摘要： The invention relates to a low-pressure gas-discharge lamp which, with its light in the red spectral region, influences the biological circadian rhythm by controlling melatonin secretion. The tubular glass discharge vessel, which can also be in the shape of a double helix, is filled with a noble gas or noble-gas mixture and mercury. Electrodes for the supply of energy are arranged at both ends of the discharge vessel. The discharge vessel is multicoated on the inside by phosphor layers applied one after the other. The first phosphor layer located on the glass surface consists of phosphor which is excited both by ultraviolet mercury radiation between 180 nm and 400 nm and also by the blue radiation between 400 nm and 490 nm emitted by the mercury discharge, and by the visible radiation emitted by the second or further phosphor layers between 400 nm and 550 nm, where visible light having emission maxima in the region between 500 nm and 650 nm is generated. In combination with light sources for melatonin suppression, the low-pressure gas-discharge lamp is, with its warm light, particularly suitable for stimulation of the quasi-circadian rhythm in an individual in the absence of external conditions, such as sunlight. Owing to its good colour reproduction and high energy efficiency, it meets all necessary requirements of a light source for illumination tasks and is thus also suitable for general lighting.

摘要： This invention relates to luminescent materials for ultraviolet light or visible light excitation containing lead and/or copper doped chemical compounds. The luminescent material is composed of one or more than one compounds of aluminate type, silicate type, antimonate type, germanate/or germanate-silicate type, and/or phosphate type. Accordingly, the present invention is a good possibility to substitute earth alkaline ions by lead and copper for a shifting of the emission bands to longer or shorter wave length, respectively. Luminescent compounds containing copper and/or lead with improved luminescent properties and also with improved stability against water, humidity as well as other polar solvents are provided. The present invention is to provide lead and/or copper doped luminescent compounds, which has high color temperature range about 2,000K to 8,000K or 10,000K and CRI over 90.
