Abstract
An electrical high-pressure discharge lamp is provided for a cosmetic skin treatment. The lamp includes an illuminating tube made of quartz glass. At least two electrodes made of metal are arranged in the illuminating tube at a spacing from each other that is larger than the internal diameter of the illuminating tube. A gas is enclosed in the illuminating tube, and the quartz glass is doped with copper and tin, which reduces the transmission by the illuminating tube for electromagnetic radiation of a wavelength shorter than 550 nm. A use of an electrical high-pressure discharge lamp of this type in a tanning device or lamp for cosmetic skin treatment is also provided.
