  • Publication number: 20100124064
    Abstract: A lighting device includes a light source configured to radiate light toward a floor from a ceiling, a reflecting mirror provided around the light source, and shading angle setting element configured to define a range in which the light from the light source is radiated by setting a shading angle with respect to the light radiated from the light source. The light source, the reflecting mirror and the shading angle setting element are covered by a translucent cover. The translucent cover has an in-line transmittance. An in-line transmittance of the translucent cover of a position corresponding to an optical axis of the light source and an in-line transmittance of the translucent cover of a position deviated from the optical axis are different from each other.

  • Publication number: 20100079087
    Abstract: The present invention comprises a lighting apparatus main body having a reflecting surface, a main light source arranged in the reflecting surface of the lighting apparatus main body, a sub-light source which is arranged at the lighting apparatus main body and illuminates the neighborhood of the main light source directly, and a control circuit which controls the main light source and the sub-light source. Since the lighting apparatus illuminates downward with a direct illumination of the main light source and an indirect illumination of the sub-light source, the glare of the main light source is reduced.
