HEAT DISSIPATING UNIT AND LED LIGHTING APPARATUS USING THE SAME

摘要

The present invention relates to a heat dissipating unit and an LED lighting apparatus using the same, wherein the heat dissipating unit can be manufactured by a simple manufacturing process and with reduced manufacturing costs, and which discharges heat in an effective manner when arranging a driving element on the rear surface of an LED substrate on which a plurality of high luminance LEDs are mounted. The heat dissipating unit is configured in that heat dissipating fins are arranged inside and outside of a hollow body, and openings are formed at the hollow body to effectively dissipate heat to the outside via both conduction and convection. The heat dissipating unit for the LED lighting apparatus includes a truncated cone-shaped or cylindrical main body having a hollow portion, and heat dissipating fins arranged into a spire along the outside and/or the surface of the main body. Moreover, the main body further includes a plurality of openings penetrating through the main body to enable air convection.
