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 which is suitable in particular for use in automobile technology. The metal halides conventionally used as voltage gradient formers in mercury-free discharge lamps have various disadvantages as their proportional quantity in the gas filling increases, which disadvantages manifest themselves in particular in the form of an intensified arc constriction and arc curvature, and possibly also of a reduced diffuseness of the discharge arc. All these disadvantages are at least substantially avoided in that the use metal halides as voltage gradient formers is dispensed with, and that instead xenon is introduced into the gas filling at an increased pressure which excites an arc discharge.

Abstract: A high-pressure gas discharge lamp (HID [high intensity discharge] lamp) is described which is in particular free from mercury and suitable for use in automobile technology. The lamp is remarkable in particular for a discharge space (2) which has a volume which is reduced by a given factor in comparison with the volume of the discharge space of known mercury-containing discharge lamps. The quantity of the light-generating substances in the discharge space (2) is reduced by the same factor in the simplest case, or even more strongly. This avoids the risk of an impairment of the imaging properties of the lamp because of non-evaporated light-generating substances which may shade off a portion of the luminous discharge arc (21) and/or the tips of the electrodes (3).
