Abstract
The present disclosure provides a highly efficient heat dissipation automobile lamp, including: light-emitting units, a base, and a heat dissipation mechanism. An external outline of the base is a frustum, the frustum is provided with an internal heat dissipation cavity, and the light-emitting units are evenly placed around the circumference of the frustum. The heat dissipation mechanism includes a heat dissipater and a heat dissipation rod with one of its ends connecting to the heat dissipater, and the heat dissipation rod is arranged in the heat dissipation cavity. The automobile lamp of the present disclosure achieves high heat dissipation efficiency and uniform light emission in the circumferential direction of the base by arranging the light-emitting units circumferentially along the base and inserting the heat dissipation rod into the heat dissipation cavity, thereby overcoming the problems of poor heat dissipation ability and uneven light emission of LED lamps.
