what exactly do you mean by led ? A brief explanation of how light-emitting diodes function. In its most basic form it is 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 that carry this current (known as holes and electrons) combine within this semiconductor substance. Because light is produced within the semiconductor solid LEDs are classified as solid-state electronics. Solid-state lighting that comprises organic LEDs (OLEDs) differentiates this lighting technology from the other lighting sources that rely on heating filaments (incandescent and tungsten lamp halogens) (or gas discharge) (fluorescent bulbs). Different colors Inside the semiconductors inside the LED the holes and electrons are contained within energy bands. The distance between the bands (i.e. that's the bandgap) determines the amount of intensi...
