发明名称 MERCURY-FREE HIGH-PRESSURE DISCHARGE LAMP WITH A REDUCED AMOUNT OF ZINC HALIDE
摘要 <p>The invention relates to a high-pressure discharge lamp for vehicle headlights, comprising a discharge vessel (10) which is sealed in a gas-tight manner and which has a discharge chamber (106). Electrodes (11, 12) and a filling for producing a gas discharge are enclosed in the discharge chamber, wherein the filling is designed as a mercury-free filling that contains at least xenon and halides of sodium, scandium, and zinc. The filling has an amount of zinc halide ranging from 0 mg to 1 mg per 1 cm3 of the discharge chamber volume; the amount of halides that is present in the discharge chamber (106) of the discharge vessel (10) ranges from 8 mg to 15 mg per 1 cm3 of the discharge chamber volume; the cold fill pressure of the xenon ranges from 1.0 megapascal to 1.8 megapascal; and the volume of the discharge chamber (106) of the discharge vessel (10) has a value ranging from 0.015 cm3 to 0.022 cm3.</p>
