  • a basic idea of the invention can be seen in equipping the luminaire housing or the luminaire body with a luminaire underside facing the observer and forming at least one light passage area for a portion of the light emitted by the lamp in this luminaire underside in addition to at least one light exit opening for a reflector arrangement assigned to a lamp.
  • the light transmission area serving to improve the light utilization of the at least one lamp interacts with an additional reflector, which is arranged in such a way that light of the associated lamp reaches the light passage area.
  • the at least one lamp associated with the reflector array is provided with a light-transmissive region, so that the correspondingly formed additional reflector can direct the light emerging here above or in the light passage region of the housing bottom.
  • the light passage area as the at least one light exit opening for a lamp-reflector assembly is integrated into the housing bottom and can be produced in one production step.
  • the light passage area in the housing underside of the luminaire housing according to the invention which is advantageously U-shaped and which advantageously has a relatively low edge of the luminaire as an approximately right-angled bend from the housing underside, can be formed as a perforated or perforated area.
  • the openings may be identical or different and also in the form of a pattern.
  • a light or color filter is arranged on the inside of the light passage area, predeterminable color effects can be achieved with the luminaire according to the invention. At the same time, the overall impression of the luminaire can be advantageously changed even when switched off.
  • the lamp has a nearly square design with a relatively flat, cuboidal sheet metal body as a lamp housing and a rectangular housing bottom side.
  • a lamp fluorescent tubes and reflector arrangements can be provided as parabolic reflectors, each with two side panels and cross blades in the light exit openings, these and the at least one light passage area are arranged parallel to each other.
  • the light-permeable region of the reflector arrangement is formed in the side part of the reflector arrangement which is adjacent to the light passage region of the housing side.
  • the light-transmissive region serving for coupling out a light component can advantageously be formed above the transverse lamellae, in particular in an upper longitudinal edge region of the corresponding side part of the parabolic reflector, when the additional reflector extends to approximately over this region.
  • the additional reflector consists essentially of a flat, in particular white painted reflector surface or plate and is mounted inclined in the lamp housing and / or equipment rack.
  • the oblique or inclined arrangement of the plate-shaped additional reflector of a mounting region which may be integrated in the equipment carrier, are specified.
  • the attachment area is then aligned obliquely upward with the appropriate angle of inclination, for example with an upper, free longitudinal edge close to the two-sided lamp sockets of the associated lamp.
  • the additional reflector stiffening tabs can be provided as a right-angled bends to the reflector surface, which can be integrated into the production.
  • a first embodiment of the lamp according to the invention can be equipped with four lamps, the four lamps are each formed with a parabolic grid for a direct light component with radiation in the light exit region of the housing bottom and open at the top for an Indirektlichtanteil by over the parabolic reflectors no top cover is present.
  • two lamps are arranged side by side, and the associated parabolic grid can be formed as a unit.
  • the lampholders, as well as the ballasts and other electrical devices may be suitably arranged on the equipment carrier, which is advantageously designed to be complementary to the luminaire housing.
  • two light passage areas, z. B. be designed as perforated areas, and with inserted light filter and backlit. In principle, only one light passage area can be provided.
  • the backlighting of the two light passage areas is achieved by means of two additional reflectors, which are each held at least over the inside, provided with holes side part of the parabolic reflector in a slanted arrangement and extend over the respective associated light passage area.
  • An alternative lighting education can have three lamps, each with a parabolic grid, which again are fluorescent tubes.
  • the lamp parabolic grid arrangements in three light exit openings of the housing underside are arranged at a distance from each other, and between each of a light passage area, for example as a perforation in the housing bottom, may be formed.
  • a substantially equal dimensioning of the light passage areas in comparison to the light exit areas or the aligned reflector arrangements is advantageous.
  • the light transmission areas are in turn backlit with the help of additional reflectors, which in the present case either of the partially perforated, inside side parts of the two outer parabolic louvre or extend from both partially perforated side parts of the middle parabolic grid to over the respective light passage area.
  • the luminaires according to the invention can also have an opal cover in the region of the light exit openings.
  • an additional reflector is then also arranged such that a light component of the associated lamp is deflected to an adjacent light passage region.
  • Fig. 1 shows a lamp 2 according to the invention, which is characterized by a flat, smooth housing bottom 6 as a visible surface without disturbing connecting elements, welds and butt joints.
  • This lamp 2 has a relatively low height due to a flat housing edge 7 and a device carrier 4, which is complementary to the U-shaped lamp housing 3 and exemplified in Fig. 3 is shown.
  • the luminaire 2 allows a ceiling pendulum mounting and a ceiling-mounted mounting and a ceiling semi-recessed mounting and adapted to the interior design of the dominant housing bottom side 6 of the lamp housing.

  • Fig. 1 has each light passage area 10 mutually offset rows of holes whose total width corresponds approximately to the width of a light exit opening 8. The longitudinal extent coincides with that of the light exit openings 8.
  • Both light passage areas 10 have oval or slot-like openings, wherein the openings of the respective middle row are larger or wider than that of the two outer rows.
  • the light passage regions 10 may also be formed as rows of holes with preferably round and staggered holes.
  • a deposited light or color filter 16 can increase the contrast to the light of the light exit openings 8 even more.
  • Fig. 2 to 4 clarify that each light passage region 10 light from the adjacent lamp reflector assembly 5 by means of an additional reflector 11 and at least one light-transmissive region 15 in the reflector assembly 5 is supplied.
  • each additional reflector 11 is plate-shaped and has a flat, in particular painted white reflector surface on its underside.
