The present invention relates to partition wall lamps to be arranged in a partition wall (100) between two interior rooms (104, 105) or an outer space. The partition wall lamps consist of glazings (13, 14) in the partition wall plane, wherein within said partition wall (100), in the lower lamp portion, illuminants (103, 10, 22) are horizontally disposed. 1Iiuminants (103, 10, 22) are partly wrapped by primary reflectors (11, 23, 34). Within said partition wall, furthermore, secondary reflectors (12, 28, 37) are provided. The invention is characterized in that said primary reflectors 11, (23, 34, 36) are concave parabola-like formed so that light radiation (24, 25, 26, 27) reflected by them is upwardly deflected at flat angles, in the majority of cases < 40° relative to the vertical, onto a secondary reflector. The secondary reflectors above the illuminant are disposed within the partition wall cross sections. Light (31, 32) deflected at secondary reflectors (12, 28, 37) is deflected downwardly onto the work place. The distance D between the primary reflectors and the secondary reflectors amounts to at least the fourfold of the reflector width b. The partition wall lamp is incorporated in the high window area of a partition wall at a minimum height of 1.90 m above top level of the ground floor. |
