PURPOSE: A reflective lighting device is provided to easily remove a dark part under a lighting device by forming a reflector with dual curved surfaces on the upper side of an LED source with a narrow diffusion angle. CONSTITUTION: A light emitting unit(100) radiates light. A reflector(200) is positioned on the upper side of the light emitting unit. The reflector reflects light radiated from the light emitting unit. A heat sink(300) includes a plurality of heat radiation fins(310,320). A plurality of heat radiation fins are arranged in parallel. |
