Abstract

The invention relates to a low-pressure gas discharge lamp comprising a gas discharge vessel with means for generating and maintaining a low-pressure gas discharge. It is an object of the invention to improve the luminous efficacy of a low- pressure gas discharge lamp containing a gas filling with an indium compound. According to the invention this is achieved by a low-pressure gas discharge lamp where less luminescence processes are employed. The low-pressure gas discharge lamp comprises a gas discharge vessel containing a gas filling on the basis of an indium halide InX, where X = F, Cl, Br, I, or a mixture of several indium halides. As a characteristic feature the gas filling includes additionally a sodium halide NaX, where X = F, Cl, Br, I, or a mixture of several sodium halides. The additional component consisting of one or more sodium halides emits light in the range of 590 nanometers. Use of a red phosphor in order to gain white light is superfluous then. The gas discharge emits light with a wavelength of 451 nanometers, blue and green light of one or more phosphors converting the UV radiation and light with a wavelength of 590 nanometers.
