2. Description of the Related Art An example of a conventional device is shown in FIG. In FIG. 3, power is supplied from the battery 1, the main transistors 15 and 16 start oscillating, a voltage is generated on the secondary side through the transformer 23, and an emergency lamp (more accurately, for continuous lighting). The fluorescent lamp 22 which also serves as a light turns on. This time,
The capacitors 18 and 21 limit the preheating current flowing through the lamp filament of the emergency lamp 22, and the capacitor 19 limits the current flowing through the lamp. If the emergency lamp 22 used here is 20
It is assumed that either a W general fluorescent lamp (hereinafter referred to as a general lamp) or an 18W type so-called energy-saving fluorescent lamp (hereinafter referred to as an energy-saving lamp) in the same class is used. FIG. 2 is a graph showing a luminous flux ratio when a general lamp and an energy saving lamp are turned on and an arbitrary predetermined lamp current is passed. As shown in FIG. 2, the lamp current required to turn on a general lamp and set a certain luminous flux ratio is A. However, instead of using the energy-saving lamp, the lamp current is the same as the above because the same lighting means is used. However, in this case, the luminous flux ratio increases, which may cause a situation in which the standard range is exceeded.
Therefore, it is very difficult to select and use the general lamp and the energy saving lamp.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the device of the present invention will be described below with reference to the circuit of FIG. 1 is a circuit in which electric power is supplied from a battery 1, main transistors 15 and 16 start oscillating, a voltage is generated on a secondary side through a transformer 23, and an emergency lamp (fluorescent lamp) 22 is turned on. It is composed.
The capacitors 18 and 21 limit the preheating current flowing through the lamp filament of the emergency lamp (fluorescent lamp in this embodiment) 22, and the capacitors 19 or 20 are capacitors that limit the lamp current flowing through the emergency lamp 22. is there. The emergency lamp (fluorescent lamp) 22 is assumed to be a 20 W general lamp and an 18 W energy saving lamp. When a general lamp is turned on, an input current flows through the resistor 4 and a voltage is generated across the resistor 4. At this time, the voltage of the Zener diode 3 is input to the − side and the voltage of the resistor 4 is input to the + side of the error amplifier 6, and the voltage of the resistor 4 is set to be slightly lower than that of the Zener diode 3. 6
Since the output of is a L (low) output, the photothyristor 7 does not operate and the transistor 11 remains off. The current flowing through the emergency lamp 22 on the secondary side is the lamp current determined by the capacitor 21. Next, when the energy-saving lamp is turned on, the secondary lamp current is
Therefore, the same lamp current as a general lamp flows.
However, this causes a large load state, and a large amount of input current also flows. Therefore, the voltage generated in the resistor 4 becomes higher than that in the Zener diode 3, the output of the error amplifier 6 becomes H (high) output, the photothyristor 7 operates, and the transistor 11 is turned on. Therefore, the relay 8 is turned on, the secondary side contact is switched to the capacitor 20 side, and the lamp current B is reduced to the lamp current B determined by the capacitor 20 as shown in FIG. For this reason,
The luminous flux ratio is exactly the same as that of a general lamp. In the above embodiment, it is assumed that the general lamp and the energy-saving lamp have the same luminous flux ratio, but conversely, the luminous flux ratio is 50% when the general lamp is inserted, and the luminous flux ratio when the energy-saving lamp is inserted. You can also choose to use 36%.
