LED lighting as a rising star in the field of lighting, considerable market prospects in the next five years, and to show strong growth momentum. The LED lighting fixture according to continuously reduce the price, and improve performance trends, the overall cost of whole life cycle of the LED lamps in the vast majority of future 1-- significantly lower than conventional lamps 2 years, mainstream lighting.
LED lamps as the shell, will be aluminum, ceramic material, conventionally, while the last two years, the sudden emergence of new thermally conductive plastic material, the majority of manufacturers is gradually accepted as shell material much attention.
To sum up, the thermally conductive plastic has several advantages:
1, fire-retardant insulation, high reliability;
2, light weight, a density of about two-thirds of the aluminum material;
3, to facilitate molding process, good mass productivity;
4, no secondary processing, greener.
The face of numerous heat-conducting plastics suppliers , how to choose a more reasonable cost-effective products, the following are some of the points of concern:
1, the thermally conductive plastic RoHS, UL certification;
2, the material required for processing equipment;
3, the color material;
4, production of the raw materials.
Comparison of material properties:
1, the thermal conductivity;
2, flowability of the material;
3, the mold shrinkage factor;
4, the mechanical properties;
5, flame retardant properties;
6, an insulating property;
7, the thermal expansion coefficient.
