Title:
LED LAMP HEAT RADIATION STRUCTURE USING MECHANICAL ALLOYING METHOD AND MANUFACTURING METHOD THEREOF
Document Type and Number:
WIPO Patent Application WO/2015/156459
Kind Code:
A1
Abstract:
The present invention relates to an LED lamp heat radiation structure and a manufacturing method thereof and, specifically, to a manufacturing method of an LED lamp heat radiation structure using a mechanical alloying method, wherein the manufacturing method is characterized by comprising: a mechanical alloy powder preparing step of preparing a Cu-Ag alloy powder or Cu-Al alloy powder above thermodynamic solid solubility through a mechanical alloying method; a low-density preliminary molding step of molding the prepared mechanical alloy powder into a pole-shaped preliminary molded body; a high-density molding step of molding the preliminary molded body into a structure of a heat radiation structure; and a deposition coating step of deposition coating diamond like carbon on the heat radiation structure. The heat radiation structure using the Cu-Ag alloy powder or Cu-Al alloy powder prepared through the mechanical alloying method, according to the present invention, is manufactured by subjecting a highly thermal conductive material to plastic processing and deposition coating diamond like carbon thereon, and thus has advantages of having excellent thermal conductivity, reducing manufacturing costs through the minimization of material loss, and preventing environmental contamination.
