Definitions

  • the invention relates to a lamp according to the preamble of claim 1.
  • the invention also relates to a equipped with at least one such luminaire wall or ceiling made of concrete.
  • the invention is based on a luminaire with LEDs as the light source.
  • the invention is further based on a luminaire which is intended and suitable for fixing to or in a concrete ceiling or wall, in particular in a niche of the ceiling or the wall.
  • WO 2009/129232 discloses the preamble of claim 1.
  • the invention is therefore based on the task of providing a luminaire of the type specified in the introduction with improved dissipation of the heat.
  • a lighting system consisting of the actual lamp and an associated support for this lamp, which ensures a technically very simple and above all effective dissipation of the votes by the LEDs heat.
  • the basic idea with this lighting system is that the heat is introduced into the concrete of the ceiling or the wall to which the luminaire is attached. The advantage is therefore that the resulting heat is absorbed by the concrete. This has very good heat transfer properties and beyond due to the existing mass a very high heat absorption capacity. This heat dissipation into a concrete floor or a concrete wall thus has the advantage that it is possible to dispense with other cooling devices, in particular heat sinks.
  • this heat dissipation is solved in such a way that the ceiling or the wall is provided with a heat-conducting carrier made of metal.
  • This metal carrier has the task to initiate the heat given to him in the concrete.
  • the lamp is designed so that a heat flow between the place of formation of heat in the region of the LED's and the metal support is ensured. This can be done constructively in a variety of ways.
  • the carrier be cast during the casting of the ceiling or the wall with in the concrete and so completely or at least partially embedded in the concrete. This means that in the construction of the building already appropriate carriers are integrated into the concrete, where then LED lights are to be attached. In this way, it is possible in a technically simple manner to realize the above-described lighting system with the appropriate heat dissipation structurally.
  • the ceiling or the wall with a corresponding metal support. It is then necessary that the corresponding support is attached to the ceiling or wall so that a Heat flow between this carrier and the concrete can arise.
  • a depression or opening can be made in the concrete.
  • the carrier can be positioned and optionally also firmly connected to the concrete.
  • the depression or opening can be filled with a suitable, curable composition, so that subsequently the support is completely or at least partially embedded in this composition. Since the cured mass can produce a sufficient fixation for the carrier, a separate attachment of the support to the concrete is not essential, but may be advantageous at least for the assembly.
  • the mass may be a putty or a casting.
  • the mass may be a mineral mass or a plastic mass.
  • the mass may be concrete or mortar or plaster or a mineral adhesive.
  • the carrier may be a T-profile, in particular aluminum.
  • a heat-conducting body is provided, in particular made of metal, which produces the thermal bridge between the place of formation of the heat and the metal support as part of the concrete floor or concrete wall.
  • a so-called heat pipe can be provided according to another development.
  • a heat pipe as a heat exchanger.
  • the heat of vaporization of a substance with a high heat flux is used.
  • the lamp is installed in a niche of the wall or the ceiling.
  • the heat dissipation system according to the invention is very effective in the concrete. Because a conventional heat sink Can not work in a niche installation, as the LED light heats up the available cavity. As soon as the temperature of the surrounding air corresponds to that of the heat sink, cooling effect is no longer present.
  • a cooling device for the LED's can be provided for heat transfer between the lamp body and the carrier.
  • a cooling device may comprise a heat sink with cooling fins.
  • the heat-conducting connection between the lamp body and the carrier forms a cooling device for the LED's.
  • the concrete thermal bridge serves as a cooling device, which is particularly inexpensive.
  • a fastening device may be provided for attaching the lamp to or in the ceiling or the wall, which facilitates the installation of the lamp on the wall or ceiling.
  • this attachment means may have a heat transfer on the carrier attachable mounting plate, whereby a particularly effective heat input into the carrier can be realized.
  • the lamp body may have a heat sink, which is heat-transmitting connected to the LED's and is integrated into the heat-conducting connection from the lamp body to the carrier.
  • a heat sink which is heat-transmitting connected to the LED's and is integrated into the heat-conducting connection from the lamp body to the carrier.
  • a ceiling or wall according to the invention comprises at least one luminaire of the type described above and attached thereto and consists of concrete at least in the region of the respective luminaire.
  • the luminaire 1 of a lighting system has a luminaire body 2 with LED's 3.
  • This lamp body 2 is also secured by means of elongated metallic body 4 in the form of metal rods on the underside of a mounting plate 5 made of metal.
  • a so-called heat pipe 6 is provided.
  • the LED's 3 are taken in a heat sink 10, which forms part of the lamp body 2 or is inserted into this.
  • the metallic body 4 and / or the heat pipe 6 is heat-transfer connected to this heat sink, in particular attached thereto.
  • the lighting system further comprises a support 7 for fixing the lamp 1 to a wall 8 or ceiling 8 made of concrete 11.
  • This carrier 7 is through a T-profile formed of aluminum and poured into the concrete 11 of the wall or ceiling 8.
  • the above-described mounting plate 5 of the lamp 1 is attached to the underside.
  • the carrier 7 is laterally and embedded in a remote from the lamp body 2 area in the concrete 11.
  • the carrier 7 is embedded exclusively in the concrete 11.
  • Such an embodiment can be realized, for example, by attaching the carrier 7 already during the production of the wall or ceiling 8, that is to say pouring in the carrier 7 during the casting of the concrete 11.
  • a depression 12 or opening 12 can be introduced into the concrete 11.
  • the carrier 7 can then be positioned.
  • the carrier 7 in the opening 12 can be firmly connected to the concrete 11, for example by means of a screw (not shown).
  • the depression or opening 12 can be filled with a suitable hardenable mass 13, so that subsequently the carrier 7 is at least partially embedded in this mass 13.
  • the carrier is embedded without contact to the concrete 11 exclusively in the mass 13.
  • the mass 13 may be a putty or a casting.
  • the mass 13 may be a mineral mass or a plastic mass.
  • the mass 13 may be concrete or mortar or gypsum or a mineral adhesive.
