    摘要： 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.

    摘要： A lighting fixture includes a light-emitting section composed of a plurality of semiconductor light-emitting devices arranged separated from one another on a planar substrate and a lighting control section configured to control lighting of the semiconductor light-emitting devices of the light-emitting section. The light-emitting section is attached at a front of a fixture main body, and a convection generation section configured to generate convection is provided at a back of the fixture main body. The convection generation section generates convection and promotes heat radiation. With the configuration, even if the lighting fixture is installed to abut on a ceiling surface, the effect of radiating heat generated by the semiconductor light-emitting devices can be ensured.

    摘要： According to one embodiment, a lighting fixture includes a fixture body and a plurality of light-emitting modules. A plurality of light-emitting module arrangement portions are formed on the surface of the fixture body. The light-emitting modules are arranged on the light-emitting module arrangement portions of the fixture body and annularly arranged so that a space is formed at the center area of the fixture body. Semiconductor light-emitting elements are disposed on the surface of the light-emitting module, and a wiring connector is arranged at the space side of the substrate.
