PURPOSE: A heat dissipation system of a light emitting device is provided to drive a cooling fan by using air convection caused by heat generated from a light emitting device. CONSTITUTION: One or more light sources(100) are mounted on a substrate(200). An electrode pattern is formed to connect an adopter and the light source. The light source is arranged at a lower surface of the substrate. A heat sink(300) is arranged on an upper side of the substrate in order to emit heat generated from the light source. The heat sink is composed of a plurality of heat radiation fins having a constant interval. A radiating unit is arranged to be opposite to the heat sink. A cooling fan(400) is rotated through air convection caused by heat generated from the heat sink. |
