solve the heat dissipation of LED bulbs, it is necessary  start with two aspects before and after packaging. It can also be undersod as LED chip heat dissipation and LED bulb heat dissipation.

　　The heat dissipation method of the LED chip is mainly related  the choice of substrate and circuit and the process. Any LED can be made in a lamp, and the heat generated by the LED chip will eventually be dissipated in the air through the lamp housing. Because the heat capacity of the LED chip is relatively small, a small amount of heat accumulation can quickly increase the junction temperature of the chip. If it is operated at a high temperature for a long time, its life will be shortened quickly. However, there are many ways for this heat  actually guide the chip  the outside air. Specifically, the heat generated by the LED chip comes out of its metal heat sink, passes through the solder  the PCB of the aluminum substrate, and then reaches the aluminum radiar through the thermally conductive glue. Therefore, the heat dissipation of LED lamps actually consists of two parts: heat conduction and heat dissipation. The heat dissipation of the LED lamp housing also needs  consider different options according  the power size and the place of use.

　　Here are some common heat dissipation methods for LED lights:

　　1. Aluminum fins

　　This is the most commonly used heat dissipation material, and aluminum heat dissipation fins are used as the shell  increase the heat dissipation area. The LED wer chandelier of our company uses fins as the heat-conducting material.

　　2. Thermally conductive plastic shell

　　Fill the plastic shell with heat-conducting material during injection molding  increase the heat conduction and heat dissipation capabilities of the plastic shell.

　　3. Air fluid mechanics heat dissipation

　　Aerodynamics uses the shape of the lamp housing  create convective air, which is the lowest cost way  enhance heat dissipation.

　　4. Long-life and high-efficiency fans are used inside the fan lamp housing  enhance heat dissipation

　　The cost is low and the effect is good. However, it is more troublesome  change the fan, and it is not suitable for outdoor use. This kind of design is relatively rare.

　　5. Heat pipe heat dissipation

　　The heat pipe uses heat pipe technology  conduct heat from the LED chip  the heat dissipation fins of the housing. In large lamps, such as street lamps, this is the design.

　　6. Surface radiation heat dissipation treatment The surface of the lamp housing is treated with radiation heat dissipation
