摘要： A lighting assembly (100) includes an electronic driver circuit (110) and a discharge lamp (10). The discharge lamp (10) is driven with a steady-state average power of 20-30 W. It includes a discharge vessel (20) of a maximum inner dimension ID of less than 3 mm with two electrodes (24). A discharge vessel filling comprises a rare gas and a metal halide composition provided in an amount per volume of the discharge vessel (20) of less than 13.2 μg/μl. Electrical energy is supplied as an alternating current IL where pulses (150a-150d) are superimposed. The pulses occur in a time interval of 20% of a half-cycle time before or after a polarity change of the alternating current IL. During the pulses the current IL reaches the current value of at least 1.2 times the RMS value of the current IL.

摘要： In order to achieve a discharge lamp suited to operate under reduced nominal power of e.g. 20-30 W, a lamp is proposed with two electrodes (24) arranged at a distance in a discharge vessel (20, 120) for generating an arc discharge. The discharge vessel (20, 120) has a filling with a substantially free of mercury and comprises a metal halide and a rare gas. The lamp (10, 110) further comprises an outer bulb (18) arranged around the discharge vessel at a distance (d2). The outer bulb (18) is sealed and has a gas filling of a thermal conductivity (λ). The inner diameter (d1) of the discharge vessel is preferably in a range from 2-2.7 mm. The wall thickness (w1) is in a range from 1.4-2 mm. A heat transition coefficient (λ/d2) is calculated as thermal conductivity (λ) at 800° C. of the outer bulb filling divided by the distance (d2). The so-defined heat 10 transition coefficient is below 150 W/(m2K).

摘要： A discharge lamp (10) is disclosed with a closed discharge vessel (20) which is surrounded by a wall of transparent material. Two electrodes (30) are present, partly embedded in the wall and projecting into the interior of the discharge vessel (20). At least one, but preferably both electrodes (13) are elongate in shape and comprise a head part (50) and a shaft part (40), which are distinguished by different diameters and/or different materials. Tungsten is preferred for the head part (50) and a tungsten-rhenium alloy for the shaft part (40). The shaft part (40) is enclosed in the wall material, usually quartz, whereas of the head part (50) only a first, short portion (50a) is in contact with the wall, while its second, longer portion (50b) projects into the interior of the discharge vessel (20). Favorable diameters for the head part (50) were found to be 350 to 450 μm, and for the shaft part (40) 150 to 400 μm. A long lamp life is achieved with the electrode design according to the invention, in particular in thermally strongly loaded discharge lamps as preferred for automotive applications. There are additional advantages in a lesser crystallization of the discharge vessel (20), less burning-off of the electrodes (30), and an improved run-up behavior.

摘要： A high-intensity discharge (HID) lamp comprising an inner bulb (1) with a discharge vessel (11) and an outer bulb (2), especially for application in an automotive headlight unit is disclosed. A lamp design is proposed by which high thermal stresses and increased quartz temperatures during run-up and steady state operation of the lamp are avoided so that the light output and the lifetime of the lamp is improved. This is substantially achieved by a positioning of the inner and the outer bulb (1, 2) such that a longitudinal axis of the inner bulb (1) is displaced in the operating position of the lamp above a longitudinal axis of the outer bulb (2) so that the distance between the discharge vessel (11) and the outer bulb (2) at the top side of the lamp is decreased and the distance between both at the bottom side is correspondingly increased.
