ABSTRACT:
A light transmitting false ceiling made up of louvers and supporting runners, the latter being adapted to be suspended from a normal ceiling with lamps mounted above the false ceiling. The louvers have extensions at opposite edges for engagement with and support by the adjacent runners. The louvers are made up of intersecting members defining open cells therebetween. Each of the louver members as well as each of the runners is of upwardly open channel section. The runners have downwardly extending slots in their upstanding walls to receive hook-shaped extensions on the louver members, and these slots are wider at the top than at the bottom to facilitate installation on site. The widened runner slots on one wall of each runner are offset from those on the opposed wall by the width of the louver channel members. The hooked-shaped extensions on the members protrude into the channels of the runners and together with the bottom and upstanding walls of the runners block light leaks through the widened runner slots so that light is transmitted uniformly through the false ceiling to yield the appearance of a single large louver with no apparent seams.
