Definitions
- the invention relates to a halogen incandescent lamp according to the preamble of claim 1.
- Such a halogen incandescent lamp is disclosed, for example, in EP 1 667 205 A2.
- This publication describes a halogen incandescent lamp with two enclosed by a lamp ⁇ vascular filaments, which are designed for different electrical services. The first, designed for ei ⁇ ne higher electrical power filament is used when using the lamp in a motor vehicle headlight for generating the high beam, while the second, designed for ei ⁇ ne lower electric power filament for generating a daytime running light is provided.
- WO 02/07188 Al discloses a halogen incandescent lamp for motor vehicle headlights with at least one designed as a single coil filament, whose dimensions and or or geometry upon a Be ⁇ operating voltage of at least 20 volts and an electric power consumption in the range from 50 watts to 100 watts are tuned, wherein the length of the single weight is in the range of 4.0 mm to 6.5 mm.
- the halogen incandescent lamp according to the invention has two, arranged in ⁇ nerrenz a lamp vessel filaments, wherein a first filament for operation with a higher electric power than the second filament is arranged, and the filaments are constructed such that their dimensions and respectively, or their geometry in each case on an operating voltage of at least 20 volts are tuned, and at least the second filament is designed as a single helix filament.
- Theschreibge- winding of the second, homowattigen filament produces a homogeneous luminance distribution with the use of the lamp according to the invention in the motor vehicle headlamp and thus allows for vehicles with a vehicle system voltage of nominally 24 volts a homogeneous daytime running lights, Po ⁇ sitionslicht or fog light.
- the single coil of the never ⁇ derwattigen filament has at least 30 turns, and a length ranging from 3.5 mm to 5.5 mm in order to achieve the best possible uniformity of the luminance distribution by the correspondingly tight arrangement of the windings.
- the helical wire diameter of the single wound of the second, low-watt filament is in the range of 40 microns to 110 microns and the outer JO easily messr is preferably in the range of 0.5 mm to 1.4 mm, the low-wattage filament to an operating voltage of at least 20 volts, in particular in the range of about 20 volts to 32 volts, and an electrical power consumption at 28 volts in the range of 15 watts to 50 watts, and especially in the range of about 17 watts to 22 watts vote.
- the first, higher-wattage filament is advantageously also designed as a single filament Glühwen- del to generate when using the lamp according to the invention in the vehicle headlight of a vehicle with a vehicle electrical system voltage of nominal 24 volts in addition to the high beam or dipped beam homogeneous luminance distribution ⁇ distribution.
- the single coil of the f ⁇ th, diwattigen filament has at least 20 turns, and a length ranging from 4.0 mm to 6.5 mm, to pass through the correspondingly tight arrangement of the windings
- the helical wire diameter of the single-turn helix of the first, higher-watt filament is in the range of 100 microns to 140 microns, and the outer diameter is preferably in the range of 1.2 mm to 2.0 mm to drive the higher-watt filament to an operating voltage of at least 20 volts, in particular in the range of about 20 volts to 32 volts, and an electrical - A -
- Power consumption at 28 volts in the range of 50 watts to 100 watts, and in particular in the range of about 55 watts to 80 watts vote.
- Figure 1 is a side view of a preferred embodiment ⁇ example of the halogen incandescent lamp according to the invention
- FIG. 1 shows a halogen incandescent lamp according to the invention for a vehicle headlight.
- These halogen incandescent lamp has a vitreous, substantially Cylind ⁇ innovative lamp vessel 10, in the interior of which two aligned parallel to the lamp vessel axis incandescent filaments 21, 22 are arranged ⁇ , which serve to generate a driving beam and a daytime running light.
- the filaments 21, 22 are formed as simple coiled tungsten wires.
- the Wen ⁇ delab sau 211, 212 and 221, 222 of the filaments 21 and 22 are each wrapped with a molybdenum foil, which serves as a welding aid when welding the Wendelab réelle 211, 212 and 221, 222 with power supply lines for the filaments 21, 22.
- a sealed end 11 of the lamp ⁇ vessel 10 is anchored in a lamp cap 30.
- the first filament 21 is partially surrounded by a shaped sheet of molybdenum ⁇ anti-dazzle device. 4
- the anti-dazzle device 4 is supported by a first power supply wire 51 which, together with a second 52 and third power supply wire 53, serves to energize the two filaments 21, 22.
- a first helical departure 211 of the first incandescent filament 21 is provided by a hump welding welded with a welding lug 41 of the shield 4 and thereby elekt ⁇ driven conductive through the dipping cap 4 ver ⁇ connected to the first power supply wire 51st
- the second filament outlet 212 of the first filament 21 is ver ⁇ welded with the third power supply wire 53.
- the first coil outlet 221 of the second filament 22 is also welded to the third power supply wire 53.
- the second coil outlet 222 of the second filament 22 is welded to the second power supply wire 52.
- the three power supply wires 51, 52, 53 each consist of molybdenum and are fixed between two with each other ⁇ fused quartz glass webs 13, so that they are arranged in a common plane.
- the three power supply wires 51, 52, 53 are passed through the sealed end 11 of the lamp vessel 10 and each electrically connected to one of the three contact lugs 61, 62 or 62.
- the three contact lugs 61, 62, 63 protrude laterally out of the lamp base 30 and form the electrical connections of the halogen incandescent lamp.
- the lamp cap 30 is formed as a metal-plastic base, which has both a metal base portion 31 and a plastic consisting ⁇ the base portion 32. In the metallic So ⁇ ckelab steel 31, the lamp vessel 10 is anchored and the existing plastic base portion 32 is provided with the electrical contacts 61, 62, 63 of the lamp.
- the first filament 21 is formed as a singly coiled incandescent ⁇ helically with a nominal operating voltage of 24 V and an electric power of 28 V in the range of about 55 W to 80 W. It is preferably used for production of the high beam.
- the data of the first filament 21 are listed in Table 1 below.
- the second filament 22 is formed to 22 W as simply coiled incandescent ⁇ helically with a nominal operating voltage of 24 V and an electric power of 28 V in the range of about 17 W. They preferably used to it ⁇ generation of daytime running light.
- the data of the second filament 22 are listed in Table 2 below.
