LED when the junction surface temperature increased from 25 ℃ to 100 ℃, its luminous efficiency will decline 20% to 75%, ranging Among them, 75% of the yellow light most serious recession. In addition, when the temperature higher LED operating environment, its production life is lower, people wishing to reduce the LED interface temperature, need to LED packaging production processes, in order to reduce the thermal resistance LED module, the most important thing is cooling substrate material selection and dielectric layer (insulating layer) of the thermal conductivity improvement.
