In the LED integrated light source and its application, LED finished product customer end use for a period of time, are likely to encounter the light does not light (dead light) situation, after the light source product analysis, resulting in dead lights can be divided into the following reasons Species:

Analysis of bad reasons: LED flood light source storage, packaging, welding applications electrostatic damage (human body, environment and equipment and other factors).

Improvement points: ESD protection including storage / operating environment, equipment / equipment grounding, body static protection. Zhihai power technology company requires every employee to wear LED lamps must wear anti-static bracelet, in the assembly process to eliminate static damage to the LED chip.
