摘要:
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.

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].[Cl]≧200 (μmole/cm3)2, [Cl]≦10 μmole/cm3. The condition [Hg].[Cl]≧200 (μmole/cm3)2 achieves HgCl vapor pressures in the discharge sufficient for generating significant radiation components of the B2Σ+-X2Σ+ 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.

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 low-pressure gas discharge lamp is described that has, in a gas-discharge vessel, one or more inert gases as a buffer gas and means for producing, and maintaining a low-pressure gas discharge and that contains a gallium halide or a mixture of a plurality of gallium halides, to which indium and/or thallium may also preferably be added. A low-pressure gas discharge lamp of this kind produces sufficient UV radiation for it to be used in tanning devices.

A low-pressure gas discharge lamp is described that comprises, in a gas discharge vessel, one or more inert gases as a buffer gas, an indium halide and means for producing and maintaining a low-pressure gas discharge, in which lamp the indium halide is present as a monohalide and present in addition is a means that binds oxygen and water. The said means should bind oxygen and the oxygen in water more strongly than indium does. This object is satisfactorily achieved by indium, gallium, germanium, boron, molybdenum and/or tungsten.
