Definitions

  • the invention is based on a halogen incandescent lamp according to the preamble of claim 1.
  • US-A-2 830 217 describes a lamp filled with noble gas, in which a power supply made of molybdenum is used, the end of which has a spade-shaped flat with a thickened end.
  • the invention is therefore based on the object of producing halogen incandescent lamps with a secure mechanical and electrical contact between the luminous element and the power supply, the assembly of the luminous element being intended to be very simple to carry out and thus easy to mechanize.
  • the diameter of the inner power supply is slightly, in particular by 5-20%, smaller than the inner diameter of the filament at the ends of the filament enables the filament ends to be threaded easily.
  • the flat near the end of the power supply the greatest width of which is slightly, in particular 5-30%, larger than the inside diameter of the coil is at the ends of the filament, ensures good electrical contact and mechanical hold of the filament throughout the life of the lamp.
  • the filament is advantageously bent away from the power supply end by 90 ° ⁇ 45 °. This results in a laterally acting tensile load on the tensioned luminous element, which in turn improves the contact in the area of the enclosed power supply end and effects an additional holding function.
  • the entire filament is doubled.
  • the inner diameter of the filament at the ends of the filament is to be understood as the inner diameter of the secondary filament.
  • This structure of the filament results in a high elasticity, which in particular supports the holding function of the flat by reducing the inner diameter of the secondary coil when the filament is subjected to tensile stress and thereby holding the filament even more effectively by the flat (self-locking).
  • the luminous body advantageously has an interruption-free interruption near its ends. By means of this interruption, the length of the one to be lit can be determined Clearly define the middle part of the filament. The ends of the filament intended for holding are delimited.
  • FIG. 1 schematically shows the front view of a 220 V halogen incandescent lamp 1 with an output of 150 W. It has a quartz bulb 2, which was filled with a halogen compound and one or more inert gases via a pump stem 3 and on which a metal base 4 was pressed using a pinch seal 5 is attached. Molybdenum foils 6 are melted into the pinch seal 5 and connect the two outer power leads (not visible), made of molybdenum, and electrically connect the two inner power leads 7, made of tungsten, in a vacuum-tight manner.
  • the two inner power supply lines 7 are components of a holding frame 8, which also comprises two coil holders 9 with meandering curvatures 10 and a hook-like part 11.
  • the components of the holding frame 8 are fixed in their position relative to one another by a crossbeam 12 made of quartz glass two filament holders 9 (made of tungsten wire) lie in one plane.
  • the double-coiled filament 13 made of tungsten is divided into several sections.
  • the two end sections 14 are held on the end parts 15 of the inner power supply lines 7.
  • the luminous element 13 is bent away from the inner power supply lines 7 (see FIG. 2).
  • four double-spiral lighting sections 17, which form an M in the projection according to FIG. They are separated from one another by secondary helix-free sections 18, on which the luminous element 13 is spread apart by the frame 8, in particular by the two meandering curvatures 10 of the filament holder 9 and by the hook-like part 11.
  • the spatial arrangement of the luminous element 13 and frame 8 is illustrated by the side view according to FIG. in which the two end parts 15 of the inner power supply lines 7 (only one end part is visible in the projection) are each angled in a plane perpendicular to the reference plane and perpendicular to the orientation of the crossbar 12 in the same direction, while the hook-like part 11 is also in one Plane perpendicular to the reference plane and parallel to the planes of the end parts 15, but in the opposite direction, is angled.
  • the fixture of the luminous body 13 on the end parts 15 of the inner power supply 7 takes place in each case by means of a flat 19 Operation of the flat 19 and its importance in the assembly of the filament on the inner power supply 7 will be explained in more detail below.
  • Figure 3 shows schematically the assembly of the filament 13.
  • the inner diameter of its secondary filament, which has an interruption 16 near the end of the filament, is 600 microns.
  • the inner power supply 7 has a diameter of 550 microns, its total length is about 18 mm.
  • the end part 15 of the inner power supply 7 thus formed is squeezed about 2 mm from the end of the power supply in such a way that the flattening 19 is formed.
  • the squeezing is preferably carried out with the aid of two cylindrical embossing dies which are pressed onto the power supply lines from two sides at the same time.
  • the flat 19 is widened in the plane formed by the inner power supply 7 and end part 15 with a greatest width of approximately 660 ⁇ m and thinned down to 440 ⁇ m perpendicular to this plane.
  • the end of the luminous element 13 and the end part 15 of the inner power supply 7 are now first aligned with one another (FIG. 3a).
  • the luminous element 13 is now plugged onto the end part 15 from one end.
  • At least two, generally about five turns of the secondary helix are pushed from the end section 14 beyond the flat 19 onto the end part 15, as a result of which the luminous element 13 on the end part 15 is supported (Fig. 3c).
  • the other end section 14 of the luminous element 13 is held on the second inner power supply 7 at the same time.
  • Both internal power supply lines 7 are already fixed to the frame 8 with the help of the crossbeam 12 (made of quartz glass) during the filament mounting.
  • the luminous body 13, which is still freely suspended between the end parts 15, is now bent upward in the region of the interruptions 16 (FIG. 3 c) and, as can be understood from FIG. 1, is guided over the curvatures 10 and hung on the hook-like part 11.
  • FIG. 4 An exemplary embodiment of a 110 V halogen incandescent lamp 1ampe with a power of 75 W is shown in FIG. 4. It has essentially the same structure as the halogen incandescent lamp of the first exemplary embodiment, but differs in accordance with the reduced operating voltage in that it is shortened by about half and now in shape of an upside-down V's executed lamp 13 Leucht. This also requires a changed structure of the frame 8 ⁇ , in that the crossbar 12 ⁇ fixes only one helix holder 9 ⁇ with a meandering curvature 10 ⁇ and two internal power supply lines 7 ⁇ (FIG. 5). The two inner power supply lines 7 ⁇ are now each bent in one plane parallel to the plane of the filament holder 9 ⁇ .
  • the luminous element 13 ⁇ can now be tensioned in the middle and flat, the plane being perpendicular to the plane of the filament holder 9 ⁇ .
  • the luminous element is mounted on the inner power supply analogously to FIGS. 3a-c, the power supply diameter now being 440 ⁇ m, the greatest width of the flat portion being 550 ⁇ m and the inner diameter of the secondary coil being 480 ⁇ m.
  • filament lamps without sections or interruptions free of secondary coils, and furthermore internal power supply lines without an angled end part can also be used.
