Disclosed is a heat-dissipating device using an LED for a headlight. The disclosed heat-dissipating device using an LED for a headlight is for dissipating heat generated from a headlight having an LED module and comprises: a body including an LED module affixed to the upper surface thereof and a multiplicity of cooling pins arranged in a spiral form on the outer periphery thereof, the body having a tapered cross section in a downward direction; and a suction air guide surrounding the outside of the body, the air guide having a multiplicity of pores for air suction. The heat-dissipating device using an LED for a headlight is advantageous in that the suction air guide may be arranged in various forms depending on the contour of a vehicle, and that the heat-dissipating structure ensures more efficient heat emission when a vehicle is in a drive mode as well as in an idle stop mode. Moreover, by adopting a simple structure for generating a suction air cyclone without using an additional power supply, the heat-dissipating device can have a high-efficiency heat emission effect and in particular, a high energy-saving effect. |
