1、 Aluminum heat dissipation fins
This is the most common heat dissipation method, using aluminum fins as a part of the shell to add heat dissipation area.
2、 Thermal conductive plastic shell
Choosing LED bead insulation heat dissipation plastic instead of aluminum alloy to manufacture heat dissipation bodies can greatly improve thermal radiation ability.
3、 Aerodynamics
Choosing a lamp shell shape to create convective air is the lowest cost method for enhancing heat dissipation.
4、 Liquid bulb
Using liquid bulb packaging techniques, fill transparent liquid with high thermal conductivity into the bulb of the lamp body. This is not only the principle of reflection, but also the skill of using LED bead chips to conduct heat and dissipate heat on the light surface.
5、 Use of lamp caps
When using low-power LED beads at home, it is common to choose the internal space of the lamp holder and place some or all of the heating driving circuit inside. This allows for the selection of lamp holders with larger metal surfaces, such as screw lamp holders, for heat dissipation, as the lamp holders are tightly connected to the metal electrodes of the lamp holder and the power cord. So a portion of the heat can be derived for heat dissipation.
6、 Insulation and heat dissipation plastic replacing aluminum alloy
Insulating heat dissipation plastic replaces aluminum alloy in manufacturing heat dissipation bodies. This type of LED bead insulation heat dissipation plastic can only maintain heat dissipation with aluminum alloy, making the thermal radiation increase by 4-8 times. The LED lamp bead heat dissipation body manufactured using this heat dissipation material can significantly improve the overall heat dissipation effect.
