This is in addition to the reflective principle, the only use of LED chip smooth surface heat conduction, heat dissipation technology. The use of the lamp cap, in the household type of small power LED lamp, often use the internal space of the lamp cap, will heat the drive circuit part or all of the place. This allows the use of a cap with a large metal surface, such as a screw cap, to dissipate heat because the cap is tightly connected to the metal electrode and power cord, so some of the heat can be derived from this.
