The led light cup is the best
It is difficult to pass the test certification of high pressure in the use of non-blocking power sources. Although ceramic materials have excellent thermal conductivity and insulation resistance, it is difficult to process, and it is also a bad aspect. The insulating properties of conductive plastic, which have certain advantages in high pressure testing,
The thermal conductive plastic has the characteristics of uniform cooling, light weight, high safety factor and flexible design. Compared with ceramic, the thermal plastic is strong, the forming process is convenient, the design freedom is higher. The expansion coefficient of conductive plastic is higher than that of ordinary plastic.
Led lamp cup material should first consider the conduction characteristic of material, next is the appearance of whole. According to the knowledge, the current conventional lamp cup-shell heat dissipation material consists of the following three kinds: metal material, ceramic and general plastic. The lamp cup of metallic material is hot, easy to process, modelling is diverse, but because of its high conductivity
