Abstract
A low-pressure discharge lamp is described having a base housing (10), a discharge vessel (2), whose end sections are fixed to an end section of the base housing, and a contact-making system for making electrical contact with the lamp, which is located on the end section of the base housing (10) which is remote from the discharge vessel, a conductive section (5) being provided, which is electrically connected to the contact-making system and is arranged adjacent to the discharge vessel (2) in the base housing (10) in such a way that an electrical short circuit is formed around the discharge vessel (2). This makes it possible to reduce the starting voltage of the lamp. As an alternative, or in addition, to this, the cross section of the web attachments is increased, which also increases the rate of the luminous-flux run-up.
