Abstract:
Disclosed is a lighting device. The lighting device according to the present invention comprises: a first lamp; and a reflector having a reflecting surface for reflecting light emitted from the first lamp. The reflecting surface comprises: a first reflecting surface concave toward the first lamp; and a second reflecting surface which is positioned on the opposite side of the first reflecting surface with respect to the first lamp and is convex toward the first lamp, wherein the further from the first lamp, the wider the distance between the first reflecting surface and the second reflecting surface becomes. Due to forming the first reflecting surface and the second reflecting surface in the reflector and forming the distance between the first reflecting surface and the second reflecting surface to become wider the further from the lamp, the present invention can easily form light distribution (batwing) by the reflector, in particular in terms of roadway lighting, can form light distribution expanded in the direction of a moving path of a vehicle, and can implement various types of light distribution by adjusting the movement of a pressurizing unit and the first lamp.
