Patent ID: 8480263

Claim:
A heat dissipation structure for lighting device, comprising: a base, which has an end forming an electrical connector section and an opposite end forming an open cavity; a light emission module, which comprises a substrate and a plurality of light emission elements, the substrate being mounted in the open cavity of the base, the light emission elements being mounted on a surface of the substrate; a heat dissipation module, which comprises a plurality of heat dissipation plates, the heat dissipation plates being arranged in a stacked manner on an opposite surface of the substrate and located inside the base, whereby the heat dissipation module forms a concentrated heat dissipation zone with the heat dissipation plates, each of the heat dissipation plates having a circumference along which a plurality of inclined side wing sections is circumferentially distributed, two adjacent ones of the side wing sections of each heat dissipation plate forming a first heat dissipation gap therebetween, the side wing sections of an upper one of the stacked heat dissipation plates and the side wing sections of a lower one of the stacked heat dissipation plates being of different inclination angles, a second heat dissipation gap being formed between the side wing sections of the adjacent upper and lower ones of the stacked heat dissipation plates, an expanded heat dissipation zone being formed with the side wing sections that are provided on a perimeter of the heat dissipation module; and a control circuit module, which is received in the base, two ends of the control circuit module being respectively in electrical connection with the substrate and the electrical connector section.
