HEAT SYSTEM OF LED LIGHTING APPARATUS

摘要

PURPOSE: By using the heat pipe carrying the high coefficient of heat conduction, the cooling system of LED lighting device rapidly transfers the heat of the lighting device inside to outside. CONSTITUTION: A plurality of LEDs(20) is mounted in the printed circuit board(10). One end of LED is connected to the heat radiation fin(30). The heat pipe(40) emits the heat metastasizing from LED to the heat radiation fin to outside. The cooling water pipe(50) cools the heat metastasizing from LED to the heat pipe.
