Title:
LED LIGHT MODULE COMPRISING HEAT SINK USING CARBONACEOUS MATERIAL
Document Type and Number:
WIPO Patent Application WO/2022/260194
Kind Code:
A1
Abstract:
The present invention relates to an LED light module comprising: an LED module driving a plurality of LEDs; and a heat sink coupled to the LED module. The heat sink comprises: a base part on which the LED module may be mounted; and a plurality of heat dissipating horns protruding on the top surface of the base part. The heat dissipating horns: comprise a carbonaceous material or a carbon composite material; and are in a hollow cylindrical shape of which the area of the internal cross section gradually increases in the direction away from the base part which is an attached surface. According to the LED light module comprising the heat sink using a carbonaceous material of the present invention, the LED light module has enhanced heat dissipation performance and corrosion resistance, and the weight of the LED light module may be reduced.
