Title:
HEAT-DISSIPATING STRUCTURE OF AN LED ILLUMINATING DEVICE, USING A HEAT PIPE MODULE
Document Type and Number:
WIPO Patent Application WO/2011/155783
Kind Code:
A1
Abstract:
The present invention relates to a heat-dissipating structure of an LED illuminating device. The heat dissipating structure of the present invention comprises: a substrate including a circuit pattern and at least one through portion; at least one LED light source module which is mounted on one surface of the substrate, and which has an upper portion arranged across the through portion of the substrate; a heat block which has a recessed groove-shaped or through hole-shaped joint portion, and at least a portion of which is inserted into the through portion of the substrate to be brought into contact with the LED light source module, and which has an alumina(Al2O3) layer for electrical insulation, formed in the portion contacting at least each LED light source module, wherein the alumina layer is formed by anodizing; a heat pipe a portion of which is inserted into the joint portion of the heat block; and a heat-dissipating fin coupled to the heat pipe. According to the present invention, heat generated from the LED light source module is directly transferred to the heat block, thereby significantly improving heat-dissipating efficiency of the LED illuminating device. In addition, the necessity of using expensive metal substrates for heat-dissipation is eliminated, thereby remarkably reducing production costs for LED illuminating devices as compared with conventional devices. In addition, an LED light source module can be mounted on a general PCB other than those made of metal materials, and therefore, the LED light source module and circuit components required for operation can be mounted all together on the same substrate, thereby simplifying manufacturing processes.
