Abstract

PURPOSE:To increase the effective amount of light emission immediately after the start of firing without increasing the light emission tube wall ratio load of the lamp, by setting the ratio between the supply voltage to the lamp and the lamp voltage under stabilization. CONSTITUTION:The sections 3, 3' having reduced inner diameter are provided at the circumferential section of the electrodes 2, 2' at both ends of a light emission tube 1. At least 250-750mm.Hg of Xenon is encapsulated in the light emission tube 1 as the starting gas. Furthermore proper amoung of mercury for providing predetermined lamp voltage and 0.05-0.5mg per 1cm<3> of the inner volume of the light emission tube of gallium halide are encapsulated in said tube 1. The supply voltage to the lamp Es and the lamp voltage under stabilization E1 are set to satisfy the followig relation 1.1<Es/E1<1.4.
