HEAT-DISCHARGING APPARATUS FOR ILLUMINATOR USING LED

摘要

PURPOSE: A heat discharging device for a lighting unit using an LED is provided to obtain high heat discharge effect without an auxiliary device or additional power by adopting a natural convection method. CONSTITUTION: An LED module(10) is fixed in one side of a body(110). The body has a sealed inner space. A heat transfer unit(120) is arranged in the body adjacent to the rear of the LED module. The heat transfer unit receives the heat from the LED module and has the L shape. A refrigerant(130) is filled in the sealed inner space of the body and receives the heat from the heat transfer unit. A circulation induction part(140) induces the circulation convection of the refrigerant. A plurality of cooling pins(150) are formed in the outer surface of the body and discharge the heat from the refrigerant to the outside.
