Cooling device manufacturing method, cooling device and lighting device

Abstract

The invention relates to a cooling device (100) manufacturing method. The method includes the steps: a) providing a base (1) made of metal by the aid of a forging process; b) providing at least one cooling part (2); c) fixing the cooling parts (2) to the base (1). In addition, the invention further relates to a cooling device (100) manufactured by the method and a lighting device (200) with the cooling device (100).

Description

technical field [0001] The invention relates to a method of manufacturing a heat sink. In addition, the present invention also relates to a heat dissipation device manufactured by the above method and an illuminating device with the heat dissipation device. Background technique [0002] LED replacement lamps such as types like MR16, PAR38, A60 and GX53 are increasingly replacing traditional lighting fixtures such as incandescent and fluorescent lamps. This is because replacement lamps of this type are more energy efficient, smaller in size and have a longer life. With the development of technology, the LED package itself can achieve higher efficiency, for example, it can obtain 140lm / W cool white light and 90lm / W warm white light, and its life span can reach 50,000 hours. But when LEDs are integrated into replacement lamps along with LED drivers, thermal management devices, and optics, the efficiency and lifetime of the replacement lamps are highly dependent on how the dri...

Problems solved by technology

However, there may be gaps in the material of the cast heat sink, which greatly increases the thermal resistance of the heat sink and reduces the heat dissipation performance of the heat sink

The cost of the ceramic radiator is too high, and at the same time, due to the fragile characteristics of the ceramic material, it is easy to cause damage to the radiator
