LIGHTING APPARATUS, LIGHT SOURCE COVER, LIGHT CONTROL MEMBER, AND LIGHT SOURCE UNIT

摘要

A lighting apparatus (100) comprises: an LED (10) which is a light emitting element; a substrate (20) on a front surface of which a plurality of the LEDs (10) are arranged and mounted; a housing (30) that is connected to the rear surface of the substrate (20); a diffusing plate (40) provided above the substrate (20); a reflecting plate (80) that is disposed on both sides of the substrate (20) and that supports the diffusing plate (40); and a light source cover (50) that is provided so as to cover the LEDs (10) and end parts of which are connected to the housing (30). The light source cover (50) comprises: a thickness portion (51) the thickness of which is uniform in cross section view; inclined portions (52) disposed beside the thickness portion (51) and the thickness of which, in cross section view, becomes thinner with distance from a light axis (11); and reflecting portions (53) that continue from the inclined portions (52). The light source cover (50) has a shape the cross section of which extends in the longitudinal direction of the substrate (20), and such light source cover may be manufactured by extrusion molding.
