Definitions

  • the invention relates to a luminaire component, in particular a cover for a light source, such as an optic, for fixing on a counter bearing, in particular a retaining plate, retaining profile or heat sink, with a fastening element by means of which the lamp component can be fastened to the counter bearing.
  • a luminaire component in particular a cover for a light source, such as an optic, for fixing on a counter bearing, in particular a retaining plate, retaining profile or heat sink, with a fastening element by means of which the lamp component can be fastened to the counter bearing.
  • Luminaire components of the generic type in particular as a cover for a light source in the form of a translucent plastic cover which optically influences the distribution of the light and which are commonly referred to as optics, are for example made of WO2014 / 184422A1 known.
  • plastics such as polycarbonate or polymethyl methacrylate are used for such covers. Both plastics can be produced in a transparent, translucent manner and are ideally suited for incorporating optical elements into the respective cover using the injection-molding process. By means of these optical elements it is possible to direct the light emanating from a light source in its distribution in the desired manner. This is particularly necessary with LED light sources.
  • the object of the invention is therefore to create alternative fastening means for generic lighting components, in particular covers for light sources, i.e. in particular optically effective covers, which enable simplified production and in particular meet the material properties of the two plastics described above.
  • the fastening element is a latching element
  • the latching element forms a latching arm, which the latching arm arises from the luminaire component in the insertion direction and a free end in the insertion direction and has an end connected to the luminaire component
  • the latching element has a first, wedge-shaped latching hook, the wedge tip of the first latching hook pointing in the direction of the free end of the latching element, the back surface facing away from the wedge tip and close to the luminaire component serving as a holding surface and forming the undercut of the first latching hook, at least one side surface of the first locking hook at an angle to the insertion direction is issued
  • the first latching hook is pivotably resiliently mounted in the latching element, the pivot axis of the first latching hook is remote from the lighting component and is located near the free end of the remaining element. The pivot axis is also located in the area of the wedge tip of the first locking hook.
  • the invention uses latching elements in the form of latching hooks for the first time to fix said lamp components, in particular optical covers for light sources, this being in particular circuit boards with one or more attached LEDs as a light-emitting source. This makes the assembly much easier, since the placement on the counter bearing and the attachment to the counter bearing are one and the same work step.
  • latching elements in particular the latching hooks arranged on the latching arm, that they engage a suitable holding contour, for example an opening, for attachment to the counter bearing and, for this purpose, perform an evasive movement around the holding contour.
  • the latching element must be able to be resiliently deformed in order to hook onto the retaining contour. Therefore, the locking arm is usually deformed around an axis and practically performs a pivoting movement around this axis.
  • the locking element according to the invention is provided with a locking hook, the pivot axis of which is arranged remote from the lamp component.
  • the latching hook executes a pivoting movement on a circular line from the luminaire component, the center of which roughly coincides with the tip of the wedge.
  • This special position of the pivot axis of the first latching hook allows the latching element dimensions to be adapted to the tough elastic polycarbonate on the one hand and to the rather brittle polymethyl methacrylate on the other hand.
  • a luminaire component is particularly preferred which is characterized in that the latching arm has an in particular ring-like recess closed with a web remote from the luminaire component, the first council hook is arranged within the recess and connected to the web, in particular when the pivot axis of the first latching hook is in the area of the Connection of the first latching hook lies on the web, the web in particular forming the pivot axis of the first latching hook.
  • the storage of the latching hook in the recess described above and its connection to the latching arm allows the tension loads on the plastic during the overtravel movement to be optimally distributed in order to engage in the retaining contour of the counter-bearing.
  • the locking arm is designed to be resiliently pivotable about a pivot axis close to the lamp component, the pivoting movement required for the overtravel can be distributed over two different material areas of the locking element, so that the tension loads are divided between two pivoting or bending areas.
  • This is a further design feature in order to avoid permanent deformations in the case of viscoplastic polycarbonate by exceeding the resilience elasticity and, when using polymethyl methacrylate, to prevent fractures due to excessive stress.
  • the locking element has a second locking hook, the wedge tip of the second locking hook also pointing in the direction of the free end of the locking element, that of the wedge tip
  • the back surface facing away and close to the luminaire component also serves as a holding surface and forms the undercut of the second snap-in hook
  • at least one side surface of the second snap-in hook is also at an angle to the insertion direction, but in the opposite direction in relation to the opening angle of the first snap-in hook, so that the second snap-in hook is opposite to the first snap-in hook is issued
  • the second latching hook is also pivotably resiliently mounted on the latching element, but the pivot axis of the second latching hook is located close to the lamp component and away from the free end of the latching element. The pivot axis is therefore remote from the wedge tip or close to the holding surface, in particular between the holding surface of the second latching hook and the lamp component.
  • one and the same cover can initially be adapted to retaining contours that differ from one another in two counter bearings that are at least different from the retaining contours.
  • One and the same cover can thus be used both for the counter-bearing of the first type and for the counter-bearing of the second type.
  • the second latching hook is arranged on the arm of the latching element outside the recess.
  • the web is part of the free end of the locking arm, in particular when the web forms the wedge tip of the second and in particular also of the first locking hook.
  • the luminaire component forms centering contours close to the locking element, which interact with a centering contour of the counter-bearing in order to arrange the luminaire component in the correct position on the counter-bearing.
  • the support structures make it possible to also fix the light source to be covered, in particular the board provided with LEDs, on the counter bearing when the cover is placed and fixed, so that a separate fastening of the board is not necessary.
  • the board which is fixed on the counter-bearing before the cover is placed on the counter-bearing, experiences additional contact pressure on the counter-bearing through the support structures of the luminaire component. In this way, especially with larger board dimensions, an even pressure on the counter bearing is guaranteed over the entire board surface. Since the counter bearing is often a heat sink, this optimizes the dissipation of heat from the board to the heat sink.
  • one of the two locking hooks has a function of anchoring the lamp component in the counter bearing by engaging behind the counter bearing, whereas the other locking hook secures the anchoring function by the locking element being able to support against a loosening movement on the counter bearing.
  • the two latching hooks are not only used to fix one and the same optics to either one of two differently designed counter bearings.
  • the locking hook that is not used for fastening is used for Stabilization or support of the latching connection is used and thus improves the fixing of the luminaire component in the case of the latching connection which tends to release loads.
  • the holding surface of the first latching hook has a stepped, curved or inclined surface and to be able to compensate for tolerances of the material thickness of the counter bearing.
  • pivot axis of the locking arm and the pivot axis of the second locking hook coincide in their position.
  • a counter-bearing also contributes to the solution of the invention, which is initially characterized in that the counter-bearing has a passage contour for the locking element, the width of which is smaller than the width of the locking element defined by the undercuts of the first and second locking hooks.
  • the counter-bearing forms a holding contour that cooperates with one of the locking hooks to fix the lamp component on the counter-bearing and that the counter-bearing forms a support contour that cooperates with the other locking hook in order to release a loosening movement of the lamp component on the counter-bearing To block locking element.
  • the lamp component 11 shown is an optically effective cover made of a transparent plastic such as polycarbonate or polymethyl methacrylate. It has a light exit wall 12 into which the viewer can see the underside pointing in the direction of the light source (not shown) Figure 1 is facing.
  • the light exit wall 12 initially carries optically effective elements 13 on its underside, which are made from the luminaire component material itself are trained. These are, for example, divergent or convergent lenses with a receiving cup 14, which the LED 15 in the Figures 2 and 4th LED board shown overlapped. Retaining pins 17 are used to hold the LED circuit board 16 between them and a counter bearing and to ensure that the LED circuit board 16 rests evenly on the counter bearing. In this way, a good heat transfer between the plate 16 and the counter bearing is guaranteed.
  • Centering pins 18 position the circuit board 16 relative to the optical elements 13 in order to ensure correct light guidance through the optical elements 13.
  • Side walls 19 of the optically effective cover 11 have latching elements, provided overall with the reference number 20, with a latching arm 21 which carries a first latching hook 22 and a second latching hook 23.
  • the side walls 19 form centering contours 24. These engage in the retaining contour of a counter-bearing in a manner not described in detail in order to position the cover 11 in the correct position relative to the counter-bearing.
  • the representation of the Figure 7 an end view of the locking element 20, shows its features in detail.
  • the latching element 20 has a latching arm 21 which arises from the lamp component in an insertion direction X and has a free end, not designated in more detail, and an end connected to the lamp component 11.
  • the latching arm 21 carries a first latching hook 22 which is approximately wedge-shaped.
  • the first wedge tip 26 of the first locking hook points in the direction of the free end of the locking arm, whereas the first back surface 27 of the first locking hook 22 facing away from the wedge tip points in the direction of the cover 11.
  • the first back surface 27 serves, as it were, as a holding surface for fastening the lamp component 11 to a counter bearing.
  • the latching hook also has a first side surface 28 which extends from the first wedge tip 26 to the first back surface 27 and forms an angle with the direction of insertion. This first side face is raised to the side with respect to the latching arm, so that the first latching hook 22 is raised in a first direction with respect to the latching arm 21.
  • the first back surface 27 or the first holding surface 27 has a compensating structure in order to be able to compensate for different material thicknesses of a counter bearing.
  • the back surface is of a stepped design and, starting from the latching arm, drops off in the deployment direction of the first latching hook 22.
  • this compensation structure can consist of a correspondingly sloping inclined surface or a curved surface.
  • the latching arm 21 then carries a second latching hook 23 with a second wedge tip 30 which points in the direction of the free end of the latching arm 21 or here in the exemplary embodiment forms the free end of the latching arm 21. Facing away from the second wedge tip 30, the second latching hook 23 forms a second back surface 31 which also faces the cover 11.
  • a second side surface 32 of the wedge-shaped second locking hook 23 extends from the second wedge tip 30 to the second back surface 31 and is inclined with regard to the insertion direction X or the longitudinal extension of the locking arm 21, so it also forms an angle with the insertion direction.

In other words, the exhibition of the first locking hook 22 and the second locking hook 23 is opposite.
  • FIG 6 shows a partial side view of the cover 11 showing the latching element 20.
  • the latching arm 21 has a recess 33 which is approximately ring-shaped, the ring contour here being approximately rectangular.
  • the recess 33 is closed on its side remote from the luminaire component by an annular web 34.
  • the recess 33 is closed on the side facing away from the annular web 34 by the side wall 19 of the cover 11.
  • the first locking hook 22 is arranged on the ring web 34, so that the ring web 34 forms, as it were, the wedge tip 26 of the first locking hook 22.

  • the annular web 34 has a material weakening zone in the area of the connection of the first latching hook 22.
  • the first latching hook 22 is arranged on the latching arm 21 or in particular on its annular web 34 so as to be pivotable in a resilient manner. It can be pivoted back in the direction of the latching arm 21 by a corresponding force, for example in the event of an overstroke over a retaining contour of a counter bearing.
  • the pivot axis lies in the connection area of the ring web 34 and the first locking hook 22, that is to say in the area of the wedge tip 26 of the first locking hook 22 or, in a preferred embodiment, is formed by the ring web 34.

  • the second latching hook 23 which, depending on the perspective, either also has a recess 33 or is available in duplicate on both sides of the first latching hook 22, is also designed to be resiliently pivotable in order to allow an overtravel movement when engaging the retaining contour of a counter bearing. Its pivot axis is to be found approximately in the connection area of the latching arm 21 on the lamp component 11 or its side wall 19 or corresponds to a pivot axis of the latching arm 21, which carries out the overtravel movement of the second latching hook 23 when it engages the retaining contour of a counter bearing.
  • Figure 4 shows the arrangement of the cover 11 according to the invention on a counter bearing 40 of the first embodiment, hereinafter also referred to as the first counter bearing 40.
  • This is a strongly profiled component on which a circuit board 16 with an LED 15 is arranged.

  • the receiving cups 14 of the optical elements 13 receive the LEDs 15.
  • the first counter-bearing 40 forms grip strips 41 which protrude approximately parallel to the board or parallel to the light exit wall, which in the Groove space 42 of a profile groove 43 protrude into it.
  • the groove wall opposite the grip strip 41 is designed as a support wall 44.
  • the profile groove 43 with the grip strip 41, groove space 42 and support wall 44 together forms the retaining contour 45 for securing the cover 11 on the first counter bearing 40.
  • FIG. 5 The enlarged section of the section B shown here shows that a passage 46 remains between the grip strip 41 and the support wall 44, the width of which corresponds to the second latching hook 23.
  • the latching hook 23 In order to reach behind the grip strip 41, however, the latching hook 23 must pivot outwards in the direction of the support wall 44 in order to carry out an overtravel movement over the grip strip 41. In this case, it pivots about a pivot axis, not designated in any more detail, close to the side wall 19.
  • the first latching hook 22 is supported on the support wall 44. In order to execute the overtravel movement, it must pivot in the opposite direction to the first locking hook in the direction of the locking arm 21.
  • the first latching hook 22 which has been pivoted out again, is supported on the support wall 44.
  • the second latching hook 23 is held in its fixing or fastening latching position, whereas the first latching hook 22 acts to secure the latching position and is supported on the support wall 44.
  • Figure 2 shows the fixing of the cover 11 on a second counter bearing 50 of a different design.
  • This is an essentially flat component, for example a sheet metal, on which the circuit board 16 with the LEDs 15 arranged thereon rests and is covered by the light component 11.
  • the counter-bearing 50 has an opening 51, the edges of which form the retaining contour and here interact with the first latching hook 22 for fixing the component 11 on the counter-bearing 50.
  • the detailed representation according to section A in Figure 2 shows that the width of the opening is roughly the same as the width of the corresponds to the first latching element 22 and the first latching element 22 must be pivoted in the direction of the latching arm 20 to pass through the opening 51.
  • the first latching hook 22 pivots about a pivot axis that is remote from the lighting component and is located in the region of the free end of the latching arm 21.
  • the locking arm 21 can be moved about a pivot axis close to the lamp component, so that the total overtravel movement for inserting the locking element 20 into the opening 51 between the locking arm 21 and the first locking hook 22 can be divided. In this way, the necessary forces can be distributed over the locking element 20 in order to avoid overload moments in individual areas.
  • Figure 3 also shows the advantage of the compensating contour of the first latching hook 22. Due to its stepped contour, it can engage behind different sheet metal thicknesses or counter-bearing thicknesses, so that a secure position of the cover 11 on the second counter-bearing 50 is ensured.
  • the unused latching hook 23, in this case the second latching hook 23, acts to prevent loosening. If and to the extent that tensile forces or releasing forces act on the luminaire component 11, the latching element is supported securely on the counter bearing 50 via the first latching hook with its pivot axis remote from the luminaire component. An imaginary releasing movement of the cover 11 away from the counter bearing 50 does not lead to the pivoting of the first latching hook 22, for example, but to a further pivoting out and thus wedging. In this way, the axial position of the first latching element remote from the luminaire component is of considerable advantage in terms of securing the fastening.
