An LED bulb comprises a lamp cup, a substrate, a power connecting part, and a cover plate. The lamp cup is a two-piece structure; a power driver is further disposed in the power connecting part. The substrate is disposed in the lamp cup, while the power connecting part connects with the lamp cup. When the light sources and the power structure generate heat, the generated heat can be transferred outwards and dissipated through the lamp cup or the power connecting part. Because the heat generated by both of the heat sources in the lamp cup, respectively, the co-heating effect induced by the light sources and the power driver can be avoided. The overall structure is manufactured by materials having superior thermal conductivity. Thereby, with the structure, heat dissipating process can be accelerated. The lifetime of the light sources can be improved substantially. |
