Detailed Implementation

[0025] Hereinafter, preferred embodiments of the present disclosure will be described with reference to the accompanying drawings. Furthermore, the dimensions and scales of the parts in the drawings may differ slightly from actual dimensions, and some parts are shown schematically for ease of understanding. Moreover, unless otherwise specified in the following description, the scope of the present disclosure is not limited to these embodiments.

[0026] 1. First Implementation Method

[0027] 1-1. System Overview

[0028] Figure 1 This is a schematic diagram showing the system 100 used in the lighting control method according to the first embodiment. Figure 1As shown, the system 100 includes a lighting device 10 and a terminal device 30.

[0029] The lighting device 10 is a device with a lighting function. In this embodiment, in addition to the lighting function, the lighting device 10 also has a projection function of projecting an image G onto a projection surface SC. The projection surface SC is an object such as a screen or a wall. Furthermore, the projection surface SC is not limited to a plane; for example, it can also be a curved surface. In addition, the projection function is used as needed and can also be omitted. Furthermore, the lighting device 10 may have functions different from the projection function to serve functions other than lighting.

[0030] The lighting device 10 includes a housing 20, in which an input device 16 and a lighting unit 17 are disposed. The lighting device 10 causes the plurality of light sources 17a of the lighting unit 17 (described later) to emit light with a light emission pattern and color based on configuration information DP1 or configuration information DP2 (described later), as will be described in detail later. Furthermore, the lighting device 10 switches between configuration information DP1 and configuration information DP2 based on the input result from the input device 16, thereby applying this switching to the light emission of the plurality of light sources 17a (described later).

[0031] The terminal device 30 is a device that can communicate with the lighting device 10 and has the functions of controlling the operation of the lighting device 10 and changing the settings of the lighting device 10. More specifically, the terminal device 30 generates configuration file information DP1 and DP2, which will be described later, and sends the generated configuration file information DP1 and DP2 to the lighting device 10.

[0032] In the illustrated example, terminal device 30 is a smartphone. However, terminal device 30 is not limited to a smartphone; for example, it could be a laptop or desktop computer, or even a tablet.

[0033] 1-2. Lighting fixtures and terminal devices

[0034] Figure 2 This is a block diagram of the lighting device 10 and the terminal device 30 according to the first embodiment. Figure 2 As shown, the lighting device 10 includes a storage device 11, a processing device 12, a communication device 13, an image processing circuit 14, an optical device 15, an input device 16, and a lighting unit 17. These components are connected in a manner that allows them to communicate with each other. The processing device 12 is an example of a "control device." Furthermore, if the lighting device 10 does not have a projection function, the image processing circuit 14 and the optical device 15 may be omitted.

[0035] Storage device 11 is a storage device that stores the program executed by processing device 12 and the data processed by processing device 12. Storage device 11 may be configured to include, for example, a hard disk drive or a semiconductor memory. In addition, part or all of storage device 11 may also be a storage device or server external to lighting device 10.

[0036] The storage device 11 stores the program PR2 and the data structure DS1.

[0037] Program PR2 is a program used together with program PR1 (described later) to execute the lighting control method described later.

[0038] The data structure DS1 contains the first set of configuration file information DP1 and the second set of configuration file information DP2.

[0039] Configuration information DP1 and DP2 represent the time-varying emission patterns and colors of multiple light sources 17a, respectively, and include the first information D1 and the second information D2 described later. However, compared with the first configuration information DP1, at least a portion of the first information D1 and the second information D2 differ in the second set of configuration information DP2. Therefore, the emission patterns and color variations represented by configuration information DP1 and DP2 are different from each other. Details regarding data structure DS1 will be discussed later based on... Figures 5 to 8 The luminescence pattern is a time-varying pattern of the individual illumination and extinguishing of multiple light sources 17a. The luminescence pattern can also be referred to as a pattern of the illumination and flickering of multiple light sources 17a. The luminescence pattern corresponds to the time-series change of the grayscale values ​​of the multiple light sources 17a determined based on the configuration information DP1 and DP2 described later. Alternatively, the luminescence pattern may also include the time-series change of the grayscale values ​​of the multiple light sources 17a based on the effect information DE1 and DE2 of the second embodiment described later.

[0040] In this embodiment, the configuration file information DP1 and DP2 each include, in addition to the first information D1 and the second information D2, identification information D0, the third information D3, the fourth information D4, the fifth information D5, the sixth information D6, and the seventh information D7, which will be described in detail later. However, regarding the configuration file information DP1 and configuration file information DP2, at least a portion of the data contained in either the first information D1 or the second information D2 is different. Furthermore, in this embodiment, the method of using two configuration file information DP1 and DP2 is described, but it is not limited to this method. The number of configuration file information is arbitrary and can be one or more.

[0041] The processing device 12 is a processing device that controls various parts of the lighting device 10 and processes various data. The processing device 12 includes, for example, at least one processor such as a CPU (Central Processing Unit). Furthermore, the processing device 12 can be composed of a single processor or multiple processors. Additionally, some or all of the functions of the processing device 12 can be implemented using hardware such as a DSP (Digital Signal Processor), ASIC (Application Specific Integrated Circuit), PLD (Programmable Logic Device), or FPGA (Field Programmable Gate Array). Furthermore, the processing device 12 can also be integrated with the image processing circuit 14.

[0042] Communication device 13 is a communication device capable of communicating with various devices, communicating with terminal device 30, or acquiring image data from a device not shown. For example, communication device 13 is a wireless communication device such as LPWA (Low Power Wide Area), a wireless LAN including Wi-Fi, or Bluetooth. "Wi-Fi" and "Bluetooth" are registered trademarks. Furthermore, communication device 13 is not limited to wireless communication devices; it can also be a wired communication device such as a LAN (Local Area Network), USB (Universal Serial Bus), or HDMI (High Definition Multimedia Interface). "HDMI" is a registered trademark.

[0043] The image processing circuit 14 is a circuit that performs necessary processing on the image data from the communication device 13 and inputs it to the optical device 15. The image processing circuit 14 may have, for example, a frame memory (not shown), in which the image data is expanded, and various processes such as resolution conversion, resizing, and distortion correction are performed as appropriate before being input to the optical device 15. Furthermore, the image processing circuit 14 may also perform OSD (On Screen Display) processing, as needed, to generate image information for menu display or operation guidance and synthesize it into the image data.

[0044] The optical device 15 is a device for projecting image light onto the projection surface SC. The optical device 15 includes a light source 15a, a light modulator 15b, and a projection optical system 15c.

[0045] The light source 15a is configured to include, for example, a halogen lamp, a xenon lamp, an ultra-high pressure mercury lamp, an LED (Light Emitting Diode), or a laser light source, emitting red, green, and blue light respectively. The light modulator 15b depicts an image based on image data supplied from the terminal device 30. The light modulator 15b includes three light modulation elements corresponding to red, green, and blue. Each light modulation element includes, for example, a transmissive liquid crystal panel, a reflective liquid crystal panel, or a DMD (Digital Micromirror Device), which generates image light of each color by modulating light of the corresponding color. The image light of each color generated by the light modulator 15b is combined by a color synthesis optical system to become full-color image light. The projection optical system 15c is an optical system including a projection lens that images and projects the full-color image light from the light modulator 15b onto the projection surface SC. The image depicted in the light modulator 15b, i.e., the depicted image, is projected onto the projection surface SC via the projection lens.

[0046] Input device 16 is a device that receives operations from the user. In this embodiment, input device 16 is a touch sensor. However, input device 16 is not limited to a touch sensor; for example, it may be a proximity sensor, a push-button switch, or a slider.

[0047] The lighting unit 17 has multiple light sources 17a. Each light source 17a is, for example, a light-emitting element such as a full-color LED element capable of changing the emitted color and brightness, and capable of changing the brightness ratio of red, green, and blue emission. The configuration of the multiple light sources 17a will be discussed later based on... Figure 3 and Figure 4 This will be explained. In addition, the lighting unit 17 may include not only the light-emitting element, but also a driving circuit for driving the light-emitting element.

[0048] In the lighting device 10 described above, the processing device 12 functions as a projection control unit 12a and a lighting control unit 12b by executing the program PR2 stored in the storage device 11. Therefore, the processing device 12 includes a projection control unit 12a and a lighting control unit 12b.

[0049] The projection control unit 12a controls the operation of the image processing circuit 14 and the optical device 15. More specifically, the projection control unit 12a projects the image G onto the projection surface SC by controlling the operation of the image processing circuit 14 and the optical device 15.

[0050] The lighting control unit 12b controls the driving of the lighting unit 17. More specifically, the lighting control unit 12b obtains the configuration information DP1 and DP2 contained in the data structure DS1 from the terminal device 30 via the communication device 13, and stores the obtained configuration information DP1 and DP2 in the storage device 11. In addition, based on the input results from the input device 16, the lighting control unit 12b controls the illumination state of the lighting unit 17, such as brightness, illumination pattern, or illumination color, to the illumination state based on the configuration information DP1 or configuration information DP2.

[0051] Thus, based on the first information D1 and the second information D2 (described later) contained in the configuration file information DP1 or configuration file information DP2, the processing device 12 causes each of the multiple light sources 17a to emit light, thereby enabling the control of the light source 17a with high versatility corresponding to various lighting methods.

[0052] On the other hand, such as Figure 2 As shown, the terminal device 30 includes a storage device 31, a processing device 32, a communication device 33, a display device 34, and an input device 35. They are connected in a manner that enables them to communicate with each other.

[0053] Storage device 31 is a storage device that stores programs such as the operating system and applications executed by processing device 32, as well as data processed by processing device 32. Storage device 31 may include, for example, a hard disk drive or a semiconductor memory. In addition, part or all of storage device 31 may be an external storage device of terminal device 30, or it may be installed on an external device such as a server connected to terminal device 30 via a communication network such as the Internet.

[0054] The storage device 31 stores the program PR1 and the data structure DS1.

[0055] Program PR1 is a program used together with Program PR2 described above to execute the lighting control method described later.

[0056] The processing device 32 is a processing device that has the functions of controlling various parts of the terminal device 30 and processing various types of data. The processing device 32 is configured to include, for example, a processor such as a CPU. Furthermore, the processing device 32 can be composed of a single processor or multiple processors. Additionally, some or all of the functions of the processing device 32 can be implemented using hardware such as a DSP, ASIC, PLD, or FPGA.

[0057] Communication device 33 is a communication device capable of communicating with the lighting device 10, etc. Communication device 33 can be, for example, an LPWA, a wireless LAN including Wi-Fi, Bluetooth, or other wireless communication devices. "Wi-Fi" and "Bluetooth" are registered trademarks. Furthermore, communication device 33 can also be a wired communication device such as a wired LAN, USB, or HDMI. "HDMI" is a registered trademark. Additionally, communication device 33 can also communicate with devices other than the lighting device 10.

[0058] The display device 34 displays various images under the control of the processing device 32. The display device 34 is, for example, a display device that includes various display panels such as liquid crystal display panels and organic EL display panels.

[0059] Input device 35 is an input device that accepts operations from the user. For example, input device 35 may be configured to include a touchpad, touch panel, or mouse as a pointing device. In the case where input device 35 includes a touch panel, it may also serve as a display device 34.

[0060] In the terminal device 30 described above, the processing device 32 executes the program PR1 stored in the storage device 31 to implement various functions required for the lighting control method described later. More specifically, the processing device 32 causes the display device 34 to display an image for controlling and setting the lighting unit 17, or generates a data structure DS1 based on the input result of the input device 35 using the image, or causes the communication device 33 to send the data structure DS1 to the lighting device 10.

[0061] 1-3. Multiple light sources

[0062] Figure 3 This is an explanatory diagram of an example of the housing 20 of the lighting device 10. Figure 3 In the example shown, the housing 20 is a cube shape with a bottom surface 21, a top surface 22, and four side surfaces 23. An input device 16 serving as a touch sensor and an illumination unit 17 are provided on the top surface 22. In addition, one of the four side surfaces 23 has an opening 23a for allowing projection from the optical device 15.

[0063] The lighting section 17 is arranged in a ring shape, surrounding the input device 16 along the outer periphery of the top surface 22. Furthermore, the shape of the housing 20 is not limited to the illustrated example and is arbitrary. Additionally, the arrangement, shape, and number of the lighting sections 17 are not limited to the illustrated example and are arbitrary.

[0064] Figure 4 It is set in Figure 3 An explanatory diagram of the multiple light sources 17a of the housing 20 shown. (See diagram for reference.) Figure 4As shown, the illumination unit 17 includes a plurality of light sources 17a arranged in a ring. In the illustrated example, the illumination unit 17A includes 36 light sources 17a. Furthermore, the number of light sources 17a included in the illumination unit 17A is not limited to the illustrated example and is arbitrary.

[0065] Each light source 17a includes light-emitting elements 17a1, 17a2, and 17a3. Light-emitting element 17a1 is an example of a "first light-emitting element," emitting light of a first wavelength. Light-emitting element 17a2 is an example of a "second light-emitting element," emitting light of a second wavelength different from the first wavelength. Light-emitting element 17a3 is an example of a "third light-emitting element," emitting light of a third wavelength different from both the first and second wavelengths. For example, light-emitting element 17a1 emits red light, light-emitting element 17a2 emits green light, and light-emitting element 17a3 emits blue light. By balancing the luminous intensities of these light-emitting elements 17a1, 17a2, and 17a3, each light source 17a can emit light in full color.

[0066] Furthermore, the number of light-emitting elements in each light source 17a may be two or less or four or more. In addition, the multiple light-emitting elements in each light source 17a may include multiple light-emitting elements that emit light of the same wavelength as each other.

[0067] The multiple light sources 17a included in the lighting unit 17 described above can be individually controlled in terms of emission color and brightness. As a result, the emission pattern and emission color of the multiple light sources 17a included in the lighting unit 17 can be varied in a variety of ways.

[0068] Previously, performances based on the time-varying patterns and colors of multiple light sources 17a were programmed. Therefore, changes or customizations to the performance required program modifications. These modifications necessitated an understanding of the program's internal structure, leading to high costs. Furthermore, program modifications required firmware updates.

[0069] Therefore, in the lighting device 10, the content of the performance is defined as a data structure DS1, which is a predetermined structure. Thus, the performance can be changed or customized by modifying the defined data. That is, the lighting device 10 causes the multiple light sources 17a included in the lighting unit 17 to emit light with a light emission pattern and color based on the configuration file information DP1 or configuration file information DP2. The method using data structure DS1 allows for diverse performances to be achieved by changing the data even without changing the program each time, thus offering greater versatility compared to methods that perform performances through programming.

[0070] 1-4. Configuration file information

[0071] Figure 5This is a diagram illustrating the configuration file information DP1. Configuration file information DP1 is, for example, as follows: Figure 5 As shown, it is defined as binary data. Therefore, it is defined as a fixed structure with a fixed configuration address and size. Hereinafter, the configuration information DP1 is shown when each light source 17a has three light-emitting elements 17a1, 17a2, and 17a3 that emit red light, green light, and blue light.

[0072] Furthermore, the data structures of configuration file information DP1 and configuration file information DP2 are identical. Therefore, configuration file information DP1 will be described representatively below, while a detailed description of configuration file information DP2 will be omitted. Additionally, the data structure of configuration file information DP1 is not limited to the example shown below; for example, the order or number of items can be appropriately changed, and items not shown can be added. Furthermore, free space can be utilized when adding items. Additionally, configuration file information DP1 can be divided into multiple units. Furthermore, the illustrated values ​​or memory addresses are merely examples and can be arbitrarily changed.

[0073] Specifically, the configuration information DP1 of data structure DS1 includes identification information D0, first information D1, second information D2-1 to D2-n, third information D3, fourth information D4, fifth information D5, sixth information D6, and seventh information. n is an integer greater than or equal to 1. Hereinafter, each second information D2-1 to D2-n is sometimes referred to as second information D2 without distinction. Additionally, second information D2-1 to D2-n is sometimes referred to as n groups of second information D2. Furthermore, second information D2-k is sometimes referred to as the kth group of second information D2. k is an integer greater than or equal to 1 and less than or equal to n.

[0074] Here, as Figure 5 As shown, the configuration file information DP1 is divided into a header area, a palette area, and a data area. The header area contains header information DH. Header information DH contains identification information D0, third information D3, fourth information D4, fifth information D5, sixth information D6, and seventh information. The palette area contains first information D1. The data area contains second information D2-1 to D2-n.

[0075] Identification information D0 is used to identify configuration file information DP1 from other configuration file information. In the illustrated example, identification information D0 includes information representing the identifier, type, version, name, and mode ID. The identifier, type, and version are fixed values ​​in this embodiment, but can be changed. Alternatively, fixed values ​​can be omitted. Furthermore, if there is only one set of configuration file information, identification information D0 can be omitted.

[0076] Information D1 is color information containing information representing multiple distinct colors. In the illustrated example, information D1 contains information about an RGB palette that can represent 256 shades of gray in red (R), green (G), and blue (B). Information D1 in profile information DP1 is an example of "Group 1 Information D1," and information D2 in profile information DP2 is an example of "Group 2 Information D2."

[0077] Each piece of second information D2 represents the display information of the light emission pattern and color of the multiple light sources 17a of the lighting device 10. n sets of second information D2 associate any color from the multiple colors shown in the first information D1 with the multiple light sources 17a of the lighting device 10. In the illustrated example, n=290, and the n sets of second information D2 are 290 datasets (Data Set0-Data Set289).

[0078] Information D3 is the number of colors contained in information D1, representing the number of palettes. Therefore, the number of colors contained in information D1 can be easily determined based on information D3.

[0079] Information D4, the fourth piece of information, represents the value of n, indicating the number of data sets. Therefore, the value of n can be easily determined based on information D4. That is, the quantity of information D2, the second piece of information, can be easily determined based on information D4.

[0080] Information D5 indicates whether the process of repeatedly reading out information D2 from group 1 to group n is repeated, indicating whether the loop is enabled. Therefore, information D5 can be used to determine whether the process of repeatedly reading out information D2 from group n is performed. Furthermore, if the loop is enabled, the performance using information D2 from group n can be repeated.

[0081] Information D6 represents the number of groups of information D2 applied per unit time in n groups of information D2, and for example, it represents fps (frames per second). Therefore, the number of groups of information D2 applied per unit time can be determined based on information D6. Here, the number of groups of information D2 applied per unit time is the baseline of the number of frames updated per second, i.e., fps. For example, in the case of 5 fps, multiple light sources 17a emit light in a pattern of 5 frames per second. Furthermore, the unit time is not limited to 1 second and is arbitrary. For example, it could be 5 seconds, 10 seconds, or 1 minute.

[0082] Information D7 is information indicating the number of LEDs among the multiple light sources 17a. Therefore, the number of LEDs among the multiple light sources 17a can be determined based on information D7.

[0083] Figure 6 This is an explanatory diagram illustrating the structure of configuration file information DP1. In Figure 6 In the diagram, the upper section shows a structural example of the header area, the middle section shows a structural example of the palette area, and the lower section shows a structural example of the data area. Figure 7 This is an explanatory diagram of the header and palette areas of the configuration file information DP1. Figure 8 This is an explanatory diagram of the data area of ​​configuration file information DP1.

[0084] like Figure 6 upper middle section and Figure 7 As shown, identification information D0 is stored in addresses 0000 to 0019. Here, identification information D0 includes information D0a representing the identifier, information D0b representing the type and version, information D0c representing the name, and information D0d representing the pattern ID. This information is stored in the order of D0a, D0b, D0c, and D0d. In the illustrated example, information D0a is stored in addresses 0000 to 0003. Information D0b is stored in address 0004. Information D0c is stored in addresses 0005 to 0018. Information D0d is stored in address 0019.

[0085] Information D3, D4, D5, D6, and D7 are saved in the order of D6, D7, D3, D4, and D5. In the illustrated example, information D6 is saved to address 001A. Information D7 is saved to address 001B. Information D3 is saved to address 001C. Information D4 is saved to addresses 001D to 001E. Information D5 is saved to address 001F. Furthermore, addresses 0020 to 003A are the free area Dx.

[0086] like Figure 6 As shown in the middle section, the first information D1 is stored in addresses 003B to 0337. Here, the first information D1 represents one color through three consecutive addresses. Specifically, the three consecutive addresses represent the grayscale values ​​of R, G, and B in sequence. Therefore, the first information D1 contains information corresponding to the light-emitting elements 17a1, 17a2, and 17a3 of any light source 17a (Palette(x)R, Palette(x)G, Palette(x)B). Here, x in Palette(x) is the palette number, which is an integer from 0 to 255 in the illustrated example. Furthermore, in Figure 7 The image shows four sets of information D1a, D1b, D1c, and D1d, which are representative of the 256 sets of information that constitute the first information D1. The grayscale value can also be 0. When the grayscale values ​​of R, G, and B are all 0, the light source 17a can also be in an off state.

[0087] Here, in Figure 6 In the middle section, “palette0 R” to “palette255 R” indicate the brightness of light-emitting element 17a1, “palette0 G” to “palette255 G” indicate the brightness of light-emitting element 17a2, and “palette0 B” to “palette255 B” indicate the brightness of light-emitting element 17a3.

[0088] Thus, the first information D1, for each of the plurality of light sources 17a, includes information indicating the brightness of light-emitting element 17a1, information indicating the brightness of light-emitting element 17a2, and information indicating the brightness of light-emitting element 17a3. The combination of this information represents any color among the plurality of colors shown in the first information D1. This allows the emitted color of each light source 17a to be changed. Here, the information indicating the brightness of light-emitting element 17a1 is an example of "first brightness information." The information indicating the brightness of light-emitting element 17a2 is an example of "second brightness information."

[0089] like Figure 6 As shown in the lower middle section, the nth group of second information D2 is saved to addresses 0338 to 2BFF. Here, the nth group of second information D2, namely second information D2-1 to D2-n, is saved in the order in which it is applied to multiple light sources 17a in a time sequence. Specifically, in Figure 8 Each group of second information D2-1 contains 36 data points. The processing device 12 reads the number of light sources 17a (36) shown in the seventh information D7, and applies it sequentially to each of the 36 light sources 17a, starting from the beginning. By sequentially executing this process from group 1, n groups of second information D2 are sequentially applied to multiple light sources 17a. Furthermore, the duration of applying one group of second information D2 is determined based on the sixth information. Additionally, each group of second information D2 consists of multiple pieces of information corresponding to the multiple light sources 17a, each piece of information representing the correspondence between the color shown in the first information D1 and each light source 17a. Furthermore, in... Figure 8 In the example, the second information D2-1 to D2-6 in the second information D2-1 to D2-n are shown representatively. For example, the first 9 data from the beginning of the second information D2-1 in the first group are "00", so the processing device 12 makes the first to the ninth light source 17a of the plurality of light sources 17a emit light in the color shown in Palette (0) by referring to Palette (0) which is the first data of the first information D1. Similarly, the processing device makes the tenth to the eighteenth light source 17a emit light in the color shown in Palette (1), makes the nineteenth to the twenty-seventh light source 17a emit light in the color shown in Palette (2), and makes the twenty-eighth to the thirty-sixth light source 17a emit light in the color shown in Palette (3).

[0090] Thus, in this embodiment, when n is 2 or more, and an integer of 1 or more and less than n-1 is set to m, the (m+1)th group of second information D2 in the nth group of second information D2 is saved to the data area where the mth group of second information D2 is read next. Therefore, the nth group of second information D2 can be read in the order of the first group of second information D2 to the nth group of second information D2. As a result, the light emission control of the light source 17a using the nth group of second information D2 can be performed smoothly in the order of the first group of second information D2 to the nth group of second information D2.

[0091] Here, the m-th group of second information D2 is used for the emission of multiple light sources 17a during the m-th period, and the (m+1)-th group of second information D2 is used for the emission of multiple light sources 17a during the (m+1)-th period, which is different from the m-th period. In this embodiment, the (m+1)-th period is the period following the m-th period. For example, the first group of second information D2 is used for the emission of multiple light sources 17a during the first period, and the second group is used for the emission of multiple light sources 17a during the second period following the first period. Furthermore, the lengths of the m-th period and the (m+1)-th period may be different from each other, but are preferably equal. Thus, each period can be made to correspond to the control cycle, and as a result, the emission control of multiple light sources 17a can be performed appropriately.

[0092] Furthermore, the number of multiple light sources 17a corresponds to the division position of the second information D2. That is, the seventh information D7 can also be said to represent the division position of the second information D2. The division position of the second information D2 is the division position between the second information D2 of the m-th group and the second information D2 of the (m+1)-th group.

[0093] As described above, the nth set of second information D2 is information that associates any color among the multiple colors shown in the first information D1 with each of the multiple light sources 17a. Thus, the data structure DS contains the first information D1 and the second information D2, thereby enabling the control of the light source 17a with high versatility to correspond to various lighting methods.

[0094] 1-5. Lighting Control Methods

[0095] Figure 9 This is a flowchart illustrating the process of the lighting control method according to the first embodiment. Figure 9 The lighting control method shown includes steps S1 to S7. These steps are executed by the processing device 12. That is, the processing device 12 executes steps S1 to S7.

[0096] Specifically, firstly, in step S1, the processing device 12 obtains the configuration file information DP1 and DP2. More specifically, in step S1, the processing device 12, which functions as the lighting control unit 12b, receives the configuration file information DP1 and DP2 from the terminal device 30 via the communication device 13, thereby obtaining the configuration file information DP1 and DP2.

[0097] Following step S1, in step S2, the processing device 12 stores the configuration file information DP1 and DP2. More specifically, in step S2, the processing device 12, which functions as the lighting control unit 12b, stores the received configuration file information DP1 and DP2 in the storage device 11.

[0098] Following step S2, in step S3, the processing device 12 determines whether the input device 16 has accepted the operation. More specifically, in step S3, the processing device 12, which functions as the lighting control unit 12b, determines whether a prescribed operation has been performed on the input device 16. This prescribed operation is related to the emission of light from the multiple light sources 17a.

[0099] When the input device 16 receives an operation (step S3: Yes), in step S5, the processing device 12, which functions as the lighting control unit 12b, switches the emission profile information applied to the multiple light sources 17a from one of profile information DP1 and profile information DP2 to the other. Then, in step S6, the multiple light sources 17a emit light with an emission pattern and emission color based on profile information DP1 or profile information DP2. For example, if the initial operation is received in step S5 (step S5: Yes), profile information DP1 is applied. From the second time onwards, whenever an operation is received, switching control is performed to switch from the currently applied profile information DP1 or profile information DP2 to the other profile information DP1 or profile information DP2. Here, according to the data structure described above, the applied profile information DP1 or profile information DP2 is read into the processing device 12.

[0100] After step S6, or if the input device 16 does not accept the operation (step S3: No), in step S7, the processing device 12 determines whether to end. This determination is made, for example, based on the user's operation on the terminal device 30 or the input device 16.

[0101] If the process does not terminate (step S7: No), the processing device 12, which functions as the lighting control unit 12b, proceeds to step S3 as described above. Thus, the steps corresponding to the operation of the input device 16 in steps S3 to S6 are repeatedly executed.

[0102] In the case of completion (step S7: yes), the processing device 12, which functions as the lighting control unit 12b, ends the processing.

[0103] 1-6. Light emission from multiple light sources

[0104] Figure 10 This is an explanatory diagram of the acceptance of the operation in step S3 and the emission of light from multiple light sources 17a in step S6. Figure 10 In the center, the lighting device 10 is shown before the operation of the input device 16 is performed. Figure 10 On the upper side, an illumination device 10 is shown that, after receiving an operation on the input device 16, the illumination unit 17 emits light in a light-emitting pattern and color based on the configuration file information DP1. Figure 10On the lower side, an illumination device 10 is shown that, after receiving an operation on the input device 16, the illumination unit 17 emits light in a light emission pattern and color based on the configuration file information DP2. Furthermore, in Figure 10 In the middle, the luminous part 17, which is in a luminous state, is shown in shadow.

[0105] like Figure 10 As shown, if the input device 16 is subjected to a predetermined operation (step S3: Yes), the illumination unit 17 alternately switches between emitting light according to the light emission pattern and color based on the configuration file information DP1 and emitting light according to the light emission pattern and color based on the configuration file information DP2 (steps S5, S6). Figure 10 In the example shown, the specified operation is a long press touch operation of hand H.

[0106] Here, in Figure 10 In the example shown above, the brightness or color of the illumination unit 17 changes by moving along the circumferential direction RDa of the illumination device 10. Additionally, in Figure 10 In the example shown on the lower side, the brightness or color of the illumination unit 17 changes by moving along the direction RDc toward the front of the illumination device 10. Furthermore, the way the illumination pattern and color of the illumination unit 17 change is not limited to the example shown and is arbitrary.

[0107] Furthermore, the operation specified in step S3 is not limited to the example shown in the figure. For example, if the input device 16 is a touch sensor that detects contact, it can be any one of the following operations: long press, short press, single click, double click, zoom operation, circle drawing operation, scrolling in the first direction, and scrolling in the second direction different from the first direction.

[0108] In the above lighting control method, each of the multiple light sources 17a emits light based on the first information D1 and the nth set of second information D2, thus enabling the control of the light sources 17a with high versatility to correspond to various lighting methods.

[0109] 2. Second Implementation Method

[0110] Hereinafter, the second embodiment of this disclosure will be described. Furthermore, the following description will focus on the differences from the first embodiment, and the description of matters that are the same as those in the first embodiment will be omitted.

[0111] Figure 11 This is a block diagram of the lighting device 10A and the terminal device 30A according to the second embodiment. Figure 11 The system 100A shown includes a lighting device 10A and a terminal device 30A instead of the lighting device 10 and terminal device 30 of the first embodiment.

[0112] The lighting device 10A is configured the same as the lighting device 10 of the first embodiment, except that it uses program PR4 and data structure DS2 instead of program PR2 and data structure DS1 of the first embodiment.

[0113] The data structure DS2 is identical to the data structure DS1 in the first embodiment, except that it includes effect information DE1 and DE2. Effect information DE1 and DE2 are respectively information used to adjust the brightness of the multiple light sources 17a. Specifically, effect information DE1 and DE2 represent different brightness adjustments.

[0114] In the lighting device 10A, the processing device 12 functions as the projection control unit 12a and the lighting control unit 12c by executing the program PR4 stored in the storage device 11.

[0115] The lighting control unit 12c obtains the data structure DS2 from the terminal device 30 via the communication device 13 and stores the obtained data structure DS2 in the storage device 11. In addition, based on the input results from the input device 16, the lighting control unit 12c controls the lighting state of the lighting unit 17, such as the brightness, light emission pattern, or light emission color, to a lighting state based on a combination of configuration file information DP1 or configuration file information DP2 and effect information DE1 or effect information DE2.

[0116] The terminal device 30A is configured similarly to the terminal device 30 of the first embodiment, except that it uses program PR3 and data structure DS2 instead of program PR1 and data structure DS1 of the first embodiment.

[0117] In the terminal device 30A, the processing device 32 executes the program PR3 stored in the storage device 31 to implement various functions required for the lighting control method described later. More specifically, the processing device 32 causes the display device 34 to display an image for controlling and setting the lighting unit 17, or generates a data structure DS2 based on the input result of the input device 35 using the image, or causes the communication device 33 to send the data structure DS2 to the lighting device 10.

[0118] Figure 12 This is an explanatory diagram of an example of effect information DE1. For example... Figure 12As shown, effect information DE1 includes a header area and a data area. The header area contains p groups of information D8-1 to D8-p (8th information) and D9 (9th information). p is an integer greater than or equal to 1. Hereinafter, information D8-1 to D8-p (8th information) are sometimes referred to as information D8 (8th information). In the example shown, p is 85. Sometimes information D8-j (8th information) is referred to as information D8 (8th information) of group j. j is an integer greater than or equal to 1 and less than p. Additionally, the header area contains type information (typeID). Type information is the identification information that distinguishes effect information DE1 from effect information DE2. Other items included in the header area of ​​effect information DE1 are the same as those included in configuration file information DP1, therefore detailed explanations are omitted.

[0119] The 8th information D8 in group p represents the brightness applied to two or more light sources 17a out of multiple light sources 17a, and indicates the gain in the driving of the light sources 17a. Therefore, the brightness of two or more light sources 17a out of multiple light sources 17a can be adjusted based on the 8th information D8. Furthermore, the 8th information D8 can be represented as data through grayscale values, control values ​​in the driving process, or coefficients used when calculating the control values ​​in the driving process.

[0120] When p is 2 or more, as in this embodiment, the p-group eighth information D8 represents different brightness levels. Thus, in this embodiment, when p is 2 or more, the p-group eighth information D8 includes the first group eighth information D8-1 and at least a portion of the second group eighth information D8-2, which differs from the first group eighth information D8. Therefore, the brightness of two or more of the plurality of light sources 17a can be adjusted to the brightness shown in the first group eighth information D8, or adjusted to the brightness shown in the second group eighth information D8.

[0121] Information D9 represents the time from the start of execution of group 1 of information D8 in group p to the end of execution of group p. Therefore, the execution time of information D8 in group p can be adjusted based on information D9.

[0122] Figure 13 This is an illustrative diagram based on the gain of information D8 and information D9. In Figure 13 In the diagram, the horizontal axis represents time, and the vertical axis represents the grayscale value shown in information D8 (the 8th piece of information). For example... Figure 13As shown, by controlling the brightness of light source 17a with the grayscale shown in group p of information 8 within time T as indicated by information 9 D9, the brightness of light source 17a can be adjusted in a manner that changes according to a time sequence. In this embodiment, information 8 D8 contains data showing an increase in gain from information 8-1 of group 1 to information 8-p of group p. Therefore, when applied in ascending order from information 8-1 of group 1 to information 8-p of group p, such as... Figure 13 This results in a curve showing the increase in brightness over time. However, when applied in descending order starting from information D8-p, the brightness decreases over time. Therefore, the brightness of light source 17a can be adjusted by fading in or out. That is, a flickering effect of light source 17a can be performed. Furthermore, whether to fade in or out is determined simply by specifying the reading order of information D8. Alternatively, by reading information D8 in ascending order followed by descending order, repeated fade-in and fade-out effects can be performed. In this way, the brightness of multiple light sources 17a can be varied according to the content and reading order of the data in information D8.

[0123] Figure 14 This is an explanatory diagram of the driving mechanism for light source 17a. (As shown...) Figure 14 As shown, each light source 17a is driven by a drive signal SS output from the drive circuit 17c provided in the illumination unit 17. The drive signal SS is a current signal. The drive circuit 17c is a circuit that generates the drive signal SS based on the control signal DD from the arithmetic circuit 17b, and generates the drive signal SS by adjusting the current from a power source (not shown) based on the control signal DD. The control signal DD is a digital signal. The arithmetic circuit 17b is a circuit that generates the control signal DD based on the 8th information D8 and the 2nd information D2. More specifically, the arithmetic circuit 17b generates the control signal DD by multiplying the control value for emitting light in the color shown in the 2nd information D2 with the control value for emitting light in the brightness shown in the p-group 8th information D8. Therefore, the control signal DD represents the product of these control values. In addition, the drive signal SS is a signal based on the product of these control values.

[0124] Figure 15 This is a flowchart illustrating the process of the lighting control method according to the second embodiment. The lighting control method of this embodiment is the same as the lighting control method of the first embodiment, except that it includes step S6A instead of step S6 in the first embodiment and adds steps S8 and S9.

[0125] In this embodiment, after step S2, in step S8, the processing device 12 acquires effect information DE1 and DE2. More specifically, in step S8, the processing device 12, which functions as the lighting control unit 12c, receives effect information DE1 and DE2 from the terminal device 30 via the communication device 13, thereby acquiring effect information DE1 and DE2. Furthermore, step S8 can be performed simultaneously with step S1, or it can be performed before step S1.

[0126] Following step S8, in step S9, the processing device 12 stores the effect information DE1 and DE2. More specifically, in step S9, the processing device 12, which functions as the lighting control unit 12c, stores the received effect information DE1 and DE2 in the storage device 11. Furthermore, step S9 can be performed simultaneously with step S2 if it is performed after step S8, or it can be performed before steps S1 and S2.

[0127] After step S9, the processing device 12 proceeds to step S3.

[0128] When the input device 16 accepts the operation (step S3: Yes), after step S5, in step S6A, the processing device 12, which functions as the lighting control unit 12c, causes the multiple light sources 17a to emit light in a light emission pattern and light emission color based on a combination of configuration file information DP1 or configuration file information DP2 and effect information DE1 or effect information DE2.

[0129] Here, in step S6A, making each of the plurality of light sources 17a emit light includes making each of the plurality of light sources 17a emit light in a color determined according to the combination of the eighth information D8 and the second information D2 of group p. Thus, it is possible to make each of the plurality of light sources 17a emit light in a color determined according to the combination of the eighth information D8 and the second information D2.

[0130] Furthermore, in step S6A, causing each of the plurality of light sources 17a to emit light includes driving each of the plurality of light sources 17a using a driving signal SS. As described above, the driving signal SS is a signal based on the product of a control value for color emission represented by the second information D2 and a control value for brightness emission represented by the p-group eighth information D8. Therefore, each of the plurality of light sources 17a can emit light in a color determined according to the combination of the eighth information D8 and the second information D2.

[0131] Furthermore, in step S6A, emitting light from each of the multiple light sources 17a includes one or both of the following methods: sequentially emitting light from each of the multiple light sources 17a using p groups of 8th information D8 starting from the first group of 8th information D8; and sequentially emitting light from each of the multiple light sources 17a using p groups of 8th information D8 starting from the p group of 8th information D8. This allows the brightness of the light sources 17a to be adjusted in a way that changes in brightness according to a time sequence. For example, the brightness of the multiple light sources 17a can be faded in or out, or the emission pattern of the multiple light sources 17a can be repeated.

[0132] 3. Variations

[0133] The methods illustrated above can be modified in various ways. The following examples illustrate specific modifications that can be applied to the methods described above. Any two or more methods selected from the following examples can be appropriately combined without contradiction.

[0134] 3-1. Variation Example 1

[0135] The configuration file information DP1 may also contain multiple first information D1s representing different colors or numbers of colors. In this case, any one of the multiple first information D1s is an example of "first information in group 1", and any other first information D1 is an example of "first information in group 2". Thus, when the configuration file information DP1 contains multiple first information D1s representing different colors or numbers of colors, the emission patterns and emission colors of multiple light sources 17a can be switched by selecting any one of the multiple first information D1s. In this case, even without switching between configuration file information DP1 and configuration file information DP2, using the same n groups of second information D2 can achieve emission patterns with different emission colors.

[0136] 3-2. Variation Example 2

[0137] In the above embodiments, the lighting device 10 is exemplified to have a projection function in addition to the lighting function, but it is not limited to this method. The data structure of this disclosure can be applied to various devices with multiple light sources that can change the color of light emission, such as lighting lamps, LED (light-emitting diode) strips, etc.

[0138] Furthermore, the aforementioned data structures DS1 and DS2 can be reused even if the light source device to emit light is changed. In this case, for example, even if the driving circuit of the light source needs to be changed, the circuit that generates the control signals for the light source based on data structures DS1 and DS2 can still be used.

[0139] Furthermore, even if the number of light sources to emit light is changed, only the contents of the corresponding data structures DS1 and DS2 need to be changed, which is much more convenient than controlling the light emission of light sources through programming.

[0140] 3-3. Variation Example 3

[0141] In the above embodiment, the terminal device 30 is shown to set and control one lighting device 10, but it is not limited to this method. The terminal device 30 may also set and control multiple lighting devices 10.

[0142] 3-4. Variation Example 4

[0143] The programs PR1 and PR2 of the above embodiments can also be provided in a state recorded on a computer-readable and non-transitory recording medium. Alternatively, the programs PR1 and PR2 of the above embodiments can also be provided by downloading them from a server to a computer via a network.

[0144] 4. Notes

[0145] The following is a summary published in this note.

[0146] Postscript 1

[0147] Appendix 1, as a preferred example of the data structure disclosed herein, includes: first information, which contains information representing multiple distinct colors; and n sets of second information, which associate any one of the multiple colors represented by the first information with each of the multiple light sources of the lighting device, where n is an integer greater than or equal to 1. In the above manner, when the data structure is applied to a lighting device, each of the multiple light sources can emit light in a color corresponding to the content of the first and second information, thus enabling highly versatile control of the light source corresponding to various lighting methods.

[0148] Appendix 2

[0149] In Appendix 2, which is a preferred example of Appendix 1, each of the plurality of light sources includes a first light-emitting element that emits light of a first wavelength and a second light-emitting element that emits light of a second wavelength different from the first wavelength. The first information includes, for each of the plurality of light sources, first brightness information representing the brightness of the first light-emitting element and second brightness information representing the brightness of the second light-emitting element. The combination of the first brightness information and the second brightness information represents any color among the plurality of colors. In the above manner, the brightness of the first light-emitting element and the brightness of the second light-emitting element can be represented by the first brightness information and the second brightness information, respectively. Therefore, when the data structure is applied to a lighting device, the combination of these can enable each light source to emit light in multiple colors.

[0150] Appendix 3

[0151] In Appendix 3, which is a preferred example of Appendix 1 or Appendix 2, when n is 2 or more, and an integer of 1 or more and n-1 or less is set as m, the (m+1)th group of second information in the nth group of second information is stored in the data area that is read next to the mth group of second information. In the above manner, the (m+1)th group of second information can be read next to the mth group of second information, so it is possible to perform light emission control of the light source that uses the mth group of second information and the (m+1)th group of second information in sequence.

[0152] Appendix 4

[0153] Appendix 4, which is a preferred example of any of Appendix 1 to Appendix 3, also includes a fourth piece of information indicating the value of n. In the above method, the value of n can be easily determined based on this fourth piece of information. Furthermore, even if the values ​​of n are different, a common data structure can be applied, thus providing high versatility.

[0154] Appendix 5

[0155] In Appendix 5, a preferred example of Appendix 4, a fifth piece of information is also included, indicating whether the process of sequentially reading the second information of the nth group from the first group to the nth group is repeatedly performed. In the above method, it is possible to determine whether the process of reading the second information of the nth group is repeatedly performed based on the fifth piece of information. In addition, even if the presence or absence of this repetition is different, a common data structure can be applied, thus exhibiting high versatility.

[0156] Appendix 6

[0157] In Appendix 6, which is a preferred example of any of Appendix 1 to Appendix 5, a sixth piece of information is further included, which indicates the number of groups of the second information applied per unit time in the n groups of the second information. In the above manner, the number of groups of the second information applied per unit time can be determined based on the sixth piece of information. Furthermore, even if the number of groups is different, a common data structure can be applied, thus providing high versatility.

[0158] Postscript 7

[0159] In Appendix 7, which is a preferred example of any of Appendix 1 to Appendix 6, the first information is a first group of first information, and also includes a second group of first information that differs from the first group of first information in at least one color or number of colors. In the above manner, multiple light sources can be controlled with different emission colors using the first group of first information and the second group of first information, which share a common data structure. Therefore, compared to preparing separate control commands for each emission mode, highly versatile light source control can be achieved.

[0160] Postscript 8

[0161] In Appendix 8, which is a preferred example of any of Appendix 1 to Appendix 7, a seventh piece of information indicating the number of the plurality of light sources is also included. In the above manner, the number of the plurality of light sources can be determined based on the seventh piece of information. Furthermore, even if the number is different, a common data structure can be applied, thus providing high versatility.

[0162] Postscript 9

[0163] In Appendix 9, which is a preferred example of any of Appendix 1 to Appendix 8, there is also a group of 8th information p representing the brightness applied to two or more of the plurality of light sources, where p is an integer of 1 or more. In the above manner, when the data structure is applied to the lighting device, the brightness of two or more of the plurality of light sources can be adjusted based on the 8th information, thus enabling more diverse lighting methods.

[0164] Postscript 10

[0165] In Appendix 10, which is a preferred example of Appendix 9, a 9th information is also included, representing the time from the start of execution of the first group of the 8th information in group p to the end of execution of the pth group. In the above manner, the execution time of the 8th information in group p can be adjusted based on the 9th information, thus enabling more diverse lighting methods.

[0166] Postscript 11

[0167] In Appendix 11, which is a preferred example of Appendix 9 or Appendix 10, p is 2 or more, and the p-group of eighth information includes: a first group of eighth information; and a second group of eighth information, at least a portion of which differs from the first group of eighth information. In the above method, since the brightness of two or more light sources among multiple light sources can be adjusted to the brightness shown in the first group of eighth information, or adjusted to the brightness shown in the second group of eighth information, more diverse lighting methods can be achieved.
