ENERGIZING ARRANGEMENT FOR A DISCHARGE LAMP |
摘要 |
ENERGIZING ARRANGEMENT FOR A DISCHARGE LAMP The discharge lamp energizing arrangement of this invention comprises a starter and a generator adapted to maintain a discharge current in the lamp. The generator includes a first circuit arranged to couple in series a D.C. voltage source, a first switch and a second switch. When the first switch is closed the second is open and vice versa. A second circuit arranged to couple an inductance and the lamp in series is connected in parallel with the second switch. The switches are operated by a first control means which employs the signals received from an oscillator. The starter includes a third switch connected in parallel with the lamp terminals. Said third switch is operated by a second control means itself operated by the first control means. When the energizing arrangement is turned on the third switch is closed and it subsequently reopens on the first occasion that the first switch passes from the closed to the open state. |
