PROBLEM TO BE SOLVED: To enable securing of rigidity of a lighting apparatus only by installing a bridge frame part on a part, without installing a frame member on the whole rear face of a light source unit.SOLUTION: A pair of frame members 4 have opening parts respectively opposed to each other on the opposite side (upper side in the drawing) to the emitting side of illumination light L2 in the lighting apparatus 101, and have grooves 4d formed along the longitudinal direction (vertical direction on the drawing) of the frame members 4. A bridge frame part 9 is bridged on the pair of frame members 4 in the state both end parts are inserted slidably into the respective grooves 4d. Thereby, even if the frame members are not installed on the whole rear face of the light source unit, only by installing the bridge frame part on a part, the rigidity of the lighting apparatus can be secured. |
