Description

TECHNICAL FIELD The present invention relates to an emergency lighting system and lighting device that blinks lighting in conjunction with an alarm operation of an alarm device.

2. Description of the Related Art Conventionally, emergency lighting systems and lighting devices that work in conjunction with residential fire alarms and the like have been known as countermeasures against fires that break out at night.

For example, Patent Literature 1 discloses a lighting system including a remote control device that collects the alarm sound of a residential fire alarm and transmits a lighting signal to the lighting device. Further, Patent Document 2 discloses an emergency lighting system and a lighting device that transmit a wireless signal from a residential fire alarm and turn on when the wireless signal is received.

As described above, in the conventional emergency lighting system, the lighting device is turned on in conjunction with the operation of the alarm that detects the fire. There was a risk that the device alone would not be able to detect the occurrence of a fire. Therefore, a lighting device that performs a blinking operation indicating the occurrence of fire has been studied. Also, in the event of a fire, it is desirable to turn on a plurality of lighting devices and perform a blinking operation for evacuation.

EMBODIMENT OF THE INVENTION Below, embodiment of the emergency lighting system and illuminating device which concern on this invention is described in detail based on drawing. In addition, the present invention is not limited by the following embodiments.

[Basic concept of the embodiment]
First, the basic concept of the embodiment will be explained. Embodiments generally relate to an emergency lighting system with a lighting device that flashes in conjunction with the fire detection of an alarm.

Here, the "alarm device" is installed in a monitoring area such as a general house or a group home, and detects smoke, heat, gas, etc. generated by a fire and gives an alarm. is a concept including, for example, residential fire alarms installed in houses, and furthermore, wireless interlocking alarms in which multiple alarms transmit and receive interlocking signals wirelessly and output interlocking alarms It is a concept that includes Wireless interlocking alarms form an interlocking group with multiple alarms, and an alarm that detects a fire and activates an alarm sends an interlocking signal to other alarms belonging to the interlocking group to activate the alarm. and transmit a fire alarm signal to other equipment such as a lighting device.

A “lighting device” is a device that illuminates a predetermined area (lighting area), for example, a room in a general house or a group home where a lighting device is installed. For example, when a fire breaks out while you are asleep, the lighting device of the present embodiment lights up in conjunction with the fire detection operation of the alarm device to notify the fire and evacuate. This is what makes it possible to assist.

The lighting device of the present embodiment blinks in order to more reliably report a fire when detecting the alarm operation of the alarm device, and when detecting blinking of another lighting device whose lighting area overlaps during blinking. By synchronizing blinking with the other lighting device, it is possible to prevent a photosensitivity attack or the like.

Here, "flashing when the alarm operation of the alarm is detected" means that when the alarm detects a fire and transmits a fire alarm signal to the lighting device, the fire alarm signal is received from the alarm. means to start blinking when Further, in the case where the lighting device is provided with a sound collector for detecting external sound, it means that blinking is started when an alarm sound from the alarm is detected.

Further, there are the following 1 and 2 for the blinking synchronization control for "detecting and synchronizing the blinking of another lighting device whose lighting area overlaps during blinking".

"Blink synchronization control 1" means that the illumination area overlaps during a predetermined turn-off time (T2) of a predetermined blink cycle (T) consisting of a predetermined turn-on time (T1) and a predetermined turn-off time (T2). If it detects the start of lighting in the blinking of another lighting device, it will start lighting in the blinking after a delay (elapsed) by the blinking period (T) from the time of detection of the start of lighting, so that the lighting in the other lighting device The control is synchronized with the blinking of .

Further, "blinking synchronization control 2" means that during a predetermined turn-off time (T2) of a predetermined blink cycle (T) consisting of a predetermined lighting time (T1) and a predetermined turn-off time (T2), the lighting area When detecting the end of lighting in the blinking of another lighting device that overlaps, by starting lighting in blinking after a delay (elapsed) by the extinguishing time (T2) of the blinking cycle (T) from the time of detection of the end of lighting This is a control that synchronizes its own blinking with the blinking of other lighting devices.

In addition, when a predetermined condition for stopping blinking is satisfied during blinking, the lighting device stops blinking for reporting a fire and switches to constant lighting for assisting evacuation.

Here, the "blinking stop condition" is arbitrary, but for example, when the lighting device detects the supply of commercial AC power due to the lighting operation of the lighting switch during blinking, the lighting device stops blinking and switches to constant lighting. be.

Further, when the lighting device detects the alarm sound of the alarm device and starts blinking, and when it detects the stop of the alarm sound from the alarm device, it stops blinking and switches to the constant lighting.

Further, the lighting device may stop blinking and switch to constant lighting when the lighting device is blinking after a predetermined time has elapsed since the start of blinking.

In addition, when the lighting device stops blinking and switches to constant lighting, the lighting state is different from the constant lighting due to operation of the lighting switch during lighting and blinking based on the alarm operation of the alarm. It repeats a pattern such as turning off the light only for a certain period of time.

Further, when a lighting device receives a fire alarm signal indicating a fire source from an alarm corresponding to its own lighting area, the lighting device is in a blinking state indicating a fire source different from that of other lighting devices. It blinks at a blinking cycle that is an integral multiple of the blinking cycle or a fraction of an integer.

In addition, the lighting device includes a main power supply unit that converts commercial AC power that is switched on and off by operating the lighting switch into DC power, and a battery power supply unit that is charged by the commercial AC power supply. While the commercial AC power is stopped by an operation, it operates by the battery power supply, and when it detects the supply of the commercial AC power by the lighting operation of the lighting switch, it switches to the operation by the main power supply.

In addition, when the lighting device detects the alarm operation of the alarm device, the lighting device may blink instead of blinking, and during blinking, the blinking of another lighting device whose lighting area overlaps is detected and synchronized. is. Here, "blinking" means alternately repeating bright lighting and dark lighting, and periodically changing the brightness of the illumination.

Also, the lighting devices of the embodiments are divided into a first lighting device and a second lighting device due to differences in configuration. The first lighting device controls a lighting unit that illuminates a predetermined area, a receiving unit that receives a signal from the outside, a light receiving unit that detects blinking of another lighting device whose lighting area overlaps, and the lighting unit. The lighting control unit starts blinking the lighting unit when the receiving unit receives a fire alarm signal from the alarm, and the lighting area overlaps during blinking. is detected, the flashing is synchronized with that of the other lighting device.

Also, the second lighting device controls a lighting unit that illuminates a predetermined area, a sound collecting unit that detects external sounds, a light receiving unit that detects blinking of another lighting device whose lighting area overlaps, and the lighting unit. The lighting control unit starts blinking of the lighting unit when the sound collecting unit detects the alarm sound from the alarm device, and during blinking, other lighting devices whose lighting areas overlap When blinking is detected, the blinking is synchronized with the other lighting device.

The flashing synchronization control by the lighting control units of the first and second lighting devices is either the above-mentioned flashing synchronization control 1 or 2, or a combination of both.

Specific embodiments will be described below. In the specific embodiments shown below, the "alarm" is a "wireless residential fire alarm", the "lighting device" is provided with an "LED light source", and the "lighting area" is is a room such as a living room, kitchen, or bedroom in a house.

[a. Overview of Emergency Lighting System]
An overview of the emergency lighting system will now be described in more detail. The emergency lighting system of the present embodiment is, for example, installed in a house to monitor a fire, and installation in the house is optional. For example, as shown in FIG. Lighting devices 10 (10-1) to 10 (10-4) and wirelessly linked alarm devices 12 are installed in each room such as a kitchen and a bedroom. Among these, in the living room, two lighting devices 10 (10-1) and 10 (10-2) are installed, and the lighting areas overlap.

Alarms 12 (12-1) to 12 (12-3) are installed in each room such as a living room, a kitchen, and a bedroom of the house 11. FIG. The alarm devices 12(12-1) to 12(12-3) detect a fire and perform an alarm operation, and form an interlocking group. The interlocking group registers a unique group number and alarm device number to the alarm devices 12 (12-1) to 12 (12-3), and also registers the alarm devices 12 (12-1) to 12 (12-3). stores group management information in which alarm device numbers of other alarm devices belonging to its own group are registered. The maximum number of alarm devices forming an interlocking group is determined, for example, the maximum number is 15 units.

For example, when the alarm device 12 (12-1) in the living room detects a fire, an alarm operation is performed to indicate that a fire has occurred by outputting a predetermined voice message and activating the indicator lamp, and the other alarm device 12 ( 12-2) and 12(12-3), a fire interlocking signal indicating that a fire has been detected is transmitted to cause a fire alarm operation.

For this reason, the alarm devices 12(12-1) to 12(12-3) have an interlocking communication function. The interlocking communication function uses the 426Hz band of the communication standard RCR STD-30 as the first frequency band, and transmits a fire interlocking signal indicating that a fire has been detected. Contains the alarm number.

In addition, the alarms 12 (12-1) to 12 (12-3) have an alarm communication function for transmitting fire alarm signals to the lighting devices 10 (10-1) to 10 (10-4). . The fire alarm communication function uses, for example, the 920 MHz band of the communication standard STD-T108 as the second frequency band to transmit fire alarm signals to the lighting devices 10(10-1) to 10(10-4).

Corresponding to the relay communication function of the alarm devices 12 (12-1) to 12 (12-3), the lighting devices 10 (10-1) to 10 (10-4) are also provided with the relay communication function. It is possible to receive a fire alarm signal including a group number and an alarm number transmitted from the alarms 12(12-1) to 12(12-3) using the standard STD-T108 920 MHz band.

[b. alarm]
(b1. Alarm configuration)
The alarm will be explained in more detail. FIG. 2 is an explanatory diagram showing a specific embodiment of the alarm. As shown in FIG. 2, when the alarm device 12 (12-1) detects a fire, it transmits a fire interlocking signal in a first frequency band including a fire signal to other alarm devices, The fire alarm signal is sent to the lighting device 10, and its function and configuration are arbitrary. It is composed of the transfer communication unit 26 . The same applies to the other alarm devices 12 (12-2) and 12 (12-3).

The alarm control unit 14 is composed of a computer circuit having a CPU, a memory, and various input/output ports, and executes predetermined alarm control by executing a program by the CPU.

The sensor unit 16 detects smoke, heat, gas, etc. associated with a fire, and its configuration and function are arbitrary. is intermittently driven to emit light, a received light signal of scattered light received by a light receiving part such as a photodiode is amplified, and a smoke density detection signal is output. Also, a temperature detection section may be provided as the sensor section 16 . The temperature detection unit uses, for example, a thermistor as a temperature detection element, and in this case, outputs a temperature detection signal that is a voltage signal corresponding to a change in resistance value due to temperature.

The notification unit 18 notifies the outside of the fire alarm by sound and light, and has an arbitrary configuration, but for example, it includes an indicator lamp and a speaker. The indicator lamp uses, for example, an LED, and lights up when the alarm device itself detects a fire, and flashes or blinks when a fire interlocking signal including a fire signal is received from another alarm device.

The operation unit 20 has, for example, a test switch and a registration switch. When the test switch is operated while no fire is detected, a predetermined test operation is performed and a predetermined test message is output from the speaker. The test switch also functions as an alarm stop switch during fire alarm output. When the registration switch is operated, group management information in which the group number and the alarm device numbers of other alarm devices are registered is generated by a predetermined registration operation and stored in the non-volatile memory.

The interlocking communication unit 22 is connected to the antenna 24, and communicates fire interlocking signals including fire signals using the 426 MHz band with the other alarm devices 12 (12-2) to 12 (12-3). I do. The alarm communication unit 26 is connected to the antenna 28, and uses the 920 MHz band to transmit various alarm signals including fire alarm signals between the lighting devices 10(10-1) to 10(10-4). communication operation.

(b2. Alarm control unit)
The alarm control unit 14 will be explained in more detail. The alarm control unit 14 reads the smoke concentration detection signal output from the sensor unit 16 after A/D conversion, detects a fire when the smoke concentration is equal to or higher than a predetermined threshold, and performs control to output a fire alarm. .

In addition, when the fire alarm operation is performed, the alarm control unit 14 controls the interlock communication unit 22 to transmit the generated fire interlock signal to other alarm devices using the 426 MHz band. Here, the fire interlocking signal includes the group number and its own alarm number.

In addition, the alarm control unit 14 is in a reception standby state in which a fire reception confirmation signal can be received from another alarm device for a predetermined time starting from the end of transmission of the fire interlocking signal. When the fire reception confirmation signal can be received from all the alarms, the communication operation of the fire interlocking signal is successful, so the communication operation is terminated normally. In this case, since the communication operation of the fire interlocking signal has failed, control is performed to resend the fire interlocking signal.

Further, when the interlocking communication unit 22 receives a fire interlocking signal transmitted by another alarm belonging to the interlocking group, the alarm control unit 14 outputs a fire alarm indicating that the other alarm has detected a fire. In addition to performing control, during a predetermined time starting from the end of transmission of the fire interlocking signal of the other alarm, for example, at the timing of its own order determined according to the alarm number, the group number and the alarm that detected the fire Control is performed to transmit a fire reception confirmation signal indicating that the reception of the fire interlock signal including the unit number has been confirmed for a predetermined period of time.

In addition, the alarm control unit 14 also performs alarm stop control by operating the test switch of the operation unit 20 and fire recovery control in which the smoke density of the sensor unit 16 drops below the threshold, in the same manner as in the case of the fire interlocking signal. 22 transmits an alarm stop interlocking signal and a fire restoration interlocking signal.

In addition, when a fire is detected, the alarm control unit 14, when the transmission of the fire interlocking signal transmitted from the interlocking communication unit 22 using the 426 MHz band is completed or at the idle timing of the suspension of transmission, the alarm communication unit 26 , and controls transmission of a fire alarm signal including a group number and an alarm number that detected a fire to the lighting devices 10 (10-1) to 10 (10-4) using the 920 MHz band.

In addition, when the alarm control unit 14 detects a fire from the smoke concentration detected by the sensor unit 16, the installation location of the alarm itself is the origin of the fire, so in addition to the group number and alarm number, the origin of the fire is indicated A fire alarm signal including an identification code is transmitted to the lighting devices 10(10-1) to 10(10-4).

In addition, the alarm control unit 14, after completing the transmission of the fire alarm signal to the lighting devices 10 (10-1) to 10 (10-4), the lighting devices 10 (10-1) to 10 (10-4) A fire reception acknowledgment signal (ACK) is set in a reception standby state, and if the fire reception acknowledgment signal can be received in this reception standby state, the communication operation of the fire alarm signal is successful, so it is normal termination. When the fire reception acknowledgment signal cannot be received, the communication operation of the fire alarm signal has failed, so control is performed to retransmit the fire alarm signal.

(b3. Externally attached alarm device with transfer communication function)
FIG. 3 is an explanatory diagram showing another embodiment of the alarm device 12 (12-1), and the alarm device 12 (12-1) of this embodiment is characterized by externally attaching a transfer communication function. and The same applies to the other alarm devices 12 (12-2) and 12 (12-3).

As shown in FIG. 3, a transfer communication adapter 260 is provided as a separate device for the alarm device 12 (12-1), and is connected to a transfer terminal 250 from the alarm controller . The transfer communication adapter 260, for example, operates on a battery power supply, and receives instructions from the alarm control unit 14 that has detected a fire, similar to the transfer communication unit 26 of the alarm device 12 (12-1) in FIG. Using the 920 MHz band, control is performed to transmit a fire alarm signal including a group number, an alarm number and a fire source identification code to the lighting devices 10 (10-1 to 10 (10-4).

By externally attaching the transfer communication adapter 260 in this manner, an existing wireless interlocking alarm can be used as an emergency lighting system alarm with a slight modification. Also, even a stand-alone type alarm device without a wireless interlocking function can be used as an alarm device for an emergency lighting system by connecting the transfer communication adapter 260 to the transfer terminal.

[c. lighting device]
The lighting device provided in the emergency lighting system will now be described in more detail. When the lighting device 10 (10-1) detects the alarm operation due to the fire detection of the alarms 12 (12-1) to 12 (12-3), the lighting device 10 (10-1) blinks the lighting to more reliably notify the fire. At the same time, in order to prevent adverse effects on users such as photosensitivity attacks, when the blinking of other lighting devices that overlap the lighting area is detected without exchanging synchronization signals by wireless communication Synchronize blinking with the other lighting device.

(c1. Configuration of lighting device)
The configuration and functions of the lighting device 10 (10-1) are arbitrary, but for example, as shown in FIG. It is composed of a message transfer communication unit 40 and a light receiving unit 44 . The lighting devices 10 (10-2) to 10 (10-4) are similar.

FIG. 5 is a time chart showing flash synchronization control part 1 of two lighting devices 10 (10-1) and 10 (10-2) having overlapping lighting areas installed in the living room of FIG. FIG. 5A shows the case where there is no synchronization deviation from the start of blinking, and FIG. 5(C) shows the case where the illumination device 10 (10-2) starts blinking first and there is a synchronization deviation. Note that the reception timing of the fire alarm signal by the lighting devices 10 (10-1) and 10 (10-2) is temporally There is a case where there is a deviation, and this becomes a factor of synchronization deviation.

FIG. 5A shows that the lighting devices 10 (10-1) and 10 (10-2) simultaneously receive the fire alarm signal at time t1, and the lighting time (T1) and the lighting time (T2) are repeated. The blinking of the blinking period (T) is synchronized with.

It has received a signal and started blinking, causing a synchronization error. In this case, lighting of lighting device 10 (10-1) starts at time t4 during turn-off time T2 of lighting device 10 (10-2) from time t3. Then, the start of lighting at time t4 is detected by the blinking detection signal output from the light receiving section 44 . Therefore, lighting device 10 (10-2) stops blinking until then, and at time t5, which is delayed by blinking period (T) from lighting start time t4 of lighting device 10 (10-1), the lighting time (T1 ) starts blinking for a blinking period (T). As a result, after time t5, the blinking of lighting device 10 (10-2) is synchronized with the blinking of lighting device 10 (10-1).

As a result, after time t5, the blinking of lighting device 10 (10-1) is synchronized with the blinking of lighting device 10 (10-2).

(c6. Synchronous blinking control of three lighting devices 1)
FIG. 6 is a time chart showing flashing synchronization control No. 1 of three lighting devices with overlapping lighting areas. For example, the living room and kitchen shown in FIG. It may be an indoor space, and the lighting areas of the three lighting devices 10 (10-1) to 10 (10-3) overlap. Here, FIG. 6A shows a case where there is no synchronization deviation from the start of blinking of the lighting devices 10(10-1) to 10(10-3), and FIG. 10-1), 10810-2), and 10 (10-3) start blinking in this order to show a case where there is a synchronization deviation, and FIG. , 10(10-2), and 10(10-1) start blinking in the order of 10(10-1).

FIG. 6A shows that the three lighting devices 10 (10-1) to 10 (10-3) simultaneously receive the fire alarm signal at time t1, and the lighting time (T1) and the lighting time (T2 ) is synchronized with the blinking cycle (T).

In FIG. 6B, the lighting device 10 (10-1) receives the fire alarm signal at time t1 and starts blinking, and the lighting device 10 (10-2) receives the fire alarm signal at time t2. At time t3, the lighting device 10 (10-3) receives the fire alarm signal and starts blinking, causing synchronization deviation.

In this case, the start of lighting of lighting device 10 (10-1) is detected at time t6 during the extinguishing time (T2) of lighting device 10 (10-2) from time t4, and lighting from time t5 is detected. At time t6 during the extinguishing time (T2) of the device 10 (10-3), the start of lighting of the lighting device 10 (10-1) is detected. Therefore, the lighting devices 10 (10-2) and 10 (10-3) stop blinking and turn on for the lighting time (T1) at time t7, which is delayed by the blinking period (T) from the lighting start time t6. Start blinking with a blinking period (T) starting from . As a result, after time t7, the blinking of lighting devices 10(10-2) and 10(10-3) is synchronized with the blinking of lighting device 10(10-1).

In FIG. 6C, contrary to FIG. 6B, the lighting device 10 (10-3) receives the fire alarm signal at time t1 and starts blinking, and at time t2, the lighting device 10 (10-3) starts blinking. -2) receives the fire alarm signal and starts blinking, and at time t3, the lighting device 10 (10-1) receives the fire alarm signal and starts blinking, causing synchronization deviation. .

In this case, the start of lighting of the lighting device 10 (10-3) is detected at time t6 during the extinguishing time (T2) of the lighting device 10 (10-2) from time t4. At time t6 during the extinguishing time (T2) of the device 10 (10-1), the start of lighting of the lighting device 10 (10-3) is detected. Therefore, the lighting devices 10 (10-1) and 10 (10-2) stop blinking and turn on for the lighting time (T1) at time t7, which is delayed by the blinking period (T) from the lighting start time t6. Start blinking with a blinking period (T) starting from . As a result, after time t7, the blinking of lighting devices 10(10-1) and 10(10-2) is synchronized with the blinking of lighting device 10(10-3).

Such synchronous flashing control 1 of lighting devices is the same when the number of lighting devices having overlapping lighting areas is four or more.

(c7. Blink stop control)
Further, the lighting control unit 30 detects the supply of operating power from the main power supply unit 32 to which the commercial AC power supplied via the AC line 48 is input by turning on the lighting switch 46 while the lighting unit 38 is blinking. In this case, by stopping the output of the drive pulse signal to the illumination unit 38 and switching to the output of the drive signal, the flashing stop control is performed so that the flashing is stopped and the lighting is always on.

In this way, the lighting device 10 stops blinking and remains lit constantly when the user who has learned of the fire during blinking operates the lighting switch 46, thereby assisting evacuation from the blinking state in which fire notification is prioritized. It is possible to shift to a lighting state that

(c8. Other blink stop control)
In addition, as another blinking stop control, the lighting control unit 30 may perform blinking stop control to stop blinking and switch to constant lighting when a predetermined time has passed since the start of blinking and the light is still blinking. . This is because the warning operation of the alarm and the blinking operation of the lighting device linked to this will allow residents to notice the fire after a certain amount of time, even if they are asleep. It is possible to automatically shift from a flashing state giving priority to fire notification to a lighting state assisting evacuation. Note that the flashing stop control after the lapse of a predetermined time may be provided independently, or may be used together with other flashing stop control.

(c9. Lighting control after stopping blinking)
In addition, when the lighting control unit 30 stops blinking the lighting unit 38 and switches to constant lighting, the lighting control unit 30 switches the lighting unit 38 to constant lighting by the routine lighting operation of the lighting switch 46 (which is turned off) and blinking based on the alarm operation of the alarm device. Lighting control is performed to achieve a lighting state different from that of the lighting state. For example, when the lighting control unit 30 stops blinking of the lighting unit 38 and switches to constant lighting, the lighting control unit 30 repeats lighting for a long time and lighting for a very short time, for example, lighting for 1 minute and lighting for 1 to 2 seconds. Performs lighting control that repeats turning off. This makes it possible to distinguish from the flashing state in which priority is given to normal lighting and fire notification, and to allow the user to recognize that the lighting state is for assisting evacuation.

(c10. Blinking control after elapse of predetermined time)
In addition, when the lighting control unit 30 is operated by the battery power supply unit 34 and is blinking after a predetermined time has elapsed since the start of blinking, the lighting control unit 30 compares the blinking based on the alarm operation of the alarm device 12, and the lighting in the blinking period. A blinking state in which the ratio of time to time is increased may be used. For example, by repeating lighting for a long time and turning off for a very short time, it is possible to recognize that the battery is operating while providing the same usability as in the lighting state. Therefore, it is possible to prevent the lighting device from suddenly turning off due to the dead battery.

(c11. Blinking control to identify fire source)
Further, the lighting control unit 30 of the lighting device 10 (10-1) controls the alarm corresponding to its own lighting area, for example, the alarm 12 (12-1) installed in the same living room shown in FIG. When a fire transfer signal indicating is received, fire source identification blinking control is performed to make a blinking state indicating a fire source different from that of the other lighting devices 10 (10-3) and 10 (10-4) other than the fire source. . The flashing pattern of the fire source identification flashing control by the lighting control unit 30 is arbitrary. The flashing period of is set to 1/2 or 2 times the non-fire flashing period.

As a result, when a plurality of lighting devices blink in conjunction with the alarm operation of the alarm device, the origin of the fire can be easily identified from the difference in the blinking states. In addition, as the blinking state indicating the origin of the fire, by setting the blinking period to be an integer multiple or 1/integer of the blinking period of the other lighting device, it is possible to synchronize with other lighting devices whose lighting areas overlap with each other at a different blinking cycle. enable

[d. Control operation of lighting device]
The control operation of the lighting device will be described in more detail. FIG. 7 is a flowchart showing the control operation of the lighting device 10 (10-1) shown in FIG.

In FIG. 7, the lighting control unit 30 determines whether or not a fire alarm signal has been received from the alarm device in step S1, and when it determines that the fire alarm signal has been received, the process proceeds to step S2, and the lighting unit 38 blinks. Start working. During the blinking operation, if it is determined in step S3 that the light is turned off during the turn-off time (T2) of the blinking period (T), the process proceeds to step S4, and lighting starts from the blinking detection signal of the other lighting device output from the light receiving unit 44. is detected, the process proceeds to step S5, and lighting is started with a delay of the blinking period (T) from the time when the lighting start is detected, thereby synchronizing its own blinking with the blinking of other lighting devices.

Subsequently, when it is determined in step S6 that the supply of commercial AC power by lighting operation of the lighting switch 46 is determined from the supply of operating power from the main power supply section 32, the process proceeds to step S7, and the supply of operating power is switched from the battery power supply section 34 to the main power supply. Then, in step S8, the flashing operation of the illumination unit 38 is stopped and switched to constant lighting.

Subsequently, in step S9, when the fire source is determined from the fire alarm signal received by the fire alarm communication unit 40, the flow proceeds to step S10, and the constant lighting operation is performed in a predetermined flashing pattern indicating the fire source.

Subsequently, in step S11, stoppage of supply of commercial AC power due to turning off operation of lighting switch 46 is determined from stoppage of output of operating power from main power supply unit 32, output of drive signal to lighting unit 38 is stopped, and lighting is performed. is turned off, the operation power is supplied from the battery power supply unit 34, and the process returns to step S1.

[e. Flashing synchronization control part 2]
The flash synchronization control 2 by the illumination control unit 30 of the illumination device 10 (10-1) of FIG. 4 will be described in more detail.

The blinking synchronization control 2 by the lighting control unit 30 turns on the other lighting device 10 (10-2) whose lighting area overlaps during a predetermined turn-off time (T2) of the blinking cycle (T) during the blinking operation. When the end of the lighting is detected, lighting is started after a delay of the turn-off time (T2) of the blinking period (T) from the detection of the end of lighting, thereby controlling the blinking of the lighting device to synchronize with the blinking of other lighting devices. .

FIG. 8 is a time chart showing blink synchronization control 2 by two lighting devices 10 (10-1) and 10 (10-2) having overlapping lighting areas. In FIG. 8A, at time t1, lighting device 10 (10-1) receives the fire alarm signal and starts blinking, and at time t2, lighting device 10 (10-2) starts blinking. It received the fire alarm signal and started blinking, causing a synchronization error. In this case, lighting of lighting device 10 (10-2) ends at time t4 during turn-off time T2 of lighting device 10 (10-1) from time t3. Then, the end of lighting at time t4 is detected by the blinking detection signal output from the light receiving section 44 .

Therefore, the lighting device 10 (10-1) stops blinking, and the lighting device 10 (10-2) stops lighting at time t5, which is delayed by the turn-off time (T2) of the blinking period (T) from the lighting start time t4. , the blinking of the blinking period (T) starting from the lighting of the lighting time (T1) is started. As a result, after time t5, the blinking of lighting device 10 (10-1) is synchronized with the blinking of lighting device 10 (10-2).

FIG. 8(B) is a time chart showing flash synchronization control part 2 by three lighting devices 10 (10-1), 10 (10-2), and 10 (10-3) having overlapping lighting areas. . In FIG. 8B, at time t1, lighting device 10 (10-1) receives the fire alarm signal and starts blinking, and at time t2, lighting device 10 (10-2) fire alarm signal. The lighting device 10 (10-3) receives the signal and starts blinking, and at time t3, the lighting device 10 (10-3) receives the fire alarm signal and starts blinking, causing a synchronization deviation.

In this case, lighting device 10 (10-2) ends lighting at time t5 during the turn-off time (T2) of lighting device 10 (10-1) from time t4. Since the lighting of (10-3) continues, the lighting end of lighting device 10 (10-2) is masked, and the lighting end is not detected by lighting device 10 (10-1).

Subsequently, lighting of lighting device 10 (10-3) ends at time t6, and this lighting end is detected by lighting devices 10 (10-1) and 10 (10-2). Therefore, the lighting devices 10 (10-1) and 10 (10-2) stop blinking and turn on at time t7, which is delayed by the turn-off time (T2) of the blink cycle (T) from the lighting start time t6. Flashing of the flashing period (T) starting from the lighting of time (T1) is started. As a result, after time t7, the blinking of lighting devices 10(10-1) and 10(10-2) is synchronized with the blinking of lighting device 10(10-3).

Such synchronous flashing control 2 of lighting devices is the same when the number of lighting devices having overlapping lighting areas is four or more. Further, the lighting control unit 30 may have control functions for both the above-described blinking synchronization control 1 and blinking synchronization control 2 . In this case, when the end or start of lighting due to blinking of another lighting device is detected during the extinguishing time (T2), the former is delayed by the blinking period (T), and the latter is delayed by the blinking period (T). After a delay of the extinguishing time (T2), the blinking of the blinking period (T) starting from lighting is started, thereby synchronizing with the blinking of other lighting devices.

The sound collector 50 detects an external sound, and its configuration and function are arbitrary. It outputs a detection signal to the illumination control section 30 .

With the provision of the sound collector 50, the lighting controller 30 outputs a driving pulse signal to the lighting unit 38 when the alarm sound from the alarm device is detected from the external sound detection signal from the sound collector 50. to control blinking.

In addition, when the lighting control unit 30 detects that the alarm sound from the alarm has stopped from the external sound detection signal from the sound collector 50 during the blinking control, the lighting control unit 30 stops blinking and switches to constant lighting. control. Other controls including blinking synchronization control are the same as those of the lighting device 10 (10-1) in FIG. 4, so description thereof will be omitted.
