LOW-PRESSURE MERCURY VAPOR DISCHARGE LAMP

摘要

A low-pressure mercury vapor discharge lamp is provided with a discharge vessel (10) having first and second end portions (11). The discharge vessel encloses a discharge space provided with a filling of mercury and an inert gas in a gastight manner. Each end portion (11) supports an electrode (20) which is arranged in the discharge space and secured to current supply conductors (30A, 30B) which are passed through the end portion (11) so as to project outside the discharge vessel (10). According to the invention, a segment (31A) of at least one current supply conductor (30A), which extends between the end portion (11) and the electrode (20), is covered with an amalgam. Said region (35A) is situated at a distance da from the end portion (11). The amalgam can be relatively easily applied in the discharge lamp according to the invention.
