JP 2013-236361 A

In a wireless lighting control system such as that in Patent Document 1, linking addresses to lighting fixtures can be complicated. Generally, addresses are randomly assigned to the wireless modules installed in lighting fixtures. For this reason, in order to link addresses to multiple lighting fixtures, it is necessary to obtain the wireless addresses of all lighting fixtures, turn on each lighting fixture one by one using the obtained addresses, and visually confirm the installation locations. There may be tens of thousands of lighting fixtures installed in a single property. Therefore, there is a risk that a huge amount of work will be required to link addresses to multiple lighting fixtures.

This disclosure has been made to solve the above-mentioned problems, and aims to provide a lighting device, lighting fixture, and lighting control system that can easily link addresses to lighting fixtures.

The lighting device of the present disclosure includes a power supply unit having a lighting circuit that turns on a light source and a control circuit that controls the lighting circuit in response to a wireless signal, a first communication unit that receives the wireless signal from an external operating device, and a second communication unit that is supplied with power by electromagnetic waves or electromagnetic induction generated between an external device and performs wireless communication with the external device, receives a destination address of the wireless signal stored in the operating device via the wireless communication, and registers it as an identification address of the first communication unit , and the external device transmits the destination address of the wireless signal without knowing the identification information that identifies the first communication unit .

In the lighting device according to the present disclosure, the destination address of the wireless signal stored in the control device can be matched with the identification address of the first communication unit through wireless communication by the second communication unit. This makes it easy to link addresses with lighting fixtures.

Embodiment 1.
Fig. 1 is a perspective view of a lighting fixture 500 according to the first embodiment. The lighting fixture 500 includes a rectangular housing 210 and a light source unit 200 attached to the housing 210. A power supply device 220 (described later) is housed inside the housing. The lighting fixture 500 is attached to a mounting portion such as a ceiling.

A communication circuit unit 520 is attached to the side of the housing 210. A first communication unit 100 and a second communication unit 101 are housed inside the communication circuit unit 520. The second communication unit 101 communicates with an external device 530. The external device 530 is, for example, an information communication terminal such as a smartphone or a tablet. The external device 530 is a general-purpose reader/writer for short-range wireless communication or has a reader/writer function for short-range wireless communication.

In this embodiment, short-range wireless communication is performed between the external device 530 and the second communication unit 101 by holding the external device 530 over the second communication unit 101 from outside the lighting device 500. The short-range wireless communication is an example of a communication method between the external device 530 and the second communication unit 101. The short-range wireless communication between the external device 530 and the second communication unit 101 is performed in a state where the lighting device 500 is installed on the mounting portion.

Figure 2 is a circuit block diagram of a lighting fixture 500 according to embodiment 1. The lighting fixture 500 includes a load circuit section 40 and a lighting device 400.

An external power source AC is connected to the input side of the lighting device 400. The lighting device 400 receives power from the external power source AC and lights up the light sources 41 to 44. The external power source AC is, for example, an AC power source such as a commercial power source. The lighting device 400 may also be connected to a DC power source. In this case, the rectifier circuit and harmonic suppression circuit 20 described below are not required.

The load circuit section 40 is connected to the output side of the lighting device 400. The load circuit section 40 has multiple light sources 41-44. The light sources 41-44 are, for example, light-emitting elements such as LEDs. In the load circuit section 40, the light sources 41-44 form an LED lamp or LED module. The light source section 200 includes the load circuit section 40. In the load circuit section 40, the multiple light sources 41-44 are connected in series. This is not limiting, and the multiple light sources 41-44 may be connected in parallel or in series-parallel. Furthermore, it is sufficient that the load circuit section 40 has one or more light sources 41-44.

In general, the lighting fixture 500 using semiconductor light sources such as light-emitting diodes as the light sources 41 to 44 has higher conversion efficiency and optical efficiency than fluorescent lamps, discharge lamps, or incandescent lamps. Therefore, the energy consumption of the lighting fixture 500 can be reduced. Furthermore, with semiconductor light sources, it is generally easier to adjust the dimming level than with fluorescent lamps, discharge lamps, or incandescent lamps. Therefore, the brightness can be controlled in a finer detail.

The lighting device 400 includes an input filter rectifier circuit 10, a harmonic suppression circuit 20, a current adjustment circuit 30, a control circuit 50, a first communication unit 100, and a second communication unit 101. The harmonic suppression circuit 20 and the current adjustment circuit 30 constitute a lighting circuit 25. The input filter rectifier circuit 10, the harmonic suppression circuit 20, the current adjustment circuit 30, and the control circuit 50 constitute a power supply device 220.

The input filter rectifier circuit 10 includes an input filter circuit 11 connected to an external power source AC, and a rectifier circuit connected to the output side of the input filter circuit 11. The input filter circuit 11 is composed of an inductor and a capacitor (not shown). The input filter circuit 11 removes noise. The rectifier circuit is composed of diodes 12 to 15. The rectifier circuit full-wave rectifies the AC voltage.

The harmonic suppression circuit 20 is a power factor improvement circuit of the boost chopper type. The harmonic suppression circuit 20 is connected to the output of the rectifier circuit. The harmonic suppression circuit 20 boosts the pulsating voltage rectified by the rectifier circuit, and charges the smoothing capacitor 23 with a predetermined high DC voltage. The harmonic suppression circuit 20 performs switching so that the input current becomes a sine wave, and controls the chopper output voltage to a constant value.

The harmonic suppression circuit 20 includes an inductor 21. One end of the inductor 21 is connected to the high potential side of the output of the rectifier circuit. The other end of the inductor 21 is connected to the drain of the switching element 24 and the anode of the diode 22.

The switching element 24 is, for example, a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). The source of the switching element 24 is connected to the negative electrode of the smoothing capacitor 23. The gate of the switching element 24 is connected to the drive circuit 52 of the control circuit 50. The cathode of the diode 22 is connected to the positive electrode of the smoothing capacitor 23. The negative electrode of the smoothing capacitor 23 is connected to the low-potential side of the output of the rectifier circuit.

The control circuit 50 includes a microcomputer 51 and a drive circuit 52. The microcomputer 51 has a processing unit 51a and a memory 51b. The processing unit 51a turns the switching element 24 on and off according to a program stored in the memory 51b.

Here, the output voltage of the microcomputer 51 is generally smaller than the drive voltage of the MOSFET. For this reason, the switching signal from the microcomputer 51 is input to the drive circuit 52. The drive circuit 52 turns the switching element 24 on and off in response to the switching signal. This allows stable switching to be achieved.

The current adjustment circuit 30 is connected to the smoothing capacitor 23. The current adjustment circuit 30 is a circuit that passes a direct current to the load circuit section 40. The current adjustment circuit 30 receives power from the smoothing capacitor 23 and lights up the light sources 41 to 44. The current adjustment circuit 30 is, for example, a buck converter type, and is constant current controlled.

In the current adjustment circuit 30, the drain of the switching element 31 is connected to the positive electrode of the smoothing capacitor 23. The switching element 31 is, for example, a MOSFET. The source of the switching element 31 is connected to the cathode of the diode 34 and one end of the inductor 32. The gate of the switching element 31 is connected to the drive circuit 52.

The anode of the diode 34 is connected to the negative electrode of the smoothing capacitor 23 and one end of the current detection resistor 35. The other end of the inductor 32 is connected to the positive electrode of the capacitor 33. The other end of the current detection resistor 35 is connected to the negative electrode of the capacitor 33. The load circuit section 40 is connected in parallel to the capacitor 33. The output voltage of the current adjustment circuit 30 is smoothed by the capacitor 33 and supplied to the load circuit section 40.

The voltage applied to the current detection resistor 35 corresponds to the current flowing through the load circuit section 40. The current flowing through the LED is converted to a voltage by the current detection resistor 35 and input to the microcomputer 51. The microcomputer 51 detects the voltage applied to the current detection resistor 35.

The memory 51b stores a program that controls the current adjustment circuit 30. The processing device 51a compares the voltage applied to the current detection resistor 35 with a set value in the program, and turns the switching element 31 on and off so that the two match. Thus, in this embodiment, the output current of the lighting circuit 25 is determined by the microcomputer program. As with the switching element 24, the microcomputer 51 turns the switching element 31 on and off via the drive circuit 52. As a result, the light sources 41 to 44 are lit with constant current control.

Next, the control circuit 50 will be described in detail. The control circuit 50 includes a microcomputer 51, a drive circuit 52, and a control power supply circuit 53. The microcomputer 51 is also called a microcomputer. The microcomputer 51 controls the operation of the harmonic suppression circuit 20 and the current adjustment circuit 30 via the drive circuit 52.

The drive circuit 52 drives the switching elements 24 and 31 in synchronization with the pulse signal input from the microcomputer 51. The drive circuit 52 drives the switching elements 24 and 31 independently.

The control power supply circuit 53 generates a constant voltage from the DC voltage rectified by the input filter rectifier circuit 10 using a step-down chopper, dropper, etc. configuration. This constant voltage is supplied to the microcomputer 51, the drive circuit 52, the first communication unit 100, and the second communication unit 101.

Next, the first communication unit 100 will be described. The first communication unit 100 is composed of a wireless module with an individual address. The first communication unit 100 performs communication over a distance of several meters to several hundreds of meters using Bluetooth (registered trademark), Wi-Fi, Sub-GHz wireless, etc. The first communication unit 100 receives wireless signals from an external operation device 800 and transfers them to the microcomputer 51 of the control circuit 50. The operation device 800 is a controller of a wireless control system, etc. The wireless signals include commands such as turning on, turning off, and dimming.

Next, the second communication unit 101 will be described. FIG. 3 is a plan view of the second communication unit 101 according to the first embodiment. The second communication unit 101 includes an antenna 111, a cable 112, and a package 113. The package 113 houses an NFC_IC 110, which will be described later. The second communication unit 101 receives power from the power supply device 220 via the cable 112. The second communication unit 101 also communicates with the control circuit 50 via the cable 112.

The antenna 111, which is a wireless communication element, is used for short-distance wireless communication between the second communication unit 101 and the external device 530. The short-distance wireless communication between the second communication unit 101 and the external device 530 is NFC (Near Field Communication). NFC uses a frequency of, for example, 13.56 MHz. The communication distance is about 10 cm. The short-distance wireless communication process, including encryption processing, is completed within about 0.1 seconds. In this embodiment, communication can be performed contactlessly by bringing the external device 530 close to the second communication unit 101.

The NFC_IC 110 is also known as a dynamic tag, for example. By using a dynamic tag, data received by the antenna 111 can be written to an external microcontroller via I2C (Inter-Integrated Circuit) output.

Figure 4 is a diagram showing the configuration of the second communication unit 101 according to the first embodiment. The second communication unit 101 includes an antenna 111 and an NFC_IC 110. For example, the ST25DV series manufactured by STMicroelectronics (registered trademark) can be used as the NFC_IC 110. The NFC_IC 110 includes a power generation circuit 110a, a digital output circuit 110b, a memory 110c, and a buffer (not shown). The memory 110c is, for example, an EEPROM (Electrically Erasable Programmable Read-Only Memory).

When the external device 530 is held over the second communication unit 101, an induced current is generated between the external device 530 and the second communication unit 101 due to a magnetic field. The second communication unit 101 is supplied with power by electromagnetic waves or electromagnetic induction generated between the external device 530 and the antenna 111, and performs short-range wireless communication with the external device 530. Data transmitted and received by short-range wireless communication is, for example, the destination address of the first communication unit 100. Furthermore, when the second communication unit 101 receives data from the external device 530, it stores the received data in the memory 110c using the power generated by the short-range wireless communication.

The power generation circuit 110a generates power from the power generated by short-range wireless communication to transmit and receive data and write data to the memory 110c.

As described above, the second communication unit 101 receives data using the electromagnetic or radio wave energy used in short-range wireless communication, regardless of whether the power supply device 220 is energized or not, and stores the data in the memory 110c. The second communication unit 101 can receive data from the external device 530 even when no power is being supplied to the power supply device 220. This allows the user to transfer data without considering whether the power supply device 220 is energized or not. This improves the operability of the lighting device 500.

When power is supplied from the external power source AC to the power supply device 220, the control power supply circuit 53 generates a constant voltage. This constant voltage is supplied to the digital output circuit 110b. The microcomputer 51 has a write terminal 51c. The digital output circuit 110b is connected to the write terminal 51c. The digital output circuit 110b outputs data stored in the memory 110c to the microcomputer 51 via the write terminal 51c. In this way, the second communication unit 101 is supplied with power from the power supply device 220 and writes the data stored in the memory 110c to the memory 51b of the control circuit 50. The data is written to the microcomputer 51 by I2C communication. This is not limited to this, and other methods may be used as long as the data is written to the control circuit 50.

As a result, when power is being supplied to the power supply device 220, the second communication unit 101 writes the stored data to the control circuit 50 using the power supplied when the power supply device 220 is energized.

Next, the operation of assigning an identification address to the first communication unit 100 will be described. The identification address is a wireless address assigned to each of the multiple first communication units 100. The identification address is created by a device external to the lighting fixture 500 as a destination address for wireless communication. The external device is a personal computer, a smartphone, etc. The destination address is stored in the operation device 800.

The destination address may be generated by the external device 530 or the communication device 700 described below. The external device 530 or the communication device 700 has a setting screen showing the arrangement of the lighting fixtures 500. The user generates the destination address in advance using the setting screen. The destination address is transmitted to the second communication unit 101 as an identification address. The destination address may be set to a numerical value freely selected by the user in advance. The destination address may also be assigned in an easy-to-understand manner in association with the arrangement of the lighting fixtures 500.

The external device 530 and the communication device 700 may have a function to automatically generate a destination address according to the arrangement of the lighting devices 500. For example, consecutive addresses may be generated as destination addresses according to the arrangement order of the lighting devices 500. The external device 530 and the communication device 700 also have a function to transmit the destination address of the wireless signal to the control device 800. In other words, the external device 530 and the communication device 700 have a function to store the destination address in the control device 800.

The user brings the external device 530 close to the communication circuit unit 520 of the lighting device 500. As a result, the second communication unit 101 receives the destination address from the external device 530 by short-range wireless communication. The second communication unit 101 stores the received destination address in the memory 110c as the identification address of the first communication unit 100. At this time, the second communication unit 101 may receive the destination address from the external device 530 in a state where power is not being supplied to the power supply device 220.

The second communication unit 101 receives a destination address from the external device 530, stores it as an identification address, and then receives power from the power supply device 220 and writes the identification address to the memory 51b of the control circuit 50. Therefore, any identification address can be assigned to the first communication unit 100. As a result, the destination address of the wireless signal stored in the operation device 800 matches the identification address of the first communication unit 100.

The operating device 800 transmits a wireless signal to the stored destination address. When the first communication unit 100 receives a wireless signal addressed to the identification address of the first communication unit 100, it transmits the wireless signal to the control circuit 50. The control circuit 50 controls the lighting circuit 25 in response to the wireless signal. This controls the lighting state of the light source unit 200 in response to the wireless signal.

Generally, connecting a continuous dimming type lighting fixture to a lighting control system allows for fine control of brightness. However, a dimming method using wired communication requires wiring to each fixture that makes up the lighting control system. This can result in high installation costs. In contrast, in this embodiment, the lighting state of the light source unit 200 is controlled by a wireless signal. This allows for easy installation and reduces installation costs.

In this embodiment, the operation device 800 of the wireless control system may control the brightness of the light source unit 200 by wireless signals according to the illuminance value detected by the illuminance sensor. This enables dimming using external light. The operation device 800 may also turn off the lighting device 500 by wireless signals when the user is not present according to information detected by the human presence sensor. This type of control can reduce the power consumption of the lighting device 500.

In addition, in a wireless control system, the linking of addresses and lighting fixtures can generally be complicated. As a method of linking addresses and lighting fixtures, for example, the wireless address of the lighting fixture is acquired by communication, and the lighting fixture is turned on with the acquired address to visually confirm the installation location. In contrast, in the present embodiment, the external device 530 is held over the second communication unit 101 at the installation location of the lighting fixture, and the destination address is transmitted from the external device 530 to the second communication unit 101. Therefore, the position of the lighting fixture 500 can be grasped and an identification address can be assigned at the same time. Therefore, the destination address can be easily linked to the lighting fixture 500. Also, an arbitrary address can be easily assigned to the first communication unit 100 by holding the external device 530 over the second communication unit 101.

A lighting control system may also be configured with multiple lighting fixtures 500. In this case, a destination address may be created for each of the multiple lighting fixtures 500 and assigned as an identification address. Additionally, multiple destination addresses created by the user are registered in the operation device 800 that transmits wireless signals to the first communication unit 100. This allows the operation device 800 to control the multiple lighting fixtures 500 individually. Additionally, the task of linking the destination addresses with the multiple lighting fixtures 500 can be simplified.

In addition, by using short-range wireless communication, an identification address can be assigned only to the lighting fixture 500 that the external device 530 is in close proximity to. Since short-range wireless communication allows communication only with specific lighting fixtures 500, it is possible to prevent an identification address from being assigned to an unintended fixture.

In this embodiment, the second communication unit 101 receives a destination address as the identification address of the first communication unit 100 from the external device 530 via short-range wireless communication. As a variation of this embodiment, the second communication unit 101 may transmit the randomly assigned identification address of the first communication unit 100 as the destination address of a wireless signal to the external device 530 via short-range wireless communication.

In a modified example, the control circuit 50 writes the identification address stored in the memory 51b to the memory 110c of the second communication unit 101. The identification address is transmitted from the second communication unit 101 to the external device 530 as a destination address by holding the external device 530 over the second communication unit 101. The identification address is read by the external device 530 using the energy of electromagnetic waves or radio waves used in short-range wireless communication, regardless of whether the power supply device 220 is energized or not. The identification address received by the external device 530 is registered in the operation device 800 as a destination address. In this case, too, the destination address of the wireless signal stored in the operation device 800 can be made to match the identification address of the first communication unit 100. Therefore, the destination address can be easily linked to the lighting device 500.

As shown in FIG. 1, the second communication unit 101 is housed in a housing for safety reasons. This makes it possible to protect the user from electric shock. On the other hand, in short-range wireless communication, if the transmitter and receiver are separated by metal, communication generally becomes difficult. For this reason, it is preferable that the housing housing the second communication unit 101 is made of resin or a non-metal. Also, of the housing housing the communication circuit unit 520, only the portion covering the second communication unit 101 or the portion adjacent to the second communication unit 101 may be made of resin or a non-metal.

When short-range wireless communication is being carried out between the external device 530 and the second communication unit 101, the second communication unit 101 and the external device 530 are separated by a non-metallic member. This allows for stable short-range wireless communication. In addition, the destination address can be sent and received even when the lighting device 500 is installed at the place of use or when the lighting device 500 is assembled. This improves the operability of the lighting device 500 and makes it easy to assign an identification address.

Similarly, the housing that houses the first communication unit 100 may be made partially or entirely of resin or non-metal.

The short-distance wireless communication between the second communication unit 101 and the external device 530 may be RFID (Radio Frequency Identifier). It is preferable that the wireless communication method between the second communication unit 101 and the external device 530 is a short-distance wireless method with a communication distance of, for example, about 1 cm to 1 m.

These modifications can be applied as appropriate to the lighting devices, lighting fixtures, and lighting control systems according to the following embodiments. Note that the lighting devices, lighting fixtures, and lighting control systems according to the following embodiments have many things in common with embodiment 1, so the following description will focus on the differences from embodiment 1.

Embodiment 2.
Fig. 5 is a diagram illustrating a lighting control system 600 according to the second embodiment. The lighting control system 600 includes a plurality of lighting fixtures 500. Fig. 5 shows a state in which a plurality of lighting fixtures 500 are installed on a ceiling. The plurality of lighting fixtures 500 are divided into a plurality of control groups. The plurality of control groups are, for example, groups A to C. A plurality of lighting fixtures 500a belong to group A. A plurality of lighting fixtures 500b belong to group B. A plurality of lighting fixtures 500c belong to group C.

External devices 530a, 530b, 530c control groups A to C, respectively. External device 530a transmits group information to multiple lighting fixtures 500a that are set in group A among the multiple lighting fixtures 500 via short-range wireless communication. The group information is information about the group to which the lighting fixtures 500 belong. The user assigns group information to each of the multiple lighting fixtures 500a that are set in group A by bringing external device 530a close to each of the multiple lighting fixtures 500a. The group information is assigned when the lighting fixtures 500 are installed on the ceiling.

In each of the lighting fixtures 500a, the second communication unit 101 receives information about the group to which it belongs from the external device 530. As a result, the control circuit 50 of the lighting fixture 500a controls the lighting circuit 25 in response to the wireless signal addressed to group A to which the lighting fixture 500a belongs. Similarly, groups B and C are given group information from external devices 530b and 530c, respectively.

According to this embodiment, control groups can be easily set for multiple lighting fixtures 500. This allows for centralized control for each control group.

As a variation of this embodiment, instead of group information, the same identification address may be assigned to multiple lighting fixtures 500 that belong to the same control group. In this case, it is also possible to perform centralized control for each control group.

Embodiment 3.
Fig. 6 is a diagram illustrating a lighting control system 600a according to embodiment 3. Fig. 7 is a diagram illustrating a configuration of a communication device 700 according to embodiment 3. Lighting control system 600a includes a plurality of lighting fixtures 500 and a plurality of communication devices 700. The plurality of communication devices 700 include communication devices 700a and 700b.

The communication device 700 is, for example, an operation remote control. The communication device 700 has a third communication unit 701 and a fourth communication unit 702. The third communication unit 701 transmits a wireless signal to the first communication unit 100. The third communication unit 701 is composed of a wireless module capable of communication over a distance of several meters to several hundreds of meters, such as Bluetooth (registered trademark), Wi-Fi, or Sub-GHz wireless. The third communication unit 701 transmits a wireless signal to the first communication unit 100 using the same communication protocol as the operation device 800 of the wireless control system. The fourth communication unit 702 performs short-range wireless communication with the second communication unit 101. The fourth communication unit 702 is composed of a short-range wireless element such as NFC or RFID.

Note that a communication device 700 may be provided separately from the operation device 800 of the wireless control system. Alternatively, the communication device 700 may be provided instead of the operation device 800. In other words, the lighting control system 600a does not need to communicate with the wireless control system.

When the communication device 700 is brought close to the communication circuit unit 520 of the lighting fixture 500, the second communication unit 101 transmits the identification address of the first communication unit 100 to the fourth communication unit 702 of the communication device 700 by short-range wireless communication. The fourth communication unit 702 receives the identification address from the second communication unit 101 and stores it in the memory of the communication device 700 as a destination address.

The third communication unit 701 transmits a wireless signal to the stored destination address. This allows the communication device 700 to control the lighting fixture 500 whose identification address has been received by the fourth communication unit 702.

For example, the user brings the communication device 700a close to the communication circuit unit 520 of each of the multiple lighting fixtures 500a belonging to group A in FIG. 6. This allows the communication device 700a to acquire the identification address of each of the multiple lighting fixtures 500a and store it as a destination address. The communication device 700a transmits a wireless signal from the third communication unit 701 only to the lighting fixtures 500a among the multiple lighting fixtures 500 whose destination addresses have been stored. The lighting fixtures 500a among the multiple lighting fixtures 500 that correspond to the destination address of the wireless signal receive the wireless signal via the first communication unit 100 and control the lighting state of the light source unit 200 in response to the wireless signal.

Similarly, the user brings the communication device 700b close to the communication circuit unit 520 of each of the multiple lighting fixtures 500b belonging to group B. This allows the communication device 700b to obtain the identification address of each of the multiple lighting fixtures 500b. The communication device 700b transmits a wireless signal to the lighting fixture 500b. As a result, the lighting fixture 500b among the multiple lighting fixtures 500 controls the lighting state of the light source unit 200 in response to the wireless signal.

In this embodiment, the fourth communication unit 702 of the communication device 700 receives multiple identification addresses from the second communication unit 101 of the multiple lighting fixtures 500, respectively. The third communication unit 701 of the communication device 700 collectively controls the multiple lighting fixtures 500 using the multiple identification addresses. In this way, by acquiring the identification addresses and transmitting wireless signals using a single communication device 700, it is possible to more easily link the destination addresses with the lighting fixtures 500.

In addition, in this embodiment, the multiple lighting fixtures 500 include multiple lighting fixtures 500a belonging to group A and multiple lighting fixtures 500b belonging to group B. The communication device 700a receives multiple first identification addresses from the multiple lighting fixtures 500a, respectively, and controls the multiple lighting fixtures 500a collectively using the multiple first identification addresses. Similarly, the communication device 700b receives multiple second identification addresses from the multiple lighting fixtures 500b, respectively, and controls the multiple lighting fixtures 500b collectively using the multiple second identification addresses.

In other words, in this embodiment, a dedicated communication device 700 is provided for each control group. By independently operating each of the multiple control groups using the multiple communication devices 700, group control can be easily performed. Also, in this embodiment, only the lighting fixtures 500 that are placed close to the communication device 700 can be individually remote-controlled. Therefore, group control of multiple lighting fixtures 500 can be easily performed.

In addition, three or more communication devices 700 may be used to independently control three or more control groups. Also, one communication device 700 may control multiple control groups. In this case, the control group to be controlled is switched by operating a switch provided on the communication device 700, for example.

In addition, although an example of group control has been shown in this embodiment, a single lighting fixture 500 may also be controlled by the communication device 700.

In the present embodiment, the identification address preset in the first communication unit 100 is read by the communication device 700 and stored in the memory of the communication device 700 as a destination address. As a variation of this, the fourth communication unit 702 of the communication device 700 may transmit the destination address to the second communication unit 101. In this case, the destination address of the wireless signal that serves as the identification address is created, for example, by the user. The destination address is registered in the communication device 700. The fourth communication unit 702 of the communication device 700 transmits the destination address to the second communication unit 101 by short-range wireless communication. The second communication unit 101 stores the destination address as an identification address and writes it to the control circuit 50. As a result, the identification address is assigned to the first communication unit 100.

In a modified example, the third communication unit 701 of the communication device 700 controls the lighting device 500 by transmitting a wireless signal to the destination address. In this case, too, the assignment of the identification address and the transmission of the wireless signal are performed by a single communication device 700, so that the destination address can be easily linked to the lighting device 500.

Embodiment 4.
6 may be controlled by a communication device 700 and an operation device 800 of a wireless control system. The communication device 700 and the wireless control system transmit wireless signals to the first communication unit 100 using the same communication protocol.

The first communication unit 100 receives wireless signals from the communication device 700 and the operation device 800 of the wireless control system. The control circuit 50 controls the lighting circuit 25 by prioritizing the wireless signal from the communication device 700 over the wireless signal from the operation device 800.

In other words, among the multiple lighting fixtures 500, only the lighting fixtures 500 that have transmitted or received a destination address to or from the communication device 700 are controlled by the communication device 700. The lighting fixtures 500 that are not communicating with the communication device 700 are controlled by the wireless control system.

In this embodiment, in a lighting space controlled by a wireless control system, only some of the lighting fixtures 500 can be controlled by the communication device 700. This makes it possible, for example, to turn off only the lighting fixtures 500 in areas where no users are present. Also, it is possible to brighten only a portion of the lighting space. This improves the convenience of the lighting control system 600a.

In addition, in this embodiment, the wireless control system and the communication device 700 control the lighting fixtures 500 using the same communication protocol. Therefore, when constructing a lighting control system 600a using the communication device 700, a wireless unit for the wireless control system can be used as the first communication unit 100. In this case, there is no need to add special control, and the lighting control system 600a can be constructed at low cost and in a short period of time.

The technical features described in each embodiment may be used in any suitable combination.
