PURPOSE:To facilitate installation and lessen dispersion of the mounting strength by screw-fitting lighting circuit components and a light emitting tube to a cover through a support. CONSTITUTION:A chassis 8 as a support is accommodated in an envelope 1. To this chassis 8 are fixed a stabilizer 9, a fluorescent lamp 10, and a lighting tube. These stabilizer 9 and lamp 10 are mounted to a cover 2 with fixing of the chassis 8 to the cover 2 with screws 22. On the inner surface of this cover 2 a mounting boss 17 is formed to constitute a wall thickness, and the screws 22 are driven into this boss 17, which increases the strength of this place of fixation. This eliminates fear of deformation of the cover 2. |
