Document Type and Number:
WIPO Patent Application WO/2011/160304
Kind Code:
A1
Abstract:
An LED illumination bulb comprises a lamp head (20), a heat dissipation seat (10), an LED lamp plate (30), and a lampshade (40). The heat dissipation seat (10) is mounted on the upper end of the lamp head (20). The LED lamp plate (30) is mounted on the upper end surface of the heat dissipation seat (10). The lampshade (40) covers the LED lamp plate (30) from outside. The heat dissipation seat (10) comprises a plastic sleeve (11) and heat dissipation fins (12). The heat dissipation fins (12) are fixed outwards on the periphery of the plastic sleeve (11) in a radial array manner. The upper end of each heat dissipation fin (12) is provided with a lap-joint sheet (122). The lap-joint sheets (122) are exposed to the upper end surface of the plastic sleeve (11). The LED lamp plate (30) is arranged on the lap-joint sheets (122). The LED illumination bulb and the heat dissipation seat (10) thereof can reduce the cost, and enhance the insulation performance and the heat dissipation performance.
