LED heat dissipation method

Aluminum fins
This is the most common way of cooling, with aluminum cooling fins as part of the shell to increase the heat dissipation area.
Thermal plastic shell
The use of LED insulated thermal plastic instead of aluminum alloy heat sink, can greatly improve the heat radiation capacity.
Surface radiation heat treatment
Light shell surface to do radiation heat treatment, the simple is to apply radiation cooling paint, you can use the heat away from the light shell surface.
Air fluid mechanics
The use of light shell shape, to create convection air, which is the lowest cost to strengthen the cooling method.
fan
Light shell interior with longevity and efficient fan to strengthen the heat, low cost, good effect. But to change the fan is trouble, do not apply to the outdoor, this design is relatively rare.
Heat pipe
The use of heat pipe technology, the heat from the LED chip to the shell cooling fins. In large lamps, such as street lamps are common designs.
Liquid bulb
The use of liquid bulb packaging technology, the higher thermal conductivity of transparent liquid filled into the bulb bulb. This is in addition to the principle of reflective, the only use of LED chip out of the smooth heat, heat technology.
The use of the lamp
In the home-type smaller power LED lights, often use the lamp inside the space, the heating of the drive circuit part or all into. This can be used like a screw cap so that there is a large metal surface of the lamp cooling, because the lamp is close to the lamp holder metal electrode and power cord. So a part of the heat can be derived from the heat.
Integration of Heat and Heat Dissipation - Application of High Thermal Conductivity Ceramics
The purpose of cooling the lamp shell is to reduce the LED chip operating temperature, due to the expansion coefficient of LED chips and our commonly used metal thermal conductivity, thermal expansion coefficient of the gap is very large, can not be directly welded LED chip to avoid high and low temperature thermal stress LED chip. The latest high thermal conductivity ceramic materials, thermal conductivity close to aluminum, expansion can be adjusted to synchronize with the LED chip. So that you can heat, heat integration, reduce the heat conduction intermediate links.
