PURPOSE:To improve working property of electronic apparatus installation by forming a ballast receiving part of vertically halved outer shells, and fixing electronic apparatuses such as a discharge lamp ballast in the outer shells. CONSTITUTION:A ballast receiving part 1 is formed of halved outer shells 1a, 1b, and electronic apparatuses such as a discharge lamp ballast 3 and a switch 4 are fixed in the outer shells 1a, 1b. A hook 5a and a welding bolt 5b for installation of the discharge lamp ballast 3 and a mounting plate 5c for installation of the switch 4 are fixed to a mounting frame 5 onto which each electronic apparatus is mounted. The mounting frame 5 is fixed to mounting members 2a 2b provided between two struts by bolts 8 and nuts 9, and the discharge lamp ballast 3 and the switch 4 are then mounted onto the mounting frame 5 followed by wiring. As the ballast receiving part is halved, the wiring work for electronic apparatus installation is facilitated. |
