Abstract

The invention relates to a mercury-free high-pressure gas discharge lamp with a defined inner bulb volume of its burner space, suitable for increasing the discharge arc diffuseness and suitable for reducing the discharge arc curvature, in particular in the case of high xenon gas pressures, and to the use thereof for lighting purposes, in particular for motor vehicles, wherein the total inner bulb volume of the burner space is constituted by: a volume A, which is the region occupying the space between the first and the second electrode tip extending into the burner space, a volume B, which is the region occupying the space in a direction away from the electrode tip of the first electrode along this electrode to the burner space wall of the inner bulb accommodating this electrode, and a volume C, which is the region occupying the space in a direction away from the electrode tip of the second electrode along this electrode to the burner space wall of the inner bulb accommodating this electrode, for which it holds that volume A / volume B ≥ 10 and volume A / volume C ≥ 10.
