Discharge lamp lighting circuit |
摘要 |
A discharge lamp lighting circuit is provided with a DC power source circuit, a DC-AC conversion circuit, and start circuits. A primary circuit of a transformer in each start circuit has a capacitor and a switch element. When the voltage across the capacitor exceeds a threshold value, or when the switch element has electrical continuity, a high voltage is supplied separately to the discharge lamps from the primary coil through the secondary coil. A common voltage supply circuit supplies the voltage to the primary circuit of each start circuit from the DC power source circuit or the DC-AC conversion circuit.
