Definitions

  • the present invention relates to a luminaire, in particular a luminaire for illuminating corridors, such as, for example, corridors in which merchandise is stored, for example on shelves.
  • the goods are usually stored and offered on shelves or similar storage facilities.
  • the storage facilities are usually arranged in a gangway way so that customers can look at the goods from the aisles and remove them from the storage facilities.
  • To illuminate the corridor itself and the goods lights are usually arranged above the corridors. Since both the arrangement of the goods in the storage facilities and the arrangement of the storage facilities itself often changes, the illumination must be adjusted accordingly.
  • the lighting units each have LEDs and a reflector in the form of a curved plate extending over the entire length of the lighting unit. At the respective ends of this plate are obliquely outwards and downwards inclined, flat plates provided. This ensures that the intensity of the radiated light decreases steadily in the direction of the longitudinal extent of the luminaire, whereby hard transitions in the lighting are avoided.
  • a luminaire is provided with a carrier device and at least one lighting device extending in a longitudinal direction and mounted on the carrier device.
  • the lighting device has a carrier part extending in the longitudinal direction, a plurality of lighting unit units which are arranged on a side wall of the carrier part, and a reflector device attached to the carrier part.
  • the reflector device has at least two longitudinally spaced apart Reflector sections, which are each formed by in at least two directions of curvature concave reflector surfaces. The at least two reflector sections are oriented facing the side wall of the carrier part. Furthermore, a lighting unit is assigned in each case to one of the at least two reflector sections.
  • a luminaire is thus provided with a carrier device, which is provided for attachment to a ceiling of a building space, and at least one lighting device.
  • the at least one lighting device is mounted or arranged on the carrier device and thus mechanically coupled to the at least one lighting device.
  • the at least one lighting device has a carrier part or a support structure which extends in a longitudinal direction.
  • the at least one lighting device serves to emit light and accordingly has a plurality of lighting unit units which are arranged on the carrier part, in particular on a side wall of the carrier part extending in the longitudinal direction.
  • the support member may thus be designed, for example, as an elongated plate in the simplest case.
  • the at least one lighting device furthermore has a reflector device for reflecting the light which can be emitted by the lighting unit.
  • the reflector device has at least two reflector sections or reflector regions which are spaced apart in the longitudinal direction and which are each formed by reflector surfaces which are concavely curved in at least two directions of curvature.
  • the individual reflector sections thus each form open cavities which are separated from one another with respect to the longitudinal direction and which are defined or delimited by reflector surfaces provided for reflection of light.
  • the at least two reflector sections are oriented facing the side wall of the carrier part, that is, the respective reflector surfaces are the Side wall, on which the lamp units are arranged facing oriented.
  • each reflector section is assigned at least one luminous means unit or arranged opposite to it on the side wall, so that light can be emitted to the surface forming the respective reflector section and reflected by the latter for illuminating an illumination area.
  • the curvature of the reflector surfaces is designed in such a way that the light which can be emitted by means of the illuminant units is reflected in a direction transverse to the longitudinal direction.
  • the reflector surface is enlarged in the longitudinal direction relative to the length of the lighting device.
  • the length of the lighting device and thus the lamp is advantageously reduced.
  • one reflector section is irradiated by one or more individual illuminant devices, a very high light output per reflector section is achieved. Based on the length of the lamp thus the light output is increased.
  • a particularly uniform light distribution is achieved by the concave, multi-axial curvature, in particular with respect to the longitudinal direction.
  • the special curvature of the reflector sections causes a larger area to be illuminated by two or more reflector sections than with conventional lights of the same size. Furthermore, the curvature of the reflector sections and their separate arrangement prevents dazzling with respect to a viewing direction along the longitudinal direction in an improved manner.
  • the number of luminous means units can correspond to the number of reflector sections, and in each case one luminous-element unit can be arranged opposite a respective reflector section and associated therewith. In this case, exactly one illuminant unit is thus provided per reflector section. This offers the advantage that a large illumination area can be illuminated with a minimum number of light sources. The space requirement of the lamp units is thus reduced, which promotes a compact construction of the lamp.
  • cooling chimneys for example in the form of channels, which each have two openings which are opposite in the luminaire device vertical direction and which are connected by peripheral walls of the respective cooling chimney.
  • the peripheral walls thus define the cross-sectional shape of the respective chimney and extend between the opposed openings.
  • cooling chimneys are formed on the side wall of the support part, on which the light emitting unit are arranged, one of Perimeter walls formed by the side wall of the support member. Consequently, cooling chimneys improve the heat dissipation from the lighting unit, since the extension of the cooling chimneys in the light fixture vertical direction causes the chimney effect which arises as a result of the heating of the side wall for improved convection. As a result of the improved cooling, the efficiency of the lighting unit can be further increased and thus the number of lighting unit units necessary for achieving a desired lighting power can be reduced. Consequently, the lamp can be made smaller and more compact.
  • the carrier part of the light-emitting device has a plurality of ribs which extend from the side wall of the carrier part at least in sections along a light device vertical direction extending transversely to the longitudinal direction. Accordingly, the carrier part has a plurality of ribs arranged on the side wall, which are arranged spaced from one another with respect to the longitudinal direction. It can be provided that the ribs in one piece formed with the side wall of the support member or are attached thereto, for example, material, positive or non-positive. An at least partially extending along the light device vertical direction can be realized for example by L-shaped or arch-shaped ribs.
  • the ribs Due to the direct contacting of the ribs with the side wall of the carrier part, the ribs are thermally coupled to the side wall. As a result, the surface of the carrier part is increased, thereby further improving the heat dissipation and cooling of the illuminant units.
  • mounting surface for example for fastening the reflector device, is advantageously provided by the ribs.
  • the at least one lighting device further comprises a cover strip, wherein the cover strip on a first surface the side wall of the carrier part, on which the Leuchschüen are arranged, is arranged.
  • an elongate strip that is to say a strip extending along the longitudinal direction, is arranged on the inner surface of the side wall facing the reflector device and thus projects from the inner surface.
  • the bezel is disposed between a lower end portion and the respective lamp unit with respect to a lamp width direction extending across the lamp height direction.
  • the illuminant units are shaded by the strip with respect to a viewing direction along the luminaire elevation direction, so that an aperture is prevented by the illuminant units in an improved manner.
  • the reflector surfaces forming the at least two reflector sections and the cover strip jointly define a respective respective light exit opening of the luminaire.
  • the respective reflector surface extends up to the cover strip or ends at this.
  • a reflector intermediate segment, which extends with respect to the longitudinal direction between two successive reflector sections, is thus in contact with the cover strip. For a particularly good glare is achieved at a viewing direction obliquely to or along the longitudinal direction.
  • the luminous means can each be designed in particular as LED illuminant units.
  • a light-emitting unit comprises one or more light-emitting diodes, in short LEDs. LEDs offer the advantage that high light levels are achieved with relatively low heat output.
  • the illuminant units may be designed as chip-on-board LED units or as chip-scale packaging LED units.
  • COB is an abbreviation for the English term chip-on-board.
  • COB-LED units have a plurality of LED elements or LED chips which are arranged on a carrier substrate and are connected there electrically in parallel or in series and are provided with a cover layer, e.g. a phosphor layer, are covered.
  • COB LED units have a high power density based on their space requirements, which facilitates a compact construction of the luminaire.
  • COB LED units have the advantage that they have a homogeneous beam quality and a high color rendering index.
  • Chip-scale packaging LED units, in short CSP-LED units also have a high power density based on their space requirements.
  • the orientation of the lighting device and thus the emission direction of the light that can be emitted by means of the illuminant units via the reflector sections can be adjusted. This advantageously increases the flexibility in mounting the luminaire relative to an area to be illuminated.
  • the carrier device has a longitudinal carrier extending in the longitudinal direction, a first transverse carrier arranged at a first end section of the longitudinal carrier and extending transversely thereto, and a second transverse carrier which is arranged at a second end section of the longitudinal carrier and extends transversely to the side member.
  • the at least one lighting device may be mounted, for example, on the cross members.
  • the support means may also be formed as a peripheral rectangular frame.
  • the carrier device thus has two longitudinal struts extending in the longitudinal direction and two transverse struts extending transversely thereto and connecting them.
  • a circumferential bar protruding outward from the struts may be provided on the carrier device.
  • the peripheral frame can be advantageously used in a mounting recess, which is provided for example on a ceiling of a building room.
