摘要： A fluorescent lamp ballast includes a generally flat base upon which a core and coil subassembly is mounted and covered by a ballast case. A connector bar is mounted in the forward end of the ballast case and includes a plurality of sockets having terminal pins mounted therein for selectively receiving a wiring harness. The opposing ends of the terminal pins are electrically connected to a terminal strip which is mounted to the core and coil subassembly. The terminal strips have conductors electrically connected thereto which extend to termination points on the core and coil subassembly. A second series of terminal strips is mounted to the opposite end of the core and coil subassembly, and is electrically connected to a resistor and capacitor combination. A second embodiment of the ballast augments the first embodiment with an end connector bar mounted in the rearward end of the ballast case. A second version of a terminal strip, in the second connector bar, is designed to electrically connect terminal pins to either a conductor from the appropriate coil or to "passed through" connections from terminals at the forward end. A third version of the ballast utilizes the second embodiment of the terminal strip at the forward end of the ballast case to permit rearrangement of the resistor and capacitor combination to the forward end.

摘要： In one form of the multiple voltage ballast system described herein, each of the primary coils has different wire sizes with the largest diameter wire being utilized in the 120 V primary coil. In another form of the invention, a pair of 120 V primary coils are connected in series with a 37 V primary coil so that the ballast may function as a 277 V ballast. The primary coils are also electrically connected so that the ballast may be used as a 120 V ballast.
摘要翻译：在这里描述的多电压镇流器系统的一种形式中，每个初级线圈具有不同的线径，其中最大直径的线被用在120V初级线圈中。在本发明的另一种形式中，一对120V初级线圈与37V初级线圈串联连接，使得镇流器可以用作277V镇流器。初级线圈也电连接，使得镇流器可以用作120V镇流器。

摘要： A low pressure gas discharge lamp ballast circuit is provided for three series-connected low energy gas discharge lamps, in which a first starting capacitor provides a starting voltage to one of the lamps, and a second starting capacitor provides a starting voltage to a second one of the lamps in sequence, so that the ballast losses can be minimized by reducing the ratio of the voltage applied across the three lamp system to the total lamp voltage, while still maintaining the light output and not having to use expensive lamp bases and lampholders.

摘要： A circuit for starting and operating fluorescent lamps from an a-c low frequency power source includes a reactive ballast means connected to ballast the lamps and having a non-linear characteristic for producing a plurality of harmonics of the power source frequency, and a capacitor and a cathode heating transformer connected in series and connected to receive power from said ballast means and resonant in a frequency range encompassing a plurality of said harmonics. This resonant voltage is applied across the lamps to aid the starting of their discharge and thereafter the lamps operate at the a-c power source frequency. The aforesaid resonance frequency range preferably is broad enough to encompass several harmonics of the power source frequency, for example the third through the ninth harmonics (180 to 540 Hz for a source frequency of 80 Hz). Preferably a switch is connected in series with the capacitor and cathode heating transformer for opening the cathode heating circuit when the lamps are operating. This switch may be a bidirectional diode or equivalent voltage sensitive solid state switch, which switches on and off during each half cycle of the lamp starting time period and thus contributes to the harmonic content of the starting voltage waveform.
