Abstract

PROBLEM TO BE SOLVED: To enable a flickering type guide light to be turned off at a spot where specified as well as to provide a protection against overvoltage under no-load. SOLUTION: When a smoke detector 17 detects a smoke, a photo diode of an operation stop circuit 15 emits light, a photo transistor of a flickering stop circuit 12 is turned on, conducts a thyrister, reduces an output voltage of a condenser and stops a flickering of a Xenon lamp 20. When the photo diode illuminates, the photo transistor is turned on, closes a relay contact point of a flickering type guide light device and stops flickering of the Xenon lamp. At the time of inspection, when the Xenon lamp does not light, a breakover element of an output voltage suppression circuit 11 and the thyrister are made conductive, both ends of the condenser are short-circuited by a series circuit of resistor R10, a thyrister Th1 and a resistor R11, and the voltage is reduced. Resistance values of resistors R10 and 11 are selected so as to limit a voltage to give no electrical shock.

2. Description of the Related Art An example of this type of flickering guide light device is disclosed in Japanese Patent Application Laid-Open No. 6-290352 (conventional example). FIG. 4 shows this conventional example of a flashing type guide light device. The flashing type guide light device 3 shown in FIG. 4 stops the flashing of the lamp 20 when detecting smoke such as a fire so as not to guide in the direction in which the fire spreads. Further, a protection circuit 3 for stopping the inverter circuit 10 when an overvoltage occurs at no load.
1 is formed on the input side of the inverter circuit 10.

[0003]

By the way, when the blinking type guide light device provided near the evacuation exit stops the blinking of the lamp in response to the smoke detection signal from the smoke detection device, the evacuation exit and the evacuation passage are closed. It is also desirable to stop the flashing of the flashing type guide light located immediately above the linked floor so that people are not guided to the evacuation exit below the floor where the fire is spreading. For this purpose, it is necessary to send a signal to stop the blinking of the lamp from the blinking guide light device which has stopped the blinking of the lamp to the blinking guide light device provided near the evacuation exit on the floor immediately above. To do so, it is necessary to drive the smoke detection device that has detected the smoke and continue to output the signal, and to continue to output the stop signal of the blinking type guiding light device that has stopped blinking the lamp. A drive power supply for outputting a stop signal is required. 4 does not have this description. Also,
Since the protection circuit 31 stops the inverter circuit 10 when detecting an overvoltage at the time of no load, there is a drawback that the power supply of the operation stop circuit 15 is not supplied. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides protection against overvoltage at no load without stopping an inverter circuit, and also stops a blinking guide light at a place where guidance is to be stopped, such as a floor directly above.

Next, the operation of the present embodiment will be described.

First, in a normal state where no fire or the like has occurred, no emergency signal is input from an automatic fire alarm or the like, so that the relay contact Ry1S is connected to the diode D1 and the battery B1.
Connect. After the AC voltage of the commercial AC power supply E is stepped down by the step-down transformer T1, it is full-wave rectified by the full-wave rectifier circuit Rec1 to charge the battery B1. When the battery is charged, a current flows through the resistor R1 and a potential difference is generated between both ends.
When a current flows through the base and the resistor R2, the transistor Tr
1 turns on. When the transistor Tr1 is turned on, current also flows through the light emitting diode LED1 for charge monitoring via the emitter and collector of the transistor Tr1 and the resistor R3, and the light emitting diode LED1 is turned on. In addition, since power is not supplied to the inverter circuit 10, the xenon lamp 20 does not light.

On the other hand, when a fire is detected by an automatic fire alarm or the like, the battery B1 is activated by the relay coil Ry1L.
The relay contact Ry1S is switched in the direction in which the inverter circuit 10 and the inverter circuit 10 are connected, and the power of the battery B1 is supplied to the inverter circuit 10. Then, the inverter circuit 10
Transistors Tr2 and Tr3 self-oscillate, and a boosted high-frequency AC is induced in the secondary winding T2b of the inverter transformer T2. This high-frequency AC is removed from the DC component by a DC cut capacitor C3, and then rectified by a full-wave rectifier circuit Rec2. The rectification charges the smoothing capacitor C4. When the capacitor C4 is charged,
The voltage between both ends becomes a smoothed DC voltage, which is supplied to the xenon lamp 20 and the resistor R
16, the capacitor C8 and the primary winding T3 of the transformer 3
The capacitor C8 is applied to the series circuit of a and charges the capacitor C8. Further, the voltage is applied to a series circuit of a variable resistor R13 and a resistor R14 and a series circuit of a capacitor C6, a neon lamp NL and a resistor R15 via a resistor R12 of a trigger circuit 23. The capacitor C6 is charged at a rate determined by the time constant of the resistor R12 and the capacitor C6, and the voltage across the capacitor C6 gradually increases. Then, the voltage between the series circuit of the neon lamp NL and the resistor R15 also gradually increases, and the neon lamp NL finally conducts. When the neon lamp conducts, the resistance R
15 is connected in parallel with the series circuit of the variable resistor R13 and the resistor R14, and the connection point of the resistor R12 and the resistor R15, that is,
Since the potential of the gate of the thyristor Th2 of the gate circuit 14 decreases, the voltage between the gate and the anode of the thyristor Th2 increases, and the thyristor Th2 conducts. Thyristor T
When h2 conducts, the capacitor C8 and the primary winding T3a of the transformer T3 are short-circuited, and the capacitor C8 is discharged instantaneously. At this time, a current flows through the primary winding T3a, and as a result, a pulse voltage is induced in the secondary winding T3b. This pulse voltage is applied to the discharge electrode 20a of the xenon lamp 20 to cause the xenon lamp 20 to blink. Capacitor C8
Stops, the current does not flow through the primary winding T3a, so that the xenon lamp 20 does not turn on. Neon lamp NL
Is conducted, the resistor R15 is connected in parallel to the series circuit of the variable resistors R13 and R14, so that the voltage division of the series circuit of the variable resistors R13 and R14 with respect to the resistor R12 is reduced. As a result, the voltage across the capacitor C6 that has been charged before the neon lamp NL becomes conductive becomes higher than the divided voltage of the series circuit of the variable resistor R13 and the resistor R14. As a result, the capacitor C6 is discharged by the series circuit of the variable resistor R13 and the resistor R14 or the resistor R15, and the voltage across the capacitor C6 gradually decreases. Capacitor C6
As the voltage between both ends gradually decreases, the neon lamp NL
The voltage across the series circuit of the resistor R15 and the resistor R15 also decreases, and the neon lamp NL is finally turned off. When the neon lamp NL is turned off, the voltage difference between the gate and the anode of the thyristor Th2 is reduced, so that the thyristor Th2 is turned off. The capacitor C6 of the trigger circuit 13 and the capacitor C8 of the blinking circuit 14 are connected to a smoothing capacitor C4.
Thereafter, the xenon lamp is turned on and off by repeating the above.

When the inverter 10 operates, a high-frequency voltage is generated in the power supply winding T2d provided in the inverter transformer T2. This high-frequency voltage is rectified by a full-wave rectifier circuit Rec3 and smoothed by a smoothing capacitor C9.
7a. When the smoke detector 17 detects smoke, the smoke detector 17 closes the relay contact 17a. Then, a current flows through the resistor R17, and a voltage is generated across the resistor R17. When a voltage is generated at both ends of the resistor R17, a current flows through a series circuit including the emitter and the base of the transistor Tr4 and the resistor R20 to turn on the transistor Tr4. When the transistor Tr4 is turned on, current flows through the photodiode PD1 constituting the photocoupler PC1 and the photodiode PD2 constituting the photocoupler PC2 as the operation stopping means 15, and the photodiode PD1 and the photodiode PD2 emit light.
When the photodiode PD1 emits light, the blink stop circuit 1
The second phototransistor PT1 is turned on to generate a potential at the connection point between the resistor R8 and the resistor R9 and the gate of the thyristor Th1, and the voltage between the gate and the anode of the thyristor Th1 is a voltage for turning on the thyristor Th1. When the thyristor Th1 conducts, both ends of the capacitor C4 are short-circuited by a series circuit of the resistors R10 and R11 and the thyristor Th1, and the resistances of the resistors R10 and R11 are extremely small. And the voltage between the series circuits of the thyristors Th1 drops.
As a result, the neon lamp of the trigger circuit 13 cannot be turned on, so that the xenon lamp 20 is not turned on. When the photodiode PD2 emits light, the phototransistor PT2 is turned on, and the relay contact 17a is closed with respect to the blinking type guide light device, for example, at the place where the guidance of the person is to be stopped, such as the upper floor 18, so that the xenon lamp is turned off. Stop blinking of 20.

When the flashing type guide light device 1 is inspected, the relay contact Ry1S is switched by the inspection confirmation switch in a direction in which the battery B1 and the inverter circuit 10 are connected. The series circuit of the resistor R6 and the resistor R7 of the output voltage suppression circuit 11 divides the voltage across the capacitor C4. Capacitor C
The voltage between the terminals 4 is slightly lower when the xenon lamp 20 is flashing, because power is supplied to the xenon lamp 20, the blinking circuit 14, the trigger circuit 13, and the like. If the xenon lamp 20 is not defective due to disconnection or the like, the capacitor C4 is sufficiently charged, and the voltage between both ends increases. At this time, the voltage across the resistor R7 of the output voltage suppression circuit 11 also increases, and the breakover element of the series circuit of the resistor R9 and the breakover element Z connected in parallel with the resistor R7 conducts. When the breakover element Z conducts, the thyristor Th1 conducts, and both ends of the capacitor C4 are short-circuited by a series circuit of the resistors R10 and R11 and the thyristor Th1. Resistance R1
Since 0 and the resistance value of the resistor R11 are very small,
The voltage between the series circuit of the resistors R10 and R11 and the thyristor Th1 drops, and the resistance values of the resistors R10 and R11 are set so that the voltage does not cause electric shock to humans.

When the blinking stop circuit 15 operates in any blinking type guide light device, the output voltage suppressing circuit 11 also operates to suppress the output voltage of the inverter circuit 10.

Next, a second embodiment of the present invention will be described with reference to FIG.

FIG. 2 is a circuit diagram of a flashing type guide light device according to a second embodiment of the present invention. 2, the same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted.

In FIG. 2, a series circuit of a resistor R6 and a resistor R7, a resistor R8 and a phototransistor PT1 forming a photocoupler PC1 are provided between both ends of a smoothing capacitor C4.
And a series circuit of a resistor R9, a series circuit of a resistor R10 and a thyristor Th1 and a resistor R22, and a connection point of the resistors R6 and R7 and the phototransistor P.
A breakover element Z is connected between the connection point of T1 and the resistor R9.
Is connected, and the connection point between the phototransistor PT1 and the resistor R9 is connected to the gate of the thyristor Th1.
And a capacitor C5 is connected in parallel. Further, the connection point between the cathode of the thyristor Th1 and the resistor R22 is connected to the base of the transistor Tr5.
The base and the emitter of r5 are connected in parallel with the resistor R22, and the collector is connected to the connection point between the neon lamp NL and the gate of the thyristor Th2. The breakover element Z includes a Zener diode, a diac, a constant voltage element, and the like. A series circuit of the resistor R6 and the resistor R7, a series circuit of the resistor R10 and the thyristor Th1 and the resistor R22, a parallel circuit of the breakover element Z, the resistor R9 and the capacitor C5, and a circuit including the transistor Tr5 form the overvoltage suppression circuit 21. doing. Also,
A series circuit of the phototransistor PT1 and the resistor R9 forming the resistor R8 and the photocoupler PC1, a series circuit of the resistor R10 and the thyristor Th1 and the resistor R22, and a circuit formed of the capacitor C5 and the transistor Tr5 form a blink stop circuit 22. I have.

Hereinafter, the operation of the second embodiment of the present invention will be described.

When the smoke detector 17 detects smoke, the relay contact 17a is closed and the photodiode PD constituting the photocoupler PC1 as the operation stopping means 15 is closed.
1 and the photodiode PD2 forming the photocoupler PC2, a current flows, and the photodiode PD1 and the photodiode PD2 emit light. When the photodiode PD1 emits light, the phototransistor PT1 of the blinking stop circuit 22 conducts, and a potential is generated at the connection point between the resistors R8 and R9 and the gate of the thyristor Th1, and the voltage between the gate and the anode of the thyristor Th1 becomes thyristor T1.
It becomes a voltage for conducting h1. When the thyristor Th1 becomes conductive, both ends of the capacitor C4 are short-circuited by a series circuit of the resistor R10, the thyristor Th1, and the resistor 22, and a current flows through this series circuit. Part of this current also flows to the base and the emitter of the transistor Tr5.
Turn on. When the transistor Tr5 is turned on, the gate of the thyristor Th2 of the blinking circuit 14 is short-circuited to the cathode of the thyristor Th2 via the connection point between the neon lamp NL of the trigger circuit 13 and the collector of the transistor Tr5, the collector and the emitter of the transistor Tr5. Connected. As a result, the xenon lamp 20 is not turned on because the thyristor Th2 does not conduct. When the photodiode PD2 emits light, the phototransistor PT2 is turned on, and the relay contact 17a is closed with respect to the blinking type guide light device, for example, at the place where the guidance of the person is to be stopped, such as the upper floor 18, so that the xenon lamp is turned off. Stop blinking of 20.

At the time of inspection of the blinking type induction lamp device 2, if the xenon lamp 20 is not defective due to disconnection or the like, the breakover element Z of the output voltage suppression circuit 21 is turned on. When the breakover element Z conducts, the thyristor Th1 conducts and both ends of the capacitor C4 are connected to the resistor R10 and the thyristor T
It is short-circuited by the series circuit of h1 and the resistor R22. Resistance R
Since the resistance value of the resistor R10 and the resistor R22 is very small, the voltage between the series circuit of the resistor R10 and the thyristor Th1 and the resistor R22 drops, and the voltage of the resistor R10 is set so as not to cause an electric shock to a person. And the resistance value of the resistor R22.
