Depends mainly on the life of white LED LED chip quality, led chip design and chip materials. The following factors will affect the life of white LED:
* Good thermal conductivity of the chip
* Chip antistatic properties
* Anti-chip surge voltage and current, etc.
Therefore, in the production of white LED, the LED chip must first understand the performance, but also understand the use of white LED allows the limits of environmental conditions and targets. So as to correct use of white LED, white LED to achieve the best use of time and reliability of the state.
