Abstract: The purpose of the present invention is to provide an unsymmetrical light distributing reflector for a wall washer, which has an improved structure for distributing or focusing light to a desired part of a wall and an improved luminous efficacy, and a lighting device using the same. The unsymmetrical light distributing reflector is installed inside the lighting device, and has a circular truncated cone shape with light transmitting parts formed at the top and the bottom, wherein a first light transmitting part of the light transmitting parts is formed at the top of the reflector to have a circular arc shape, and a second light transmitting part of the light transmitting parts is formed at the bottom of the reflector to have an oval or a water drop shape. According to the present invention, it is possible to evenly distribute or focus light to a desired work surface of a wall by improving the structure of a reflector, whereby luminous efficacy of a lighting device is enhanced.
