ABSTRACT:
A lighting apparatus (10) is described for incorporation into a tiled wall, panel, ceiling, floor or similar structure (38,40). The apparatus comprises: a reflector unit (12, 14) that has at least one reflective surface (24, 26) for location behind the surface of the structure and an external light-transmissive face (14) for location generally flush with the surface of the structure; and means (28) for coupling an end of a fiber-optic cable (32) having a multiplicity of optical fibers (34) to the reflector unit behind the surface of the structure so that light projecting from the ends of the fibers enters the reflector unit and is reflected by the reflective surface(s) so as to provide substantially uniform illumination across the light-transmissive face. The reflector unit is formed with an external flange (20) generally parallel to the light-transmissive face. This facilitates positive fixing of the apparatus to the substrate of the wall or ceiling, for example using tile cement, and enables repositioning of the apparatus and surrounding tiles until the cement is dry.
