Definitions

  • the invention relates to a halogen lamp according to the preamble of claim 1.
  • Halogen lights are preferred because of their compact design as recessed lights and also have the advantage that the halogen lamps generally have a longer life than conventional incandescent lamps. Nevertheless, halogen lamps, as is customary in the case of luminaires, provide a possibility of replacing the lamp.
  • the commercially available halogen lamps are provided with two connecting pins, which are detachably inserted into corresponding sockets in a socket.
  • the socket is usually arranged behind an opening of the reflector in the lamp housing that receives the lamp base.
  • the invention is therefore based on the object to provide a halogen lamp of the type mentioned, which is characterized by a longer service life and greater ease of maintenance.
  • the socket In the luminaire according to the invention there is the possibility of exchanging the socket from the light exit opening of the housing without having to disconnect the electrical leads from the connection terminals, which are usually difficult to access.
  • the socket In the case of halogen lamps, the socket was identified as the component that is subject to faster aging than the other components of the housing. In the luminaire according to the invention, the socket can be easily replaced in a few simple steps and thus the life of the luminaire can be extended many times over.
  • the exchange can be made the socket in the installation position so that only minimal maintenance is required.
  • the socket can be plugged onto a holder having the connecting terminals and locked by turning it.
  • the socket is rotated into the locking position, surface contacts of the socket come into contact with corresponding mating contacts on the holder, so that the electrical connection takes place automatically when the socket is inserted.
  • DE-GM 88 00 561 describes a socket for halogen lamps which is specially designed for luminaire structures in which electrically conductive parts of the luminaire body are used for power conduction.
  • the electrical connection between the socket contacts and the conductive parts of the lamp body is made directly by the conductive fastening screws of the socket.
  • the connection terminals on the holder are designed as metal parts to which a socket of the type described above can be screwed.
  • a halogen recessed luminaire 10 has, according to FIGS. 1, 2 and 4, a pot-shaped recessed housing 12 which can be fixed in a recessed opening, not shown, for example a ceiling, by means of resilient tabs 14 projecting tangentially from its peripheral wall.
  • the housing 12 is divided in the drawing plane in FIG. 1 into two half-shells 12a, 12b which can be screwed together with the aid of screws running through screw channels 16.
  • An adjusting ring 18 is rotatably held in the housing 12, which overlaps and blinds the edge 22 of the opening of the housing 12 with a flange region 20 and projects into the interior of the housing with a tubular part 24.
  • a blind ring 26 is inserted into the opening at the lower end of the adjusting ring 18, which is supported on a collar 28 of the adjusting ring and surrounds the edge of a reflector 30 shown in broken lines in FIG.
  • two pockets 32 are formed, into which springs 34 can be inserted for the clamp fastening of the reflector 30. In this way, the adjusting ring 18, the blind ring 26 and the reflector 30 are connected to one another.
  • a holder 36 is arranged above the adjusting ring 18, on which a holder 38 for a holder 40 is latched with locking claws 42.
  • a halogen lamp 44 can be inserted into the socket 40 in such a way that it protrudes along the axis of the reflector 30 through a circular opening 46 into the interior of the reflector.
  • the frame carrier 36 is provided on its circumferential edge with three control surfaces 48 which rise obliquely in the circumferential direction, each of which is supported on a cam 50 projecting from the upper edge of the adjusting ring 18.
  • a helical spring 54 is arranged between the upper side of the frame carrier 36 and the upper wall 52 of the housing 12, which prestresses the frame carrier 36 against the cams 50.
  • the frame carrier 36 is held in the housing 12 in a substantially rotationally fixed manner or by means of anchors for the spring 54, not shown.
  • the cams 50 therefore slide on the oblique control surfaces 48 of the mount carrier 36 along so that the axial position of the lamp 44 changes relative to the reflector 30. In this way, the light cone of the lamp can be varied as required.
  • locking recesses 56 are formed for the cams 50 so that the collar 18 can be locked in certain angular positions.
  • the wall of the tubular part 24 of the adjusting ring 18 is provided with three pairs of longitudinal ribs 58, between each of which a spring 60 is held, which is bent in a U-shape and is pushed onto the wall of the tubular part 24 from above.
  • the springs 60 are each fixed with a bent-out tongue 62 in a corresponding latching notch on the inner surface of the tubular part 24 and have a circumferentially projecting wing 64 at the lower end of their outer leg, the lower edge of which rests on an undercut 66 of the housing 12 supports.
  • the adjusting ring 18 is held in the housing 12 against the force of the spring 54.
  • FIG. 2 shows the adjusting ring 18 in an angular position which corresponds to one end of its adjusting range and from which it can be rotated clockwise in FIG. 2 in order to vary the position of the halogen lamp relative to the reflector.
  • the curved end of one of the wings 64 bears against a ramp surface 68 on the inner wall of the housing 12, so that a greater resistance is opposed to a counterclockwise rotation of the adjusting ring.
  • the adjusting ring can be rotated into a position in which the curved ends of the wings 64 each lie in a vertical groove 70 which runs from the undercut 66 to the open end of the housing 12. In this position, the adjusting ring 18 can therefore be pulled down together with the reflector 30 out of the housing 12, so that the socket 40 is accessible through the lower housing opening.
  • the socket 40 is a commercially available socket for a two-pin halogen lamp, in which the plug-in sockets for the pins of the halogen lamp are conductively connected with metal screws 72 for the mechanical fastening of the socket.
  • the socket is thus electrically contacted via the screws 72.
  • each of the screws 72 is screwed axially into a cylindrical metal part 74 which is fastened to the holder 38.
  • the associated connecting wire 76 enters a transverse bore in the metal part 74 and is opposite to that of the screw 72 End screw 78 screwed into the metal part.
  • the connecting wire 76 is permanently fixed using the clamping screw 78. If the socket 40 has to be replaced later, the collar 18 with the reflector is removed in the manner described above and the screws 72 are loosened so that the socket 40 can be removed while the metal parts 74 remain on the holder 38.
  • Figure 3 shows a section through the holder 38 and the socket 40 in the plane perpendicular to the drawing plane in Figure 1.
  • the screws 72 pass through holes 88 in the socket 40 and are not shown, arranged in the holes 88 metal contacts with the sockets for the Pins of the halogen lamp 44 connected.
  • the metal parts 74 which at the same time form the connecting terminals for the connecting wires 76, each have a groove 90 at the lower end, which is delimited at the bottom by a flanged brim 92.
  • the metal parts 74 are inserted from above into the openings 94 of the holder 38 provided for this purpose, reinforced by collars and stepped, and firmly fixed to the holder 38 by flanging the brim 92.
  • the holder 38 is provided between the two metal parts 74 with a partition 96 which prevents a short circuit between the ends of the connecting wires 76.
  • two locking webs 80 are arranged for the pivotable attachment of a transformer 82.
  • the housing of the transformer 82 has at least one projecting arm 84 which carries a shaft 86 which can be locked in the locking webs 80.
  • the transformer 82 can thus be pivoted about the central axis of the shaft 86.
  • the dimensions of the transformer housing are chosen so that the transformer housing does not protrude beyond the cross section of the housing 12 when the transformer 82 is pivoted 90 ° counterclockwise into the vertical from the position shown in FIG.
  • the transformer can thus be inserted into a relatively narrow installation opening and can then be pivoted back into the position shown in FIG. 1, so that it can also be accommodated, for example, in a ceiling cavity with a relatively small clear height.
  • This type of mounting of the transformer generally makes installation considerably easier with halogen downlights.
  • the upper wall 52 of the housing 12 is provided with a relatively wide opening 98.
  • the clamping screws 78 are easily accessible through this opening.
  • FIGS. 4 to 6 show a modified exemplary embodiment of a holder 100, which corresponds to the holder 38 in FIG. 3, and a socket 102 for the halogen lamp 44 which has been specially adapted to this holder.
  • the socket 102 has a circular plan with two flats 104 , which serve as contact surfaces for a key for inserting and loosening the socket.
  • the holder 100 made of plastic has a recess 108 which is surrounded by a centering ring 106 and which, according to FIG. 5, receives the upper part of the holder 102.
  • Keyhole-like openings 110 are formed in the bottom of the recess 108 and can be seen in FIG. 6 in a top view. In FIG.
  • two curved slots 112, 114 extend from each opening 110 in the counterclockwise direction and delimit a resilient plastic web 116.
  • Two screws are screwed into the socket 102 from above, the hexagon heads 118 of which are spaced apart from the upper surface of the socket 102 according to FIG. 5. The distance corresponds to the thickness of the bottom of the recess 108 of the holder 100.
  • the screw heads 108 are inserted through the openings 110, and by rotating the socket by approximately 45 °, the shafts of the screws are elastically deformed into the webs 116 Slots 112 introduced.
  • the webs each have a flat recess 120, into which the shaft of the screw engages.
  • the holder 102 is positively fixed to the holder 100 in a precisely defined angular position.
  • the edge regions of the slots 112 overlapped by the hexagon heads 118 are chamfered in a ramp shape, so that the upper surface of the socket 102 is firmly tightened against the bottom of the recess 108 when the lock is made.
  • a terminal block 122 is formed on the upper side of the holder 100 and receives two spring-loaded contact pistons 124.
  • Each of the contact pistons 124 is in conductive connection with a connecting terminal 126 mounted on the upper side of the terminal block.
  • the contact pistons 124 enter the recess 108 with their lower ends and are elastically biased against connection electrodes 128, which are arranged on the top of the socket 102 and conductively with the sockets for the connection pins the halogen lamp 44 are connected.
  • the connection electrodes are arranged so that they lie exactly under the contact pistons 124 when the socket is in the locking position shown in FIG. In this way, a secure electrical contact between the terminals 126 and the socket is made when inserting the socket. If the holder 100 and the holder 102 are used in the recessed luminaire 10 shown in FIG. 1, the holder 102 can be conveniently rotated and removed from the lower opening of the housing 12 using the key into the unlocked position after removing the reflector 30.
  • the replacement of the holder is thus even easier than in the previously described exemplary embodiment, in which the two screws 72 have to be loosened and tightened again after the new holder has been inserted.
