Has been widely used in traffic lights, automotive lighting, billboard lighting and other special fields, and gradually transition to the general lighting field, is recognized as expected to replace incandescent, fluorescent fourth-generation light sources. LED lighting has energy saving, environmental protection, high efficiency, long life and so on excellent performance, good prospects for development, attention and trust. LED since launch, we received a lot of attention from all sectors, especially indoor lighting, office lighting. LED lamp, LED bulb, LED Grille and other common lighting, the lighting is open to all fields of application.

 

  LED lighting for many areas, different applications of the LED light source, higher demands, in addition to the optical efficiency of the LED, the light color have different requirements, but also for the light angle, light intensity distribution have different requirements. This not only requires the development of new plant upstream chip semiconductor materials, improve chip production process, designed to meet the requirements of the chip, but also put forward higher requirements downstream packaging plant, designed to meet a certain intensity of the package structure, improve the external LED light use rate.
