Definitions

  • the invention relates to an electric lamp which consists of a lamp bulb with current leads led out of the bulb, a holding element fixing the lamp bulb and a base sleeve made of plastic, the retaining element and base sleeve being connected to one another by means of high-frequency heating.
  • the lamp also has at least two base contacts which are connected in an electrically conductive manner at least to the current leads led out of the lamp bulb.
  • Such a lamp in particular for use in motor vehicle headlights, has already been proposed (P 35 28 399.8).
  • This consists of a halogen incandescent lamp, which is held in place by a metal holding element. After the lamp has been adjusted, this is connected to the plastic base sleeve by means of high-frequency heating.
  • a holding element made of an electrically insulating, high-temperature resistant material should be used.
  • the invention is therefore based on the object of providing such a holding element which fixes the lamp bulb and which, after adjustment of the lamp, can be connected to the base sleeve made of plastic.
  • the lamps piston-fixing holding element consists of plastic at least in the connection area with the base sleeve and a means made of ferromagnetic material is arranged in this connection area between the holding element and the base sleeve.
  • both the base sleeve and the holding element fixing the lamp have a circular cross section in the connection area. Since the lamp should not only be adjusted in height, but also in its inclination relative to the base sleeve, the holding element in the connection area is convexly curved in the vertical direction, so that the holding element and base sleeve interact like a ball joint.
  • the arranged between holding element and base sleeve ferromagnetic means made of, for example, a nickel-iron alloy can consist of individual sandwiched plates, but advantageously it is designed as a ring and inserted in a groove arranged on the holding element.
  • the plastic melts in the area of the ferromagnetic material by means of high-frequency heating, so that the holding element and base sleeve connect to one another.
  • the part of the holding element which holds the lamp bulb is made from ceramic, owing to the high ignition voltage of 15-20 kV and a lamp operating temperature of approximately 900.degree.
  • One way to put this ceramic part on The plastic part of the holding element is attached by ultrasonic riveting.
  • these parts can also be connected to one another by means of a snap connection, etc.
  • FIG. 1 shows a motor vehicle halogen incandescent lamp which consists of a lamp bulb 1 pinched on one side, luminous elements 2 arranged therein and current supply wires 3 connected to the luminous elements 2 and led out of the pinch.
  • the lamp bulb 1 is held at its pinch by a holding element 4 made of a high-temperature-resistant plastic, which is barrel-shaped, in particular a spherical layer.
  • the lamp consists of a cup-shaped base sleeve 5 and three base contacts 6 anchored on the side of the base base facing away from the lamp bulb 1 (only two are visible).
  • the lamp power supply lines 3 are through openings in the base base passed and welded to the base contacts 6 on the back.
  • a cover element 8 is placed on this side of the base sleeve 5. This is ultrasonically riveted to the base sleeve 5 and in this exemplary embodiment carries an adjusting ring 9.
  • the intermediate space 10 formed by the base base and cover element is additionally filled with a resin made of plastic.
  • the holding element 4 which fixes the lamp bulb is of barrel-shaped design and is thus freely movable in its height and inclination with respect to the cylindrical base sleeve 5 and thus also with respect to the adjusting ring 9.
  • the holding element 4 and the base sleeve 5, both made of physically different thermoplastics are connected to one another with the aid of an interposed ferromagnetic ring 11, which causes the plastic material in its surroundings to melt when a high frequency is applied.
  • This ring 11 can be inserted in a groove 12 arranged on the holding element 4. It is advantageously provided with openings 13 through which additional molten plastic material can swell to increase the strength of the connection.
  • the ring 11 does not completely include the holding element 4. This has manufacturing advantages.
  • the ring 11 is of a tube with a smaller diameter than that of the holder elements 4 cut off, resulting in a material saving. Then it is cut open and snapped over the holding element 4. The spring force generated by the bending of the ring 11 gives the ring 11 sufficient hold on the holding element 4 until the holding element 4 and the base sleeve 5 have been connected to one another.
  • FIG. 2 shows a high-pressure discharge lamp 14, which is squeezed on one side, with a base, and FIG.
  • the high-pressure discharge lamp 14 which is pinched on one side, is carried by a two-part holding element 15. Due to the high ignition voltage of 15-20 kV and the high operating temperature of approx. 900 ° C., the part 15a of the holding element 15 which carries the lamp is made of ceramic. This is connected to the part of the holding element made of plastic 15b, which is provided for connection to the base sleeve 16, also made of plastic, by means of ultrasonic rivets.
  • a high temperature-resistant thermoplastic as available under the trade name ULTEM 2300 or RYTO, is used for the plastic part 15b of the holding element 15.
  • the base sleeve 16 consists for example of a polyamide.
  • the base sleeve 16 does not have its own bottom part. This is covered by a cover element 17 taken over, which is snapped onto the lower end of the base sleeve 16 and through which the base contacts are passed.
  • the cavity formed by the holding element 15, base sleeve 16 and cover element 17 is filled with a resin made of plastic, as in the exemplary embodiment described above.
  • the adjusting ring 18 of this motor vehicle discharge lamp is molded onto the base sleeve 16.
  • FIG. 3 shows the lamp structure for a high-pressure discharge lamp 19 pinched on both sides, which essentially corresponds to that for the discharge lamp 14 pinched on one side.
  • the lamp 19 is also held by a ceramic part 20a of the holding element 20 and this ceramic part 20a is connected to the plastic part 20b of the holding element 20 by ultrasonic riveting.
  • the ceramic part 20a itself consists of a round plate 20a1, which rests on the plastic part 20b of the holding element 20.
  • This plate 20a1 is a trough-shaped part 20a2 formed, which is arranged parallel to the lamp 19.
  • the current lead 21 led out of the lamp bulb 19 at the end facing away from the base is electrically conductively connected to a contact 22 mounted in the groove, and this contact 22 in turn is connected to one of the base contacts 23.
  • the connection 24 between contact 22 and base contact 23 is guided along on the side facing away from the lamp bulb 19 of the channel-shaped part 20a 2.
  • the channel-shaped part has in this motor vehicle 3 additionally the function of a dimming means for generating the light distribution customary in motor vehicle lamps.
