LED lighting life affect many factors in addition to the most common adverse heat outside, according to the experience of the application of death caused by lamps or LED highbay light failure, the cause of discoloration due to the manufacturing process there is chemical pollution caused by:
For applications downstream end, in addition to the appropriate cooling solution, the other in the lamp assembly process, the manufacturing process or chemical additives are required to avoid the so-called chemical incompatibility, LED lighting fixtures are not compatible with volatile organic compounds, can quickly damage any manufacturer of the LED. This chemical substance is not compatible with a local phenomenon often occurs at elevated temperatures, and having little or no air flow seal lamps.
LED packaging factory after tests found some of the known LED can easily affect the normal function of the chemical, the client is best to establish a comprehensive chemical testing and evaluation systems are not compatible. With proper precautions, design and testing, the impact can be minimized or until eliminated. The adverse effects of chemical incompatibilities most obvious is blue, dark blue light white LED, rarely observed in red or green LED.
Designers should take full account of minimizing the impact of chemical substances between (mainly a LED optical lens Molding gum and in electronic assembly and lamps used in various chemicals), mix together because these items may damage LED highbay light output efficiency, or even cause permanent failure LED occurring phenomena (such as dead lights, color, dark, light, etc.). Because the chemical incompatibilities and high temperatures cause the LED package LED failure result is the same: the flux decay, color temperature drift and so on.
