  In the present embodiment, there are the following four modes for the operation (dimming output control) of the lighting control device 100 to dimm the lighting fixture 60.

  (1) Color temperature control mode: In a state where the ports 610 and 620 (first terminal and second terminal) of the signal terminal block 13 are connected to one (or one group) of lighting fixtures 60 (third lighting fixtures). Used. The brightness (output) and color temperature of the lighting fixture 60 are controlled by controlling the white LED (first light source) and the light bulb color LED (second light source) of the lighting fixture 60 using the outputs of the ports 610 and 620. To do. In the color temperature control mode, the user can switch between automatic operation and manual operation using the portable terminal 71 or the remote control device 80. When the automatic operation is set, the lighting control device 100 adjusts the white LED and the light bulb color LED of the lighting fixture 60 according to the target brightness (target output) and the target color temperature of the lighting fixture 60 set automatically. Shine. On the other hand, when the manual operation is set, the lighting control device 100 adjusts the lighting fixture 60 according to the target brightness and target color temperature of the lighting fixture 60 set by the user using the portable terminal 71, the remote control device 80, the wall switch, and the like. Dimming white LED and light bulb color LED.

  (2) Balance control mode: The port 610 (first terminal) of the signal terminal block 13 is connected to one (or one group) of lighting fixtures 60 (first lighting fixtures), and the port 620 (second terminal) is separate. It is used in a state of being connected to one (or one group) of lighting fixtures 60 (second lighting fixtures). Appropriate illuminance maintenance control (daylight use control) is performed in which the outputs of the ports 610 and 620 operate following the sensor voltage of the illuminance sensor 300. As an additional function, balance control is performed to control the output of the port 620 at a specified ratio of the output of the port 610. The default setting ratio is 100% (output of port 610 = output of port 620). Even in the balance control mode, the user can switch between automatic operation and manual operation using the portable terminal 71 or the remote control device 80. When the automatic operation is set, the lighting control device 100 operates in the balance control mode. When the manual operation is set, the lighting control device 100 stops the operation in the balance control mode, and the target brightness of each lighting fixture 60 set by the user using the portable terminal 71, the remote control device 80, the wall switch, or the like ( Each lighting fixture 60 is dimmed at the target output. The illumination control device 100 maintains the current dimming rate until the target brightness is set after the manual operation is switched to the automatic operation.

  (3) Daylight sensor control mode: Similarly to the balance control mode, the port 610 (first terminal) of the signal terminal block 13 is connected to one (or one group) of lighting fixtures 60 (first lighting fixture), The port 620 (second terminal) is used in a state where it is connected to another (or group of) lighting fixtures 60 (second lighting fixtures). The output of the ports 610 and 620 is controlled according to the daylight quantity. At the start of the operation in the daylight sensor control mode, each lighting fixture 60 is dimmed at a preset common dimming rate. Thereafter, the change in daylight intensity was monitored from the sensor voltage of the illuminance sensor 300, and an increase corresponding to the daylight control amount (daylight intensity for reducing the dimming rate by 1%) preset for the output of the port 610 occurred. In this case, the lighting fixture 60 at the output destination of the port 610 is dimmed at a dimming rate 1% lower than the current state. Similarly, when an increase of a daylight control amount (daylight amount for reducing the dimming rate by 1%) set in advance for the output of the port 620 occurs, the port 620 has a dimming rate 1% lower than the current level. The lighting fixture 60 of the output destination is dimmed. Even in the daylight sensor control mode, the user can switch between automatic operation and manual operation using the portable terminal 71 or the remote control device 80. When the automatic operation is set, the illumination control device 100 operates in the daylight sensor control mode. When the manual operation is set, the lighting control device 100 stops the operation in the daylight sensor control mode, and the target brightness of each lighting fixture 60 set by the user using the portable terminal 71, the remote control device 80, the wall switch, or the like. The light fixtures 60 are dimmed with the current (target output). The illumination control device 100 maintains the current dimming rate until the target brightness is set after the manual operation is switched to the automatic operation.

  (4) Individual control mode: Similarly to the balance control mode and the daylight sensor control mode, the port 610 (first terminal) of the signal terminal block 13 is one (or one group) lighting fixture 60 (first lighting fixture). And the port 620 (second terminal) is used in a state where it is connected to another lighting device 60 (second lighting device). For the lighting device 60 that is the output destination of the port 610, the user can switch between constant illumination control, timer control, and constant dimming rate control using the portable terminal 71 or the remote control device 80. When the illuminance constant control is set, the lighting control device 100 monitors the change in daylight quantity from the sensor voltage of the illuminance sensor 300 and adjusts the lighting fixture 60 that is the output destination of the port 610 so that the illuminance is constant. . When the timer control is set, the lighting control device 100 dimmes the lighting fixture 60 that is the output destination of the port 610 with the dimming rate corrected according to the cumulative operation time. That is, the illumination control device 100 performs initial illuminance correction. When the dimming rate constant control is set, the lighting control device 100 dims the lighting fixture 60 that is the output destination of the port 610 at a preset dimming rate. The user can switch between the timer control and the constant dimming rate control using the portable terminal 71 or the remote control device 80 for the lighting fixture 60 that is the output destination of the port 620. Even in the individual control mode, the user can switch between automatic operation and manual operation using the portable terminal 71 or the remote control device 80. When the automatic operation is set, the lighting control device 100 operates in the individual control mode. When the manual operation is set, the lighting control device 100 stops the operation in the individual control mode, and the target brightness of each lighting fixture 60 set by the user using the portable terminal 71, the remote control device 80, the wall switch, or the like ( Each lighting fixture 60 is dimmed at the target output. The illumination control device 100 maintains the current dimming rate until the target brightness is set after the manual operation is switched to the automatic operation.

In addition, the calculation unit 120 adjusts the lighting fixture 60 installed in the control area 2 at a constant rate of change with respect to the change in the dimming rate of the lighting fixture 60 installed in the control area 1. Calculate the light rate. This ratio is set in advance and is stored in the storage unit 150 of the illumination control apparatus 100. For example, as shown in FIG. 9, the current dimming rate of the lighting fixtures 60 installed in the control area 1 and the control area 2 (before change) is 70%, and the current lighting fixture 60 installed in the control area 1 If the dimming rate suitable for the illuminance is 30% and the ratio stored in the storage unit 150 is 25%, the calculation unit 120 controls the dimming rate 30% of the lighting fixture 60 installed in the control area 1. The dimming rate 60% (= 70% − ((70% −30%) × 0.25)) of the lighting fixture 60 installed in the area 2 is calculated.

  In step S123 of FIG. 7, the control unit 130 performs PWM for dimming the luminaire 60 installed in the control area 1 at the dimming rate calculated in step S122 for the luminaire 60 installed in the control area 1. A signal (dimming signal) is generated and output from the port 610. Further, the control unit 130 adjusts the PWM signal (the dimming signal) for dimming the luminaire 60 installed in the control area 2 at the dimming rate calculated in step S112 for the luminaire 60 installed in the control area 2. ) And output from the port 620. Thereby, the control unit 130 controls the output of the lighting fixture 60 installed in the control area 1 and the lighting fixture 60 installed in the control area 2. That is, the control unit 130 dimmes the lighting fixture 60 installed in the control area 1 and the lighting fixture 60 installed in the control area 2.

  The above operation is repeated while the balance control mode is selected.

  In the balance control mode, as described above, the control unit 130 changes the dimming rate of the lighting fixture 60 installed in the control area 1 according to the illuminance of the control area 1 and is installed in the control area 1. The dimming rate of the lighting fixture 60 installed in the control area 2 is changed at a constant rate of change with respect to the change amount of the dimming rate of the lighting fixture 60. For this reason, the lighting fixture 60 installed in the control area 2 can be appropriately dimmed only by measuring the illuminance of the control area 1.

  Compared with the control area 1 near the window, in the control area 2 far from the window, the influence of the amount of external light on the illuminance is considered to be small, so the ratio stored in the storage unit 150 is set lower than 100%. It is desirable.

  It is desirable that the ratio stored in the storage unit 150 can be set from the outside. For example, the input unit 110 inputs a ratio setting stored in the storage unit 150 from the portable terminal 71 or the remote control device 80 via the wired transmission / reception circuit 700 or the wireless transmission / reception circuit 800.

  It is desirable to set an upper limit value for the dimming rate. For example, when the dimming rate of the luminaire 60 installed in the control area 1 has reached a preset upper limit value, the control unit 130 may decrease the illuminance measurement value input through the input unit 110. Suppose that the dimming rate of the lighting fixture 60 installed in the control area 1 is not changed.

  In addition, the operation | movement demonstrated here is a thing when automatic driving | operation is set. When manual operation is set, in step S121, the target output (for example, 50%) of the luminaire 60 is input, and in step S122, the dimming rate (for example, 50%) corresponding to the input target output. Calculated.

  In the example described here, the second area is only the control area 2, but a plurality of second areas may exist. When there are a plurality of second areas, it is desirable that the ratio stored in the storage unit 150 is set individually for each of the second areas. This ratio is more desirably set lower as the second region is farther from the window. For example, in the example of FIG. 7, it is assumed that the control area 1, the control area 2, the control area 3, and the control area 4 exist in the order closer to the window. In this case, the signal terminal block 13 is provided with two ports for the control area 3 and the control area 4 in addition to the ports 610 and 620. The ratios stored in the storage unit 150 are, for example, 75% for the control area 2, 50% for the control area 3, and 25% for the control area 4.

  FIG. 10 is a flowchart showing the operation of the illumination control apparatus 100 when the daylight sensor control mode is selected in the example of FIG.

  It is assumed that the user selects the daylight sensor control mode on the screen of the portable terminal 71 (external device). In this case, the portable terminal 71 transmits a signal instructing setting of the daylight sensor control mode to the controller 10 via the wireless LAN adapter 70 as a daylight sensor control mode setting signal. Alternatively, it is assumed that the user selects the daylight sensor control mode on the screen of the remote control device 80 (external device). In this case, the remote control device 80 transmits a daylight sensor control mode setting signal to the controller 10.

  The input unit 110 of the illumination control device 100 inputs a daylight sensor control mode setting signal from the portable terminal 71 or the remote control device 80 via the wired transmission / reception circuit 700 or the wireless transmission / reception circuit 800. The control unit 130 of the illumination control device 100 starts the daylight sensor control mode process according to the input daylight sensor control mode setting signal.

  In the daylight sensor control mode, the lighting control device 100 can be a base light, a downlight, a ceiling light, or these lights installed in a room where external light enters from an opening (for example, a window or a glass door). This is useful when dimming both a group of lighting fixtures 60 (first lighting fixture) that is a combination and another group of lighting fixtures 60 (second lighting fixtures) that are mainly spotlights. Here, as one example, the controller 10 (at least the illuminance sensor 300) is installed near the window of a room, and a base light (first lighting fixture) connected to the port 610 and a port 620 are installed in the room. Assume that a connected spotlight is installed.

  In the storage unit 150 of the illumination control apparatus 100, as a condition for changing the dimming rate of the base light by a certain amount (for example, 1%), a change amount (for example, 100 lx) of illuminance in the room is used as the first change amount. It is remembered. In addition, the storage unit 150 stores a change amount (for example, 1000 lx) of illuminance in the room as a second change amount as a condition for changing the dimming rate of the spotlight by a certain amount (for example, 1%). Yes.

  In step S <b> 131 of FIG. 10, the input unit 110 inputs a measured value of illuminance in the control area 1 from the illuminance sensor 300 installed in the control area 1.

  In step S132 of FIG. 10, the control unit 130 determines whether or not the measurement value of illuminance input in step S131 has changed the first change amount stored in the storage unit 150 as compared to the initial illuminance. If it is determined that the change has occurred even once, the control unit 130 thereafter compares the illuminance measurement value input in step S131 with the illuminance when it is determined that the first change amount has changed last time. It is determined whether or not one change amount has changed. For example, if the initial illuminance is 1000 lx and the first change amount is 100 lx, the control unit 130 first determines that the first change amount has changed when the illuminance increases to 1100 lx, and then the illuminance increases to 1200 lx. Or when it has decreased to 1000 lx, it is determined that the first change amount has changed. The control unit 130 first determines that the first change amount has changed even when the illuminance decreases to 900 lx, and then changes the first change amount when the illuminance increases to 1000 lx or decreases to 800 lx. Is determined. If it is determined that the first change amount has changed, the process proceeds to step S133. If it is determined that the first change amount has not changed, the process proceeds to step S134.

  In step S133 of FIG. 10, the calculation unit 120 of the lighting control device 100 calculates a dimming rate that is changed by a certain amount for the base light. For example, it is determined that the current dimming rate of the base light (before change) is 70%, the initial illuminance or the illuminance when it is determined that the first change in the previous time has changed is 1000 lx, and the illuminance is increased by 100 lx in step S132. Then, the calculation unit 120 calculates a baselight dimming rate of 69% (= 70% -1%).

  In step S134 of FIG. 10, the control unit 130 determines whether or not the measurement value of the illuminance input in step S131 has changed the second change amount stored in the storage unit 150 as compared with the initial illuminance. If it is determined that the change has occurred even once, the control unit 130 thereafter compares the illuminance measurement value input in step S131 with the illuminance when it is determined that the second change amount has changed last time. 2. Determine whether the amount of change has changed. If it is determined that the second change amount has changed, the process proceeds to step S135. If it is determined that the second change amount has not changed, the process proceeds to step S136.

  In step S135 in FIG. 10, the calculation unit 120 calculates a dimming rate that is changed by a certain amount for the spotlight.

  In step S136 of FIG. 10, the control unit 130 dims the base light at the dimming rate calculated in step S133 (or maintains the previous dimming rate if the current dimming rate is not calculated). PWM signal (dimming signal) is generated and output from the port 610. Further, the control unit 130 adjusts the PWM signal (dimming) for dimming the spotlight at the dimming rate calculated in step S135 (maintaining the previous dimming rate if the current dimming rate is not calculated). Optical signal) is generated and output from the port 620. Thereby, the control part 130 controls the output of a base light and a spotlight. That is, the control unit 130 adjusts the base light and the spotlight.

  The above operation is repeated while the daylight sensor control mode is selected.

  In the daylight sensor control mode, as described above, every time the illuminance of the room changes by the first change amount, the control unit 130 changes the dimming rate of the base light by a certain amount, and the illuminance of the room changes by the second change amount. Each time it changes, the light control rate of the spotlight is changed by a certain amount. For this reason, it becomes possible not only to match the amount of external light but also to dimm the lighting fixture 60 in accordance with the use of the lighting fixture 60.

  Compared with a base light for illuminating a room as a whole, a spot light for illuminating a specific object is considered to have little need to be dimmed according to the illuminance of the room. The first change amount is preferably set to be smaller than the second change amount stored in the storage unit 150. Alternatively, it is desirable that the control unit 130 does not store the second change amount in the storage unit 150 and fixes the light control rate of the spotlight.

  It is desirable that the first change amount and the second change amount stored in the storage unit 150 can be set from the outside. For example, the input unit 110 inputs the setting of the first change amount and the second change amount stored in the storage unit 150 from the portable terminal 71 or the remote control device 80 via the wired transmission / reception circuit 700 or the wireless transmission / reception circuit 800. It shall be.

  It is desirable to set an upper limit value for the dimming rate. For example, when the dimming rate of the lighting fixture 60 has reached a preset upper limit value, the control unit 130 controls the lighting fixture 60 even if the measured illuminance value input by the input unit 110 decreases. The rate shall not be changed.

  The base light may be replaced with a lighting fixture 60 installed in a large room, and the spotlight may be replaced with a lighting fixture 60 installed in a small room (for example, a toilet).

  In addition, the operation | movement demonstrated here is a thing when automatic driving | operation is set. When manual operation is set, in step S131, the target output (for example, 50%) of the lighting fixture 60 is input, and in steps S132 to S135, the dimming rate (for example, 50%) corresponding to the input target output. ) Is calculated.

  Here, a method for setting the initial illuminance will be described.

  When setting the initial illuminance, first, the illuminance sensor 300 is provided with a partition or the luminaire 60 is turned off so that artificial light (light from the luminaire 60) does not enter the illuminance sensor 300. The illuminance is measured using the illuminance sensor 300 in the time zone when daylight (external light) enters. Thereby, the voltage (for example, 2V) corresponding to the measured value of illuminance is output from the illuminance sensor 300. At this time, the illuminance is measured using the illuminance measuring instrument in a state where artificial light does not enter the illuminance measuring instrument separately. Thereby, the measured value (for example, 500 lx) of illuminance is obtained from the illuminance measuring instrument.

  Next, using the portable terminal 71 or the remote control device 80, the measured value of illuminance obtained from the illuminance measuring device is input to the illumination control device 100, and the gain of the illuminance sensor 300 is adjusted (for example, 1.5V Adjust so that the voltage is output). Then, an initial illuminance (for example, 1000 lx) is set (by adjusting the gain, the initial illuminance can be made to correspond to 1.5 V / 500 lx × 1000 lx = 3 V).

  By dimming the lighting fixture 60 in accordance with the change in illuminance from the initial illuminance set as described above (for example, when the external light becomes bright, the dimming rate is lower than 70%), an energy saving effect Can be obtained.

  When the daylight sensor control mode is used, not only when setting the initial illuminance, but always thereafter (that is, when the illumination control system 900 is actually used), the illuminance sensor 300 has artificial light (the luminaire 60). It is desirable to prevent light from entering. As described above, if the controller 10 (at least the illuminance sensor 300) is installed near the window of the room, the illuminance sensor 300 can be provided without providing a partition to the illuminance sensor 300 or turning off the lighting fixture 60. It is thought that the amount of artificial light that enters can be reduced. Unless the lighting fixture 60 is installed around the controller 10 (at least the illuminance sensor 300), the amount of artificial light entering the illuminance sensor 300 can be further reduced.

  As described above, the illuminance sensor 300 is installed at a place where only daylight is measured (for example, at a window or in a place separated from the lighting device 60 such as a small room). Whenever the first change amount is changed, the dimming rate of the base light is changed by a certain amount. When the measured value of illuminance obtained from the illuminance sensor 300 is changed by the second change amount, the dimming rate of the spotlight is changed by a certain amount. By changing it, it is possible to detect the amount of external light, not the illuminance on the floor or work surface, and to control the luminaire 60 accordingly. For this reason, even if it is a case where the illumination intensity of a floor surface or a work surface, such as a high ceiling, cannot be detected correctly, the lighting fixture 60 can be appropriately dimmed.

  Instead of the first change amount and the second change amount, a change rate of the dimming rate with respect to the daylight amount (measured value of illuminance obtained from the illuminance sensor 300) may be set. In this case, the storage unit 150 stores the change rate of the dimming rate of the baselight with respect to the daylight amount as the first change rate, and stores the change rate of the dimming rate of the spotlight with respect to the daylight amount as the second change rate. The As shown in FIG. 26, the control unit 130 performs the base light with the dimming rate (output 2 in FIG. 26) changed at the first change rate according to the daylight amount (measured value of illuminance obtained from the illuminance sensor 300). A PWM signal (dimming signal) for dimming is generated and output from the port 610. In addition, the control unit 130 dims the spotlight with the dimming rate (output 1 in FIG. 26) changed at the second change rate according to the daylight amount (measured value of illuminance obtained from the illuminance sensor 300). PWM signal (dimming signal) is generated and output from the port 620. That is, the control unit 130 controls the output 1 and the output 2 according to the daylight amount. Thereby, it is possible to detect the amount of external light, not the illuminance on the floor or work surface, and control the lighting fixture 60 accordingly.

  When the user selects the individual control mode on the screen of the portable terminal 71 (external device) or when the user selects the individual control mode on the screen of the remote control device 80 (external device), the lighting control device 100 The input unit 110, the calculation unit 120, and the control unit 130 perform processing according to the individual control mode, as in the other modes. The timer unit 140 of the illumination control device 100 measures the accumulated operation time used when timer control is set.

  As described above, in the present embodiment, the control unit 130 of the lighting control device 100 controls the dimming signal when the first lighting fixture is connected to the port 610 and the second lighting fixture is connected to the port 620. Is output from each of the ports 610 and 620, so that the first lighting device and the second lighting device can be dimmed individually. In addition, the control unit 130 outputs a dimming signal from each of the ports 610 and 620 when the third lighting fixture to which the first light source and the second light source are attached is connected to both the ports 610 and 620. Thus, the first light source and the second light source can be individually dimmed. That is, in the present embodiment, the ports 610 and 620 can be used both for the purpose of individually dimming different lighting fixtures 60 and for the purpose of dimming different light sources of the same lighting fixture 60 individually. .

Embodiment 2. FIG.
In the present embodiment, differences from the first embodiment will be mainly described.
The configuration of the controller 10 according to the present embodiment is the same as that of the first embodiment shown in FIG.

The lighting control device 100 operates in the color temperature control mode when, for example, the user designates the color temperature and brightness desired to be realized in the lighting fixture 60. The user designates the color temperature and brightness using the remote control device 80 or the portable terminal 71.
In the following description, the designated color temperature is set as the target color temperature, and the designated brightness is set as the target output.

  First, the controller 10 when the illumination control apparatus 100 operates in the color temperature control mode will be described. It is assumed that there are lighting fixtures 60 to which a white LED (first light source) is connected and a lighting bulb color LED (second light source) is connected. For example, a lighting device 60 of a white LED (first light source) is connected to the port 610 (output 1), and a lighting device 60 of a light bulb color LED (second light source) is connected to the port 620 (output 2). To do.

The color temperature of the white LED and the light bulb color LED is different. For example, the color temperature of the white LED is 5000K, and the color temperature of the light bulb color LED is 3000K.
Further, it is assumed that the white LED and the light bulb color LED have different light fluxes at the same output time. For example, the luminous flux of the white LED at 100% output (at the maximum output) is 2940 lm, and the luminous flux of the light bulb color LED at 100% output is 2380 lm. In the following, the luminous flux at 100% output is defined as the maximum luminous flux.

The range of the target color temperature that can be specified by the user is, for example, 3,000K to 5,000K. However, the range of the target color temperature is not limited to the above range, and may be, for example, 2,700K to 6,500K or other ranges.
The target output range that can be specified by the user is 0% to 100%. However, the range of the target output is not limited to the above range, and may be, for example, 10% to 90% or other range.

  Next, the operation of the illumination control device 100 in the color temperature control mode will be described.

The storage unit 150 of the illumination control device 100 includes a parameter storage unit 1521.
Parameters required for control processing (color temperature variable control processing) for changing the color temperature are set in the parameter storage unit 1521.

FIG. 11 is a diagram showing a configuration of the parameter storage unit 1521 according to the present embodiment.
As shown in FIG. 11, the parameter storage unit 1521 includes (1) the color temperature K1 (first color temperature) of the white LED, (2) the color temperature K2 (second color temperature) of the light bulb color LED, (3) Target color temperature K3 (realized color temperature), (4) white LED maximum luminous flux L1 (first maximum luminous flux), (5) bulb color LED maximum luminous flux L2 (second maximum luminous flux), (6) appliance maximum luminous flux Value L3, (7) Target output D3, (8) White LED dimming rate D1 (first dimming rate), (9) Light bulb color LED dimming rate D2 (second dimming rate) are set. .

(1) The color temperature K1 of the white LED is set from the outside using an external device (for example, the remote control device 80 or the portable terminal 71). (2) The color temperature K2 of the light bulb color LED is set from the outside using an external device (for example, the remote control device 80 or the portable terminal 71).
Here, it is assumed that the color temperature K1 of the white LED is set to 5000K, and the color temperature K2 of the light bulb color LED is set to 3000K.
If the lighting fixture 60 to be connected is different, the color temperature of the white LED and the light bulb color LED may be different. Therefore, (1) the color temperature K1 of the white LED and (2) the color temperature K2 of the light bulb color LED can be set from the outside.

  (3) The target color temperature K3 is designated by the user using the remote control device 80 or the portable terminal 71. The range of the target color temperature that can be specified is 3,000K to 5,000K. Here, it is assumed that 4000K is specified.

(4) The maximum luminous flux L1 of the white LED is set from the outside using an external device (for example, the remote control device 80 or the portable terminal 71). (5) The maximum luminous flux L2 of the light bulb color LED is set from the outside using an external device (for example, the remote control device 80 or the portable terminal 71).
Here, it is assumed that the maximum luminous flux L1 of the white LED is set to 2940 lm, and the maximum luminous flux L2 of the light bulb color LED is set to 2380 lm.
Since the luminous flux of the LED is an actual value, the brightness of the LED is different even at 100% output. Therefore, if the connected lighting fixtures and LEDs are different, the maximum luminous fluxes of the white LED and the light bulb color LED are also different. Therefore, the maximum luminous flux corresponding to the connected lighting fixture is set from the outside.

  As described above, (1) the color temperature K1 of the white LED, (2) the color temperature K2 of the light bulb color LED, (4) the maximum light flux L1 of the white LED, and (5) the maximum light flux L2 of the light bulb color LED are: It can be set from the outside.

Here, the operation of the controller 10 when setting values (1), (2), (4), and (5) from the outside will be described.
Color temperature value setting that is a request by a user to set a value to (1) the color temperature K1 of the white LED and (2) the color temperature K2 of the light bulb color LED by using the remote control device 80 or the portable terminal 71 from the outside. A request is sent.
When the remote control device 80 is used, the wireless transmission / reception circuit 800 receives a color temperature value setting request from the remote control device 80 (such as a remote controller) and transmits it to the illumination control device 100.
When the portable terminal 71 is used, the wired transmission / reception circuit 700 receives the color temperature value setting request from the portable terminal 71 via the wireless LAN adapter 70 and transmits it to the illumination control device 100.
The input unit 110 of the illumination control apparatus 100 inputs a color temperature value setting request and outputs it to the storage unit 150.
Based on the color temperature value setting request input from the input unit 110, the storage unit 150 sets a value to (1) the color temperature K1 of the white LED or (2) the color temperature K2 of the light bulb color LED.

Further, the user uses the remote control device 80 or the portable terminal 71 from the outside to use (4) the maximum luminous flux L1 of the white LED and (5) the luminous flux value that is a request to set a value to the maximum luminous flux L2 of the bulb color LED. A setup request is sent.
The wireless transmission / reception circuit 800 receives the light flux value setting request from the remote control device 80 and transmits it to the illumination control device 100.
The wired transmission / reception circuit 700 receives the light flux value setting request from the portable terminal 71 via the wireless LAN adapter 70 and transmits it to the illumination control device 100.
The input unit 110 of the illumination control apparatus 100 inputs a light beam value setting request and outputs it to the storage unit 150.
Based on the luminous flux value setting request input from the input unit 110, the storage unit 150 sets values for (4) the maximum luminous flux L1 of the white LED and (5) the maximum luminous flux L2 of the light bulb color LED.

  (6) The higher value of the maximum luminous flux L1 of the white LED and the maximum luminous flux L2 of the light bulb color LED is set as the appliance maximum luminous flux value L3. Accordingly, here, 2940 lm is set as the instrument maximum luminous flux value L3.

(7) The target output designated by the user using the remote control device 80 or the portable terminal 71 is set as the target output D3.
The target output range that can be specified is 0% to 100%. Here, it is assumed that 50% is specified. However, the range of the target output is not limited to the above range.

(8) For the dimming rate D1 of the white LED and (9) the dimming rate D2 of the light bulb color LED, the color temperature of the lighting fixture 60 becomes the target color temperature K3, and the output (brightness) of the lighting fixture 60 is the target output. The dimming rate D1 of the white LED and the dimming rate D2 of the light bulb color LED for setting to D3 are set.
The calculation unit 120 of the illumination control apparatus 100 uses the values of (1) to (7) set in the parameter storage unit 1521 to process the dimming rate D1 of the white LED and the dimming rate D2 of the light bulb color LED. The calculated values are set to (8) the dimming rate D1 of the white LED and (9) the dimming rate D2 of the light bulb color LED.

FIG. 12 is a flowchart of color temperature variable control processing by the illumination control apparatus 100 according to the present embodiment.
In S201, the input unit 110 inputs the target color temperature K3 and the target output D3, and sets the target color temperature K3 and the target output D3 in the parameter storage unit 1521.

  In S202, the calculation unit 120 calculates solutions D1 and D2 that satisfy the following simultaneous equations (Equation 1) and (Equation 2) using the setting values of (1) to (7) in the parameter storage unit 1521 by the processing device. To do.

(Expression 1) L1 × D1 + L2 × D2 = L3 × D3
(Expression 2) (L1 / L3) × D1 × (K3−K1) = (L2 / L3) × D2 × (K2−K3)
When (Expression 2) is modified, the following expression is obtained.
D1 = (L2 * D2 * (K2-K3)) / (L1 * (K3-K1)) = (L2 / L1) * ((D2 * (K2-K3)) / (K3-K1))
When (Expression 2) is modified, the following expression is obtained.
D1 * (K3-K1) = (L2 / L1) * D2 * (K2-K3)

  (Equation 1) is an equation for the luminous flux of the luminaire. In (Expression 1), L1 × D1 is the luminous flux of the white LED, and L2 × D2 is the luminous flux of the light bulb color LED. A luminous flux obtained by adding the luminous flux of the white LED and the luminous flux of the light bulb color LED becomes the luminous flux value of the lighting fixture. Therefore, in (Formula 1), the luminous flux value of the lighting fixture is obtained by multiplying the fixture maximum luminous flux value L3 by the target output D3.

  (Equation 2) is an equation for the color temperature of the luminaire. As shown in the modified formula of (Formula 2), in (Formula 2), the ratio (L2 / L1) of the maximum luminous flux L1 of the white LED and the maximum luminous flux L2 of the bulb color LED is used to determine the color temperature of the lighting fixture. Is represented more accurately.

  The calculation unit 120 sets the calculated D1 and D2 in (8) to (9) of the parameter storage unit 1521.

This will be described using a specific example.
When the values of (1) to (7) in FIG. 11 are substituted into the simultaneous equations (Expression 1) and (Expression 2), the following simultaneous equations (Expression 1) and (Expression 2) are obtained.
(Formula 1) 2940 × D1 + 2380 × D2 = 2940 × 0.5
(Formula 2) (2940/2940) × D1 × (4000−5000) = (2380/2940) × D2 × (3000-4000)
The solutions of the simultaneous equations (Equation 1) and (Equation 2) are D1 = 0.25 and D2 = 0.3.
The calculation unit 120 sets the calculated D1 = 0.25 and D2 = 0.3 in (8) to (9) of the parameter storage unit 1521.
That is, the calculation unit 120 calculates the dimming rate D1 of the white LED as 25% and the dimming rate D2 of the light bulb color LED as 30%.

In S203, the control unit 130 generates a control signal that sets the white LED to the dimming rate D1 and the light bulb color LED to the dimming rate D2 based on the values of (8) to (9) of the parameter storage unit 1521. . In the specific example, the control unit 130 generates a control signal that sets the dimming rate D1 of the white LED to 25% and sets the dimming rate D2 of the light bulb color LED to 30%. The control unit 130 outputs the generated control signal to the PWM amplifier circuit 600.
Above, the color temperature variable control process of the illumination control apparatus 100 is complete | finished.

The PWM amplifier circuit 600 (dimming circuit) generates a PWM signal (dimming signal) based on the input control signal and transmits the PWM signal to the lighting fixture 60.
The white LED of the luminaire 60 is dimmed to a dimming rate D1 (25%), and the light bulb color LED is dimmed to a dimming rate D2 (30%). As a result, the lighting device 60 has the color temperature of the target color temperature K3 (4000K) and the brightness (light flux) (1470 lm) according to the target output D3 (50%).

  Next, an example of how to obtain the appliance maximum luminous flux value L3 when the target color temperature K3 is controlled to 4000K will be described using a specific example.

(1) to (5) in FIG. 11 are substituted into (Expression 2).
(Formula 2) 2940 × D1 × (4000−5000) = 2380 × D2 × (3000-4000)
Here, since the target output D3 is 50%, the dimming rate D1 of the white LED is set to 50%, and D2 is calculated using (Expression 2).
D2 = 2940 * 0.5 * (4000-5000) / 2380 * (3000-4000) = 0.618
In the case of controlling the target color temperature K3 to 4000K, if the dimming rate D1 of the white LED is 50%, the dimming rate D2 of the light bulb color LED is 61.8%.

The luminous flux L ′ of the luminaire 60 when the dimming rate D1 of the white LED is 50% and the dimming rate D2 of the light bulb color LED is 61.8% is calculated.
L ′ = L1 × D1 + L2 × D2 = 2940 × 0.5 + 2380 × 0.618 = 2940 (lm)
This value is equivalent to the maximum luminous flux L3 (2940 lm) when only the white LED is lit at 100% output. L ′ calculated in this way may be set as the maximum luminous flux value L3 when the lighting fixture 60 is controlled to 4000K.

  The fixture maximum luminous flux value L3 is, for example, the luminous flux of the lighting fixture 60 realized when the target output D3 is 100%, and may be set by a setting method other than the above.

  Usually, in a luminaire, brightness (light flux) increases or decreases according to a target output. That is, when the target output is 50%, the brightness (light flux) is also about 50%. However, when the lighting fixture includes a white LED and a light bulb color LED, the maximum light flux (light flux at 100% output) may be different between the white LED and the light bulb color LED. If the maximum luminous flux (luminous flux at 100% output) differs between the white LED and the light bulb color LED, the target color temperature and target output specified by the user may not be realized accurately.

  However, the controller 10 according to the present embodiment takes into consideration the difference in luminous flux between the white LED and the bulb color LED, and uses the ratio of the maximum luminous flux between the white LED and the bulb color LED to determine the white LED and bulb color. Since the dimming rates D1 and D2 with the LED are calculated, the target color temperature and target output specified by the user can be realized accurately.

  In the present embodiment, the color temperature K1 of the white LED, the color temperature K2 of the light bulb color LED, the maximum light flux L1 of the white LED, and the maximum light flux L2 of the light bulb color LED can be set from the outside. Even when a lighting fixture is replaced due to a broken lighting fixture, the color temperature and maximum luminous flux can be set from the outside according to the lighting fixture after replacement. Temperature and target output can be realized.

Embodiment 3 FIG.
The difference between the present embodiment and the first and second embodiments will be mainly described.
The configuration of the controller 10 according to the present embodiment is the same as that of the first embodiment shown in FIG.

The lighting control device 100 executes schedule control for the lighting fixture 60 when the user instructs execution of the schedule using the remote control device 80, the portable terminal 71, and the like.
In the present embodiment, a schedule control method executed by the lighting control device 100 will be described.

In the controller 10 according to the present embodiment, a schedule can be set for the lighting fixture 60, the illuminance sensor 300, and the human sensor 400.
Setting the schedule means setting and executing the state and operation of the lighting fixture 60, the state and operation of the illuminance sensor 300, and the state and operation of the human sensor 400 according to a predetermined schedule. The description “the state of the luminaire 60” includes the state and operation of the luminaire 60, the state and operation of the illuminance sensor 300, and the state and operation of the human sensor 400.
The lighting control device 100 executes a schedule control process based on a schedule set for the lighting fixture 60, the illuminance sensor 300, and the human sensor 400.
The schedule setting method includes, for example, a weekly schedule setting for setting a schedule on each day of the week and an annual schedule setting for setting a schedule on a predetermined day of one year.
In addition, the schedule includes a time mode schedule (hereinafter referred to as a time schedule) executed by specifying a time and a timer mode schedule (hereinafter referred to as a timer schedule) executed by specifying an elapsed time. .

First, the time schedule setting method will be described.
The lighting control apparatus 100 includes a time schedule setting unit 1531 and a scene storage unit 1532 in the storage unit 150.
FIG. 13 is a diagram illustrating an example of the configuration of the time schedule setting unit 1531 according to the present embodiment. FIG. 14 is a diagram showing an example of the scene storage unit 1532 according to the present embodiment.

  As shown in FIG. 13, in the time schedule setting unit 1531, four time schedules JS1 to JS4 set in the time mode are set. The number of time schedules stored in the time schedule setting unit 1531 may be four or more, or four or less.

In the time schedule, time and scene are associated with each other.
For example, the time schedule JS1 executes scene 2 from 8:00, executes scene 3 from 10:00, executes scene 3 from 15:00, executes scene 3 from 18:00, and 20:00 This means that scene 2 is executed and scene 1 is executed from 23:00.

The time schedule setting unit 1531 is set by the user using the remote control device 80, the portable terminal 71, or the like. In addition, the setting value stored in the time schedule setting unit 1531 can be deleted or changed using the remote control device 80 or the portable terminal 71.
In addition, 10 times and scenes can be set for each time schedule, and when 10 or more times are set, it may not be accepted. The number of times and scenes that can be set for each time schedule may be 10 or more.

  A plurality of scenes are defined in the scene storage unit 1532. As shown in FIG. 14 as scene X (X = 1, 2,..., 6), for example, six scenes 1 to 6 are set, but the scene stored in the scene storage unit 1532 The number may be 6 or more, or 6 or less.

A scene is the state of the lighting fixture 60 defined by the illuminance, color temperature, and operation of the lighting fixture 60, the state, mode, and operation of the illumination sensor 300, the state, mode, and operation of the human sensor 400. . Or it is the state of the lighting fixture 60, and the surrounding condition.
In the scene storage unit 1532, the state of the luminaire 60 (illuminance, color temperature, dimming rate, operation, etc.), the state of the human sensor 400, the illuminance sensor 300, and the like are defined for each scene.
As shown in FIG. 14, for each scene, for example, target dimming rate, target illuminance, illuminance sensor, upper limit dimming rate, lower limit dimming rate, absent dimming rate, fade-in time, fade-out time, human sensor It has items of mode, human sensor holding time, absent fade time, OFF delay time, and color temperature.
FIG. 14 shows an example of specific values set for each item in the scene storage unit 1532.

  The scene storage unit 1532 is assumed to have preset values for each item. However, it may be set by the user using the remote control device 80, the portable terminal 71, or the like.

Next, a function for setting a weekly schedule and an annual schedule using the time schedule set in the time schedule setting unit 1531 will be described.
The lighting control device 100 includes a weekly schedule 1533 and an annual schedule 1534 in the storage unit 150.
FIG. 15 is a diagram showing an example of the weekly schedule 1533 according to the present embodiment. FIG. 16 is a diagram showing an example of the annual schedule 1534 according to the present embodiment.

As shown in FIG. 15, in the weekly schedule 1533, any one of four time schedule patterns (JS1 to JS4) is assigned to each day of the week from Sunday to Saturday.
The weekly schedule 1533 is set by the user using the remote control device 80 or the portable terminal 71, for example.

Hereinafter, an example of a method for setting the weekly schedule 1533 will be described.
If “JS-” is assigned to the day of the week, the day of the week becomes NULL.
The monitor request returns a schedule pattern (JS1-JS4 and JS-) in response to the request for the day of the week.
When there is a schedule day assignment reset request (reset reception at the time of day display), the schedule pattern of the target day of the week is deleted (NULL).
Even if a schedule for which no schedule pattern is set is assigned, the schedule is not executed for the assigned day. Continue the previous day's schedule.

As shown in FIG. 16, the annual schedule 1534 can set a scene with respect to a month and day. For example, scenes for a predetermined day (for example, for 30 days) may be set annually. On the day specified by the annual schedule 1534, the annual schedule is prioritized and executed instead of the weekly schedule. This makes it possible to assign a special scene on a specific day such as a holiday.
The annual schedule 1534 is set by the user using the remote control device 80 or the portable terminal 71, for example.

Next, a time schedule operation (time schedule control method) by the illumination control device 100 will be described.
An outline of time schedule operation will be described below.
When receiving the time schedule execution instruction, the lighting control device 100 performs the time schedule operation using the timer unit 140.
If the time schedule execution instruction is not received by default, that is, the time schedule operation is not performed.
When the lighting control device 100 receives the time schedule cancel instruction, the lighting control device 100 cancels the time schedule operation and continues the currently executed mode (control state).

  The time schedule execution instruction or the time schedule cancellation instruction is transmitted to the controller 10 by the operation of the remote control device 80, the portable terminal 71, etc. by the user.

The lighting control device 100 receives a time schedule execution instruction or a time schedule cancellation instruction.
When inputting the time schedule execution instruction, the lighting control device 100 executes the time schedule operation according to the weekly schedule 1533 and the annual schedule 1534 stored in the storage unit 150.

Below, an example of the operation method of the time schedule driving | operation of the controller 10 which concerns on this Embodiment is described.
(1) Contact input, dimmer operation, and manual operation shall be prioritized. If settings are made during time schedule operation, the mode changes to setting mode. When timed out in the setting mode, it shifts to time schedule operation.
(2) If there is a day of the week (NULL) for which no time schedule is input, the time schedule operation is canceled at 0:00. When the time schedule operation is canceled, the operation before the time schedule operation (normal operation or scene operation) is performed. If the day of the week on which the time schedule is input comes, the time schedule operation is executed. At this time, it is executed when the time set in the time schedule comes.
(3) When recovering from a power failure during time schedule operation, the latest time schedule after the end of the power failure is executed.
(4) When a start command (time schedule execution instruction) for time schedule operation is received and the motion sensor is linked, the time schedule operation is executed when the presence sensor is “present” and the time schedule operation is performed when “absence” is set. Stop. If other remote control operations (manual, automatic, scene, extinguish) are performed during the start of the time schedule operation, the time schedule operation is stopped and operates according to the operation.
(8) When the specific day schedule is executed by the designation from the user, the time schedule set on the earliest month and day of the annual schedule is executed.

  The above is an example of the operation method of the time schedule operation, and the time schedule operation may be executed by an operation method other than the above.

Next, a timer schedule control method using a timer schedule in the timer mode will be described.
First, a timer schedule setting method will be described.
The lighting control device 100 includes a timer schedule setting unit 1535 (timer schedule) in the storage unit 150.
FIG. 17 is a diagram illustrating an example of the configuration of the timer schedule setting unit 1535 according to the present embodiment.
In the timer schedule, relative time is set instead of setting absolute time (time).

  As shown in FIG. 17, timer schedules TS <b> 1 to TS <b> 4 that are four patterns set in the timer mode are set in the timer schedule setting unit 1535. The number of timer schedules stored in the timer schedule setting unit 1535 may be four or more, or four or less.

In the timer schedule, an elapsed time from an arbitrary time point and a state (scene) (scene information) of the lighting fixture 60 are set in association with each other. As described above, the state of the luminaire 60 includes the state and operation of the luminaire 60, the state and operation of the illuminance sensor 300, the state and operation of the human sensor 400, and the like.
The scene is executed until the set elapsed time has elapsed from the start time of the timer schedule. The input time is in seconds, from 00 minutes 01 seconds to 23 minutes 59 seconds.

  For example, the timer schedule TS1 shown in FIG. 17 executes scene 2 from the start time of timer schedule TS1 to 59 seconds, executes scene 1 from 59 seconds to 1 minute 30 seconds, and after 1 minute 30 seconds has elapsed. Scene 3 is executed until 2 minutes 30 seconds, Scene 1 is executed from 2 minutes 30 seconds to 3 minutes 10 seconds, Scene 2 is executed from 3 minutes 10 seconds to 4 minutes 20 seconds, 4 minutes 20 seconds Scene 1 is executed from 5 seconds to 5 minutes, Scene 3 is executed from 5 minutes to 6 minutes 30 seconds, Scene 1 is executed from 6 minutes 30 seconds to 7 minutes 10 seconds, 7 minutes 10 minutes This means that scene 2 is executed from 8 minutes 20 seconds after the elapse of seconds, and scene 1 is executed from 15 minutes after 8 minutes 20 seconds.

  The timer schedule setting unit 1535 is set by the user using the remote control device 80, the portable terminal 71, or the like. In addition, the setting value stored in the timer schedule setting unit 1535 can be deleted or changed using the remote control device 80 or the portable terminal 71.

Further, for each timer schedule, N elapsed times and scenes can be set, and when N or more are to be set, they may not be accepted. N is, for example, ten. The elapsed time and the number of scenes that can be set for each timer schedule may be N or more or N or less.
The set scene is executed until the set time elapses.

Next, timer schedule operation (timer schedule control method) by the illumination control device 100 will be described.
The lighting control device 100 executes a timer schedule operation when a timer schedule execution instruction is input.
The input unit 110 inputs a timer schedule execution instruction that instructs execution of control of the lighting fixture 60 according to the timer schedule. The timer schedule execution instruction includes start time related information that is information related to the start time of starting the timer schedule.
When a timer schedule execution instruction is input from the input unit 110, the control unit 130 outputs a control command for controlling the lighting fixture 60 according to the timer schedule. When a timer schedule execution instruction is input from the input unit 110, the control unit 130 calculates the start time of the timer schedule based on the start time related information included in the timer schedule execution instruction and outputs it to the timer unit 140. To do.

The timer unit 140 starts counting elapsed time from the start time using a timer function provided in the controller 10. The timer unit 140 or the input unit 110 may calculate the start time. The control unit 130 outputs a control command for controlling the lighting fixture 60 in accordance with the timer schedule based on the elapsed time counted from the start point by the timer unit 140.
The PWM amplifier circuit 600 (dimming circuit) receives a control command from the control unit 130, generates a PWM signal (lighting control signal) for controlling the lighting fixture 60 based on the input control command, and outputs the PWM signal to the lighting fixture 60. To do.

  The input unit 110 is, for example, a presence / absence detection signal of the human sensor 400, a signal indicating the (ON / OFF) state of the contact (that is, an opening / closing signal indicating the opening / closing state of the port), the remote control device 80 or the portable terminal 71. An execution request signal or the like is input as a timer schedule execution instruction. In other words, the timer schedule operation is executed with the presence / absence of the human sensor 400, ON / OFF of the contact, and a request from the user by the remote control device 80 or the portable terminal 71 as a trigger.

  For example, when the lighting control device 100 receives a presence detection signal from the human sensor 400, when the timer schedule TS2 is set to be executed, the input unit 110 inputs the presence detection signal as a timer schedule execution instruction. At this time, the input unit 110 adds the time when the presence detection signal is input as start time related information to the timer schedule execution instruction and outputs the information to the control unit 130. Alternatively, when the illumination control device 100 receives an absence detection signal from the human sensor 400, the absence detection signal is a timer schedule release instruction when the execution of the timer schedule TS2 is set to be canceled.

  When receiving the timer schedule release instruction, the lighting control apparatus 100 may continue the scene at the time when the timer schedule release instruction is received. Alternatively, the lighting control device 100 may receive a timer schedule cancel instruction and execute a predetermined scene (for example, immediately turn off immediately, gradually turn off, etc.) when the timer schedule ends.

For example, the lighting control device 100 inputs an open / close signal indicating the ON / OFF state of the contacts 1 and 2 (that is, a signal indicating the open / close state of the port), and the ON / OFF state of the contact derived from the input open / close signal When the timer schedule is set to be executed based on the above, the input unit 110 inputs an open / close signal indicating the ON / OFF state of the contact as a timer schedule execution instruction. Here, the (ON / OFF) of the contacts 1 and 2 and the (close / open) of the ports 510 and 520 correspond to each other.
At this time, the input unit 110 adds the time when the open / close signal is input as start time related information to the timer schedule execution instruction and outputs the information to the control unit 130.
Alternatively, when the ON / OFF state of the input contact is set to cancel the execution of the timer schedule TS2, the signal indicating the ON / OFF state of the contact is a timer schedule cancel instruction.

  Alternatively, a timer schedule execution instruction and a timer schedule release instruction may be received directly from the remote control device 80 or the portable terminal 71.

An outline of the operation of the timer schedule operation by the illumination control device 100 will be described below.
When inputting the timer schedule execution instruction, the input unit 110 outputs the input timer schedule execution instruction to the control unit 130.
When inputting the timer schedule execution instruction from the input unit 110, the control unit 130 extracts the timer schedule corresponding to the input timer schedule execution instruction from the timer schedule setting unit 1535 of the storage unit 150, and executes the extracted timer schedule.

FIG. 18 is a time chart for explaining timer schedule operation in which the timer schedule TS2 is executed with the human sensor 400 as a trigger.
In FIG. 18, the timer schedule operation will be described using a specific example.
Here, it is assumed that the lighting control apparatus 100 inputs the presence detection signal of the human sensor 400 as a timer schedule execution instruction and executes the timer schedule TS2 (FIG. 17). In addition, the illumination control device 100 inputs the absence detection signal of the human sensor 400 as a timer schedule cancellation instruction, and cancels execution of the timer schedule TS2.

As shown in FIG. 18, human sensor 400 detects presence at time T1 and detects absence at time T5.
The input unit 110 inputs the presence detection signal of the human sensor 400 as a timer schedule execution instruction at T1.
When the input unit 110 inputs a timer schedule execution instruction, the timer unit 140 starts counting. The time T1 is set as the start time. The timer unit 140 starts counting and the control unit 130 starts executing the timer schedule TS2.

(A) The illumination control device 100 executes the scene 2 for 10 seconds from T1 to T2.
(B) The illumination control apparatus 100 executes the scene 1 for 12 seconds from T2 to T3.
(C) The illumination control device 100 executes the scene 3 for 8 seconds from T3 to T4.
(D) The lighting control apparatus 100 starts the scene 4 from T4, and executes the scene 4 for 5 seconds until the human sensor 400 inputs the absence detection signal as a schedule cancellation instruction at T5.
When inputting the timer schedule cancel instruction at T5, the lighting control device 100 cancels the timer schedule operation (timer mode) and returns the lighting fixture to the state before the timer schedule operation is started.

  When the above (a) to (d) are applied to a specific operation, the following (a1) to (d1) are obtained. For example, it is assumed that timer schedule operation (timer mode) is set for the lighting fixture 60 that illuminates a work of art in a museum or the like. It is assumed that the lighting fixture 60 is normally turned off. When a person comes in front of a work of art, the presence sensor 400 detects the presence, and the timer schedule TS2 is executed to realize a demonstration by the lighting apparatus 60 as shown in the following (a1) to (d1). .

(A1) When a person comes, the light turns on at a color temperature of 5000 K, and the brightness gradually becomes 100% over 10 seconds from the start time (scene 2).
(B1) Thereafter, the brightness of 100% output continues for 12 seconds with the color temperature of 5000K (scene 1).
(C1) Next, the brightness gradually decreases to 50% output over 8 seconds, and the color temperature gradually changes to the light bulb color (Scene 3).
(D1) Thereafter, the brightness is maintained at an output of 50%, the color temperature gradually decreases, and further approaches the light bulb color (scene 4).
In the time chart of FIG. 18, since the timer schedule cancellation instruction (that is, absence detection signal) is input 5 seconds after the start of the scene 4, the timer schedule operation is canceled and the lighting apparatus is turned off.

  As described above, by performing the timer schedule operation in preference to the time schedule operation, it is possible to provide a lighting device with higher performance.

  Next, a description will be given of a method in which the illumination control apparatus 100 inputs an open / close signal indicating the open / close state of the contact, and executes the timer schedule operation based on the input ON / OFF state of the contact.

Here, a specific example of a function linked with the open / close (ON / OFF) state of the contact will be described.
The controller 10 includes two ports 510 and 520, and switches between input and output by a control signal. The contact input / output circuit 500 is connected to the external contact 1 and the contact 2 through the two ports 510 and 520. Switching between the input and output of the two ports 510 and 520 is set from the remote control device 80 or the portable terminal 71. Input / output can be set for each port, and in the case of combination setting, two ports are used simultaneously. For example, in the contact input, it is set so that the contact interlocking is executed when it becomes active and the control state before the activation is shifted when it becomes inactive.

<Schedule activation interlock>
In the schedule activation interlock, the timer schedule operation is executed / stopped according to the contact input status (corresponding to contact input, port opening / closing signal). Alternatively, the contact combination and the timer schedule can be set in association with each other, and the timer schedule can be selected by the contact combination.

FIG. 19 is a diagram illustrating an example of schedule activation setting in units of ports.
FIG. 20 is a diagram illustrating an example of schedule activation setting in a port combination.
The setting data in FIGS. 19 to 20 can be set using the remote control device 80 or the portable terminal 71, for example. The setting data in FIGS. 19 to 20 input using the remote control device 80 or the portable terminal 71 is input by the input unit 110 and stored in the storage unit 150.
Here, positive logic for processing a signal with active “L” is used, but the output logic may be set with negative logic for processing a signal with active “H”.
In the following description, “L”, “closed”, and “ON” correspond as contact or port states, and “H”, “open”, and “OFF” correspond.

When the contact 1 or 2 is in the open / closed state, the timer schedule is started / stopped. For example, the timer schedule may be executed when the contact 1 is closed, and the timer schedule may be executed when the contact 1 is open.
As shown in FIG. 19, for example, the timer schedule TS2 may be executed when the contact 2 is closed, and the timer schedule TS1 may be executed when the contact 2 is closed.

  As shown in FIG. 20, the control content can be set for the combination of contacts. For example, when “Contact 1 is open, Contact 2 is open”, normal operation is performed. When “Contact 1 is closed, Contact 2 is open”, the timer schedule TS1 is executed. When “Contact 1 is open, Contact 2 is closed” The timer schedule TS2 may be executed, and the timer schedule TS3 may be set to be executed when “contact 1 is closed and contact 2 is closed”.

<Contact input scene interlocking>
A case where contact input and scene execution are linked (contact input scene linkage) will be described.
Contact input scene linkage is valid only when the function is contact input.
In the contact input scene linkage, a scene is executed according to the input state of the contact. In the case of contact combination, it can be used as demand control.

FIG. 21 is a diagram illustrating an example of scene execution settings in units of ports.
FIG. 22 is a diagram illustrating an example of scene execution settings for port combinations.
FIG. 23 is a diagram illustrating an example of a priority order for contacts.
The setting data of FIGS. 21 to 23 can be set using the remote control device 80 or the portable terminal 71, for example. The setting data of FIGS. 21 to 23 input using the remote control device 80 or the portable terminal 71 is input by the input unit 110 and stored in the storage unit 150.

After the scene execution, if there is a contact input when normal operation is performed, the scene corresponding to the contact input is executed.
The output logic may be positive logic or negative logic.

As an operation example of the contact input scene interlocking, for example, as shown in the following (a) and (b), there is a case where the scene (operation mode) when absent is changed by opening and closing the contact 1.
(A) When contact 1 is “H” (OFF) (open), normal operation (remaining mode, dimming rate at absence 10%)
(A) When contact 1 is “L” (ON) (closed), scene 1 is executed (energy saving mode, dimming rate when absent, 10%, OFF delay time 60 seconds)

As described above, the linkage between the scene and the contact input and the linkage between the timer schedule and the contact input are valid only when the contact input function is selected in the controller 10.
Next, a specific example of an output interlocking function that opens and closes contacts according to the state of the illumination control system 900 will be briefly described.

<Scene execution status output>
Open and close the corresponding contacts according to the scene execution state. The scene execution state output is valid only when the contact output function is selected in the controller 10.
FIG. 24 is a diagram illustrating an example of a scene execution state output in units of ports.
FIG. 25 is a diagram illustrating an example of the scene execution state output in the port combination.
The setting data of FIGS. 24 to 25 can be set using the remote control device 80 or the portable terminal 71, for example. The setting data of FIGS. 24 to 25 input using the remote control device 80 or the portable terminal 71 is input by the input unit 110 and stored in the storage unit 150.
The output logic can be set to either positive logic or negative logic.

<Light on / off status output>
The on / off state output opens and closes the corresponding contact according to the state of the PWM dimming signal. This is an operation for each output port only. Contact 1 or contact 2 is opened and closed in the operating state of the PWM dimming signal.
The on / off state output is operated as follows, for example.
(A) PWM output 1 corresponds to contact 1. “Closed” when “Automatic”, “Open” when “Off”.
(A) PWM output 2 corresponds to contact 2. “Closed” when “Automatic”, “Open” when “Off”.
The output logic can be set to either positive logic or negative logic.

<Human sensor status output>
Depending on the presence / absence state of the human sensor 400, the contact 1 or the contact 2 is opened and closed. This is an operation for each output port only.
The human sensor state output is operated as follows, for example.
(A) When the presence sensor is “present”, contact 1 or contact 2 is “closed”
(B) When the presence sensor is “absent”, contact 1 or contact 2 is “open”
The output logic can be set to either positive logic or negative logic.

<Light sensor output>
The corresponding contact is opened / closed according to the light / dark state of the illuminance sensor 300. This is an operation for each output port only. The contact 1 or the contact 2 is opened and closed in a light / dark state of the illuminance sensor 300 (based on the target illuminance).
The illuminance sensor state output is operated as follows, for example.
(A) When the illuminance sensor is “bright”, contact 1 or contact 2 is “closed”
(B) When the illuminance sensor is “dark”, contact 1 or contact 2 is “open”
The output logic can be set to either positive logic or negative logic.

<Ventilation fan interlocking output>
The ventilation fan interlocking output is an extended function of the human sensor state output. In the absence of the human sensor 400, the corresponding contact is opened and closed after the set delay time. Simultaneously with the contact output, the PWM output 2 is controlled after the delay time.
This is an operation for each output port only.
The ventilator fan output is operated as follows, for example.
(A) When the presence sensor is “present”, contact 1 or contact 2 is “closed”, and when the presence sensor is “absence”, contact 1 or contact 2 is “open” after the delay time.
(A) When the presence sensor is “present”, the PWM output 2 is “automatic”, and when the presence sensor is “absent”, the PWM output 2 is “off” after the delay time.
The output logic can be set to either positive logic or negative logic.

As described above, in the controller 10 according to the present embodiment, it is possible to provide a lighting device with higher performance by performing the timer schedule operation in preference to the time schedule operation.
