Led material used
NettetAn LED is a type of p n junction diode that works on the principle of electro-luminance. A material called electro-luminance is used to convert electrical energy into light energy which later helps in the propagation of light energy. When light is emitted in the front bias, it is called a light-emitting diode.

Nettet7. jun. 2024 · Diodes are semiconductor devices that allow current to flow in only one direction. Diodes act as rectifiers in electronic circuits, and also as efficient light emitters (in LEDs) and solar cells (in photovoltaics). The basic structure of a diode is a junction between a p-type and an n-type semiconductor, called a p-n junction.
