摘要:
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](E[Cl]3 200 (μmole/cm3)2, —[Cl] £ 10 μmole/cm3. The condition [Hg](E[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.

摘要:
A high-pressure mercury vapor lamp suitable for sterilization purposes. Germanium and oxygen are added in small quantities to the mercury and/or the mercury halides, with a molar ratio of germanium to oxygen being greater than 1. The addition of germanium monoxide increases the GAC efficiency (GAC: short for Germicidal Action Curve) of a high-pressure mercury vapor lamp, because germanium monoxide emits a strong molecular band system in the range from 250 to 280 nm.

摘要:
The invention relates to a high-pressure mercury vapor lamp suitable for sterilization purposes. The high-pressure mercury vapor lamp according to the invention is remarkable in that germanium and oxygen are added in small quantities to the mercury and/or the mercury halides. The addition of germanium monoxide furthermore surprisingly increases the GAC efficiency (GAC: short for Germicidal Action Curve) of a high-pressure mercury vapor lamp, because germanium monoxide emits a strong molecular band system in the range from 250 to 280 nm. The germicidal action of the high-pressure mercury vapor lamp according to the invention is thus increased with respect to that of conventional highpressure mercury vapor lamps. This is apparent from the fact that the GAC-weighted radiant flux is greater than before in the high-pressure mercury vapor lamp according to the invention.

A high-pressure metal halide discharge lamp which comprises, as filling, only zinc, a halogen and a noble gas. In order to improve the color rendering index, a calcium halide may be added to the lamp filling. The coupling-in of energy preferably takes place without electrodes in the radio-frequency range or in the microwave range, but may also be carried out by means of metal electrodes.
