Japanese Unexamined Patent Publication No. 2012-113877

The conventional lighting system provided in the above-mentioned emergency lighting device may be electrically connected to an external power source (normal power source) via a switch. The lighting system is powered by an external power source when the switch is on and is no longer powered by an external power source when the switch is off. When the external power supply is cut off by the switch, the lighting system discharges the battery (secondary battery) to perform emergency lighting. In general, a battery deteriorates even when it is discharged. Therefore, every time the external power supply is shut off by the switch, the deterioration of the battery progresses.

The present disclosure is not limited to the following embodiments, and various changes can be made depending on the design and the like as long as the effects of the present disclosure can be achieved.

(1) Outline of disaster prevention lighting equipment The disaster prevention lighting equipment 1 according to the embodiment is an embedded emergency light embedded in an embedded hole provided in the ceiling inside a building. However, disaster prevention lighting equipment is not limited to embedded emergency lights. The disaster prevention lighting fixture may be an exposed emergency light directly attached to the ceiling, or may be a disaster prevention lighting fixture other than an emergency light such as a guide light.

The following embodiments generally relate to lighting systems, disaster prevention lighting fixtures, and disaster prevention lighting systems. In more detail, the following embodiments relate to lighting systems, disaster prevention lighting fixtures, and disaster prevention lighting systems that turn on a light source in an emergency.

FIG. 1 shows a block configuration of the disaster prevention lighting fixture 1 of the present embodiment. The disaster prevention luminaire 1 includes a light source 2, a battery 3, a lighting device 4, and a discharge circuit 5. The lighting device 4 corresponds to the lighting system 4A of the present embodiment.

The light source 2 has a plurality of solid-state light emitting elements. For example, the light source 2 has an LED array in which a plurality of LEDs (Light Emitting Diodes) are connected in series as a plurality of solid-state light emitting elements. The light source 2 is not limited to a configuration having an LED as a solid-state light emitting element. The light source 2 may have other solid-state light emitting elements such as an organic EL (Organic Electro Luminescence, OEL) or a semiconductor laser diode (LD).

The battery 3 is a rechargeable storage battery (secondary battery) and corresponds to an emergency power source. The battery 3 is not limited to a specific type of secondary battery, but the battery 3 is preferably, for example, a nickel-hydrogen battery or a nickel-cadmium battery. Then, when the power failure detection circuit 46 described later detects a power failure of the external power source 9, the battery 3 can output emergency power by discharging the stored electric charge. That is, the power supplied from the battery 3 when the power failure detection circuit 46 detects a power failure of the external power source 9 is the emergency power.

The lighting device 4 includes a charging circuit 40, a lighting circuit 41, and a control circuit 42. The lighting device 4 preferably further includes a notification circuit 43 (notification unit). Further, it is preferable that the lighting device 4 further includes a DC power supply circuit 45, a power failure detection circuit 46, a receiving unit 47, a monitor lamp 48, and a push button switch 49. The lighting device 4 of the present embodiment includes two push button switches 49, and when the two push button switches 49 are distinguished, they are referred to as push button switches 49A and 49B, respectively.

The DC power supply circuit 45 is composed of, for example, a switching power supply circuit such as a flyback converter, and the AC voltage supplied from the external power supply (for example, a commercial power system) 9 is set to a DC voltage lower than the effective value of the AC voltage. It is preferable to convert to. It is preferable that the charging circuit 40 operates when power is supplied from the external power supply 9 and is configured to flow a charging current from the DC power supply circuit 45 to the battery 3. The lighting circuit 41 is preferably configured so that the direct current supplied from the battery 3 is converted into a constant current and supplied to the light source 2.

A switch SW1 such as a breaker is provided in the electric circuit between the external power supply 9 and the lighting device 4. The switch SW1 has a contact that conducts and cuts off an electric circuit. When the switch SW1 is turned on, the electric circuit between the external power supply 9 and the lighting device 4 is conducted, and when the switch SW1 is turned off, the electric circuit between the external power supply 9 and the lighting device 4 is cut off.

The power failure detection circuit 46 is configured to detect a power failure of the external power supply 9 from the output voltage of the DC power supply circuit 45 and notify the control circuit 42. The external power supply 9 is a 100V system or a 200V system commercial power system. The power failure detection circuit 46 detects a power failure when the external power supply 9 is stopped while the switch SW1 is on. Further, the power failure detection circuit 46 detects a power failure if the switch SW1 is turned off even if the external power supply 9 is normal.

The monitor lamp 48 is composed of, for example, a light emitting diode that emits green light. The receiving unit 47 is configured to receive a wireless signal using infrared rays as a communication medium, demodulate a transmission frame from the received wireless signal, and pass it to the control circuit 42. This wireless signal is transmitted from a wireless transmitter operated by an inspector or the like performing the inspection.

The purpose of the inspection is to forcibly operate the discharge circuit 5 to discharge the battery 3 and to confirm at least the degree of deterioration of the battery 3. Inspections include regular inspections and user inspections. The periodic inspection is carried out every period specified by law, and it is checked whether the lighting circuit 41 is forcibly operated, the battery 3 is discharged for a specified time or more, and the floor illuminance by the light source 2 is secured. The purpose is to confirm. The purpose of the user inspection is to forcibly operate the lighting circuit 41, discharge the battery 3 for a short time, and check the degree of deterioration of the battery 3.

In FIG. 1, the discharge circuit 5 is composed of a lighting circuit 41 and a light source 2. That is, the lighting circuit 41 also serves as a part of the discharge circuit 5. Therefore, the lighting device 4 does not need to add a dedicated discharge circuit for inspection, and the configuration can be simplified.

The notification circuit 43 is a notification unit having a notification function, and includes, for example, a monochromatic display element 431, a sounding unit 432 such as a piezoelectric sounder, and a drive circuit 433 that drives the display element 431 and the sounding unit 432. The drive circuit 433 drives the display element 431 to emit light, and drives the sounding unit 432 to produce a sound. The notification circuit 43 may use the monitor lamp 48 as a display element.

The control circuit 42 is configured to have the functions of the lighting control circuit 421, the recording circuit 422, and the notification control circuit 423.

The control circuit 42 operates by being supplied with electric power from an external power source 9, a battery 3, or a control power source. The control circuit 42 preferably includes a computer system. The main configuration of a computer system is a processor and memory as hardware. When the processor executes the program recorded in the memory of the computer system, at least a part of the function as the control circuit 42 in the present disclosure is realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunications line, and may be recorded on a non-temporary recording medium such as a memory card, optical disk, hard disk drive, etc. that can be read by the computer system. May be provided. A processor in a computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). The integrated circuit such as IC or LSI referred to here has a different name depending on the degree of integration, and includes an integrated circuit called a system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). Further, an FPGA (Field-Programmable Gate Array) programmed after the LSI is manufactured, or a logical device capable of reconfiguring the junction relationship inside the LSI or reconfiguring the circuit partition inside the LSI should also be adopted as a processor. Can be done. A plurality of electronic circuits may be integrated on one chip, or may be distributed on a plurality of chips. The plurality of chips may be integrated in one device, or may be distributed in a plurality of devices. The computer system referred to here includes a microcontroller having one or more processors and one or more memories. Therefore, the microcontroller is also composed of one or more electronic circuits including a semiconductor integrated circuit or a large-scale integrated circuit.

The lighting control circuit 421 operates the charging circuit 40 when the power failure detection circuit 46 does not detect a power failure. Further, the lighting control circuit 421 stops the charging circuit 40 and supplies emergency power from the battery 3 to the lighting circuit 41 when the power failure detection circuit 46 detects a power failure. The lighting circuit 41 to which the emergency power is supplied executes emergency lighting for lighting the light source 2 with the emergency power. Further, in the emergency lighting, the charging circuit 40 may be stopped and the lighting circuit 41 may be operated to constantly light the light source 2 (for example, all lighting) regardless of the charging state of the battery 3. Further, if the charge amount of the charging circuit 40 is sufficiently smaller than the discharge amount to the lighting circuit 41 (for example, trickle charging), in the emergency lighting, the charging circuit 40 is not stopped and the lighting circuit 41 is operated to constantly light the light source 2. (For example, all lights may be turned on).

Further, the lighting control circuit 421 determines that an inspection instruction has been given by an inspector or the like when the push button switch 49A is pressed or when the inspection signal transmission frame is received from the receiving unit 47. Then, the lighting control circuit 421 executes an inspection when the battery 3 is in a fully charged state. The lighting control circuit 421 at the time of execution of the inspection stops the charging circuit 40 and supplies the inspection power from the battery 3 to the lighting circuit 41 for a predetermined time. The lighting circuit 41 supplied with the inspection power lights the light source 2 with the inspection power. That is, the lighting control circuit 421 at the time of execution of inspection inspects and lights the light source 2. If the battery 3 is not in a fully charged state, the lighting control circuit 421 first operates the charging circuit 40 to bring the battery 3 into a fully charged state, and then stops the charging circuit 40 for a predetermined predetermined time. In addition, the lighting circuit 41 is operated to discharge the battery 3 for inspection and lighting. Further, in the lighting control circuit 421, if the battery 3 is not in a fully charged state, the charging circuit 40 is operated to charge the battery 3, and the lighting circuit 41 is operated for a predetermined predetermined time to charge the battery. 3 may be discharged. Further, in the inspection lighting, the charging circuit 40 may be stopped and the lighting circuit 41 may be operated to constantly light the light source 2 (for example, all lighting) regardless of the charging state of the battery 3. Further, if the charge amount of the charging circuit 40 is sufficiently smaller than the discharge amount to the lighting circuit 41 (for example, trickle charging), the charging circuit 40 is not stopped and the lighting circuit 41 is operated to constantly light the light source 2 in the inspection lighting. (For example, all lights may be turned on).

When the push button switch 49B is pressed, the lighting control circuit 421 stops the operation of the charging circuit 40, supplies the discharge power of the battery 3 to the lighting circuit 41, and supplies the lighting circuit 41 with the discharge power of the battery 3. Check the emergency lighting to operate for a few seconds.

The discharge circuit 5 is composed of a lighting circuit 41 and a light source 2. The lighting control circuit 421 controls the lighting circuit 41 when the inspection is executed, and discharges the battery 3 by inspecting and lighting the light source 2 using the inspection power that the lighting circuit 41 discharges from the battery 3. The discharge circuit may have a configuration in which the inspection power discharged from the battery 3 is consumed by a resistor or a control power supply. In this case, the inspection power of the battery 3 is consumed even if the light source 2 is not inspected and turned on at the time of inspection.

The recording circuit 422 records the execution status of the emergency lighting and the inspection. The details of the emergency lighting and the execution status of the inspection recorded in the recording circuit 422 will be described later.

The notification control circuit 423 controls the notification circuit 43. The notification circuit 423 causes the notification circuit 43 to perform the inspection execution time, the battery 3 replacement time, the inspection result, and the like.

The notification circuit 43 notifies the execution time of the inspection, the replacement time of the battery 3, and the inspection result. The drive circuit 433 performs notification by lighting or blinking the display element 431 according to the content of notification. Further, the drive circuit 433 may perform notification by outputting voice from the sounding unit 432. The voice output by the sounding unit 432 is a message, a buzzer sound, or the like.

(2) Recording circuit The lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting when the power failure detection circuit 46 detects a power failure. Since the battery 3 is discharged every time the emergency lighting is executed, the deterioration of the battery 3 progresses every time the emergency lighting is executed. Here, the lighting control circuit 421 detects a power failure when the external power supply 9 is stopped while the switch SW1 is on, and when the switch SW1 is turned off even if the external power supply 9 is normal. .. That is, every time the external power supply 9 is shut off by the switch SW1, the deterioration of the battery 3 progresses. For example, when the disaster prevention lighting fixture 1 is installed in a store or the like, there is a usage pattern in which the switch SW1 is turned off when the employee returns home, and the switch SW1 is turned on when the employee works the next sunrise. In such a usage pattern, the switch SW1 is frequently turned off, so that the deterioration rate of the battery 3 becomes high.

Therefore, the recording circuit 422 records the execution status of the emergency lighting and the inspection. It is preferable that the recording circuit 422 mainly includes a processor and a memory as hardware. When the processor executes a program recorded in the memory of the computer system, at least a part of the function as the recording circuit 422 in the present disclosure is realized. For example, in the recording circuit 422, the processor generates emergency lighting and inspection execution status data by executing a program, and stores the generated emergency lighting and inspection execution status data in a memory. The memory is preferably a rewritable non-volatile memory such as an EEPROM (Electrically Erasable Programmable Read Only Memory) or a flash memory.

The power failure detection circuit 46 detects a power failure when the external power supply 9 is stopped while the switch SW1 is on. Further, the power failure detection circuit 46 detects a power failure if the switch SW1 is turned off even if the external power supply 9 is normal. In the recording circuit 422, not only the emergency lighting due to the stop of the external power supply 9 but also the execution status of the emergency lighting due to the switch SW1 being turned off is recorded. Therefore, by referring to the recorded data of the recording circuit 422, the lighting device 4 informs a person of the degree of deterioration of the battery 3, including the deterioration of the battery 3 caused by the external power supply 9 being cut off by the switch SW1. Can be recognized.

(2-1) First Example The recording circuit 422 of the first example records the number of times of emergency lighting and inspection execution as the execution status of emergency lighting and inspection. Therefore, the recording circuit 422 includes a counter 42a as shown in FIG. The counter 42a counts the number of times of emergency lighting and inspection execution. It is preferable that at least a part of the functions of the counter 42a in the present disclosure is realized by the processor executing the program recorded in the memory of the computer system.

Specifically, the counter 42a increments the count value every time the lighting control circuit 421 executes emergency lighting and each time the lighting control circuit 421 executes an inspection. That is, the counter 42a counts the total number of times the emergency lighting is executed and the number of times the inspection is executed.

Then, when the count value (the number of times of emergency lighting and inspection execution) of the counter 42a reaches a predetermined number of notifications, the notification control circuit 423 notifies the notification circuit 43 that it is time to execute the inspection. The number of notifications is, for example, about 10 to several tens. Here, assuming that the life of the battery 3 is 10 years and the inspection is performed twice a year, the number of notifications is preferably 20 times (2 times × 10 years).

Further, when the count value (the number of times of emergency lighting and inspection execution) of the counter 42a reaches a predetermined number of replacements, the notification control circuit 423 notifies the notification circuit 43 that it is time to replace the battery 3. The number of exchanges is larger than the number of notifications, for example, about several tens to 100 times.

FIG. 3 is an example of a three-day time chart of a lighting system including a disaster prevention lighting fixture 1 installed in a store or the like. The time chart of FIG. 3 shows each state of the external power supply 9 and the switch SW1, each execution status of the inspection and emergency lighting by the lighting device 4, and the trigger signal (counter trigger) of the counter 42a. Time t1 is 8:00 on the first day, time t2 is 20:00 on the first day, time t3 is 8:00 on the second day, time t4 is 20:00 on the second day, and time t5 is 8:00 on the third day. Time t6 is 20:00 on the third day, and time t7 is 8:00 on the fourth day.

The employee who came to work at the store on the first day switches the switch SW1 from the off state to the on state at time t1. Since the external power supply 9 is normal, charging of the battery 3 is started at time t1. The employee who has finished the work on the first day switches the switch SW1 from the on state to the off state at time t2 and returns home. When the switch SW1 is turned off at time t2, the power failure detection circuit 46 detects a power failure, and the lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting. The control circuit 42 generates a counter trigger when the emergency lighting is executed (time t2), and the counter 42a increments the count value.

The employee who comes to the store on the second day switches the switch SW1 from the off state to the on state at time t3. Since the external power supply 9 is normal, charging of the battery 3 is started at time t3. The employee who has finished the work on the second day switches the switch SW1 from the on state to the off state at time t4 and returns home. When the switch SW1 is turned off at time t4, the power failure detection circuit 46 detects a power failure, and the lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting. The control circuit 42 generates a counter trigger when the emergency lighting is executed (time t4), and the counter 42a increments the count value.

The employee who came to work at the store on the third day switches the switch SW1 from the off state to the on state at time t5. Since the external power supply 9 is normal, charging of the battery 3 is started at time t5. The external power supply 9 is stopped at time t11 between time t5 and time t6 on the third day, and the power failure detection circuit 46 detects a power failure. When the power failure detection circuit 46 detects a power failure, the lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting. The control circuit 42 generates a counter trigger when the emergency lighting is executed (time t11), and the counter 42a increments the count value.

The inspection is started at time t12 after the time t6 on the third day. When the inspection is started, the control circuit 42 generates a counter trigger (time t12), and the counter 42a increments the count value.

In this way, the counter 42a can count the total number of times the emergency lighting is executed and the number of times the inspection is executed.

(2-2) Second Example The recording circuit 422 of the second example records the number of times the light source 2 is turned off during the execution of the emergency lighting and the inspection as the execution status of the emergency lighting and the inspection. Therefore, the recording circuit 422 includes a counter 42a as shown in FIG. The counter 42a counts the number of times the light source 2 is turned off during emergency lighting and inspection. The lighting control circuit 421 controls the lighting circuit 41 when the emergency lighting is executed, and discharges the battery 3 by executing the emergency lighting. Further, the lighting control circuit 421 controls the lighting circuit 41 when the inspection is executed, and executes the inspection lighting to discharge the battery 3. The remaining capacity of the battery 3 gradually decreases while the emergency lighting or inspection is being performed. Then, when the remaining capacity of the battery 3 decreases to less than a predetermined value, the load current supplied from the lighting circuit 41 to the light source 2 becomes zero, and the light source 2 is turned off. Therefore, the control circuit 42 can determine whether or not the battery 3 is turned off by monitoring the load current. When the control circuit 42 determines that the battery 3 has been turned off during emergency lighting or inspection, the counter 42a increments the count value. That is, the counter 42a counts the number of times the battery 3 is turned off during the emergency lighting or inspection.

Then, when the count value (number of times of turning off) of the counter 42a reaches a predetermined number of notifications, the notification control circuit 423 notifies the notification circuit 43 that it is time to execute the inspection. The number of notifications is, for example, about 10 to several tens. Here, assuming that the life of the battery 3 is 10 years and the inspection is performed twice a year, the number of notifications is preferably 20 times (2 times × 10 years).

Further, when the count value (number of times of turning off) of the counter 42a reaches a predetermined number of replacements, the notification control circuit 423 notifies the notification circuit 43 that it is time to replace the battery 3. The number of exchanges is larger than the number of notifications, for example, about several tens to 100 times.

FIG. 4 is an example of a three-day time chart of a lighting system including a disaster prevention lighting fixture 1 installed in a store or the like. The occurrence timing of the counter trigger in the time chart of FIG. 4 is different from the occurrence timing of the counter trigger in the time chart of FIG.

The employee who has finished the work on the first day switches the switch SW1 from the on state to the off state at time t2 and returns home. When the switch SW1 is turned off at time t2, the power failure detection circuit 46 detects a power failure, and the lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting. When the emergency lighting is started, the light source 2 is turned on and the remaining capacity of the battery 3 is gradually reduced. The emergency lighting is executed over the period T1 after the time t2, the load current becomes zero at the time t21, and the light source 2 is turned off. The control circuit 42 generates a counter trigger when the light source 2 is turned off (time t21), and the counter 42a increments the count value.

The employee who has finished the work on the second day switches the switch SW1 from the on state to the off state at time t4 and returns home. When the switch SW1 is turned off at time t4, the power failure detection circuit 46 detects a power failure, and the lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting. When the emergency lighting is started, the light source 2 is turned on and the remaining capacity of the battery 3 is gradually reduced. The emergency lighting is executed over the period T2 after the time t4, the load current becomes zero at the time t22, and the light source 2 is turned off. The control circuit 42 generates a counter trigger when the light source 2 is turned off (time t22), and the counter 42a increments the count value.

Further, the emergency lighting started at the time t11 on the third day is executed over the period T3 after the time t11. However, since the emergency lighting was terminated before the load current reached zero, the light source 2 was not turned off and the control circuit 42 did not generate a counter trigger. Further, the inspection started at the time t12 on the third day is executed over the period T4 after the time t12. However, since the inspection was completed before the load current reached zero, the light source 2 was not turned off and the control circuit 42 did not generate a counter trigger.

In this way, the counter 42a can count the number of times the light source 2 is turned off during the execution of emergency lighting and inspection. In this case, when the emergency lighting is executed by stopping the external power supply 9 and when the inspection is executed, the discharge of the battery 3 is rarely continued until the load current becomes zero. On the other hand, when the emergency lighting is executed due to the switch SW1 being turned off, the battery 3 is often discharged until the load current becomes zero. Therefore, the lighting device 4 can accurately count the number of times the switch SW1 is turned off by counting the number of times the counter 42a is turned off.

(2-3) Third Example The recording circuit 422 of the third example records the integrated value of the execution time of the emergency lighting and the inspection as the execution status of the emergency lighting and the inspection. Therefore, the recording circuit 422 includes a timer 42b as shown in FIG. The timer 42b integrates the respective time lengths of the emergency lighting and the inspection execution time. Specifically, the timer 42b performs a time counting operation during the period when the lighting control circuit 421 is executing the emergency lighting and the period when the lighting control circuit 421 is executing the inspection, and integrates each time counting time. Record the integrated value of the execution time. It is preferable that at least a part of the functions of the timer 42b in the present disclosure is realized by the processor executing the program recorded in the memory of the computer system.

Then, the notification control circuit 423 notifies the notification circuit 43 that it is time to execute the inspection when the timed value of the timer 42b (the time length of the emergency lighting and the inspection execution period) reaches a predetermined notification value. Let me. The notification value is, for example, about several hours to several tens of hours. Here, assuming that the life of the battery 3 is 10 years, the inspection is executed twice a year, and 30 minutes is required for one inspection, the notification value is 10 hours (0.5 hours x 2 times x). 10 years) is preferable.

Further, the notification circuit 423 informs the notification circuit 43 that it is time to replace the battery 3 when the timed value of the timer 42b (the time length of the emergency lighting and inspection execution period) reaches a predetermined replacement value. Notify. The exchange value is larger than the notification value, for example, about 10 hours to 100 hours.

FIG. 6 is an example of a three-day time chart of a lighting system including a disaster prevention lighting fixture 1 installed in a store or the like.

The employee who has finished the work on the first day switches the switch SW1 from the on state to the off state at time t2 and returns home. When the switch SW1 is turned off at time t2, the power failure detection circuit 46 detects a power failure, and the lighting control circuit 421 controls the lighting circuit 41 to execute emergency lighting. The emergency lighting is executed over the period T1 after the time t2. The timer 42b executes a timekeeping operation over a period T1. In the present embodiment, the integrated value Ta of the execution time at the start of the period T1 is zero.
