に設けである。Reference numeral 13 denotes a preheating transformer provided in parallel with the AC power source 1. A preheating circuit 14 provided in the preheating transformer 13 for detecting the electrodes of the fluorescent lamp 3 is connected to and connected to the short circuit 10 by the relay device 12. It is provided to be selectively switched.
このような構成になる誘導灯の点灯装置は、短絡回路1
0が閉成されている場合は一般の誘導灯と同じであるが

絡回路10を開放し、同時に予熱回路14を閉成させる
。The guidance light lighting device with such a configuration has short circuit 1.
0 is closed, it is the same as a general guide light. However, when the output of the fluorescent lamp 3 is to be reduced during a theater performance, for example, the control device 11 is closed manually, by a timer, or by any other means. is operated to open the short circuit 10 by the relay device 12 and close the preheating circuit 14 at the same time.
従って正性抵抗体9に電流が流れ、そのインピーダンス
が増加し特性によって定まる抵抗値に安定した状態で調
光される。Therefore, current flows through the positive resistor 9, its impedance increases, and the light is dimmed in a stable state at a resistance value determined by the characteristics.
なお、このとき電極には予熱回路14を通じて電流が流

。In addition, even when the light is turned off in this dimming state and then turned on again, the preheating of the electrodes necessary for starting can also be obtained through the preheating circuit 14, so the preheating through the circuit of the glow starter 4 due to the impedance of the positive resistor 9 is performed. Can supplement current.
さらに、正性抵抗体9が冷えた低抵抗時であれば十分に
大きな予熱が得られることは勿論である。Furthermore, it goes without saying that a sufficiently large amount of preheating can be obtained when the positive resistor 9 is cold and has a low resistance.

It is possible to compensate for a drop in the voltage applied to the glow starter 4 due to a voltage drop across the positive resistor 9, thereby ensuring reliable operation during starting.
