Definitions

  • the invention relates to a lighting armature provided with a box-shaped housing comprising an upper plate, side walls extending transversely to said upper plate, at least one light source disposed within said box and a reflector disposed within said box and extending in the longitudinal direction thereof, which reflector is substantially curved when seen in cross-sectional view.
  • the reflectors are provided with slots, in those parts that are screened from direct incidence of light from the light source(s) by further parts of the reflector.
  • a further drawback of known lighting armatures is the fact that light is reflected from the flat or usually curved overhead/roof mirror positioned above the lamps to the side mirrors positioned beside said mirror, and only then falls into the room to be lighted. To a large extent the light beamed into the room from the overhead/roof mirror via the side mirrors leaves the armature at large emission angles with respect to the vertical.
  • the area in the room that is lighted by a lighting armature will be comparatively wide, whereby, if the armatures are installed at a height of 2.50 - 2.80 m and with a mutual spacing which is usual in modulated offices, the lighting intensity in an area approximately centrally between two lighting armatures disposed in the room will be higher than near areas located nearer the lighting armatures.
  • the reflector is according to the invention provided with a few reflecting parts, which are interconnected at their ends by connecting parts, which are screened from direct incidence of light from the light source by said reflecting parts.
  • the reflector in particular the part of the reflector which is positioned higher than the light source(s), may be formed with a more or less serrated profile, whereby the relevant reflecting parts of the reflector may be designed and disposed in such a manner, that they are capable of reflecting light received from the light source(s) directly into the room to be lighted. This may be realized while maintaining a compact construction of the armature.
  • cross partitions are provided between the side walls 2 at the ends of the lighting armature, whereby said cross partitions are provided with means for supporting (a) light source(s), usually an elongated fluorescence lamp 3, under which lamp a grid 3' may be provided.
  • light source(s) usually an elongated fluorescence lamp 3, under which lamp a grid 3' may be provided.
  • a central part 4 of the upper wall also constitutes the central part of a reflector of the lighting armature.
  • this part 4 of the upper wall which constitutes a central part of the reflector, is disposed above the light source 3, in practice it is also called the "overhead or roof mirror".
  • Said roof mirror 4 comprises a central part, which is built up of two abutting parts 5 and 6 being disposed symmetrically with respect to a vertical longitudinal centre plane of the lighting armature and being slightly curved, when seen in sectional view, whereby the point at which the slightly curved (seen in sectional view) parts 5 and 6 extending in the longitudinal direction of the lighting armature abut each other is positioned lower than the other portions of said parts 5 and 6.
  • connecting parts 7 and 8 respectively extending at least substantially parallel to the vertical longitudinal centre plane of the armature, in which connecting parts ventilation slots 9 are formed.
  • connecting parts 12 and 13 extending at least substantially parallel to connecting parts 7 and 8 abut against the ends of the curved parts 10 and 11 of the roof mirror 4 of the reflector that face away from each other, said parts 12 and 13 extending upwards from their abutment against parts 10 and 11. Also connecting parts 12 and 13 are provided with ventilation slots 14.
  • the curved (seen in sectional view) parts 10, 11, 15, and 16, which are disposed symmetrically with respect to the vertical longitudinal centre plane of the lighting armature extending through the connecting line between parts 5 and 6, may be designed to have a comparatively small radius of curvature, such that light falling on said curved parts 10, 11, 15, 16 from the light source 3 will be reflected directly into the room located under the lighting armature, without said light first falling on side mirrors 19 or 20, for example.
  • Ventilation slots 9 and 14 are formed in those parts of the reflector that are screened by further parts of the reflector in such a manner, that light from the light source cannot fall directly on the parts provided with ventilation slots, so that no light emanating directly from the light source can "disappear” through said ventilation slots. This also contributes substantially towards enhancing the efficiency of the light given off by the light source.
