PURPOSE: An air ventilation led lighting device with an improved heat dissipation function is provided to improve the stability of a product by maximizing the heat dissipation and cooling efficiency. CONSTITUTION: A plurality of LEDs is installed in an LED substrate(110). The LED substrate is placed along the outer surface of an air ventilation radiating unit(120). The air ventilation radiating unit rapidly absorbs and releases conductive heat generated from the LED substrate. The air ventilation radiating unit comprises an air ventilation through-hole(121) and multiple concavo-convex portions(122). A transparent cap(130) is made of transparent or translucent materials transmitting the light. A reflector(140) comprises an inner side made of a light-reflecting material in order to irradiate LED light in the specific direction. The transparent cap blocks the opened side of the reflector. |
