The present invention concerns a fan-less heat ventilation for an LED-lighting apparatus and it comprises a heat radiation frame which is distanced from the circumference of a main body and linear heat radiation pins which maximizes air flow and heat radiation area. Accordingly, the heat radiation area is remarkably enlarged and the whole enlarged heat radiation area is easily available so heat ventilation performance is considerably improved, enabling rapid and efficient heat radiation without a blowing fan. Consequently, the lifetime is extended and quality is improved. The disclosed LED lighting apparatus comprises: a light source which includes one or more LED (Light Emitting Diode) and PCB (Printed Circuit Board) with LED; a heat radiation housing which houses and supports the light source, and emits heat, and wherein a terminal member is equipped on the top thereof. The heat radiation housing comprises a main body in which a light source installation unit and a power control unit are placed, a ring-shaped heat radiation frame which is distanced from the outer circumference of the main body and plural linear heat radiation pins which are placed at a certain interval to connect the main body and the heat radiation frame, and emit heat as well. The light source installation unit faces downward and toward the light source and the power control unit is placed thereon. |
