Definitions

  • the invention specified in the main claim and in the subclaims is based on the object of providing a motor vehicle discharge lamp with an integrated means for dimming and a stable operating behavior.
  • the enveloping bulb made of tempered glass surrounding the discharge vessel and connected to the base controls the heat balance of the lamp, whereby on the one hand an improved color temperature and on the other hand an accelerated start-up of the motor vehicle discharge lamp is achieved.
  • the radiation-absorbing coating applied to the envelope bulb - the coating made of silicon iron oxide already known for motor vehicle light bulbs can be used for this purpose - only has to withstand a low thermal load.
  • the motor vehicle discharge lamp 1 shown in FIGS. 1 and 2 contains a discharge vessel 2 made of quartz glass with a pinch 3. Inside the discharge vessel 2, two electrodes 4 are arranged, which are connected to the external supply leads 6 via the sealing foils 5 and 5 ⁇ made of molybdenum.
  • the discharge vessel 2 contains 2.3 mg mercury as well as the halides of sodium, thallium and tin with a total amount of approx. 0.3 mg or possibly sodium and scandium with a total amount of approx. 0.9 mg.
  • An envelope bulb 7 made of tempered glass is placed over the discharge vessel 2 and carries at its tip an radiation-absorbing coating 8 which extends approximately to the electrodes 4.
  • this coating 8 has a clearance angle of 15 ° from the center line to the edge, which causes the asymmetrical low beam.
  • the radiation absorbing coating consists of silicon iron oxide and is applied by dipping.
  • the envelope piston 7 has at its end a pinch formed as a base 9, through which the power supply lines 6 are guided to the outside.
  • the surface of the envelope bulb 7 which is not provided with the radiation-absorbing coating 8 is provided on the inside with an IR radiation-reflecting and visible radiation-transmitting coating 10.
  • the motor vehicle discharge lamp 1 has an electrical one Power consumption from 35 W, their burning voltage is approx. 110 V.
  • FIGS. 3 and 4 represent a two-sided motor vehicle discharge lamp 11, the discharge vessel 12 of which has the melts 13 at opposite ends.
  • the electrodes 14 are connected to the power supply lines 16 via sealing foils 15, 15,.
  • the discharge vessel 12 is surrounded by a tubular envelope bulb 17 made of hard glass, the outer surface of which is provided on one side and along its entire length with a radiation-absorbing coating 18 made of silicon-iron oxide.
  • the ends of the envelope piston 17 are designed in the form of a pinch as a base part 19.
  • the uncoated part of the envelope bulb 17 is provided with a coating 20 that reflects IR radiation and transmits visible radiation.
  • the coating 18 including the clearance angle ⁇ of 15 ° is applied similarly to the previous example. The same applies to the remaining description details, which are not detailed in this figure.
  • a lamp construction is conceivable, in which a double-ended discharge vessel 12 according to FIG. 3 is used, but which is provided with an envelope bulb, which is capped on one side, similar to FIGS. 1 and 2.
  • the power supply facing away from the base is guided to the base within the envelope bulb.
