Abstract (en)

[origin: EP0472288A2] The invention provides a housing (11) comprising a metallised reflector (3) having specularly (7) and diffusely reflective (8) portions. The portions reflect the light from a light source (10) which lies substantially diagonally within a substantially square section of the lamp housing (1) such that light is evenly reflected onto a floor below. A separate skirt may be attached for use in a high ceiling environment to focus the light. <IMAGE>
