PURPOSE: A light emitting diode lamp is provided to maximize the thermal performance by plane contact of supporting plate with the heat dissipation main body. CONSTITUTION: The lamp base(100) of cylindrical comprises the battery supply circuit for the power source being provided from the socket binding site(110) and outside and supplying to drive to the necessary power source. The large diameter part(210) is accepted to the bottom part of the lamp base. The large diameter part and bottom plane(211) center of the heat dissipation main body(200), diameter is reduced. The heat radiation fin(310) defines the lower direction heroine expanded from the bottom side. The heat radiation fin is formed according to the exterior wall of the heat dissipation main body into the equal space. |
