However, FIG. 1 shows a state in which the LAN cable is laid inside the side wall W3 and on the back side of the ceiling C. Various networks that can exchange data between any two of a plurality of connected nodes may be applied in place of the LAN 3. That is, for example, instead of the LAN 3, other types of communication networks such as the Internet or a Bluetooth (registered trademark) personal network may be used. Moreover, it is good also as a form which provides the signal wire | line which each connects between the lighting fixture 1 and the lighting control apparatus 2, and transmits / receives data via this signal wire | line.

  FIG. 3 is a block diagram showing an electrical circuit configuration of the illumination system 100. In addition, since all the several lighting fixtures 1 have the same structure, in FIG. 3, the structure of the one lighting fixture 1 and the illumination control apparatus 2 is shown.

Each of the two main light sources 14 includes LED groups 14a-N and 14a-L, power supply circuits 14b-N and 14b-L, PWM (pulse width modulation) generation circuits 14c-N and 14c-L, and a communication interface (IF). 14d-N, 14d-L. However, in FIG. 3, only the configuration for one main light source 14 is illustrated.
Each of the LED groups 14a-N and 14a-L includes a large number of LEDs. The LEDs included in the LED groups 14a-N each emit daylight white light. Each of the LEDs included in the LED group 14a-L emits light bulb color light.
The power supply circuits 14b-N and 14b-L are connected to the LED groups 14a-N and 14a-L, respectively. The power supply circuit 14b-N supplies a drive current for causing the LEDs included therein to emit light, and the power supply circuit 14b-L supplies the LED group 14a-L to the LED group 14a-L.
The PWM generation circuits 14c-N and 14c-L are connected to the power supply circuits 14b-N and 14b-L, respectively. The PWM generation circuit 14c-N generates a PWM signal for causing the LED group 14a-N to emit light in a light emission state represented by white setting data D2 described later, and supplies the PWM signal to the power supply circuit 14b-N. The PWM generation circuit 14c-L generates a PWM signal for causing the LED group 14a-L to emit light in a light emission state represented by a light bulb color setting data D3 described later, and supplies the PWM signal to the power supply circuit 14b-L.
The communication interfaces 14d-N and 14d-L are connected to the PWM generation circuits 14c-N and 14c-L, respectively. The communication interfaces 14d-N and 14d-L receive data transmitted through the LAN 14 with the communication address assigned to the communication interface 14d-N and 14d-L as a destination. The communication interface 14d provides the received data to the connected PWM generation circuits 14c-N and 14d-L.

Each of the two sub light sources 15 includes an LED group 15a, a power supply circuit 15b, a PWM generation circuit 15c, and a communication interface 15d. However, in FIG. 3, only the configuration for one sub-light source 15 is shown.
The LED group 15a includes a large number of LEDs each emitting blue light.
The power supply circuit 15b supplies a drive current for causing each LED included in the LED group 15a to emit light to the LED group 15a.
The PWM generation circuit 15c generates a PWM signal for causing the LED group 15a to emit light in a light emission state represented by blue setting data D4 described later, and supplies the PWM signal to the power supply circuit 15b.

The lighting control device 2 includes a processor 21, a main storage unit 22, an auxiliary storage unit 23, a button group 24, a display 25, a communication interface 26, and a bus 27.
In the lighting control device 2, a computer is configured by connecting the processor 21, the main storage unit 22, and the auxiliary storage unit 23 through a bus 27.
The processor 21 corresponds to the central part of the computer. The processor 21 executes control processing to be described later according to the operating system and application programs.
The main memory unit 22 corresponds to the main memory portion of the computer. The main storage unit 22 includes a nonvolatile memory area and a volatile memory area. The main storage unit 22 stores an operating system and application programs in a nonvolatile memory area. The main storage unit 22 may store data necessary for the processor 21 to execute processing for controlling each unit in a nonvolatile or volatile memory area. The main storage unit 22 uses the volatile memory area as a work area in which data is appropriately rewritten by the processor 21.
The auxiliary storage unit 23 corresponds to the auxiliary storage portion of the computer. The auxiliary storage unit 23 is, for example, an EEPROM (electrically erasable programmable read-only memory). The auxiliary storage unit 23 may be another storage device such as a hard disk drive (HDD) or a solid state drive (SSD). The auxiliary storage unit 23 stores data used when the processor 21 performs various processes and data generated by the processes in the processor 21. The auxiliary storage unit 23 stores application programs.

  The application program stored in the main storage unit 22 or the auxiliary storage unit 23 includes a control program describing a procedure of control processing described later. This control program is typically stored in the main storage unit 22 or the auxiliary storage unit 23 when the lighting control device 2 is transferred to the user. However, the hardware of the lighting control device 2 may be transferred to the user in a state where the control program is not stored in the main storage unit 22 or the auxiliary storage unit 23. Then, the control program may be written in the main storage unit 22 or the auxiliary storage unit 23 in accordance with an instruction from the user or the like. In this case, the control program may be transferred to a user by being recorded on a removable recording medium such as a magnetic disk, a magneto-optical disk, an optical disk, or a semiconductor memory, or downloaded via a network.

The button group 24 includes a plurality of buttons. These buttons are pressed by the operator for various operations related to the control of the lighting apparatus 1.
The display 25 displays information to be notified to the operator such as the lighting state of the lighting fixture 1 under the control of the processor 21.
The communication interface 26 transmits various setting data, which will be described later, to the lighting apparatus 1 under an instruction from the processor 21.

The auxiliary storage unit 23 is provided with a setting data table 23a.
FIG. 4 is a diagram showing the configuration of the data record R1 included in the setting data table 23a.
The setting data table 23a is a set of many data records R1. The data record R1 describes white setting data D2, light bulb color setting data D3, and blue setting data D4 in association with the color temperature data D1. The color temperature data D1 indicates a color temperature value or a code for identifying the color temperature. Each setting data D2, D3, D4 represents a condition of a PWM signal for causing the LED group to emit light in a desired lighting state.

Next, operation | movement of the illumination system 100 comprised as mentioned above is demonstrated.
The lighting fixture 1 and the lighting control apparatus 2 operate by receiving supply of commercial power, for example. The processor 21 always executes control processing based on the control program stored in the main storage unit 22 or the auxiliary storage unit 23 in a state where commercial power is supplied.
FIG. 5 is a flowchart of control processing by the processor 21. Note that the content of the processing described below is an example, and various processing that can obtain the same result can be used as appropriate. That is, for example, it is possible to change the order of some processes.

In step Sa1, the processor 21 waits for a predetermined color change condition to be satisfied. As an example, the processor 21 waits for an operation for changing the color temperature to be performed by the button group 24. Then, if the corresponding operation is performed, the processor 21 determines that the color change condition is satisfied and determines Yes, and proceeds to step Sa2.
In step Sa2, the processor 21 determines the lighting fixture 1 whose color temperature is to be changed. As an example, the processor 21 determines the target lighting fixture 1 based on the operation of the button group 24 by the operator for designating the lighting fixture 1.

  In step Sa3, the processor 21 sets the changed color temperature. As an example, the processor 21 obtains a color temperature by receiving an input of the color temperature by the operation of the button group 24 by the operator for designating the luminaire 1, and sets this as the changed color temperature. Thus, when the processor 21 executes the control process based on the control program, the computer having the processor 21 as a central part functions as a setting means for setting the color temperature of the illumination light.

In step Sa4, the processor 21 transmits the white color change data. Specifically, the processor 21 acquires the white setting data D2 described in the data record R1 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3 from the setting data table 23a. The processor 21 changes the white color as transmission data including the white color setting data D2 and destined to the respective communication addresses of the communication interfaces 14d-N provided in the two main light sources 14 of the luminaire 1 determined in step Sa2. Generate data. Then, the processor 21 sends the white color change data thus generated from the communication interface 26 to the LAN 3. The processor 21 may generate two white color change data individually destined for two communication addresses for each of the two communication interfaces 14d-N, or 1 for both of the two communication addresses. Two white color change data may be generated.
When the white color change data is transmitted by the LAN 3 to the communication interface 14d-N to which the destination communication address is assigned, the communication interface 14d-N receives the white color change data. The communication interface 14d-N writes the white setting data D2 included in the received color change data in a storage unit provided in the PWM generation circuit 14c-N.
The PWM generation circuit 14c-N generates a PWM signal under the condition indicated by the white setting data D2 stored in the storage unit when the lighting fixture 1 is to be turned on. The power supply circuit 14b-N always supplies a drive current to the LED group 14a-N when the lighting fixture 1 is in a state to be lit. However, the power supply circuit 14b-N adjusts the light emission intensity of the LED group 14a-N by controlling the magnitude of the drive current by PWM control based on the PWM signal generated by the PWM generation circuit 14c-N. Thereby, LED group 14a-N emits the light of the intensity | strength according to the white setting data D2.

In step Sa5, the processor 21 transmits the light bulb color change data. Specifically, the processor 21 acquires the light bulb color setting data D3 described in the data record R1 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3 from the setting data table 23a. The processor 21 includes the light bulb color setting data D3, and the light bulb is transmitted as transmission data whose destination is the communication address of each of the communication interfaces 14d-L provided in the two main light sources 14 of the lighting fixture 1 determined in step Sa2. Generate color change data. Then, the processor 21 sends the light bulb color change data generated in this way from the communication interface 26 to the LAN 3. As with the white color change data, the processor 21 may generate two light bulb color change data that are individually addressed to two communication addresses, or one light bulb color change that is addressed to both of the two communication addresses. Data may be generated.
When the light bulb color change data is transmitted by the LAN 3 to the communication interface 14d-L to which the destination communication address is assigned, the communication interface 14d-L receives the light bulb color change data. The communication interface 14d-L, the PWM generation circuit 14c-L, and the power supply circuit 14b-L perform operations similar to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described above. Thereby, LED group 14a-L emits the light of the intensity | strength according to the lightbulb color setting data D3.

  Light in which daylight white light emitted from the LED group 14a-N and light bulb color light emitted from the LED group 14a-L are mixed becomes illumination light. The color temperature of the illumination light is determined by the ratio between the intensity of light emitted from the LED group 14a-N and the intensity of light emitted from the LED group 14a-L. The white setting data D2 and the light bulb color setting data D3 are determined by, for example, the designer of the lighting fixture 1 or the lighting control device 2 so that the intensity ratio is a ratio at which an associated color temperature is obtained.

In this way, the two main light sources 14 simultaneously emit illumination light of similar intensity and color temperature. These illumination lights pass through the cover 13 and illuminate the surroundings.
Thus, when the processor 21 executes the control process based on the control program, the computer having the processor 21 as the central part determines the light emission condition of the main light source 14 based on the set color temperature. It functions as a determination means.

In step Sa6, the processor 21 transmits the blue color change data. Specifically, the processor 21 acquires the blue setting data D4 described in the data record R1 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3 from the setting data table 23a. The processor 21 includes the blue setting data D4, and the blue change data is transmitted as transmission data with the respective communication addresses of the communication interfaces 15d provided in the two sub light sources 15 of the lighting fixture 1 determined in step Sa2 as destinations. Generate. Then, the processor 21 sends the blue color change data generated in this way from the communication interface 26 to the LAN 3. Similarly to the white color change data, the processor 21 may generate two blue color change data individually addressed to two communication addresses, or one blue color change data addressed to both of the two communication addresses. It may be generated.
When the blue change data is transmitted by the LAN 3 to the communication interface 15d to which the destination communication address is assigned, the communication interface 15d receives the blue change data. The communication interface 15d, the PWM generation circuit 15c, and the power supply circuit 15b perform operations similar to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described above. Thereby, the LED group 15a emits blue light having an intensity corresponding to the blue setting data D4.

In this way, the two auxiliary light sources 15 simultaneously emit blue effect light having the same intensity. These effect lights are incident on the cover 13.
Thus, when the processor 21 executes the control process based on the control program, the computer having the processor 21 as the central part determines the light emission condition of the auxiliary light source 15 based on the set color temperature. It functions as a determination means.
Further, the function as the notification means is realized by the cooperation of the computer having the processor 21 as a central part and the communication interface 26.

The cover 13 transmits incident light and scatters a part of the light, so that the cover 13 itself appears to shine. Both the illumination light emitted from the two main light sources 14 and the effect light emitted from the two sub-light sources 15 are incident on the cover 13 and scatter them. Therefore, the apparent color of the cover 13 is that of the illumination light. It becomes a mixed color of the color and the color of the effect light. As can be seen from FIG. 2, the main light source 14 is close to both ends of the cover 13, and the sub light source 15 is close to the center of the cover 13. For this reason, the intensity ratio of the effect light to the illumination light becomes higher toward the center of the cover 13. As a result, the apparent color of the cover 13 becomes a gradation in which the density of blue gradually decreases from the center toward both ends.
FIG. 6 is a diagram showing the appearance of the color of the cover 13.

The blue setting data D4 is determined by, for example, the designer of the lighting fixture 1 or the lighting control device 2 so that the intensity of the effect light is such that the cover 13 is mainly lit and the above gradation appears appropriately. For example, by appropriately determining the blue setting data D4, the apparent color of the cover 13 when the illumination light is neutral white can be a gradation that gradually approaches white from the sky blue at the center toward both ends. In addition, the apparent color of the cover 13 when the illumination light is light bulb color can be a gradation that gradually approaches yellow from the central purple toward both ends.
Note that the processor 21 returns to the standby state in step Sa1 after completing the transmission of the blue color change data in step Sa6.

  As described above, according to the first embodiment, the illumination control device 2 stores the setting data table 23 a describing the light emission conditions of the main light source 14 and the sub light source 15 for causing gradation in the apparent color of the cover 13. To do. Then, the lighting control device 2 notifies the lighting conditions of the main light source 14 and the sub light source 15 to the lighting fixture 1 in which the color temperature needs to be changed. Thus, there is no need to hold the setting data table 23a individually for each lighting fixture 1. As a result, the cost of the luminaire can be reduced as compared with the case where the luminaire 1 is provided with a storage device that stores the setting data table 23a. Further, when it is desired to change the light emission conditions of the main light source 14 and the sub light source 15, only the setting data table 23a stored in the lighting control device 2 needs to be updated, and the setting data table 23a stored individually in the lighting fixture 1 is required. It becomes simpler than updating each one.

(Second Embodiment)
The illumination system 100 differs from the first embodiment in the second embodiment in that two auxiliary light sources 16 are provided instead of the two auxiliary light sources 15.

FIG. 7 is a block diagram showing a circuit configuration of the auxiliary light source 16. However, in FIG. 7, only the configuration for one sub-light source 16 is illustrated.
The auxiliary light source 16 includes LED groups 16a-R, 16a-G, 16a-B, power supply circuits 16b-R, 16b-G, 16b-B, PWM generation circuits 16c-R, 16c-G, 16c-B, and a communication interface. 16d-R, 16d-G, and 16d-B.
The LED groups 16a-R, 16a-G, and 16a-B each include a number of LEDs. Each of the LEDs included in the LED group 16a-R emits red light. Each LED included in the LED group 16a-G emits green light. Each of the LEDs included in the LED group 16a-B emits blue light.
The power supply circuits 16b-R, 16b-G, and 16b-B have the same functions as the power supply circuit 16b in the first embodiment. The PWM generation circuits 16c-R, 16c-G, and 16c-B have the same functions as the PWM generation circuit 16c in the first embodiment. The communication interfaces 16d-R, 16d-G, and 16d-B have the same functions as the communication interface 16d in the first embodiment. The power supply circuit 16b-R, the PWM generation circuit 16c-R, and the communication interface 16d-R constitute a circuit for causing the LED group 16a-R to emit light according to the setting data sent from the illumination control device 2. The power supply circuit 16b-G, the PWM generation circuit 16c-G, and the communication interface 16d-G constitute a circuit for causing the LED group 16a-G to emit light in accordance with setting data sent from the illumination control device 2. The power supply circuit 16b-B, the PWM generation circuit 16c-B, and the communication interface 16d-B constitute a circuit for causing the LED group 16a-B to emit light according to the setting data sent from the illumination control device 2.

The illumination control device 2 may have the same configuration as that of the first embodiment also in the second embodiment.
However, the illumination control device 2 according to the second embodiment is different from the first embodiment in the structure of the setting data table 23a. Moreover, the illumination control apparatus 2 in 2nd Embodiment differs from the 1st Embodiment in the content of the control processing which the processor 21 performs.

FIG. 8 is a diagram showing the configuration of the data record R2 included in the setting data table 23a in the second embodiment.
The setting data table 23a in the second embodiment is a set of a large number of data records R2. The data record R2 describes white setting data D2, light bulb color setting data D3, red setting data D11, green setting data D12, and blue setting data D13 in association with the color temperature data D1. Each setting data represents a condition of a PWM signal for causing the LED group to emit light in a desired lighting state.

Next, operation | movement of the illumination system 100 in 2nd Embodiment comprised as mentioned above is demonstrated.
FIG. 9 is a flowchart of control processing by the processor 21 in the second embodiment. Note that the content of the processing described below is an example, and various processing that can obtain the same result can be used as appropriate. That is, for example, it is possible to change the order of some processes. In FIG. 9, steps that perform the same processing as the steps shown in FIG. 5 are given the same reference numerals, and detailed descriptions thereof are omitted.
Also in the second embodiment, the processor 21 performs steps Sa1 to Sa5 in the same manner as in the first embodiment. That is, the processing of the processor 21 for changing the light emission state of the main light source 14 is the same in the first and second embodiments. However, the processor 21 acquires the white setting data D2 and the light bulb color setting data D3 from the data record R2 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3.

When the transmission of the light bulb color change data in step Sa5 is completed, the processor 21 proceeds to step Sb1.
In step Sb1, the processor 21 transmits red color change data. Specifically, the processor 21 acquires the red setting data D11 described in the data record R2 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3 from the setting data table 23a. The processor 21 includes the red setting data D11, and changes the red color as transmission data whose destination is each communication address of the communication interface 16d-R provided in each of the two sub light sources 16 of the lighting fixture 1 determined in step Sa2. Generate data. Then, the processor 21 sends the red color change data thus generated from the communication interface 26 to the LAN 3. The processor 21 may generate the two red change data individually addressed to the two communication addresses in the same manner as described for the white change data in the first embodiment, or the two communication addresses. One red change data with both addresses as destinations may be generated.
When the red change data is transmitted by the LAN 3 to the communication interface 16d-R to which the destination communication address is assigned, the communication interface 16d-R receives the red change data. The communication interface 16d-R, the PWM generation circuit 16c-R, and the power supply circuit 16b-R correspond to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described in the first embodiment. A similar operation is performed. Thereby, LED group 16a-B emits the red light of the intensity | strength according to the red setting data D11.

In step Sb2, the processor 21 transmits the green color change data. Specifically, the processor 21 acquires the green setting data D12 described in the data record R2 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3 from the setting data table 23a. The processor 21 includes the green setting data D12, and changes the red color as transmission data whose destination is each communication address of the communication interface 16d-G provided in each of the two sub light sources 16 of the lighting fixture 1 determined in step Sa2. Generate data. Then, the processor 21 sends the green change data generated in this way from the communication interface 26 to the LAN 3. The processor 21 may generate two pieces of green change data individually addressed to two communication addresses in the same manner as described for the white change data in the first embodiment, or the two communication addresses. One green change data with both addresses as destinations may be generated.
When the green change data is transmitted by the LAN 3 to the communication interface 16d-G to which the destination communication address is assigned, the communication interface 16d-G receives the green change data. The communication interface 16d-G, the PWM generation circuit 16c-G, and the power supply circuit 16b-G correspond to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described in the first embodiment. A similar operation is performed. Thereby, LED group 16a-G emits the green light of the intensity | strength according to the green setting data D12.

In step Sb3, the processor 21 transmits the blue color change data. Specifically, the processor 21 acquires the blue setting data D13 described in the data record R2 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3 from the setting data table 23a. The processor 21 changes the blue color as transmission data including the blue setting data D13 and having each communication address of the communication interface 16d-B provided in each of the two sub light sources 16 of the lighting fixture 1 determined in step Sa2 as destinations. Generate data. Then, the processor 21 sends the blue color change data generated in this way from the communication interface 26 to the LAN 3. The processor 21 may generate two blue color change data individually addressed to two communication addresses in the same manner as described for the white color change data in the first embodiment. One blue color change data destined for both of these may be generated.
When the blue change data is transmitted by the LAN 3 to the communication interface 16d-B to which the destination communication address is assigned, the communication interface 16d-B receives the blue change data. The communication interface 16d-B, the PWM generation circuit 16c-B, and the power supply circuit 16b-b correspond to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described in the first embodiment. A similar operation is performed. Thereby, LED group 16a-B emits the blue light of the intensity | strength according to the blue setting data D13.

  Light in which red light, green light, and blue light emitted from the LED groups 16a-R, 16a-G, and 16a-B are mixed is the effect light. The color of the effect light is determined by the ratio of the intensity of each of red light, green light, and blue light.

  In this way, the two sub-light sources 16 emit similar effect light simultaneously. These effect lights are incident on the cover 13.

Also in the second embodiment, gradation can be generated in the apparent color of the cover 13 by the interaction between the illumination light and the effect light. In the second embodiment, the color of the effect light can be changed variously, so that the gradation color can be arbitrarily determined.
Also in the second embodiment, the lighting control device 2 notifies the light emission conditions of the main light source 14 and the sub light source 16. Therefore, the effects described above for the first embodiment can be similarly achieved in the second embodiment.

(Third embodiment)
FIG. 10 is a diagram illustrating a construction example of the illumination system 200 according to the third embodiment. In the third embodiment, the same elements as those described in the first or second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.

The lighting system 200 includes a LAN 3, one or more lighting fixtures 4 and a lighting control device 5. However, in FIG. 10, two lighting fixtures 4 are illustrated.
The lighting fixtures 4 are all attached to the ceiling C. The luminaire 4 illuminates the room R.
The illumination control device 5 is attached to the side wall W3. The lighting control device 5 controls the lighting state of the lighting fixture 4 in response to an operation by the user.

FIG. 11 is a partially broken view showing the structure of the lighting fixture 4.
The lighting fixture 4 includes a housing 11, two main light sources 14, two sub light sources 16, a reflector 17, a cover 18, and a display 19.
The reflecting plate 17 is made of a metal such as aluminum or steel, and has an arch shape in cross section. The concave surface side of the reflecting plate 12 is painted white, for example, so as to be a reflecting surface that reflects light with high efficiency. As a material of the reflecting plate 12, a white steel plate can be preferably used. The reflecting plate 12 is fixed inside the housing 11 with the reflecting surface facing the opening surface of the housing 11. Two main light sources 14 and two sub light sources 16 are attached to the concave surface side of the reflecting plate 17. The longitudinal direction of the main light source 14 and the sub light source 16 is along the depth direction of FIG.
The cover 18 is made of acrylic, for example. The cover 18 is formed with an elongated window 18 a along the longitudinal direction of the main light source 14 and the sub light source 16 at the center in the arrangement direction of the two main light sources 14 and the two sub light sources 16. The window 18a is transparent and transmits light with almost no scattering. The region 18b other than the window 18a of the cover 18 is, for example, milky white and transmits light while being scattered. In the present embodiment, the cross-sectional shape of the cover 18 is an arch shape. And the cover 18 is attached to the housing | casing 11 in the state which obstruct | occluded the opening surface of the housing | casing 11 facing the concave surface side below.
The display 19 is disposed inside the housing 11 with its display surface facing the window 18a. The display 19 displays an arbitrary image on the display surface.

  FIG. 12 is a block diagram showing an electrical circuit configuration of the illumination system 200. In addition, since all the several lighting fixtures 4 have the same structure, in FIG. 12, the structure of the one lighting fixture 4 and the illumination control apparatus 5 is shown.

  The display device 19 included in the lighting fixture 4 further includes a display panel 19a, a display control unit 19b, and a communication interface 19c.

  The display panel 19a forms an arbitrary image. For example, a liquid crystal display panel can be used as the display panel 19a. The display panel 19a is an example of a display unit. However, as the display means, a projector or the like that projects an image on the window 18a may be employed. The display control unit 19b controls the display panel 19a so as to form an image indicated by the image data given from the illumination control device 5. The communication interface 19c receives data transmitted through the LAN 3 with the communication address assigned to itself as a destination. The communication interface 19c gives the received data to the display control unit 19b.

  The lighting control device 5 includes a processor 21, a main storage unit 22, an auxiliary storage unit 23, a button group 24, a display 25, a communication interface 26, and a bus 27. That is, the illumination control device 5 is the same as the illumination control device 2 in the first embodiment as a hardware configuration. However, the auxiliary storage unit 23 is provided with an image database 23b and setting data tables 23c and 23d instead of the setting data table 23a in the first embodiment. Further, the control program stored in the main storage unit 22 or the auxiliary storage unit 23 describes a control process to be described later.

The image database 23 b stores image data representing an image to be displayed on the display device 19. The image database 23b can store a plurality of pieces of image data each assigned with an individual image code. Thus, the auxiliary storage unit 23 has a function as storage means for storing a plurality of image data.
The processor 21 can acquire image data from the content server 500 via the LAN 3, the router 300, and the communication network 400 by the communication interface 26, and store the image data in the image database 23b. At this time, the processor 21 stores the newly acquired image data in the image database 23b in addition to the already stored image data. However, the already stored image data may be deleted according to a predetermined condition. For example, the processor 21 deletes the image data designated by the operation with the button group 24 from the image database 23b. Alternatively, for example, the processor 21 records the timing at which the image data is added to the image database 23b, and deletes the oldest added image data to the image database 23b. Alternatively, for example, the processor 21 measures the frequency used for display on the display 19 and deletes image data with a low frequency. The processor 21 deletes the image data only when adding new image data to the image database 23b causes the data amount of the image database 23b to exceed the allowable data amount. Also good.

FIG. 13 is a diagram showing the configuration of the data record R3 included in the setting data table 23c.
The setting data table 23c is a set of many data records R3. The data record R3 describes the white setting data D2 and the light bulb color setting data D3 in association with the color temperature data D1. That is, the data record R3 is obtained by removing the blue setting data D4 from the data record R1 in the first embodiment.

FIG. 14 is a diagram showing the configuration of the data record R4 included in the setting data table 23d.
The setting data table 23d is a set of a plurality of data records R4. The data record R4 describes red setting data D22, green setting data D23, and blue setting data D24 in association with the image code D21. Each setting data represents a condition of a PWM signal for causing the LED groups 16a-R, 16a-G, 16a-B of the sub light source 16 to emit light in a desired lighting state.

Next, the operation of the illumination system 200 configured as described above will be described.
The processor 21 always executes a control process based on a control program stored in the main storage unit 22 or the auxiliary storage unit 23 in a state where commercial power is supplied.

FIG. 15 is a flowchart of control processing by the processor 21 in the third embodiment. Note that the content of the processing described below is an example, and various processing that can obtain the same result can be used as appropriate. That is, for example, it is possible to change the order of some processes. In FIG. 15, steps that perform the same processing as the steps shown in FIG. 5 are given the same reference numerals, and detailed descriptions thereof are omitted.
The processor 21 performs the determination in step Sa1 as in the first embodiment. If the color is not satisfied because the color change condition is not satisfied, the processor 21 proceeds to step Sc1.
In step Sc1, the processor 21 confirms whether or not an image change condition is satisfied. As an example, the processor 21 confirms whether or not an operation for changing the display image has been performed on the button group 24. Then, if the processor 21 determines No because the image change condition is not satisfied, the processor 21 returns to step Sa1.
Thus, the processor 21 waits for the color change condition or the image change condition to be satisfied in steps Sa1 and Sc1.

  If the processor 21 determines Yes in step Sa1 because the color change condition is satisfied, the processor 21 proceeds to step Sa2. Then, the processor 21 performs steps Sa2 to Sa5 in the same manner as in the first embodiment. That is, the processing of the processor 21 for changing the light emission state of the main light source 14 is the same in the first and third embodiments. However, the processor 21 acquires the white setting data D2 and the light bulb color setting data D3 from the data record R3 including the color temperature data D1 corresponding to the color temperature acquired in step Sa3.

If the processor 21 determines Yes in step Sc1 because the image change condition is satisfied, the processor 21 proceeds to step Sc2.
In step Sc2, the processor 21 determines the lighting fixture 1 to be changed in display image. As an example, the processor 21 determines the target lighting fixture 1 based on the operation of the button group 24 by the operator for designating the lighting fixture 1.

  In step Sc3, the processor 21 determines a new image to be displayed. As an example, the processor 21 determines an image to be newly displayed based on an operation of the button group 24 by an operator for designating an image to be displayed. Thus, when the processor 21 executes the control process based on the control program, the computer having the processor 21 as a central part functions as a selection unit that selects one image data from a plurality of image data.

In step Sc4, the processor 21 transmits the red color change data. Specifically, the processor 21 acquires the red setting data D22 described in the data record R4 including the image code D21 assigned to the image determined in step Sc3 from the setting data table 23d. The processor 21 includes the red setting data D22, and changes the red color as transmission data whose destinations are the communication addresses of the communication interfaces 16d-R respectively provided in the two sub light sources 16 of the lighting fixture 1 determined in step Sc2. Generate data. Then, the processor 21 sends the red color change data thus generated from the communication interface 26 to the LAN 3. The processor 21 may generate the two red change data individually addressed to the two communication addresses in the same manner as described for the white change data in the first embodiment, or the two communication addresses. One red change data with both addresses as destinations may be generated.
When the red change data is transmitted by the LAN 3 to the communication interface 16d-R to which the destination communication address is assigned, the communication interface 16d-R receives the red change data. The communication interface 16d-R, the PWM generation circuit 16c-R, and the power supply circuit 16b-R correspond to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described in the first embodiment. A similar operation is performed. Accordingly, the LED group 16a-R emits red light having an intensity corresponding to the red setting data D22.

In step Sc5, the processor 21 transmits the green color change data. Specifically, the processor 21 acquires, from the setting data table 23d, the green setting data D23 described in the data record R4 including the image code D21 assigned to the image determined in step Sc3. The processor 21 includes the green setting data D23, and changes the green color as transmission data whose destination is each communication address of the communication interface 16d-G provided in each of the two sub light sources 16 of the lighting fixture 1 determined in step Sc2. Generate data. Then, the processor 21 sends the green change data generated in this way from the communication interface 26 to the LAN 3. The processor 21 may generate two pieces of green change data individually addressed to two communication addresses in the same manner as described for the white change data in the first embodiment, or the two communication addresses. One green change data with both addresses as destinations may be generated.
When the green change data is transmitted by the LAN 3 to the communication interface 16d-G to which the destination communication address is assigned, the communication interface 16d-G receives the green change data. The communication interface 16d-G, the PWM generation circuit 16c-G, and the power supply circuit 16b-G correspond to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described in the first embodiment. A similar operation is performed. Thereby, LED group 16a-G emits the green light of the intensity | strength according to the green setting data D23.

In step Sc6, the processor 21 transmits blue color change data. Specifically, the processor 21 acquires from the setting data table 23d the blue setting data D24 described in the data record R4 including the image code D21 assigned to the image determined in step Sc3. The processor 21 changes the blue color as transmission data including the blue setting data D24 and having each communication address of the communication interface 16d-B provided in each of the two sub light sources 16 of the lighting fixture 1 determined in step Sc2 as destinations. Generate data. Then, the processor 21 sends the blue color change data generated in this way from the communication interface 26 to the LAN 3. The processor 21 may generate two blue color change data individually addressed to two communication addresses in the same manner as described for the white color change data in the first embodiment. One blue color change data destined for both of these may be generated.
When the blue change data is transmitted by the LAN 3 to the communication interface 16d-B to which the destination communication address is assigned, the communication interface 16d-B receives the blue change data. The communication interface 16d-B, the PWM generation circuit 16c-B, and the power supply circuit 16b-b correspond to the operations of the communication interface 14d-N, the PWM generation circuit 14c-N, and the power supply circuit 14b-N described in the first embodiment. A similar operation is performed. Thereby, LED group 16a-B emits the blue light of the intensity | strength according to the blue setting data D24.

Now, the mixed light of red light, green light, and blue light emitted from the LED groups 16a-R, 16a-G, and 16a-B is the effect light. The color of the effect light is determined by the ratio of the intensity of each of red light, green light, and blue light.
In this way, the two sub-light sources 16 emit similar effect light simultaneously. These effect lights are incident on the cover 18.

In step Sc7, the processor 21 reads out the image data of the image determined in step Sc3 from the image database 23b. Then, the processor 21 generates image change data as transmission data including the image data and having the communication address of the communication interface 19c of the lighting fixture 1 determined in step Sc2 as a destination. Then, the processor 21 sends the image change data generated in this way from the communication interface 26 to the LAN 3. When the processor 21 has finished sending the image change data, the processor 21 returns to the standby state of steps Sa1 and Sc1.
When the image change data is transmitted by the LAN 3 to the communication interface 19c to which the destination communication address is assigned, the communication interface 19c receives the image change data. The communication interface 19c writes the image data included in the received image change data in a storage unit provided in the display control unit 19b. Thus, the processor 21 of the lighting control device 2 causes the lighting fixture 1 to acquire image data by transmitting the image change data. Therefore, when the processor 21 executes control processing based on the control program, the computer having the processor 21 as a central part functions as an acquisition control unit.
The display control unit 19b controls the display panel 19a so that the image indicated by the image data stored in the storage unit is always displayed when the lighting fixture 1 is to be turned on. However, an operation mode in which image display is not performed may be set by a command from the illumination control device 5. The display control unit 19b may not control the display panel 19a when an operation mode in which this image display is not performed is set.

The region 18b of the cover 18 transmits incident light and scatters a part of the light so that the region 18b itself appears to shine. Both the illumination light emitted by one of the main light sources 14 and the effect light emitted by one of the sub-light sources 16 enter the region 18b and scatter them, so the apparent color of the cover 13 is the color of the illumination light. It becomes a mixed color of the color and the color of the effect light. As can be seen from FIG. 11, the main light source 14 is close to one end of the region 18b, and the sub-light source 16 is close to the other end of the region 18b. For this reason, the intensity ratio of the effect light to the illumination light increases from the end of the cover 18 toward the center. Therefore, the apparent color of the area 18b of the cover 18 is a gradation in which the density of the effect light color gradually decreases from the central side toward the end. On the other hand, the image displayed by the display panel 19a can be seen through the window 18a. As a result, the cover 18 as a whole appears as a single image in which both sides of the image displayed by the display panel 19a are bordered with gradation by illumination light and effect light.
FIG. 16 is a diagram showing the appearance color of the cover 18.

  Here, the image displayed on the display panel 19a is arbitrary, but it is assumed to be an original image created so as to be familiar with the gradation in the region 18b. In this case, the image and the color of the effect light can be appropriately determined, and the boundary between the window 18a and the region 18b can be made inconspicuous.

  However, for example, an image acquired from an arbitrary WEB site (not shown) via the communication network 400 may be displayed on the display panel 19a. In this case, it is desirable to determine the color of the effect light so that a gradation that makes the boundary between the window 18a and the region 18b as inconspicuous as possible is formed in the region 18b. The determination of the color of the effect light may be performed by any human or the processor 21. In the former case, the data record R4 generated by describing the setting data D22, D23, D24 of each color determined by a person in association with the image code D21 of the image data indicating the image to be displayed is set. It is included in the data table 23d. In the latter case, for example, when the image data indicating the image to be displayed is added to the image database 23b, the processor 21 analyzes the image data and determines an appropriate color of the effect light. Then, the processor 21 sets the data record R4 generated by describing the setting data D22, D23, D24 of each color corresponding to the color in association with the image code D21 of the image data to be added to the image database 23b. Add to table 23d. For example, the processor 21 can determine an appropriate color of the effect light as the average color of the edge portion of the image to be displayed or as a color having a predetermined relationship with the average color.

  According to the third embodiment, the illumination control device 2 stores the setting data tables 23c and 23d describing the light emission conditions of the main light source 14 and the sub light source 16 for causing gradation in the apparent color of the cover 18. . Further, the image data is stored in the illumination control device 2. Then, image data is given from the illumination control device 2 to the luminaire 4 in which it is necessary to change the image to be displayed, and the light emission conditions of the main light source 14 and the sub light source 16 are notified. Thus, there is no need to individually hold the image database 23b and the setting data tables 23c and 23d including image data indicating each of the images to be displayed. As a result, the cost of the lighting fixture can be reduced as compared with the case where the image database 23b and the setting data tables 23c and 23d are provided in the lighting fixture 4. Further, when it is desired to change or add the relationship between the image to be displayed and the light emission conditions of the main light source 14 and the sub light source 16, it is sufficient to maintain the data only with the lighting control device 2, and each of the lighting fixtures 4 can be maintained. This is simpler than maintaining data.

This embodiment can be variously modified as follows.
In each embodiment, the color change condition may be arbitrary. Below are some examples.
(1) The processor 21 may determine that the color change condition is satisfied in response to the arrival of a time set as the timing for changing the color temperature. In this way, for example, if the illumination light is daylight white in the daytime and the illumination light is a light bulb color in the evening, the sky color of the covers 13 and 18 is changed from a color that can image a blue sky in accordance with the change of time to the sunset sky. Can be automatically changed to a color that can be imaged.
(2) The processor 21 determines that the color change condition is satisfied in response to an instruction to change the color temperature from a device not shown in FIG. 1 and FIG. 3 or FIG. 10 and FIG. Also good. In this case, for example, if the temperature is measured and a device for instructing the change to the color temperature corresponding to the temperature is connected to the LAN 3, and the temperature is set to a lower color temperature, the covers 13 and 18 are set. Can be automatically set to a color from which the temperature can be estimated.
(3) The processor 21 determines that the color change condition is satisfied in response to the fact that predetermined data has been acquired via the Internet or the like not shown in FIG. 1 and FIG. 3 or FIG. 10 and FIG. Also good. In this way, for example, weather information is acquired from a website, and the weather color is estimated when the illumination light is set to the light bulb color in fine weather and the illumination light is neutral white in rainy weather. Can be automatically set to the color that can be.

  In each embodiment, the lighting control apparatuses 2 and 5 show an example in which the lighting control apparatuses 2 and 5 are configured integrally with a so-called operation panel. However, it can be configured as a separate device from the operation panel. In this case, as the hardware of the lighting control devices 2 and 5, a general-purpose computer device for home use or a server, or an information terminal device such as a smartphone or a tablet terminal can be used.

  In each embodiment, various setting data tables may be stored in an external server or the like.

  Each embodiment can also be applied to various types of lighting fixtures having different implementation forms such as a type that is mounted on the ceiling surface in a state of protruding into the indoor space.

  In each embodiment, the main light source 14, the sub light source 15, and the sub light source 16 may each be replaced with the following configuration. For example, a light emitting unit including an LED group and a power supply device including a power supply circuit, a PWM generation circuit, and a communication interface may be configured separately. In this case, a light emitting unit is disposed in place of the main light source 14, the sub light source 15, and the sub light source 16 shown in FIGS. 2 and 11, and a power supply device is disposed in the space between the housing 11 and the reflecting plate 12. It is preferable to do. Note that the power supply circuit 14b-N, the PWM generation circuit 14c-N, and the communication interface 14d-N, and the power supply circuit 14b-L, the PWM generation circuit 14c-L, and the communication interface 14d-L included in the main light source 14 are May be incorporated into one power supply device, or may be configured as separate power supply devices. Further, the power source circuit 16b-R, the PWM generation circuit 16c-R, and the communication interface 16d-R included in the sub light source 16, the power source circuit 16b-G, the PWM generation circuit 16c-G, the communication interface 16d-G, and the power source circuit 16b-B, PWM generation circuit 16c-B, and communication interface 16d-B may all be incorporated into one power supply device, or may be configured as separate power supply devices.

  In the first and second embodiments, only one sub light source 15 or sub light source 16 may be provided. Alternatively, one main light source 14 and one sub light source 15 or sub light source 16 may be provided. Further, the main light source 14, the sub light source 15, or the sub light source 16 may include three or more.

In the third embodiment, the image change condition may be arbitrary. Below are some examples.
(1) The processor 21 may determine that the image change condition is satisfied in response to the arrival of a time set as the timing for changing the image. In this case, for example, if an image showing a bird jumping out from the first end of the window 18a is displayed while the illumination light is white in the morning and the production light is white, the bird is displayed in the clear sky. Can express the appearance of If the image showing the state of the bird flying in the center of the window 18a is displayed while the illumination light is day white in the daytime and the effect light is blue, it is possible to express the bird flying around the blue sky. Also, in the evening, if you display an image that shows the bird flying to the first end of the window 18a while the lighting light is light bulb color and the production light is blue, the bird will fly into the nest in the dusk sky. You can express how you go back.
(2) The processor 21 may determine that the image change condition is satisfied in response to an instruction to change the image from a device not shown in FIGS. 10 and 12 via the LAN 3. Specifically, for example, a temperature is measured, and a device for instructing a change to a color temperature and an image corresponding to the temperature is connected to the LAN 3. If the processor 21 sets a higher color temperature as the air temperature is lower in accordance with an instruction from the above-described device and appropriately displays a plurality of images expressing the heat, the cover 18 as a whole is hot. It can be automatically set to be a picture representing the height.
(3) The processor 21 may determine that the color change condition is satisfied in accordance with the fact that predetermined data has been acquired via the Internet or the like not shown in FIGS. 10 and 12. In this way, for example, if weather information is acquired from a website, the illumination light is displayed with a light bulb color and the sun image is displayed in fine weather, and the rain light is displayed as a neutral white and a rain image is displayed in rainy weather. The cover 18 as a whole can be automatically set to be a picture representing the weather.

  In the third embodiment, only one auxiliary light source 16 may be provided. One main light source 14 and one sub light source 16 may be provided. Further, the main light source 14 or the sub light source 16 may include three or more. However, when only one sub-light source 16 is provided, the shape of the reflector 17 is adjusted so that the effect light emitted by the one sub-light source 16 is appropriately incident on both the two regions 18b of the cover 18, or For example, another reflector is provided.

  In the third embodiment, the image database 23b may not be provided in the auxiliary storage unit 23, and image data may be acquired from an external device such as the content server 500 each time an image change condition is satisfied.

  In the third embodiment, the display control unit 19b may acquire the image data instructed from the lighting control device 5 from the content server 500 without going through the lighting control device 5.

  In the third embodiment, a moving image may be displayed on the display 19. In this case, a moving image file may be included in the image change data instead of the image data. Alternatively, the moving image data may be transmitted from the lighting control device 2 to the lighting fixture 4 using a moving image distribution technique such as streaming. When displaying a moving image on the display 19, the color temperature of the illumination light and the color of the effect light may be changed in synchronization with the progress of the moving image.
