Definitions
- the invention relates to an electric incandescent lamp according to the preamble of the claim 1.
- Such an incandescent lamp is disclosed in the published patent application DE 101 45 427 A1.
- This document describes a halogen incandescent lamp for a vehicle headlight, the two enclosed in a lamp vessel incandescent filaments for generating having the low beam or high beam.
- the for the production of the high beam Serving main coil is aligned transversely to the lamp axis and their Wound outlets enveloped by a molybdenum foil are each connected to a power supply wire welded.
- the auxiliary spiral serving to produce the low beam is axially aligned in the lamp vessel and has a transverse to her Winding axis extending, wrapped with a molybdenum foil Wendelabgang, the welded to the end of a power supply wire.
- the other spiral outlet This filament is made with a made of a molybdenum shield welded.
- a disadvantage of the above-described helical suspension secondary helix is that that inaccuracies when winding the filament to mechanical stresses in the filament and even lead to the twist of the filament. For example in the winding process of the auxiliary coil a quarter turn too much or too little generated, so at least one of the spiral outlets of the secondary spiral shows in the wrong direction and then can not without deformation of the filament or the Wendelabganges be welded to the power supply.
- a fastening of the filament to the power supply lines without causing mechanical stresses in the filament be enabled.
- the electric incandescent lamp according to the invention has at least one inside a Lamp vessel arranged filament and power supply for this filament, wherein at least one of the power supply lines has an angled end, with a transverse to the winding axis of the at least one filament Wendelabgang the at least one filament is connected and wherein this Angled end and the aforementioned spiral outlet in a plane transverse to the winding axis the at least one filament are arranged.
- the filament shown in Figure 1 has the filament shown in Figure 1 the A fraction of a turn too little on, so wanders the junction between the spiral outlet and the angled end of the power supply in the direction the end face of the angled end, if the other spiral outlet of the filament is considered spatially fixed. Accordingly, the junction wanders between the helical outlet and the angled end of the power supply on the angled end in the opposite direction when the Filament has a fraction of a turn too much.
- the inventive Helical suspension therefore allows a reliable in the above cases Fixing the filament to its power supply, without mechanical stresses in the filament to cause.
- the length of the angled end of the power supply is preferably one Value in the range of approx. 1 mm to 5 mm. This allows everyone in the winding process the filament usually occurring manufacturing tolerances considered become.
- the power supply equipped with the aforementioned angled end is off manufacturing reasons, preferably formed as a wire.
- the angled End of the power supply can be formed flattened to a good Welded connection with the spiral outlet of at least one filament to enable.
- the aforementioned Wendelabgang can also from a molybdenum foil Wrapped to be a good weld between the filament and the preferably to ensure existing power supply molybdenum.
- FIG 6 is an electric incandescent lamp according to the first embodiment of the invention shown schematically.
- This bulb is a so-called single-filament halogen incandescent lamp, which is equipped with a filament and is provided for a motor vehicle headlight.
- This halogen bulb has a glass lamp vessel 60, which is sealed by means of a squeezing foot 61 is. The squeezing foot 61 is fixed in a base 62.
- a filament made of tungsten wire 63 arranged and aligned parallel to the lamp vessel axis.
- the filament 63 has two helical outlets 631, 632 running perpendicular to its winding axis each with a molybdenum existing power supply wire 64, 65 are welded.
- the power supply wires 64, 65 are over the pinch 61st led out of the lamp vessel 60 and each with an electrical connection 66 and 67 of the halogen incandescent lamp electrically connected.
- FIG. 1 shows details of the helical suspension of the incandescent filament 63 in FIG. 6 pictured halogen bulb.
- the first filament exit 631 of the filament 63 is wrapped with a molybdenum foil 633 and welded to the power supply wire 64.
- the second spiral outlet 632 of the filament 63 is also provided with a Molybdenum foil 634 wrapped and with the angled end 651 of the power supply wire 65 welded.
- the angled end 651 of the power supply wire 65 and the second filament exit 632 of the filament 63 are in a common Plane disposed perpendicular to the winding axis of the filament 63.
- FIGs 2 to 4 show different views of an inventive Spiral suspension for a so-called two-filament halogen bulb, with two Incandescent is equipped and provided for a motor vehicle headlight is.
- a halogen incandescent lamp is shown schematically.
- These Halogen incandescent lamp has a substantially cylindrical, glassy lamp vessel 1, which is gas-tightly closed by means of a presser foot 1a. The top of the lamp vessel 1 is provided with an opaque coating 1b. Of the Pinch 1a is fixed in the base 2, with three electrical connections. 3 Is provided.
- the lamp vessel 1 Within the lamp vessel 1 are an axial with respect to the lamp vessel axis oriented first filament 4, the so-called auxiliary filament 4, and a second filament 5 aligned transversely to the lamp vessel axis so-called main coil 5, arranged.
- the auxiliary coil 4 is partially of a Shading device 6, which is hereinafter called dimming cap 6, surrounded. It is used to produce the low beam or the daytime running light in one Motor vehicle, while the main coil 5 is used to generate the high beam.
- the Spiral suspension for the two filament 4, 5 consists of the Abblendkappe. 6 and three power supply wires 7, 8 and 9 and the quartz glass beam 10, in the power supply wires 7, 8 and 9 are melted.
- These power supply wires 7 to 9 are passed through the pinch 1a and each with an electrical connection 3 of the halogen incandescent lamp electrically connected.
- the three power supply wires 7 to 9 are through the quartz glass bar 10 in a common plane perpendicular to the winding axis of the main coil 5 fixed.
- FIG. 5 Details of the coil suspension of the illustrated in Figure 5 halogen bulb according to of the second embodiment of the invention are in the figures 2 to 4 shown.
- the first, with a molybdenum foil 510 wrapped Wendelabgang 51 of Main coil 5 is provided with an angled end of the first power supply wire 7 welded.
- the other coil end 52 sheathed with a molybdenum foil 520 the main coil 5 is welded to the second power supply wire 8, on which also the anti-dazzle device 6 is fixed by a welded connection.
- the first, with a molybdenum foil 410 wrapped coil outlet 41 of the auxiliary coil 4 runs transverse, substantially perpendicular to the winding axis of the auxiliary spiral 4 and is with the approximately right angle angled end 91 of the third power supply wire 9 welded.
- the angled end 91 of the third power supply wire 9 and the first spiral outlet 41 of the auxiliary coil 4 are in a common Plane arranged perpendicular to the winding axis of the auxiliary coil 4.
- the angled End 91 has a length of about 3 mm.
- the second, with a molybdenum foil 420 wrapped Wendelabgang 42 is formed with a formed on the Abblendkappe 6 tab 601 welded.
