Abstract: The invention relates to a high-pressure discharge lamp with a discharge vessel having a filling comprising a rare gas, for example argon, mercury, and chlorine, wherein the filling quantities of mercury [Hg] and chlorine [Cl] comply with the following conditions: [Hg].[Cl]>=200 (mumole/cm 3 ) 2 , [Cl] 3 . The condition [Hg].[Cl]>=200 (mumole/cm 3 ) 2 achieves HgCl vapor pressures in the discharge sufficient for generating significant radiation components of the B 2 Sigma + -X 2 Sigma + band system of this molecule. The condition [Cl] 3 serves to limit the chemical aggressiveness of the chlorine filling, in particular to limit the attacks on the wall and electrodes and thus to achieve longer lamp lives. The addition of chlorine-binding metals, in particular of germanium, leads to a further improvement in the radiation and life properties of the lamp.

Abstract: The high-pressure discharge lamp comprises a lamp vessel (1) in which an anode (4) and a cathode (5) are disposed spaced apart by an electrode distance D of 1-2 mm, the anode (4) having a tip (9) with a blunt end surface S. The area of the end surface S in mm2 and the lamp current I in amperes satisfy a relationship according to which 0.09

Abstract: The invention relates to a high-pressure discharge lamp with a discharge vessel having a filling comprising - a rare gas, for example argon, - mercury, and - chlorine, wherein the filling quantities of mercury [Hg] and chlorine [Cl] comply with the following conditions: - [Hg]OE[Cl] ³ 200 (µmole/cm3)2, - [Cl] £ 10 µmole/cm3. The condition [Hg]OE[Cl] ³ 200 (µmole/cm3)2 achieves HgCl vapor pressures in the discharge sufficient for generating significant radiation components of the B2S+-X2S+ band system of this molecule. The condition [Cl] £ 10 µmole/cm3 serves to limit the chemical aggressiveness of the chlorine filling, in particular to limit the attacks on the wall and electrodes and thus to achieve longer lamp lives. The addition of chlorine-binding metals, in particular of germanium, leads to a further improvement in the radiation and life properties of the lamp.

Abstract translation: 本发明涉及一种具有放电容器的高压放电灯，该放电容器具有填充物，该填充物包括稀有气体，例如氩气，汞和氯气，其中汞[Hg]和氯[Cl]的填充量符合 以下条件： - [Hg] OE [Cl]³200（μmole/ cm 3）2， - [Cl]≤10μmole/ cm 3。 在[Hg] OE [Cl]³200（μmole/ cm 3）2的条件下，放电中的HgCl蒸气压足以产生该分子的B2S + -X2S +带系的显着辐射组分。 条件[Cl]≤10μmol/ cm 3用于限制氯填充物的化学侵蚀性，特别是限制对壁和电极的攻击，从而实现更长的灯寿命。 添加氯结合金属，特别是锗，导致灯的辐射和寿命特性的进一步改进。
