Definitions

  • this shielding means is part of the holding element fixing the lamp. It consists of an electrically insulating, temperature-resistant material that is placed on the part of the holding element that is connected to the base sleeve. Dimming means and holding element can consist in one piece of a plastic part; For reasons of temperature resistance, freedom from outgassing and high-voltage insulation, however, when using high-pressure discharge lamps as the light source (s) for motor vehicle headlights, it is advantageous to produce the dimming agent from ceramic.
  • a plate is formed on the shielding means on one of its end faces, which is placed on plastic pins which are formed on the lower part of the holding element and is connected to this part of the holding element, for example by ultrasonic riveting.
  • the anti-dazzle agent itself consists of a groove, the concave side of which faces the lamp.
  • the axis of curvature of the channel generally coincides with the longitudinal axis of the lamp and the curvature itself encloses an angle ⁇ of less than 180 °.
  • the curvature encloses the angle ⁇ of 165 °.
  • the lamp shown in FIG. 1 for use in motor vehicle headlights consists of a high-pressure discharge lamp 1 which is squeezed on both sides and at the pinches of which a power supply line 2, 3 is led out of the bulb.
  • the lamp 1 is fastened by means of these current leads 2, 3 with a holding element 5 that is adjustable relative to the base sleeve 4.
  • the barrel-shaped plastic part 6 of the holding element 5 is integrally formed with pins 8 on its side facing the lamp 1, onto which a plate provided with corresponding openings is placed and riveted.
  • the plate 9 has a further opening 10 through which one of the power supply lines 2 of the lamp 1 is guided and fastened.
  • a web 11 made of insulating material is formed on the plate 9 and extends parallel to the lamp axis A-A. Because of the high operating temperature that arises at the lamp 1, the plate 9 and the web 11 are advantageously made of ceramic.
  • the web 11 carries at its free end a contact element 12 to which the second power supply 3 of the lamp 1 is attached.
  • the lamp 1 can be surrounded by a heating winding 17 for accelerating the start-up of the lamp 1, the connecting wires of which are also guided along the side of the web 11 facing away from the lamp 1.
  • the cavities formed by the holding element 5 and base sleeve 4 as well as base sleeve 4 and cover element 16 are filled with a silicone resin or provided with insulating webs which are sufficient for the current-carrying parts separate from each other.
  • the cover element 16 is snapped onto the base floor.
  • Figure 2 shows the lamp in plan view.
