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
LED lighting differs from incandescent and fluorescent in several ways. When designed well, LED lighting is more efficient, versatile, and lasts longer. LEDs are âdirectionalâ light sources, which means they emit light in a specific direction, unlike incandescent and CFL, which emit light and heat in all directions. That means LEDs are able to use light and energy more efficiently in a multitude of applications. However, it also means that sophisticated engineering is needed to produce an LED light bulb that shines light in every direction.
