Embodiment Construction

[0018] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0019] A method for manufacturing a radiator for LED lamps, characterized in that it comprises the following steps:

[0020] Modified resin with thermal conductivity not less than 0.9 and powder with normal emissivity not less than 0.89 are prepared into coatings and electrophoretic materials. The modified resin includes modified epoxy, silicon, polyimide, and diphenylene ether resins, and the powder includes carbon nanotubes, silicon carbide, and zirconia.

[0021] Plasma treatment is performed on the heat sink of the LED lamp, and then the prepared coating and electrophoretic material are prepared on the surface of the heat sink of the LED lamp by means of spraying, dipping, electrophoresis, chemical vapor deposition (Chemical Vapor Deposition, CVD for short) and the like.

[0022] Under the same test conditions, the heat d...

Abstract

The invention discloses a method for manufacturing an LED lamp radiator, which comprises the following steps: modified resin with thermal coefficient of not less than 0.9 and powder with normal radiance of not less than 0.89 are prepared into a paint and an electrophoresis material; the LED lamp radiator is subjected to plasma treatment; and the prepared paint and the prepared electrophoresis material are arranged on the surface of a radiating fin of the LED lamp radiator through spraying, dipping, electrophoresis, chemical vapor deposition and other modes. Under the same testing condition, the radiating capacity is promoted by 10 to 12 percent compared with the anode oxidation treatment and is promoted by 5 to 7 percent compared with the block coloration treatment. Because of the promotion of the radiating capacity, the weight of an LED lamp shell (the radiator) can be manufactured to be lighter under the condition of unchanged radiating capacity. The LED lamp radiator manufactured by the method has the obvious advantages of high radiating efficiency, energy conservation, light weight, reliable performance and the like.

Description

technical field [0001] The invention relates to a method for manufacturing a light emitting diode (Light Emitting Diode, LED for short) lamp radiator. Background technique [0002] LED lamp radiators are basically made of aluminum alloy. At present, the surface treatment of LED lamp radiators usually includes: anodizing treatment and blackening treatment. However, these two methods do not improve the heat dissipation capability of the LED lamp radiator much, and the heat dissipation capability of the LED lamp radiator is still very poor. Contents of the invention [0003] The technical problem to be solved by the present invention is to propose a method for manufacturing a heat sink for LED lamps with good heat dissipation capability and low cost in order to overcome the above disadvantages. [0004] Technical problem of the present invention is solved by following technical scheme: [0005] A method for manufacturing a heat sink for an LED lamp, comprising the following...
