PURPOSE: To provide a housing system capable of being used for an existing ceiling and a new building by providing a rectangular mounting plate, a nearly circular and vertically extending flange having substantially the same diameter as the width of the mounting plate, and a cylindrical lamp housing. CONSTITUTION: This housing system is provided with a generally flat and rectangular mounting plate 13, the vertical length of the plate 13 is substantially longer than the width, a nearly circular and vertical flange 15 extends downward from the lower face of the mounting plate 13, the diameter of the circular flange 15 is substantially equal to the width of the mounting plate 13, and the gap between the flange 15 and another obstacle is minimized. A nearly cylindrical lamp housing 17 is secured to the mounting plate 13, and the axis of the housing 17 nearly coincides with the vertical flange 15. A junction box 27 is secured to the mounting plate 13, and an electric conduit 33 electrically connects the junction box 27 and the lamp housing 17. The housing system for a ceiling mounted luminaire capable of being used for a new or existing ceiling facility can be obtained. |
