Abstract
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.
