- the dimensions of the at least one bushing in the reflector neck are advantageously matched to the thickness of the at least one power supply.
- the prefabricated lamp is inserted into the prefabricated reflector in the longitudinal direction via the light exit opening of the reflector by inserting the at least one sealed end of the lamp vessel into the cavity of the reflector neck until the lamp vessel sits on the reflector,
- a fastening element extending transversely to this power supply is welded, which abuts the outer wall of the reflector neck.
- This method allows the lamp to be fastened inexpensively in the reflector since additional spring elements for supporting the lamp are dispensed with.
- the fixing of the fastener to the at least one power supply advantageously carried out by welding using a LASER. This method is therefore particularly inexpensive.
- Figure 1 is a partially sectioned, schematic side view of a reflector lamp according to the first preferred embodiment of the invention
- Figure 2 The reflector lamp shown in Figure 1 in a side view rotated by 90 degrees compared to Figure 1
- Figure 3 is a partially sectioned, schematic side view of a reflector lamp according to the second preferred embodiment of the invention
- Figure 4 The reflector lamp shown in Figure 3 in a side view rotated by 90 degrees compared to Figure 3
- the exemplary embodiment of the invention shown in FIGS. 1 and 2 is a reflector lamp which is provided with a pin base of the type GU5.3 and has an electrical power consumption of approximately 50 W.
- This reflector lamp has a reflector 1 made of glass and a low-voltage halogen incandescent lamp 2 fastened therein.
- the reflector 1 has a rotationally symmetrical, light-reflecting part 11, which essentially has the shape of a spherical cap and whose light outlet opening is closed by means of a translucent pane 3 made of glass or plastic.
- a reflector neck 12 is formed on the light-reflecting part 11 of the reflector 1 and extends along the axis of symmetry of the spherical cap 11.
- the axis of symmetry of the spherical cap 11 also forms the longitudinal axis A of the reflector lamp.
- the inner wall of the spherical cap 11 is designed to reflect light.
- the low-voltage halogen incandescent lamp 2 fastened in the reflector 1 has a glass lamp vessel 21 with a gas-tightly closed end 22, which is designed as a pinch seal 22.
- a lamp 4, in particular a filament 4 consisting of tungsten wire, is enclosed in the lamp vessel 21.
- the ends of the filament 4 are each connected to an inner power supply 51, 52 made of molybdenum wire, which in turn are each connected to an outer power supply 71, 72 via a molybdenum foil 61, 62 embedded gas-tight in the pinch seal 22.
- the outer power leads 71, 72 protrude from the pinch seal 22.
- Their ends welded to the molybdenum foils 61, 62 consist of molybdenum, while their ends led out of the pinch seal 22 are designed as nickel pins or stainless steel pins or as nickel-plated stainless steel pins.
- the halogen incandescent lamp 2 is axially aligned 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 leads 71, 72 each extend outwards through a bushing in the bottom of the reflector neck 12.
- 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 than the cavity 13 of the reflector neck 12.
- the cavity 13 faces in this spatial direction, on its side facing the light exit opening 3 End a conically enlarged transition area.

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 on the outer wall of the reflector neck 12, the halogen incandescent lamp 2 is fixed in the reflector 1 without play in the direction of the longitudinal axis A. Because of the conical transition area 14, the halogen incandescent lamp 2 is also fixed in the reflector 1 without play perpendicularly to the longitudinal axis A.
- the low-voltage halogen incandescent lamp 2 which is prefabricated by a conventional method, is inserted via the open light exit opening into the reflector 1, which is likewise prefabricated by a known method, so that the pinch seal 22 is arranged in the cavity 13 of the reflector neck 12 and the external power leads 71 , 72 protrude through the bushings in the bottom of the reflector neck 12 to the outside.
- the pinch seal 22 is inserted into the cavity 13 until the lamp vessel 21 is seated on the inner wall 14 of the flared transition region of the cavity 13 or 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 outer power leads 71, 72 are then welded to these power leads 71 and 72 by means of a LASER, in such a way that the wires rest on the outer wall of the reflector neck 12 or on the bottom of the reflector neck 12.
- the wires 81, 82 are then cut to the desired length using the LASER.
- the holding device for the lamp 2 and the reflector 1 is now removed. Finally, the cover plate 3 for the light exit opening of the reflector 1 is mounted.
- annular disks 81 ', 82' consisting of a metal, for example stainless steel, are used as fastening elements.
- the reflector lamp according to the second embodiment corresponds to the reflector lamp explained above.
- An annular disk 81 ', 82' is threaded onto each of the two outer power supply lines 71, 72, so that the disk surfaces are arranged perpendicular to the respective outer power supply line 71 and 72 and rest on the outer wall of the reflector neck 12.
- these disks 81 ', 82' are welded to the corresponding external power supply 71 or 72.
- the inner diameter of the annular disks 81 ', 82' is matched to the thickness of the power leads 71, 72. Characterized in that the lamp vessel 21 on the inner wall 14 of the conically widened transition region of the cavity 13 or the reflector neck 12 rests and the disks 81 ', 82' rest on the outer wall of the reflector neck 12, the lamp 2 is held without play in the axial direction of the reflector 1.
