DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. However, the present invention is not limited to the following embodiment. Note that, in the drawings, the same or equivalent parts are given the same reference symbols and the description will not be repeated.

[0017] First, a lighting system 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing the lighting system 100 according to this embodiment. As shown in Fig. 1, the lighting system 100 includes a plurality of lighting fixtures 1, a bridge 4, a router 5, and a remote control device 6. The lighting system 100 is used, for example, in a house in which a plurality of lighting fixtures 1 are installed. The lighting fixtures 1 are, for example, ceiling-mounted lights such as ceiling lights, or recessed lights such as downlights.

[0018] In this embodiment, the lighting system 100 includes three lighting fixtures 1. Specifically, the lighting system 100 includes a first lighting fixture 1A, a second lighting fixture 1B, and a third lighting fixture 1C.

[0019] The first lighting fixture 1A, the second lighting fixture 1B, and the third lighting fixture 1C are of different types. Specifically, the first lighting fixture 1A is an ON-OFF type lighting fixture. Therefore, the first lighting fixture 1A can only be switched on and off. The second lighting fixture 1B is a dimming type lighting fixture. Therefore, the second lighting fixture 1B can be switched on and off and can also be dimmed. The third lighting fixture 1C is a dimming and color-adjusting type lighting fixture. Therefore, the third lighting fixture 1C can be switched on and off, can be dimmed, and can also be color-adjusted.

[0020] The bridge 4 relays data between each of the first lighting fixture 1A, the second lighting fixture 1B, and the third lighting fixture 1C and the router 5. Specifically, the bridge 4 performs wireless communication between each of the first lighting fixture 1A, the second lighting fixture 1B, and the third lighting fixture 1C. The bridge 4 is also connected to the router 5 via a cable and communicates with the router 5 via the cable. Note that FIG. 1 illustrates a state in which the bridge 4 and the second lighting fixture 1B are communicating with each other.

[0021] Specifically, bridge 4 performs wireless communication conforming to a first communication standard with each of first lighting fixture 1A, second lighting fixture 1B, and third lighting fixture 1C. The first communication standard may be, for example, a serial communication standard. Specifically, the first communication standard may be a short-range wireless standard such as ZIGBEE (registered trademark). The first communication standard is an example of a predetermined communication standard.

[0022] The bridge 4 communicates with the router 5 in accordance with a second communication standard different from the first communication standard. The second communication standard may be, for example, a serial communication standard. Specifically, the second communication standard may be Ethernet (registered trademark).

[0023] The bridge 4 converts a signal (conforming to the first communication standard) received from the first lighting fixture 1A, the second lighting fixture 1B, or the third lighting fixture 1C into a signal conforming to the second communication standard in accordance with a predetermined first rule, and transmits the signal to the router 5. The bridge 4 also converts a signal (conforming to the second communication standard) received from the router 5 into a signal conforming to the first communication standard in accordance with a predetermined second rule, and transmits the signal to the first lighting fixture 1A, the second lighting fixture 1B, or the third lighting fixture 1C. The bridge 4 is an example of a "repeater" and a "first repeater".

[0024] The router 5 relays data between the bridge 4 and the remote control device 6. Specifically, the router 5 performs wireless communication with the remote control device 6 in accordance with a third communication standard different from the first communication standard and the second communication standard. The third communication standard is, for example, a wireless LAN (Local Area Network) standard such as Wi-Fi (registered trademark).

[0025] In detail, the router 5 converts the signal received from the bridge 4 (a signal conforming to the second communication standard) into a signal conforming to the third communication standard in accordance with a predetermined third rule, and transmits it to the remote control device 6. The router 5 also converts the signal received from the remote control device 6 (a signal conforming to the third communication standard) into a signal conforming to the second communication standard in accordance with a predetermined fourth rule, and transmits it to the bridge 4. The router 5 is an example of a "second repeater."

[0026] Remote control device 6 is operated by a user to control first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C. Specifically, remote control device 6 transmits a command to control first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C to first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C via router 5 and bridge 4. Remote control device 6 is, for example, a mobile terminal such as a smartphone.

[0027] More specifically, a user can operate the remote control device 6 to control turning on and off the first lighting fixture 1A. The user can also operate the remote control device 6 to control turning on, off, and dimming the second lighting fixture 1B. The user can also operate the remote control device 6 to control turning on, off, dimming, and adjusting the color of the third lighting fixture 1C. When operated by the user, the remote control device 6 transmits a signal corresponding to the user's operation to the router 5.

[0028] The signal transmitted from the remote control device 6 to the router 5 is a signal compliant with the third communication standard. Furthermore, the signal transmitted from the remote control device 6 to the router 5 includes command information. The command information indicates a command for the lighting fixture 1 to be controlled. The signal transmitted from the remote control device 6 to the router 5 further includes type information 151 and identification information 152, which will be described with reference to FIG. 3.

[0029] The lighting fixture 1 to be controlled is any one of a first lighting fixture 1A, a second lighting fixture 1B, and a third lighting fixture 1C. Type information 151 indicates the type of the lighting fixture 1 to be controlled. Identification information 152 is information for identifying the lighting fixture 1 to be controlled. Each of the multiple lighting fixtures 1 is assigned different identification information 152. The identification information 152 is, for example, an address.

[0030] The command is, for example, a turn-on command, a turn-off command, a dimming command, or a color adjustment command. The turn-on command is a command to turn on the lighting fixture 1 to be controlled. The turn-off command is a command to turn off the lighting fixture 1 to be controlled. The dimming command is a command to dim the lighting fixture 1 to be controlled. Specifically, the dimming command is a command to change the amount of light emitted from the lighting fixture 1 to a specified amount of light. The dimming command includes light amount information indicating the specified amount of light. The color adjustment command is a command to adjust the color of the lighting fixture 1 to be controlled. Specifically, the color adjustment command is a command to change the color of the light emitted from the lighting fixture 1 to a specified light color. The color adjustment command includes light color information indicating the specified light color.

[0031] Router 5 converts the signal received from remote control device 6 (signal conforming to the third communication standard) into a signal conforming to the second communication standard and transmits it to bridge 4. Bridge 4 converts the signal received from router 5 (signal conforming to the second communication standard) into a signal conforming to the first communication standard and transmits it to first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C.

[0032] In detail, the bridge 4 determines a destination lighting fixture 1 based on identification information 152 included in a signal received from the router 5. More specifically, the bridge 4 broadcasts a signal indicating the identification information 152. Then, the bridge 4 determines a destination lighting fixture 1 based on a reply signal from the first lighting fixture 1A, the second lighting fixture 1B, or the third lighting fixture 1C. The bridge 4 transmits a signal including command information, type information 151, and identification information 152 to the determined lighting fixture 1. As a result, the lighting fixture 1 to be controlled is controlled in response to a user operation. Note that in the following description, the signal including the command information, type information 151, and identification information 152 may be referred to as a "command signal."

[0033] Next, the first lighting device 1A will be described with reference to Fig. 2. Fig. 2 is a diagram showing the configuration of the first lighting device 1A according to the present embodiment. As shown in Fig. 2, the first lighting device 1A includes a first input terminal 11a, a second input terminal 11b, a rectifier circuit 110, a smoothing circuit 120, a constant current circuit 130, a first lighting control unit 140A, a first storage unit 150A, a switch unit 160, a light source unit 200, and a wireless communication unit 300.

[0034] The first input terminal 11a and the second input terminal 11b are electrically connected to an external AC power source A. The rectifier circuit 110 is electrically connected to the AC power source A via the first input terminal 11a and the second input terminal 11b. The rectifier circuit 110 rectifies the AC voltage supplied from the AC power source A. The rectified AC voltage is input to the smoothing circuit 120 and the first lighting control unit 140A. In this embodiment, the rectifier circuit 110 has a full-wave rectifier circuit 111. Note that the rectifier circuit 110 is not limited to the full-wave rectifier circuit 111. The rectifier circuit 110 may be a half-wave rectifier circuit.

[0035] The smoothing circuit 120 smoothes the rectified AC voltage. Thus, the rectifier circuit 110 and the smoothing circuit 120 convert the AC voltage supplied from the AC power source A into a DC voltage. In other words, the rectifier circuit 110 and the smoothing circuit 120 generate a DC voltage based on the AC voltage. The DC voltage is input to the constant current circuit 130. In this embodiment, the smoothing circuit 120 has a diode 121 and a capacitor 122. The capacitor 122 is, for example, an electrolytic capacitor. Note that the diode 121 may be omitted in the smoothing circuit 120.

[0036] The constant current circuit 130 generates a constant current based on the DC voltage input from the smoothing circuit 120. The constant current generated by the constant current circuit 130 is supplied to the light source unit 200.

[0037] The light source unit 200 generates light based on the constant current supplied from the constant current circuit 130. Specifically, the light source unit 200 has a light source 210. The light source 210 emits light. The light source 210 has one or more light-emitting elements 211. FIG. 4 illustrates two light-emitting elements 211 connected in series. For example, the light source 210 has a white LED (Light Emitting Diode) as the light-emitting element 211. The light source 210 is, for example, a surface mount device (SMD) element or a chip on board (COB) element.

[0038] The switch unit 160 switches the light source unit 200 between on and off. Specifically, the switch unit 160 has a switch element 161. The switch element 161 is connected in series with the light emitting element 211. When the switch element 161 is in an on state, a constant current flows through the light emitting element 211, causing the light emitting element 211 to emit light. When the switch element 161 is in an off state, the supply of the constant current to the light emitting element 211 is cut off, causing the light emitting element 211 to stop emitting light. The switch element 161 may be, for example, a semiconductor switch. In this embodiment, the switch element 161 is an NchMOSFET.

[0039] The wireless communication unit 300 is capable of wireless communication with a communication device that complies with the same communication standard. In this embodiment, the wireless communication unit 300 performs communication with the bridge 4 that complies with a first communication standard. The wireless communication unit 300 performs wireless communication that complies with a short-range wireless standard such as ZIGBEE (registered trademark). The wireless communication unit 300 is, for example, a wireless LAN adapter.

[0040] The wireless communication unit 300 receives a command signal from the bridge 4. Specifically, as described with reference to Fig. 1, the wireless communication unit 300 receives a signal including a turn-off command or a turn-on command as command information from the bridge 4. When the wireless communication unit 300 receives a command signal from the bridge 4, it converts the signal into a signal conforming to a fourth communication standard and transmits the signal to the first lighting control unit 140A. The fourth communication standard may be, for example, a serial communication standard conforming to the UART standard or the I2C standard.

[0041] The first lighting control unit 140A is, for example, a CPU (Central Processing The first lighting control unit 140A may have a processor such as a Micro Processing Unit (MPU) or a Micro Processing Unit (MCU). Alternatively, the first lighting control unit 140A may have a processor such as a Micro Controller Unit (MCU).

[0042] When the first input terminal 11a and the second input terminal 11b are electrically connected to the AC power supply A and the first lighting control unit 140A is powered on, the first lighting control unit 140A executes a startup process to start up the wireless communication unit 300. The startup process will be described later with reference to FIG.

[0043] When the first lighting control unit 140A receives a signal including a lighting command from the wireless communication unit 300, it controls the switch unit 160 so that the light source unit 200 lights up. In detail, the first lighting control unit 140A turns on the switch element 161. As a result, light is generated from the light source unit 200. The first lighting control unit 140A of this embodiment controls the gate terminal of the NchMOSFET which is the switch element 161 to turn on the switch element 161.

[0044] When the first lighting control unit 140A receives a signal including a turn-off command from the wireless communication unit 300, it controls the switch unit 160 to turn off the light source unit 200. More specifically, the first lighting control unit 140A turns off the switch element 161. As a result, the light source unit 200 is turned off. The first lighting control unit 140A of this embodiment controls the gate terminal of the NchMOSFET, which is the switch element 161, to turn off the switch element 161.

[0045] The first storage unit 150A stores various data. The first storage unit 150A also stores a first lighting program. The first lighting program defines the processing executed by the first lighting control unit 140A. The first storage unit 150A has a semiconductor memory such as a RAM (Random Access Memory) and a ROM (Read Only Memory).

[0046] In addition, when the first lighting control unit 140A has an MCU, the first storage unit 150A may be omitted. In this case, the MCU stores various data and the first lighting program.

[0047] Next, the first illumination control unit 140A, the first storage unit 150A, and the wireless communication unit 300 will be further described with reference to Fig. 3. Fig. 3 is a diagram showing the configurations of the first illumination control unit 140A, the first storage unit 150A, and the wireless communication unit 300 according to this embodiment.

[0048] 3, first storage unit 150A stores type information 151 and identification information 152. Type information 151 indicates the type of lighting device 1. Specifically, first storage unit 150A stores first type information 151A as type information 151. First type information 151A indicates the type of first lighting device 1A. More specifically, first type information 151A indicates an ON-OFF type.

[0049] 3, the wireless communication unit 300 includes an antenna 31, a transmission / reception unit 32, a communication control unit 33, and a storage unit 34. The antenna 31 receives a wireless signal from the bridge 4. The wireless signal is a signal in the RF (Radio Frequency) band.

[0050] The transceiver 32 demodulates the wireless signal received by the antenna 31 into a digital signal. The transceiver 32 also receives a digital signal from the communication control unit 33. The transceiver 32 modulates the digital signal received from the communication control unit 33 into a wireless signal. As a result, the wireless signal is transmitted from the antenna 31 to the bridge 4.

[0051] The communication control unit 33 has a logic circuit such as a field-programmable gate array (FPGA) or an application specific integrated circuit (ASIC). The communication control unit 33 converts the digital signal demodulated by the transceiver unit 32 into a signal conforming to the fourth communication standard described with reference to FIG. 2, and transmits the signal to the first lighting control unit 140A. As a result, a command signal is transmitted to the first lighting control unit 140A. The communication control unit 33 may have a processor such as a CPU, an MPU, or an MCU.

[0052] The storage unit 34 stores a communication program. The communication program defines the processing executed by the communication control unit 33. The storage unit 34 also stores various data. In this embodiment, the storage unit 34 stores type information 151 and identification information 152. The storage unit 34 is, for example, a rewritable non-volatile memory such as an EEPROM (registered trademark).

[0053] Type information 151 is stored in storage 34 during a start-up process, which will be described later with reference to Fig. 4. First type information 151A is stored as type information 151 in storage 34 of wireless communication unit 300 mounted in first lighting fixture 1A.

[0054] The identification information 152 is stored in the storage unit 34 after execution of a startup process described later with reference to Fig. 4. Specifically, the first lighting control unit 140A reads out the identification information 152 from the first storage unit 150A and transmits a signal indicating the identification information 152 to the communication control unit 33, and the communication control unit 33 stores the identification information 152 in the storage unit 34.

[0055] The communication control unit 33 controls the transceiver unit 32 so that a signal indicating the type information 151 and the identification information 152 is transmitted to the bridge 4. Specifically, the communication control unit 33 transmits a digital signal indicating the type information 151 and the identification information 152 to the transceiver unit 32. The transceiver unit 32 modulates the digital signal received from the communication control unit 33 into a wireless signal. As a result, a signal indicating the type information 151 and the identification information 152 is transmitted from the antenna 31 to the bridge 4. Hereinafter, the type information 151 and the identification information 152 may be collectively referred to as "setting information". Furthermore, the signal indicating the setting information may be referred to as a "setting signal".

[0056] A setting signal transmission process for transmitting a setting signal to the bridge 4 is executed after a start-up process described later with reference to Fig. 4. Alternatively, the setting signal transmission process is executed when the bridge 4 requests the wireless communication unit 300 to transmit the type information 151 and the identification information 152. Alternatively, the setting signal transmission process is executed when the wireless communication unit 300 and the bridge 4 execute a process for authenticating each other.

[0057] Next, the startup process executed by the first lighting control unit 140A and the communication control unit 33 will be described with reference to Fig. 3 and Fig. 4. Fig. 4 is a sequence diagram showing the startup process according to this embodiment. The startup process is executed every time the first lighting control unit 140A is powered on.

[0058] 4, when the first lighting control unit 140A is powered on, the first lighting control unit 140A commands the communication control unit 33 to start up (step (a)). As a result, the communication control unit 33 starts up.

[0059] When the communication control unit 33 is started, it notifies the first lighting control unit 140A of the start-up (step (b)). When the first lighting control unit 140A confirms that the communication control unit 33 has started, it reads out the type information 151 from the first storage unit 150A and transmits a signal indicating the type information 151 to the communication control unit 33 (step (c)). Specifically, the first lighting control unit 140A transmits a signal indicating the first type information 151A to the communication control unit 33. When the communication control unit 33 receives the signal indicating the type information 151 (first type information 151A), it stores the type information 151 (first type information 151A) in the storage unit 34.

[0060] After storing type information 151 (first type information 151A) in memory unit 34, the communications control unit 33 reads out type information 151 (first type information 151A) from memory unit 34, and transmits a signal indicating type information 151 (first type information 151A) to first lighting control unit 140A (step (d)), thereby completing the startup process.

[0061] The first lighting control unit 140A confirms that the type information 151 (first type information 151A) received from the communication control unit 33 matches the type information 151 (first type information 151A) stored in the first memory unit 150A, and terminates the startup process.

[0062] Next, the second lighting fixture 1B will be described with reference to Fig. 5. However, the description will focus on elements that are different from the first lighting fixture 1A, and detailed description of elements that are the same as those in the first lighting fixture 1A will be omitted.

[0063] Fig. 5 is a diagram showing the configuration of a second lighting device 1B according to this embodiment. As shown in Fig. 5, the second lighting device 1B includes a first input terminal 11a, a second input terminal 11b, a rectifier circuit 110, a smoothing circuit 120, a constant current circuit 130, a second lighting control unit 140B, a second storage unit 150B, a switch unit 160, a light source unit 200, and a wireless communication unit 300. The second lighting device 1B differs from the first lighting device 1A in the processing executed by the second lighting control unit 140B.

[0064] Second storage unit 150B stores a second lighting program. The second lighting program defines the processing executed by second lighting control unit 140B. Similarly to first storage unit 150A, second storage unit 150B stores type information 151. Specifically, second storage unit 150B stores second type information 151B as type information 151. Second type information 151B indicates the type of second lighting device 1B. More specifically, second type information 151B indicates a dimming type. Similarly to first storage unit 150A, second storage unit 150B further stores identification information 152 assigned to second lighting device 1B.

[0065] The second lighting control unit 140B inputs a PWM signal to the switch element 161 when the light source unit 200 is turned on. The frequency of the PWM signal is, for example, 100 Hz or more and 200 Hz or less. By inputting the PWM signal to the switch element 161, the switch element 161 is repeatedly turned on and off. Therefore, the light source unit 200 repeatedly turns on and off 100 times or more and 200 times or less per second. Since the frequency of the PWM signal is 100 Hz or more and 200 Hz or less, the light source unit 200 appears to be continuously lit to the human eye due to the afterimage effect.

[0066] When the first input terminal 11a and the second input terminal 11b are electrically connected to AC power supply A and the second lighting control unit 140B is powered on, the second lighting control unit 140B executes the startup process described with reference to Fig. 4, similar to the first lighting control unit 140A. As a result, type information 151 (second type information 151B) is stored in the wireless communication unit 300 of the second lighting device 1B.

[0067] Similarly to the first lighting control unit 140A, the second lighting control unit 140B reads out the identification information 152 from the second storage unit 150B and transmits a signal indicating the identification information 152 to the wireless communication unit 300. As a result, the identification information 152 is stored in the wireless communication unit 300 of the second lighting fixture 1B.

[0068] When the second lighting control unit 140B receives a signal including a lighting command from the wireless communication unit 300, it controls the switch unit 160 to turn on the light source unit 200. Specifically, the second lighting control unit 140B inputs a PWM signal to the switch element 161 to cause the light source 210 to emit light.

[0069] More specifically, the lighting command sent to the second lighting device 1B includes, in addition to a command to turn on the lighting device, light intensity information. The second lighting control unit 140B adjusts the duty ratio of the PWM signal based on the light intensity information. Specifically, the second lighting control unit 140B adjusts the length of the ON period of each pulse of the PWM signal. The length of the ON period indicates the length of the period during which the switch element 161 is in the ON state in one cycle of the PWM signal. By adjusting the duty ratio of the PWM signal based on the light intensity information obtained from the lighting command, the amount of light generated from the light source unit 200 when the lighting device is turned on can be controlled to the amount of light corresponding to the command from the remote control device 6 described with reference to FIG. 1.

[0070] When the second lighting control unit 140B receives a signal including a turn-off command from the wireless communication unit 300, it controls the switch unit 160 to turn off the light source unit 200. In detail, the second lighting control unit 140B stops inputting the PWM signal to the switch element 161 to turn off the switch element 161.

[0071] When the second lighting control unit 140B receives a signal including a dimming command from the wireless communication unit 300, it acquires light amount information from the dimming command and adjusts the amount of light generated from the light source unit 200. Specifically, the second lighting control unit 140B adjusts the amount of light generated from the light source unit 200 by adjusting the duty ratio of the PWM signal based on the light amount information acquired from the dimming command.

[0072] In detail, when the second lighting control unit 140B reduces the amount of light generated from the light source unit 200, it reduces the duty ratio of the PWM signal. In other words, it shortens the length of the ON period of each pulse of the PWM signal. On the other hand, when the second lighting control unit 140B increases the amount of light generated from the light source unit 200, it increases the duty ratio of the PWM signal. In other words, it lengthens the length of the ON period of each pulse signal of the PWM signal. In the following description, the amount of light generated from the light source unit 200 may be referred to as the "light amount of the light source unit 200".

[0073] Similar to the wireless communication unit 300 of the first lighting device 1A, the wireless communication unit 300 of the second lighting device 1B includes the antenna 31, the transceiver unit 32, the communication control unit 33, and the storage unit 34 described with reference to FIG.

[0074] When the wireless communication unit 300 of the second lighting fixture 1B is commanded to start up by the second lighting control unit 140B, it executes the start-up process described with reference to Fig. 4. Therefore, the wireless communication unit 300 stores type information 151 (second type information 151B). Similarly to the wireless communication unit 300 of the first lighting fixture 1A, the wireless communication unit 300 of the second lighting fixture 1B also executes a setting signal transmission process.

[0075] Next, a third lighting fixture 1C will be described with reference to Fig. 6. However, the description will focus on elements that are different from the first lighting fixture 1A and the second lighting fixture 1B, and detailed description of elements that are the same as the first lighting fixture 1A and the second lighting fixture 1B will be omitted.

[0076] Fig. 6 is a diagram showing the configuration of a third lighting device 1C according to this embodiment. As shown in Fig. 6, the third lighting device 1C includes a first input terminal 11a, a second input terminal 11b, a rectifier circuit 110, a smoothing circuit 120, a constant current circuit 130, a third lighting control unit 140C, a third storage unit 150C, a switch unit 160, a light source unit 200, and a wireless communication unit 300. The third lighting device 1C differs from the first lighting device 1A and the second lighting device 1B in the configurations of the switch unit 160 and the light source unit 200. Furthermore, the third lighting device 1C differs from the first lighting device 1A and the second lighting device 1B in the processing executed by the third lighting control unit 140C.

[0077] The light source unit 200 of the third lighting device 1C has a first light source 210a and a second light source 210b. The first light source 210a and the second light source 210b emit light of different colors.

[0078] Specifically, the first light source 210a generates light of a first light color. More specifically, the first light source 210a has one or more first light-emitting elements 211a. FIG. 6 illustrates two first light-emitting elements 211a connected in series. The light of the first light color is, for example, light with a correlated color temperature of 2700 Kelvin (warm light). The second light source 210b generates light of a second light color different from the first light color. More specifically, the second light source 210b has one or more second light-emitting elements 211b. FIG. 6 illustrates two second light-emitting elements 211b connected in series. The light of the second light color is, for example, light with a correlated color temperature of 5000 Kelvin (cool light).

[0079] The switch section 160 of the third lighting device 1C has a first switch element 161a and a second switch element 161b. The first switch element 161a is connected in series to the first light source 210a. The second switch element 161b is connected in series to the second light source 210b.

[0080] The third lighting control unit 140C controls the switch unit 160 when the light source unit 200 is turned on to adjust the amount and color of light generated from the light source unit 200. Specifically, when the light source unit 200 is turned on, the third lighting control unit 140C generates at least one of a first PWM signal to be input to the first switch element 161a and a second PWM signal to be input to the second switch element 161b.

[0081] When the first PWM signal is input to the first switch element 161a, light of the first light color is generated from the first light source 210a. Therefore, the third illumination control unit 140C can adjust the light color of the light generated from the light source unit 200 to the first light color by generating only the first PWM signal out of the first PWM signal and the second PWM signal. In the following description, the light color of the light generated from the light source unit 200 may be referred to as the "light color of the light source unit 200."

[0082] When the second PWM signal is input to the second switch element 161b, the second light source 210b generates light of the second light color. Therefore, the third illumination control unit 140C can adjust the light color of the light source unit 200 to the second light color by generating only the second PWM signal out of the first PWM signal and the second PWM signal.

[0083] In addition, the third illumination control unit 140C can adjust the amount of light of the first light color by adjusting the duty ratio of the first PWM signal. Therefore, when the third illumination control unit 140C generates light of the first light color from the light source unit 200, the third illumination control unit 140C can adjust the amount of light of the light source unit 200 by adjusting the duty ratio of the first PWM signal.

[0084] The third illumination control unit 140C can adjust the amount of light of the second light color by adjusting the duty ratio of the second PWM signal. Therefore, when the light source unit 200 generates light of the second light color, the third illumination control unit 140C can adjust the amount of light of the light source unit 200 by adjusting the duty ratio of the second PWM signal.

[0085] When a first PWM signal is input to the first switch element 161a and a second PWM signal is input to the second switch element 161b, light of the first light color is generated from the first light source 210a and light of the second light color is generated from the second light source 210b. Therefore, when the third illumination control unit 140C generates the first PWM signal and the second PWM signal, light in which the light of the first light color and the light of the second light color are mixed is generated from the light source unit 200. Hereinafter, the light in which the light of the first light color and the light of the second light color are mixed may be referred to as "mixed light."

[0086] The third lighting control unit 140C can adjust the amount of light of the mixed light (the amount of light of the light source unit 200) by adjusting the duty ratio of the first PWM signal and the second PWM signal. Also, the third lighting control unit 140C can adjust the light color of the mixed light (the light color of the light source unit 200) by adjusting the duty ratio of the first PWM signal and the second PWM signal. Specifically, the third lighting control unit 140C adjusts the ratio between the amount of light of the first light color and the amount of light of the second light color by adjusting the duty ratio of the first PWM signal and the second PWM signal. As a result, the light color of the mixed light is adjusted.

[0087] The third storage unit 150C stores a third lighting program. The third lighting program defines the processing executed by the third lighting control unit 140C. Similarly to the first storage unit 150A and the second storage unit 150B, the third storage unit 150C stores type information 151. Specifically, the third storage unit 150C stores third type information 151C as the type information 151. The third type information 151C indicates the type of the third lighting device 1C. More specifically, the third type information 151C indicates the dimming / color adjustment type. Similarly to the first storage unit 150A and the second storage unit 150B, the third storage unit 150C further stores identification information 152 assigned to the third lighting device 1C.

[0088] When the first input terminal 11a and the second input terminal 11b are electrically connected to AC power supply A and the third lighting control unit 140C is powered on, the third lighting control unit 140C executes the startup process described with reference to Fig. 4, similar to the first lighting control unit 140A and the second lighting control unit 140B. As a result, type information 151 (third type information 151C) is stored in the wireless communication unit 300 of the third lighting device 1C.

[0089] Similarly to the first and second lighting control sections 140A and 140B, the third lighting control section 140C reads out the identification information 152 from the third storage section 150C and transmits a signal indicating the identification information 152 to the wireless communication section 300. As a result, the identification information 152 is stored in the wireless communication section 300 of the third lighting fixture 1C.

[0090] When the third lighting control unit 140C receives a signal including a lighting command from the wireless communication unit 300, it controls the switch unit 160 to turn on the light source unit 200. In detail, the lighting command transmitted to the third lighting device 1C includes light intensity information and light color information in addition to a lighting command. For example, when generating mixed light from the light source unit 200, the third lighting control unit 140C generates a first PWM signal and a second PWM signal. In addition, the third lighting control unit 140C adjusts the duty ratio of the first PWM signal and the second PWM signal based on the light intensity information and light color information acquired from the lighting command. As a result, the light color and light intensity of the light source unit 200 are controlled to the light color and light intensity corresponding to the command from the remote control device 6 described with reference to FIG. 1.

[0091] When the third lighting control unit 140C receives a signal including a turn-off command from the wireless communication unit 300, it controls the switch unit 160 to turn off the light source unit 200. For example, when light mixing occurs from the light source unit 200, the third lighting control unit 140C stops inputting the first PWM signal to the first switch element 161a and the second PWM signal to the second switch element 161b to turn off the first switch element 161a and the second switch element 161b.

[0092] When the third lighting control unit 140C receives a signal including a dimming command from the wireless communication unit 300, it acquires light amount information from the dimming command and adjusts the light amount of the light source unit 200. For example, when light mixing occurs from the light source unit 200, the third lighting control unit 140C adjusts the light amount of the light source unit 200 by adjusting the duty ratio of the first PWM signal and the second PWM signal based on the light amount information acquired from the dimming command.

[0093] When the third illumination control unit 140C receives a signal including a color adjustment command from the wireless communication unit 300, it acquires light color information from the color adjustment command and adjusts the color adjustment of the light source unit 200.

[0094] For example, when adjusting the light color of the mixed light, the third lighting control unit 140C adjusts the light color of the light source unit 200 by adjusting the duty ratios of the first PWM signal and the second PWM signal based on the light color information acquired from the color adjustment command.

[0095] In addition, when the light color information obtained from the color adjustment command indicates the first light color, the third lighting control unit 140C generates only the first PWM signal of the first PWM signal and the second PWM signal to adjust the light color of the light source unit 200 to the first light color.

[0096] Similarly, when the light color information obtained from the color adjustment command indicates the second light color, the third lighting control unit 140C generates only the second PWM signal of the first PWM signal and the second PWM signal to adjust the light color of the light source unit 200 to the second light color.

[0097] The wireless communication unit 300 of the third lighting fixture 1C, like the wireless communication units 300 of the first lighting fixture 1A and the second lighting fixture 1B, is equipped with the antenna 31, the transceiver unit 32, the communication control unit 33, and the memory unit 34 described with reference to FIG. 3.

[0098] When the wireless communication unit 300 of the third lighting fixture 1C is commanded to start up by the third lighting control unit 140C, it executes the start-up process described with reference to Fig. 4. Therefore, the wireless communication unit 300 stores type information 151 (third type information 151C). The wireless communication unit 300 of the third lighting fixture 1C also executes a setting signal transmission process, similar to the wireless communication units 300 of the first lighting fixture 1A and the second lighting fixture 1B.

[0099] Next, the configuration of the bridge 4 will be described with reference to Fig. 7. Fig. 7 is a diagram showing the configuration of the bridge 4 according to this embodiment. As shown in Fig. 7, the bridge 4 includes a wireless communication unit 41, a wired communication unit 42, a control unit 43, and a storage unit 44.

[0100] The wireless communication unit 41 is capable of wireless communication with a communication device that complies with the same communication standard. In this embodiment, the wireless communication unit 41 performs communication with the first lighting fixture 1A, the second lighting fixture 1B, and the third lighting fixture 1C that complies with the first communication standard. The wireless communication unit 41 performs wireless communication that complies with a short-range wireless standard such as ZIGBEE (registered trademark). The wireless communication unit 41 is, for example, a wireless LAN adapter. Note that FIG. 7 illustrates a state in which the wireless communication unit 41 and the second lighting fixture 1B are communicating with each other.

[0101] The wired communication unit 42 is capable of communicating with a communication device conforming to the same communication standard. In this embodiment, the wired communication unit 42 performs communication conforming to the second communication standard with the router 5 via a cable. The wired communication unit 42 is, for example, an adapter for serial communication such as Ethernet (registered trademark).

[0102] The control unit 43 has a processor such as a CPU or MPU. Alternatively, the control unit 43 may have a processor such as an MCU. The memory unit 44 stores various data. The memory unit 44 also stores a bridge program. The bridge program defines the processing executed by the control unit 43. The memory unit 44 has semiconductor memory such as a RAM and a ROM. The control unit 43 controls the wireless communication unit 41, the wired communication unit 42, and the memory unit 44 by executing the bridge program.

[0103] For example, control unit 43 causes data received by wired communication unit 42 from router 5 to be transmitted from wireless communication unit 41 to first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C. As a result, a signal conforming to the second communication standard received by wired communication unit 42 is converted into a signal conforming to the first communication standard and transmitted to first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C.

[0104] Similarly, control unit 43 causes data received by wireless communication unit 41 from first lighting fixture 1A, second lighting fixture 1B, or third lighting fixture 1C to be transmitted from wired communication unit 42 to router 5. As a result, the signal conforming to the first communication standard received by wireless communication unit 41 is converted into a signal conforming to the second communication standard and transmitted to router 5.

[0105] In addition, when the control unit 43 has an MCU, the storage unit 44 may be omitted. In this case, the MCU stores various data and the bridge program. In addition, the control unit 43 may be configured with a logic circuit such as an FPGA or an ASIC instead of a processor.

[0106] In this embodiment, the wireless communication unit 41 receives setting signals from each of the first lighting fixture 1A, the second lighting fixture 1B, and the third lighting fixture 1C. The control unit 43 obtains setting information (type information 151 and identification information 152) from the setting signals and stores them in the memory unit 44. After storing the setting information in the memory unit 44, the control unit 43 causes the wired communication unit 42 to transmit a setting signal to the router 5. As a result, the setting signal is transmitted from the router 5 to the remote control device 6 described with reference to FIG. 1.

[0107] Furthermore, wired communication unit 42 receives a command signal from router 5. When wired communication unit 42 receives the command signal from router 5, control unit 43 determines a destination lighting fixture 1 from among first lighting fixture 1A, second lighting fixture 1B, and third lighting fixture 1C. Then, control unit 43 controls wireless communication unit 41 to transmit the command signal to the determined destination lighting fixture 1.

[0108] Next, the configuration of the remote control device 6 will be described with reference to Fig. 8. Fig. 8 is a diagram showing the configuration of the remote control device 6 according to this embodiment. As shown in Fig. 8, the remote control device 6 includes a wireless communication unit 61, a display unit 62, an input unit 63, a display control unit 64, and a storage unit 65.

[0109] The wireless communication unit 61 is capable of wireless communication with a communication device that complies with the same communication standard. In this embodiment, the wireless communication unit 61 performs communication with the router 5 that complies with a third communication standard. The wireless communication unit 61 performs wireless communication that complies with a wireless LAN standard such as Wi-Fi (registered trademark). The wireless communication unit 61 is, for example, a wireless LAN adapter.

[0110] The display unit 62 displays various screens. The display unit 62 is, for example, a display such as a liquid crystal display or an organic EL (Electro-Luminescence) display. In this embodiment, the display unit 62 displays a lighting control screen G, which will be described with reference to FIG. 9. The input unit 63 inputs a user's operation. In this embodiment, the input unit 63 is a touch sensor. The touch sensor is superimposed on the display surface of the display unit 62. Therefore, the display unit 62 and the input unit 63 configure a touch panel.

[0111] The display control unit 64 has a processor such as a CPU or MPU. The storage unit 65 stores various data. The storage unit 65 also stores an application for lighting control. The application for lighting control includes operation screen information 651. The storage unit 65 has, for example, semiconductor memory such as a RAM and a ROM.

[0112] In this embodiment, the wireless communication unit 61 receives a setting signal from the router 5. The display control unit 64 acquires setting information (type information 151 and identification information 152) from the setting signal received by the wireless communication unit 61 and stores it in the storage unit 65.

[0113] Furthermore, the display control section 64 executes a lighting control application to cause the display section 62 to display a lighting control screen G, which will be described with reference to Fig. 9. In particular, the operation screen information 651 includes information relating to the layout of the lighting control screen G. The display control section 64 adjusts the layout of the lighting control screen G based on the type information 151. In other words, the display control section 64 adjusts the layout of the lighting control screen G to a layout corresponding to the type information 151.

[0114] The display control unit 64 generates command information for controlling the lighting fixture 1 based on an operation input to the input unit 63 while the lighting control screen G is being displayed. Then, the display control unit 64 causes the wireless communication unit 61 to transmit a command signal to the router 5.

[0115] Next, the lighting control screen G will be described with reference to Fig. 8 and Fig. 9. Fig. 9 is a diagram showing an example of the lighting control screen G according to the present embodiment. As shown in Fig. 9, the display control unit 64 causes the display unit 62 to display the lighting control screen G. Specifically, the display control unit 64 creates the lighting control screen G based on the operation screen information 651, the identification information 152, and the type information 151. The lighting control screen G of the present embodiment includes a first control screen G1, a second control screen G2, and a third control screen G3.

[0116] The first control screen G1 is a screen for controlling the first lighting fixture 1A. The first control screen G1 includes a light on / off operation section 71. The display controller 64 creates the first control screen G1 based on the operation screen information 651, the identification information 152 of the first lighting fixture 1A, and the first type information 151A.

[0117] The on / off operation unit 71 is a button for issuing a command to turn the light on or off. The user can issue a command to turn the first lighting fixture 1A on or off by operating the on / off operation unit 71 on the first control screen G1. Specifically, when the on / off operation unit 71 on the first control screen G1 is operated, the display control unit 64 causes the wireless communication unit 61 to transmit a command signal to the router 5. Here, the command signal includes the identification information 152 of the first lighting fixture 1A, the first type information 151A, and a command to turn the light off or on. As a result, the first lighting fixture 1A is turned on or off.

[0118] The second control screen G2 is a screen for controlling the second lighting device 1B. The second control screen G2 includes a light on / off operation section 71 and a dimming operation section 72. The display controller 64 creates the second control screen G2 based on the operation screen information 651, the identification information 152 of the second lighting device 1B, and the second type information 151B.

[0119] The dimming operation unit 72 has a slider for specifying the light intensity. The user can adjust the light intensity of the second lighting device 1B by operating the dimming operation unit 72 on the second control screen G2. Specifically, when the dimming operation unit 72 on the second control screen G2 is operated, the display controller 64 causes the wireless communication unit 61 to transmit a command signal to the router 5. Here, the command signal includes the identification information 152 of the second lighting device 1B, the second type information 151B, and a dimming command. As a result, the light intensity of the light emitted from the second lighting device 1B is adjusted.

[0120] The third control screen G3 is a screen for controlling the third lighting fixture 1C. The third control screen G3 includes a light on / off operation section 71, a dimming operation section 72, and a color adjustment operation section 73. The display controller 64 creates the third control screen G3 based on the operation screen information 651, the identification information 152 of the third lighting fixture 1C, and the third type information 151C.

[0121] The color adjustment operation unit 73 has a slider for specifying a light color. The user can adjust the color of the light emitted from the third lighting device 1C by operating the color adjustment operation unit 73 of the third control screen G3. Specifically, when the color adjustment operation unit 73 of the third control screen G3 is operated, the display control unit 64 causes the wireless communication unit 61 to transmit a command signal to the router 5. Here, the command signal includes the identification information 152 of the third lighting device 1C, the third type information 151C, and a color adjustment command. As a result, the color of the light emitted from the third lighting device 1C is adjusted.

[0122] An embodiment of the present invention has been described above. According to this embodiment, type information 151 is stored (set) in wireless communication unit 300 when first lighting control unit 140A to third lighting control unit 140C are powered on. Therefore, there is no need to set type information 151 in wireless communication unit 300 in advance. Therefore, according to this embodiment, there is no need to manufacture a wireless communication unit 300 for each type of lighting device 1.

[0123] Furthermore, according to this embodiment, the layout of lighting control screen G is adjusted to a layout corresponding to the type of lighting fixture 1. For example, first control screen G1 corresponds to an ON-OFF type lighting fixture 1, and therefore includes only the ON / OFF operation section 71 out of the ON / OFF operation section 71, the dimming operation section 72, and the color adjustment operation section 73. Therefore, according to this embodiment, it is possible to prevent erroneous input of an instruction to adjust the color or dimming of an ON-OFF type lighting fixture 1, for example.

[0124] Furthermore, according to this embodiment, when AC power source A is electrically connected to first input terminal 11a and second input terminal 11b of lighting fixture 1, type information 151 is stored (set) in wireless communication unit 300. Therefore, a worker installing lighting fixture 1 in an office or the like does not need to set type information 151 in wireless communication unit 300 after electrically connecting AC power source A to first input terminal 11a and second input terminal 11b of lighting fixture 1. This reduces the burden on the worker.

[0125] The present invention is not limited to the above-described embodiment, and can be embodied in various forms without departing from the spirit and scope of the present invention. In addition, the components disclosed in the above-described embodiment can be modified as appropriate.

[0126] For example, in an embodiment according to the present invention, the lighting system 100 includes three types of lighting fixtures 1, but the lighting system 100 may include two types of lighting fixtures 1 or only one type of lighting fixture 1.
