights.
- Infrared transmitter on the Remote Control (TV, AC, AV Player)
- 4x Yellow LED
- 4x RedLED
- 4x BlueLED
