WIPO Patent Application WO/2017/095181
Kind Code:
A1
Abstract:
Disclosed is an LED lighting device wherein the heat sink is made of a composite material, and an area, which corresponds to the LED module, is formed using a material having a higher thermal conductivity than that of the composite material such that, compared with a heat sink made of aluminum, the same is less expensive and lighter, and secures an equal or better heat-radiating performance. The disclosed LED lighting device comprises: an LED module having a plurality of LED elements mounted on one surface thereof; a heat sink coupled to the other surface of the LED module; and an auxiliary heat-radiating substrate, which is inserted into the heat sink, and one end of which contacts the other surface of the LED module, wherein the auxiliary heat-radiating substrate has a higher thermal conductivity than that of the heat sink.
