At least one of the electrodes has a longitudinal shape with a head part (50) and a shaft part (40) made from different materials and/or diameters. The shaft part is enclosed over its length by the material forming the wall. The head part consists of a first section (50a) and a second remaining section protruding into the discharge vessel. The second section is longer than the first section. Preferred Features: The first section of the head part is less than 0.7 mm. The head part has a diameter of 350-450 microns and the shaft part has a diameter of 150-400 microns. The shaft part is made from 60-85 weight % tungsten and a balance of rhenium. The head part is made from 90 weight % tungsten.

Abstract: A device and a method for the control of a gas discharge lamp are disclosed. In order to detract as little as possible from lamp life in spite of the luminous flux requirements to be fulfilled during the run-up of the lamp, the lamp is operated with an alternating current in a run-up phase which comprises at least the interval from 1 s to 3 s after lamp ignition, the amplitude of said current rising during the run-up phase. After the rise in the run-up phase, the current may first rise further or remain constant in a transitional phase which preferably follows the former phase, and is subsequently reduced until the lamp enters the stationary operational phase. The time gradient of the current is preferably chosen such here that minimum values for the luminous flux of the lamp are achieved at given moments. Particular advantages are obtained, for example, in the case of Hg-free lamps which are operated with high currents, especially during the run-up.

Abstract: A high-pressure gas discharge lamp (HID [high intensity discharge] lamp) is described which is free from mercury and suitable in particular for use in automotive technology. The lamp is particularly remarkable in that a rise in temperature of the coldest (lowermost) bottom regions ( 10 ) is achieved by an asymmetrical electrode arrangement, such that the light-generating substances accumulated in said regions enter the gas phase in a sufficient quantity upon switching-on of the lamp. The temperature of the hottest (uppermost) wall regions ( 13 ) is not raised thereby, indeed, it may even be reduced. An essential advantage of this lamp is that its external shape, its dimensions, and the electrodes ( 3 ) themselves need not be changed when the lamp is operated in a horizontal position with vertically aligned pinches ( 5 ), while the electrodes ( 3 ) are fastened each to a metal foil ( 4 ) in a suitable downwardly-shifted position.

Abstract: The invention describes a gas-discharge lamp (1) comprising a vessel (5), which vessel is partially coated with an essentially rectangular stripe (Sv) arranged circumferentially on a surface of the vessel, and wherein a first long side (14) of the stripe is situated close to a base (6) of the lamp, and the width (wv) of the stripe is such that a first angle (a?2) subtended at a lamp centre between a radius (r) and a point on the first long side (14) of the stripe comprises at most 55°, and a second angle (av1) subtended at the lamp centre between the radius and a point on a second long side (15) of the stripe comprises at most 50°. The invention also describes a reflector for a lamp, comprising a reflective interior surface realised to deflect light originating from the lamp outward to give a specific beam profile with a bright/dark cutoff line and a shoulder, and wherein the lamp, in particular a lamp as described above, is positioned horizontally in the reflector, and wherein the reflective interior surface comprises at least one beam-shaping region realised to deflect a portion of the light emitted from the lamp between 7.5° and 15° below a horizontal plane, at a specific region within the beam profile.

Abstract: Various embodiments of high-pressure gas discharge lamps are described whose electromagnetic compatibility (EMC) is substantially improved, particularly during the starting or switching-on phase of the lamp, and which are thus particularly suitable for use in an environment that is sensitive in the way it reacts to electromagnetic interference, such as in vehicles for example. This is achieved in essence by reducing the work function for electrons of the electrode material and/or by increasing the mean temperature of at least one of the electrodes and/or by increasing the homogeneity of the surface of at least one of the electrodes.
