Abstract of the Disclosure Light fixtures with a rod-shaped light source (1) and with concave reflectors on both longitudinal sides of the light source. The concave reflectors extend above the light source, and have a curvature such that all light rays reflected across the light source will emerge in the transverse direction either directly or after reflection at an angle that is steeper than a light-specific masking angle (.alpha.). The reflectors include lamellae (4) that have an approximately V-shaped cross section and run across the middle vertical longitudinal plane of the light source and have reflecting concave side surfaces with a curvature such that all light rays reflected in the longitudinal direction of the light source (1) will emerge in the longitudinal direction either directly or after reflectiona t an angle that is steeper than a light-specific masking angle (.beta.). the top sides (8) of the lamellae are covered by a flat reflecting cover, and the lamellae are shaped so as to form two lamellar sections that are symmetrical with the middle vertical longitudinal plane; their flat top sides, starting below the light source, form an angle with the longitudinal plane that approximately corresponds to the masking angle (d) and have the opposite slopes such that they are in tangential proximity to the light source (1) but do not come in contact with it, and they extend as far as the reflectors (2). 2601-1-0022
