ProLight, a Taiwan high power LED packaging house, introduced the latest E series products which can be driven to higher drive current. E series adopts ProLight’s patented High Thermal Eutectic Technology. The eutectic material that is commonly used is Au-Sn, the thermal conductivity is around 58W/mK, but ProLight have developed the high thermal dissipating eutectic material, which have thermal conductivity over 160W/mK. This unique eutectic can reduce heat resistance and drive LED by higher current to optimize lumens.
