PURPOSE: An apparatus for radiating heat of LED lamp is provided to improve the thermal performance and cooling effect by using temperature difference. CONSTITUTION: In the front surface of the cylindrical housing(1), the transparent lens(2) is installed. In the back side of the cylindrical housing, the perforated plate(3) is installed. The circuit board(5) arraying a plurality of LED chips(4) on circular is installed in the inner side of the housing. The aluminum material cooling fin(6) is installed in the housing backside surface. The inner tub pore consisting of the heat discharge hole in the circuit board and outside suction hole is formed into the circular array. In the cooling fin, a plurality of inductive groove(10) is formed into the radial shape arrangement in order to accord with each inner tub pore location of the circuit board. The outside breather consisting of the outside suction hole on the top of the inductive groove and heat discharge hole is formed. The inside hot air is emitted through the heat discharge hole to outside. |
