Definitions
- the invention relates to an incandescent lamp for vehicle headlights according to the preamble of patent claim 1.
- it is a two-filament halogen incandescent lamp for motor vehicle headlights.
- Such an incandescent lamp is for example in the patent application DE 195 44 012 disclosed.
- This patent application describes a two-filament halogen incandescent lamp for a motor vehicle headlight with two incandescent filaments and a shading device, which are arranged in the Lampengetschreib.
- One of the filaments that as Secondary filament is called, usually serves to generate the low beam while the other filament, referred to as the main filament, usually used to generate the high beam.
- the secondary spiral is close to the shading device arranged so that their light from the shading device partially shaded.
- a Wendelabgang the Mauchtl is by a Penetrated fürbruch in the shading device and with a power supply wire welded. The breakthrough can be an unwanted increase lead the scattered light component.
- the incandescent lamp according to the invention has at least one filament and a shading device for the at least one filament, which is in a lamp vessel are arranged, wherein the shading device is a hook-shaped tab has, which extend at a transverse to the helical axis of the at least one filament Edge of the shading device is formed and that with a spiral outlet the at least one filament is connected.
- the shading device and the hook-shaped tab are made of a metal sheet shaped. This allows the tab already during production the shading device produced as part of the shading device become.
- the Wendelabgang connected to the tab is the at least one filament advantageously surrounded by a metal foil of molybdenum or tantalum to to ensure a good weld.
- a metal foil of molybdenum or tantalum can be better with the preferably made of molybdenum sheet metal Shading device or with the tab of the shading device weld as the filament spiral out of tungsten filament.
- the preferred embodiment of the invention is a Two-filament halogen incandescent lamps intended for use in motor vehicle headlights is.
- This lamp has two filaments 4, 5 and a shading 6, the in a substantially cylindrical lamp vessel 1 made of tempered glass or quartz glass are included.
- the first filament 4, also called a secondary filament is used to generate the low beam and is located close to the shading 6, which partly shadows the light emitted by the secondary spiral 4.
- the second filament 5, which is also referred to as a main filament, is used to generate of the high beam.
- the lamp vessel 1 has a sealed end 1a, which in the Lamp base 2 is fixed.
- the dome 1 b of the lamp vessel 1 is provided with a light-absorbing black or silver-colored coating provided.
- the circular cylindrical, translucent area of the lamp vessel 1 can optionally with a translucent Blue or bluish coating can be added to the color temperature of the light emitted by the lamp to about 4000 Kelvin.
- the Lamp base 2 has three tabs 3, each via a power supply 7, 8, 9 are electrically connected to the filaments 4, 5.
- the power supply lines 7, 8, 9 are gas-tight in the sealed end 1a of the lamp vessel 1 embedded.
- the quartz glass bar 10 serves to fix the Stromzuersdraihte 7, 8, 9 during assembly of the lamp frame 4, 5, 6, 7, 8, 9. Details of the invention Incandescent filament suspension are shown in FIG.
- the first spiral outlet 41 of the secondary spiral 4 is covered with a molybdenum foil 11, formed with the free leg 611 of the shader 6, hook-shaped Tab 61 is welded.
- the free leg 611 extends parallel to the helical axis and parallel to the first helical departure 41 of the auxiliary helix 4.
- the other leg 612 of the hook-shaped tab 61 is at a transverse to the helical axis the auxiliary spiral 4 extending edge of the Abschatters 6 is formed.
- the hook-shaped Tab 61 has approximately the shape of the letter U, is one piece formed with the shielding 6 and consists, as well as the shader 6, of molybdenum sheet.
- the width of the tab 61 is 2 mm and its thickness corresponds to Thickness of molybdenum sheet from which shader 6 is made.
- the of the Secondary spiral 4 opposite surface of the Abschatters 6 is connected to the power supply wire 8 welded.
- the second spiral outlet 42 of the secondary coil 4 is of surrounded by a molybdenum foil 11 and welded to the Stromzutrynmg 9.
- the first spiral outlet 51 of the main coil 5 is wrapped with a molybdenum foil 11 and welded to the power supply 8, while the second, also from a Molybdenum foil 11 wound coil outlet 52 welded to the power supply 7 is.
- the invention is not limited to the embodiments explained in more detail above.
- the free leg 611 of the hook-shaped tab 61 does not necessarily have run parallel to the filament outlet 41 of the filament 4, but instead instead also be arranged transversely to it.
- the tab 61 may instead of U-shaped on another way to be bent to a hook.
- the two filaments 4, 5 must not necessarily single-helical light-emitting sections 43 and uncoiled ones Have spiral outlets, but instead can also double-wound light-emitting sections and single-helical coil outlets have.
- the molybdenum foils 11 can be dispensed with.
- the molybdenum foils 11 serve only as a welding aid, since they better with the also consisting of molybdenum power supply wires 7, 8. 9 weldable are as the Wolfram existing Wendelab réelle the filaments 4, 5.
