摘要： A high-pressure discharge lamp has an outer envelope (1) in which a discharge vessel (11) is arranged enclosing a discharge space (13) with an ionizable filling. The discharge vessel has two mutually opposed neck-shaped portions (2, 3) through which current supply conductors (4, 5) extend to a pair of electrodes (6, 7) in the discharge space. A lamp base (8) of electrically insulating material supports the discharge vessel. The lamp base also supports the outer envelope. The outer envelope with a volume equal to or less than 2cc encloses the current supply conductors and is connected to the lamp base in a gas-tight manner. A getter (10) is provided in the outer envelope for pumping out residual nitrogen from the outer envelope after sealing off the discharge lamp prior to operation of the discharge lamp, the getter (10) comprising at least 2.5 mbar.ml nitrogen. Preferably, the getter comprises an alloy of zirconium and aluminum or of zirconium and cobalt.

摘要： A high-pressure discharge lamp has an outer envelope (1) in which a discharge vessel (11) is arranged. The discharge vessel encloses a discharge space (13) with an ionizable filling. The discharge vessel has two mutually opposed neck-shaped portions (2, 3) through which current-supply conductors (4, 5) extend to a pair of electrodes (6, 7) in the discharge space. A lamp base (8) of electrically insulating material supports the discharge vessel (11) via the first and second current-supply conductors. The lamp base is provided with a first (14) and a second (15) contact members connected to the respective first and the second current-supply conductor, respectively. The lamp base (8) and/or the first and/or the second contact member (14, 15) function as an end-of-life device. Preferably, the lamp base is made from soft glass and the first and the second contact member are made from an oxidized nickel-iron-chromium material, preferably from a NiFeCr alloy such as vacovit.

摘要： The invention relates to a high-pressure discharge lamp with an outer envelope (1) in which a discharge vessel (11) is arranged around a longitudinal axis (22). The discharge vessel encloses, in a gastight manner, a discharge space (13) provided with an ionizable filling. The discharge vessel has a first (2) and a second (3) mutually opposed neck-shaped portion through which a first (4) and a second (5) current-supply conductor, respectively, extend to a pair of electrodes (6, 7) arranged in the discharge space (13). The outer envelope (1) has a bulb-shaped portion (2) adjacent the discharge space with a wall thickness d1. The remainder of the outer envelope has a wall thickness d2. The ratio of d1 and d2 is in the range: Formula (I). Preferably, Formula (II), the bulb-shaped portion is formed in a mold. A simplified and compact high-pressure discharge lamp is provided by the invention.

摘要： A high-pressure discharge lamp has an outer envelope (1) in which a discharge vessel (11) is arranged. The discharge vessel encloses a discharge space (13) with an ionizable filling. The discharge vessel has two mutually opposed neck-shaped portions (2,3) through which current supply conductors (4,5) extend to a pair of electrodes (6,7) in the discharge space. A lamp base (8) of electrically insulating material supports the discharge vessel. The lamp base also supports the outer envelope (1). The outer envelope encloses the current supply conductors and is connected to the lamp base in a gas-tight manner. By controlling the atmosphere in the outer envelope, a simplified and compact high-pressure discharge lamp is provided with an accurate positioning of the discharge vessel with respect to the optical axis of the lighting system. The high-pressure discharge lamp can be suitably applied in an assembly with a reflector.
