Patent ID: 8197086

Claim:
A lighting fixture comprising: a light-emitting section composed of a plurality of semiconductor light-emitting devices arranged separated from one another on a planar substrate; a lighting control section configured to control lighting of the semiconductor light-emitting devices of the light-emitting section; a fixture main body in which the light-emitting section is attached at a front; and a convection generation section configured to generate convection at a back of the fixture main body, wherein the convection generation section is composed of a plurality of fins provided at the back of the fixture main body; and the plurality of fins is configured such that fin heights of the fins increase toward the light-emitting section, wherein the lighting fixture further comprises an attachment provided at a distal end of a one of the fins which has a largest height and is configured to attach the fixture main body to a ceiling surface, wherein the convection generation section generates an airflow by means of a thermal gradient caused by a difference in height between the plurality of fins in a space between the back and the ceiling surface.
