Definitions

  • the present invention relates to a luminaire according to the preamble of claim 1 and an at least partially translucent cover profile according to the preamble of claim 8, wherein the cover profile is releasably secured in an opening of the lamp housing of the lamp.
  • Lamps for example, so-called slotlight lamps of the Applicant, which are used both in the ceiling installation / in as well as in suspended or pendulum manner, for example, may have a formed by a narrow elongated aluminum profile luminaire housing.
  • the luminaire housing serves to receive a light source and possibly also electronic control means.
  • the luminaire housing in this case has an opening in the desired emission direction of the luminaire. Such an opening can then remain without cover or even have a cover profile.
  • This cover profile can be, for example, a transparent body made of Plexiglas, which is detachably fastened to the aluminum profile.
  • a cover according to the US Pat. No. 6,402,349 B1 For example, to clean a flat light exit surface provided with a pyramidal superstructure, so that there is a hollow chamber profile.
  • the FR 1 303 671 A describes a film covering for the purity of jagged light guide means and the EP 0 391 287 A is directed to an operating light, which improves the depth profile of the lighting with the aid of successive lying while a cavity enclosing Fresnel lenses.
  • the use of a cover profile does not ensure that the interior of the luminaire is protected against moisture and that no light can escape from the housing laterally past the cover profile.
  • the present invention is therefore based on the object to further develop the lamp described above in such a way that it emits light over the entire width of an opening evenly without shadows or disturbing contours, and on the other hand, the interior is protected from moisture and light can only be delivered via a cover profile.
  • a luminaire and an at least partially translucent cover profile are proposed.
  • the luminaire has a luminaire housing with an opening in the emission direction and the cover profile, which is detachably secured in the opening of the luminaire housing, on.
  • the cover profile is designed as a hollow chamber profile.
  • the hollow chamber profile which is configured such that it has a light entrance and a light exit side and a hollow chamber between the two sides, now leads to the fact that the light emitted by the light source is emitted evenly on the light exit side. In addition, no shadow and disturbing contours are more visible through the hollow chamber profile.
  • the hollow chamber profile is designed to be releasably fastened by means of latching means attached to the light entry side.
  • the area of the light entry side facing away from the hollow chamber has a bearing surface for a seal at its edge and bears against the lamp housing, a seal being provided between the bearing surface and the lamp housing.
  • the lamp in which the interior is protected from moisture and dust and thus the lamp, for example, can meet the requirements for the protection IP54.
  • the light can only be delivered via the hollow chamber profile.
  • the use of a hollow chamber profile also ensures that the seal can not be recognized as a disturbing contour (dark spot).
  • the lamp housing may still have a groove for receiving the seal.
  • the latching means are designed as latching arms which extend from the surface of the light entry side facing away from the hollow chamber perpendicularly in the direction of the lamp housing and engage with the lamp housing.
  • the latching arms are mounted on the side facing away from the hollow chamber surface of the light entry side adjacent to the support surface.
  • the hollow chamber profile is formed in total or only the light entrance side or the light exit side opal or light scattering.
  • the surface of the light entry side facing the hollow chamber has a microprism structure and the surface of the light entry side remote from the hollow chamber has a smooth structure.
  • loisverändemdede may be like a plate with prismatic structure.
  • the luminaire housing can consist of a narrow elongate aluminum profile and the hollow chamber profile of two parts.
  • FIG. 1 shows the lamp 1 according to the invention in a perspective view and in cross section.
  • the luminaire 1 consists essentially of a luminaire housing 2, an at least partial translucent hollow chamber profile 3, two end faces 6 and inside the luminaire 1 of a seal 4 and a light source 5, wherein the light source 5 additionally electronic control means may be assigned.
  • the luminaire housing 2 is preferably a narrow, elongated aluminum extrusion profile.
  • the profile is essentially U-shaped, with the light being emitted via the opening of the U-shape.
  • the end faces 6 of the profile are each closed, so that the light output can be made only through the opening.
  • the inventive at least part-permeable hollow chamber profile 3 is placed that can be produced for example by injection molding or by extrusion.
  • the hollow chamber profile 3 is formed substantially cuboid, wherein the length and width of the hollow chamber profile 3 corresponds to the length and width of the opening of the lamp housing 2.
  • the hollow chamber profile 3 is located on the outer walls 7 of the lamp housing 2 and the end faces 6, whereby only the lamp housing 2, the hollow chamber profile 3 and the end faces 6 can be seen in the inventive lamp 1 from the outside.
  • the cuboid hollow chamber profile 3 has a light inlet side 14 and a light exit side 15. Between the two sides 14, 15 is a hollow chamber 13 which is closed by outer sides 16, wherein these outer sides 16 connect the light entrance side 14 with the light exit side 15, resulting in the cuboid shape of the hollow chamber profile 3 according to the invention.
  • the hollow chamber 13 facing away from surface 17 of the light inlet side 14 has at the edges circumferentially on a support surface 11 for a seal 4.
  • the support surface 11 is slightly wider than a seal. 4
  • locking arms 8 are mounted on the side facing away from the hollow chamber 13 of the light entrance side, but not completely extend to the end faces 6 of the lamp housing 2 to form the already described above support surface 11 for a seal 4 circumferentially to be able to.
  • the latching arms 8 may in this case consist of a plurality of individual latching arms, or else in each case from a continuous latching arm.
  • the hollow chamber profile 3 according to the invention is now positioned in the luminaire housing 2 in such a way that the latching arms 8 and thus also the surface 17, facing away from the hollow chamber 13, of the light inlet side 14 points inwardly into the luminaire housing 2.
  • the luminaire housing 2 has in this case in the region in which the support surface 11, the hollow chamber 13 facing away from surface 17 of the light inlet side 14, a groove 12 which is configured such that it can receive a seal 4 which then rests against the support surface 11 , Accordingly, it is also necessary, as already described above, to make the bearing surface 11 slightly wider than the seal 4, so that the part of the groove 12 projecting from the outer walls 7 of the luminous housing 2 correspondingly finds space in front of the latching arms 8.
  • the latching arms 8 which are perpendicular to the side facing away from the hollow chamber 13 17 of the light entry side 14 engage in the connection to the groove 12 in a recess provided for this purpose, whereby the latching arms 8 must be slightly longer than the seal 4 and the groove 12.
  • the latching arms 8 are also formed for locking at their ends to a V 9 opening to the center of the lamp housing 2, wherein the tip of the V 9 engages in the recess 10.
  • the height of the cuboid hollow chamber profile 3 corresponds approximately to the length of the outer walls 7 of the lamp housing 2, starting from the opening of the lamp housing 2 to the beginning of the groove 12th
  • the light entry side 14 of the hollow chamber profile 3 opal or light-scattering, whereby the above-described light uniformity is further improved.
  • This possibility is in FIG. 5 shown. It would also be conceivable that only the light exit side 15 is opal. In both embodiments, in particular the production of the hollow chamber profile 3 in the two-component injection molding process is advantageous.
  • Another optimization possibility is the use of a total of opal trained hollow chamber profile 3, as in FIG. 2 is shown.
  • microprism structure may be provided.
  • the microprisms are preferably on the hollow chamber 13 facing surface 18 of the light entrance side 14 is formed, as shown in FIG FIG. 3 will be shown.
  • a plate 20 is additionally housed in the hollow chamber 13, which has a prismatic structure and thus an alternative to the in FIG. 3 shown hollow chamber profile 3 is.
  • other light-modifying means such as a color filter or micro-grid, could be arranged in the hollow chamber 13.
  • the hollow chamber 13 facing away from surface 19 of the light exit side 15, however, is preferably always smooth, since this is the preparation of Saugnäpfen possible to remove the hollow chamber profile 3 from the lamp housing 2 again. This is usually the only way to get into the interior of the lamp 1. If, for example, microprisms were to be formed on the underside of the hollow chamber profile 3, the application of the suction cups would not be possible and the hollow chamber profile 3 could only be removed by means of specially designed tools.
  • inventive hollow chamber profile 3 is integrally formed.
  • this does not mean that such a hollow chamber profile could not consist of two parts, it would be conceivable that the light exit side is formed by a second part which is latched with the light inlet side or inserted into this.
  • the shape of the lamp or the lamp housing and the hollow chamber profile does not necessarily have to have a narrow elongated profile.
  • a round luminaire housing could also be used, for which purpose the hollow chamber profile would also have to be correspondingly round.
