Title:
METHOD FOR MANUFACTURING CARBON NANOTUBE HEAT DISSIPATION MATERIAL AND LED LUMINAIRE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2020/059929
Kind Code:
A1
Abstract:
The present invention relates to a method for manufacturing a carbon nanotube heat dissipation material and an LED luminaire having same, in which: thermal conductivity, heat release speed, and heat release rate can be significantly increased by replacing the material of a heat sink part and auxiliary heat sinks with a carbon nanotube heat dissipation material instead of the conventional aluminum; heat generated from an LED module can be efficiently dissipated by maximizing a heat dissipation area through a structural change of a frame body and inducing a natural convection phenomenon at the same time; a heat dissipation effect can be maintained for a long time through simple replacement of only the auxiliary heat sinks of the carbon nanotube heat dissipation material without disassembling other parts, by configuring the auxiliary heat sinks to be detachable from the inner surface of the frame body; the uniformity of light can be improved by forming a front diffusion cover into a curved surface; and the heat dissipation effect can be further improved by forming discharge grooves formed inward on the upper surface of the heat sink part and extending to the outer surface of the heat sink part.
