silica (1.3-1.4) than the epoxy resin (1.5 or above) is low, so the epoxy is less than the initial high light efficiency.
Fifth, support the white LED light decline of
LED stent mainly copper and iron bracket bracket. Thermal conductivity of copper bracket, conductive performance, high price. The iron frame of the thermal conductivity, electrical conductivity is relatively poor, more likely to rust, but the price is cheap. Most LED on the market use of iron bracket.
