[0003] [Patent Document 1] JP 2018-55796 A Summary of the Invention [Problem to be solved by the invention]
[0004] Disaster prevention lighting devices include emergency lights conforming to the Fire Service Act and emergency lights conforming to the Building Standards Act. In general, the inspection cycle for emergency lights is six months, and the inspection cycle for emergency lights is between six and twelve months. A user will inspect the disaster prevention lighting device at the above inspection cycles. On the other hand, the user may inspect the device at a shorter inspection cycle than the above inspection cycles. However, the inspection unit of Patent Document 1 performs a predetermined inspection at a fixed inspection cycle, and the inspection cycle cannot be changed.
[0005] The present disclosure aims to provide a lighting fixture and a lighting control system that are capable of changing the inspection interval. [Means for solving the problem]
[0006] The lighting fixture of the present disclosure comprises a light source and a control device that discharges an emergency power source that turns on the light source and performs an inspection at each inspection period to detect any abnormalities in the emergency power source, and the control device is configured to be able to change the inspection period in response to an external signal. Effect of the Invention
[0007] In the lighting fixture according to the present disclosure, the control device is configured to be able to change the inspection cycle in response to an external signal, and therefore the inspection cycle can be changed. [Brief description of the drawings]
[0008] [Figure 1] 1 is a perspective view of a lighting fixture according to a first embodiment. [Diagram 2] FIG. 2 is a diagram showing the lighting fixture according to the first embodiment in an exploded state. [Diagram 3] 1 is a block diagram of a lighting control system according to a first embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0009] A lighting fixture and a lighting control system according to the present embodiment will be described with reference to the drawings. The same or corresponding components are designated by the same reference numerals, and repeated description may be omitted.
[0010] Embodiment 1 FIG. 1 is a perspective view of lighting fixture 100 according to embodiment 1. FIG. 2 is a view showing a disassembled state of lighting fixture 100 according to embodiment 1. Lighting fixture 100 is, for example, a disaster prevention lighting device such as an emergency exit light or an emergency lighting device, and is attached to a mounting portion such as a ceiling or a wall. An emergency lighting device is also called an emergency light. In this embodiment, lighting fixture 100 will be described taking an emergency lighting device as an example, but the same effect can be obtained even if lighting fixture 100 is an emergency exit light.
[0011] The lighting fixture 100 includes a fixture body 1, a terminal block 10, a mounting bracket 11, a lighting device 3, a storage battery 4, and a light source 2. The lighting fixture 100 charges the storage battery 4 with power supplied from an external power source such as a commercial power source provided outside the lighting fixture 100, and in the event of a power outage or other interruption in the power from the external power source, supplies power from the storage battery 4 to the light source 2 to light the light source 2.
[0012] The fixture body 1 is a housing formed, for example, from a cylindrical sheet metal. The fixture body 1 houses a terminal block 10, a lighting device 3, a mounting bracket 11, a storage battery 4, and a light source 2. The fixture body 1 also houses an inspection switch 5, a receiving unit 6, a transmitting unit 7, a monitor 8, and a setting switch 9, which will be described later. The fixture body 1 need only be able to house the light source 2, the lighting device 3, and the storage battery 4, and is not limited to being cylindrical in shape.
[0013] The terminal block 10 is connected to an electric wire (not shown) connected to an external power source and has a terminal through which power is supplied from the external power source. The terminal block 10 supplies the power supplied from the external power source to the lighting device 3.
[0014] The mounting bracket 11 is provided to fix the terminal block 10 and the lighting device 3 inside the fixture body 1. The terminal block 10 is fixed to the upper part of the mounting bracket 11. The lighting device 3 is fixed to the lower part of the mounting bracket 11. With the terminal block 10 and the lighting device 3 fixed, the mounting bracket 11 is attached to the top surface of the fixture body 1 by a joining member such as a screw.
[0015] The storage battery 4 is attached to the lighting device 3 and serves as a power source for the lighting fixture 100 in an emergency. The storage battery 4 is a rechargeable battery, and is, for example, a secondary battery such as a nickel-cadmium battery, a nickel-metal hydride battery, or a lithium-ion battery, or an all-solid-state battery. The storage battery 4 is charged with power supplied from the external power source 1000 by a charging circuit 32, which will be described later. The storage battery 4 supplies power to the light source 2 via a lighting circuit 33. The storage battery 4 is an example of an emergency power source that lights up the light source 2.
[0016] The light source 2 has a light source unit 21 and an optical control member 22. The light source unit 21 has a light source board on which one or more light emitting elements are mounted. The light emitting element is, for example, an LED (Light Emitting Diode). The light emitting element may be a laser element or an organic EL. The light source unit 21 is electrically connected to the lighting device 3 by a harness or the like, and is turned on by power supply from the lighting device 3. The light source unit 21 is turned on by power supply from the lighting device 3, which uses the storage battery 4 as a power source, in an emergency such as a power outage when the supply of external power is cut off. The optical control member 22 is, for example, a lens. The optical control member 22 is arranged so as to cover the light source unit 21, and controls the light distribution of the light emitted from the light source unit 21.
[0017] The lighting device 3 is electrically connected to the terminal block 10 via an electric wire (not shown). The lighting device 3 converts power supplied from the outside via the terminal block 10, supplies the power to the light source 2, and charges the storage battery 4. The lighting device 3 controls the lighting state of the light source 2 and the charge state and discharge state of the storage battery 4.
[0018] Fig. 3 is a block diagram of lighting control system 500 pertaining to embodiment 1. Lighting control system 500 includes lighting fixture 100 and remote control 200. Next, lighting device 3 will be described in detail with reference to Fig. 3. Lighting device 3 includes power supply circuit 31, charging circuit 32, lighting circuit 33, and control device 34.
[0019] The power supply circuit 31 converts AC power supplied from the external power supply 1000 into DC power. The converted power is supplied to the charging circuit 32 and the control device .
[0020] The charging circuit 32 receives DC power from the power supply circuit 31 and charges the storage battery 4. A secondary battery such as the storage battery 4 gradually loses power over time due to self-discharge. For this reason, the charging circuit 32 may charge the storage battery 4 by trickle charging, which continuously supplies weak power to the storage battery 4. The charging method is not limited to trickle charging, and may be a method of quickly charging the storage battery 4 with power greater than that of trickle charging, such as quick charging. If the storage battery 4 is a battery that is prone to self-discharge, such as a nickel-cadmium battery or a nickel-metal hydride battery, it is preferable to perform trickle charging. On the other hand, if the storage battery 4 is a battery that is not prone to self-discharge, such as a lithium-ion battery or an all-solid-state battery, it is preferable to perform a method of charging when the battery voltage becomes lower than a specified voltage without performing trickle charging. In addition, any device that can store power, such as an electric double layer capacitor, may be used as a substitute for the storage battery 4.
[0021] The lighting circuit 33 discharges the storage battery 4 and supplies power from the storage battery 4 to the light source 2 to light the light source 2.
[0022] The control device 34 can be configured with, for example, a microcomputer having a processing device such as a processor or a CPU (Central Processing Unit). The control device 34 may be configured with a plurality of processing devices. The control device 34 has the functions of a control unit 341, a detection unit 342, an inspection unit 343, a clock unit 344, and a storage unit 345. The control device 34 may be configured to execute a program for causing the processor to execute the functions of the control unit 341, the detection unit 342, the inspection unit 343, the clock unit 344, and the storage unit 345.
[0023] The control unit 341 controls the charging circuit 32 and the lighting circuit 33 to control the lighting state of the light source 2 and the charging state and discharging state of the storage battery 4. The control unit 341 also controls the inspection period stored in the storage unit 345 described later.
[0024] The detection unit 342 detects that the power supplied from the external power source 1000 has been cut off. When the detection unit 342 detects that the power supplied from the external power source 1000 has been cut off, the control unit 341 stops the supply of power from the charging circuit 32 to the storage battery 4 and causes the lighting circuit 33 to supply power from the storage battery 4 to the light source 2 to light the light source 2. Furthermore, when the voltage of the storage battery 4 falls below a predetermined voltage, the control unit 341 stops the supply of power from the storage battery 4 to the light source 2 by the lighting circuit 33. At this time, if power is being supplied from the external power source 1000, the control unit 341 causes the charging circuit 32 to charge the storage battery 4.
[0025] The inspection unit 343 inspects the storage battery 4. The Fire Service Act requires that emergency lights have a 6-month inspection cycle and that the light source 2 can be continuously lit for 20 or 60 minutes using the power supplied from the storage battery 4. The Building Standards Act also requires that emergency lighting devices have a 6- to 12-month inspection cycle and that the light source 2 can be continuously lit for 30 or 60 minutes using the power supplied from the storage battery 4. For this reason, these disaster prevention lights are periodically inspected to see if the required lighting duration is met by turning on the light source 2 using the power from the storage battery 4. Note that the inspection cycle and lighting duration may be changed by law. For this reason, the inspection cycle and lighting duration are not limited to the above values, and may be any that meet the inspection cycle and lighting duration in accordance with the law.
[0026] In this embodiment, there are three patterns of triggers for starting inspection: First pattern: When the time counted by the timing unit 344 described later reaches an inspection cycle stored in the memory unit 345 described later, the inspection unit 343 starts inspection of the storage battery 4. Second pattern: When the user operates the inspection switch 5 described below, the inspection unit 343 starts inspection of the storage battery 4. Third pattern: The user sends an inspection signal to the lighting device 100 from a terminal such as the remote control 200, and the receiving unit 6 described below receives the inspection signal to cause the lighting device 100 to start inspection. In response to the inspection signal, the inspection unit 343 starts inspection of the storage battery 4.
[0027] The inspection unit 343 in this embodiment performs inspection at each inspection period, as in the first pattern, by discharging the storage battery 4 to detect an abnormality in the storage battery 4. That is, the inspection unit 343 automatically performs inspection when the inspection period has elapsed, and repeats displaying the inspection result on the monitor 8, which will be described later, or the like.
[0028] When the inspection unit 343 detects any one of the first to third pattern triggers, the timer unit 344, which will be described later, starts timing. Next, the inspection unit 343 stops charging the storage battery 4 from the charging circuit 32 by the control unit 341, and causes the lighting circuit 33 to supply power from the storage battery 4 to the light source 2 to light the light source 2. The inspection unit 343 compares the voltage of the storage battery 4 with a discharge reference voltage that satisfies the performance required of an emergency lighting device until the time measured by the timer unit 344 reaches the required lighting duration. That is, the inspection unit 343 determines whether the voltage of the storage battery 4 is maintained at or above the discharge reference voltage throughout the lighting duration.
[0029] When the inspection unit 343 finishes the inspection, it stops the supply of power from the storage battery 4 to the light source 2 by the lighting circuit 33. Furthermore, the inspection unit 343 supplies power from the charging circuit 32 to the storage battery 4 and resumes charging of the storage battery 4. The inspection unit 343 notifies the inspection result, for example, by a monitor 8 described later. The inspection unit 343 may transmit the inspection result to an external remote control 200 or the like by a transmission unit 7 described later. Furthermore, the inspection unit 343 stores the inspection result in a memory unit 345 described later.
[0030] The timer unit 344 measures time. In this embodiment, the time counted by the timer unit 344 is the following two items: inspection period and inspection time.
[0031] First, the counting of the inspection period will be described. The inspection unit 343 performs inspection for each inspection period based on the time counted by the timer unit 344. In counting the inspection period, the count is reset, for example, when the power supply to the lighting device 3 starts. That is, the timer unit 344 starts counting, for example, when the external power source 1000 is supplied with power to the lighting device 100. Also, the inspection may be performed in a state where the power supply to the lighting device 100 is not supplied with power. Therefore, the timer unit 344 may determine that the inspection has been performed and start counting when the power supply and non-power supply state from the external power source 1000 to the lighting device 100 changes during a specified period and the non-power supply state is longer than a predetermined time. Even if an actual power outage occurs, the power of the storage battery 4 may be used to determine whether the power has been discharged for a specified time, and the count may be reset as the inspection has been performed.
[0032] Furthermore, in counting the inspection cycle, the count may be reset, for example, at the time of the first inspection and at the time of regular inspection. In other words, timer unit 344 may start counting when an inspection is performed. The first inspection is a self-inspection to check the lighting state after installing lighting fixture 100, and is not a regular inspection associated with an inspection cycle. For this reason, as in the second and third patterns described above, the inspection is started by operating inspection switch 5 or receiving an inspection signal by receiver unit 6.
[0033] Furthermore, when a new building is being constructed, the external power source 1000 may be repeatedly turned on and off. For this reason, a function may be provided to disable resetting the timer unit 344 according to the power supply state of the external power source 1000 when the new building is being constructed.
[0034] Next, counting of the inspection time will be described. When the inspection unit 343 starts the inspection, the timer unit 344 starts counting the inspection time. The inspection unit 343 compares the voltage of the storage battery 4 with the discharge reference voltage until the inspection time counted by the timer unit 344 reaches the required lighting duration. When the inspection ends, the timer unit 344 resets the count of the inspection time.
[0035] The clock unit 344 may be capable of counting real time. There are, for example, two methods for counting real time. The first method is to store calendar information in the storage unit 345 described later, and grasp the real time from the calendar information at the start of counting the real time and the current count. The second method is to receive real time from the outside by the receiving unit 6, and grasp the real time from the received time information and the count of the clock unit 344. The clock unit 344 may also obtain real time from the outside by the receiving unit 6 constantly or periodically. In the control device 34, a start date for starting the count of the inspection cycle may be preset in the storage unit 345. The control device 34 has a calendar function that provides date information by obtaining real time from the outside or counting real time from input calendar information. The clock unit 34 may start counting the inspection cycle when the date information obtained from the calendar function matches the start date, or when the date information obtained from the calendar function has passed the start date.
[0036] The storage unit 345 is, for example, one or more memories having a storage area such as a volatile memory, a non-volatile memory, etc. The storage unit 345 stores the inspection period, the duration of lighting, the inspection result, the number of lighting times, etc. The storage unit 345 may also store a program executed by the processor of the control device 34.
[0037] Next, the inspection period will be described. A storage area is set in the storage unit 345 so that a plurality of inspection periods can be stored. The plurality of inspection periods are, for example, 3 months, 6 months, and 12 months. The inspection period may be any period and is not limited to the above values. As a method for setting the inspection period, for example, one inspection period is set from the plurality of inspection periods stored in the storage unit 345 by the following method.
[0038] The control unit 341 changes the inspection period in response to the operation of the setting switch 9. Specifically, the control unit 341 sets the inspection period when the user presses the setting switch 9. The control unit 341 may change the inspection period in response to the number of times the setting switch 9 is operated. For example, if the current inspection period is set to three months, pressing the setting switch 9 once changes the inspection period from three months to six months, and pressing the setting switch 9 once again changes the inspection period from six months to twelve months. The inspection switch 5 may also function as the setting switch 9. In this case, the inspection period may be set by the number of times the inspection switch 5 is pressed continuously, or by combining a long press for several seconds with multiple presses, etc.
[0039] The method of changing the inspection cycle is not limited to the operation of the setting switch 9. For example, the control unit 341 may change the inspection cycle in response to a setting signal received by the receiving unit 6. Specifically, the inspection cycle may be changed when the user transmits a setting signal for changing the inspection cycle from the remote control 200 and the receiving unit 6 receives the setting signal. The control unit 341 may change the inspection cycle in response to the number of times the receiving unit 6 receives the setting signal. For example, if the current inspection cycle is set to three months, receiving one setting signal from the remote control 200 changes the inspection cycle from three months to six months, and receiving one more setting signal changes the inspection cycle from six months to twelve months.
[0040] The method of changing the inspection interval is not limited to the method of selecting from a plurality of predetermined values as described above, and the inspection interval may be changed to any value.
[0041] The control device 34 may be configured to change the inspection cycle in response to an external signal. When the inspection cycle is changed by the setting switch 9, the signal transmitted to the control device 34 in response to the operation of the setting switch 9 corresponds to the external signal. When the inspection cycle is changed from the remote control 200, the setting signal corresponds to the external signal.
[0042] When the inspection cycle is changed, the monitor 8 issues a notification corresponding to the set inspection cycle. The monitor 8 notifies the user of the inspection cycle, for example, by blinking. For example, if the inspection cycle is set to three months, the monitor 8 blinks once, if it is set to six months, the monitor 8 blinks twice, and if it is set to 12 months, the monitor 8 blinks three times. The user can confirm the set inspection cycle by the blinking of the monitor 8.
[0043] Also, the user may transmit a signal to notify the inspection cycle from the remote control 200, and the receiving unit 6 may receive the signal, so that the monitor 8 may perform a notification corresponding to the set inspection cycle. This allows the user to know the inspection cycle at any time.
[0044] Next, the lighting duration will be described. The lighting duration is basically determined by the type of emergency lighting device and the rated capacity of the storage battery 4. However, the control device 34 may be configured to be able to change the lighting duration in case the lighting duration is changed due to a change in laws and regulations. By setting the lighting duration to a long time, it is expected that the storage battery 4 will be refreshed. The lighting duration can be set in the same way as the inspection period.
[0045] Next, the inspection result will be described. An inspection is performed by the inspection unit 343, and when the inspection is completed, the inspection result is stored in the storage unit 345. The inspection result may be stored in association with real time such as the date and time of the inspection.
[0046] Next, the number of times the light source 2 was turned on will be described. The memory unit 345 stores the number of times the light source 2 was turned on using the power of the storage battery 4 during a power outage or inspection by the inspection unit 343. The memory unit 345 may store the number of times the light source 2 was turned on separately for the number of times the light was turned on due to a power outage and the number of times the light was turned on due to inspection. Furthermore, the memory unit 345 may store the number of times the light source 2 was turned on since the lighting fixture 100 was installed, or may store the number of times the light was turned on due to a power outage during the inspection cycle.
[0047] Next, the inspection switch 5 and the setting switch 9 will be described. Each of the inspection switch 5 and the setting switch 9 is, for example, a push button switch attached to the lighting device 3. The inspection switch 5 and the setting switch 9 are disposed in positions that allow a user to press them from the outside of the fixture body 1. Specifically, the inspection switch 5 and the setting switch 9 are disposed so that the pressed parts are exposed from an opening provided in the fixture body 1. Also, as described above, the inspection switch 5 may also serve as the setting switch 9.
[0048] Next, the receiving unit 6 will be described. The receiving unit 6 is, for example, a remote control light receiving unit that receives an infrared signal from the remote control 200. The receiving unit 6 receives an inspection signal that causes the inspection unit 343 to start inspection, a setting signal that causes the control unit 341 to change the inspection cycle, a signal that causes the lighting duration to be changed, a signal that causes the information stored in the storage unit 345 to be notified, and real-time information, etc. The receiving unit 6 is attached to the lighting device 3. The receiving unit 6 is disposed so as to be exposed from an opening provided in the fixture body 1. Note that any configuration that can receive a signal from the outside via a wired or wireless connection can be adopted as the receiving unit 6.
[0049] Moreover, remote control 200 is an example of a control device that transmits setting signals and the like to receiver 6 of lighting device 100. The control device is not limited to remote control 200, and may be any device such as a terminal such as a smartphone, a control unit, a server, or a computer, and may be connected to lighting device 100 via a network.
[0050] Next, the transmission unit 7 will be described. The transmission unit 7 transmits, for example, an infrared signal to the outside. The transmission unit 7 transmits the inspection results performed by the inspection unit 343 to an external remote control 200 or the like. The information transmitted by the transmission unit 7 may be information stored in the storage unit 345, or may be information such as the inspection results, the time when the inspection was performed, and the number of times the light was turned on. Note that any configuration capable of transmitting information to the outside via a wired or wireless connection may be adopted as the transmission unit 7.
[0051] Furthermore, remote control 200 is an example of a control device that receives and displays the results of an inspection performed at each inspection cycle from transmission unit 7 of lighting fixture 100. The control device is not limited to remote control 200 and may be any device such as a terminal such as a smartphone, a control unit, a server, or a computer, and may be connected to lighting fixture 100 via a network. Furthermore, the control device that communicates with reception unit 6 and the control device that communicates with transmission unit 7 may be different devices.
[0052] Next, the monitor 8 will be described. The monitor 8 is an example of a display unit. The monitor 8 is a display element that displays, for example, the state of the lighting fixture 100. The monitor 8 has, for example, a plurality of LEDs that display different light colors. In this case, for example, a red LED indicates the state of the light source 2, and when the red LED is lit, it indicates an abnormality in the light source 2. The green LED indicates the state of the storage battery 4, and when the green LED is lit, it indicates that the storage battery 4 is normal, when it is blinking, it indicates that the storage battery 4 has reached the end of its life, and when it is off, it indicates that the connection state of the storage battery 4 is abnormal. The orange LED indicates the inspection state of the lighting fixture 100, and when the orange LED is blinking, it indicates that the lighting fixture 100 is being inspected. The relationship between the state of the lighting fixture 100 and the color and lighting state of the monitor is not limited to the above. The state of the lighting fixture 100 may be indicated by the brightness or darkness of the LED.
[0053] Monitor 8 is not limited to an LED, and may be any configuration capable of reporting the status of lighting device 100. For example, monitor 8 may have a screen that displays the status of lighting device 100, or may report the status of lighting device 100 by audio.
[0054] As described above, the monitor 8 notifies the status of the lighting fixture 100, such as the inspection cycle and the duration of illumination. The monitor 8 may notify the results of the inspection performed at each inspection cycle by a means different from that used for other inspection results of the storage battery 4. For example, the monitor 8 may display the results of the inspection performed at each inspection cycle in a color different from that used for the results of the inspection performed by pressing the inspection switch 5 or receiving an inspection signal.
[0055] The monitor 8 may report the number of times that the external power source 1000 has been turned off. For example, when the receiving unit 6 receives a signal commanding to report the number of times that the light source 2 has been turned on due to a power outage, the monitor 8 may report the number of times that the light source 2 has been turned on due to a power outage by the number of times it blinks, etc.
[0056] As described above, the control device 34 of this embodiment is configured to be able to change the inspection interval in response to an external signal, thereby allowing the user to change the inspection interval.
[0057] Next, a first modified example will be described. The inspection unit 343 may disable the control of performing inspection at each inspection cycle in response to a signal from the outside. In other words, the inspection unit 343 may have a mode in which the setting for starting inspection based on the inspection cycle set in the storage unit 345 is cancelled and inspection is started only using the second and third patterns.
[0058] For example, when a predetermined operation is performed on the inspection switch 5, the inspection unit 343 may disable the control of performing inspection at each inspection cycle. The predetermined operation is, for example, operating the inspection switch 5 multiple times. If the inspection switch 5 is a push button switch, the predetermined operation is, for example, pressing the inspection switch 5 a predetermined number of times. The predetermined operation may also be pressing the inspection switch 5 for a predetermined time or longer. The predetermined time is, for example, three seconds.
[0059] Furthermore, when the receiving unit 6 receives a predetermined signal, the inspection unit 343 may disable the control of performing inspection at each inspection cycle. That is, when the user presses a specific button on the remote control 200, the receiving unit 6 receives a signal to change the mode, and the inspection unit 343 disables the control of performing inspection at each inspection cycle. Furthermore, when the receiving unit 6 receives the inspection signal multiple times, the inspection unit 343 may disable the control of performing inspection at each inspection cycle.
[0060] Furthermore, the monitor 8 may notify that the control for performing the inspection is disabled at each inspection cycle. For example, in the case of a mode in which inspection is performed using the first pattern, the monitor 8 may turn on an LED, and when the inspection using the first pattern is disabled, the monitor 8 may turn off the LED. When the inspection using the first pattern is disabled, the monitor 8 may blink the LED.
[0061] Next, a second modified example will be described. When the user changes the inspection cycle, the count of the timer unit 344 may become larger than the set inspection cycle. At this time, it is necessary to determine whether the user should further change the inspection cycle or immediately start inspection. In this case, for example, the monitor 8 issues a notification corresponding to the set inspection cycle and also issues a notification indicating that the count of the timer unit 344 is larger than the set inspection cycle. At this time, the inspection unit 343 provides an arbitrary predetermined grace period such as 30 seconds or 60 seconds. If the user manually starts inspection using the second or third pattern during this grace period, the inspection unit 343 starts inspection. If the user changes the inspection cycle during the grace period, the inspection unit 343 performs control according to the changed inspection cycle. If the user does not take any action during the grace period, the inspection unit 343 automatically starts inspection.
[0062] In this way, when the inspection cycle is changed and the time counted by the timer unit 344 is greater than the changed inspection cycle, if the inspection cycle is not changed again during the grace period and the user does not start inspection, the inspection unit 343 may automatically start inspection after the grace period has elapsed. The grace period is counted, for example, from the time when the inspection cycle is changed.
[0063] Next, a third modified example will be described. The inspection unit 343 may adjust the inspection cycle so that the inspection performed at each inspection cycle is performed in a predetermined time period. The inspection unit 343, for example, compares calendar information including the time period stored in the storage unit 345, the real time counted by the clock unit 344, and the inspection cycle to calculate the time at which the inspection is performed. When the time at which the inspection is performed is not, for example, in the middle of the night, the inspection unit 343 may increase or decrease the length of the inspection cycle so that the inspection starts in the middle of the night. The middle of the night is, for example, from 10 p.m. to 6 a.m. The middle of the night may be after 0:00. The time at which the inspection is performed is not limited to the middle of the night, and may be changed depending on the usage status of the facility in which the lighting fixture 100 is installed, etc.
[0064] This can suppress the discomfort felt by the user when the emergency lighting device, which is normally turned off, is turned on. The transmitting unit 7 may transmit the date and time when the inspection is scheduled to start to the remote control 200, etc. The inspection cycle may also be finely adjusted in hourly units by the setting switch 9, the remote control 200, etc. The adjustment can be performed by the number of times the setting switch 9 is pressed or the number of times a setting signal is transmitted from the remote control 200, etc.
[0065] Next, a fourth modified example will be described. In this embodiment, the inspection switch 5 and the setting switch 9 are provided separately. The inspection switch 5 and the setting switch 9 are an example of a switch section. Only the inspection switch 5 may be provided as the switch section. In this case, the functions of the inspection switch 5 and the setting switch 9 of this embodiment may be realized by only the inspection switch 5, depending on the number of times the inspection switch 5 is pressed, or by pressing and holding the inspection switch 5 for a long time.
[0066] The technical features described in this embodiment may be used in appropriate combination.
