The invention relates to a heat radiator, and in particular relates to a high-power LED (light emitting diode) light source heat radiator, wherein the heat radiator is composed of an upper heat radiation plate and a lower heat radiation plate; the upper heat radiation plate is of an arc shape; two sides of the lower heat radiation plate are provided with vertical brims; the upper edges of the vertical brims at two sides are connected with the upper heat radiation plate; the upper heat radiation plate and the lower heat radiation plate are formed into a through-mouth columnar shape; the upper surfaces of the upper heat radiation plate and the lower heat radiation plate are provided with surging-line-shaped heat radiation fins; the extending direction of the heat radiation fins on the lower heat radiation plate is in accordance with the length direction of the lower heat radiation plate; and the lower surface of the lower heat radiation plate serves as an LED mounting surface. The heat radiator is applied in a high-power LED light fitting, and is especially suitable for LED street lamp fittings. Compared with the similar products, the heat radiation performance of the heat radiator provided by the invention is improved greatly while the production cost is basically unchanged.
Description
technical field [0001] The invention relates to a heat sink, in particular to a high-power LED light source heat sink. Background technique [0002] In recent years, LED has been recognized by the society and widely used due to its energy-saving, high-efficiency, high safety and reliability, and long service life. Especially in recent years, the application of white high-power LED in the lighting industry has made the application of LED The field has advanced further. The development of LED packaging technology is changing with each passing day, but its later application has not reached the ideal application conditions. The reason is that the schemes adopted by the majority of LED lighting manufacturers in the lighting design process are not reasonable enough. Because the LED light source will generate a lot of heat while emitting light, if it cannot be dissipated in time and effectively, the heat accumulated around the LED light source will cause the light source to decay ...
