Efficient-radiation LED lamp and production method thereof

Abstract

The invention discloses an efficient-radiation LED lamp and a production method thereof. The production method includes the steps of firstly, producing a strip-shaped welded PCB (printed circuit board), evenly welding a plurality of LED lamps on the welded PCB, and reserving a through hole on the welded PCB right under each LED lamp; secondly, using graphite to produce a strip-shaped graphite radiator, and evenly disposing a plurality of thermal conducting rivets on the graphite radiator; and thirdly, coating thermal conducting paste on the top surface of the graphite radiator and the top of each thermal conducting rivet, and fixing the top surface of the graphite radiator to the lower surface of the welded PCB, and allowing the top of each thermal conducting rivet to contact with the bottom of each LED lamp to form a efficient radiating structure; wherein, the head of each thermal conducting rivet protrudes out of the graphite radiator, and the distance between two adjacent thermal conducting rivets is identical with the distance between the two adjacent LED lamps on the welded PCB. The invention further provides the efficient-radiation LED lamp produced 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 heat dissipation bracket of fluorescent lamps mainly adopts thin-walled circular heat dissipation, and the heat is naturally convected from the circular surface of aluminum. The circular bracket made according to the required heat dissipation temperature has unsatisfactory heat dissipation and high cost. How to effectively solve heat dissipation and become a high-power LED Lamps face the most pressing problems
