<p>A lighting fixture (1) for installing in a false ceiling consists of a rectangular frame with turned out lower flanges (6) which fit flush with the ceiling panels. The frame is supported from the ceiling beams by four flat bars (9). The bars project through slots cut in the side members of the frame (1) near the corners. The inner ends of the bars (9) are supported by brackets having slots with serrated edges. By choosing the correct combination of a slot in the frame and a serration in the slot in the bracket (11), the bars can be adjusted to support the frame at the correct height so that the flanges are flush with the surface of the false ceiling.</p> |
