what is the meaning by"led" ? A brief overview of how light-emitting diodes work. In its most basic form, it's a light-emitting device ( led full form ) is a semiconductor device that produces light when the current of electricity flows through it. The light is produced when the particles carrying the current (known as electrons and holes) mix inside this semiconductor substance. Because light is produced within the semiconductor solid LEDs , they are classified as solid-state electronics. Solid-state lighting, that includes organic LEDs (OLEDs) is a distinct lighting technology from other sources of light that rely on heated filaments (incandescent and tungsten lamp halogens) (or gas discharge) (fluorescent bulbs). Different colors Inside the semiconductor in the LED the holes and electrons are contained within energy bands. The distance between these bands (i.e. that's the bandgap) determines the intensity that photons (light particles) e...
