Abstract

Despite the use of a reflector (5) for directing the light, it is the aim in an outdoor-lighting fitting having a transparent lighting fitting housing (1) to obtain the visual outward appearance when the light source (3) is switched on in a manner adapted to the outward appearance in daytime, and to obtain in the event of a sufficiently high proportion of light directed onto a working surface as uniform as possible a distribution of brightness on the surface of the lighting fitting housing (1). This is achieved by using for the body of the reflector (5) a cloudy, translucent carrier material which is evaporated on with a partially transmitting reflective layer in the visual wavelength region. It is thus possible, in particular, for light fittings in pedestrian zones to be attractively styled and at the same time optimised in terms of lighting technology. <IMAGE>
