Abstract
The invention relates to an LED (Light Emitting Diode) spotlight for heat loss through convection by air, which comprises a radiator and an optical engine. The radiator comprises a cylindrical shell opened at both ends and connected as a cavity and a radiating piece in the cavity of the cylindrical shell. The optical engine comprises a front cover, an aluminum base plate, a plurality of lenses arranged between the front cover and the aluminum base plate, and a plurality of LEDs. After assembly, external air is communicated with the cavity in the front cover through a ventilating through groove. The aluminum base plate is fixedly connected at the central position of a heat conductive connecting part on the radiator through a bolt. The section of the aluminum base plate is smaller than that of the cavity of the radiator so that the cavity in the front cover is communicated with lower openings of vertical convection cavities independently arranged through gaps in the periphery of the aluminum base plate, and the upper openings of the vertical convection cavities independently arranged are communicated with external air. With the adoption of the structure, the LED spotlight radiates in vertical convection by air, is fewer in structural components, easy to assemble and convenient to extend and expand products, and low in cost.
