    Abstract: A mercury-free high-pressure gas discharge lamp (HID [high intensity discharge] lamp) is described which is provided for use in automotive technology. To achieve improved lamp characteristics, in particular a substantially equal luminous efficacy in comparison with lamps of the same power and a mercury-free gas filling, as well as a highest possible burning voltage, the discharge vessel (1) is provided in its wall regions (10) which are lowermost in the operational position with a coating (15) which reflects at least a portion of the infrared radiation generated during operation, such that the temperature of the coldest spots, and in particular of the light-generating substances collected there, is raised, with the result that the light-generating substances can enter the gas phase in sufficient quantities also without mercury, and in particular with the use of a metal halide as a voltage-gradient generator.

    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.
