  • the fluorescent lamps are arranged in peripherally located housing regions and between these lamp housing for particular lateral housing areas, a light emitting surface is formed at least on the room side, which has a special prism design.
  • Reflectors associated with the fluorescent lamps in cooperation with the prism surface, attempt to achieve as uniform a luminance as possible at the light emission surface.
  • the achievable reduction in the height of the luminaire is limited by the required uptake of the fluorescent lamps in the lateral housing areas and also the achievable illuminance and luminance distribution over the light emitting surface of the luminaire leave something to be desired.
  • a lamp of the generic type is further from the DE 103 44 066 A1 known.
  • This lamp has two end fitting carrier with which at the two end faces of the lamp a support frame is connected, which has a bottom and a raised edge with respect to the bottom.

  • the entire outer surface of the carrier profile is preferably used as a reflection surface, wherein the room-side, designed as a tip end of this hollow profile is located immediately adjacent the room-side light exit surface to use all possibilities for minimizing the overall height of the lamp.
  • a lamp according to the invention may have a length of more than 3 m, it is important that the carrier profile used has a high deflection stiffness.
  • the desired high deflection stiffness is achieved by the selected cross-sectional shape of the profile on the one hand and on the other hand, in that sections of a stiffening profile can be clipped into the hollow profile, which lead to a stiffening multi-chamber structure.
  • the top open side of the carrier profile can be closed by a strip-shaped stiffening lid, so that overall an unusually rigid overall arrangement arises.
