How to solve the problem of LED lamp heating problem?
Method for solving heat radiation of LED bulb:Solve the LED bulb heat dissipation, mainly from two aspects, before and after encapsulation, can be understood as LED chip heat dissipation and LED bulb cooling.LED chip heat dissipation is mainly related to the choice of substrate and circuit and process, which is not explained here.
The heat of the LED bulb is introduced here, because any LED can be made into a lamp, so the heat generated by the LED chip is always removed into the air through the housing of the lamp. If the heat dissipation is not good, because the heat capacity of the LED chip is very small, the accumulation of a little heat will make the chip's junction temperature rise rapidly. If the long time work in high temperature state, its life will soon shorten. However, these heat can really lead the chips to the outside air and go through many ways.
Specifically, the heat generated by the LED chip comes out of its metal heat sink, first through the solder to the aluminum substrate PCB, and then through the heat conductive glue to the aluminum radiator. Therefore, the LED hotel engineering lamp heat dissipation actually includes the heat conduction and the heat dissipation two parts. However, the size of LED lamp cooling according to power and place, also have different choices.
