DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0028]
(Embodiment 1)
FIG. 1 shows a configuration of a system 100 that provides a lighting service according to the first embodiment of the present invention.
[0029]
The system 100 includes a service center 1, a home 102, and a network 101 that connects the service center 1 and the home 102. A hotel 110 may be connected to the network 101. The network 101 is an arbitrary network (for example, the Internet). The network 101 may include various types of LANs including wireless LANs, WANs, telephone lines, wireless telephone lines, and the like.
[0030]
In the home 102, devices (information home appliances) such as a personal computer (PC) 104 and the lighting device 10 are placed. The home 102 may further include devices such as a television (TV) 105 and a microwave oven 106. These devices are connected to each other via a home LAN 103 installed in the home 102. The home LAN 103 is connected to the network 101.
[0031]
The illumination device 10 includes a plurality of pixels that can be controlled independently.
[0032]
A user 301 of these devices lives in the home 102. For example, the user 301 transmits the lighting service order 121 to the service center 1 using the PC 104. The transmitted order 121 is received by the service center 1 via the network 101.
[0033]
The service center 1 includes a network communication unit 3 that communicates with devices in the home 2 via the network 101, a CPU 2, a memory 4, and a display unit 5. The service center 1 can be any computer.
[0034]
The CPU 2 generates (acquires) appropriate lighting control data 131 in accordance with the lighting service order 121 received by the network communication unit 3, and executes a lighting service providing process for providing the lighting control data 131 to the lighting device 10. .
[0035]
In the memory 4, for example, lighting control data for realizing display of a plurality of fixed messages and lighting patterns is stored for each type name of the lighting device. Here, the illumination pattern refers to a pattern displayed on the illumination device that defines the illumination mode (for example, the color and / or brightness of illumination light of each pixel) for each pixel of the illumination device. The form of illumination may change with time (moving image) or may not change (still image).
[0036]
The display unit 5 is used by an administrator of the service center 1 (computer) to monitor the state of the service center 1. The display unit 5 is, for example, a CRT display.
[0037]
Communication between the service center 1 and the lighting device 10 placed in the home 102 is performed by packet transfer, for example. The packet includes a header part indicating a transfer destination and a data part carrying data to be transferred (for example, lighting control data 131). The header portion is assigned to each device placed in the home 102 and includes an address that uniquely identifies each device on the network 101. As such an address, for example, an IP address assigned to each device in accordance with the IPv6 (Internet protocol version 6) standard may be used. The IP address uniquely identifies a device connected to the Internet on the Internet.
[0038]
By configuring the header portion of the packet in this way, the packet is transferred from the service center 1 to the specific lighting device 10 placed in the home 102, or the service is sent from the specific lighting device 10 placed in the home 2 The packet can be transferred to the center 1.
[0039]
In the hotel 110, similarly to the home 102, devices (information home appliances) such as a personal computer (PC) 104 and the lighting device 10 are placed.
[0040]
FIG. 2 shows the configuration of the illumination device 10 of the present invention. The lighting device 10 is connected to the home LAN 103 and receives the lighting control data 131 via the network 101, the display unit 14 including a plurality of pixels 16 that can be controlled independently, and the received lighting control data 131. And a display control unit 13 for controlling the plurality of pixels 16 according to the above. The lighting device 10 may include a memory 12 that stores the lighting control data 131 received by the network communication unit 11.
[0041]
The form in which the lighting device 10 receives the lighting control data 131 is not limited to the form in which the lighting control data 131 is received from the network communication unit 11 via the home LAN 103. The illumination device 10 may include a recording medium access unit 15 instead of the network communication unit 11 or in addition to the network communication unit 11. The recording medium access unit 15 reads the illumination control data 131 recorded on the recording medium, thereby receiving the illumination control data 131 from the recording medium.
[0042]
When the lighting device 10 includes the recording medium access unit 15, the lighting control data 131 sent from the service center 1 may be recorded on the recording medium. The user 301 can illuminate the room where the lighting device 10 is placed in a desired form at a desired time by connecting a recording medium on which desired lighting control data 131 is recorded to the recording medium access unit 15. it can.
[0043]
Any recording medium can be used as a recording medium on which the illumination control data 131 is recorded. For example, a recording medium such as a hard disk, CD-ROM, MO, MD, DVD, or SD card can be suitably used.
[0044]
The network communication unit 11 or the recording medium access unit 15 functions as the interface unit 17 that receives the illumination control data 131 from the outside of the illumination device 10.
[0045]
The display control unit 13 generates a control signal for controlling the plurality of pixels 16 of the display unit 14 from the illumination control data 131. When each of the plurality of pixels includes a light emitting diode (LED), the display control unit 13 generates a pulse voltage signal for driving the LED as a control signal.
[0046]
The display unit 14 includes a plurality of pixels 16. The plurality of pixels 16 are arranged in a matrix, for example. The number of pixels 16 included in the display unit 14 is about 500, for example. Each of the pixels 16 emits illumination light. The display control unit 13 independently controls the brightness and color of illumination light emitted from each of the plurality of pixels 16. Thereby, various forms of illumination are realized.
[0047]
In a normal illumination form (an illumination form that does not require entertainment), the display control unit 13 emits white illumination light with the maximum brightness, regardless of the illumination control data 131 ( The pixel 16 is controlled so as to display. Thereby, the brightness and average color rendering evaluation index of the illumination provided by the illumination device 10 can be increased.
[0048]
In the form of illumination that requires entertainment, the display control unit 13 controls the plurality of pixels 16 according to the illumination control data 131. This makes it possible to illuminate a predetermined space such as one room in a desired form. In such a form of illumination, the illumination device 10 displays, for example, an illumination pattern.
[0049]
As described above, the display control unit 13 performs the second operation in which the lighting device 10 operates in the first operation mode in which the operation mode is operated in the normal illumination mode and in the illumination mode in which entertainment is required. The lighting device 10 is controlled to have a mode.
[0050]
The arrangement of the plurality of pixels 16 is not limited to the matrix arrangement shown in FIG. The plurality of pixels 16 may be arranged in a delta shape.
[0051]
Further, the display unit 14 may be divided into a plurality of separated blocks. The plurality of blocks may be arranged at different positions. For example, one block can be placed on the wall and the other block can be placed on the ceiling.
[0052]
FIG. 3A shows an example of the configuration of one pixel 16 of the illumination device 10. The pixel 16 includes three LEDs 17R, 17G, and 17B. Each of the LEDs 17R, 17G, and 17B is connected to the display control unit 13. The LEDs 17R, 17G, and 17B emit red light 51R, green light 51G, and blue light 51B, respectively. The lights 51R, 51G, and 51B constitute the illumination light 51 emitted from the pixels 16 as a whole.
[0053]
The display control unit 13 independently controls the brightness of each of the LEDs 17R, 17G, and 17B, so that the illumination light 51 emitted from the pixels 16 can have a desired brightness and color. The brightness of each of the LEDs 17R, 17G, and 17B can be controlled by controlling the pulse voltage signal that drives the LED to change the amount of current flowing through the LED.
[0054]
FIG. 3B shows another example of the configuration of one pixel 16 of the illumination device 10. In FIG. 3B, the same components as those shown in FIG. 3A are denoted by the same reference numerals, and the description thereof is omitted. In the example shown in FIG. 3B, the pixel 16 includes two LEDs 17R and 17B. A phosphor 18G is provided at a position near the LED 17B. The green phosphor 18G emits green fluorescence 61G when illuminated with a part 61B of the light emitted by the LED 17B. The lights 51R, 61G and 51B constitute the illumination light 51 emitted from the pixels 16 as a whole.
[0055]
According to the configuration of the pixel 16 shown in FIG. 3B, the LED 17G is omitted as compared with the configuration shown in FIG. 3A, so that the cost of the illumination device 10 (FIG. 2) can be reduced. However, according to the configuration of the pixel 16 shown in FIG. 3B, the color reproducibility of the illumination light 51 emitted from the pixel 16 is inferior to the configuration shown in FIG. 3A.
[0056]
FIG. 3C shows still another example of the configuration of one pixel 16 of the lighting device 10. In FIG. 3C, the same components as those shown in FIG. 3A are denoted by the same reference numerals, and the description thereof is omitted. In the example shown in FIG. 3C, the pixel 16 includes one LED 17B. A white phosphor 18W is applied so as to cover the LED 17B. The white phosphor 18W emits white fluorescent light 61W when illuminated with blue light emitted from the LED 17B. The fluorescence 61W constitutes the illumination light 51 emitted from the pixel 16. According to the configuration of the pixel 16 shown in FIG. 3C, the brightness of the illumination light 51 emitted from the pixel 16 can be changed, but the color of the illumination light 51 cannot be changed. However, according to the configuration of the pixel 16 illustrated in FIG. 3C, the cost of the illumination device 10 (FIG. 2) can be reduced as compared with the configuration illustrated in FIGS. 3A and 3B. The configuration of the pixel 16 shown in FIG. 3C can be suitably employed for applications that do not require the color of the illumination light 51 to be changed.
[0057]
In addition, the structure of the pixel contained in the illuminating device 10 is not limited to the structure shown by FIG. 3A-FIG. 3C. An organic EL light emitting element or a plasma light emitting element may be used instead of the LED of a plurality of pixels. Further, the lighting device 10 may further control a conventional fluorescent lamp and / or incandescent lamp in addition to the plurality of pixels 16 that can be controlled independently. The illuminating device 10 may perform, for example, the overall illumination of the room with a fluorescent lamp and the local illumination with a plurality of pixels 16 that can be controlled independently.
[0058]
FIG. 4 shows a state in which the lighting device 10 is disposed in the home 102. In the example shown in FIG. 4, the lighting device 10 is attached to the wall surface of the room where the user 301 lives. Or the illuminating device 10 may be attached to the position 10a of the ceiling of the room.
[0059]
FIG. 5 shows the procedure of the lighting service provision process executed by the CPU 2 of the service center 1.
[0060]
Step ST1: A lighting service order (order 121) is received. For example, the order 121 is transmitted from the PC 104 in the home 102 via the home LAN 103 and the network 101 by the user 301 (FIG. 1). The transmitted order 121 is received by the network communication unit 3.
[0061]
The order 121 includes designation of the type of lighting service, for example. Types of lighting services include, for example, “message display service” and “lighting pattern display service”. In the following description, it is assumed that there are two types of lighting service, “message display service” and “lighting pattern display service”, unless otherwise specified.
[0062]
The order 121 is made by designating a lighting device (transmission destination lighting device) for displaying a message or a lighting pattern. The designation of the lighting device is performed by an address assigned to the lighting device, for example.
[0063]
When the user 301 designates “message display service” as the type of lighting service, the user 301 designates a fixed message and a user message displayed on the lighting device. Here, the fixed message is a message selected by the user 301 from the fixed sentences prepared in advance by the service center 1. A user message is an arbitrary message created by the user 301.
[0064]
When the user 301 specifies “lighting pattern display service” as the type of lighting service, the lighting pattern to be displayed on the lighting device is specified from the lighting patterns prepared in advance by the service center 1.
[0065]
The user 301 can transmit the order 121 using, for example, a web page described later with reference to FIGS. 6A to 6H. Such a web page is provided by the service center 1.
[0066]
Step ST2: It is determined whether or not the type of lighting service included in the order 121 is “message display service”. If the result of the determination in step ST2 is “Yes”, the process proceeds to step ST5. When the result of the determination in step ST2 is “No”, the process proceeds to step ST3.
[0067]
Step ST3: The illumination control data 131 for acquiring the designated illumination pattern is read out from the memory 4 (database) (FIG. 1), thereby obtaining the illumination control data 131. Here, the reading of the lighting control data 131 may be performed in consideration of the model name of the lighting fixture that should display the lighting pattern. Thereby, even when the shape and size of the display surface are different for each model name of the illumination device, the illumination control data 131 suitable for each illumination device is read. In this case, the lighting service order 121 received in step ST1 may include designation of the type name of the lighting fixture.
[0068]
Step ST4: The lighting control data 131 is transmitted to the destination lighting device included in the lighting service order 121 received in step ST1. The transmitted lighting control data 131 is received by the lighting device 10 via the network 101 and the home LAN 103 (FIG. 1).
[0069]
In this example, the illumination control data 131 is provided to the illumination device 10 by being transmitted directly to the illumination device 10 (without passing through a device other than the illumination device). However, the lighting control data 131 may be provided to the lighting device 10 by being indirectly transmitted to the destination lighting device. For example, the lighting control data 131 may be transmitted to the PC 104 placed in the home 102. The lighting control data 131 received by the PC 104 is transferred to the lighting device 10 automatically or manually by the user 301 at an appropriate timing. Further, the lighting control data 131 may be transmitted to the mobile phone (including PHS) of the user 301. The illumination control data 131 received by the mobile phone can be transferred to the illumination device 10 by wireless communication, for example.
[0070]
Step ST5: The illumination control data 131 is acquired by creating the illumination control data 131 so that the standard message and the user message are displayed on the display surface of the illumination device. The creation of the illumination control data 131 may be performed in consideration of the model name of the luminaire that should display the illumination pattern. Thereby, even when the shape and size of the display surface are different for each type of illumination device, illumination control data 131 suitable for each illumination device is created.
[0071]
The above-described step ST3 or step ST5 functions as a step of acquiring the lighting control data 131 for controlling the plurality of pixels 16 included in the lighting device 10 in accordance with the lighting service order 121.
[0072]
As the user interface when the user 301 transmits the order 121 (FIG. 1) to the service center 1, any user interface can be used. However, considering ease of access, it is preferable to use a web page on the world wide web as the user interface.
[0073]
FIG. 6A shows an example of a web page 601 that functions as a user interface when the user 301 transmits an order 121 to the service center 1.
[0074]
The web page 601 is described in an arbitrary page description language (for example, HTML language). A file describing the web page 601 is stored in the memory 4 of the service center 1. This file has a URL address that uniquely identifies the location where this file is stored on the network 101. When the user 301 inputs this URL address to the web page browsing software executed on the PC 104, the web page 601 is displayed on the PC 104.
[0075]
Web page 601 includes buttons 602-604. The user 301 selects each of an “introduction of lighting service” button 602, a “list of available lighting fixtures” button 603, and a “lighting service search” button 604 (for example, the mouse pointer 605 is positioned at each button position). In this state, by clicking a mouse button connected to the PC 104), a web page having contents corresponding to each button is displayed on the PC 104.
[0076]
FIG. 6B shows an example of a web page 610 for an introduction to lighting services. The web page 610 is displayed on the PC 104 when the user 301 selects the “Introduction of Lighting Service” button 602 on the web page 601 shown in FIG. 6A, for example.
[0077]
Web page 610 includes a “message display service list” button 611 and an “illumination pattern display service list” button 612.
[0078]
FIG. 6C shows an example of a web page 620 that displays a list of message display services. The web page 620 is displayed on the PC 104 when the user 301 selects the “message display service list” button 611 on the web page 610 shown in FIG. 6B, for example.
[0079]
FIG. 6C shows the message display service provided by the service center 1 such as a “birthday celebration” message, a “wedding celebration” message, an “entry / commercial celebration” message, and an “other” message displayed on the lighting device. Indicates that there is a service.
[0080]
FIG. 6D shows an example of a web page 630 for the user 301 to order a service for displaying a “birthday celebration” message to the service center 1. The web page 630 is displayed on the PC 104 when the user 301 selects the “birthday celebration” button 621 on the web page 620 shown in FIG. 6C, for example.
[0081]
Web page 630 includes areas 631 to 641 and a send button 642. When the user 301 inputs necessary information in each of the areas 631 to 641 and selects the transmission button 642, the order 121 is transmitted to the service center 1. Thereby, the lighting service provision process shown in FIG. 5 is started.
[0082]
In the region 631, for example, an IP address assigned to the lighting device is input as an address for specifying the lighting device that the user 301 desires to display a message. In an area 631, an address of an arbitrary device (for example, the PC 104 of the user 301) that is a transmission destination of the lighting control data 131 may be input.
[0083]
In the area 632, the model name of the lighting device is input. However, the address input to the area 631 is the address of the lighting device, and the service center 1 has a database describing the correspondence between the address of the lighting device and the model name of the lighting fixture, or the service is stored in such a database. If the center 1 can access, the input of the type name of the lighting device in the area 632 may be omitted. This is because the type name of the lighting fixture can be obtained using the address of the lighting device input in the region 631 and its database.
[0084]
The area 633 and the area 634 are alternatively selected from the standard message “HAPPY BIRTHDAY” and the standard message “Happy Birthday!” Depending on which user 301 prefers. In the example shown in FIG. 6D, the number of regular messages is 2, but this number may be increased. By increasing the number of fixed messages, the options of the user 301 can be increased.
[0085]
In the area 635, a user message is input.
[0086]
The areas 636 to 640 are used to specify the date and time when the lighting service is provided, that is, the date and time when the specified message is displayed on the lighting device 10. Such a display provides the lighting control data 131 to the lighting device 10 at the date and time designated by the service center 1, and the lighting device 10 that has received the lighting control data 131 immediately sends a message based on the lighting control data 131. It may be realized by a display method (method {circle around (1)}). Alternatively, the service center 1 immediately provides the lighting control data 131 to the lighting device 10 after the lighting control data 131 is acquired, and the lighting control data 131 is stored in the lighting control data 131 at the designated date and time when the lighting device 10 that received the lighting control data 131 is specified. It may be realized by a method of displaying a message based on the method (method {circle around (2)}). In this case, information indicating the date and time when the message is displayed is provided from the service center 1 to the lighting apparatus 10 together with the lighting control data 131. When the transmission destination of the illumination control data 131 is not a lighting device, method (2) is used.
[0087]
The user 301 inputs the date and time when the lighting service is provided in the areas 636 to 640 so that the lighting service is provided at a desired time on a desired day (for example, the birthday of the user 301's family). An order for lighting services can be made.
[0088]
When the input to the areas 636 to 640 is omitted, the service center 1 transmits the lighting control data 131 to the lighting device 10 immediately after the lighting control data 131 is acquired, and receives the lighting control data 131. The apparatus 10 immediately displays a message based on the illumination control data 131. Therefore, the message is displayed on the lighting device 10 immediately after the order 121 is transmitted.
[0089]
In the area 641, the bank account number of the user 301 is input. The bank account specified here is charged for the lighting service.
[0090]
FIG. 6E shows an example of a web page 645 that displays a list of lighting pattern display services. The web page 645 is displayed on the PC 104 when the user 301 selects the “lighting pattern display service list” button 612 on the web page 610 shown in FIG. 6B, for example.
[0091]
FIG. 6E shows that as a lighting pattern display service provided by the service center 1, there is a service for displaying lighting patterns of “situation lighting”, “relaxation lighting”, and “others” on the lighting device.
[0092]
FIG. 6F shows an example of a web page 650 that displays a list of lighting patterns of “situation lighting”. The web page 650 is displayed on the PC 104 when the user 301 selects the “situation lighting” button 646 in the web page 645 shown in FIG. 6E, for example.
[0093]
FIG. 6F shows that the lighting pattern of “situation lighting” includes lighting patterns with the theme of “season”, “nature”, “world famous tourist destination”, and “emotion”.
[0094]
FIG. 6G shows an example of a web page 660 that displays a list of lighting patterns with the theme of “nature”. The web page 660 is displayed on the PC 104 when the user 301 selects the “natural” button 651 in the web page 650 shown in FIG. 6F, for example.
[0095]
The illumination pattern having “nature” as a theme is an illumination pattern that reminds the user 301 of nature when the illumination pattern is displayed on the illumination device.
[0096]
FIG. 6G shows that there is an illumination pattern with the theme of “sea”, “river”, “mountain”, and “meadow” as an illumination pattern with the theme of “nature”.
[0097]
FIG. 6H shows an example of a web page 670 for the user 301 to order a lighting service on the theme of “grass” from the service center 1. The web page 670 is displayed on the PC 104 when, for example, the user 301 selects the “meadow” button 661 on the web page 660 shown in FIG. 6G.
[0098]
Web page 670 includes regions 631, 632, 636 to 641 and a send button 642. Since these areas and buttons are the same as the areas and buttons having the same reference numbers shown in FIG. 6D, description thereof is omitted.
[0099]
By using the web page shown in FIGS. 6A to 6H as a user interface when the user 301 sends an order for the lighting service to the service center 1, the user 301 can connect to the Internet. An order for lighting services can be transmitted from the terminal. The user 301 can also place an order to provide the lighting control data 131 to the lighting device 10 placed in another person's home. Further, it is possible to place an order from the outside so as to provide the lighting control data 131 to the lighting device 10 placed at home.
[0100]
FIG. 7A shows an example of the structure of the illumination control data 131. In the example shown in FIG. 7A, luminance data is designated for each of pixel designation data # 1 to pixel designation data #n. Each of the pixel designation data # 1 to pixel designation data #n corresponds to one of the pixels 16 included in the display unit 14 of the illumination device 10 (FIG. 2). Hereinafter, for the sake of explanation, it is assumed that each of the pixels 16 has the structure shown in FIG. 3A.
[0101]
Each of the pixel designation data # 1 to pixel designation data #n designates a corresponding pixel based on, for example, the XY coordinates shown in FIG. For example, the pixel designation data corresponding to the pixel arranged at the upper left corner of the display surface shown in FIG. 2 is represented as (1, 1).
[0102]
The luminance data includes at least one list. Each of the lists is expressed as (start time, end time, R luminance, G luminance, B luminance). This list indicates that the luminance of the LEDs 17R, 17G, and 17B is set to “R luminance”, “G luminance”, and “B luminance” from “start time” to “end time”, respectively.
[0103]
The brightness of each of the LEDs 17R, 17G, and 17B can be represented by, for example, 256 levels of brightness levels from 0 to 255.
[0104]
FIG. 7B shows an example of the structure of luminance data for a specific pixel. In the example shown in FIG. 7B, time 0 to time t₁, The luminances of the LEDs 17R, 17G, and 17B included in the specific pixel are set to luminance levels of 0, 255, and 0, respectively, and the time t₁~ Time t₂During this time, the brightness of the LEDs 17R, 17G and 17B is set to the brightness levels of 255, 148 and 0, respectively, and the time t₂~ Time t_ThreeDuring the period, the luminances of the LEDs 17R, 17G, and 17B are set to the luminance levels of 255, 255, and 255, respectively.
[0105]
FIG. 7C shows how the brightness of the LEDs 17R, 17G, and 17B is controlled by the brightness data shown in FIG. 7B. When the luminance of the LEDs 17R, 17G, and 17B included in one pixel 16 is controlled as shown in FIG. 7C, the illumination light 51 emitted from the pixel 16 is transmitted from time 0 to time t.₁It looks green during the period. Also, time t₁~ Time t₂It looks orange during the time t₂~ Time t_ThreeIt looks white during the period. Of course, the luminance of the LEDs 17R, 17G, and 17B for expressing each color is not limited to the example shown in FIG. 7C. For example, the brightness of the LEDs 17R, 17G, and 17B is such that the sensitivity of the human eye (visibility characteristics) is such that the colors of “green”, “orange”, and “white” appear to be as bright as human eyes. May be adjusted in consideration of
[0106]
According to the illumination control data 131 shown in FIG. 7A, since the luminance data is designated for each of the plurality of pixels 16, the plurality of pixels can be controlled independently. Thus, the illumination control data 131 represents the illumination pattern displayed on the illumination device 10.
[0107]
The structure of the illumination control data 131 is not limited to the data structure shown in FIG. 7A. The illumination control data 131 may have an arbitrary data structure capable of independently controlling the plurality of pixels 16 included in the illumination device 10 (FIG. 2). The brightness level at which the LED included in each pixel is controlled is not limited to 256 levels.
[0108]
When the illumination pattern includes a pattern that repeats in time, each of the repeated patterns may be represented by common data. Thereby, the size of the illumination control data 131 can be reduced.
[0109]
The illumination control data 131 may have a data structure that does not depend on the configuration of the illumination device 10. For example, the illumination control data 131 depends on the number of pixels in the horizontal direction and the vertical direction of the display unit 14 of the illumination device 10 (for example, 1024 (horizontal) × 768 (vertical), 1280 (horizontal) × 768 (vertical), etc.). It may have a data structure that does not. In this case, the illumination control data 131 can be applied to the illumination device 10 having an arbitrary configuration. In this case, it goes without saying that the memory 4 of the service center 1 does not have to store the lighting control data 131 for each type of lighting device.
[0110]
Alternatively, the display control unit 13 may have a function of appropriately converting lighting control data for lighting devices having different configurations and displaying them on the display unit 14. For example, the display control unit 13 converts illumination control data for a lighting device having 1024 (horizontal) × 768 (vertical) pixels, and converts the illumination control data into a display unit 14 having 1280 (horizontal) × 768 (vertical) pixels. You may have the function to display. Such conversion can be, for example, enlargement or reduction using interpolation. Alternatively, such conversion may be a spatial repetition of the same pattern.
[0111]
FIG. 8 shows an example in which a message is displayed on the lighting device 10. In FIG. 8, a pixel indicated by white indicates a pixel 16 that emits white illumination light, and a pixel 16 indicated by hatching indicates a pixel that is turned off.
[0112]
On the display unit 14, a message “HAPPY BIRTHDAY Yoshiko” is displayed. Among these, “HAPPY BIRTHDAY” is a standard message, and “Yoshiko” is a user message.
[0113]
The message shown in FIG. 8 can be displayed on the lighting device 10 in accordance with the time of a birthday party held for a family member (for example, a daughter), for example. The birthday party participants are not informed that such a message is displayed on the lighting device 10. If such a message is displayed on the lighting device 10 at the time of the birthday party, it is expected that the participants of the birthday party will be surprised and excited. In this way, the lighting device 10 can achieve entertainment.
[0114]
Hereinafter, an example in which an illumination pattern is displayed on the illumination device 10 will be described with reference to FIGS. 9A, 9B, 10A, 10B, 11A, 11B, and 12. FIG. In the example shown below, the illumination device 10 displays an illumination pattern with the theme “grassland”. In this lighting pattern, the sunbeams in the grassland are reproduced by the lighting device 10.
[0115]
FIG. 9A is a diagram for explaining the principle of a sunbeam day. A light ray 907 emitted by the sun 903 reaches the ground 906 through the tree 905. At that time, a part of the light beam 907 is blocked by the leaf 904, and the light beam 907 a passing through the gap between the leaves 904 reaches the ground surface 906. The light beam 907a is called a sunbeam.
[0116]
FIG. 9B shows the ground 906 illuminated by the sunbeams. A bright area 909 exists on the ground 906 corresponding to one of the light rays 907a.
[0117]
FIG. 10A shows a state where the floor surface 1006 of the room is illuminated by the lighting device 10 attached to the ceiling.
[0118]
Each of the pixels 16 of the illumination device 10 emits illumination light 51. The illumination light 51 is set as close as possible to the color of the light beam 907 emitted by the sun. Each of the pixels 16 has a relatively high directivity. That is, one illumination light 51 illuminates a relatively narrow area of the floor surface 1006.
[0119]
Such high directivity can be realized by, for example, condensing light emitted from the LED included in the pixel 16 in a specific direction using a reflecting mirror or an optical fiber. Alternatively, in order to realize high directivity, a semiconductor laser may be used instead of the LED.
[0120]
FIG. 10B shows a state of the floor surface 1006 illuminated by the illumination light 51. Each of the circular regions 910 indicates a region on the floor surface illuminated by the illumination light 51 emitted from one of the plurality of pixels 16. Each of the regions 910 corresponds to each of the pixels 16 of the lighting device 10. A circle shown in white in FIG. 10B indicates that the corresponding pixel 16 is lit and the floor surface 1006 is illuminated by the illumination light 51 emitted from the pixel 16. A circle indicated by hatching in FIG. 10B indicates that the corresponding pixel 16 is turned off. That is, each circle shown in white in FIG. 10B indicates a bright region of the floor surface 1006.
[0121]
The plurality of pixels 16 included in the illumination device 10 are controlled so as to have the same positional relationship as each of the bright areas 909 shown in FIG. 9B. Thereby, the floor surface 1006 can be illuminated in the same form as the ground 906 illuminated by the sunbeams.
[0122]
In actual sunbeams, the bright area 909 on the ground 906 moves as shown by arrow 908 (FIG. 9B) in response to the leaves 904 swaying in the wind. Hereinafter, with reference to FIG. 11A, FIG. 11B, and FIG. 12, the example which implement | achieves such a movement with the illuminating device 10 is shown.
[0123]
FIG. 11A shows a region on the floor surface 1006 that is illuminated by two pixels included in the lighting device 10. In the example shown in FIG. 11A, the area 910-1 on the floor surface 1006 is illuminated by the pixel 16-1, and the area 910-2 on the floor surface 1006 is illuminated by the pixel 16-2.
[0124]
FIG. 11B shows an example of brightness control of the pixel 16-1 and the pixel 16-2. Each of the pixel 16-1 and the pixel 16-2 has a structure illustrated in FIG. 3A. The brightness of the pixel is derived from the luminance of the three LEDs included in the pixel.
[0125]
In the example shown in FIG. 11B, the brightness of the pixel 16-1 is the time t.₁~ T_ThreeBetween level 0 and level L₁Until the brightness of the pixel 16-2 increases₁~ T_ThreeLevel L during₁Gradually decreases from level 0 to level 0. That is, the illumination pattern is displayed on the illumination device 10 so that the brightness changes with the passage of time. When the brightness of the pixels 16-1 and 16-2 gradually increases or decreases, the brightness of the three LEDs included in each pixel is controlled so that the color of the illumination light of the pixel does not change. The
[0126]
FIG. 12 shows a change in the state of the floor surface 1006 when the brightness of the pixels 16-1 and 16-2 is controlled as shown in FIG. 11B.
[0127]
Time t₁Then, only the area 910-2 is illuminated by the pixel 16-2.
[0128]
Time t₂(T₁<T₂<T_Three), The area 910-1 and the area 910-2 are illuminated by the pixel 16-1 and the pixel 16-2, respectively. The luminance of each of the pixels 16-1 and 16-2 is the time t₁Is lower than the luminance of the pixel 16-2.
[0129]
Time t_ThreeThen, only the area 910-1 is illuminated by the pixel 16-1.
[0130]
When the illumination state of the area 910-1 and the area 910-2 changes in this way, the human eye sees the time t₁To time t_ThreeFrom the region 910-2 to the region 910-1, it is perceived that the bright region has moved. By applying this principle to each of the circles shown in white in FIG. 10B, it is possible to make the human eye perceive that the circle (bright area) shown in white is swaying. That is, the lighting device 10 realizes a movement like an actual sunbeam.
[0131]
By displaying such an illumination pattern on the illumination device 10, it is expected that the user 301 in the room illuminated by the illumination device 10 will feel refreshed and relaxed as if actually in the grassland. In this way, the lighting device 10 can achieve entertainment.
[0132]
It goes without saying that examples of illumination patterns are not limited to the examples described with reference to FIGS. 9A, 9B, 10A, 10B, 11A, 11B, and 12. FIG. For example, a landscape image may be displayed on the illumination device 10 as the illumination pattern.
[0133]
In addition, a message or an illumination pattern is displayed on the illumination device 10. These may be mixedly displayed on the lighting device 10. For example, the message may be displayed with the illumination pattern as the background, and the brightness and / or color of the pixels constituting the character of the message may change over time.
[0134]
(Embodiment 2)
FIG. 13 shows a configuration of a lighting system 3100 according to the second embodiment of the present invention. In FIG. 13, the same components as those shown in FIG. 1 are denoted by the same reference numerals, and the description thereof is omitted.

The home 102 is provided with a lighting system 3100 that can set a lighting form desired by a user in association with a predetermined condition. The lighting system 3100 includes n lighting devices 3010 and a lighting control device 3160 that controls the n lighting devices 3010. Here, n is an arbitrary integer of 2 or more. In the following description, in order to distinguish the n illumination devices 3010, they are referred to as illumination device # 1, illumination device # 2,..., Illumination device #n.
[0136]
In the following description, it is assumed that each of lighting devices # 1 to #n includes a plurality of independently controllable pixels. However, the present invention is not limited to this. It is only necessary that at least one of the lighting devices # 1 to #n placed in the home 102 includes a plurality of independently controllable pixels. The illumination control device 3160 can control one or more illumination devices 3010 including a plurality of pixels that can be controlled independently.
[0137]
The home 102 may further include devices (information home appliances) such as a personal computer (PC) 104, a television (TV) 105, and a microwave oven 106. These information home appliances, lighting devices # 1 to #n, and lighting control device 3160 are connected to each other via a home LAN 103 installed in the home 102. The home LAN 103 is connected to the network 101.
[0138]
Note that a home server (not shown) that generally controls information appliances connected to the home LAN 103 is placed in the home 102. The home server and the lighting control device 3160 may be separate devices, but it is preferable that the home server also serves as the lighting control device 3160. This is because the function of the lighting control device 3160 can be realized by a normal home server.
[0139]
FIG. 14 shows a configuration of the illumination control device 3160. The lighting control device 3160 includes a network communication unit 3161 connected to the home LAN 103, an input unit 3166 that allows a user to input user data to the lighting control device 3160, a memory 3165 that stores user data, and a user Processing for executing predetermined processing by controlling display unit 3164 for displaying data, timing unit 3163 for measuring time, network communication unit 3161, timing unit 3163, display unit 3164, memory 3165, and input unit 3166 Part 3162. The processing unit 3162 can be realized by a processor such as a CPU, for example.
[0140]
FIG. 15 shows a configuration of the lighting device 3010. Each of illumination devices # 1 to #n may have the configuration shown in FIG. In FIG. 15, the same components as those shown in FIG. 2 are denoted by the same reference numerals, and the description thereof is omitted.
[0141]
The illumination device 3010 includes a sensor 3012 for detecting a predetermined condition, and a processing unit 3011 that executes a predetermined process by controlling the network communication unit 11, the memory 12, the display control unit 13, and the sensor 3012. . The processing unit 3011 can be realized by a processor such as a CPU, for example.
[0142]
The sensor 3012 may be a sensor (for example, a pyroelectric infrared sensor) that detects that someone (whether a specific person or an unspecified person) is in the room where the lighting device 3010 is installed. In addition, a sensor (for example, a biometric sensor) that detects that a specific person is present in the room where the lighting device 3010 is installed may be used.
[0143]
Alternatively, instead of providing the sensor 3012 incorporated in the illumination device 3010 or in addition to providing the sensor 3012 incorporated in the illumination device 3010, the reading device is associated with at least one of the illumination devices # 1 to #n. 3020 may be provided.
[0144]
FIG. 22 shows an example in which a reading device 3020 is installed in association with the illumination device # 1. The reading device 3020 is connected to the home LAN 103 (FIG. 13). The output of the reading device 3020 is provided to the lighting control device 3160 via the home LAN 103.
[0145]
For example, it is assumed that an electronic tag (non-contact type IC chip) for notifying the user's location is embedded in clothes and the user wears the clothes with the electronic tag. As the electronic tag, for example, a known RF-ID tag can be suitably used. The reading device 3020 uses a wireless technology to detect a user name stored in the storage unit of the electronic tag, thereby detecting a specific person (or unspecified) in a space (for example, a bedroom) where the lighting device # 1 is installed. It is possible to determine whether or not there is a person.
[0146]
When the user always carries the mobile device 3030 (such as a mobile phone), the user notifies the reader 3020 of his / her location using the mobile device 3030, so that the reader 3020 is installed by the lighting device # 1. It is possible to determine whether or not there is a specific person (or an unspecified person) in the created space (for example, a bedroom).
[0147]
As described above, the reading device 3020 functions as a human detection device that detects that a person (whether a specific person or an unspecified person) is in a space where at least one illumination device is installed. Alternatively, the reading device 3020 can function as a specific person detection device that detects that a specific person is present in a space in which at least one illumination device is installed.
[0148]
Note that in the user data 3170, which will be described later, when a condition regarding whether or not a person (a specific person or an unspecified person) exists in the room is not set, the sensor 3012 and the reading device 3020 built in the lighting device 3010 are It can be omitted.
[0149]
FIG. 16 shows the structure of user data 3170 stored in the memory 3165 of the lighting control device 3160 shown in FIG. When the user inputs user data 3170 to the lighting control device 3160 by operating the input unit 3166 (eg, a keyboard or a mouse), the input user data 3170 is stored in the memory 3165.
[0150]
User data 3170 includes condition specifying information 3177, lighting pattern specifying information 3178, and lighting device specifying information 3179. User data 3170 may further include user specifying information 3176.
[0151]
The condition specifying information 3177 is information for specifying a condition. The conditions specified by the condition specifying information 3176 are: (1) a condition for designating the time (or time zone) at which the illumination pattern should be displayed on the illumination device; and (2) a space (for example, a room) where the illumination device is installed. Any one of the conditions for designating that there is a person (a specific person or an unspecified person), and (3) the conditions for designating that there is a specific person in a space (for example, a room) where the lighting device is installed Or any combination of the conditions (1) to (3).
[0152]
The illumination pattern specifying information 3178 is information for specifying an illumination pattern to be displayed on one or more lighting devices 3010 when the condition specified by the condition specifying information 3177 is satisfied. The illumination pattern specified by the illumination pattern specifying information 3178 includes (1) an illumination pattern for displaying time, (2) an illumination pattern for displaying a message, and (3) an illumination pattern for adjusting a user's mood. Or any combination of illumination patterns (1) to (3).
[0153]
The lighting device specifying information 3179 is information for specifying one or more lighting devices 3010 that should display the lighting pattern specified by the lighting pattern specifying information 3178 when the condition specified by the condition specifying information 3177 is satisfied. .
[0154]
Thus, when the condition specified by the condition specifying information 3177 is established, “what” is specified by the illumination pattern specifying information 3178, and “where” is displayed by the lighting device specifying information 3179. Identified.
[0155]
The user specifying information 3176 is information for specifying the user who has input the user data 3170 to the lighting control device 3160.
[0156]
FIG. 16 shows a state in which five user data 3171, 3172, 3173, 3174, 3175 are stored in the memory 3165 as an example of the user data 3170.
[0157]
Here, as a home model, it is assumed that a family of three (Father A, Mother B, and Child C) lives in the home 102, and that the home 102 has four rooms shown in FIG. As shown in FIG. 17, lighting device # 1 is installed in the bedrooms of Mr. A and B, lighting device # 2 is installed in the bedroom of Mr. C, and lighting device # 3 is installed in the living room. Is installed, and lighting device # 4 is installed in the cafeteria.
[0158]
The user data 3171 indicates that Mr. A has set an instruction “When 7:30 am every day, display the lighting pattern“ alarm # 1 ”on the lighting devices # 1 and # 2 in the bedroom”. . As the illumination pattern of “alarm # 1”, for example, an illumination pattern that gradually increases (brightens) the illumination brightness can be used.
[0159]
The user data 3172 indicates that Mr. B has set an instruction “When every week from Monday to Friday at 8:00 am, display the lighting pattern“ School attendance # 3 ”on the lighting device # 4 of the dining room”. As the lighting pattern of “School attendance # 3”, for example, an illumination pattern that displays a message “Mr. C, school attendance time” may be used, or a lighting pattern (moving image) of a march style that has a good tempo may be used. Also good.
[0160]
The user data 3173 indicates that “if someone is in a room with lighting device # 3 (ie, living room) every Friday from 8 to 10 pm, the lighting pattern“ healing # 2 ”is displayed in the living room lighting device #. It is shown that the instruction “display on 3” is set by Mr. A. As the illumination pattern “healing # 2”, for example, an illumination pattern representing “sunlight through the sun” described with reference to FIGS. 9A to 12 can be used.
[0161]
User data 3174 indicates that Mr. A has set an instruction to “display an illumination pattern“ sleep # 5 ”on the lighting device in the room where Mr. C is present at 10:00 pm every day”. For example, an illumination pattern “rest # 5” may be an illumination pattern that displays a message “Now it ’s time for a break. Mr. C”. As shown in FIG. An illumination pattern in which the luminance is lowered (darkened) may be used.
[0162]
Here, “*” set in the illumination device specifying information 3179 indicates that the illumination device that should display the illumination pattern “sleep # 5” is undecided. In this case, the lighting pattern of “rest # 5” is displayed on the lighting device # 3 in the living room when C is in the living room at 10:00 pm, and when C is in the bedroom at 10:00 pm. It will be displayed on the lighting device # 1 in the bedroom. Thus, when “*” is set in the lighting device specifying information 3179, it is necessary to specify the place where Mr. C is present before displaying the lighting pattern. The location can be specified based on, for example, the output of the sensor 3012 incorporated in the lighting device 3010 or the output of the reading device 3020.
[0163]
The user data 3175 indicates that Mr. C has set an instruction to “display the lighting pattern“ Message # 1 ”on the lighting device in the room where Mr. B” exists. As the illumination pattern “Message # 1”, for example, an illumination pattern that displays a message “I'm sorry, mom” can be used. Such a message is effective when the child C wants to apologize to the mother B secretly. “Message # 1” may be a standard message or an atypical message created by the user.
[0164]
Here, “*” set in the illumination device specifying information 3179 indicates that the illumination device that should display the illumination pattern “message # 1” is undecided. In this case, the lighting pattern “Message # 1” is displayed on the lighting device # 3 in the living room when Mr. B is in the living room, and on the lighting device # 1 in the bedroom when Mr. B is in the bedroom. Will be displayed. Thus, when “*” is set in the lighting device specifying information 3179, it is necessary to specify the location where Mr. B is present before displaying the lighting pattern. The location can be specified based on, for example, the output of the sensor 3012 incorporated in the lighting device 3010 or the output of the reading device 3020.
[0165]
Note that the user data 3170 can be freely created by the user. Accordingly, the user can freely select and set the illumination pattern, time, and illumination device. As a result, it is possible to create enjoyment that only the user can know. For example, the lighting device 3010 can be used as a secret clock that only a user can understand. For example, user data 3170 is created so that a predetermined illumination pattern (for example, an illumination pattern that flashes with a specific color) is displayed on the illumination device 3010 every time a predetermined time (for example, 3 hours) elapses. The lighting device 3010 can be used as a secret clock. Alternatively, by creating user data 3170 so that an illumination pattern in which three bubbles appear at 3 o'clock is displayed on the illumination device 3010, the illumination device 3010 may be used as a secret clock. . In this way, when the user creats the user data 3170, it is possible to realize lighting with high entertainment properties.
[0166]
Note that the user need only set the user data 3170 in the lighting control device 3160 that controls the plurality of lighting devices 3010, and does not need to set each of the plurality of lighting devices 3010 individually. Thereby, the user can easily set to display various illumination patterns on each of the plurality of illumination devices.
[0167]
Note that data representing the illumination pattern specified by the illumination pattern specifying information 3178 (content of the illumination pattern) may be stored in the memory 3165 in the illumination control device 3160 or stored in the memory 12 in the illumination device 3010. May be.
[0168]
When data representing the illumination pattern specified by the illumination pattern specifying information 3178 (content of illumination pattern) is stored in the memory 3165 in the illumination control device 3160, the illumination pattern is displayed on the illumination device 3010. The illumination pattern specifying information 3178 including data representing the illumination pattern (content of illumination pattern) needs to be transmitted from the illumination control device 3160 to the illumination device 3010.
[0169]
When data representing the illumination pattern specified by the illumination pattern specifying information 3178 (content of the illumination pattern) is stored in the memory 12 in the illumination device 3010, in order to display the illumination pattern on the illumination device 3010, It is necessary to transmit illumination pattern specifying information 3178 including an identifier for identifying the illumination pattern from the illumination control device 3160 to the illumination device 3010.
[0170]
Data representing the lighting pattern (contents of the lighting pattern) may be created by the user himself / herself, or may be obtained from the service center 1 using the lighting service described in the first embodiment. In any case, the data representing the illumination pattern (the illumination pattern content) is stored in the memory 3165 in the illumination control device 3160 or the memory 12 in the illumination device 3010 before executing the processing shown in FIG. It is necessary to store in.
[0171]
Whether an identifier for identifying the illumination pattern is transmitted from the illumination control device 3160 to the illumination device 3010, and data representing the illumination pattern corresponding to the identifier (illumination pattern content) is stored in the memory 12 in the illumination device 3010. Only when it is determined as “No”, data representing the illumination pattern (contents of the illumination pattern) may be transmitted from the illumination control device 3160 to the illumination device 3010. Thereby, the amount of data to be transmitted from the illumination control device 3160 to the illumination device 3010 can be reduced.
[0172]
Note that an input interface (for example, an input screen displayed on the display unit 3164) used for the user to input the user data 3170 to the lighting control device 3160 is easily designed to conform to the format of the user data 3170. Can be done. For example, as an example of an input interface used for inputting the condition specifying information 3177, the condition (1) (condition for designating the time (or time zone) at which the illumination pattern should be displayed on the illumination device) is input. And an input area for inputting a condition (2) (a condition for designating that there is a person (a specific person or an unspecified person) in a space (for example, a room) where a lighting device is installed) An input screen including an input area for inputting condition (3) (a condition for designating that a specific person is in a space (for example, a room) in which a lighting device is installed) can be used. For example, in order to input the condition specifying information 3177 corresponding to the user data 3171, “7:30 am every day” is input in the input area for inputting the condition (1), and the condition (2) is input. “−” May be input to the input area of “” and “−” may be input to the input area for inputting the condition (3). Here, inputting “-” indicates that a condition corresponding to the input area is not set.
[0173]
As a method for designating the time (or time zone) at which the illumination pattern of condition (1) is to be displayed on the illumination device, any method used for setting the time (or time zone) of a known timer or the like is used. Can be employed. The time (or time zone) may be the time (time zone) of a specific day (for example, x month x day, birthday, wedding anniversary, etc.), or several minutes (every day, every day) The time (or time zone) may be Friday, Saturday, Sunday, weekday, the second Sunday of every month, or the first week of March. As a method for designating such a day, an arbitrary method used in a known video recording reservation or the like can be adopted.
[0174]
It is possible to display the above-described illumination pattern in accordance with music. In this way, when the lighting pattern and music are used in combination, it is possible to work on vision and hearing simultaneously, which is more effective.
[0175]
FIG. 19 shows a procedure of processing executed on the side of the lighting control device 3160 in order to provide a lighting form desired by the user in association with a predetermined condition. The processing procedure shown in FIG. 19 can be stored in the memory 3165 in the form of a program, for example. The processing unit 3165 executes this program every predetermined time (for example, 10 msec).
[0176]
Step ST3181: The processing unit 3162 determines, for each user data 3170 stored in the memory 3165, whether a condition specified by the condition specifying information 3177 is satisfied. As described above, the processing unit 3162 functions as a determination unit that determines whether or not the condition specified by the condition specifying information 3177 is satisfied.
[0177]
For example, when the condition specified by the condition specifying information 3177 includes the condition (1) (condition for designating the time (or time zone) when the illumination pattern should be displayed on the lighting device), the processing unit 3162 It is determined whether or not the condition specified by the condition specifying information 3177 is satisfied by comparing the current time measured by the unit 3163 and the time (or time zone) specified by the condition (1). . For example, the condition specified by the condition specifying information 3177 is condition (2) (a condition for designating that there is a person (a specific person or an unspecified person) in a space (for example, a room) where the lighting device is installed). Alternatively, in the case of including the condition (3) (a condition for designating that there is a specific person in a space (for example, a room) in which the lighting device is installed), the processing unit 3162 includes the sensor 3012 incorporated in the lighting device 3010. Or the output of the reading device 3020 determines whether or not the condition specified by the condition specifying information 3177 is satisfied.
[0178]
If the determination result in step ST3181 is “Yes”, the process proceeds to step ST3182. If the determination result in step ST3181 is “No”, the process ends.
[0179]
Step ST3182: The processing unit 3162 refers to the illumination device specifying information 3179 corresponding to the established condition, and thereby displays one or more illuminations that should display the illumination pattern specified by the illumination pattern specifying information 3178 corresponding to the established condition. Device 3010 is identified.
[0180]
When “*” indicating that “the lighting device 3010 to display the lighting pattern specified by the lighting pattern specifying information 3178 is undecided” is set in the lighting device specifying information 3179 corresponding to the established condition. Includes one or more illumination devices 3010 installed in a place where the corresponding person is present as “one or more illumination devices 3010 to display the illumination pattern specified by the illumination device identification information 3178 corresponding to the established condition”. Identified.
[0181]
Step ST3183: The processing unit 3162 controls the network communication unit 3161 to transmit the illumination pattern specifying information 3178 to one or more lighting devices 3010 specified in step ST3182. Of course, the processing unit 3162 may generate transmission data including the illumination pattern specifying information 3178 and control the network communication unit 3161 to transmit the transmission data. For example, the transmission data includes a header part and a data part including illumination pattern specifying information 3178. The header portion includes identification information for identifying at least one lighting device 3010 that transmits transmission data. In the example illustrated in FIG. 17, the identification information is configured to be able to identify four illumination devices # 1 to # 4. In this case, the identification information can be expressed by, for example, 2-bit data. The network communication part 3161 functions as a transmission part which transmits the illumination pattern specific information 3178 to the one or more illumination devices 3010 identified in step ST3182.
[0182]
Transmission data transmitted by the network transmission unit 3161 is received by the network communication unit 11 via the home LAN 103. As described above, the network communication unit 11 functions as a reception unit that receives transmission data including the illumination pattern specifying information 3178 transmitted from the illumination control device 3160.
[0183]
FIG. 20 shows a procedure of processing executed on the side of the lighting device 3010 in order to provide a lighting form desired by the user in association with a predetermined condition. The processing procedure shown in FIG. 20 can be stored in the memory 12 in the form of a program, for example. The processing unit 3011 executes this program every predetermined time (for example, 10 msec). Alternatively, the processing unit 3011 may be activated only when the network communication unit 11 receives transmission data from the lighting control device 3160, and the activated processing unit 3011 may execute this program.
[0184]
Step ST3191: The processing unit 3011 determines whether or not the network communication unit 11 has received transmission data including the illumination pattern specifying information 3178 from the illumination control device 3160. The transmission data received by the network communication unit 11 is output to the processing unit 3011.
[0185]
If the determination result in step ST3191 is “Yes”, the process proceeds to step ST3192. If the determination result in step ST3191 is “No”, the process ends.
[0186]
Step ST3192: The processing unit 3011 interrupts the processing in the current state mode (first state mode), and determines the lighting pattern specified by the lighting pattern specifying information 3178 for the current state mode (first state mode). Transition to the state mode to be displayed (second state mode).
[0187]
Step ST3193: The processing unit 3011 controls the display control unit 13 so that the illumination pattern specified by the illumination pattern specifying information 3178 is displayed on the display unit 14.
[0188]
Step ST3194: The processing unit 3011 determines whether or not the display of the illumination pattern specified by the illumination pattern specifying information 3178 has ended. Such an end determination may be made, for example, by determining whether or not a predetermined time has elapsed for each illumination pattern, or by detecting that the same illumination pattern has continued for several seconds. May be made.
[0189]
If the determination result in step ST3194 is “Yes”, the process proceeds to step ST3195. If the determination result in step ST3194 is “No”, the process returns to step ST3194.
[0190]
Step ST3195: The processing unit 3011 returns the state mode (second state mode) for displaying the illumination pattern specified by the illumination pattern specifying information 3178 to the previous state mode (first state mode), and the previous state The process suspended in the mode (first state mode) is resumed.
[0191]
FIG. 21 schematically shows state mode transitions in the lighting device 3010. The lighting device 3010 has three state modes (“low power mode”, “normal lighting mode”, and “illumination pattern display mode”). The “low power mode” is a state mode that operates with lower power consumption than the “normal lighting mode”, and is a state mode that is used during standby. The “normal lighting mode” is a state mode in which lighting is performed with a single color (usually white). The “illumination pattern display mode” is a state mode in which the illumination pattern specified by the illumination pattern specification information 3178 is displayed.
[0192]
As shown in FIG. 21, the three state modes can transition to each other. Such state mode transition is managed by the processing unit 3011. That is, the processing unit 3011 functions as a state management unit that manages the transition of a plurality of state modes.
[0193]
The “current state mode” when the processing unit 3011 receives the transmission data including the illumination pattern specifying information 3178 from the illumination control device 3160 is “low power mode”, “normal lighting mode”, and “illumination pattern display mode”. Either can be.
[0194]
When the “current state mode” at the time when the transmission data is received is the “low power mode”, the processing unit 3011 performs the “first mode” = “low power mode” described with reference to FIG. To execute the process. In this case, in order to resume the processing interrupted in the “low power mode”, the fact that the state mode at the time of interruption is “low power mode” is stored in the memory 12 and stored in the memory 12 at the time of return. The state mode may be referred to.
[0195]
When the “current state mode” when the transmission data is received is the “normal lighting mode”, the processing unit 3011 selects “first mode” = “normal lighting mode” described with reference to FIG. To execute the process. In this case, in order to resume the process interrupted in the “normal lighting mode”, the state mode at the time of interruption is stored in the memory 12 and stored in the memory 12 at the time of return. The state mode may be referred to.
[0196]
When the “current state mode” when the transmission data is received is the “illumination pattern display mode”, the processing unit 3011 selects “the first mode” = “illumination pattern” described with reference to FIG. The process is executed as “display mode”. In this case, in order to resume the process interrupted in the “illumination pattern display mode”, the state mode at the time of interruption is “illumination pattern display mode” and the return address of the illumination pattern display program whose execution has been interrupted. The state mode stored in the memory 12 may be referred to, and the state mode stored in the memory 12 at the time of return may be referred to, and the execution of the illumination pattern display program may be restarted from the return address.
[0197]
In the above-described embodiment, the example in which the state management unit manages the transition of the three state modes has been described. However, the number of state modes to be managed is not limited to three. The number of state modes to be managed may be any number greater than or equal to three. For example, the present invention can be similarly applied even when the illumination device 3010 has two state modes of “normal lighting mode” and “illumination pattern display mode”.
[0198]
As described above, the state management unit (processing unit 3011) returns to the original state after the display processing of the illumination pattern generated in an interrupted manner in response to the reception of the transmission data including the illumination pattern specifying information 3178 is completed. Manage transitions of multiple state modes to automatically return to mode. This is convenient because it is not necessary for the user to instruct to change the state mode.
[0199]
However, when the current state mode when the transmission data including the illumination pattern specifying information 3178 is received is the “illumination pattern display mode”, the state management unit (processing unit 3011) is not necessarily in the current state mode. It is not necessary to interrupt the process. For example, the received illumination pattern specifying information 3178 may be ignored, or the received illumination pattern specifying information 3178 is temporarily stored in the memory 12 and received after the processing in the current state mode is completed. Display processing based on the illumination pattern specifying information 3178 may be performed.
[0200]
In Embodiment 2 described above, the example in which each of the plurality of lighting devices 3010 placed in the home 102 includes a plurality of independently controllable pixels is described, but the present invention is not limited to this. . The lighting control device 3160 may control a single lighting device 3010 including a plurality of pixels that can be controlled independently. In this case, the transmission destination of the illumination pattern specifying information is always fixed to the single lighting device 3010, so that the user does not need to set the lighting device specifying information in the lighting control device 3160.
[0201]
The scent of the room illuminated by the lighting device changes as the pattern displayed on the lighting device (the lighting device 10 or the lighting device 3010) described in Embodiment 1 or 2 changes with time. You may make it do.
[0202]

[0204]
When the lighting device includes the scent control device 1300, the lighting control data provided to the lighting device includes data for controlling the motor 1302. The lid 1303 opens and closes when the motor 1302 operates. When the lid 1303 is opened, the scent emitted by the perfume 1304 is filled in the room where the lighting device is placed. The intensity of the scent is controlled by adjusting the amount by which the lid 1303 opens.
[0205]
By controlling the scent of the room in accordance with the temporal change of the lighting pattern, the user 301 can be made more refreshing or more relaxed. This makes it possible to achieve higher entertainment properties.
[0206]
Note that in the example shown in FIG. 23, the lighting device can control one scent type, but by using a plurality of scent control devices 1300 having different types of perfume 1304, a plurality of lighting devices can be used. The scent can be controlled. In addition, since a plurality of scents can be mixed by simultaneously opening the lids 1303 of the plurality of scent control devices 1300, many types of scents can be realized, and higher entertainment properties can be realized.
[0207]
The lighting pattern displayed on the lighting device (the lighting device 10 or the lighting device 3010) described in the first embodiment or the second embodiment is linked to, for example, music and / or video provided by a broadcast or a recording medium. It may be changed.
[0208]
