Saving cost for LED light

LED chips occupy the major part of the cost of the LED, thus reducing the cost of the main route LED is to reduce the cost of the LED chip. Even for led light manufacture China, we need to save cost for LED light.

 

The key LED chip technology development lie in the base material and epitaxial growth techniques. The base material by the traditional materials of sapphire, silicon and silicon carbide, the development of zinc oxide, gallium nitride, and other new material for cheap and practical led flood light. In just a few years, by means of a series of technical improvements, including chip architecture, surface roughening treatment and multiple quantum well structure including design, LED light effect in achieving a tremendous breakthrough.

 

Low cost silicon substrate technology continue to progress, but the luminous efficiency are still not satisfied that if they keep this pace in led panel light wholesale.
