  • tongues are provided which are inclined in order to dig into an installation opening when installed. These tongues can also fulfill another function.
  • ceiling constructions are often covered on the back with a textile fleece. The tongues can be used during installation of the holding element to cut out such a textile fabric at the desired position, ie generally via an installation opening.
  • the holding element is locked in a plate by means of a press-fit ring which engages through the central recess.
  • a press-fit ring ensures that the tongues are pressed against the inner surfaces of the installation opening and also remain in this position.
  • the press-fit ring can serve as a channel for the light output .
  • the LED installation module initially separate from those for installation provided for. This makes it possible, for example, the plate, which is to carry the lighting assembly to equip with the holding element and separated from this, the wiring of the LED mounting modules with each other and possibly make with a control gear.
  • the thus pre-wired LED built-in modules can then be connected without much effort and without special expertise with the pre-assembled holding elements, in particular snapped into this.
  • Such a snap connection is preferably realized by means of a holding element, which consists of a spring formed from two spring legs and a crosspiece.
  • the spring legs at their free end in each case a hook-like bend, wherein these two bends are adapted to engage snapping in assigned Freiappelisme the heat sink to the structurally combined arrangement of LED unit and heat sink to lock.
  • a recess is preferably provided to allow a light exit on the holding element over.
  • a printed circuit board equipped with one or more light-emitting diode chips is preferably used, wherein the light-emitting diode chips are arranged under a common optical system.
  • This printed circuit board is preferably connected to the heat sink by means of a double-sided and thermally conductive adhesive tape.
  • the heat sink a Form receiving space through which electrical lines, which are connected to the LED unit, are guided.
  • a strain relief for the electrical lines can be provided on the heat sink.
  • a T-shaped exemption is provided at least in a side wall of the heat sink, which can be used together with a cable tie for strain relief when the cable tie is wrapped around the electrical wires and the exemption.
  • Two such exemptions are preferably provided in order to receive the connection from an operating device or an upstream LED installation module to the LED installation module and a forwarding to a next LED installation module.
  • the LED unit will usually be mounted on the outside of the heat sink. This means, however, that the electrical leads can not be led without special precautions in the interior of the heat sink, ie in the receiving space. Therefore, a slot open towards the receiving space can be provided on the receiving space of the heat sink over its entire height so that an insertion of the electrical lines is made possible.
  • the lighting arrangement according to the invention consists of a plurality of distributed light exit points, which are formed with the LED built-in modules according to the invention.
  • LED installation modules are preferably connected to one another via electrical lines connected. In general, this is done by a series circuits, but also parallel connection or in particular a combination of both types of circuits is possible.
  • the LED built-in modules can be connected in the context of this invention in the manner of an LED string of lights and electrically powered by a common operating device.
  • An operating device is preferably accommodated on or in a revisable region of a ceiling or wall.
  • the cooling body seen from above has an approximately rectangular cross section with longitudinal sides and transverse sides. If a plurality of adjacent LED built-in modules are arranged offset from each other in such a way that a longitudinal side of a first heat sink is located next to a transverse side of a second heat sink, it is ensured that a minimum distance remains around each heat sink. Thus, each heat sink is surrounded by sufficient air and can reliably fulfill its cooling function.
  • the lighting arrangement according to the invention is preferably used in a ceiling or wall construction, the plates consist of plasterboard.
  • Acoustic panels in particular made of plasterboard, are available on the market with standardized openings. These standardized openings can serve according to the invention as installation openings for the LED built-in modules. These openings are, for example, 10 mm in diameter and arranged regularly distributed over the acoustic panel at a distance of 20 mm from center to center. Further advantageous developments of the invention are described in the subclaims and can be taken from the embodiments of the invention described below.

  • the LED unit 2 consists of a printed circuit board on which at least one, not shown, white or colored light emitting light emitting diode is arranged, which is covered by an optical system 16.
  • the LED unit is brought into good thermally conductive connection with the heat sink 3, for example by means of a double-sided adhesive tape.
  • the electrical supply lines are not shown.
  • the heat sink is in plan view of the LED unit 2 in approximately rectangular shape with longitudinal sides 17 and transverse sides 18.
  • the heat sink 3 has a substantially parallelepiped shape.
  • the LED unit 2 is attached to the outside thereof, more specifically to the outside of the bottom surface 19 of the cuboid.
  • the circuit board of the LED unit 2 is also rectangular.
  • the transverse side 18 of the heat sink 3 is open over the entire height, i. it extends there a slot 20. To facilitate the guidance of the electrical lines, it is also provided that the transverse side 18 does not extend from the bottom surface 19 to the opposite end of the heat sink 3, but only a part of the transverse side, starting from said opposite end, covered. Thus, there is a further free space in which the electrical lines can be freely routed or guided by the LED unit 2.
  • FIG. 3 shows a perspective view of a holding element 5.
  • the holding element 5 is a spring formed from two spring legs 6 and a transverse web 7, which has a central recess 8 in the transverse web 7. From this recess 8 are tongues 9, which are inclined so that they are suitable to dig into a mounting hole 4.
  • the spring legs 6 are provided at their free ends in each case with a hook-like bend 12.
  • the two bends 12 are adapted to engage in the claws 13 in the heat sink 3.
  • the structurally combined arrangement of LED unit 2 and heat sink 3 is thus locked in the retaining element 5 and thus in the mounting hole 4.
  • the holding element 5 is connected to the LED unit 2 or the heat sink 3.
  • the press-in ring 10 is shown in the installed state.
  • the press-fit 10 is seated in the recess 8 of the Retaining element 5. With its outer wall presses the press-in ring against the tongues 9 and thus ensures that the tongues 9 dig into the mounting hole 4.
  • the LED unit 2 is arranged.
  • the optic 16 projects at least partially into the tubular channel formed by the press-fit ring 10.
  • the light generated by the light emitting diode (s) is radiated via this channel into the installation opening and thus into the room to be illuminated.
  • FIGS. 6 and 7 are perspective views of a lighting arrangement with LED built-in modules 1 according to the invention and a ceiling or wall construction shown with such a lighting arrangement.
  • the lighting arrangement is arranged on a plate 11, which has evenly distributed openings.
  • a plate 11 can serve as an acoustic ceiling, for example.
  • the plate 11 is mounted on tinplate profiles 21. These sheet metal profiles 21 form a previously known in the art ceiling substructure and are used to mount the entire ceiling construction on a raw ceiling.
  • the LED mounting modules 1 are aligned so that there is always a longitudinal side 17 of a first heat sink 3 next to a transverse side 18 of a second heat sink 3 and vice versa, unless it is the outermost LED built-in modules.
  • the electrical lines are usually always passed through the receiving space 14 through to the respective LED unit 2. This is also a use of the strain relief 15 in an advantageous manner possible.
  • this may have spacers 22 in addition to the holding element 5.
