摘要： A ballast for lighting a high intensity discharge lamp having a power factor correction scheme. The power factor correction scheme includes a triac. To prevent the triac from damage when the lamp is not lit and power line transients are present, the triac is turned ON. The triac is also turned ON whenever the lamp is lit.

摘要： An ignition scheme for starting a high intensity discharge lamp requiring energy in the form of ignition pulses to be provided to the lamp prior to and substantially throughout the glow load of the lamp. An ignitor includes a bilateral switching device such as, but not limited to, a SIDAC having a breakover voltage corresponding to the lamp voltage during the lamp glow mode. The ignition scheme substantially eliminates the lamp remaining in its glow mode for a prolonged period of time thereby minimizing the possibility of lamp destruction from damage to the lamp electrodes.
摘要翻译：一种用于启动高亮度放电灯的点火方案，其需要以点火脉冲的形式提供能量，以在灯的辉光负载之前和基本上在整个发光负载下提供给灯。点火器包括双向开关装置，例如但不限于在灯发光模式期间具有与灯电压相对应的突破电压的SIDAC。点火方案基本上消除了在其辉光模式中保持长时间的灯泡，从而最大限度地减少了灯损坏灯灯电极的可能性。

摘要： An improved power supply for one or more electric discharge lamps includes a high frequency oscillator-inverter circuit coupled to the output of a full-wave rectifier circuit via a transformer primary winding (25). The rectifier circuit is energized from a low frequency source of AC voltage. The oscillator-inverter circuit supplies high frequency oscillations to the lamp via a frequency-dependent ballast coupling circuit. A regenerative power supply is coupled to the transformer primary winding by means of a secondary winding (62) of the transformer thereby to charge a capacitor (49) operative as a switchable auxiliary supply voltage for the oscillator-inverter circuit. Improved start-up operation is achieved by winding the transformer (25, 62) so as to provide a polarity inversion for the supply of electric energy to the regenerative power supply.
