Definitions

  • the invention relates to a signal or vehicle lamp with an incandescent lamp which can be connected to a carrier, contacts of the incandescent lamp being connected to contacts of the carrier, and with mating surfaces which are associated with one another and which on the one hand on one surface of the carrier and on the other on a counter surface are arranged to only allow the use of light bulbs of a certain type.
  • tolerances of incandescent lamps and the light-guiding means, such as reflectors and prisms, which always result in mass production, can add up unhappily in one direction, so that the light distribution of such luminaires can deviate unpleasantly from the desired ideal.
  • incandescent lamps and reflector are firmly connected to each other in a unit and if the incandescent lamp fails, the entire unit is replaced. This is already practiced to a large extent in the USA by the so-called "SEALED BEAM” lamps.
  • SESEL BEAM so-called "SEALED BEAM” lamps.
  • the advantage is that a single manufacturer is responsible for compliance with the lighting values of such a unit, since the incandescent lamp and reflector come from a single source and can be completely checked for compliance with the required values after manufacture. In the case of such units, too, as with the incandescent lamps, confusion is possible, and the effects which endanger traffic can be even greater, since the reflector may also have incorrect values.
  • AT-PS 141 978 has already described a mounting and contact arrangement for electric light bulbs.
  • fitting surfaces are provided on the multi-surface, pluggable insulating parts of the bulb socket and the lamp holder, which only allow the use of certain types of bulbs in the associated sockets.
  • the differentiation options with incandescent lamp bases and sockets or fitting surfaces attached to them are only limited and are not sufficient to be able to make the distinctions necessary in practice.
  • incandescent lamps with special bases and mating surfaces can no longer be justified in the age of total standardization and mass production prices are produced because the highly automated systems would have to be stopped and converted for incandescent lamps with different electrical data.
  • CH-PS 1 92 56 describes a series of connection contacts with pins of different strengths on one and matching recesses on the other contact parts. Connection contacts designed in this way can also be used with incandescent lamps in order to avoid confusing lamps with different electrical values. Even with connection contacts designed in this way, not all the necessary distinctions can be made, the high production costs already mentioned also occurring here.
  • the invention is therefore based on the principles of creating a signal and vehicle lamp of the type mentioned at the outset, which can be produced with little effort using commercially available incandescent lamps and can be connected in a simple manner only to a carrier of a certain type.
  • the signal or vehicle light should also be operationally reliable and able to meet operational requirements in all applications.
  • the incandescent lamp is directly or indirectly connected to a fitting piece which carries the counter surface with the fitting surfaces, and that the fitting piece can be plugged onto the carrier.
  • the signal and vehicle light according to the invention can be produced in a simple manner and enables the use of a commercially available incandescent lamp due to the fitting.
  • the counter surface with mating surfaces necessary to avoid confusion or the use of incandescent lamps of a certain type is located on the mating piece.
  • Incandescent lamps with an identical outer structure, in particular with the same base, but with different electrical or lighting values, can be used by the manufacturer of the luminaire in differently designed fitting pieces, so that when the luminaire is plugged onto the correspondingly designed carrier, there is no longer any confusion possible are. There are therefore no need for incandescent lamps with special bases and associated special sockets, but standard incandescent lamps which are commercially available and which can be produced inexpensively in large numbers.
  • the fitting piece which can be plugged onto the carrier in a simple manner and which carries the counter surface with the fitting surfaces is without any special effort producible, with an almost unlimited number of possibilities for the arrangement and / or formation of the mating surfaces.
  • the adapter with the counter surface and the adapter surfaces arranged on it thus forms, together with the carrier and the adapter surfaces arranged on them, a key system which is assigned to a particular type of incandescent lamp and prevents confusion.
  • the adapter is preferably essentially designed as a plate, on the front of which a socket or other means for receiving the incandescent lamp are arranged and on the rear or side parts of which the adapter surfaces are arranged.
  • the assigned surface of the carrier with the mating surfaces is also designed in this case as an essentially flat surface. Such a fitting or such a carrier can also be produced in large numbers without particular difficulty and with little effort.
  • the fitting piece is combined in a single structural unit together with an at least partially transparent cover cap of the incandescent lamp and the light-controlling means (such as reflectors and prisms).
  • the light-controlling means such as reflectors and prisms.
  • the parts mentioned are firmly connected to one another, for example by welding or gluing them together, so that if the bulb fails, not only the bulb alone, but the entire assembly is replaced and a complete new assembly is attached to the carrier. Due to the mating surfaces of the mating piece or carrier, the plugging in of an incorrect structural unit, which therefore contains an incandescent lamp with different electrical or lighting values, is prevented.
  • the key system can also make a distinction in this respect. It is therefore of particular importance that, depending on the design of the structural unit mentioned, the adapter with the adapter surfaces is designed differently.
  • Such signal or vehicle lights combined into a complete structural unit can therefore also be distinguished from one another if they are equipped with completely identical incandescent lamps. For example, a red motor vehicle tail light with a 5 watt bulb for 12 volts can be distinguished from a yellow flashing light, which also contains a 5 watt bulb for 12 volts.
  • a red tail lamp can never be erroneously attached to the place or support for a yellow flashing light or vice versa. It is also of particular importance that the correct angular position of the structural unit can also be specified with the key system consisting of a fitting piece and carrier with correspondingly designed fitting surfaces. If, for example, the reflector has lateral slots through which the light of the incandescent lamp can also radiate to the side, it must be ensured that such a lamp or structural unit can only be connected to the carrier in the predetermined manner.
  • the inventive design of adapter and carrier with mating surfaces ensures in a particularly simple manner that the signal or vehicle light or the structural unit can only be connected to the carrier in a predetermined orientation.
  • a sealing ring is preferably arranged between the incandescent lamp and its socket or the fitting.
  • a connection is provided in a preferred embodiment that is only to be produced or to be released from the rear of the carrier.
  • the adapter expediently contains a recess or a hole, to which a further hole is assigned on the carrier, so that a firm connection between the carrier and adapter or lamp can be produced from the back of the carrier, preferably by means of a screw. Since the carrier is in turn fastened or screwed to a vehicle body, for example, the lamp can only be removed from the carrier with an additional operation. Functional securing of the lamp is thus created without any special effort in order to prevent theft or falling out of the lamp.
  • At least one mating surface is designed as a resilient elevation, which has a nose.
  • the associated mating surface on the carrier or fitting contains a recess with a corresponding undercut, so that a snap connection is made in a simple manner when the lamp is attached to the carrier.
  • the incandescent lamp is preferably connected to the adapter in such a way that its base or side contact sleeve forms an adapter surface which is assigned a recess on the carrier.
  • the contacts of the carrier are expediently arranged in the region of the above-mentioned depression, so that the production and maintenance of the electrical connection between the carrier and the incandescent lamp is ensured in a particularly simple manner.
  • the fitting surfaces of the fitting are preferably designed as elevations and / or depressions which, depending on the incandescent lamp or the design of the --- structural unit, have predetermined distances from one another.
  • the carrier is also provided with appropriately designed depressions and / or elevations which have the above-mentioned distances accordingly.
  • Such elevations or depressions can be produced without any special manufacturing outlay, the selection of the distances providing a sufficient number of selection criteria for the key system.
  • the mating surfaces mentioned can have predetermined dimensions, i.e. for example, they can be specified accordingly in shape, in cross section or in height, so that the number of selection criteria can be increased even further without any particular effort.
  • the fitting surfaces arranged on the side of the fitting piece are designed as guide channels and / or guideways to which correspondingly designed fitting surfaces of the carrier are assigned.
  • Such guide troughs or guideways can also be produced without any special manufacturing outlay, and again there are many possible variations in terms of number, spacing and dimensions.
  • the adapter and carrier are advantageously made of plastic, with corresponding parts for the adapter surfaces already being provided in the workpieces or molds required for the production.
  • the fitting or carrier are therefore produced together with the fitting surfaces in a single operation, which is particularly advantageous in terms of costs.
  • the carrier has on its side facing the lamp an edge, the inner surfaces of which are designed as mating surfaces. Corresponding exterior surfaces are assigned to the interior surfaces mentioned on the back of the lamp.
  • the fitting surfaces mentioned are expediently essentially rectangular.
  • the carrier can be connected to a housing via further mating surfaces.
  • the carrier thus has on the one hand the fitting surfaces assigned to the lamp and on the other hand the fitting surfaces assigned to the housing mentioned. This ensures that the carrier together with the associated lamp can only be connected to a very specific housing.
  • the mating surfaces between the carrier and the housing can in principle be designed or arranged in the same way as the mating surfaces between the carrier and the lamp. In a preferred embodiment, the mating surfaces are arranged on the one hand on the edge of the carrier and on the other hand on a frame of the housing.
  • a cam is provided on the edge of the carrier and an associated groove is provided on the frame of the housing. Furthermore, the carrier and the housing have holes which are assigned to one another. The production of a connection between the carrier and the housing is particularly simple since only the cam has to be hooked into the groove mentioned and then a screw has to be screwed into the holes mentioned.
  • the lamp shown in Fig. 1 contains an incandescent lamp 2, a concave mirror reflector 4, a transparent cover cap 6, which is provided in its area 8 with retroreflective prisms, and a fitting 10.
  • the fitting 10 is essentially designed as a flat plate and is on the seam 11 welded or glued together with the transparent cover plate 6. The lamp thus forms a single complete unit from which the incandescent lamp 2 can no longer be removed.
  • the light bulb 2 is rather firmly connected to the adapter 10 or to the complete unit.
  • the fitting 10 contains on its back 13 fitting surfaces which are designed as cylindrical ridges 12. Further mating surfaces are arranged in the form of blind holes 14 on the adapter 10. On the front 15 of the fitting 10 there is a socket 17 for receiving the light bulb 2.
  • the light bulb 2 protrudes with its bottom contact 16 and the side contact sleeve 18 from the back 13 of the fitting 10.
  • the side con Clock sleeve 18 thus, like the elevations 12, represents a mating surface.
  • the incandescent lamp 2 is connected directly to the fitting 10, a sealing ring 19 being provided for sealing between the side contact sleeve 18 and the inner wall of the socket 17.
  • the sealing ring 19 prevents moisture from penetrating into the interior of the lamp or structural unit. Since the seam 11 between the fitting 10 and the cover cap 6 is also water- and moisture-tight, no moisture can therefore preferably form or precipitate in the interior or on the reflector. Thus, the concave mirror reflector 4 is protected from damage in a simple manner.
  • FIG. 2 shows a top view of the lamp in viewing direction A according to FIG. 1. The arrangement and design of the abovementioned fitting surfaces can be seen immediately.
  • the elevations 12, which are hollow on the inside, are located in the region of the corners, the elevations 12 mentioned each having the same outside diameter.
  • the blind holes 14 and the incandescent lamp 2 with the side contact sleeve 18, however, are arranged in the middle. It can be seen that with such a fitting, the number of fitting surfaces, their spacing from one another and their dimensions can be varied in many ways.
  • the carrier 30 matching the lamp described is shown in longitudinal section in FIG. 3 and in a top view in FIG. 4.
  • the carrier 30 contains two holes 34 in the middle, through which holes the rear 3 9 screws 35 are inserted.
  • the screws 35 are expediently self-tapping metal thread screws. If the lamp is plugged onto the carrier 30 from the front, the screws 35 can be screwed into the blind holes 14 of the adapter 10. The lamp can therefore no longer be easily removed from the carrier, and security against theft of the lamp is created in a simple manner.
  • the carrier 30 also contains holes 32 as mating surfaces, which are located in the region of the corners of the carrier 30.
  • the holes 32 correspond to the elevations 12 of the adapter 10 in terms of number, location, spacing and dimensions. Therefore, only one lamp, as shown in FIG.
  • the carrier 30 also contains contact strips 36, 38.
  • the bottom contact 16 and the side contact 18 are connected to the contact strips 36 and 38 mentioned.
  • this is only possible if a lamp according to FIG. 1 is plugged on. In the case of luminaires with a different design, the electrical contact cannot be established.
  • F ig. 5 shows a lamp similar to that shown in FIG. 1, but there are no blind holes for receiving screws. Instead, there are relatively deep holes 50 which have an undercut 52.
  • FIG. 6 shows the carrier for the lamp according to FIG. 5.
  • This carrier contains ridges which are designed as resilient tongues 56 with lugs 54.
  • the elevations 56 are assigned to the holes 50 mentioned, so that a snap connection is made when the lamp is attached to the carrier.
  • a key system can be created by appropriate design or arrangement of the holes 50 and the elevations 56 mentioned.
  • additional elevations and corresponding depressions on the lamp and support will be provided, similar to the above-mentioned embodiments, in order to obtain a simple key system, especially since the movement of undercuts to other locations in a plastic tool is relatively complex. So you can always leave the recesses or holes 50 for the locking connection in the same place and only change the other elevations and depressions of the key system, which can be kept smooth in a simple manner.
  • the above-mentioned resilient elevations with a nose are arranged on the fitting instead of the holes, while the carrier has the associated holes with an undercut.
  • Such an embodiment is particularly advantageous with regard to theft protection or unintentional replacement of lights or structural units, since here too, similar to the screw connection described above, the latching connection can only be released from the rear of the carrier.
  • FIG. 7 shows a lamp similar to that in FIG. 1, the fitting 10 of which, however, has fitting surfaces arranged on the side 60.
  • the mating surfaces are designed as guide channels 61 or guide tracks 62.
  • guide channels or guideways can also be arranged in a suitable number, shape and size on the circumference of the adapter or the lamp in order to enable the necessary distinction. If necessary, such lateral guide troughs or guideways can also be combined with the elevations or depressions described above on the back of the adapter.
  • the incandescent lamp 2 is not directly connected to the adapter 10, but rather indirectly.
  • the concave mirror reflector 4 has on its rear side a cylindrical projection 64 which bears against the adapter 10.
  • the incandescent lamp 2 is inserted into a cylindrical bore of the extension 64 mentioned.
  • the cylindrical extension 64 of the concave mirror reflector 4 also receives a sealing ring 19 and a spacer ring 66, the latter in turn abutting the fitting 10 and causing the sealing ring 19 to be braced.
  • F ig. 9 shows an exploded view of a lamp, a carrier and a housing 68 accommodating the carrier.
  • the lamp is shown in view, so that the cover cap 6 and elevations 12 and part of the contact sleeve of an incandescent lamp can be seen.
  • the ridges 12 have different diameters and are assigned corresponding to the holes of the carrier 3 0 32nd
  • the carrier 30 contains on its front side 70 facing the lamp an edge 72, the inner surfaces 74 of which are designed as adhesive surfaces for the lamp.
  • the outer surfaces 76 on the rear 13 of the lamp are designed as mating surfaces which are assigned to the inner surfaces 74 of the edge 72.
  • the back 30 of the carrier 30 and the lamp connected to it in the manner already explained above can be connected to the housing 68.
  • the housing 68 contains an essentially rectangular frame 82, the outer surfaces 84 of which engage in an edge 86 of the carrier 30 arranged on the rear side 80.
  • the outer surfaces 84 and the inner surfaces 88 of the edge 86 in turn represent mating surfaces assigned to one another, so that only a specific support and thus only a specific light fixture can be connected to the housing 68.
  • the carrier 30 on the upper inner surface of the edge 86 has a cam 90 which engages in a corresponding groove 92 in the housing 68.
  • the carrier has at its lower end a shoulder 94 with a bore 96, which is associated with a further bore 98 on the housing 68.
  • the lower outer surface 100 of the frame 82 is chamfered.
  • FIG. 10 shows a view of the lamp in viewing direction C according to FIG. 9.
  • the inclined arrangement of the surfaces 102, 104 and 106 of the covering cap 6 can be clearly seen here.
  • two further elevations 12 have a smaller diameter, and the arrangement or design of the elevations and the associated holes on the carrier 30 described ensures that the lamp can only be connected to the carrier 30 in the manner shown . This prevents swapping from above and below.
  • FIG. 11 shows a view of the carrier 30 in viewing direction D according to FIG. 9.
  • Fastening parts 108, 110, 112 and 114 are provided, to which contact strips (not shown here) can be fastened.
  • the cam 90 can be seen, which is used for fastening to the housing 68.
  • FIG. 12 shows a view of the carrier 68 in the viewing direction E according to FIG. 9.
  • the outer surfaces 84 of the frame 82 are substantially perpendicular to the plane of the drawing.
  • the frame 82 has a groove 92 at the top in order to enable the carrier 30 to be easily attached.
