| 摘要 |
The disclosed firing device comprises a fluorescent lamp serially connected to an inductive stabilizer, a first semiconductor switch including an SCR connected across the fluorescent lamp, and a nonlinear dielectric element serially connected to a parallel combination of a PNPN switch as a second semiconductor switch and a discharging circuit across the fluorescent lamp. The discharging circuit may comprise a resistor alone. The first semiconductor switch may include a semiconductor diode and a PNPN switch and the discharging circuit may include a resistor connected across series combination of a semiconductor diode. Alternatively, the discharging circuit may include a Zener diode and a resistor serially interconnected.
