1. A basic overview of the industry

LED lighting that is light-emitting diode lighting, is a semiconductor solid light-emitting devices, is the use of solid semiconductor chips as light-emitting materials, in the semiconductor through the carriers occurring composite release of excess energy and cause photon emission, directly emit red, yellow, blue, green light, on the basis of the use of the principle of the three primary colors, add phosphor, you can emit any color of light.

LED lighting according to different luminous intensity, can be divided into ordinary brightness LED, high brightness LED, ultra-high brightness LED, which ordinary brightness LED is mainly used to do all kinds of instrumentation indicators, or small characters, digital displays, etc.; high brightness LED is used in the field of special lighting, such as full-color displays, automotive lamps, special work lighting, military field, etc.; ultra-high brightness LED is widely used in civil, industrial lighting and other types of general-purpose lighting. In civil, industrial lighting and other types of general lighting field.
