Definitions

  • the invention relates to a lamp reflector unit according to the Preamble of claim 1.
  • the invention is also suitable for discharge lamps, especially small-watt metal halide lamps.
  • Such lamps are usually held in the reflector neck by means of cement, see for example EP-A-495 194.
  • a lamp reflector unit is known from US Pat. No. 4,855,634, where the two led out of the pinch seal of the lamp Power supply in each case in an opening in the reflector neck through a rivet are held.
  • the rivet itself is preferably cemented into the opening.
  • a lamp reflector unit which with a halogen lamp. It has a rectangular bruise with cross ribs, by means of which the lamp in the reflector through Pot-like fastening element attached to the outside of the reflector neck is.
  • a centering disk which is attached to the pinch, secures the axial position of the lamp. Its outer edge lies on the inside of the reflector in the area of the transition between reflector contour and reflector neck on. This will change the support dimension on the lamp-reflector unit enables.
  • a lamp-reflector unit is known with two resilient disks (10) which hold the lamp in the reflector by means of elastic tongues (13) which attack the pinch seal (5).
  • the lamp-reflector unit according to the invention consists of a lamp, whose pistons are sealed at least on a first side with a seal is.
  • these are single-sided lamps pinched piston, however, the invention is also arranged axially pistons pinched on both sides. It is also for the invention not necessary to use a bruise as a seal becomes. In principle, a meltdown can also be used.
  • At least one power supply from the piston is from the seal led out.
  • the extension be designed as a pen.
  • the reflector of the assembly consists of a calotte, which is made of a reflective Contour (preferably faceted) and a reflector neck.
  • the reflector defines a reflector axis, the first or only one Sealing of the piston, generally the pinch seal, in the reflector neck is arranged.
  • the reflector neck has at least one opening near the top through which a power supply or its extension is led to the outside. in the in general, however, is any power supply arranged in the reflector neck assigned a separate apex opening.
  • Each power supply is covered by a fastener, the the outside of the apex opening.
  • a fastener a disc or a pin sleeve, i.e. a sleeve, at the outer end has a collar.
  • a fastener also a rivet, i.e. a sleeve, one at both ends Has collar.
  • the assembly contains a resilient connected to the lamp Element whose spring force acts in the reflector axis.
  • the spring element is supported in the interior of the reflector, preferably in the area of the reflector neck from, where it is under a clamping force of at least 0.3 N.
  • the clamping force is low, it is recommended that the fasteners be used the apex openings are centered.
  • The is particularly preferably The clamping force is at least 5 N.
  • the lamp is fixed like this reliable that simple perforated disks are sufficient as fasteners.
  • sleeve-like fastening elements pin sleeves, rivets
  • the diameter of which is not the diameter of the opening are exactly adjusted.
  • the resilient element is preferably a centering plate made of spring plate rests on a shoulder, preferably in the region of the reflector neck.
  • the Centering disc is connected to the pinch of the lamp.
  • the resilient element is a disc spring on the inside the opening of the reflector neck.
  • the disc spring is with the external power supply or its extension connected.
  • step a) it does not matter whether the lamp is first in the reflector is used and only then put the centering disc over the lamp or whether the centering disc is already in the reflector before insertion the lamp is used.
  • Step b) is preferably carried out at the end of step a). However, it can also already take place as an intermediate step during step a). The latter is preferred then the case when the fastener is a rivet. In this case a pin sleeve is first inserted into the apex opening from the outside and then the inner collar of the rivet made by pressing of expansion pins. When using rivets, it is recommended that the resilient element is formed by a centering disk.
  • step c) the lamp is in from above, that is, from the reflector opening Pressed towards the apex, in particular by means of a stamp.
  • connection in step d) is preferably carried out by laser welding.
  • a cover plate can also be inserted into the reflector opening be used.
  • FIG. 1 shows a halogen incandescent lamp reflector unit which consists of a Halogen lamp 1 pinched on one side with a schematically shown Luminous body 2, a bulb 3 and a pinch seal 4 is made.
  • the halogen incandescent lamp 1 sits in a reflector 5 made of aluminum-coated Glass, which consists of a faceted reflector contour 6 and a reflector neck 7 exists and has an axis x.
  • a reflector 5 made of aluminum-coated Glass, which consists of a faceted reflector contour 6 and a reflector neck 7 exists and has an axis x.
  • an annular circumferential shoulder 8 In the area of transition between contour 6 and neck 7 there is an annular circumferential shoulder 8, on which the circular edge 9 of a centering disk 10 rests.
  • the edge 9 goes inwards into an enclosure 11 for a rectangular recess about in which the pinch seal 4 of the lamp is inserted and so the lamp is supported.
  • the luminous element 2 is via two inner power supply lines 12, foils 13 and external power leads 14 connected to extension pins 15.
  • the pins 15 are through two openings 16 in the apex of the reflector led out of the reflector neck 7.
  • Two perforated disks 17 on the outside the apex openings 16 are welded to the pins 15.
  • the centering disc 10 is under a bias of 9 N, so that the Lamp is firmly locked in the reflector. With such a high bias a vote between the diameter of the pin 15 and that of the Vertex opening 16 is not necessary.
  • the reflector opening 18 is closed with a cover plate 40.
  • Fig. 2 shows the manufacture of such a unit.
  • the Lamp 1 inserted into the centering disk 10 (step a1).
  • this unit is inserted from the reflector opening 18 into the reflector 5 (Step a2) until the centering disk 10 rests on the shoulder 8.
  • the Perforated discs 17 fed (step b) and via the extension pins 15 to pushed to the apex opening 16.
  • the piston is stamped 19 3 pressed towards the apex opening 16 (step c).
  • the perforated disks 17 are welded to the pins 15 (step d). Subsequently the stamp 19 is removed.
  • Fig. 3 shows a section of a further embodiment of a Lamp-reflector unit, which corresponds essentially to the structure of FIG. 1.
  • the only difference is the use of pen sleeves 20 as a fastener.
  • the collar 21 is located on the outside of the apex opening 16 on. Its diameter is adapted to that of the apex opening 16. At a preload of 0.5 N is sufficient for this arrangement.
  • Fig. 4 shows a section of a third embodiment of a Lamp-reflector unit, which corresponds essentially to the structure of FIG. 1.
  • the only difference is in the use of rivets 25 as a fastener. Its diameter is that of the apex opening 16 customized.
  • the first, outer collar 26 of the rivet lies on the outside at the apex opening 16 on.
  • the second, inner collar 27 lies on the inside at the apex opening 16 on.
  • Rivets 25 are welded to the pins 15 in the area of the outer collar 26.
  • a fourth embodiment which is shown in Fig. 6, is on a centering disc as a resilient element is dispensed with. Instead, it will Resilient element formed by two plate springs 35, which on the pins 36th are attached by laser welding.
  • the plate springs 35 are, as in Fig. 7, connected to the lamp 1 even before installation in the reflector (Step al). Only then is the lamp 1 inserted into the reflector 5 (Step a2) that the plate springs 35 inside the apex openings 16 lie on.
  • Two pin sleeves 20 are threaded onto the pins 36 from the outside, until the collar 26 similar to that in Fig. 3 outside at the apex opening (step b). Then the lamp 1 is depressed with a stamp 19 (Step c).
  • the pin sleeves 20 are welded to the pins 36 (Step d).
  • Such an arrangement is preferably suitable for low preloads up to approx. 1 N.
  • the pin sleeves ensure a certain adjustment with the help of the apex opening
