    Abstract: Described herein is a mercury sample that has an isotopic composition that differs from the naturally occurring distribution of isotopes. In various configurations of an isotopically tailored mercury sample, the fraction of one or more isotopes is increased or decreased with respect to the natural fraction(s). A example of a lighting device comprises an envelope, a buffer gas enclosed within the envelope, a isotopically tailored sample of mercury vapor, and a current injection mechanism configured to excite the mercury vapor to emit light. In various configurations, the lighting device emits radiation at a wavelength of 254 nm and/or at a wavelength of 185 nm. In various configurations, the lighting device envelope includes a fluorescent coating that is excited by ultraviolet (UV) light emitted by the mercury vapor. In various configurations, the lighting device provides improved efficiency as compared to lamps employing mercury with a naturally occurring isotope distribution.

    Abstract: A lamp is operated with main and auxiliary amalgams. In accordance with one or more embodiments, a lamp includes an auxiliary amalgam-based material that releases mercury at an elevated temperature that is above an operating temperature of the lamp, and that absorbs mercury at temperatures below the elevated temperature. During a start-up period, the auxiliary amalgam-based material is heated to cause the material to release mercury for generating light in the lamp. After the start-up period, the auxiliary amalgam-based material is allowed to cool below the elevated temperature and absorb mercury, while the lamp continues to operate for generating light using a main amalgam.

    Abstract: A light tube comprises an inner light source (20), an outer transparent body (30), a vacuum seal (40), a filter driver (50) and a power connector (60). The outer transparent body (30) comprises an inner layer and an outer layer of vacuum glass, and the diameter thereof is at least 7mm and the length thereof is at least 60mm. An interlayer exists between the two layers of glass, and the air pressure inside the interlayer is less than 11-1Pa. Inner surfaces of the interlayer is coated with a low-radiation film. The filter driver (50) comprises two parts which are a driver and an EMC filter.

    Abstract: In a known method for operating an amalgam lamp with a rated power P
    optimum , provision is made for a lamp voltage U
    optimum suitable for maximum UVC emission to be applied or for a lamp current I
    optimum suitable for maximum UVC emission to flow between electrodes, wherein the discharge space is accessible to an amalgam deposit which can be heated by means of a heating element by conducting a heating current I
    Heiz through the heating element. In order to specify, on this basis, an operating mode which ensures stable operation in the range of the power optimum, the invention proposes setting a setpoint value for the lamp current I
    soll which is lower than I
    optimum , and switching on or increasing the heating current I
    Heiz when the lamp current drops below a lower limit value I1 while switching off or reducing said heating current when the lamp current exceeds an upper limit value I2.
