Definitions

  • the invention relates to a luminaire for illuminating opposite shelves according to the preamble of claim 1.
  • the luminaire disclosed there has a luminous means arranged within a housing and a reflector arrangement arranged in the housing with a primary reflector and a secondary reflector.
  • the primary reflector is designed as a box reflector with a cold light mirror arranged above the light source, side reflectors and separate front side reflectors.
  • the secondary reflector is arranged below the luminous means and serves as a shield to reduce a direct light emission to the areas lying below the luminous surface areas.
  • the object of the invention is to provide a luminaire of the type mentioned, which is simple and allows easy replacement of the bulb.
  • the reflector arrangement can be folded out of the housing together with a luminous means base for holding the luminous means.
  • the light bulb can be easily pulled out to replace and replaced by a new light source. The replacement of a light source is thus considerably simplified.
  • the reflector arrangement and the luminous means base for accommodating the luminous means on a holder within a front housing part of the housing are arranged pivotable about a transverse axis.
  • a particularly effective and energetically efficient illumination of shelf alignment can be achieved in that the primary reflector in cross-section has the shape of two paraxial to a center plane axisymmetric. Due to the primary reflector thus formed, the light can be directed extremely far into the C0 or C90 plane in a batwing-shaped distribution and thus a uniformly homogeneous illuminance can be achieved from the shelf cover to the shelf.
  • the arranged below the light source secondary reflector expediently has an angular or triangular shape with two obliquely inwardly directed reflector surfaces. This can be an amplification of Batwing bins and a luminance reduction in a direct view from the bottom of the lamp are made possible.
  • the light source is arranged in a preferred embodiment in the center plane of the primary reflector parallel to the reflector opening, so that the light source is aligned horizontally in the operating position. This achieves a compact design with an extremely small reflector head.
  • FIG. 1 is the schematic diagram of a lamp 1 for lighting two opposite shelves 2 or similar goods presentation devices shown.
  • the suitably arranged above the shelves 2 in the middle of the tower lamp 1 includes at least one lamp 3 and a reflector assembly with a primary reflector 4 and a secondary reflector 5, which allow a uniform homogeneous illuminance from the shelf 6 to the shelf cover 7 on the two opposite shelves 2.
  • the schematically indicated main beam path 8 is steered so that the shelves 2 are uniformly illuminated from top to bottom, while the bottom 9 in the corridor zone between the shelves 2 remains largely unlighted.
  • a lamp 1 with such a reflector arrangement allows a so-called Batwing light distribution.
  • the lamp 1 includes a housing with a designated also as a reflector head front housing part 10 and a rear housing part 11 with an upper support member 12 through which the lamp 1 can be attached to a power rail or the like.
  • the lighting means 3 shown in dashed lines and the reflector assembly 13 with the primary reflector 4 and the secondary reflector 5 are housed.
  • the rear housing part 11 connecting elements, power supply elements, etc. are arranged.
  • FIG. 2 recognizable reflector assembly 13 with the in FIG. 3 shown primary reflector 4 and the secondary reflector 5 is arranged together with a bulb socket 14 for holding the bulb 3 in the front housing part 10 that they are folded out for easy replacement of the bulb 3 from the housing part 10, ie between a in FIG. 2 shown Einklapp- or operating position and a in FIG. 4 shown change position can be pivoted.
  • reflector assembly 13 and bulb socket 14 are hinged to a holder 15 within the front housing part 10 about a transverse axis 16 pivotally.
  • the luminous means base 14 is aligned such that the luminous means 3 in an in FIG. 3 shown center plane 20 of the reflector assembly 13 is arranged parallel to the reflector opening 21, ie in the operating position of FIG. 2 is aligned horizontally.
  • the reflector assembly 13 consists of the primary reflector 4 and arranged below the light source 3 secondary reflector 5.
  • the primary reflector 4 has in cross section the shape of two to the center plane 20 of the primary reflector 4 axisymmetric parabolas 4a and 4b. By thus shaped primary reflector 4, the light can be directed extremely far into the C0 or C90 plane with a Batwing-shaped distribution.
  • the luminous means base 14 is arranged parallel to the reflector opening 21 in the center plane 20 of the primary reflector 4, so that the luminous means 3 extends horizontally in the operating position.
  • the primary reflector 4 is preferably bent continuously, but may also be formed from a plurality of segmented individual surfaces.
  • the arranged below the light source 3 secondary reflector 5 advantageously has an angular or triangular shape with two obliquely inwardly directed reflector surfaces 22. As a result, it is possible to enhance the Batwing effect and to reduce the luminance when viewing the luminaire.
