Shenzhen Hua Kai Electronics Co., Ltd.1?Using self-developed cooling technology, ?LTS? brazing technology. Achieve a close connection with the light source and the heat sink, the thermal conductivity of LTS is 40 times more than traditional thermal grease. Closely connect the light source with the heat sink. The temperature at the bottom of the LED board is higher than the heat sink only less than 1?. The temperature difference between the thermal silica is least 5?, more effectively guarantee the effective life of the LED chip.
