Abstract: High-pressure discharge lamp, with an outer bulb (10), on which a first terminal (12) and a second terminal (14) are provided, and with a discharge vessel (16), which is accommodated in the outer bulb (10), with a first and a second terminal (18, 20) and with an ignition apparatus (22), which is accommodated in the outer bulb (10) and is connected between the first terminal (12) of the outer bulb and the first terminal (18) of the discharge vessel (16). A switch (32), which closes depending on temperature, is connected in parallel with the ignition apparatus (22) between the first terminal (12) of the outer bulb (10) and the first terminal (18) of the discharge vessel (16). During operation of the lamp, the current therefore flows past the spiral pulse generator (32), so that no power is lost.

Abstract: An electrode (35) for metal vapor-containing discharge lamps consists of a high-melting, electrically conductive material, preferably of tungsten or a material which predominantly contains tungsten; it comprises a shaft (36) having a pin-shaped head part (37), which defines a longitudinal axis L, at least one hole (39) being arranged essentially transversely with respect to the longitudinal axis, in particular at an angle of 60 to 90° with respect to the longitudinal axis, in the region of the head part (37).

Abstract: The discharge lamp is held axially in an outer bulb. That end of the outer bulb which is remote from the cap is configured in such a way that it avoids the standard radially symmetrical convex shape. This substantially prevents reflection back onto the discharge vessel.

Abstract: The invention relates to a high-pressure discharge lamp, in particular a metal halide high-pressure discharge lamp, and a method for operating this lamp with the aid of a square-wave alternating current. According to the invention, the electrodes (2) of the lamp are dimensioned such that during operation of the lamp with its prescribed nominal power and with a substantially square-wave alternating current the product of the current density in the electrodes (2) and the cube root of the root mean square value of the alternating current has a constant value of between 5 A4/3mm−2 and 10 A4/3mm−2 during the stable operating state of the high-pressure discharge lamp after termination of the ignition phase.
