ABSTRACT:
The invention relates to a lighting assembly (10) comprising a housing (12), with one or more openings (26, 28, 30). A lighting means (40) is arranged in this housing emitting radiation through the openings (26, 28, 30) in angular ranges. Means (72) for shielding said radiation from a distant observer are provided. The invention comprises a first transparent cover (32; 72) for covering the openings of the housing. The cover has a micro structure profile (102) to shield unwanted radiation from selected portions of the angular ranges. A second transparent cover (70) protects the micro structure profile of the first cover.
