<p>The invention relates to a luminaire comprising a housing (2) with a light emission window (3) , the housing comprising an elongated reflector element (4) which is concave towards the light emission window and defines a longitudinal axis. A light distribution element (7) is positioned in such a way that, during operation of the lamp, essentially all light originating from the electric lamp traverses a light distribution element before exiting the housing via the light emission window. The light distribution element is provided with alternating bright (8a, 8b, 8c) and dark bands (9a, 9b, 9c) extending along the axis and yielding areas of a relatively high and a relatively low luminance, respectively. The dark bands are diffusely transparent to light.</p> |
