With the gradual development of LED Lights, led high bay has replaced some traditional lighting products in lighting projects of public places. It is a dark horse in lighting industry indeed, but there are still technology problems that are to be solved:1. Heat dissipation problemAs with traditional chips, LED chips can also generate heat during operation. The heat volume is dependent on the light efficiency of the light. Under the effect of electricity power, the radiate compound of electron and hole can produce light, and then the radiated light near PN would need semiconductor media and encapsulation media of the chip to reach the outer space (air).
