Definitions

  • the invention relates to a reflector device for a lighting device specified in the preamble of claim 1. Art.
  • connection elements are electrically conductive metal parts whose outer shape is formed by means of a turning process.
  • the connection elements fulfill three main functions: first, they enable the connection of a luminous element within the reflector element, secondly they connect the luminous element with an electrical power source due to their electrical conductivity and, thirdly, they serve to fix the entire reflector device in a mounting device.
  • a reflector device according to the prior art is shown in detail in FIGS. 1 to 3 and corresponds in its construction to currently produced reflector device types.
  • the connection elements are fixed to the reflector element in that they are guided by designated mounting holes in the back of the reflector element and axially crimped from the opposite side.
  • the to Flanging necessary support of the connection elements on the outside of the rear wall is ensured by a ring formed on the circumference of the connecting elements.
  • a disadvantage of this device and this method is the fact that the connecting elements must necessarily have a ring, which in addition to its support function must additionally serve as a stabilizing element against tilting of the connecting elements within the mounting hole.
  • the production of such a connection element in one step is currently possible only with the help of turning process.
  • This has the disadvantage that the rotary parts thus obtained are not only expensive to manufacture but in particular also subject to the restriction to rotationally symmetrical outer shapes. If necessary, non-rotationally symmetrical formations can be realized in additional work steps, for example by re-milling. As a result of this, and due to the material waste inherent in turning processes, however, the production becomes more expensive.
  • a recessed web has to be introduced into the rear side of the reflector element, which is capable of accommodating the ring formed on the outer circumference of the connection element. This is necessary to ensure a flat rear surface, since otherwise the reflector device can not be fixed in a designated mounting device due to the step formed by the ring.
  • Object of the present invention is therefore to provide a device and a method of the type mentioned above, which allow a simpler, more cost-effective and reduced waste production and overcome the restriction to rotationally symmetrical outer shapes of the required connection elements.
  • the object is achieved by a reflector device for a lighting device having the features of claim 1 and a method for producing the reflector device for a lighting device having the features of claim 9.
  • the reflector device for a lighting device comprises a reflector element with at least one mounting opening on the rear side, in which an electrically conductive connecting element is arranged.
  • the mounting opening itself preferably has a circular cross-section base and is formed as a cylindrical passage through the reflector element.
  • the connecting element is structurally matched to the mounting opening, that it is not completely feasible through the mounting hole. This can be ensured, for example, by a cross section of the connection element that is widened in some regions in relation to the diameter of the mounting opening.
  • the connection element itself has below a first end region, which means for fixing the reflector device in a holding device, a third area in cross section running third with a predetermined diameter.
  • connection element is coupled after its partial arrangement within the mounting opening with the reflector element. This coupling is preferably carried out by crimping the connection element from the light emission side of the reflector element.
  • the connecting element itself serves in the context of the reflector device both for receiving a luminous element, for coupling this luminous element with an electrical power source as well as for fixing the entire reflector device in a mounting device.
  • the luminous element may be, for example, a halogen lamp
  • the mounting device may be a GU10 or GZ10 type socket.
  • a reflector element either all-glass reflectors or reflector elements with ceramic base can be used.
  • other lamp types and / or socket types are also conceivable.
  • Particularly advantageous in such a reflector device according to the invention is the fact that no more ring must be formed on the connection element used, since the previously taken over by the ring functions are realized by means of alternative embodiments of the connection elements. This opens up the possibility of cost-effective connection elements instead of as previously by means of turning process using alternative manufacturing processes in one operation even with non-rotationally symmetrical outer shapes manufacture.
  • eliminating the use of alternative manufacturing processes in the previously used turning process always accumulating material waste, which is both from the environmental as well as financial aspects of great advantage.
  • the reflector element according to the invention has a continuous wall thickness and thus has an increased stability and resistance to fracture over a conventional reflector element.
  • a particularly simple embodiment of the reflector device is obtained when the reflector element has a locking element within the mounting opening.
  • the locking element not only a passage of the connection element is prevented by the mounting hole, the locking element also prevents twisting of the connection element within the mounting hole and thus ensures during assembly for additional stability of the connection element against tilting.
  • the locking element is formed as a raised structure with respect to the inner surface of the mounting opening, it is possible in a particularly advantageous manner to use the locking element both as a support and as a twist protection for the connection element during assembly.
  • the locking element is an elongate web within the mounting opening of the reflector element trained and offers in addition to the advantages already mentioned additionally the function of a guide rail during insertion of the connecting element during assembly of the reflector device.
  • a guide rail during insertion of the connecting element during assembly of the reflector device.
  • various other geometric cross-sectional shapes such as a triangular base, for the locking element are conceivable.
  • the locking element does not have to extend along the entire inner surface height, but may also be formed only as a partial elevation, for example in the form of a hemisphere, on the inner surface.
  • connection elements are formed within a mounting opening. These are preferably spaced from each other so that the mounting opening formally has a Kimetrieoperator. Particularly advantageous is the formation of three locking elements, which are formed in cross section in the form of an equilateral triangle within the mounting hole. However, an alternative number and arrangement of locking elements is conceivable. By the one hand, enlarged contact area between the connection element and mounting hole and the other hand additional support points for the connection element a particular high stability and a fixed counter-hold are achieved during assembly of the reflector device.
  • the connecting element has at least in that region which is carried out through the mounting opening, one or more recesses, which ideally correspond to there trained locking element are formed.
  • the recesses may, for example, be slot-like openings along the surface of the connection element, whereby both the anti-rotation device within the installation opening is made possible and a simple means for supporting the connection element on the rear side of the reflector element during crimping can be realized. This eliminates the need to bring a trained against the back of the reflector element web formed in an additional process step, since the connection element no longer has to have a ring.
  • a resulting further advantage is that the back without web can have a thicker, uniform cross section, whereby additional mechanical stability is ensured.
  • a particularly stable and cost-effective device is achieved in that the connecting element has a step-shaped design, which represents a particularly simple means for supporting the connecting element on the back of the reflector element.
  • the design can be combined with additional recesses in guided through the mounting hole part of the connection element, so that all stabilizing, facilitating the installation and cost-reducing means can be realized in one component.
  • the reflector device can be coupled as part of a lighting device with an electric lighting element such as a halogen lamp, has a particularly useful arrangement two mounting holes on the back of the reflector element, wherein in each case a connection element is fixed.
  • the luminous element can not only be held in the reflector device, but simultaneously be coupled to a current source, in particular a direct current source, wherein each terminal element is connected to an electrical pole.
  • a reflector element which has a light emission side and a reverse side facing away from it. At least one mounting opening is provided on the rear side.
  • the reflector element is preferably an all-glass reflector or a ceramic reflector element.
  • the mounting opening may already be provided during the production of the reflector element or may be introduced later into the reflector element.
  • a connection element is formed, which is then inserted into the mounting opening.
  • the reflector device according to the invention is formed by coupling the connection element with the reflector element.
  • the coupling is thereby preferably realized by a crimping step, in which the end region of the connection element, which is passed through the mounting opening, projects from the light emission side of the reflector element is bent at right angles and so a non-detachable connection of the two workpieces is achieved.
  • the massive forming process for forming the connection element includes an extrusion process.
  • the extrusion process non-rotationally symmetrical, complex outer contours can be produced in one operation instead of the rotary process as hitherto.
  • the production of complex shapes can be understood as meaning a wide variety of asymmetrical configurations, such as, for example, the formation of recesses in the connection element.
  • Such a configuration also opens up the possibility of introducing further recesses into the connection element in combination with an additional method step.
  • connection element by thermal separation processes, in particular laser cutting process, additional slots are introduced into the connection element, so that the connection element is to be fastened by a detachable bayonet lock on the reflector element instead of by a non-detachable crimping step.
  • Another advantage of extrusion is that, in contrast to turning process no material waste is obtained. As a result, a significant effort and cost reduction in the manufacturing process can be achieved.
  • Suitable materials are all materials in question, which are both suitable for extrusion processes and electrically conductive, in particular So metals such as aluminum or metal alloys such as brass.
  • an additional cost reduction is achieved in the context of the method according to the invention in that the required mounting opening on the back of the reflector element does not have to be introduced during its production. Instead, the mounting opening can be introduced in a particularly preferred and cost-reducing manner by a water jet cutting method before the arrangement of the connection element in the reflector element.
  • An advantage of this procedure is also that depending on the situation assembly openings with individually adapted to the respective connection element configuration can be produced at the same time low manufacturing tolerances.
  • the different embodiments may include, for example, different locking elements or different diameters or geometries of the mounting hole. In this way, different reflector element types with different mounting hole shapes and different types of connection elements within the same process can be combined in almost any way to a variety of conceivable reflector devices.
  • a reflector device for a lighting device is shown, as is apparent to those skilled in the art as known.
  • This comprises a known reflector element 19 with a light emission side 24 and a rear side 22 into which two assembly openings 18, which are circular in cross-section, are introduced.
  • Within the mounting holes 18 are known from the prior art connection elements 6, which are connected to the reflector element.
  • Each connection element 6 has an end region 10, which is arranged outside the reflector element 19 and is configured as a function of the holding device to be used, by means of which the entire reflector device is to be fastened in a holding device (not illustrated).
  • a ring 12 is formed on the circumference of each connecting element 6, which prevents both tilting of the connecting element 6 in the mounting hole 18 and acts as a counter-stop when connecting the connecting element 6 with the reflector element 19. Due to the raised structure of the ring 12 relative to the surface of the back surface 22, it is necessary to insert a recessed land 21 into the back surface 22 of the reflector element 19 to achieve a flat surface and thereby facilitate attachment of the reflector device in the mounting device ,
  • FIG. 2 shows a connecting element 6 according to FIG. 1, which is rotationally symmetrical as a turned part.
  • a reflector device To produce a reflector device according to the prior art, it is introduced with an end region 14 into a mounting opening 18 of the reflector element 19 and connected from the light emission side 24, for example by crimping with the reflector element 19.
  • the ring 12 provided as a counterhold, bushing and tilt protection is again shown on the circumference of the connecting element 6.
  • FIG. 4 shows an exemplary embodiment of a reflector device according to the invention in a perspective rear view.
  • a reflector element 20 with a light emission side, not shown, and a rear side 22 opposite thereto has two mounting openings 26, in each of which an attachment element 8 according to the invention is arranged.
  • the end regions 10 of the connection elements 8 according to FIG. 1 and FIG. 2 lying outside the reflector element 20 are formed identically to the end regions of the known connection elements 6, depending on the holder device to be used.
  • the reflector element 20 has in this embodiment, as the reflector element 19 according to the prior art, a recessed on its rear side 22 web 21, which is not required for the realization of a reflector device according to the invention and can be omitted without replacement.
  • connection element 8 used in FIG. 4 is shown in FIG. 5 in a perspective rear view. Since the production of this connection element 8 by a material forming process such as an extrusion molding process, the restriction to rotationally symmetrical formations deleted.
  • the connection element 8 has its associated into the mounting opening 26 end portion 14 associated with a plurality of recesses 16th
  • FIG. 6 An embodiment of the reflector element 20 for a reflector device according to the invention, as shown in FIG. 4, is shown in FIG. 6 in a schematic side view.
  • the locking elements formed within the assembly openings 26 correspond with the recesses 16 of the connecting element 8 shown in FIG. 5 and, in conjunction with this, simultaneously act as an execution protection, support element and anti-rotation protection.
