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.
