Abstract

The invention discloses an LED (Light-emitting Diode) spotlight, which comprises a heat radiation part with a through hole, a connecting plate and a light-emitting module. The heat radiation part is flatly paved on a surface of the connecting plate; the other surface of the connecting plate is connected with the light-emitting module so as to conduct heat produced by the light-emitting module to the heat radiation part; and an outer side face of the heat radiation part is in a zigzag shape. The heat produced by the light-emitting module in the LED spotlight can be firstly conducted to the heatradiation part through the connecting plate, the transferred heat can be then radiated by utilizing the heat radiation part, the heat radiation part is flatly paved on the surface of the connecting plate, the through hole is formed in the heat radiation part, and the outer side face of the heat radiation part is in the zigzag shape, so that air is conveniently circulated, and a heat radiation area between the light-emitting module and air can be increased; and compared with a traditional light-emitting module with multiple heat radiation fins being directly arranged perpendicularly in the LEDspotlight, a heat radiation effect is better, and the heat radiation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of semiconductor lighting, in particular to an LED spotlight. Background technique [0002] Light-emitting diode (LED), as a new solid-state lighting source in the 21st century, occupies a large market share due to its advantages of high photoelectric conversion efficiency, environmental protection and pollution-free, high reliability, fast response time, high radiation efficiency, and long life. Semiconductor lighting technology Realize the rapid development of the third generation lighting. Spotlights are widely used in large-scale performances, sports events, various exhibitions and indoor and outdoor commercial activities. At the same time, because of its narrow light exposure, high light intensity, and easy concentration in a specific area, it is still the most used light for photography. Traditional incandescent lamps and halogen lamps have basically been replaced by LED spotlights due to their high ...
