LED
The main heat source:
The heating place of the lamp mainly stems from the bead.
The heating of the LED itself is the energy conversion of PN junction
The heat dissipation principle:
Thermal pad is used between LED aluminium plate and the shell to transfer the tempreature of LED bulbs rapidly to the radiator or the metal shell by thermal conductive principle. The heat gets removed by the heat dissipation principle of air convection. The temperature of the heated component gets lowered to extend the life span.
