Definitions

  • the invention relates to a reflector lamp having a longitudinal axis which has a reflector and a lamp arranged in the reflector.
  • the European patent EP 0 780 884 B1 describes a reflector lamp having a longitudinal axis which has a reflector and a lamp arranged in the reflector.
  • the reflector has a reflector neck extending in the direction of the longitudinal axis and having a cavity in which the sealed end of the lamp vessel is arranged.
  • the projecting from the reflector neck power supply lines are each covered with a fastener, which rests against the outer wall of the reflector neck, and on the lamp is a resiliently formed stamped sheet metal part fixed, the spring force acts in the longitudinal axis and located on the reflector supported.
  • the spring-formed stamped sheet metal part and the aforementioned fasteners cause a play-free arrangement of the lamp in the reflector.
  • the FR 2 454 051 discloses a reflector lamp having a lamp and a reflector surrounding the lamp, the lamp having a lamp vessel with a sealed end extending along the longitudinal axis of the reflector lamp disposed in the reflector neck.
  • the lamp can be fixed without play in the longitudinal direction in the reflector without the use of additional spring elements.
  • the fastening element which is fixed to the at least one power supply and extends transversely to this current supply, and the lamp vessel which is wider in comparison to the sealed end and the cavity, which are supported on the reflector contribute to this purpose.
  • the fixing element fixed to the at least one power supply is preferably a wire arranged transversely to the power supply or an annular disk having a disk surface extending perpendicularly to the at least one power supply educated.
  • the cavity of the reflector neck, in which the pinch seal of the lamp vessel is arranged, and / or the light-reflecting part of the reflector advantageously widened conically in the direction of the light exit opening of the reflector.
  • the dimensions of the cavity in the reflector neck can also be matched to the appropriate dimensions of the pinch seal in order to achieve lateral support of the lamp in the reflector.
  • the dimensions of the at least one passage in the reflector neck are advantageously matched to the thickness of the at least one power supply.
  • a reflector lamp which is provided with a pin base of the type GU5,3 and has an electrical power consumption of about 50 W.
  • This reflector lamp has a reflector 1 made of glass and a low-voltage halogen incandescent lamp mounted therein 2 on.
  • the reflector 1 has a rotationally symmetrical, light-reflecting part 11, which essentially has the shape of a spherical cap and whose light exit opening is closed by means of a translucent disc 3 made of glass or plastic.
  • a reflector neck 12 is formed, which extends along the axis of symmetry of the spherical cap 11.
  • the symmetry axis of the spherical cap 11 also forms the longitudinal axis A of the reflector lamp.
  • the inner wall of the spherical cap 11 is formed light-reflecting.
  • the fixed in the reflector 1 low-voltage halogen bulb 2 has a glassy lamp vessel 21 with a gas-tight closed end 22, which is formed as a pinch seal 22.
  • a light source 4 in particular a consisting of tungsten filament 4 is included.
  • the ends of the filament 4 are each connected to an inner, made of molybdenum wire power supply 51, 52, which in turn are each connected via a gas-tight embedded in the pinch seal 22 molybdenum foil 61, 62 with an external power supply 71, 72.
  • the outer power supply lines 71, 72 project out of the pinch seal 22.
  • Their ends welded to the molybdenum foils 61, 62 are made of molybdenum while their ends led out of the pinch seal 22 are formed as nickel or stainless steel pins or as nickel plated stainless steel pins.
  • the halogen incandescent lamp 2 is aligned axially in the reflector 1.
  • the pinch seal 22 is arranged in a cavity 13 of the reflector neck 12, so that the two outer power supply lines 71, 72 each extend through a passage in the bottom of the reflector neck 12 to the outside.
  • the lamp vessel 21 In the spatial direction perpendicular to the longitudinal axis A and to the plane of the molybdenum foils 61, 62, the lamp vessel 21 has a greater extent than the pinch seal 22 and as the cavity 13 of the reflector neck 12.
  • the cavity 13 has in this spatial direction, at its the light exit opening 3 facing End a conically enlarged transition area.
  • the lamp vessel 21 abuts against the inner wall 14 of the reflector neck 12 in this transition region.
  • outer power supply lines 71, 72 are each welded to a wire 81, 82 made of stainless steel, which is perpendicular to the respective power supply 71 and 72 and rests against the outer wall of the reflector neck 12. Since the lamp vessel 21 is seated on the reflector 1 at the end of the reflector neck 12 facing the light exit opening 3 and the wires 81, 82 rest against the outer wall of the reflector neck 12, the halogen incandescent lamp 2 is fixed in the reflector 1 in the direction of the longitudinal axis A without play. Due to the conical transition region 14, the halogen incandescent lamp 2 is also fixed in the reflector 1 without play perpendicular to the longitudinal axis A.
  • the low-voltage halogen incandescent lamp 2 prefabricated by a conventional method is inserted into the reflector 1 likewise prefabricated by a known method via the open light exit opening, so that the pinch seal 22 is arranged in the cavity 13 of the reflector neck 12 and the external supply leads 71 , 72 project through the bushings in the bottom of the reflector neck 12 to the outside.
  • the pinch seal 22 is inserted so far into the cavity 13 until the lamp vessel 21 is seated on the inner wall 14 of the conically enlarged transition region of the cavity 13 and the reflector neck 12. In this position, the lamp 2 and the reflector 1 are fixed in a holding device (not shown).
  • the wires 81, 82 aligned transversely to the external power supply lines 71, 72 are welded to these power supply lines 71 and 72, in such a way that the wires abut against the outer wall of the reflector neck 12 or at the bottom of the reflector neck 12.
  • the wires 81, 82 are shortened to the desired length with the aid of the LASER.
  • the fixture for the lamp 2 and the reflector 1 is now removed.
  • the cover 3 is mounted for the light exit opening of the reflector 1.
  • annular disks 81 ', 82' consisting of a metal, for example of stainless steel, are used as fastening elements.
  • the reflector lamp according to the second embodiment agrees with the above-explained reflector lamp.
  • the same reference numerals as in the FIGS. 1 and 2 of the first embodiment On each of the two outer power supply lines 71, 72 an annular discs 81 ', 82' is threaded, so that the disc surfaces are arranged perpendicular to the respective outer power supply 71 and 72 and rest on the outer wall of the reflector neck 12.
