    • A light source wherein a spiral line pulse generator, having an output coupled to one electrode of a metal halide discharge lamp and an input for coupling to a source of lamp operating power, provides high voltage, short duration lamp starting pulses. The spiral line pulse generator includes two conductors and two insulators, each in the form of an elongated sheet, in an alternating arrangement which is rolled together in a spiral configuration having a plurality of turns. The high voltage, short duration pulse is provided upon closure of a low inductance switch coupled between the conductors. A thermal switch can be utilized to bypass the spiral line pulse generator after lamp starting. The spiral line pulse generator can be enclosed within the lamp base of the light source.
    • 一种光源,其中具有耦合到金属卤化物放电灯的一个电极的输出和用于耦合到灯工作电源的输入的螺旋线脉冲发生器提供高电压,短持续时间的灯起动脉冲。 螺旋线脉冲发生器包括两个导体和两个绝缘体,每个绝缘体呈细长片的形式,呈交替布置,其以具有多个匝的螺旋结构卷绕在一起。 在连接在导体之间的低电感开关闭合时提供高电压,短持续脉冲。 灯启动后,可以使用热开关绕过螺旋线脉冲发生器。 螺旋线脉冲发生器可以封闭在光源的灯座内。
