HEAT-DISCHARGING APPARATUS FOR LED MODULE AND LED LAMP HAVING THE SAME

PURPOSE: According to the invention, to radiate the heat from a light emitting diode module having at least one light emitting diode (LED) on a substrate, a heat radiation device of an LED module and an LED lighting device including the same comprises a heat absorption block absorbing the heat delivered from the light emitting diode module and fixed to the rear surface of the LED; a heat releasing means connected to the heat absorption block and discharging the heat from the heat absorption block to the outside; a porous metal plate formed between the thermal absorption block, the heat releasing means to transfer the heat from the heat absorption block to the outside, and made of a porous metal; a fixing bracket fixing the porous metal plate to the thermal absorption block. According to the heat radiation device of an LED module and an LED lighting device including the same, the heat dissipation efficiency of the light emitting diode module is improved by extending a heat-exchange surface by bonding the porous metal plate to the thermal absorption block. Particularly, the heat dissipation efficiency is maximized when environment conditions are rather forced convection than natural convection due to the flow of the surrounding air is active like a fish lamp.
