(Embodiment)
[Constitution]
First, the structure of the illumination system which concerns on embodiment is demonstrated. FIG. 1 is an external view of a device included in a lighting system according to an embodiment.

  As illustrated in FIG. 1, the lighting system 100 includes one or more lighting devices (the lighting device 10 and the lighting device 10 a) and an information terminal 30. In FIG. 1, the lighting system 100 includes two lighting devices, but it is sufficient that the lighting system 100 includes at least one lighting device.

  The lighting system 100 is a system for managing the degree of deterioration of a storage battery included in each of one or more lighting devices arranged in a building, for example. In the illumination system 100, voltage value information indicating the output voltage value of the storage battery is managed as a parameter for managing the degree of deterioration. Specifically, each of the plurality of lighting devices (the lighting device 10 and the lighting device 10a) transmits voltage value information of a storage battery included in the lighting device to the information terminal 30. Thereby, the voltage value information is stored in the information terminal 30. Each of the plurality of lighting devices is, for example, a guide light, but may be another lighting device such as an emergency light. In other words, the lighting system 100 is a disaster prevention lighting system.

  Next, the functional configuration of the illumination system 100 will be described. FIG. 2 is a block diagram illustrating a functional configuration of the lighting system 100. In addition, since the function structure of the some illuminating device contained in the illuminating system 100 is substantially the same, only the illuminating device 10 is illustrated in FIG. Since the illumination device 10a has the same functional configuration as that of the illumination device 10, the description thereof is omitted.

[Lighting device]
First, a detailed configuration of the illumination device 10 will be described with reference to FIG. In the embodiment, the illuminating device 10 is a guide light that emits light in order to make the user recognize the location of the illuminating device 10 (guide light) in a normal state and emits light to guide an emergency exit in an emergency. That is, it is necessary for the lighting device 10 to continue to emit light in both normal and emergency situations.

  The illumination device 10 includes a power conversion unit 11, a switching unit 12, a detection unit 13, a lighting circuit 14, a light source 15, a storage battery 16, a charging unit 17, a first control unit 18, and a first communication unit. 19, a timer unit 20, and a first storage unit 21. In FIG. 2, the power system 40 is also illustrated. The power system 40 is an example of an external power source provided outside the lighting system.

  The power conversion unit 11 converts AC power obtained from the power system 40 into DC power, and outputs the DC power obtained by the conversion to the switching unit 12 and the charging unit 17. Specifically, the power conversion unit 11 is a power conversion circuit including a rectifier circuit including a diode bridge, a DC-DC converter circuit, and the like.

  The switching unit 12 switches between supplying power from the power system 40 to the light source 15 or supplying power charged in the storage battery 16 to the light source 15. The switching unit 12 is a switching circuit that operates based on a detection signal obtained from the detection unit 13. Note that when the inspection control is performed by the first control unit 18, the switching unit 12 is controlled by the first control unit 18.

  The switching unit 12 electrically connects the output of the power conversion unit 11 and the input of the lighting circuit 14 at normal times. As a result, electric power (DC power) that is electric power from the electric power system 40 and converted by the electric power converter 11 is output to the lighting circuit 14. That is, the switching unit 12 supplies the power from the power system 40 to the light source 15 via the power conversion unit 11 and the lighting circuit 14.

  On the other hand, the switching unit 12 electrically connects the output of the storage battery 16 and the input of the lighting circuit 14 in an emergency. Thereby, the power (DC power) charged in the storage battery 16 is output to the lighting circuit 14. That is, the power charged in the storage battery 16 is supplied to the light source 15 via the lighting circuit 14. Specifically, the switching unit 12 is a switching circuit using a switching element or a relay element.

  The normal time means when the detection unit 13 does not detect the stop of the power from the power system 40, that is, when the power is normally supplied from the power system 40. The abnormal time means when the detection unit 13 detects the stop of the power from the power system 40 (from the time when the power from the power system 40 is stopped until the supply of the power is resumed). .

  The detection unit 13 detects the stop of power from the power system 40. The detection unit 13 outputs, for example, a detection signal (digital signal) that becomes a high level when the stop of the power from the power system 40 is detected and becomes a low level when the power from the power system 40 is normally supplied. It is a power failure detection circuit. The above-described switching unit 12 operates based on such a detection signal.

  The lighting circuit 14 converts the power output from the switching unit 12 into DC power suitable for the light source 15 and outputs it. The lighting circuit 14 is a switching power supply circuit including a semiconductor switching element, for example.

  The light source 15 emits light by power obtained from the power conversion unit 11 (power system 40) or the storage battery 16 via the lighting circuit 14. The light source 15 is, for example, an LED module having LEDs as light emitting elements, but may be a light emitting module using other light emitting elements such as organic EL or inorganic EL. The light source 15 emits white light, for example, but may emit light of other colors.

  The storage battery 16 is a power source that supplies power to the light source 15. The storage battery 16 is used as an emergency power source, for example, when the supply of power from the power system 40 is stopped. The storage battery 16 is, for example, a nickel metal hydride battery. The storage battery 16 may be a storage battery that can be charged and discharged, and may be a lithium ion battery or a lead storage battery.

  The charging unit 17 is power from the power system 40 and charges the storage battery 16 with power (DC power) after being converted by the power conversion unit 11. That is, the charging unit 17 charges the storage battery 16 using the power from the power system 40. The charging unit 17 is realized by a charging circuit, for example.

  The charging unit 17 trickle-charges the storage battery 16 using the power from the power system 40 during normal times, that is, while the power from the power system 40 is supplied to the light source 15 by the switching unit 12. Even when the storage battery 16 is in a fully charged state, the amount of charge is reduced by natural discharge over time. Trickle charging is a charging method in which charging is always performed with a minute current in order to compensate for the amount of charge that is reduced by spontaneous discharge. According to trickle charging, the storage battery 16 is always fully charged.

  Moreover, the charging part 17 performs the charge after discharge is completed in the inspection control mentioned later. Unlike the trickle charge, this charge is a normal charge performed with a larger current than the trickle charge. During this charging, the first control unit 18 controls the switching unit 12 so that the output of the power conversion unit 11 is electrically connected to the input of the lighting circuit 14. For this reason, the light source 15 emits light during lighting control even if the storage battery 16 is charged.

  The first control unit 18 mainly controls charging and discharging of the storage battery 16. Specifically, the first control unit 18 discharges the storage battery 16 and then causes the charging unit 17 to charge the storage battery 16. The voltage value indicating the output voltage value of the storage battery 16 when the storage battery 16 is fully charged. Control is performed to transmit information to the first communication unit 19. Hereinafter, such control is also referred to as inspection control.

  When discharging the storage battery 16 in the inspection control, the first control unit 18 controls the switching unit 12 to electrically connect the output of the storage battery 16 and the input of the lighting circuit 14. In other words, the storage battery 16 is electrically connected to the load. Thereby, the electric power charged in the storage battery 16 is consumed by the light emission of the light source 15. That is, the storage battery 16 is discharged. The discharging is performed, for example, until the capacity of the storage battery 16 becomes zero.

  Further, the first control unit 18 causes the charging unit 17 to charge the storage battery 16 after the discharge of the storage battery 16 is completed. And the 1st control part 18 detects the output voltage value of the storage battery 16 when it becomes fully charged by this charge, and makes the 1st communication part 19 transmit the voltage value information which shows the detected output voltage value.

  The voltage value information is information directly indicating the detected output voltage value, for example, “2.1V”, but the initial value of the detected output voltage value, for example, “80%”. It may be a ratio (ratio) to (output voltage value at the beginning of introduction of the storage battery 16). When the voltage value information is a ratio of the detected output voltage value to the initial value, the first storage unit 21 stores the initial value, and the first control unit 18 generates the initial value when generating the voltage value information. Perform an operation using.

  In addition, the 1st control part 18 produces | generates the date information which shows the date and time (date and time when voltage value information was transmitted) in which lighting control was performed based on the date and time measured by the timer part 20, and produces | generates the produced | generated date information. You may make it transmit to the 1st communication part 19. FIG.

  The first control unit 18 as described above is realized by, for example, a processor, a microcomputer, or a dedicated circuit, but may be realized by a combination of a processor, a microcomputer, and a dedicated circuit. The specific mode of the first control unit 18 is not particularly limited.

  The first communication unit 19 transmits the voltage value information generated by the first control unit 18 to the second communication unit 31 by wireless communication. When the lighting system 100 includes a plurality of lighting devices, the first communication unit 19 may further transmit the ID of the lighting device having the storage battery 16 that is the detection target of the voltage value information. Moreover, the 1st communication part 19 may transmit the date information which shows the date when inspection control was performed.

  Moreover, the 1st communication part 19 receives the instruction | indication of lighting control (trigger signal for starting lighting control) from apparatuses arrange | positioned outside the illuminating device 10, such as the information terminal 30, by radio | wireless communication. Specifically, the first communication unit 19 is a communication module (communication circuit) for wireless communication. The wireless communication may be radio wave communication or optical wireless communication. Radio wave communication is communication using an electromagnetic wave having a longer wavelength than infrared rays, and optical wireless communication is communication using an electromagnetic wave having a wavelength between infrared rays and visible light.

  The timer unit 20 measures time. For example, the timer unit 20 measures the current date and time (including date). The timer unit 20 is specifically a timer circuit or a real-time clock IC, but may be in any form. Time information indicating the time measured by the timer unit 20 is output to the first control unit 18. The timer unit 20 is used for periodically performing lighting control.

  The first storage unit 21 is a storage device that stores a control program executed by the first control unit 18 when the first control unit 18 includes a processor or the like. The first storage unit 21 may store the ID of the lighting device 10, the initial value of the output voltage value of the storage battery 16, and the like. Specifically, the first storage unit 21 is realized by a semiconductor memory or the like.

[Information terminal]
Next, the detailed configuration of the information terminal 30 will be described with reference to FIG. The information terminal 30 is a device that manages voltage value information of the lighting device 10. In the embodiment, the information terminal 30 is a tablet terminal, but may be a smartphone or a personal computer. The information terminal 30 may be a server device. The information terminal 30 includes a second communication unit 31, a second control unit 32, a second storage unit 33, a display unit 34, and an input reception unit 35.

  The second communication unit 31 receives the voltage value information transmitted by the first communication unit 19. When the lighting system 100 includes a plurality of lighting devices, the second communication unit 31 also receives the ID of the lighting device having the storage battery 16 that is the detection target of the received voltage value information. Further, the second communication unit 31 transmits a lighting control instruction to the first communication unit 19 of the lighting apparatus 10 based on the control of the second control unit 32. Specifically, the second communication unit 31 is a communication module (communication circuit) for wireless communication. The wireless communication may be radio wave communication or optical wireless communication.

  The second control unit 32 stores the voltage value information received by the second communication unit 31 in the second storage unit 33. When the lighting system 100 includes a plurality of lighting devices, the second control unit 32 stores the voltage value information received by the second communication unit 31 in the second storage unit 33 in association with the ID of the lighting device. To do. When the second control unit 32 further stores the voltage value information of the lighting device 10 in a state where the voltage value information of the lighting device 10 is already stored in the second storage unit 33, the voltage value information of the lighting device 10 is stored. It may be updated (overwritten).

  Further, the second control unit 32 determines whether or not the output voltage value indicated by the voltage value information received by the second communication unit 31 is lower than a predetermined value. As shown in FIG. 3, even when the storage battery 16 is not particularly used (when only trickle charging is performed), the storage battery 16 gradually deteriorates over time and the output voltage value decreases. FIG. 3 is a schematic diagram showing a decrease in the output voltage value. 3 indicates the ratio of the output voltage value to the initial value (the output voltage value at the beginning of the introduction of the storage battery 16).

  It can be said that the decrease in the output voltage value indicates the degree of deterioration (life reduction) of the storage battery 16. It can be said that the lower the output voltage value, the higher the degree of deterioration (deterioration progresses). Therefore, the second control unit 32 outputs notification information when it is determined that the voltage value information received by the second communication unit 31 is lower than a predetermined value.

  The notification information is information for notifying the user that the storage battery 16 has deteriorated. The notification information is, for example, image information and is output to the display unit 34. As a result, since an image as shown in FIG. 4 is displayed on the display unit 34, the lighting system 100 can notify the user that the storage battery 16 has deteriorated. FIG. 4 is a diagram illustrating an example of an image displayed based on the notification information.

  When the information terminal 30 is a server device or the like, the notification information may be transmitted to other information terminals (such as a tablet terminal or a smartphone) other than the information terminal 30. In this case, the second control unit 32 outputs the notification information to the second communication unit 31, and the second communication unit 31 transmits the notification information to another information terminal.

  In addition, the predetermined value used for the determination by the second control unit 32 may be an absolute voltage value (for example, 2.1 V) indicated by the unit [V]. When the output voltage value (voltage value information) at the beginning of introduction of the lighting device is stored in the second storage unit 33 as an initial value, the initial value × predetermined ratio (for example, 60%, etc.), a value that differs for each lighting device It may be.

  The second control unit 32 as described above is realized by, for example, a processor, a microcomputer, or a dedicated circuit, but may be realized by a combination of a processor, a microcomputer, and a dedicated circuit. The specific mode of the second control unit 32 is not particularly limited.

  The 2nd memory | storage part 33 is a memory | storage device with which voltage value information is matched and memorize | stored with ID of an illuminating device, date information, etc. Information in which the voltage value information is associated with the illumination device ID and date information is also referred to as deterioration level information. The second storage unit 33 stores the control program executed by the second control unit 32 and information on the predetermined value used for the determination by the second control unit 32 (for calculating the initial value, the predetermined value, and the predetermined value). Parameters such as a predetermined ratio used) are also stored. Specifically, the second storage unit 33 is realized by a semiconductor memory or the like.

  The display unit 34 displays an image based on the notification information (image information) output by the second control unit 32. The display unit 34 displays an image as shown in FIG. 4 based on the notification information, for example. Specifically, the display unit 34 is realized by a liquid crystal panel, an organic EL panel, or the like.

  The input reception unit 35 is a user interface that receives user input. For example, the input receiving unit 35 receives an input for starting lighting control from the user. Then, the second control unit 32 causes the second communication unit 31 to transmit a lighting control instruction. The transmitted lighting control instruction is received by the first communication unit 19 of the lighting device 10.

  Moreover, the input reception part 35 receives the input for displaying the deterioration degree of the storage battery 16 from a user. Then, the second control unit 32 refers to the deterioration degree information stored in the second storage unit 33, and displays an image indicating the deterioration degree of the storage battery 16 as shown in FIG. 5 based on the referenced deterioration degree information. It is displayed on the display unit 34. FIG. 5 is a diagram illustrating an example of an image indicating the degree of deterioration of the storage battery 16. In FIG. 5, a list of deterioration levels of a plurality of storage batteries is displayed. The degree of deterioration is expressed as a ratio [%] of the output voltage value of the storage battery 16 to the initial value.

  The input receiving unit 35 is specifically a touch panel, but may be a keyboard and a mouse when the information terminal 30 is a personal computer.

[Operation example 1 of lighting device]
Next, an operation example 1 when the lighting device 10 performs inspection control will be described with reference to a flowchart. FIG. 6 is a flowchart of the operation example 1 of the lighting device 10.

  In the operation example 1, the first control unit 18 periodically performs the inspection control based on the time measured by the timer unit 20. Inspection control is performed during normal times and not during emergencies. Therefore, the operation example 1 is premised on the normal time.

  As described above, during normal operation, the charging unit 17 trickle-charges the storage battery 16 (S11). At this time, the first control unit 18 determines whether or not a predetermined time has elapsed since the last inspection control based on the time measured by the timer unit 20 (S12). The predetermined time is, for example, 6 months, but is not particularly limited.

  If it is determined that the predetermined time has not elapsed (No in S12), the first control unit 18 continues the determination until the predetermined time has elapsed (S12). When it is determined that the predetermined time has elapsed (Yes in S12), the first control unit 18 discharges the storage battery 16 (S13). Specifically, the first control unit 18 first stops trickle charging by the charging unit 17. And the 1st control part 18 discharges the storage battery 16 by supplying the electric power charged by the storage battery 16 to the light source 15 by controlling the switching part 12. FIG. In other words, the first control unit 18 controls the switching unit 12 to electrically connect the output of the storage battery 16 and the input of the lighting circuit 14, thereby discharging the storage battery 16. For example, the first control unit 18 discharges the storage battery 16 until the storage amount becomes 0, but may discharge the storage battery until the storage amount decreases to some extent.

  Next, the 1st control part 18 makes the charging part 17 charge the storage battery 16 (S14). Unlike the trickle charge performed in step S11, this charge is a normal charge performed with a larger current than the trickle charge.

  When the storage battery 16 is fully charged, the first control unit 18 detects the output voltage value of the storage battery 16 (S15). Next, the 1st control part 18 produces | generates the voltage value information which shows the detected output voltage value, and transmits the produced | generated voltage value information to the 1st communication part 19 (S16).

  As described above, in the illumination system 100, the inspection control is periodically performed, and the voltage value information transmitted by the inspection control is stored in the information terminal 30. That is, the lighting system 100 can manage the voltage value information as the degree of deterioration. In addition, if inspection control is performed periodically as described above, it is not necessary to manually inspect the lighting device 10.

[Operation example 2 of lighting device]
Next, an operation example 2 when the lighting device 10 performs inspection control will be described with reference to a flowchart. FIG. 7 is a flowchart of the operation example 2 of the lighting apparatus 10.

  In the operation example 2, the first control unit 18 performs the inspection control based on the lighting control instruction received by the first communication unit 19. In the following description of the operation example 2, the description overlapping with the operation example 1 is omitted as appropriate.

  The charging unit 17 trickle-charges the storage battery 16 (S11). At this time, the first control unit 18 determines whether the first communication unit 19 has received a lighting control instruction (S17).

  If it is determined that the first communication unit 19 has not received the lighting control instruction (No in S17), the first control unit 18 continues the determination until the first communication unit 19 receives the lighting control instruction. (S17). The first control unit 18 performs the lighting control (S13 to S16) when it is determined that the first communication unit 19 has received the lighting control instruction (Yes in S17). The lighting control is the same as in Operation Example 1.

  In addition, although the instruction | indication of lighting control is transmitted by the 2nd communication part 31 when the input reception part 35 with which the information terminal 30 is provided receives a user's input, for example, other information terminals or the illumination apparatus 10 It may be transmitted by a dedicated remote controller or the like.

  Thus, the inspection control may be performed based on a user instruction. Further, the operation example 1 and the operation example 2 may be combined. That is, in principle, the inspection control is performed periodically, but may be performed when there is an instruction from the user.

[Operation example of information terminal]
Next, an operation example of the information terminal 30 will be described with reference to a flowchart. FIG. 8 is an example of a flowchart of the operation of the information terminal 30.

  First, the 2nd communication part 31 with which the information terminal 30 is provided receives the voltage value information transmitted by the 1st communication part 19 in the said step S16 (S21). The second control unit 32 stores the voltage value information received by the second communication unit 31 in the second storage unit 33 (S22).

  Next, the second control unit 32 determines whether or not the output voltage value indicated by the voltage value information (voltage value information stored in the second storage unit 33) received by the second communication unit 31 is lower than a predetermined value. Is determined (S23). As described above, since the voltage value information and the information related to the predetermined value are stored in the second storage unit 33, the second control unit 32 refers to the second storage unit 33, thereby performing step S <b> 23. Judgment can be made.

  When it is determined that the output voltage value indicated by the voltage value information received by the second communication unit 31 is greater than or equal to the predetermined value (No in S23), the operation of the information terminal 30 ends. When it is determined that the output voltage value indicated by the voltage value information received by the second communication unit 31 is lower than the predetermined value (Yes in S23), the second control unit 32 determines that the storage battery 16 has deteriorated. Notification information for notification is output (S24).

  For example, if the notification information is output to the display unit 34, an image as shown in FIG. 4 is displayed on the display unit 34. If the notification information is output to the second communication unit 31 and transmitted to the other information terminal by the second communication unit 31 as the output destination, an image as shown in FIG. 4 is displayed on the display unit of the other information terminal. Is displayed.

  If deterioration level information including voltage value information is stored in the second storage unit 33 as in step S22, an image as shown in FIG. 5 can be displayed on the display unit. With such an image, the user can recognize the degree of deterioration of the storage battery 16.

  If the notification information is output as in step S24, an image as shown in FIG. 4 can be displayed on the display unit. With such an image, the user can recognize the deterioration (replacement time) of the storage battery 16.

  Note that the output of the notification information may be performed in stages. For example, if the predetermined value described in FIG. 8 is the first predetermined value, the second control unit 32 further causes the output voltage value indicated by the voltage value information received by the second communication unit 31 to be greater than the first predetermined value. It may be determined whether or not the value is lower than the low second predetermined value. When the notification information described in FIG. 8 is the first notification information, when it is determined that the output voltage value indicated by the voltage value information received by the second communication unit 31 is lower than the second predetermined value, You may output the 2nd notification information for notifying that the storage battery 16 has deteriorated. In this case, the second notification information is notification information different from the first notification information, and is information for performing a notification with higher urgency than the first notification information.

[Effects]

The lighting device 10 includes a light source 15, a storage battery 16 that supplies charged power to the light source 15, a first communication unit 19, a charging unit 17 that charges the storage battery 16, and a first control unit 18. The first control unit 18 discharges the storage battery 16, charges the storage battery 16 to the charging unit 17, and outputs the voltage value information indicating the output voltage value of the storage battery 16 when the storage battery 16 is fully charged by the charging. Control (inspection control) to be transmitted to the unit 19 is performed.
