NettetA photodiode is a PN-junction diode that consumes light energy to produce an electric current. Sometimes it is also called a photo-detector, a light detector, and photo-sensor. These diodes are particularly designed to work in reverse bias conditions, it means that the P-side of the photodiode is associated with the negative terminal of the ... NettetThe light-emitting diode, which is commonly known as LED is a basic P-N junction diode that emits light when the current flows through it in the forward biasing condition. LEDs …

LCDs consume much less power than LED and gas-display displays because they work on the principle of blocking light rather than emitting it. Construction of Liquid crystal display:
Nettet27. apr. 2024 · A compact fluorescent lamp (CFL) is a type of fluorescent lamp that has been compressed into the size of an ordinary incandescent lamp. It works on the principle of gas discharge, i.e., ionization of gas by the electric current. The modern CFL was invented by Edward E. Hammer in 1973. CFLs are the lamps of choice for those … NettetA light-emitting diode (LED) is a semiconductor device that emits light when an electric current flows through it.
