Definitions

  • An example of a luminaire with multiple LED light sources is from DE 10 2008 052 869 A1 known.
  • a plurality of LEDs are mounted on a mounting rail to be mounted in the luminaire.
  • the reflectors, as far as provided for the LEDs are firmly connected to the LED and are fastened with a headband to the mounting rail.
  • the present invention solves the problem by a luminaire according to claim 1 and by a method for mounting such a luminaire according to claim 13.
  • At least one circuit board which carries the semiconductor light source, is preassembled together with a reflector on a device carrier.
  • a retaining clip is provided, which already holds the board and the reflector on the equipment carrier before the equipment carrier is mounted in the lamp housing.
  • This type of luminaire therefore allows mounting in two steps. First, the pre-assembly of the board and the reflectors on the equipment carrier and only then the installation of the device carrier in the lamp housing. It is advantageous that the retaining clip is already set up to align the board with respect to the reflector, so that a precise arrangement between the optical components of the lamp is possible. This task alone would already be fulfilled by a centering aid, such as a centering pin or the like.
  • the engagement of the retaining clip in the device carrier may be formed by a positive connection so that the angular position is firmly defined to align the reflector and the board relative to the equipment carrier at a certain angle.
  • the reflector is fixed relative to the device carrier by one or more abutment edges in the angular orientation.
  • the retaining clip on one or more, in particular two opposite or more arranged on a circumferential circle locking lugs, which engage in engagement with the device carrier behind an edge thereof.
  • the retaining clip may be divided into two at the end facing the equipment carrier in the longitudinal direction, wherein the resulting legs are elastically braced in a section of the equipment carrier so that the detents engage at a peripheral edge of an opening on the equipment carrier.
  • Other locking connections are possible.
  • more than two legs may be formed, which engage in engagement with an opening of the device carrier behind a peripheral edge, each with a detent. The locking is preferred because it can be easily solved on the reflector and the board opposite side of the equipment carrier to disassemble the components again.
  • the retaining clip is formed from plastic. This not only allows easy production but the plastic material also provides the necessary elasticity to form resilient areas for the locking lugs.
  • the device carrier is mounted in the housing by releasable mechanical connecting elements, in particular by screws. This allows easy disassembly of the device carrier. Thereafter, the reflector and the board can be removed by loosening the retaining clip again from the device carrier.
  • the board and the reflector are separable from each other when the device carrier is removed from the lamp housing for disassembly of the lamp and the retaining clip is removed.
  • This allows the complete disassembly of the individual components, as is often not the case in the prior art, because the boards are glued to the semiconductor light sources fixed to the associated reflector. According to the invention can be dispensed with such a bond.
  • the method for mounting a luminaire provides in succession the pre-assembly of the board and the reflector on the device carrier by means of the retaining clip and then the mounting of the device carrier in the housing. It is important in this context, the order of the process steps, because thereby the handling advantage is achieved when assembling the lamp.
  • After mounting the device carrier in the housing may also be a final assembly by closing the housing with a cover.
  • the device carrier can be mounted in the housing through the light exit surface of the luminaire and the light exit surface can subsequently be closed by a transparent or translucent cover.
  • the cover itself can be used to the device carrier in the housing clamp it while doing the clamping between the housing section and the device carrier for fixing the board and the reflector. In this embodiment, a screwing of the device carrier in the housing is not necessary.
  • the luminaire of the described embodiment comprises a device carrier 2 (see FIG. 1 ), which in a lamp housing 4 (see FIG. 4 ) is inserted through a light exit surface and screwed into it.
  • the assembled luminaire in supervision of the light exit surface is in FIG. 5 shown.
  • the FIG. 1 shows the equipment rack 2 in a preassembled state, in which four reflectors 8, each with a board 10 are attached to the equipment rack.
  • the reflectors 8 comprise two flared chambers, each leading to an opening, that of a light passage opening is assigned in the equipment carrier extend.
  • the chambers which can also be connected to each other, one or more LEDs (Light Emitting Device) are arranged, which are mounted on the board located above 10 and electrically contacted. Further details of the reflector shape which can be used according to one embodiment are disclosed in the European patent EP 2 360 427 described.
  • the assembly consisting of a reflector 8 and a board 10 is by means of a retaining clip 12, which as a single part in FIG. 2 is shown attached to the equipment carrier 2.
  • the retaining clip 12 comprises a flange 14, a cylindrical portion 16, and two spring arms 18 each having a latching projection 20 at the outer end.
  • the boards 10 and the reflectors 8 are aligned with respect to light passage openings 28 in the equipment carrier 2. At least one edge, preferably two edges, of the reflector 8 abut against the edge of the light passage opening 28 in order to determine the angular orientation of the reflector 8 relative to the device carrier. Preferably, the edges of the reflector 8 are matched to the light exit opening 28 so that the mounting of the reflector 8 in two different directions is possible. A slight clearance between the reflector 8 and the light passage opening can be provided, so that the reflector 8 can rotate relative to the device carrier 2 by no more than 3 °.
  • This preassembled device carrier 2 is then introduced into the housing 4 through the light exit surface and screwed into the housing 4.
  • the housing is preferably made of a thermally conductive material, such as aluminum die-cast, and serves not only as a housing but also as a heat sink for the LEDs on the boards 10. By a good thermal coupling therefore cooling of the semiconductor light sources is possible.
  • the flange 14 may either abut the housing or be exposed in a recess of the housing in the assembled state, as in the FIG. 3 you can see. In any case, however, relieved by the jamming of the board and the reflector between the housing portion 26 and the device carrier 2 of the retaining clip, so that the locking connection between the locking lugs 20 and the device carrier 2 for mounting on the board 10 and the reflector 8 no functional significance has more.
  • the mounted light such as in FIG. 5 can then still with a transparent cover (not shown in the figures) are closed.
  • the device carrier 2 not only has cutouts in the form of light passage openings 28 but also in the middle even a larger section 30, in which an electronic ballast or other equipment of the lamp can be mounted.
  • a support for a ballast is attached, which completely closes the cutout 30 in the direction of the light exit surface.
  • two pairs of light passage openings 28 are not occupied by an assembly of reflector and board, but closed by a blind cover.
  • the retaining clip 12 in the region of the flange 14 has a centered opening 32.
  • This opening 32 of the retaining clip 12 can Pins of a mounting device (not shown in the figures) are plugged to arrange a plurality of retaining clips 12 in space.
  • the boards 10 and the reflectors 8 are plugged for pre-assembly of the device carrier 2.
  • the device carrier 2 is attached via the plurality of retaining clips 12 and locked with the retaining clips 12.
  • a preassembled device carrier is obtained as a result FIG. 1 , which can then be screwed into the luminaire housing for final assembly.
  • the number of reflectors and boards, the shape of the device carrier and the housing, as well as the type of fastenings of the equipment carrier in the housing can be changed without departing from the scope of the invention.
  • the cover of the lamp itself can be used to attach the device carrier.
  • the shape of the lamp is not limited to round lights but may according to further embodiments comprise square or rectangular cross-sections.
  • the number of reflector and board assemblies can vary.
  • the shape of the retaining clip can also be changed.
  • no cylindrical portion 16 is necessary but it can also be used in a square cross-section column use, with correspondingly shaped openings in the board and in the reflector are available. This allows the board and reflector to be aligned with respect to the equipment carrier. In the illustrated preferred embodiment, separate positioning means are provided on the reflector and on the board, respectively, to ensure angular alignment.
