PURPOSE: A circulation type heat sink for a lighting device is provided to lower the temperature of a heat radiation plate by rapidly cooling the heat of the heat radiation plate using fluid circulation in a heat collector. CONSTITUTION: A circular fixing plate(110) is formed on the lower side of a lighting(120). A lighting unit(100) includes a heat radiation plate(130) with a heat collector inserting groove. A temperature sensor(40) is formed on the side of a heat collector(140) to check the temperature of the lighting. A circulation unit(200) moves heat of the heat radiation plate through fluid of a circulation pipe. A cooling unit(300) cools the fluid of the circulation unit. A binding member(30) connects an input pipe and an output pipe. |
