LED light fixture with LED heat dissipation structure and corresponding heat dissipation structure

摘要

A heat dissipation structure of a kind wherein a gap between the pins 12 constitutes a plurality of continuous air channels 16 and the exhaust end of the air channel 16 extends to the peripheral side of the radiator 1 A radiator (1) provided with a radiator (12); An air inlet cavity 71 is formed to cover the opening of the air channel 16 located at the end of the pin 12 and partially open to communicate with the air channel 16, A cover plate (7); And an air blowing device 72 for forcedly blowing air into the air inlet cavity 71. The opening of the air channel 16 located at the end of the pin 12 is closed and the air inlet cavity 71 is provided in a part of the center of the cover plate 7 by covering the cover 12 with the cover plate 7 , The cooling air is forcedly blown into the air channel 16 through the air blowing device 72 to improve the heat exchange area and efficiency and satisfy the demand of the high output LED lamp.
