The present disclosure relates to a lighting system, a power supply device, a lighting fixture, a mapping method, and a program.
Immediately after mounting, at installation positions on a ceiling of a building, lighting fixtures that turn on and off by receiving a plurality of control signals, a relation between identification information of each of the lighting fixtures and position information indicating the position of the lighting fixture is not clear, and lighting of each of the lighting fixtures cannot be controlled. For this reason, mapping is carried out, which is a work of associating the identification information and the position information of a plurality of lighting fixtures using a terminal device.
Patent Document 1 discloses a lighting system comprising a plurality of lighting fixtures and a setting device for instructing a dimming degree of each of the plurality of lighting fixtures to enable dimming.
In a case where mapping is performed using a terminal device in a conventional lighting system, when an operator selects identification information of lighting fixtures displayed on a screen of a terminal device, since the lighting fixture corresponding to the selected identification information blinks, the operator goes near the blinking lighting fixture. Then, the operator confirms a position of the lighting fixture and touches a mark of the corresponding position in an arrangement plan of the lighting fixtures to perform an association between identification information and position information. At this time, since the number of installed lighting fixtures increases in one office with a large room area, it takes time for the operator to confirm the positions of the lighting fixtures. Further, in a case of acquiring identification information of the lighting fixtures using a wireless signal from the terminal device in a large-scale lighting system installed in a commercial facility such as a shopping mall having an open ceiling, identification information of the lighting fixtures installed in a different floor may also be often acquired by the terminal device, and it takes time to confirm whether mapping is required for the light fixtures on the present floor.

In
The lighting control controller 30 is arranged in the same room as the plurality of lighting fixtures 12. The lighting control controller 30 acquires association information, which is mapping information of the lighting fixtures 12, between the identification information and position information of the lighting fixtures 12, from the terminal device 40, and performs lighting control of the lighting fixtures 12 after completion of pairing with the lighting fixtures 12. The lighting control controller 30 can be a remote controller having an operation unit that allows a user to operate the lighting. The lighting control controller 30 wirelessly controls the lighting fixture 12 from the lighting control controller 30 by a control signal from the terminal device 40 and a schedule function stored therein.
The communication unit 15 is an interface used for the lighting fixture 12 to wireless communicate with the lighting control controller 30. The communication unit 15 includes a wireless transceiver.
The control unit 16 controls the communication unit 15 and the power conversion unit 14. The control unit 16 transmits information stored in the storage unit 17, which will be described below, to the terminal device 40 via the communication unit 15 and the lighting control controller 30 according to an operation signal received from the terminal device 40 via the lighting control controller 30 and the communication unit 15. The control unit 16 includes, for example, a CPU, and arithmetic processing is executed by a program stored in the storage unit 17. Further, the control unit 16 causes the communication unit 15 to transmit to the terminal device 40 the identification information and information measured and acquired by the measurement unit 18 as described below.
The storage unit 17 is realized by a ROM such as an EEPROM, a RAM, an HDD, or a flash memory, for example. The storage unit 17 has a function of storing the received operation signal and information acquired by the measurement unit 18 to be described below.
The measurement unit 18 measures information based on a predetermined operation or a predetermined action. When a predetermined detection is made, the measurement unit 18 stores the information measured by the measurement unit 18 in the storage unit 17. The “predetermined operation” is, for example, an on or off operation of a switch. The “information” is, for example, any one of an energizing time, a non-energizing time, the number of times of zero crossing of the input voltage, and the number of on/off times of the power in the lighting fixture 12. As will be described in another example of the embodiment described below, the “information” may be a combination of any two or more of the energizing time, the non-energizing time, the number of times of zero crossing of the input voltage, and the number of on/off times of the power in the lighting fixture 12, or may be obtained by adding time-series information to such a combination. The “energizing time” is a time until the power is supplied to the power supply device 13 and the power is cut off. The “non-energizing time” is a power-off time when the power supply is quickly switched from off to on within a predetermined time (for example, within 2 seconds) in an energized state of the power supply device 13. Hereinafter, the switching from power-off to power-on may be described as an “off-on operation”. The “predetermined detection” is, for example, detection of power cutoff. For example, when the power cutoff is detected, the power supply device 13 stores the information measured by the measurement unit 18 in the storage unit 17. The number of number of on/off times of the power supply may be measured by a counter provided inside the measurement unit 18. The number of on/off times of the power supply may be the “number of power supply times” that the power is supplied to the power supply device 13 within a predetermined time, which is a short time, or may be the “number of power cutoff times” that the power is cut off in a short time. Further, the information may be information that is not be measured by the measurement unit 18, and the information such as the time and the number of times may be measured by the control unit 16. During an off-on operation of the lighting fixture 12 in a short time, the output of the power conversion unit 14 of the power supply device 13 is stopped and the light source unit 20 is turned off, but the power supply to the control unit 16 is maintained for a time of about 10 seconds, for example, and the control unit 16 actuates. An input voltage detection unit of the power supply device 13 is not shown.
An example of a predetermined action for the measurement unit 18 to start measuring the information includes the following action. First, as a power supply action, the input voltage of the power supply device 13 is detected by a circuit, and the control unit 16 is actuated by a control power supply at the time of power cutoff after about several seconds. For example, the above action is performed by performing the off-on operation of the power supply device 13 quickly (within about 2 seconds) in an energized state. Further, the above action may be performed by repeatedly performing the off-on operation of the power supply device 13 quickly (within about 2 seconds) three times in an energized state.
The storage unit 17 may be in an initial state in which there is no data in the storage unit 17 when the power is supplied. An example of the action for initializing the storage unit 17 may include a case where the communication unit 15 receives a specific signal or a case where the off-on operation of the power supply is repeated quickly (within about 2 seconds) five times.
In addition, when the communication unit 15 receives a specific signal as the predetermined action of the communication unit 15, the measurement unit 18 may start measuring information.
Further, as the predetermined action of the control unit 16, the above power supply action is performed to cut off the power supply once, and the control unit 16 starts to actuate as a measurement mode when the next power is supplied after a sufficient time (for example, about several tens of seconds) has passed, and may cause the measurement unit 18 to start measuring the information.
When the power supply device 13 performs a series of actions of the power supply and the power supply cutoff to the control unit 16 from outside one or more times by the predetermined operation, the storage unit 17 may store, as information, at least one of the energizing time, the non-energizing time, the number of times of zero crossing of the input voltage, and the number of on/off times of the power in the lighting fixture 12.
The light source unit 20 emits illumination light when electric power is supplied. For example, the light source unit 20 is an LED, a fluorescent lamp, or a halogen lamp.
The terminal device 40 and the lighting control controller 30 are communicably connected to each other, and the lighting control controller 30 and the lighting fixture 12 are communicably connected to each other, by specific low power wireless communication using a frequency in 920 MHz band or 2.4 GHz band, or wireless communication such as BLE (Bluetooth (registered trademark) Low Energy), Wi-Fi (registered trademark), or Bluetooth (registered trademark).
The terminal device 40 is, for example, a tablet PC or a smartphone having a function of transmitting and receiving signals and a display screen. The terminal device 40 is a setting device that performs mapping which is an association of the identification information of each of the lighting fixtures 12 with the position information of the lighting fixtures 12 within the room. The lighting fixture 12 is paired with the lighting control controller 30 by such mapping, and thus lighting control can be performed by the lighting control controller 30.
The terminal device 40 includes an operation display unit 41, a communication unit 42, a control unit 43, and a storage unit 44. The operation display unit 41 corresponds to a display unit. The operation display unit 41, for example, includes a touch panel screen which is a display screen. The operation display unit 41 has a function of an input unit that receives a user's operation and a function of displaying marks indicating installation positions of the plurality of lighting fixtures 12 and the identification information of the plurality of lighting fixtures 12. When the operation display unit 41 is operated so as to associate the identification information of the lighting fixtures 12 displayed on the terminal device 40 with the mark, the control unit 43 stores in the storage unit 44 the association between the identification information and the position information of the lighting fixture 12 represented by the mark. The terminal device may be configured to have the display unit and the operation unit separately.
The communication unit 42 is an interface for the terminal device 40 to wirelessly communicate with the lighting fixture 12 via the lighting control controller 30.
The control unit 43 has a function of controlling the communication unit 42 and a function of controlling a display state of the operation display unit 41. The control unit 43 includes, for example, a CPU, and arithmetic processing is executed by a program stored in the storage unit 44.
The storage unit 44 is realized by a ROM, a RAM, an HDD, or a flash memory, for example. The storage unit 44 stores an application program for actuating the control unit 43. By causing the control unit 43 to execute a mapping program as an application program, the user can cause the operation display unit 41 to display a screen for mapping the lighting fixture 12. The mapping program can be read by the terminal device 40, and is executed such that the terminal device 40 classifies the plurality of lighting fixtures 12 based on the information acquired by each of the plurality of lighting fixtures 12 and causes the operation display unit 41 to display them. When the mapping program is executed, the terminal device 40 displays an arrangement plan of the plurality of lighting fixtures 12 and the identification information of the plurality of lighting fixtures 12 on the operation display unit 41.
Next, a mapping method of the lighting system 10 will be described.
Thereby, in step S14, the plurality of lighting fixtures 12 transmit the identification information to the lighting control controller 30, and the lighting control controller 30 transmits the identification information to the terminal device 40. In step S16, the terminal device 40 transmits the signal requesting the stored information to the lighting control controller 30 for the acquired identification information of the plurality of lighting fixtures 12. The lighting control controller 30 transmits the signal to request the transmission of the information to the plurality of lighting fixtures 12 having the corresponding identification information.
Thus, in step S18, the plurality of lighting fixtures 12 transmit the acquired information to the lighting control controller 30, and the lighting control controller 30 transmits such information to the terminal device 40. At this time, the respective switches S1, S2, and S3 shown in
Table 1 indicates an example of the energizing times of the switches S1, S2, and S3, and the energizing times of the switches S1, S2, and S3 are different from each other.
Table 2 indicates an example of a relation between the identification information (ID) and the energizing time of each of the lighting fixtures 12.
As indicated in Table 2, the energizing times of the switches S1, S2, and S3 may be slightly different from the energizing times of the plurality of lighting fixtures 12 connected to the same switches S1, S2, and S3. The reason is because, for example, a timing of current input and current cutoff may vary between the plurality of lighting fixtures 12 connected to the same switches, due to the influence of capacitors inside the lighting fixtures 12.
Based on the predetermined operation described above, each of the lighting fixtures 12 measures, for example, the energizing time as information with the measurement unit 18, and stores the energizing time measured by the measurement unit 18 in the storage unit 17 when the predetermined detection described above is performed. Each of the lighting fixtures 12 transmits the acquired energizing time to the terminal device 40.
Returning to
On the other hand,
As shown in
Next, as shown in step S22 of
In
Then, as shown in step S24 of
Further, according to the operation of the association of the terminal device 40 by the user, the association between the identification information and the position information of the lighting fixture 12 is stored in the storage unit 44, and the information of the association is transmitted to the lighting control controller 30 at the same time. Such mapping work is performed on all the identification information displayed on the operation display unit 41. The lighting control controller 30 can control the lighting of the plurality of lighting fixtures 12 after the mapping work for all the identification information is completed and the pairing with the lighting fixture 12 is completed. It may be possible to perform setting such that the lighting, the lights-out, and dimming of each of the lighting fixtures 12 can be individually controlled by the selection operation of the lighting fixtures 12 by the terminal device 40.
In the above description, the case of classifying the identification information has been described when the distribution of the plurality of groups of the lighting fixtures 12 corresponding to the plurality of switches S1, S2, and S3 is divided without intersecting as in the example shown in
According to the lighting system 10, the power supply device 13, the mapping method, and the program described above, it is possible to shorten the work time when the plurality of lighting fixtures 12 are mapped using the terminal device 40. Specifically, the terminal device 40 displays, based on the information from the lighting fixture 12, the identification information of the plurality of lighting fixtures 12 connected to the same switch as one group. At this time, it is highly possible that the plurality of lighting fixtures 12 connected to the same switch are arranged close to each other. Thereby, the identification information of the same group corresponds to the plurality of lighting fixtures 12 in close positions. For this reason, when the terminal device 40 selects the identification information of the same group, the plurality of lighting fixtures 12 whose actual positions are close to each other are blinked to specify the position, so that the work time of the mapping can be shortened. For example, since the lighting fixtures 12 of the group 1 are connected by the same first switch as the identification information L3, when the operator performs the association of the mark of another lighting fixture 12 of the group 1 after performing the association of the identification information L3, the operator may confirm the lighting fixture 12 blinking near the lighting fixture 12 having the identification information L3. This makes it possible to perform the mapping work efficiently.
Further, when the lighting system 10 is installed in a commercial facility or the like such as a shopping mall having an open ceiling, it is conceivable that the terminal device 40 acquires the identification information from the lighting fixtures 12 installed on different floors when the identification information from the lighting fixtures 12 are acquired from the terminal device 40 using a wireless signal.
In the case of this example, since the terminal device 40 can group the close lighting fixtures 12 connected to the same switch on the same floor to display the lighting fixtures 12 even in this case, based on the information acquired from the lighting fixtures 12, it is possible to shorten the work time of mapping without taking time to confirm whether the lighting fixtures 12 on the present floor require mapping.
In this example, when the terminal device 40 selects the identification information of the lighting fixture 12, the lighting fixture 12 is blinked, but the present invention is not limited thereto, and the lighting fixture 12 may be darkened or brightened to cause a change in dimming, and may be distinguished from another lighting fixture 12.
Further, as the information to be measured by the measurement unit 18, the case has been described where the identification information of the lighting fixtures 12 is classified by the energizing time, but the identification information of the lighting fixtures 12 may be classified using, as the information, any one of the non-energizing time of the lighting fixture 12, the number of times of zero crossing of the input voltage, and the number of on/off times of the power supply.
Further, the case has been described above where the terminal device 40 communicates with the plurality of lighting fixtures 12 via the lighting control controller 30, but the terminal device 40 may be configured to communicate directly with the plurality of lighting fixtures 12 by a wireless signal without the lighting control controller 30.
By execution of a mapping program of the terminal device 40, a command signal for causing the lighting fixture 12 to store information is transmitted to the plurality of lighting fixtures 12 via the lighting control controller 30. Thus, the plurality of lighting fixtures 12 store the information in the storage unit 17 (
For example, as indicated in Table 3, a case is considered where different data items are transmitted from the lighting control controller 30 to the plurality of lighting fixtures 12 through the first to third control lines 50 to 52. Each data item indicated in Table 3 represents a hexadecimal number. In each data item, X indicates an arbitrary value.
At this time, as indicated in Table 4, Corresponding data are transmitted to the lighting fixtures 12 having identification information, respectively.
In this case, when the communication unit 15 (
According to the configuration of this example, it is highly possible that the lighting fixtures 12 connected by the same control lines 50 to 52 are installed nearby, in terms of cost and the like. Thereby, when the identification information of the same group is selected in the terminal device 40, the plurality of lighting fixtures 12 whose actual positions are close to each other are blinked to specify the position, so that the work time of the mapping can be shortened. In this example, other configurations and operations are the same as those of
At this time, the relation between the number of off-on times and the energizing time of each of the lighting fixtures 12 is indicated in Table 6.
Then, the terminal device 40 acquires the energizing time and the number of off-on times from each of the plurality of lighting fixtures 12, and first classifies the identification information of the lighting fixtures 12 with the number of off-on times. Next, with the same number of off-on times, the acquired energizing times are sorted in ascending order to be lined up from the minimum value to the maximum value, the group number, which is the number of sections, is increased from 1, and the number of elements for each group is calculated. At this time, when there is a distribution of the information and the elements are separated by the information when the number of elements becomes 0, the lighting fixtures 12 are divided and grouped by the separated information. When the elements are not separated, the lighting fixtures 12 are set to one group. In the distribution of the information, when distributions having a plurality of peaks are duplicated, some of the lighting fixtures 12 are duplicated in a plurality of groups and are grouped. When the association between the identification information and the position information of the duplicated lighting fixtures 12 is completed, the duplicated lighting fixtures 12 are deleted from the display of the other group.
For example, in the case of Table 6, the number of off-on times is 1 for identification information L1 to L10, and the number of off-on times is 2 for identification information L11 to L25. At this time, in the lighting fixtures 12 of the identification information L1 to L10 connected to the first switch S1, the number of off-on times is 1, and the distribution of the energizing time can be treated as the same group, which is set to a group 1.
In the lighting fixtures 12 of the identification information L11 to L25 connected to the second switch S2 and the third switch S3, the number of off-on times is two, which is the same, and there is only one peak in the distribution of each of the first and third energizing times during the power-on. On the other hand, in the lighting fixtures 12 of the identification information L11 to L25, there are two peaks, including a peak before and after 1 second and a peak before and after 2 seconds, in the distribution of the second energizing time during the power-on. For this reason, the lighting fixtures 12 having the second energizing time of about 1 second are referred to as group 2, and the lighting fixtures 12 having the second energizing time of about 3 seconds are referred to as group 3.
In the configuration of this example as described above, the terminal device 40 acquires information obtained by adding time-series information to a combination of the energizing time and the number of power-on times of the lighting fixtures 12, and classifies the plurality of lighting fixtures 12 based on such information. Thereby, the types of information acquired by the terminal device 40 are increased, whereby the accuracy of grouping the lighting fixtures 12 can be improved, and accordingly, the work time of the mapping can be shortened. In this example, other configurations and operations are the same as those of
In the above configuration, the case has been described where the measurement unit 18 measures the “information” obtained by adding the time-series information to the combination of the energizing time and the number of power-on times of the lighting fixtures 12, but the present invention is not limited thereto, and the above “information” may be information obtained by adding the time-series information to the combination of two or more of the energizing time, the non-energizing time, the number of times of zero crossing of the input voltage, and the number of on/off times of the power in the lighting fixture 12.
Next, the lighting system of another example of the embodiment will be described. A basic configuration of the lighting system of this example is the same as the configuration of
In the case of this example, the power supply device 13 of each of the lighting fixtures 12 measures the energizing time for each power-on, the number of off-on times, and a cumulation of the energizing times (cumulative energizing time); that is, a total energizing time when the off-on operation is performed in a short time; that is, when the power is turned on from the power-off operation, using the measurement unit 18 (
Then, the terminal device 40 acquires the energizing time, the number of off-on times, and the cumulative energizing time from each of the plurality of lighting fixtures 12, and first classifies the identification information of the lighting fixtures 12 with the number of off-on times. Next, with the same number of off-on times, the acquired energizing times are sorted in ascending order to be lined up from the minimum value to the maximum value, the group number, which is the number of sections, is increased from 1, and the number of elements for each group is calculated. At this time, when there is a distribution of the information and the elements are separated by the information when the number of elements becomes 0, the lighting fixtures 12 are divided and grouped by the separated information. When the elements are not separated, the lighting fixtures 12 are set to one group.
For example, in the case of Table 7, the number of off-on times is 1 for identification information L1 to L10, and the number of off-on times is 2 for identification information L11 to L25. At this time, in the lighting fixtures 12 of the identification information L1 to L10 connected to the first switch S1, the number of off-on times is 1, and the distribution of the energizing time can be treated as the same group, which is set to a group 1.
In the lighting fixtures 12 of the identification information L11 to L25 connected to the second switch S2 and the third switch S3, the number of off-on times is two, which is the same. On the other hand, in the lighting fixtures 12 of the identification information L11 to L25, there are two peaks, including a peak before and after 5 seconds and a peak before and after 7 seconds, in the distribution of the cumulative energizing time. For this reason, the lighting fixtures 12 having the cumulative energizing time of about 5 seconds are referred to as group 2, and the lighting fixtures 12 having the cumulative energizing time of about 7 seconds are referred to as group 3. Thereby, the terminal device 40 can classify the plurality of lighting fixtures 12 based on the information acquired from the lighting fixtures 12.
In the configuration of this example as described above, the terminal device 40 acquires, as information, a combination of the energizing time, the number of power-on times, and the cumulative energizing time of the lighting fixtures 12, and classifies the plurality of lighting fixtures 12 based on such information. Thereby, the types of information acquired by the terminal device 40 are increased, whereby the accuracy of grouping the lighting fixtures 12 can be improved, and accordingly, the work time of the mapping can be shortened. In this example, although the accuracy of grouping may be lower than that of the configurations described with reference to
In the above configuration, the case has been described where the measurement unit 18 measures, as the “information”, the combination of the energizing time, the number of power-on times, and the cumulative energizing time of the lighting fixtures 12, but the present invention is not limited thereto, and the above “information” may be the combination of two or more of the energizing time, the non-energizing time, the number of times of zero crossing of the input voltage, and the number of on/off times of the power in the lighting fixture 12.
According to at least one of the above embodiments, the power supply device incorporated in the lighting fixture is disclosed. The power supply device includes a power conversion unit, a control unit, a communication unit, a storage unit, and a measurement unit, measures information in the measurement unit based on a predetermined operation or action, and stores the information measured by the measurement unit in the storage unit when a predetermined detection is made. According to the above power supply device, it is possible to shorten a work time when mapping of the lighting fixtures is performed using the terminal device.
Further, according to at least one of the above embodiments, there is also disclosed the power supply device in which when a series of actions of the power supply and the power supply cutoff to the control unit from outside is performed one or more times by the predetermined operation in the power supply device, the storage unit stores, as information, one or more of the energizing time, the non-energizing time, the number of times of zero crossing of the input voltage, and the number of on/off times of the power in the lighting fixture.
