    摘要: The invention relates to a low-pressure mercury vapor discharge lamp (10) comprising a metal compound which is selected from the group formed by compounds of titanium, zirconium, hafnium and their mixtures. The effect of adding the metal compound selected from said group to the gas filling of the discharge space (14) results in an increased efficiency of the low-pressure gas discharge lamp (10), because part of the emitted light from the discharge space (14) is in the visible range of the electromagnetic spectrum. In one embodiment of the invention, the low-pressure gas discharge lamp (10) produces substantially white light without the use of a luminescent layer (16) comprising a luminescent material. In another embodiment of the invention, the luminescent layer (16) is applied to the discharge vessel (12) of the low-pressure gas discharge lamp (10). The light emitted by the luminescent material can be mixed with the light emitted from the discharge space (14) to produce the required color.

    摘要: The invention relates to an improved low-pressure gas discharge lamp comprising a gas discharge vessel (1) surrounding a discharge space (2), containing a gas filling, and further comprising means to generate an electromagnetic field (3) and means for generating and maintaining a low-pressure gas discharge. The lamp is characterized in that the discharge lamp is provided with a first phosphor coating on a surface of the gas discharge vessel and with a second phosphor coating, the second phosphor coating being provided on a surface of the lamp that is more remote from the discharge space compared to the first phosphor coating, and the first phosphor coating being selected from the group of thermally stable phosphors. The low-pressure discharge lamp provides increased efficiency and reduced solarisation as compared to commercially available low-pressure discharge lamps.
