Abstract

According to one embodiment, there is provided a lighting fixture including a light source module and a support unit. The light source module includes a case which has the shape of a tube extending in a first direction, includes an opening, a substrate on which plural light sources are provided, and which is held in the case so that the plural light sources face the side opposite to the opening, and a mounting plate which is held by the case while being inserted between the opening and the substrate and is thermally connected to the substrate. The support unit includes a support plate which supports the light source module, and a frame which surrounds the outer edge of the support plate. An end portion of the light source module in the first direction is covered with the frame. The respective light sources are not covered with the frame.
