PURPOSE:To facilitate fitting and removal of a photo-controlling body at replacement of lamp and accomplish an illumination fixture having fine appearance by achieving the fitting/ removal only through pressing the photo-controlling body from below the fixture body. CONSTITUTION:A lamp 4 is fitted in a fixture body 1, and at its undersurface a photo- projecting hole 2 is provided, and a photo-controlling body 5 is fixed at this opening 2 of the fixture body 1 in such a way as capable of being fitted and removed as desired. This photo-controlling body 5 is provided with a detent part 7, and the fixture body 1 is equipped with a latch mechanism 10 having a detaining part 16, which detains this detent part 7 by the first application of pressing force of the detent part 7 of the photo-controlling body 5 in the neighborhood of the opening and disengages the detention by the second application of pressing force. The photo-controlling body 5 is thus mounted with possibility of fitting and removal as desired. To replace lamp, the photo-controlling body 5 is pressed to the fixture body 1 side, and the detaining part of the latch mechanism 10 disengages the detention of the detent part 7 of the photo-controlling body 5, which is thus separated from the fixture body 1. When the lamp is lighted, the projected light under control by the photo-controlling body is cast downward and toward the ceiling. This ensures enhancing the operating easiness in replacement of lamp as well as provision of fine appearance. |
