[0009] <1. First embodiment> <1.1. Overview> Hereinafter, a lighting system 40 according to an embodiment of the present invention will be described in detail with reference to the drawings. In the following description, identical parts included in common in the referenced drawings will be assigned the same reference numerals, and duplicated descriptions of the identical parts will be omitted as a general rule.

[0010] FIG. 1 is a diagram showing the connection relationship between a lighting system 40 according to a first embodiment of the present invention, and a projector 20 and a blind 50 that are linked to the lighting system 40. As shown in FIG.

[0011] The lighting system 40 is a system that controls lighting in conjunction with the operation of other devices. In this embodiment, the lighting system 40 is linked with a projector 20 and blinds 50, which are examples of other devices. The lighting system 40 dims the lights and closes the blinds 50 when the projector 20 projects an image, thereby helping the user to become immersed in the image and sound while watching the image.

[0012] In the lighting system 40, the contact-linked remote control 10 realizes a variety of linked operations with the projector 20 and the blinds 50 using a limited number of input contact signals.

[0013] <1.2.Configuration> The configurations of the lighting system 40, the projector 20, and the blinds 50 will be described in detail below.

[0014] <1.2.1 Projector 20, Blinds 50> Projector 20 is an example of a contact signal output device that cooperates with lighting fixtures LF1 to LF28, and projects images, etc. Projector 20 outputs a contact signal from an output terminal to lighting system 40 in response to a user's instruction to start operation and an instruction to stop operation. A user's instruction to projector 20 to start operation is, for example, a user's instruction to projector 20 to start image projection, and a user's instruction to projector 20 to stop image projection is, for example, a user's instruction to projector 20 to stop image projection.

[0015] The blinds 50 are an example of a lighting interlocking device that works in conjunction with lighting fixtures, and are installed in windows, etc., in rooms in an office building to limit the amount of light entering the room through the windows, etc. Specifically, the blinds 50 are equipped with slats, and limit the amount of light entering the room through the windows, etc., by raising and lowering the slats on the blinds 50 and by opening and closing the slats by rotating them.

[0016] The contact signal is output to the blinds 50 when the dimming rate of the lighting fixtures included in the lighting system 40 exceeds a predetermined first threshold value, or when the dimming rate falls below a predetermined second threshold value.

[0017] <1.2.2. Lighting System 40> The configuration of lighting system 40 will be described with reference to Fig. 1. Lighting system 40 includes 28 lighting fixtures LF1 to LF28, a gateway 45 that functions as a control device for lighting system 40, a tablet 46 as an example of an information communication device, and contact-linked remote control 10.

[0018] The lighting fixture LFn (n represents any one of 1 to 28) and the gateway 45 communicate wirelessly with each other. The gateway 45 and the contact-linked remote control 10 communicate wirelessly with each other. The gateway 45 and the tablet 46 communicate wirelessly with each other.

[0019] Each lighting fixture LFn has a light source for lighting and illuminates the surrounding area where the lighting fixture LFn is installed. The lighting fixture LFn operates based on a lighting control signal received from the contact-linked remote control 10 via the gateway 45. The lighting control signal is a signal for controlling the lighting fixture LFn.

[0020] Lighting fixtures LF1 to LF19 belong to group 401, and lighting fixtures LF20 to LF28 belong to group 402. Each lighting fixture LFn is controlled by group, and each group performs operations such as turning on and off the light source, changing the dimming rate, and changing the color adjustment rate. Each lighting fixture LFn can also be controlled individually.

[0021] Gateway 45 receives a control instruction from contact-linked remote control 10 and transmits a lighting control signal to lighting fixture LFn in accordance with the content of the received control instruction. Gateway 45 may also receive an instruction from tablet 46 and transmit a lighting control signal to lighting fixture LFn in accordance with the content of the received instruction.

[0022] Tablet 46 is a portable information terminal device having a rectangular plate-like appearance and a touch panel 461 fitted on one surface. Tablet 46 has a function of displaying a user interface (hereinafter referred to as "UI") on touch panel 461.

[0023] In response to the user input, the tablet 46 transmits to the contact-linked remote control 10 a registration request corresponding to the content of the operation to be performed by the lighting fixture LFn belonging to the group 401 or the group 402. The tablet 46 also controls the lighting fixture LFn in response to the user input.

[0024] <1.2.3. Contact-linked remote control 10> The contact-linked remote control 10 is a device that controls the lighting fixture LFn in conjunction with a contact signal input thereto. Specifically, the contact-linked remote control 10 transmits a control instruction in response to the contact signal input from the contact signal output device, thereby controlling the lighting fixture LFn.

[0025] When contact-linked remote control 10 detects a specific signal portion of a contact signal input from projector 20, which is a contact signal output device, it transmits a control instruction to control lighting fixture LFn.

[0026] The contact-linked remote control 10 has a control instruction table including detection settings for the specific signal portion. In addition, the projector 20 and the blinds 50 are wired connected to the contact-linked remote control 10. The specific signal portion of the contact signal and the detection of the specific signal portion will be described later.

[0027] Fig. 2 is a block diagram showing the functional configuration of the contact-linked remote control 10. Fig. 3 is an enlarged view of the top surface of the contact-linked remote control 10.

[0028] The contact-linked remote control 10 includes a control unit 11, a storage unit 12, an input / output unit 13, and a power supply unit 15 as functional units.

[0029] The storage unit 12 stores data such as a program for operating the control unit 11 and a control instruction table including contact signal detection settings. The control instruction table will be described in detail later. The storage unit 12 provides the stored programs, data, etc. to the control unit 11. The storage unit 12 is also used as a work area for the control unit 11.

[0030] The storage unit 12 includes a nonvolatile storage medium such as a flash memory that allows data to be added and changed, and a volatile storage medium such as a RAM (Random Access Memory). The nonvolatile storage medium in the storage unit 12 stores programs and data for operating the control unit 11, as well as the contents of a control instruction table. The volatile storage medium in the storage unit 12 is used as a work area for the control unit 11, into which programs for operating the control unit 11 are loaded.

[0031] The input / output unit 13 communicates with the outside of the contact-linked remote control 10 via wired or wireless communication to input and output signals and information. The input / output unit 13 includes a contact input unit 131, a contact output unit 132, a wireless communication unit 133, a test unit 134, a display unit 135, and an initialization unit 136.

[0032] The contact input unit 131 receives a contact signal from an external device. The contact input unit 131 has input terminals A1 to A6. Each of the input terminals A1 to A6 has a terminal to which a pair of signal lines can be connected.

[0033] In this embodiment, the input terminal A1 is connected to the contact output terminal of the projector 20 via a signal line, and receives the contact signal output from the projector 20.

[0034] The contact output unit 132 outputs a contact signal to an external device. The contact output unit 132 has output terminals B1 to B6. Each of the output terminals B1 to B6 is a terminal to which a pair of signal lines can be connected. In this embodiment, the signal line connected to the contact input terminal of the blind 50 is connected to the output terminal B1.

[0035] The wireless communication unit 133 communicates wirelessly with the gateway 45. The wireless communication unit 133 also communicates wirelessly with the tablet 46 and the lighting fixture LFn via the gateway 45. The wireless communication unit 133 has, for example, a MAC address as identification information for wireless communication. The MAC address held by the wireless communication unit 133 is used as an address for wireless communication.

[0036] The test unit 134 has a function of issuing a control instruction to the control unit 11 to check the operation of the lighting system 40 when a contact signal is input, or an instruction to output a contact signal to check the operation of the blinds 50, regardless of whether a contact signal output device is connected. The test unit 134 includes operation check buttons BA1-6 and BB1-6, as shown in Fig. 3. When each of the operation check buttons BA1-6 is pressed, the test unit 134 instructs the control unit 11 to output a control instruction corresponding to each of the operation check buttons BA1-6 from the wireless communication unit 133.

[0037] When each of the operation check buttons BB1 to BB6 is pressed, the test section 134 causes the control section 11 to output a contact signal from each of the output terminals B1 to B6. For example, when the operation check button BB1 is pressed, the control section 11 causes the output terminal B1 to output a contact signal.

[0038] The display unit 135 displays the operating status of the contact-linked remote control 10. The display unit 135 includes indicators LA1 to LA6 and LB1 to LB6. The indicators LA1 to LA6 are LEDs (light-emitting diodes) that flash when a control instruction corresponding to the input terminals A1 to A6 is output.

[0039] The number of times indicators LA1 to LA6 blink depends on the number of specific signal parts detected at input terminals A1 to A6. Indicators LA1 to LA6 blink twice if the number of specific signal parts detected at input terminals A1 to A6 output from control unit 11 is even, and blink once if the number is odd.

[0040] The indicators LB1 to LB6 are LEDs that flash when contact signals are output from the output terminals B1 to B6.

[0041] The initialization unit 136 has a function of returning the contact-linked remote control 10 to its factory default state. The initialization unit 136 includes a reset button RST. The reset button RST is a button for returning the contact-linked remote control 10 to its factory default state. For example, when the initialization unit 136 detects that the reset button RST has been pressed for a predetermined period of time or longer, it returns the contact-linked remote control 10 to its factory default state. When the contact-linked remote control 10 is returned to its factory default state, the contents of the control instruction table and the like stored in the memory unit 12 are erased.

[0042] The control unit 11 controls the contact-linked remote control 10. The control unit 11 includes an IC (Integrated Circuit) or a CPU (Central Processing Unit), and controls the operation of the contact-linked remote control 10. When the contact input unit 131 detects a specific signal portion of a contact signal, the control unit 11 causes the wireless communication unit 133 to transmit a control instruction corresponding to the detected specific signal portion. When the transmitted control instruction satisfies a predetermined condition, the control unit 11 causes the contact output unit 132 to output the control instruction.

[0043] The control unit 11 includes counters that count the number of specific signal parts detected in the contact input unit 131 and the number of contact signals output by the contact output unit 132 for each of the input terminals A1 to A6 and the output terminals B1 to B6. Specifically, the control unit 11 counts the number of specific signal parts detected in each of the input terminals A1 to A6 included in the contact input unit 131 using the counter. The control unit 11 also counts the number of contact signals output from each of the output terminals B1 to B6 included in the contact output unit 132 using the counter.

[0044] The control unit 11 stores and preserves the number of specific signal parts detected for each of the input terminals A1 to A6 and the number of contact signals output for each of the output terminals B1 to B6 in a non-volatile memory provided in the storage unit 12. The control unit 11 also outputs whether the number of specific signal parts detected for each of the input terminals A1 to A6 and the number of contact signals output for each of the output terminals B1 to B6 are even or odd.

[0045] The power supply unit 15 is connected to a commercial power source by wire, and supplies power to each of the functional units included in the contact-linked remote control 10. The power supply unit 15 includes a power input terminal 151. The power supply unit 15 operates using power supplied from the commercial power source via the power input terminal 151, and supplies power to each of the functional units included in the contact-linked remote control 10.

[0046] <1.3. Detection of specific signal parts> FIG. 4 is a diagram for explaining the detection of the specific signal portion.

[0047] The specific signal parts of the contact signals inputted and outputted by the lighting system 40 include four types of specific signal parts, namely, a first specific signal part 1001 to a fourth specific signal part 1004 shown in FIG.

[0048] The first specified signal portion 1001 is a signal portion that continues from the rising edge 101 for a period equal to or longer than the reference pulse width Wref. The second specified signal portion 1002 is a signal portion that continues from the falling edge 103 for a period equal to or longer than the reference pulse width Wref. The third specified signal portion 1003 is a signal portion of both the rising edge 105 and the falling edge 106, each of which is counted by the control unit 11. The fourth specified signal portion 1004 is a signal portion of both the falling edge 107 and the rising edge 108, each of which is counted by the control unit 11.

[0049] The control unit 11 detects that a specific signal portion has been input to each of the input terminals A1 to A6 in accordance with the detection settings shown in the input control instruction table 5000.

[0050] There are four types of detection settings, namely, first detection setting to fourth detection setting, which are settings for detecting first specified signal part 1001 to fourth specified signal part 1004, respectively.

[0051] Specifically, when the detection setting of the input terminal is the first detection setting, the control unit 11 detects that a first specified signal unit 1001 has been input. Similarly, when the detection setting of the input terminal is the second detection setting, the control unit 11 detects that a second specified signal unit 1002 has been input. When the detection setting of the input terminal is the third detection setting, the control unit 11 detects that a third specified signal unit 1003 has been input. When the detection setting of the input terminal is the fourth detection setting, the control unit 11 detects that a fourth specified signal unit 1004 has been input.

[0052] <1.4. Data structure of control instruction table> The data structure of the control instruction table will now be described: The control instruction table includes an input control instruction table 5000 relating to input terminals and an output control instruction table 5500 relating to output terminals.

[0053] <1.4.1. Input Control Instruction Table 5000> FIG. 5 is a diagram showing the input control instruction table 5000.

[0054] Input control instruction table 5000 has, for each input terminal, detection setting 502, first control target 503, first control content 504, second control target 505, and second control content 506. Furthermore, row 521 in input control instruction table 5000 represents the setting when the input terminal is A1, and similarly, rows 522 to 526 represent the settings when the input terminals are A2 to A6, respectively.

[0055] Here, the first detection setting is a detection setting 502 in which the contact type is a contact, the contact mode is instantaneous, and the minimum pulse width is the reference pulse width Wref. The reference pulse width Wref is the length or time of a pulse that should maintain a predetermined contact signal state. The reference pulse width Wref is, for example, 10 mS.

[0056] First control object 503 and first control content 504 indicate the control object and control content when the number of specific signal parts detected by control unit 11 is odd when a specific signal part is detected. First control object 503 is, for example, lighting fixture LFn in group 401. First control content 504 is, for example, a dimming rate of 10% and a color temperature of 4200K.

[0057] The second control object 505 and the second control content 506 indicate the control object and the control content when the number of specific signal components detected by the control unit 11 is an even number. The second control object 505 is, for example, lighting fixture LFn in group 401. The second control content 506 is, for example, default lighting conditions. In this embodiment, the default lighting conditions are a dimming rate of 80% and a color temperature of 4200K.

[0058] In the second detection setting, in the detection setting 502, the contact type is a b-contact, the contact mode is instantaneous, and the minimum pulse width is the reference pulse width Wref.

[0059] The third detection setting is a contact type and a contact mode that is constant in the detection setting 502. When the contact mode is constant, the control unit 11 detects a continuous contact signal that is longer than a pulse, rather than a pulse-like contact signal.

[0060] In the fourth detection setting, in the detection setting 502, the contact type is the b-contact and the contact mode is normal.

[0061] <1.4.2. Output Control Instruction Table> FIG. 6 is a diagram showing the output control instruction table 5500.

[0062] Output control instruction table 5500 has detection settings 532 and output conditions 533 for each output terminal. Row 551 in output control instruction table 5500 represents settings when the output terminal is B1, and similarly, rows 552 to 556 represent settings when the output terminals are B2 to B6, respectively.

[0063] When output condition 533 shown in output control instruction table 5500 is satisfied for each of output terminals B1 to B6, control unit 11 outputs one of first to fourth specified signal units 1001 to 1004 in accordance with detection setting 532. For example, when third detection setting is made for a certain output terminal, third specified signal unit 1003 is output from that output terminal when output condition 533 is satisfied.

[0064] <1.5. Operation> The following describes the flow of processing performed in the lighting system 40 configured as described above. This processing is divided into registration processing, lighting control processing, and operation confirmation processing. The lighting control processing includes lighting interlocking processing.

[0065] The registration process is a process for registering the control content for lighting fixture LFn in the control instruction table stored in the contact interlocked remote control 10, so that the lighting system 40 can be controlled from the contact interlocked remote control 10. The lighting control process is a process for the contact interlocked remote control 10 to control lighting fixture LFn. The lighting interlocking process is a process performed on devices other than lighting fixture LFn based on the control content instructed in the lighting control process. The operation confirmation process is a process performed when the operation confirmation button is pressed.

[0066] <1.5.1. Registration process> In the registration process, the user registers and stores in advance in the storage unit 12 the control instructions and the like to be output by the contact-linked remote controller 10 .

[0067] In the registration process, the user inputs the contents of the detection setting 502, the first control target 503, the first control content 504, the second control target 505, and the second control content 506 in the input control instruction table 5000 into the tablet 46. The contents input by the user are transmitted as a registration request from the tablet 46 to the contact-linked remote control 10 via the gateway 45. The contact-linked remote control 10 registers the contents of the received registration request in the input control instruction table 5000 and stores them in the memory unit 12.

[0068] Similarly, the user inputs the contents of the detection settings 532 and output conditions 533 in the output control instruction table 5500 into the tablet 46. The contents input by the user are transmitted as a registration request from the tablet 46 to the contact-linked remote control 10 via the gateway 45. The contact-linked remote control 10 registers the contents of the received registration request in the output control instruction table 5500 and stores them in the memory unit 12.

[0069] This completes the registration process.

[0070] <1.5.2. Lighting control processing> <1.5.2.1. Overview> The lighting control process is a process by which the contact-linked remote control 10 controls the lighting fixture LFn. In this embodiment, the lighting control process is executed when using the projector 20. In the lighting control process, when the control unit 11 provided in the contact-linked remote control 10 detects a specific signal portion of the contact signal transmitted from the projector 20, it transmits a control instruction corresponding to the input terminal that detected the specific signal portion.

[0071] The lighting control process includes a lighting interlocking process. The lighting interlocking process is a process for controlling a lighting interlocking device that is interlocked and coordinated with lighting fixtures. In the lighting interlocking process, the control unit 11 causes the contact output unit 132 to output a contact signal based on the content of the control instruction given in the lighting control process.

[0072] Fig. 7 is a diagram for explaining the flow of the lighting control process, and Fig. 8 is a diagram for explaining the relationship between the specific signal part and the transmission timing of the control instruction.

[0073] <1.5.2.2. Contents of Input Control Instruction Table> In the following description, it is assumed that the output terminal of the projector 20 is connected to the input terminal A1 of the contact-linked remote control 10, and that the storage unit 12 stores the input control instruction table 5000 shown in FIG.

[0074] In the following description of the lighting control process, it is assumed that the number of contact signals received at input terminal A1, which is counted by a counter provided in control unit 11, before the start of the lighting control process is an odd number.

[0075] <1.5.2.3. Lighting control process flow> The flow of the illumination control process will be described below with reference to FIGS.

[0076] When the projector 20 receives an operation start instruction from the user, it outputs a contact signal to the input terminal A1 of the contact-linked remote control 10 (step S121, rising edge 141). The output of this contact signal starts the lighting control process. The output contact signal is assumed to be a signal with a contact type and a pulse width of 20 [mS].

[0077] 5, the detection setting of input terminal A1 is the first detection setting, and the reference pulse width Wref is 10 [mS]. Because the pulse width of the contact signal input to input terminal A1 is greater than the reference pulse width Wref, control unit 11 determines that first specified signal part 1001 has been detected at input terminal A1.

[0078] 8, when control unit 11 determines that it has detected first specified signal unit 1001, the number of specified signal units detected at input terminal A1 is odd. Therefore, control unit 11 causes first control target 503 registered for input terminal A1 to transmit a control instruction corresponding to first control content 504. Specifically, control unit 11 causes lighting fixture LFn in group 401 to transmit a control instruction with a dimming rate of 10% and a color temperature of 4200 K (step S123).

[0079] Furthermore, the control unit 11 adds 1 to the number of specific signal parts detected in the counter for input terminal A1, thereby changing the number of specific signal parts detected at input terminal A1 in the control unit 11 from an odd number to an even number.

[0080] The control target of the control instruction transmitted in step S123 is group 401. The control instruction transmitted from wireless communication unit 133 reaches gateway 45, which controls group 401 (step S123). Gateway 45 transmits a lighting control signal corresponding to the control instruction to lighting fixture LFn in group 401 (step S125).

[0081] The lighting fixtures LFn included in the group 401 operate in accordance with the lighting control signal (step S127). Specifically, the lighting fixtures LFn included in the group 401 illuminate with a dimming rate of 10% and a color temperature of 4200 K in accordance with the control content of the lighting control signal.

[0082] After step S123, the control unit 11 performs lighting interlocking processing (step S129). Details of the lighting interlocking processing will be explained after the explanation of the lighting control processing.

[0083] This completes the lighting control process.

[0084] In this embodiment, after projector 20 is turned on, the dimming rate of lighting fixture LFn can be automatically reduced at the timing of projecting an image. Therefore, this embodiment can help the user to be immersed in the video and audio while watching the video. Furthermore, this embodiment can eliminate the need to manually adjust the dimming rate of lighting fixture LFn in response to the operation of projector 20.

[0085] Thereafter, when the projector 20 receives an instruction to end operation from the user, it outputs a contact signal to the input terminal A1 of the contact-linked remote control 10 (step S121, rising edge 143). The output of this contact signal restarts the lighting control process. The output contact signal is assumed to be a signal with a contact type and a pulse width of 20 [mS].

[0086] 5, the detection setting of input terminal A1 is the first detection setting, and the reference pulse width Wref is 10 [mS]. Because the pulse width of the contact signal input to input terminal A1 is greater than the reference pulse width Wref, control unit 11 determines that first specified signal part 1001 has been detected at input terminal A1.

[0087] 8, when control unit 11 determines that it has detected first specific signal unit 1001, the number of specific signal units detected at input terminal A1 is an even number. Therefore, control unit 11 causes second control object 505 registered for input terminal A1 to transmit a control instruction corresponding to second control content 506. Specifically, control unit 11 causes lighting fixture LFn in group 401 to transmit a control instruction under default lighting conditions (step S123).

[0088] The control target of the control instruction transmitted in step S123 is group 401. The control instruction transmitted from wireless communication unit 133 reaches gateway 45 (step S125). Gateway 45 transmits a lighting control signal corresponding to the control instruction to lighting fixture LFn in group 401 (step S125).

[0089] The lighting fixtures LFn included in the group 401 operate in accordance with the lighting control signal (step S127). Specifically, the lighting fixtures LFn included in the group 401 illuminate under default conditions in accordance with the control content of the lighting control signal. In this embodiment, the default lighting conditions are a dimming rate of 80% and a color temperature of 4200 K.

[0090] After step S121, the control unit 11 performs lighting interlocking processing (step S129). Details of the lighting interlocking processing will be explained after the explanation of the lighting control processing.

[0091] This completes the lighting control process.

[0092] In this embodiment, the lighting conditions of the lighting fixture LFn are automatically restored to the default when the operation of the projector 20 is terminated. Therefore, in this embodiment, the user does not have difficulty in viewing the surroundings after the operation of the projector 20 is terminated. Furthermore, this embodiment eliminates the need for the user to manually adjust the dimming rate of the lighting fixture LFn in accordance with the operation of the projector 20.

[0093] In this embodiment, lighting fixture LFn is controlled based on the number of times a specific signal part is detected at each input terminal, allowing for a wide range of control even when the number of contact signals that can be received simultaneously is limited.

[0094] In this embodiment, the number of specific signal parts detected by the control unit 11 is stored and saved in a non-volatile memory provided in the storage unit 12. Therefore, even if the power supply to the contact-linked remote control 10 is interrupted for some reason after the user starts projecting an image with the projector 20, the lighting conditions can be returned to the default when the image projection with the projector 20 ends.

[0095] <1.5.2.4. Lighting interlocking processing> In the lighting control process, the control unit 11 performs a lighting interlocking process. In the lighting interlocking process, the control unit 11 causes the contact output unit 132 to output a control instruction to a device connected to the output terminal, based on the content of the control instruction transmitted in the lighting control process.

[0096] In this embodiment, control unit 11 outputs a contact signal as a control instruction to blinds 50 connected to output terminal B1 of contact output unit 132. Control unit 11 controls blinds 50 connected by wire to contact output unit 132 based on the dimming rate instructed to lighting fixture LFn in the lighting control process and a predetermined dimming rate threshold value.

[0097] Specifically, after an instruction to start operation is given to projector 20, control unit 11 instructs projector 20 to lower the dimming rate of lighting fixture LFn to be controlled to less than the second threshold, and in response to this, closes blinds 50. Furthermore, after an instruction to end operation is given to projector 20, control unit 11 instructs projector 20 to raise the dimming rate of lighting fixture LFn to be controlled to exceed the first threshold, and in response to this, opens blinds 50.

[0098] Fig. 9 is a diagram for explaining the flow of the lighting interlocking process. Fig. 10 is a diagram for explaining the relationship between the contact signal and the opening and closing of the blinds 50. The lighting interlocking process will be explained below with reference to Figs. 9 and 10 as well as the output control instruction table 5500 shown in Fig. 6.

[0099] The control unit 11 reads out the target group of the lighting fixture LFn, etc., the dimming rate threshold, etc. (step S201). Specifically, the contact-linked remote control 10 reads out the output control instruction table 5500 shown in FIG. 6 from the storage unit 12.

[0100] 6, the detection setting 532 of the output terminal B1 is the third detection setting. In addition, the output condition 533, which is the criterion for determining whether or not to output a contact signal from the output terminal B1, is that the target group is group 401, the second threshold value of the dimming rate is 20% and the first threshold value of the dimming rate is 50%.

[0101] Next, control unit 11 reads out the dimming rate instructed to the target group (step S203). Control unit 11 reads out the dimming rate instructed to group 401, which is the target group, in the control instruction. When control unit 11 instructs first control content 504, the dimming rate instructed to group 401 by control unit 11 is 10[%].

[0102] Next, the control unit 11 determines whether the dimming rate instructed to the group 401, which is the target group, is lower than the second threshold value (step S205).

[0103] In step S205, if the dimming rate of group 401, which is the target group, is lower than the second threshold value (YES in step S205), control unit 11 outputs a contact signal (step S207, rising edge 161).

[0104] In this case, the second threshold value for the dimming rate is 20% and the dimming rate instructed to group 401 by control unit 11 is 10%, so the dimming rate instructed to group 401, which is the target group, is lower than the second threshold value (YES in step S205). Therefore, control unit 11 outputs a contact signal to close blinds 50 (step S207).

[0105] Thereafter, when the control unit 11 instructs the second control content 506, the dimming rate that the control unit 11 instructs the group 401 to use is 80[%], which is the default lighting condition.

[0106] In step S205, if the dimming rate of group 401, which is the target group, is equal to or higher than the second threshold (NO in step S205), control unit 11 determines whether the dimming rate exceeds the first threshold (step S209).

[0107] In step S209, if the dimming rate exceeds the first threshold value (YES in step S209), control unit 11 outputs a contact signal (step S211, falling edge 163).

[0108] In this case, the first threshold value for the dimming rate is 50% and the dimming rate instructed to group 401 by control unit 11 is 80%, so the dimming rate instructed to group 401, which is the target group, is higher than the first threshold value (YES in step S209). Therefore, control unit 11 outputs a contact signal to open blinds 50 (step S211).

[0109] In step S209, if the dimming rate is equal to or less than the first threshold value (NO in step S209), control unit 11 ends the lighting interlocking process.

[0110] This completes the lighting interlocking process.

[0111] In this embodiment, the operation of the projector 20 can be linked not only to the dimming rate of the lighting fixture LFn but also to the opening and closing of the blinds 50. This helps the user to become immersed in the video and audio while watching video. Furthermore, this embodiment can eliminate the need to manually open and close the blinds 50 in accordance with the dimming rate of the lighting fixture LFn.

[0112] <1.6. Operation check process> In the operation check process, when an operation check button is pressed, the control unit 11 transmits a control instruction or a contact signal regardless of whether a contact signal output device is connected. Specifically, when an operation check button BA1 to BA6 is pressed, the control unit 11 transmits a control instruction corresponding to the operation check button BA1 to BA6 to the wireless communication unit 133. Also, in the operation check process, when an operation check button BB1 to BB6 is pressed, the control unit 11 outputs a contact signal corresponding to the operation check button BB1 to BB6 from the contact output unit 132.

[0113] The operation check buttons BA1 to BA6 are buttons corresponding to the input terminals A1 to A6, respectively. When the operation check buttons BA1 to BA6 are pressed, the control unit 11 outputs a control instruction corresponding to the input terminals A1 to A6 in the input control instruction table 5000.

[0114] Moreover, the operation check buttons BB1 to BB6 are buttons corresponding to the output terminals B1 to B6, respectively. When the operation check buttons BB1 to BB6 are pressed, the control unit 11 causes the output terminals B1 to B6 to output contact signals.

[0115] FIG. 11 is a diagram for explaining the timing of outputting the illumination control signal in the operation check process.

[0116] <1.6.1. When operation check button BA1~6 is pressed> When the detection setting 502 for the input terminals A1 to A6 is the first detection setting, when an operation check button BA1 to BA6 is pressed (turned ON), the control unit 11 outputs the control instruction registered for the input terminals A1 to A6 corresponding to BA1 to BA6. The control instruction is output at the timing when an edge 121 at which the operation check button is pressed (turned ON) is detected. The edge 121 is an edge corresponding to the first identification signal unit 1001.

[0117] 5 is registered in the storage unit 12, and if the count number of the specific signal part when the edge 121 is detected is an odd number, the control unit 11 instructs the first control object 503 to carry out first control content 504. On the other hand, if the count number of the specific signal part when the edge 121 is detected is an even number, the control unit 11 instructs the second control object 505 to carry out second control content 506.

[0118] When the detection setting for the input terminals A1 to A6 is the second detection setting, upon detecting that an operation check button BA1 to BA6 has been pressed (turned OFF), the control unit 11 outputs the control instruction registered in the input terminals A1 to A6 corresponding to BA1 to BA6. The control instruction is output at edge 123 where the operation check button has been pressed (turned OFF). Edge 123 is an edge corresponding to the second specifying signal unit 1002.

[0119] 5 is registered in the storage unit 12, and if the count number of the specific signal part when the edge 123 is detected is an odd number, the control unit 11 instructs the first control object 503 to execute first control content 504. On the other hand, if the count number of the specific signal part when the edge 123 is detected is an even number, the control unit 11 instructs the second control object 505 to execute second control content 506.

[0120] When the detection setting for the input terminals A1 to A6 is the third detection setting, upon detecting that the operation confirmation button has been pressed (turned ON) and that the operation confirmation button has been pressed and then released (turned OFF), the control unit 11 outputs the control instructions registered in the input terminals A1 to A6 corresponding to BA1 to BA6.

[0121] The control instructions are output at edge 125 when the operation confirmation button is pressed (turned ON) and at edge 126 when the operation confirmation button is pressed and then released (turned OFF). Edge 125 and edge 126 are edges corresponding to the third specified signal part 1003.

[0122] When the detection setting for the input terminals A1 to A6 is the fourth detection setting, upon detecting that the operation confirmation button has been pressed (turned OFF) and that the operation confirmation button has been pressed and then released (turned ON), the control unit 11 outputs the control instructions registered in the input terminals A1 to A6 corresponding to BA1 to BA6.

[0123] The control instructions are output at edge 127 when the operation confirmation button is pressed (turned OFF) and at edge 128 when the operation confirmation button is pressed and then released (turned ON). Edge 127 and edge 128 are edges corresponding to the fourth specified signal part 1004.

[0124] <1.7.2. When operation check buttons BB1 to BB6 are pressed>

[0125] When the detection setting for the output terminals B1 to B6 is the first detection setting, upon detecting that any of the operation check buttons BB1 to BB6 has been pressed (turned ON), the control unit 11 outputs a contact signal from the output terminals B1 to B6 corresponding to the operation check buttons BB1 to BB6. The contact signal is output at the edge 121 where the operation check button has been pressed (turned ON).

[0126] When the detection setting for the output terminals B1 to B6 is the second detection setting, upon detecting that an operation check button BB1 to 6 has been pressed (turned OFF), the control unit 11 outputs a contact signal from the output terminal B1 to B6 corresponding to the operation check button BB1 to 6. The contact signal is output at the edge 123 where the operation check button has been pressed (turned OFF).

[0127] When the detection setting for the output terminals B1 to B6 is the third detection setting, upon detecting that an operation check button has been pressed (turned ON) or that an operation check button has been pressed and then released (turned OFF), the control unit 11 outputs a contact signal from the output terminals B1 to B6 corresponding to the operation check buttons BB1 to BB6. The contact signals are output at edge 125 when the operation check button is pressed (turned ON) and at edge 126 when the operation check button is pressed and then released (turned OFF).

[0128] When the detection setting for the output terminals B1 to B6 is the fourth detection setting, upon detecting that an operation check button has been pressed (turned OFF) or that an operation check button has been pressed and then released (turned ON), the control unit 11 outputs a contact signal from the output terminals B1 to B6 corresponding to the operation check buttons BB1 to BB6. The contact signals are output at edge 127 when the operation check button is pressed (turned OFF) and at edge 128 when the operation check button is pressed and then released (turned ON).

[0129] This completes the operation check process.

[0130] In this embodiment, when the operation check button is pressed, the contact-linked remote control 10 outputs a control signal registered to the input terminal corresponding to the operation check button and outputs a contact signal from the output terminal corresponding to the operation check button. Therefore, the contact-linked remote control 10 of this embodiment can easily check the operation of the lighting fixture LFn or the like when a contact signal is output from a contact signal output device such as a projector 20, without connecting the contact signal output device.

[0131] <1.8. Other examples of lighting control processing> In the above embodiment, the contents of row 521 corresponding to input terminal A1 in the control instruction table shown in Fig. 5 have been described. Below, the contents of rows 522 to 526 in Fig. 5 will be described.

[0132] The detection setting at input terminal A2 shown in row 522 is the second detection setting, so when the second specified signal part 1002 is detected at input terminal A2, control unit 11 outputs a control instruction.

[0133] When the control unit 11 detects the second specific signal unit 1002, if the number of detected specific signal units is odd, the control unit 11 transmits a control instruction of first control content 504 to the first control object 503. On the other hand, if the number of detected specific signal units is even, the control unit 11 transmits a control instruction of second control content 506 to the second control object 505.

[0134] The first control content 504 shown in row 522 is lighting with a default color "0101." The default color "0101" is a predetermined color, such as gold. Other default colors include a haze color "1108" and a vacuum color "1101."

[0135] The detection setting for input terminal A3 shown in row 523 is the third detection setting. Therefore, when the third specified signal part 1003 is detected at input terminal A3, control unit 11 outputs a control instruction.

[0136] When third specified signal section 1003 is detected at input terminal A3, if the number of detected specified signal sections is even, control section 11 transmits a control instruction to group 402 of dimming rate: +10[%], fade: 5[s]. Fading refers to gradually changing the dimming rate, etc. If the fade time is 5[s] and the dimming rate is to be increased by 10[%], the dimming rate is linearly increased by 10[%] over 5[s]. When third specified signal section 1003 is detected at input terminal A3, if the output of the counter for input terminal A3 becomes an odd number, the control instruction transmitted to group 402 is dimming rate: -10[%], fade: 5[s].

[0137] The detection setting for input terminal A4 shown in row 524 is the fourth detection setting. Therefore, when the fourth specified signal part 1004 is detected at input terminal A4, the control unit 11 outputs a control instruction.

[0138] If the number of detected specific signal portions when fourth specific signal portion 1004 is detected at input terminal A4 is even, control unit 11 transmits a control instruction to group 402: color temperature: +500 [K], fade: 10 [s]. In this case, control unit 11 issues an instruction to linearly increase the color temperature by 500 [K] over 10 [s].

[0139] If the number of detected specific signal parts when the fourth specific signal part 1004 is detected at input terminal A4 is odd, the control unit 11 sends a control instruction to group 402: color temperature: -500 [K], fade: 10 [s].

[0140] The detection setting for input terminal A5 shown in row 525 is the first detection setting. Therefore, when the first specified signal part 1001 is detected at input terminal A5, control unit 11 outputs a control instruction.

[0141] When first specific signal part 1001 is detected at input terminal A5, if the number of detected specific signal parts is even, control unit 11 transmits a control instruction for scene A. When the control instruction is for a scene, control unit 11 performs control on multiple groups. For example, the control instruction for scene A sets the dimming rate of lighting fixture LFn included in group 401 to 50% and the dimming rate of lighting fixture LFn included in group 402 to 70%.

[0142] When first specifying signal unit 1001 is detected at input terminal A5, if the output of the counter for input terminal A5 becomes an odd number, the control instruction transmitted is scene B. When the content of the control instruction is scene B, control unit 11 sets, for example, the dimming rate of lighting fixture LFn included in group 401 to 20% and the dimming rate of lighting fixture LFn included in group 402 to 40%.

[0143] The detection setting of input terminal A6 shown in row 526 is the second detection setting. Therefore, when the second specified signal part 1002 is detected at input terminal A6, control unit 11 outputs a control instruction.

[0144] If the counter output for input terminal A6 becomes an even number when the second specified signal part 1002 is detected at input terminal A6, control unit 11 does not send a control instruction. On the other hand, if the counter output becomes an odd number when the second specified signal part 1002 is detected at input terminal A6, control unit 11 instructs group 401 to illuminate with the default color "0101".

[0145] <1.9.Effects> As described above, in this embodiment, contact-linked remote control 10 receives a contact signal output from a contact signal output device that links with a lighting fixture such as projector 20. Contact-linked remote control 10 instructs control of the content registered by the user depending on the number of times a specific signal portion in the contact signal is detected. Therefore, lighting fixtures can be controlled according to the content desired by the user depending on the number of times a specific signal portion included in a contact signal output from projector 20 or the like is detected.

[0146] In this embodiment, lighting fixture LFn can be controlled according to the number of times a specific signal part is detected, allowing for a wide variety of control operations even when the number of contact signals that can be received simultaneously is limited.

[0147] In this embodiment, the projector 20 and the lighting fixture LFn can be controlled in conjunction with each other. Therefore, this embodiment can help the user to immerse themselves in the video and audio when watching video. Furthermore, this embodiment can eliminate the need to manually adjust the dimming rate of the lighting fixture LFn in response to the operation of the projector 20.

[0148] In this embodiment, the operation of the projector 20 can be linked not only to the dimming rate of the lighting fixture LFn but also to the opening and closing of the blinds 50. Therefore, this embodiment can more effectively help the user to become immersed in the video and audio while watching video. Furthermore, this embodiment can eliminate the need to manually open and close the blinds 50.

[0149] In this embodiment, when an operation check button is pressed, the contact-linked remote control 10 outputs a control signal registered in the input terminal corresponding to the operation check button, or a contact signal from the output terminal corresponding to the operation check button. Therefore, with the contact-linked remote control 10 of this embodiment, it is possible to easily check the operation of lighting fixtures LFn, etc. when a contact signal is output from the projector 20, etc., without connecting a contact signal output device such as the projector 20. Therefore, even when building a lighting system 40 that controls many lighting fixtures LFn, it is possible to easily check the operation of the lighting system 40 while it is being built. This makes it possible to build the lighting system 40 more efficiently.

[0150] <4. Other variations> (1) Control of lighting fixtures, etc. not included in the plurality of lighting systems 40 In the above embodiment, an example has been described in which the contact-linked remote control 10 controls the lighting fixtures LFn and the blinds 50 included in the lighting system 40. However, the contact-linked remote control 10 may also control lighting fixtures and the like that are not included in the lighting system 40. For example, the contact-linked remote control 10 may control lighting fixtures and the like that are not included in the lighting system 40 and that are located on a different floor from the contact-linked remote control 10.

[0151] This allows for control of lighting fixtures and the like on a larger scale than the lighting system 40.

[0152] (2) Computer-based registration process In the above embodiment, an example has been described in which, in the registration process, the contact-linked remote control 10 receives a registration request output from the tablet 46 and registers the control content included in the registration request in the control instruction table.

[0153] However, the control contents may be registered in the control instruction table using a computer (not shown) connected by wire or wirelessly to the contact-linked remote control 10. The contents of the control instruction table may also be configured so that they can be copied to another contact-linked remote control 10 via a computer connected by wire or wirelessly to the contact-linked remote control 10.

[0154] This can improve the efficiency of setting the contact-linked remote control 10. In particular, it can improve the efficiency of setting the contact-linked remote control 10 in an office or the like that uses the same control instruction table.

[0155] (3) Control of the lighting interlocking device via the wireless communication unit 133 In the above embodiment, an example has been described in which the blinds 50, which are an example of a lighting interlocking device, are controlled by the contact signal output from the contact output unit 132. However, the lighting interlocking device may also be controlled via the wireless communication unit 133.

[0156] This makes it possible to control a number of lighting interlocking devices that exceeds the number of output terminals.

[0157] (4) Changing the reference pulse width In the above embodiment, the reference pulse width Wref is described as having three values: 10 mS, 100 mS, and 1000 mS. However, the minimum pulse width is not limited to these three values ​​and may be longer. Furthermore, the minimum pulse width may be changed to any value depending on the expected noise level, etc.

[0158] This makes it possible to prevent malfunctions even when the contact-linked remote control 10 is used in an environment where large noises may be input.

[0159] (5) Examples of other devices that can be linked with the lighting control device In the above embodiment, an example has been described in which the contact signal output device is the projector 20. However, the contact signal output device may be another device such as a music playback device.

[0160] For example, if the contact signal output device is a karaoke machine, which is an example of a music playback device, the karaoke machine outputs a contact signal when the karaoke song starts to be played, thereby changing the lighting conditions from the default conditions to the karaoke lighting conditions. Also, the karaoke machine outputs a contact signal when the karaoke song ends to return the lighting conditions to the default conditions.

[0161] For example, if the contact signal output device is a background music playback device for a commercial facility, which is an example of a music playback device, the background music playback device for the commercial facility starts playing background music when the commercial facility opens, and further outputs a contact signal to change the lighting conditions from the lighting conditions when the facility is closed to the lighting conditions when the facility is open.

[0162] In addition, the background music playback device for commercial facilities plays "Hotaru no Hikari" or "Wakare no Waltz" as background music before the commercial facility closes, stops playing the background music when the commercial facility closes, and outputs a contact signal to change the lighting conditions from the lighting conditions during business hours to the lighting conditions during closing hours.

[0163] (6) Disable input terminals A1 to A6 and output terminals B1 to B6 In the above embodiment, it has been explained that all of the input terminals A1 to A6 are capable of receiving contact signals, and all of the output terminals B1 to B6 are capable of outputting contact signals.

[0164] However, it is also possible to set some input terminals to be disabled so that they cannot receive contact signals, or to set some output terminals to be disabled so that they cannot transmit contact signals.

[0165] By disabling unused input terminals or unused output terminals, it is possible to prevent malfunctions of lighting fixtures LFn, etc. Note that the indicators LA1-6 and LB1-6 corresponding to disabled input terminals A1-A6 and output terminals B1-B6 do not flash but remain off.

[0166] (7) Retransmission of control instructions In the above embodiment, an example has been described in which the contact-linked remote control 10 does not check whether the gateway 45 has received the control instruction after transmitting the control instruction to the gateway 45. However, if the gateway 45 receives the control instruction, the gateway 45 may notify the contact-linked remote control 10 that the control instruction has been received.

[0167] This allows the contact-linked remote control 10 to check whether the control instruction has reached the gateway 45. Furthermore, if the control instruction has not reached the gateway 45, the contact-linked remote control 10 can reliably control the lighting fixture LFn that is the control target by resending the control instruction.
