Heat dissipating structure for light bulb

Abstract

The present invention provides a heat dissipating structure for a light bulb and enhances the heat dissipating efficiency of the light bulb. The heat dissipating structure comprises a heat dissipating housing and a plurality of fins. The light source is assembled on the plurality of fins. The heat generated by the light source is conducted to the heat dissipating housing via the plurality of fins. In addition, a power driver is disposed at the bottom of the plurality of fins and dissipates heat through the heat dissipating housing. Thereby, the light source and the power driver, which are two heat sources, are disposed separately. Then the heat is transferred to the surrounding environment by means of the heat dissipating housing. Consequently, the overall heat dissipating process is accelerated, thus improving the light emitting efficiency and lifetime of the light bulb.
