However, heat dissipation of led light shell according to the power size and use of the site, there will be different options. Now there are mainly the following methods of cooling: aluminum fins: This is the most common way of cooling, with aluminum fins as a part of the shell to increase the heat dissipation area.
Thermal conductive plastic shell: fill the plastic shell when injection molding material, increase the thermal conductivity of plastic shell, heat dissipation capacity.
Air hydrodynamics: Air hydrodynamics uses the shape of the lamp shell to create a convective air, which is the lowest cost of the enhanced heat dissipation method. Fan lamp housing with longevity and efficient fan to enhance heat dissipation: low cost, good effect.
But to change the fan is troublesome, also not suitable for outdoor, this design is relatively rare. Heat conduction heat pipe cooling technology: The heat pipe is used to guide heat pipe technology, the thermal led chip to the shell fins. In large led flood light, such as streetlights, this is a common design. Surface Radiation heat Treatment lamp shell surface to do radiation heat treatment: the simple is to smear radiation thermal paint, you can radiate heat from the surface of the lamp shell.
