Definitions

  • the invention relates to a luminaire for ceiling installation, ceiling surface mounting and pendulum suspension with a box-shaped housing, a grid inserted into the light outlet opening from lamellar interconnected slats with at least approximately double parabolic cross section, which with the least possible loss of coverage of the light of the lamps arranged above the grid in the housing the shielding required according to the respective requirements at the workplace or in the room.
  • Luminaires of this type are known, for example, from the literature reference Siemens Elektrodienst, 22nd Year, Issue 3, April 1980, pages 4 and 5.
  • the 90 ° angle range can be divided into the beam area and the dark area in a way that deviates from the angle values specified in the BAP condition.
  • the dark area is defined in the direction perpendicular to the axis of the fluorescent tube by an appropriately designed trough-shaped reflector with a parabolic cross section and in the direction of the axis of the fluorescent tube by a grid inserted into the light exit opening Lamellas with double parabolic cross-section reached, which are arranged at mutually equal distances parallel to each other and perpendicular to the axis of the fluorescent tube.
  • the mutual spacing of the slats is selected taking into account the height and the cross section of the slats so that the desired shielding is achieved with the least possible coverage of the light from the fluorescent tube.
  • linear luminaires which fulfill a special shielding condition can be used to achieve an omnidirectional characteristic in such a way that a plurality of such linear luminaires are arranged in a ring in the manner of a light strip.
  • a ring arrangement is only possible where there is sufficient ceiling space available due to the size of the room.
  • the invention has for its object to provide a solution for the design of a grid from omnidirectionally connected lamellae with at least approximately double parabolic cross-section for a luminaire with omnidirectional characteristic, which also meets special shielding conditions according to the BAP condition and with the lowest possible coverage losses of the lamp light.
  • the invention is based on the essential finding that the desired grid structure from a lamella composite with lamellae which have an at least approximately double parabolic cross-section can then be realized in an extremely simple manner by starting from a ring-shaped grid center cell which fulfills the desired shielding condition and further dividing the center-symmetrical grid into themselves same segments is used.
  • the desired shielding condition is met in the structure of the grid shown in FIG. 1 for each frame cell, as indicated in FIG. 1, if the diagonal of a frame cell does not exceed the value 2 Ro.
  • Optimal conditions with the least possible loss of coverage of the lamp light by the grid are achieved if the diagonals of the frame cells have exactly the value 2 Ro.
  • the radii R1, R2, R3 for the subdivision of the segment result for both segments 1 according to FIGS. 1 and 2 in each case by the condition on which they are based either that the Diagonal or the tendon of the largest arcuate side of a frame cell has the value 2 Ro.
  • the closed frame cell structure of this segment has two radial main fins 4, which are connected to one another via six circular arc sections with connecting fins 50, 51, 52, 53, 54 and 55 representing the radii R0, R1, R2, R3, R4 and R5.
  • radial intermediate plates 510, 521 and 522, 531 to 533 and 541 to 544 are also provided.
  • a rotationally symmetrical grid 9 which is formed from six segments 1 according to FIG. 3, is provided and fills the light exit opening of the housing 6.
  • three compact fluorescent tubes 7 with a base on one side are provided in a triangular configuration above the grid 9. 3 has the diameter 2 Ro.
  • the rotationally symmetrical lamp according to FIG. 5, which corresponds in its dimensions as well as in the design of the grid 11 to the lamp according to FIG. 4, likewise has three compact bases on one side.
  • Fluorescent tubes 7, which, however, are the same in a star shape here Angular distances of 120 ° are arranged in the housing 6.
  • the greatest length of a straight frame side of a frame cell is 2 Ro.
  • the lamp according to FIG. 6 again has three compact bases on one side Fluorescent tubes 7, which are arranged in a star shape in the housing 8 corresponding to the compact fluorescent tubes 7 of the lamp according to FIG. 5.
  • the radial main plates 4 are each connected to one another by connecting plates 50, 51 and 52 which represent only three circular arcs.
  • the frame cells cannot be optimized with regard to the value 2 Ro, because the overall diameter of the grid is predetermined by the light exit opening of the lamp to which it is assigned.
  • a subdivision of the cell formed by the radial main lamellae 4 and the connecting lamellae 50 and 52 by the connecting lamella 51 is necessary because otherwise the frame cell would be so large, i.e. that both the diagonal and the chord of the largest arcuate frame side have the value 2 Ro exceeds.
  • the subdivision with the connecting lamella 51 in turn results in frame cell sizes, the diagonal or the chord of the largest arcuate side of which is significantly lower than 2 Ro.
  • the connecting slats 51 chosen in height smaller than the other slats.
  • the arrangement is such that the connecting slats 51 are arranged on the foot side in the plane which is determined by the wide ends of the remaining slats of the laminate assembly on the foot side.
  • Such a measure can always be used if the frame cells of the grid cannot be optimized with regard to the value 2 Ro by predetermined dimensions.
  • a lamella with a reduced height can be used between two successively identical lamellae running perpendicular to the radial direction or perpendicularly to the receiving direction, and that apart from the radial main lamellae be provided, with all of the intermediate lamellae adjacent to a shortened connecting lamella and extending in the radial direction also to be shortened.
  • the intermediate lamellae adjacent to this shortened connecting lamella are also as indicated in Fig. 3 with 510, 521/522, 531/532/533 and 541/542/543/544, to shorten accordingly.
  • FIGS. 8 to 10 show further advantageous arrangements of lamps in a lamp housing with a center-symmetrical light exit opening.
  • four compact fluorescent tubes 7 with one base are provided here.
  • this arrangement of four represents a center-symmetrical cross. Both figures differ in that in Fig. 8 the base of the compact fluorescent tubes 7 on the housing circumference and in the embodiment according to Fig. 10 in the center of the housing.
  • the luminaire according to the invention can be used as an office luminaire in a wide variety of designs and configurations.
