    • A discharge lamp comprising a light-transmitting discharge vessel enclosing, in a gas-tight manner, a discharge space comprising a mercury- free fill, the mercury- free fill comprising a molecular radiator compound, selected from the group of metal halides of ruthenium(III), osmium(III,IV), rhodium(III) and rhenium(III), wherein the halide is selected from the group of chloride, bromide and iodide and combinations thereof, and a buffer gas for aiding in starting and buffering the discharge, the discharge lamp further comprising discharge means for igniting and maintaining a discharge in the discharge space emits radiation in the visible range as well as possibly in the UVA range. The visible radiation spectrum is of the cold- white type, while radiation in the UV range is reduced in comparison to mercury-dosed lamps. Losses in visible light, e.g. by Stokes' shift, are thereby reduced and less energy is wasted by radiative output in the ultraviolet. Another advantage of this lamp technology is that it does not require the use of mercury vapor, which is an environmentally hazardous material with known human toxicity. It is therefore environmentally safe.
    • 放电灯,其包括透光放电容器,所述透光放电容器以气密方式封闭包含无汞填充物的放电空间,所述无汞填充物包含分子辐射体化合物,所述分子辐射体化合物选自 钌(III),锇(III,IV),铑(III)和铼(III)的金属卤化物组,其中卤化物选自氯化物,溴化物和碘化物及其组合,以及缓冲气体 为了辅助启动和缓冲放电,放电灯还包括用于点燃并维持放电空间中的放电的放电装置发射可见光范围以及可能在UVA范围内的辐射。 可见光辐射光谱属于冷白色类型,而紫外线范围内的辐射与汞灯投射灯相比有所降低。 可见光损耗,例如 由斯托克斯的转变,从而减少和更少的能量浪费辐射输出在紫外线。 这种灯技术的另一个优点是不需要使用汞蒸汽,汞蒸气是一种对人体有毒性的环境有害物质。 因此它是环保的。
