DISCHARGE LAMP OPERATING CIRCUIT |
摘要 |
<p>DISCHARGE LAMP OPERATING CIRCUIT A lamp operating circuit comprising a DC power source, an inventor including step-up transformer inductance windings and a controlled transistor switch connected across the output of the DC source, and a high frequency oscillator coupled to the transistor switch for operating the same at predetermined intervals. A low wattage HID lamp is connected across the inverter through a ballast capacitor series connected to one terminal of the lamp and a ballast inductance coupled in series with the other lamp terminal. The ballast inductance and ballast capacitor are selected to resonate sinusoidally at a frequency having a half period coinciding with the on-time of the transistor.</p> |
