Embodiment Construction
[0023] FIG. 1A shows very schematically a low-pressure mercury vapor discharge lamp comprising a glass discharge vessel with a tubular part, wherein the discharge vessel transmits the radiation generated in the discharge vessel 10 . The discharge vessel 10 seals in a gas-tight manner a discharge space 13 containing a filling of mercury and an inert gas mixture including, for example, argon. In a fluorescent discharge lamp, the side of the tubular portion 11 facing the discharge space 13 is coated with a luminescent layer (not shown in FIG. (Usually) A material (such as a phosphor) that emits light for visible light. Furthermore, the side of the tubular portion 11 facing the discharge space 13 is provided with one of more protective layers (not shown in FIG. 1A ).
[0024] The low-pressure mercury vapor discharge lamp is operable in a first and a second mode of operation. The first mode of operation is generally referred to as the "normal mode" of operation, while the second ...
