    Abstract: 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.

    Abstract: A high-pressure gas discharge lamp, i.e. a HID (high intensity discharge) lamp, is described, which lamp is in particular free from mercury and suitable for use in automobile technology. The lamp is characterized in particular in that an increase in the temperature of the coldest (lowermost) bottom surface (10) is achieved by means of an eccentric arrangement of the discharge space (2) relative to the pinches (5), while the temperature of the hottest (upper) wall regions (13) is not increased, or may even be reduced. An essential advantage of this lamp is that its outer shape and the dimensions of the individual components, as well as the groove diameter of the lamp itself, need not be changed, which renders possible a very economical manufacture.
