LED lighting technology and features

- Nov 15, 2017 -

The so-called LED lamps, as the name suggests, refers to the lamp products using LED (Light-emitting Diode, LED) technology as the main light source. LED is a solid state semiconductor components, the use of current flow through to the semiconductor pn junction coupling, and then by the semiconductor separation of the negatively charged electrons and holes with positive charged two carriers combined with each other, and produce photons Launch, different types of LEDs can emit light from infrared to blue light, and violet to ultraviolet light of different wavelengths. In recent years, the new development is the blue LED coated with phosphor, the blue LED into white LED products. This operation is generally required with LED Driver or Power Supply. The main function of the drive circuit or power supply is to convert the AC voltage to DC power and at the same time to complete the LED voltage and current To drive the mating components.
