High-power LED lamp structure and manufacturing method thereof

Abstract

The invention discloses a high power LED lamp structure, including a high power LED illuminator, an aluminum base circuit board used for fixing the high power LED illuminator and a metal lamp case connected with the aluminum base circuit board; the metal lamp case is a cylinder provided with a plurality of radiators at the cirumferential, wherein the aluminum base circuit board and the metal lamp case are connected tightly. The LED lamp uses the section steel shaped by the mould extruding and stretching as the materials to process, then the aluminum base circuit board is extruded into the central hole of the metal lamp case in the interference fit. The invention has the characteristic of simple structure, fast heat emission, low cost etc, which greatly increases the service life of the LED lamp, reduces the temperature round the LED illuminator. The invention is used for the daytoday illuminating with great extending and using value.

[0002] High-power LED lights have been widely used in various fields such as daily life, industry, and commerce. However, the application of high-power LED lights has a common problem, that is, the heat dissipation problem of LED illuminants, and the components of LED illuminants Manufacturers have installed a heat-conducting metal substrate on the bottom of the LED light-emitting chip. LED lamp manufacturers usually fix the LED illuminant on an aluminum-based circuit board, and then connect the aluminum-based circuit board to a metal lamp. The housing is generally connected by screws. In order to achieve a good heat dissipation effect, heat-conducting materials such as silica gel will be applied to the contact parts between the aluminum-based circuit board and the metal lamp housing. Most of the lamp housings are conical structures. The metal lamp housings are die-casting parts. The thickness of the heat sink is reduced, the heat dissipation is poor, and the entire metal lamp housing is large in shape and uses too much material, resulting in high production costs

And because aluminum die-castings are generally used, the process of anodizing the surface of the metal lamp housing is relatively complicated and the cost is high.

If anodizing is not carried out, the surface can only be treated with a very single surface color, and an insulating coating cannot be formed. When it is applied to lighting that uses mains as the power supply, facing various safety certification standards for electrical products, manufacturers The LED lamp products of the company have encountered many difficulties, and the application and promotion of its LED lamp products have encountered insurmountable technical obstacles

[0003] In addition, because the high-power LED lamps in the prior art generally adopt the structure of threaded connection, the installation process is relatively cumbersome, and the processing accuracy of each installation hole also needs to reach a certain degree of accuracy to facilitate the installation of the product, and these to the screw holes Machining and subsequent screw installation add cost
