Definitions
- the invention an electric lamp according to the preamble of claim 1.
- Such an electric lamp is for example in the international patent application WO 97/40521 discloses.
- This laid-open specification describes an electrical one Incandescent lamp, in particular a motor vehicle headlight lamp, with an in a glass lamp bulb enclosed and a lamp base made of metal and plastic parts. The sealed gas-tight The end of the lamp bulb is fixed in a metal holder, which in turn is in the plastic base part provided with the electrical connections of the lamp is anchored. The led out of the lamp bulb, connected to the filament Power supplies are in the interior of the plastic base part with the welded electrical contacts of the lamp formed as contact lugs.
- the contact tabs point to the welding of the power supply and the contact tab each have a hole through which the corresponding power supply leads is.
- the power supply ends passed through are with the contact tab welded.
- the interior of the plastic base part is with a lid locked.
- the Lamp base on hose-like silicone parts through which the power supply leads are, and with a press fit in the bushings of the plastic base part for the power supplies are arranged.
- the press fit is made with the help of Contact flags are created, which exert pressure on the silicone hoses.
- the electric lamp according to the invention has a lamp base, a translucent Lamp bulb, at least one enclosed by the lamp bulb Illuminant, at least two power supply wires led out of the lamp bulb for supplying power to the at least one lamp and one Bracket for the lamp bulb and one with at least two contact tabs trained electrical connections of the lamp provided plastic base part, in which the bracket is anchored.
- at least two contact lugs each have a groove, in each of which a power supply wire through a welded connection with the corresponding contact lug is fixed.
- the at least two contact tabs are included in the invention Provide means for threading the power supply wires into the respective groove.
- the lamp base also has at least one for performing the welding of the power supply wires with the breakthrough serving for the contact tabs.
- the aforementioned features of the lamp according to the invention make it possible to Inject contact flags into the plastic base part and on additional agents to seal the lamp base against the ingress of humidity, such as for example silicone hoses or potting compound. Besides that is too no cover is required to close the interior of the base.
- the weld joint between power supply wires and contact lugs takes place in the invention Lamp, for example with the help of a laser, through a tiny one Breakthrough in the lamp base.
- the aforementioned breakthrough is advantageously in the bracket and not in the sealed plastic base part.
- Advantageously are used to produce the aforementioned welded joint the lower melting temperature, the contact tabs made of sheet steel rather than heating the lead wires made of molybdenum.
- the means for threading the power supply wires advantageously point to each groove has two webs which laterally delimit the groove, the one facing the groove Edge of at least one of these webs is provided with a slope.
- particularly preferred exemplary embodiment of the invention have those facing the groove Ensure the edges of both bridges each have a slope on these slopes automatic, problem-free threading of the power supply wire ends when installing the lamp in the grooves of the contact lugs.
- Advantageously own the two webs delimiting the groove have different lengths. This allows the longer bar serve as a guide for the power supply wire to be threaded.
- the shorter of the two webs advantageously has a smaller width than that longer jetty.
- the preferred embodiment of the invention is a Single-filament halogen lamp for use in a motor vehicle headlight is provided.
- This lamp has a glass, essentially cylindrical Lamp bulb 10 with a gas-tight squeeze foot 10a.
- the Dome 10b of lamp bulb 10 is provided with a light-absorbing coating.
- a light source that is aligned parallel to the lamp bulb axis serves as the light source Incandescent filament 11, which is electrically conductive with two led out of the squeezing foot 10a, Power supply wires 12, 13 connected from molybdenum wire is.
- the squeezing foot 10a of the lamp bulb 10 is in a metallic holder, that of the cup-like holder part 14a, the intermediate ring 14e and the annular Carrier sleeve 14b is fixed.
- the lamp base is also provided with the electrical connections 16, 17 of the lamp Plastic base part 15 in which the annular metallic support sleeve 14b is anchored.
- the carrier sleeve 14b has three reference lugs lying in one plane 14c and a pressure spring 14d for mounting the lamp in the reflector 20 a motor vehicle headlight.
- the reflector 20 is sealed by means of a silicone sealing ring 19 on the outer wall of the reflector 20 and rests on the plastic base part 15.
- Figure 1 the construction of the lamp according to the preferred embodiment and their use in a headlamp schematically shown.
- the electrical connections 16, 17 of the lamp consist of two metallic contact tabs 16, 17, each welded to one of the power supply wires 12, 13 are (not shown in Figure 1).
- the contact lugs 16, 17 are made of one Made of sheet steel and injected into the plastic base part 15 of the lamp base. They 16, 17 each consist of an L-shaped steel sheet.
- One each Leg 16a, 17a of the L-shaped contact tabs 16, 17 is designed as a plug contact, while the other leg 16b, 17b is equipped with a groove 16c, 17c, into each of the angled ends 12a, 13a of a power supply wire 12, 13 is threaded.
- the areas normally hidden in the cross section of FIG. 2 the contact lugs 16, 17 are shown in dashed lines in FIG.
- the angular range the L-shaped contact tabs 16, 17 is sealed in the plastic base part 15 injected and therefore normally not visible.
- the grooves 16c, 17c are each laterally delimited by two webs 16d, 16e and 17d, 17e of different lengths. Both webs 16d, 16e and 17d, 17e each have on their groove 16c, 17c facing edge a slope 16f, 17f, which is used to thread the power supply wire 12, 13 serve in the groove 16c, 17c.
- the shorter web 16e, 17e has a smaller width than the longer web 16d, 17d.
- the weld connection between the power supply wires 12, 13 and the contact tabs 16, 17 is by briefly heating the material of the shorter webs 16e, 17e over it Melting point produced by means of a laser.
- the carrier sleeve 14b is provided with an opening 18 at the level of the webs 16d, 16e, 17d, 17e, via which the laser welding of the power supply wires 12, 13 to the short webs 16e, 17e of the corresponding contact tab 16, 17 after assembly of the lamp base.
