Abstract

The invention discloses a heat radiation device, which comprises an LED (light emitting diode), a copper aluminum base plate and a heat radiator, wherein the copper aluminum base plate is used for carrying and installing the LED, the heat radiator is arranged under the copper aluminum base plate and comprises an annular base and an axis post arranged in the base, the top surface of the base upwards extends for forming a plurality of heat radiation fins, the heat radiation fins are in outer flow line type arc shapes, and in addition, gaps are formed among the heat radiation fins. The base formed by a plurality of circularly surrounding heat radiation fins in the outer flow line type arc shapes is adopted, the heat radiation area of the heat radiation device is greatly enlarged, in addition, the axis post simultaneously has the heat radiation effect, the heat radiation efficiency is high, the evanescence of the LED lamp is delayed, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of LED lighting, in particular to a heat dissipation device for an LED lamp with good heat dissipation efficiency. Background technique [0002] With the in-depth application of high-power LED lights, a technical bottleneck has arisen, that is, light decay, that is, the heat dissipation problem of LED lights. The existing heat dissipation method is mainly to transfer the heat generated by the LED to the heat sink through the copper-aluminum substrate. On the radiator, the heat is dissipated into the air by the radiator. In the existing heat sink, its surface is made into a fin shape, and the fins are distributed in parallel to increase the heat dissipation area of ​​the heat sink and improve the heat dissipation efficiency, but the heat dissipation area has not been maximized, and only by relying on It is very limited to increase the heat dissipation area to improve the heat dissipation efficiency, and its ...
