A lighting apparatus has an arrangement (2) which includes light sources (42), reflector means (54), and a window (14). The reflector means are configured for 5 reflecting, through the window, light that is transmitted from the light sources across the inner side of the window. The reflector means includes reflector elements in the form of prismatic lenses (58) which are angled relative to one another to distribute the reflected light over the window. The arrangement also includes baffle reflector plates (64) adjacent the light sources for blocking some of the light from the light sources. 10 The apparatus can be used for back lighting of translucent signs, and for room lighting. o. -o 0 ecc |
