40W LED module

Products feature: 1. Eutectic Technology For LED Many factories use glue (the thermal conductivity is only 5W-20W /mk) to bond chip and package bracket. But we use gold tin solder(the thermal conductivity is 60W /mk)for high power LEDs. It’s only 1°C difference temperature between LED and Metal base. The heat of the chip can be transfered soon and more, in order to be the long lifespan. The design can ensure the high light efficiency (110 120lm/w). 2. Patent Of Heat Sink Our design is the heat sink with air-vent what have already got the patent. The ventilation can enhance the heat dissipation. It’s 3 times better than traditional heat sink.3. Low Light Attenuation We put our 40W module in the 65°C oven temperature. After testing 6000 hrs, we find the LUX only 7.1% lose.4. Our LEDs contrast with Cree LEDs We put our LEDs & Cree & others LEDs in the 85°C oven temperature. After testing 1130 hrs, the light attenuation is almost the same between ours and Cree’s LED. 5.IP 68.
