    摘要: To prevent lamp extinction during dead time of an inverter circuit of a full bridge system, to reduce delays of the rising time and the falling time of rectangular waves which have been output by the inverter circuit and to prevent formation of a phenomenon of momentary darkening of the radiant light, the discharge lamp is operated with an alternating current with rectangular waves which is produced by an inverter circuit of a full bridge system. When the inverter circuit of the full bridge system is driven a dead time is taken in which all switching devices are turned off. In the rear stage of the inverter circuit of the full bridge system, there is an inductance. The value of the inductance is fixed such that LL≧VL/IL·Td (VL being the luminous voltage of the discharge lamp, IL being the current and Td the dead time). Current can flow in the discharge lamp during the dead time by the energy stored in this inductance.

    摘要: The invention relates to a high pressure mercury lamp which is operated with an internal pressure at least equal to one hundred and some dozen atm and in which the thermal load and gas convection are considered. A fused silica glass discharge vessel is filled with mercury in an amount at least equal to 0.15 mg/mm3 and rare gas. The length of the electrode which projects into the discharge vessel and which is positioned at the top is greater than the length of the electrode which projects into the discharge vessel and which is positioned at the bottom. Where the lamp wattage is W (W) and the maximum value of the inside diameter in the direction perpendicular to the axis which extends between the pair of electrodes within the discharge vessel is D (mm), the following conditions are met: 0.35×(W)½≦L1≦0.69×(W)½ L2≦0.76×(W){fraction (1/2.64)} and at the same time (2.50)e0.0022W≦D≦(5.0)e0.0034W.
