LED Heat dissipation principle: The heat dissipation to 3 modes: conduction, convection and radiation.
Radiation: the phenomenon that high temperature objects radiate outward directly：
The efficiency of thermal radiation depends on the thermal resistance of the surrounding medium (the surrounding media is often referred to as air) and the characteristics of the thermal radiation itself. But the radiation heat transfer is not so important for the LED lamp, the lamp itself because the temperature is not high, when the temperature is not too high, the phenomenon of radiation is not very strong, so this method considers when the heat dissipation is less.
