High-efficiency heat radiating LED (light emitting diode) lamp and manufacture method thereof

Abstract

The invention discloses a manufacture method of a high-efficiency heat radiating LED lamp, which comprises the following steps: (1) manufacturing a strip-shaped PCB welding board, and evenly welding a plurality of LED lamps on the PCB welding board, wherein through holes are arranged on the PCB welding board below the LED lamps; (2) manufacturing a strip-shaped graphite radiator by adopting graphite and evenly arranging a plurality of heat conduction rivets on the graphite radiator, wherein the heads of the heat conduction rivets are projected on the graphite radiator, and the space between the two adjacent heat conduction rivets is equal to that between the two adjacent LED lamps on the PCB welding board; and (3) coating heat conduction paste on the upper surface of the graphite radiator and the tops of the heat conduction rivets, and fixing the graphite radiator with the upper surface upward to the lower surface of the PCB welding board, wherein the tops of the heat conduction rivets and the bottoms of the LED lamps are in contact to form a high-efficiency heat radiating structure. The invention also provides the high-efficiency heat radiating LED lamp manufactured by the method.

Description

technical field [0001] The invention relates to an LED lamp, in particular to a method for preparing an LED lamp with high-efficiency heat dissipation and an LED lamp manufactured according to the preparation method. Background technique [0002] Most of the traditional road lamps use high-power mercury lamps, metal halide lamps or high-pressure sodium lamps as light sources. High, lighting effects are unsatisfactory in terms of color rendering and anti-glare performance. At the same time, the development of semiconductor light-emitting diodes (LEDs) is extremely rapid. In recent years, the luminous efficiency of some LEDs has greatly exceeded that of incandescent lamps, and even exceeded that of fluorescent lamps. Compared with the traditional floodlight electric light source, the LED light source is basically non-toxic, non-electromagnetic pollution, and has many advantages such as small size, low energy consumption, high luminous efficiency, relatively low calorific valu...

Problems solved by technology

With the increase of LED power, heat production increases. If the heat dissipation problem is not solved properly, it will accelerate the aging of the device, accelerate the speed of LED light decay, shorten the service life, and even cause burnout; the existing LEDs that use aluminum profiles to dissipate heat The cooling bracket for fluorescent lamps mainly uses a thin-walled circular heat sink. The heat is naturally convected from the round surface of the aluminum material. The circular bracket made according to the required heat dissipation temperature has an unsatisfactory heat dissipation effect and high cost. How to effectively solve the heat dissipation becomes a high-power LED. Lamps face the most pressing problems
