Definitions

  • the invention relates to a spotlight with a bulb socket and a reflector, which has an opening located in the main illumination direction, which is covered by a transparent disc, wherein an edge region of the reflector between the transparent disc and a parallel extending, having an opening for the reflector Fixing disc is arranged and wherein the relative position between the fixing disc and transparent disc is fixed by a frame.
  • An object of the invention is to develop a radiator of the type mentioned in such a way that the reflector, the transparent disc and / or the fixing disc solve in the simplest possible way from the radiator or by said frame and replace it if necessary let, where also the manufacturing cost of the spotlight to be lowered.
  • this object is achieved by a radiator according to claim 1 and in particular in that the frame is designed so flexible that fixing disc and / or transparent disc are solvable solely by a deformation of the frame of this.
  • the inventive flexible design of the frame which fixes the fixing disc relative to the transparent disc together with the pinched between the discs reflector is achieved in an advantageous manner that in addition to the already existing elements of the frame, the transparent disc, the fixing plate and the reflector none additional components are needed to connect said elements together. Rather, the frame itself holds the fixing disc and the transparent disc together so that they can not or only slightly move relative to each other.
  • the frame By deformation of the frame, however, it is possible according to the invention to release the fixing disk, the transparent disk or both disks from the frame, so that the reflector clamped between the fixing disk and the transparent disk is released by this process.
  • the said deformation of the frame accordingly causes molded onto the frame and in particular integrally formed with it holding elements are moved relative to the disc to be solved so that the respective disc is released.
  • a radiator according to the invention in certain applications there is a need to exchange the reflector for another reflector, for example with a modified emission angle.
  • the fixing disc which effects, for example, a light-scattering effect, in order to produce a different illumination effect here, for example by means of a corresponding coloring of the fixing disc.
  • the transparent pane for example, with a color filter so as to be able to realize a respectively desired color with regard to the main illumination caused by the reflector opening. All these exchanges are inventively fast and easy accomplished.
  • the inventive principle can be realized particularly cost-effective, since only the material used for the flexible frame selected accordingly and the frame must be provided at the same time with cost-formable thereto retaining elements for the fixing disc and the transparent disc.
  • optional frame, transparent pane, reflector and fixing disk can be exchanged, which is achieved when the four elements mentioned above are each designed to be detachable from one another.
  • the frame can be formed in the main illumination direction with a particular circumferential, inwardly projecting collar, which forms a stop surface for the edge region of the transparent pane.
  • the transparent pane is located in the main illumination direction, usually behind the fixing plate and behind the reflector, so that they effectively forming the foremost element of the spotlight. Now, when the frame in the main illumination direction is provided with said collar, the transparent disc abuts against it and is thus prevented from moving in the main illumination direction.
  • the frame is provided on its inside with at least two projections which serve as holding elements for the fixing disc.
  • These projections which can be easily formed integrally with the frame during its manufacture, come to lie with mounted radiator against the main illumination direction directly behind the fixing disc, so that they are suitable for the unit of fixing disc, reflector and transparent disc between the above-mentioned Collar and the projections to keep in a defined position.
  • the fixing disc is prevented by the projections from moving counter to the main illumination direction.
  • the projections on their side facing away from the collar of the frame can be provided with a slope.
  • the flexible frame is then pressed outward over the bevels in the region of the projections, so that both disks can be easily inserted into the frame.
  • the frame springs back to its original position due to its elasticity, so that the projections snap over the fixing disc and fix them together with the transparent disc between the collar and the projections.
  • the frame is rectangular or square, in which case on each side of the frame, in particular centrally, a projection is provided.
  • a projection is provided on each side of the frame. The provision of a projection on each side of the frame ensures that it is practically torsion-resistant and thus particularly stable when the transparent pane and fixing disk are inserted. This stabilizing effect comes into play particularly when the transparent pane and / or the fixing disk are made of a non-flexible, rigid material, for example of glass.
  • the fixing disk is designed as a diffuser having light-scattering properties.
  • a portion of the amount of light supplied by a lamp located in the reflector can escape from the rear-side open reflector, counter to the main illumination direction, and be directed from above onto the fixing disk by reflection.
  • the fixing washer then appears diffusely bright, whereby ultimately a diffuse light exit region is defined, which surrounds the reflector opening located in the main illumination direction.
  • the frame according to the invention is preferably made of thermally resistant plastic, which is particularly resistant to heat up to temperatures of 120 ° C and more. This reliably prevents the frame from deforming due to the effects of heat.
  • the frame can also be made of metal, in particular of spring or stainless steel.
  • the projections for holding the fixing plate already explained above may be, for example consist of tabs that are punched out of the metal and bent towards the frame inside. By means of such bending, it is also possible to automatically generate the already explained bevels, which facilitate insertion of the transparent pane and the fixing plate into the frame.
  • the radiator according to the invention can be embodied as a recessed spotlight mounted in a housing or as a downlight, in which the frame holding the transparent pane, the reflector and the fixing disk can in turn be fastened in a housing-side frame mount.
  • the frame is made detachable from the frame holder to allow in this way, for example, a simple change of the bulb.
  • the frame is coupled to at least one flexible retaining element, which further connects the frame in its released from the frame mount position with the housing. This prevents a fitter from having to handle a separate component, namely the frame with the elements located therein, when replacing the luminous means. Rather, the frame can be released after loosening from the housing by the fitter, as he continues to hang on the flexible holding element on the housing. At the end of the assembly process, the frame hanging on the housing can simply be grasped again and connected to the housing.
  • two flexible retaining elements are attached to one side of the frame, so that it can not rotate relative to the housing about a vertical axis.
  • the subsequent example of a lamp changes assembly process is facilitated because the frame already hangs in a largely correct position on the housing and accordingly can not be misaligned relative to the housing by the fitter during assembly.
  • the holding elements are formed integrally with the frame, wherein the frame can be formed in particular as a plastic injection-molded part.
  • frame, holding elements and the existing on the inside of the frame projections by means of a single injection process can be produced in a simple manner.
  • the holding elements are no longer visible when the frame is mounted, they can be inserted with their remote from the frame area during assembly into the housing. In a disassembly, however, the retaining elements are pulled out of the housing, but they are fixed in their final position in the housing so that they can not move completely out of the housing.
  • Fig. 1 to 3 show a housing 10 of a downlight according to the invention, with with Fig. 3 apparent and in Fig. 1 for reasons of clarity not shown holding means 12 in a ceiling element 14 (FIG. Fig. 1 ) is fixed.
  • a lamp holder 16 is mounted centrally on the housing bottom, in which a light source 18 is inserted.
  • the edge region 20 of the housing opening is detachably coupled to a frame 22, which has a substantially square shape and which is provided on its side facing away from the housing 10 edge region with an inwardly projecting, circumferential collar 24.
  • a transparent disc 26 which has the shape of a square and has no openings, so that it can serve for the dust-tight completion of the housing 10.
  • a dome-shaped reflector 28 On the housing inner side 10 facing surface of the transparent plate 26 is centrally placed a dome-shaped reflector 28, which is located in the main illumination direction large reflector opening and located opposite to the main illumination direction, rear smaller Opening has. Due to the smaller opening, the illuminant 18 projects from the illuminant mount 16 into the interior of the reflector 28, so that the actual photogenerating element 30 of the illuminant 18 is located within the reflector 28.
  • the dome-shaped reflector 28 is provided in the region of its located in the main illumination direction large opening with an outwardly facing, circumferential collar 32 which rests flat on an annular portion of the transparent plate 26.
  • the outer contour of the outer contour of the transparent plate 26 corresponds, but which is provided with a central, circular recess for the reflector 28, so that the reflector 28 - with Exception of the collar 32 - can be inserted through this recess therethrough.
  • the collar 32 of the reflector 28 comes to lie between the transparent plate 26 and the inner edge region of the fixing disc 34.
  • the fixing plate 34 in turn is now in turn fixed by four projections 36 in their position, which are located respectively on the inside of the frame 22.
  • a projection 36 is provided centrally on each inner frame side.
  • the projections 36 are provided on their side facing away from the collar 24 of the frame 22 with a the introduction of the fixing plate 34 in the frame 22 facilitating bevel.
  • two tab-shaped, flexible retaining elements 40 are mounted, which extend perpendicularly away from the frame side 38.
  • the holding elements 40 At its end facing away from the frame side 38, the holding elements 40 each have a longitudinal slot 42 (FIG. Fig. 4 ) and two outwardly facing, hook-shaped elements 44, which serve to anchor the holding elements 40 in the housing 10.
  • the frame 22 in turn is by means of a snap connection 46 ( Fig. 2 ) releasably latched in the housing 10.
  • the snap connection 46 is released, so that the frame 22 can be moved away from the housing 10.
  • the frame is still by the holding elements 40, which can be pulled out of the housing 10 in this case until the hook-shaped elements 44 block further movement, fixed so that the fitter does not have to place the frame 22 as a separate component or hold it in his hand.
  • the frame 22 are released by the fitter so that he has both hands available to change the bulb 18.
  • the retaining elements 40 are pushed back into the housing, the frame relative to its position according to the Fig. 2 and 3 pivoted upwards by about 90 ° and then locked in the housing 10 via the snap connection 46.
  • the frame 22 is achieved in the manner already explained by the housing 10 according to the invention. Following this, then all four framed pages in the direction of in Fig. 3 drawn arrows are pressed slightly outward, so that the projections 36 no longer come to rest over the fixing disc 34 and the fixing plate 34 is finally released. A movement of the frame sides in the direction of arrow is possible because the frame 22 according to the invention flexible, optionally also stretchable, is executed.
  • the frame 22 can only be bent, but not stretched, it is necessary to dimension the transparent disk 26 and the fixing disk 34 such that a certain gap remains between these disks 26, 34 and the inside of the frame, which then causes movement of the frame sides in the direction of arrow according to Fig. 3 allows.
  • the fixing washer 34 After the fixing washer 34 has been released in the manner described, it can be removed from the frame 22 so that the reflector 28, whose collar 32 is no longer fixed, can be removed. Also, the transparent plate 26 can be removed from the frame 22, when the frame sides according to Fig. 3 be moved in the direction of the arrow.
