FIG. 1 is a diagram showing a lighting system 10 including a lighting equipment remote control 30 according to an example embodiment. The lighting system 10 includes a lighting fixture remote controller 30 and lighting fixtures set or controlled by the lighting fixture remote controller 30. The lighting fixtures are a plurality of first lighting fixtures 12 and a plurality of second lighting fixtures 14, which are usually placed inside a building. The plurality of second lighting fixtures 14 are installed at positions farther away from one first lighting fixture 12 of the plurality of first lighting fixtures 12 than the maximum interval between two first lighting fixtures 12. For example, each of the plurality of second lighting fixtures 14 is installed at a position farther away from the second lighting fixture 14 at one end than the maximum distance between the two first lighting fixtures 12 at both ends. The plurality of second lighting fixtures 14 are installed, for example, outdoors of a building. The plurality of second lighting fixtures 14 may be placed indoors. For example, even if an attempt is made to operate the second lighting fixtures 14 indoors using the lighting remote controller 30 from a position where the first lighting fixture 12 can be operated using the lighting equipment remote controller 30, the control signal is not received. The second lighting fixture 14 cannot be reached normally and, for example, the lighting fixture remote control 30 is in a position where a warning such as an error display is generated. Below, a case where a plurality of second lighting fixtures 14 are installed outdoors will be described. The lighting fixture remote control 30 is configured to be able to communicate wirelessly with each first lighting fixture 12 and each second lighting fixture 14, and sets or controls each first lighting fixture 12 and each second lighting fixture 14. More specifically, regarding the second lighting fixtures 14, each second lighting fixture 14 is capable of wireless communication with at least a nearby lighting fixture remote control 30. Hereinafter, the lighting equipment remote control 30 will be referred to as a remote control 30. As will be described in detail later, the remote controller 30 sets the setting information in the second lighting fixture 14 by transmitting the setting information set by the user 1's operation to the second lighting fixture 14, or sets the setting information in the second lighting fixture 14, or The first lighting fixture 12 is controlled according to the content of the setting information set by the operation.

The number of first lighting fixtures 12 included in the lighting system 10 is not particularly limited as long as it is plural. The number of second lighting fixtures 14 included in the lighting system 10 is not particularly limited as long as it is one or more. The plurality of first lighting fixtures 12 are, for example, ceiling lights. The first lighting fixture 12 may be of other types, such as a downlight or a spotlight. In FIG. 1, the first lighting fixture 12 is indicated by a circle. The plurality of second lighting fixtures 14 are, for example, spotlights. The second lighting fixture 14 may be of other types, such as a garden light.

The plurality of first lighting fixtures 12 are divided into four groups, group 1, group 2, group 3, and group 4, and each group has a plurality of first lighting fixtures 12. In each group, a plurality of first lighting fixtures 12 can communicate wirelessly with each other.

FIG. 2 is a diagram showing the configuration of the first lighting fixture 12 and the remote control 30 that constitute the lighting system 10. The first lighting fixture 12 is connected to a remote control 30 operated by the user 1 so as to be able to communicate wirelessly. When operated by the user 1, the remote control 30 transmits a lighting control signal according to the operation or setting information set by the operation. In FIG. 2, only two first lighting fixtures 12 are shown as the plurality of first lighting fixtures 12. The first lighting fixture 12 includes a communication section 16, a control circuit 18, a light source section 20, and a storage section 22. When the first lighting fixture 12 first receives a lighting control signal within the same group from the remote controller 30, it transfers the lighting control signal to other first lighting fixtures 12 in the same group. Although the configurations of the plurality of first lighting fixtures 12 may be the same, the plurality of first lighting fixtures 12 may have different configurations. The first lighting fixture 12 that receives the lighting control signal from the remote controller 30 first in the same group transmits a reception confirmation signal as a reply signal to the remote controller 30.

The communication unit 16 is an interface for the first lighting fixture 12 to wirelessly communicate with the remote control 30 and other first lighting fixtures 12 in the same group.

Control circuit 18 controls communication section 16 . The control circuit 18 controls the lighting state of the light source section 20 according to a lighting control signal received from the remote controller 30. The control circuit 18 includes, for example, a CPU, and arithmetic processing is executed by a program stored in the storage unit 22. When the control circuit 18 first receives a lighting control signal from the remote controller 30 in the same group, it transfers the lighting control signal to the other first lighting fixtures 12 in the same group. Further, when the control circuit 18 first receives a lighting control signal from the remote controller 30 in the same group, it transmits a reception confirmation signal to the remote controller 30. For example, when the control circuit 18 receives a lighting control signal from the remote controller 30 and has not yet received a lighting control signal from another first lighting fixture 12, the control circuit 18 determines that the controller 18 is the first one in the same group from the remote controller 30. It is determined that this is the first lighting fixture that received the lighting control signal, and transmits a reception confirmation signal to the remote controller 30.

The light source section 20 emits illumination light. For example, the light source section 20 is an LED, a fluorescent lamp, a halogen lamp, or the like.

The storage unit 22 is realized by ROM, RAM, HDD, flash memory, etc. The storage unit 22 has a function of storing the received lighting control signal.

The remote control 30 includes an operation section 31, a communication section 32, a control circuit 33, a storage section 34, and a timer section 35. The operation unit 31 receives an operation from the user 1 and transmits the content of the received operation to the control circuit 33. When the remote control 30 is a smartphone, the remote control 30 has a touch panel screen that functions as an operation section.

The communication unit 32 is an interface for the remote control 30 to wirelessly communicate with the plurality of lighting fixtures 12.

The control circuit 33 has a function of controlling the communication section 32. The control circuit 33 has, for example, a CPU, and arithmetic processing is executed by a program stored in a storage unit 34, which will be described later.

When the operation section 31 is operated and the operation is an instruction to control the lighting state of the first lighting fixture 12, the control circuit 33 transmits a lighting control signal to the first lighting device of each group via the communication section 32 as a wireless signal. It is transmitted to the lighting fixture 12. The first lighting fixture 12 in each group that first receives the lighting control signal from the remote controller 30 transfers the lighting control signal to the other first lighting fixtures 12 in the same group. The first lighting fixture 12 that has received the lighting control signal from the remote controller 30 or another first lighting fixture 12 controls the lighting of the light source section 20 according to the content of the lighting control signal. Thereby, the user 1 holding the remote control 30 can operate the lighting state of each first lighting fixture 12 of a plurality of groups.

Furthermore, the control circuit 33 has (1) a function of sending a lighting control signal to the lighting equipment during lighting control according to the content of setting information related to the timer unit 35 described later, and (2) all data of the setting information. It has two functions, one for sending the light to the lighting equipment, and is configured so that it can select which of the functions (1) and (2) to perform depending on the situation.

For example, when controlling the first lighting fixture 12 according to the contents of the setting information, the control circuit 33 executes the function (1), and the second lighting fixture 14 (FIG. 1) is controlled according to the contents of the setting information. When controlling accordingly, the control circuit 33 is caused to perform the function (2). For this reason, the operation unit 31 of the first lighting fixture 12 may be provided with a switching unit such as a button or a switch for switching between operation of the first lighting fixture 12 and operation of the second lighting fixture 14. Furthermore, when the remote control 30 transmits a signal to the plurality of first lighting fixtures 12, many of the first lighting fixtures 12 transmit reception confirmation signals to the remote control 30, and the signal is transmitted from the remote control 30 to the second lighting fixture 14. When the signal is transmitted, a reception confirmation signal is transmitted to the remote controller 30 from a small number of second lighting fixtures 14. For this reason, a configuration is adopted in which the control circuit 33 switches between having the control circuit 33 execute the function (1) or the function (2) depending on the number of reception confirmation signals received by the remote control 30. Good too.

The control circuit 33 executes the function (1) when the operation unit 31 is operated and the operation is an instruction to control the first lighting fixture 12 according to the content of the setting information. At this time, the control circuit 33 stores the setting information in the storage unit 34 and controls the first lighting fixtures 12 of each group according to the content of the setting information.

The setting information includes timer-related information and data for setting or controlling the first lighting fixture 12 or the second lighting fixture 14. The timer related information includes one or more of the current time, timer setting time, lighting state during timer operation, repetition information, and day of the week information. The timer setting time represents the time when lighting control is started or ended. These setting information data have a large amount of data. Therefore, unlike the embodiment, all data of setting information is sent from the remote control to each first lighting fixture, and each first lighting fixture is turned on according to the content of the setting information, for example, when the timer setting time is reached. In the control configuration, the amount of data transmitted from the remote control to each first lighting fixture increases. In this case, if there are return signals from many primary lighting fixtures to the remote controller, communication errors are likely to occur when transmitting signals from the remote controller to each primary lighting fixture, and By not being able to operate the fixture, the operability of the first lighting fixture may be reduced. In the embodiment, the remote controller 30 has a control circuit 33 that controls the first lighting fixture 12 according to the contents of the setting information, and the control circuit 33 controls the lighting during the lighting control according to the contents of the setting information (1). It has the function of sending signals. Furthermore, lighting of the first lighting fixture 12 is controlled in response to reception of a lighting control signal. As a result, communication errors in transmission from the remote control 30 are less likely to occur, so the operability of the first lighting fixture 12 can be improved when there are return signals from many first lighting fixtures 12 to the remote control 30. Further, a setting (configuration) may be adopted in which the lighting control signal does not require a reply. In this case, communication performance is further improved and operability is also enhanced.

Specifically, the remote control 30 includes the storage section 34 and the timer section 35 as described above. The storage unit 34 is realized by ROM, RAM, HDD, flash memory, etc. The storage unit 34 has a function of storing instructions for lighting control by operating the operation unit 31. Further, the storage unit 34 stores setting information when the setting information is set by operating the operation unit 31. Furthermore, the storage unit 34 stores programs. The control circuit 33 can control the first lighting fixture 12 according to the content of the setting information by executing a program stored in the storage unit 34. Further, the remote controller 30 has a battery as a power source, so that the setting information stored in the storage unit 34 is not erased even when the remote controller 30 is powered off.

The timer section 35 measures time. The control circuit 33 calculates the difference between the start time of the lighting control at the timer setting time and the current time as the set time, causes the timer section 35 to measure the time, and when the timer section 35 measures the set time, the control circuit 33 calculates the difference between the start time of the lighting control at the timer setting time and the current time, and causes the timer section 35 to time the set time. Send lighting control signal. The control circuit 33 uses the day of the week information to determine whether the current day of the week is the day of the week to start lighting control, and if the determination is affirmative, the lighting control signal is transmitted at the start time of lighting control. You may also do so. Furthermore, when the control circuit 33 transmits the lighting control signal, lighting may be controlled using the lighting state and repetition information during timer operation.

The remote control 30 and the first lighting fixture 12 are communicably connected, for example, by BLE (Bluetooth (registered trademark) Low Energy) wireless communication. The plurality of first lighting fixtures 12 are also communicably connected to each other by wireless communication such as BLE. For example, the first lighting fixture 12 that receives the lighting control signal from the remote controller 30 transmits the lighting control signal using BLE. Appliance IDs are set for the plurality of first lighting fixtures 12, and by transmitting a signal including the destination's appliance ID, the first lighting fixture 12 at the destination can confirm that the received signal has its own ID. If so, the signal is read and the lighting state of the first lighting fixture 12 is controlled.

Since the remote control 30 transmits the lighting control signal to each group by measuring the set time of the timer section 35 as described above, it is possible to check the on/off state of the timer section 35 using the remote control 30.

FIG. 3 is a diagram showing a state in which a plurality of first lighting fixtures 12 are controlled by the remote controller 30 according to an example of the embodiment. In FIG. 3, the numbers ID: 1 to 4 assigned to each first lighting fixture 12 in group 1 indicate the respective fixture ID, and a lighting control signal is sent from the remote control 30 to the first lighting fixture 12 with ID 4. Shows when to send. The first lighting fixture 12 with ID 4 is the first lighting fixture to which the remote control 30 first received the reception confirmation signal when the lighting control signal was transmitted from the remote control 30 to group 1. In FIG. 3, a white arrow with a circle 1 indicates that a lighting control signal is transmitted from the remote control 30 to the first lighting fixture 12 with ID 4. When the first lighting fixture 12 with ID 4 receives the lighting control signal from the remote controller 30, it sends a reception confirmation signal to the remote controller 30 indicating that the signal has been received, as shown by the dashed-dotted arrow with a circle 2. Send. The reception confirmation signal includes identification information of the first lighting fixture 12 transmitting the signal. Then, as shown by a thin solid arrow with a circle 3, the first lighting fixture 12 with ID 4 transmits a lighting control signal to other first lighting fixtures 12 in group 1 with ID other than 4. Thereby, each first lighting fixture 12 that has received the lighting control signal is controlled to be lit. In FIG. 3, the case of group 1 has been described, but the same applies to groups 2 to 4 in FIG. Therefore, by transmitting a lighting control signal between the remote controller 30 and the first lighting fixtures 12 of the same number as the number of groups, the lighting of all the first lighting fixtures 12 can be controlled. Further, since reception confirmation signals are transmitted to the remote controller 30 only from the same number of first lighting fixtures 12 as the number of groups, this also makes it possible to improve the operability of the first lighting fixtures 12.

Note that the remote control 30 and the first lighting fixture 12 and the plurality of lighting fixtures 12 may be communicably connected by other wireless communication such as Wi-Fi (registered trademark) or Bluetooth (registered trademark). good.

The second lighting fixture 14 includes a communication section 17, a control circuit 19, a light source section 21, a storage section 23, and a timer section 25. Setting information is set in the second lighting fixture 14 when the setting information is transmitted from the remote controller 30. Although the configurations of the plurality of second lighting fixtures 14 may be the same, the plurality of second lighting fixtures 14 may have different configurations.

The communication unit 17 is an interface for the second lighting fixture 14 to wirelessly communicate with the remote control 30.

Control circuit 19 controls communication section 17 . The control circuit 19 controls the lighting state of the light source section 21 according to the lighting control signal received from the remote controller 30. The control circuit 19 includes, for example, a CPU, and arithmetic processing is executed by a program stored in the storage unit 23.

The light source section 21 emits illumination light. For example, the light source section 21 is an LED, a fluorescent lamp, a halogen lamp, or the like.

The storage unit 23 is realized by ROM, RAM, HDD, flash memory, etc. The storage unit 23 has a function of storing the received lighting control signal or the contents of the setting information.

The timer unit 25 measures time. The control circuit 19 calculates the difference between the start time of the lighting control at the timer setting time and the current time as a set time, causes the timer section 25 to measure the time, and when the timer section 25 measures the set time, the light source section 21 Start lighting control using . The control circuit 19 may use the day of the week information to determine whether the current day of the week is the day of the week to start the lighting control, and if the determination is affirmative, the control circuit 19 may start the lighting control at the start time of the lighting control. . Furthermore, when the control circuit 19 starts the lighting control, the lighting may be controlled using the lighting state and repetition information during timer operation.

The remote control 30 and the second lighting fixture 14 are communicably connected by wireless communication such as BLE (Bluetooth (registered trademark) Low Energy), Wi-Fi (registered trademark), Bluetooth (registered trademark), or the like.

When the user 1 sets setting information to each second lighting fixture 14, the user 1 moves near each second lighting fixture 14 and uses the remote control, as shown by the two-dot chain line user 1 in FIG. 30, all of the setting information data is sent from the remote controller 30 to each second lighting fixture 14.
