  • Patent number: 6977469
    Abstract: Low-pressure mercury vapor discharge lamp comprising a discharge vessel (10) having a first and a second end portion (12a, 12b), the discharge vessel (10) containing mercury and a rare gas, wherein the end portions (12a, 12b) each support an electrode (20a,20b) arranged in the discharge vessel (10) for initiating and maintaining a discharge in the discharge vessel (10), wherein an electrode shield (22a,22b) substantially encompasses at least one of the electrodes (20a,20b), and wherein said electrode shield (22a,22b) comprises an inner wall (23a) and an outer wall (24a), said walls (23a,24a) being spaced apart.

  • Patent number: 6630787
    Abstract: A low-pressure mercury-vapor discharge lamp is provided with a discharge vessel and a first and a second end portion (12a). The discharge vessel encloses a discharge space provided with a filling of mercury and an inert gas in a gastight manner. Each end portion (12a) supports an electrode (20a) arranged in the discharge space. An electrode shield (22a) encompasses the electrodes (20a) and, according to the invention, carries an electric current during operation, and is at a temperature ≧250° C., preferably ≧450° C., during nominal operation of the discharge lamp. Preferably, a first current supply conductor (30a) electrically contacts a first current divider (23a), which is electrically connected to a second current divider (23a′) via a shell-shaped body (24a).

  • Patent number: 6498432
    Abstract: A low-pressure mercury-vapor discharge lamp comprises a discharge vessel (10) and a first and a second end portion (12a). The discharge vessel (10) encloses a discharge space provided with a filling of mercury and a rare gas in a gastight manner. Each end portion (12a) supports an electrode (20a) arranged in the discharge space. Current supply conductors (30a, 30a′) extend from the electrodes (20a) through the end portions (12a) so as to project from the discharge vessel (10). An electrode shield (22a) encompasses at least one of the electrodes (20a). According to the invention, the electrode shield (22a) is mounted on the current supply conductors (30a, 30a′). Preferably, the electrode shield is clamped to the current supply conductors. The electrode shield is preferably provided with recesses to accommodate the current supply conductors. Preferably, the current supply conductors are flattened at the location where the electrode shield is mounted on the current supply conductors.
