Description

[Technical field]

[0001] The present invention relates to an entertainment device that is installed over a wide area, and an entertainment system that uses the entertainment device. The entertainment device includes, for example, a lighting device that can emit light of multiple colors, as will be described in detail later. [Background technology]

[0002] In recent years, with the increasing performance of LED elements, lighting fixtures capable of emitting multiple colors and equipped with wired or wireless (RF) communication functions have been manufactured, and vivid and rapidly changing illumination events are being held all over the country. In addition, more interactive illumination events have also been held, such as the large-scale, quiet illumination events at Noto's Shiroyone Senmaida, which use multiple timer-controlled lighting fixtures in a wide area outdoors, and participants holding sticks or lanterns with built-in multicolor LED lighting fixtures with communication functions that change color in accordance with zones and music (see Patent Documents 1 to 5 and Non-Patent Documents 1 and 2).

[0004] [Non-Patent Document 1] "Color Kinetics FLEX", [online], Color Kinetics Japan Co., Ltd., [searched November 18, 2022], Internet<URL: https: / / www.colorkinetics.co.jp / products / 948> [Non-Patent Document 2] "CSR Topics Wajima Story with Ishikawa Sanken", [online], Sanken Electric Co., Ltd., [searched November 18, 2022], Internet<URL: https: / / www.sanken-ele.co.jp / corp / csr / topics / wajima.htm> Summary of the Invention [Problem to be solved by the invention]

[0005] However, the lighting devices described in Patent Documents 1 and 2 are lighting devices or lighting systems for controlling general lighting, although the color and brightness can be freely changed, and a large amount of money is required to install thousands or tens of thousands of lighting fixtures over a wide area. Therefore, it is not very user-friendly in terms of cost and power consumption.

[0006] The device described in Patent Document 3 is easy to install because it uses wireless communication and is battery-powered, but each light-emitting device has its own unique identification number, and color and brightness must be specified for each identification number. Therefore, high-speed communication is required to control a large number of light-emitting devices, for example 10,000 light-emitting devices, and the power consumption of each light-emitting device increases, resulting in high costs and low marketability.

[0007] The device described in Patent Document 4 allows for a wide range of communication methods, from wired / wireless and power sources, from AC to solar, but for the same reasons as the device described in Patent Document 3, it is not suitable for large-scale use.

[0008] The device described in Patent Document 5 differs from the above examples in that it introduces the concept of a group, but this is intended to set the color and brightness to the same value during control, and since each luminaire has its own unique number, the overall amount of control information (amount of communication) does not change.

[0009] The lighting fixture described in Non-Patent Document 1 is a wired lighting fixture that has become common in recent years, and since individual lights can be controlled in full color at high speed, it is possible to create large-scale illumination with movement. However, in terms of cost and installation work, it is difficult to use it for anything other than profitable applications such as commercial facilities.

[0010] The lighting fixtures described in Non-Patent Document 2 are inexpensive and can be installed simply by inserting them into the ground or hanging them, making it possible to install many of them over a wide area; however, since they are controlled by an internal timer, complex changes or fast, flowing, coordinated control is not possible.

[0011] The present invention aims to compensate for the shortcomings of the above-mentioned existing general lighting fixtures controlled by wireless communication and conventional lighting fixtures that can only be controlled simply and slowly by a timer, and to provide entertainment such as illumination that is inexpensive, well-balanced, and fast-moving by using a large number of entertainment equipment such as lighting fixtures. [Means for solving the problem]

[0012] The entertainment device according to the present invention, which has been made to solve the above problems, comprises: a) an entertainment transmission unit having either or both of a light-emitting unit capable of emitting a plurality of kinds of light and a sound-producing unit capable of emitting a sound; b) a group number storage unit for storing a group number; c) a wireless communication unit that wirelessly receives control information for controlling the operation of the entertainment transmitter assigned to the group number; d) a control unit that controls either or both of light emission and sound generation of the entertainment transmission unit based on the control information received by the wireless communication unit and the group number stored in the group number storage unit; The present invention is characterized by comprising:

[0013] The entertainment system according to the present invention comprises: a plurality of entertainment devices each including an entertainment transmitter having either or both of a light-emitting unit capable of emitting multiple types of light and a sound-producing unit capable of producing sound; a group number storage unit for storing a group number; a wireless communication unit for wirelessly receiving control information for controlling the operation of the entertainment transmitter assigned to the group number; and a control unit for controlling either or both of the light emission and sound production of the entertainment transmitter based on the control information received by the wireless communication unit and the group number stored in the group number storage unit; an information generating device that generates the control information for each group number assigned to each of the plurality of entertainment appliances; a control information transmitting wireless communication device that wirelessly transmits the control information for each group number generated by the information generating device to all of the plurality of entertainment appliances; The present invention is characterized by comprising:

[0014] The "multiple kinds of light" refers to multiple kinds of light that are different from each other in color and / or intensity. Therefore, the control of light emission performed by the control unit refers to the control of the color and / or intensity of this light. Furthermore, the control of sound generation performed by the control unit refers to the control of the overall waveform, including the frequency of the sound (including the superposition of multiple frequencies) and / or intensity.

[0015] The entertainment equipment according to the present invention is an equipment having either or both of a light-emitting unit and a sound-producing unit. This entertainment equipment is realized by a lighting device having a light-emitting unit, a speaker having a sound-producing unit, a lighting device with a speaker having both a light-emitting unit and a sound-producing unit, etc.

[0016] In the entertainment device and entertainment system according to the present invention, a group number is assigned to each of the plurality (hereinafter referred to as "all") of entertainment devices. That is, all (denoted as N) entertainment devices are divided into a plurality (M, where M < N) of groups, and the same group number is assigned to the entertainment devices belonging to each group. Here, the number of entertainment devices belonging to each group may be different for each group.

[0017] The group number may be stored in advance in a group number storage unit. Alternatively, the group number is generated by an information generation device and then transmitted by a wireless communication device to all of the entertainment devices (to be set to belong to the same group). Each of these one or more entertainment devices that has received this wireless signal (and is arranged at a position where reception is possible) stores the group number in the group number storage unit. In the latter case, the wireless communication device that transmits the group number may be used in common with the wireless communication device for control information transmission, or a different wireless communication device for group number setting may be used. Also, in the latter case, the transmission of the group number is performed for each of two or more groups.

[0018] All of the entertainment devices in which the group number is stored in the group number storage unit are arranged at positions corresponding to their respective group numbers. Then, when control information for each group number is transmitted to all of the entertainment devices by wireless communication using the wireless communication device for control information transmission, in each entertainment device, the wireless communication unit receives the control information, and the control unit controls the entertainment transmission unit so as to execute the operation specified by the control information of the group number stored in the group number storage unit. That is, when the entertainment transmission unit has a light emitting unit, the control unit controls the light emitting unit to light up with the color and / or brightness specified by the control information, and when the entertainment transmission unit Pronunciation sectionIf the entertainment transmission unit has both a light-emitting unit and a sound-producing unit, it controls the sound-producing unit so that the sound is produced with a waveform specified by the control information. If the entertainment transmission unit has both a light-emitting unit and a sound-producing unit, it performs both of the above two controls. As a result, entertainment equipment set with the same group number lights up with the same color and / or brightness and / or produces sound with the same waveform. Then, by transmitting different control information for each group number via wireless communication using a wireless communication device for transmitting control information, different groups light up with different colors and / or brightness and / or produce sound with different waveforms.

[0019] According to the entertainment equipment and entertainment system of the present invention, the total number (N) of lighting fixtures are divided into a plurality (M) of groups, and entertainment equipment belonging to the same group are lit with the same color and brightness and / or sound with the same waveform, while entertainment equipment belonging to different groups are lit with different colors and / or brightness and / or sound with different waveforms, thereby making it possible to construct an entertainment system using a large number of entertainment equipment more inexpensively and easily than in the case of controlling individual entertainment equipment. Also, since the operation of a large number of entertainment equipment is controlled by wireless communication, harmonious, fast-moving illumination and realistic sound can be realized by changing the control information transmitted by wireless communication in various ways along a time series.

[0020] The group number storage unit of the entertainment equipment may store two or more (plural) group numbers. In this case, the two or more group numbers are stored in different pages (also called banks) in the group number storage unit. Each of the multiple pages is assigned a page number (or bank number), and the group number is stored in the page of the page number of the group number storage unit. When the illumination system is in operation, the wireless communication device for transmitting control information first transmits a page number (bank number), and each entertainment equipment that receives the page number refers to the page to which the page number is assigned. Then, the wireless communication device for transmitting control information transmits a group number and control information assigned to the group number. The entertainment equipment whose group number stored in the referenced page matches the received group number lights up with a color and / or brightness according to the control information and / or produces a sound with a waveform.

[0021] By setting a group number for each page in this manner, the light emission pattern and sound emission pattern of the entertainment equipment can be changed by changing the page number transmitted by the wireless communication device for transmitting control information, thereby achieving more diverse illumination and sound.

[0022] When using a wireless communication device for setting group numbers and setting group numbers for each page, it is preferable that the wireless communication unit of the entertainment equipment further receives the page number (along with the group number) wirelessly, and that the wireless communication device for setting group numbers transmits the page number and the group number.

[0023] In the entertainment device according to the present invention, the entertainment sending unit has both the light-emitting unit and the sound-generating unit, and the operation of the entertainment sending unit assigned to the group number is the operation of one of the light-emitting unit and the sound-generating unit; the group number storage unit further stores a second group number; the wireless communication unit further receives, by wireless, second control information for controlling an operation of the other of the light-emitting unit and the sound-producing unit assigned to the second group number; The control unit controls an operation of the one device based on the control information and the group number stored in the group number storage unit, and controls an operation of the other device based on the second control information and the second group number stored in the group number storage unit. The following configuration can be adopted.

[0024] In this case, the entertainment system comprises: the information generating device further generates the second control information for each of the second group numbers, The control information transmitting wireless communication device further transmits the second control information to all of the plurality of entertainment appliances by wireless. The following configuration can be adopted.

[0025] In this way, by using an entertainment device having both a light-emitting unit and a sound-producing unit as an entertainment transmission unit, and assigning the operation of one of the light-emitting unit and the sound-producing unit to a group number and the operation of the other of them to a second group number, the light-emitting unit and the sound-producing unit are controlled in different groups. This allows the light-emitting unit and the sound-producing unit to be controlled independently of each other, making it possible to realize more complex expressions.

[0026] Like the group number, the second group number may be stored in advance in a group number memory unit, or may be generated by an information generating device and then transmitted to the entertainment equipment by a wireless communication device (a wireless communication device for transmitting control information, or a different wireless communication device for setting group numbers) and then stored in the group number memory unit of the entertainment equipment.

[0027] The entertainment equipment according to the present invention preferably further comprises a power supply unit using a primary or secondary battery for supplying power to the entertainment transmitter, which eliminates the need to connect wiring for supplying power to each entertainment equipment, thereby reducing the labor required for installation.

[0028] It is preferable that the power supply unit further includes a solar panel and a secondary battery, which eliminates the need to replace the primary battery or charge the secondary battery separately, thereby reducing the hassle.

[0029] The entertainment equipment according to the present invention further comprises: a remaining capacity measuring unit for measuring a remaining capacity of the primary battery or the secondary battery; an output control unit that performs control to reduce an output of the entertainment transmission unit when the remaining amount measured by the remaining amount measuring unit becomes equal to or less than a predetermined value; It can be provided with:

[0030] With this configuration that includes a remaining battery level measuring unit and an output control unit, the output of the entertainment transmission unit can be reduced when the remaining battery level of the primary battery or secondary battery of the power supply unit falls below a predetermined value, thereby extending the time until the entertainment device stops due to so-called dead batteries. By extending this time, it is possible to secure time for replacing the primary battery or charging the secondary battery, thereby preventing the entertainment device from stopping. Effect of the Invention

[0031] According to the present invention, entertainment can be provided by using a large number of entertainment devices at low cost, and by providing well-balanced, fast-moving illumination and realistic sound. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] An embodiment of the present invention will be described with reference to the drawings. First, first to third embodiments will be described, which are an illumination lamp (hereinafter abbreviated as "lamp") that is an entertainment device having only a light-emitting unit (no sound-producing unit) and an illumination system that is an entertainment system using the lamp. Next, fourth to sixth embodiments will be described, which are a lamp with a speaker that is an entertainment device having a light-emitting unit and a sound-producing unit (speaker) and an illumination system using the lamp with a speaker. Finally, modified examples including an entertainment device having only a sound-producing unit (no light-emitting unit) and an entertainment system using the same will be described.

[0034] (1) First embodiment (1-1) Configuration of the lighting fixture and illumination system of the first embodiment 1 shows one embodiment of a lighting device. This lighting device 10 comprises a power supply unit 11, a light-emitting unit 12, an infrared communication receiving circuit (corresponding to the wireless communication unit) 13, a non-volatile memory (group number storage unit) 14, and a CPU circuit 15. The power supply unit 11 comprises a solar power generation panel 111, a secondary battery 112, and a power supply circuit 113 that controls them. The light-emitting unit 12 comprises a red LED that emits red light. element The infrared communication receiving circuit 13 is provided with three LED elements 121-123 that emit different colors, namely, an infrared LED element 121 that emits green light, a green LED element 122 that emits green light, and a blue LED element 123 that emits blue light, and an LED lighting circuit 124 that controls the LED elements 121-123. The infrared communication receiving circuit 13 receives infrared rays transmitted from an infrared communication device 32, which will be described later. The non-volatile memory 14 is a memory in which the stored contents are maintained even if the power supply is interrupted, and is rewritable. The non-volatile memory 14 stores a group number received by the infrared communication receiving circuit 13, as will be described later.

[0035] The CPU circuit 15 is a control unit that collectively controls the power supply unit 11, the light emitting unit 12, the infrared communication receiving circuit 13, and the non-volatile memory 14. Note that, for example, when using control units that are included in an existing power supply device, a light emitting device, an infrared communication device, and a non-volatile memory, (multiple) control units that individually control each unit may be used instead of one CPU circuit 15 that collectively controls them.

[0036] FIG. 2 shows an illumination system 30 of the first embodiment. This illumination system 30 is composed of a plurality of luminaires 10, a personal computer 31 which is an information generating device that generates group numbers to be assigned to each of the plurality of luminaires 10 and control information to be assigned to the luminaires 10 to which the group numbers are assigned, and an infrared communication device 32 which is wirelessly connected to the personal computer 31 and transmits signals of the group numbers and control information to the luminaires 10 by infrared communication. The infrared communication device 32 has an infrared communication interface 321 and an infrared communication signal transmitting section 322, and functions as the wireless communication device for setting the group numbers and the wireless communication device for transmitting the control information. Although the personal computer 31 and the infrared communication device 32 may be connected by wire, it is preferable to connect them wirelessly as described above, since this makes the installation work easier. Also, two sets of the personal computer 31 and the infrared communication device 32 may be prepared, and one may be used as the wireless communication device for setting the group numbers and the other as the wireless communication device for transmitting the control information. By using the personal computer 31 in combination with the infrared communication device 32, it is possible to collectively program a plurality of luminaires 10 that are to be set to the same group number, as will be described later.

[0037] 3 shows an example of distributing control signals by infrared communication to all of a large number of luminaires installed in a wide area, and includes one personal computer 31 and four infrared communication signal transmitters 3221-3224 each wirelessly connected to the personal computer 31. If all of the luminaires 10 are within line of sight, they can also be controlled by a single high-output infrared transmitter. In this example, the personal computer 31 and the infrared communication signal transmitters 3221-3224 may be connected by wire, but wireless connections are preferred as this makes installation easier.

[0038] (1-2) Operation of the Lighting Fixture and Illumination System of the First Embodiment The operation of the luminaires and illumination system of the first embodiment will be described below. In the first embodiment, after an operation of setting a group number for each luminaire, lighting of each luminaire is controlled to generate illumination with changes.

[0039] (1-2-1) Group number setting operation FIG. 4 shows a schematic diagram of the operation when setting one of group numbers 01 to 04 to all (total number) of a plurality of luminaires 10 (note that in FIG. 4 and FIG. 6 described later, the first digit "0" from the top is omitted). Note that the number of group numbers to be set is not limited to four in this example, and may be two or more. Also, while FIG. 4 shows group numbers 01 to 04 being set to the same number of luminaires 10, they may be set to different numbers of luminaires for each group number.

[0040] First, as shown in Fig. 4(a), of all the luminaires 10, the luminaires 10 to which group number 01 is assigned are placed within an area 33 capable of receiving infrared signals transmitted by an infrared communication device 32. The other luminaires may be placed outside the area 33 as shown in Fig. 4(a), and in addition to or instead of this, they may be covered with a cover that blocks infrared rays.

[0041] Then, as shown in FIG. 5(a), the following group number setting signal is generated by the PC 31, and the group number setting signal is sent from the infrared communication device 32 to the luminaires in the area 33. In this example, the group number setting start signal "00H" is sent twice to the luminaire 10, causing the luminaire 10 to enter group number setting mode, and then the infrared communication device 32 sends a signal "01H" indicating the group number. The first two digits of this signal, "01", are the group number. The group number setting signal consisting of 00H, 00H, and 01H up to this point is sent multiple times. In this way, the luminaire 10 receives the same command multiple times, preventing malfunction. The luminaires in the area 33 receive this signal and write their own group number "01" to the non-volatile memory 14.

[0042] Next, the luminaire 10 with group number 1 written is removed from area 33, and the luminaires 10 for which a group number has not yet been set and for which group number 02 is to be set are placed in area 33 (Fig. 4(b)). Then, as above, the infrared communication device 32 transmits a group number setting signal (Fig. 5(b)) to set group number "02" to the luminaires in area 33, and the luminaires 10 in area 33 that receive this signal write the group number "02" to their non-volatile memory 14.

[0043] The same operation is carried out for group numbers 03 and 04 (FIGS. 4(c) and 4(d)), thereby setting group numbers 01 to 04 for all luminaires 10.

[0044] In the above group number setting operation, a luminaire that has successfully completed the instructed task (writing the group number) may have a green LED for a short time, and a luminaire in which an abnormality has occurred may have a red LED for a long time. These lighting operations may be performed while the luminaire 10 is repeatedly receiving the group number setting signal multiple times, as described above. These lighting operations make it easy to determine whether the group number setting has been completed successfully.

[0045] All of the luminaires 10 whose group numbers have been stored in the non-volatile memory 14 in this way are installed at the site where illumination is to be performed. FIG. 6 shows an example of the luminaires 10 installed at the site. In reality, many more luminaires are used, but for ease of illustration and understanding, an example of 8×8=64 luminaires will be described. Each of the 64 circles in FIG. 6 represents one luminaire 10, and the number written at the center of each circle represents the group number (as mentioned above, the first digit from the top of the group number is omitted). In this example, four luminaires 10 with group number 01 are placed at the center, 12 luminaires 10 with group number 02 are placed on the outside, 20 luminaires 10 with group number 03 are placed on the outside of that, and 28 luminaires 10 with group number 04 are placed on the outermost circumference.

[0046] (1-2-2) Controlling the lighting of each luminaire To use (light) the luminaire, the PC 31 generates the following control signal, and then the infrared communication device 32 transmits the control signal to all luminaires 10 at once. First, the control start code "FFH" is followed by a group number designation code "XnnH" (where "nn" is the group number) that designates the group number. Next, color intensity designation codes indicating the red intensity "RmmH", the green intensity "GmmH", and the blue intensity "BmmH" are transmitted. Here, "mm" is a hexadecimal value expressed in two digits (256 levels), and the larger this value is, the brighter (stronger intensity) the LED elements 121-123 corresponding to each color of the luminaire 10 in the group designated by the group number designation code will be lit. Note that here, the same "mm" is used for red, green, and blue, but in reality, a value is set for each color.

[0047] FIG. 7 shows an example of a control signal. In this example, the control start signal "FFH" is followed by the group number designation signal "X01H" and color intensity designation signals "R40H", "G40H", and "B00H". These control signals mean that the four innermost luminaires 10 with group number 01 are lit so that red is at the 64th level (intensity counted from the weakest in decimal, with the intensity of 0 being "level 0". The same applies below), green is at the 64th level, and blue is at 0. By lighting red and green at a 1:1 intensity ratio in this way, the lighting color becomes yellow. In this embodiment, as described below, even in the luminaires with group numbers 02 to 04, the lighting color becomes yellow because red and green are lit at a 1:1 intensity ratio (the intensity value differs for each group).

[0048] Next, a control start signal "FFH" is sent followed by a group number designation signal "X02H" and color intensity designation signals "R80H", "G80H", and "B00H". These control signals mean that the 12 luminaires 10 assigned group number 02 are turned on so that red is at the 128th level, green is at the 128th level, and blue is at 0 intensity. Next, a control start signal "FFH" is sent followed by a group number designation signal "X03H" and color intensity designation signals "RB0H", "GB0H", and "B00H", and then a control start signal "FFH" is sent followed by a group number designation signal "X04H" and color intensity designation signals "RF0H", "GF0H", and "B00H". These control signals mean that the 20 luminaires 10 assigned group number 03 are to be lit so that red is the 176th level, green is the 176th level, and blue is the 0th intensity, and that the luminaires 10 in group 04 on the outermost circumference are to be lit so that red is the 240th level, green is the 240th level, and blue is the 0th intensity.

[0049] As described above, the four groups of luminaires 10 are set to be in one of four lighting states with a yellow lighting color and different intensities. Hereinafter, the lighting state when the color-specific intensity designation signal is "R40H", "G40H", or "B00H" will be called the "darkest yellow", when it is "R80H", "G80H", or "B00H", the lighting state when it is "third brightest yellow", when it is "RB0H", "GB0H", or "B00H", the lighting state when it is "second brightest yellow", and when it is "RF0H", "GF0H", or "B00H" will be called the "brightest yellow".

[0050] Next, after a time period specified by the program (generally one to several seconds) has elapsed, the computer 31 generates a total of four types of control signals in the same manner as above to turn on the brightest yellow at X01H, the dimmest yellow at X02H, the third brightest yellow at X03H, and the second brightest yellow at X04H, and transmits these in sequence from the infrared communication device 32 to all of the luminaires 10. After a time period specified by the program has elapsed again, the computer 31 generates a total of four types of control signals to turn on the second brightest yellow at X01H, the brightest yellow at X02H, the dimmest yellow at X03H, and the third brightest yellow at X04H, and transmits these in sequence from the infrared communication device 32 to all of the luminaires 10 in the same manner. Finally, after the time specified by the program has elapsed, the computer 31 generates a total of four control signals to light X01H with the third brightest yellow, X02H with the second brightest yellow, X03H with the brightest yellow, and X04H with the dimmest yellow, and then transmits these sequentially from the infrared communication device 32 to all of the lighting fixtures 10.

[0051] By repeating the above operations, the luminaire 10 will be illuminated in four patterns shown in the order of the upper left, upper right, lower left, and lower right of Fig. 8, and then the luminaire 10 will be illuminated in order to return to the pattern shown in the upper left. This illumination creates the movement of a yellow frame spreading from the inside to the outside.

[0052] In the above explanation, only the change in brightness of the yellow color was explained, but in actual use, it is possible to express more complex and beautiful illumination by changing the color and brightness.

[0053] (2) Second Example In terms of hardware, the luminaire and illumination system of the second embodiment has the same configuration as the first embodiment, except that the non-volatile memory (group number storage section) 14 of the luminaire 10 has multiple pages 141, 142, ... as shown in Fig. 9. One group number is stored in each of the pages 141, 142, .... Thus, multiple group numbers are stored in the non-volatile memory 14 as a whole. One group number 01, 02, ... is assigned to each of the pages 141, 142, ....

[0054] Fig. 10 shows an example of a signal generated by the PC 31 and sent by the infrared communication device 32 in the second embodiment. This signal assigns one group number corresponding to each of the multiple page numbers to each luminaire 10 that receives it (hence, one luminaire 10 has multiple group numbers as a whole), and is sent simultaneously to multiple luminaires 10 that have the same combination of page number and group number to be set. In the group number setting signal shown in Fig. 10, the page number (hereinafter referred to as Ppp) is specified by the code following the program start code "00H", and the group number (hereinafter referred to as Gnn) is written in the next code.

[0055] In the example of Fig. 10(a), the code "P01H" indicating page number 01 is transmitted, followed by the code "G03H" indicating group number 03. In the example of Fig. 10(b), the code "P02H" indicating page number 02 is transmitted. After sending 10(a) and (b), the luminaire 10 stores group number 03 on page 141 with page number 01, and group number 01 on page 142 with page number 02. In the following, the group number stored on page 141 with page number 01 is written before the " / " (slash), and the group number stored on page 142 with page number 02 is written after the " / ". In the example of FIGS. 10(a) and (b), it is "03 / 01". Note that although the number of pages is two here, it may be three or more.

[0056] In the second embodiment, as in the first embodiment, in the group number setting operation, a lamp that has successfully completed the instructed task (writing the group number for each page number) may light up, for example, a green LED for a short period of time, while a lamp in which an abnormality has occurred may light up a red LED for a long period of time.

[0057] All of the luminaires 10, each having a plurality of group numbers stored in a page of the non-volatile memory 14 in this manner, are installed at the site where the illumination will be performed. In the example shown in Fig. 11, the luminaires 10 are arranged in the same manner as in Fig. 6 for the group numbers stored in page 141 of page number 01, and the luminaires 10 are arranged so that the group numbers stored in page 142 of page number 02 are divided into four areas separated horizontally by group number.

[0058] When turning on each luminaire 10, first, as shown in FIG. 12, send the control start code "FFH" followed by the page selection code "FFH", and then send the page number "01H" (or "02H") to specify page number 01 (or 02).

[0059] Thereafter, as in the first embodiment, a control signal consisting of a control start signal, a group number designation signal, and a color-specific intensity designation signal is transmitted for each group number (see FIG. 7), thereby controlling the lighting of each luminaire 10. When page number 01 is designated, each luminaire 10 that receives the control signal operates according to the group number assigned to the page number 01, and when page number 02 is designated, operates according to the group number assigned to the page number 02. When the luminaires 10 are arranged as shown in FIG. 11, when page number 01 is designated, illumination in which a rectangular frame moves outward or inward as shown in FIG. 13A can be displayed, and when page number 02 is designated, illumination in which horizontal lines move from the bottom to the top as shown in FIG. 13B can be displayed. In this way, simply by switching the page number, illuminations with different patterns and movements can be displayed instantly, so that a variety of illuminations that do not tire the audience can be provided.

[0060] (3) Third embodiment A third embodiment of the illumination system is shown in Fig. 14 and subsequent figures. In the third embodiment, a magnetic communication receiving circuit 23 is used as the wireless communication unit of the lighting fixture 20, instead of the infrared communication receiving circuit 13 used in the first and second embodiments, as shown in Fig. 14. Magnetic communication can be used almost freely, unlike radio communication that requires authorization under the Radio Law, and AC magnetic fields can be detected inexpensively and with very low power consumption by using inexpensive coils and Hall elements that are widely used these days.

[0061] The magnetic communication receiving circuit 23 includes a coil 231 and an amplifier / demodulator circuit 232 for an AC signal obtained from the coil 231. Various types of Hall elements, magnetic resistance elements, and other magnetic detection elements can be used instead of the coil 231. The configuration of the lighting fixture 20 other than the magnetic communication receiving circuit 23 is similar to the configuration of the lighting fixture 10 in the first and second embodiments, and therefore detailed description thereof will be omitted.

[0062] 15 shows an illumination system 40 in a third embodiment. In this illumination system 40, a personal computer 41 and a magnetic communication interface 421 are wirelessly connected to each other, and a transmission loop 422 is connected to the magnetic communication interface 421. As in the first embodiment, the personal computer 41 and the magnetic communication interface 421 may be connected by wire, but connecting them wirelessly makes installation easier. A part or all of the transmission loop 422 may be buried underground. Figure 16 In the example shown in FIG. 1, the portion of the transmission loop 422 marked with the reference symbol 4221 is buried underground. The magnetic communication interface 421 and the transmission loop 422 are combined to form the magnetic communication device 42, which functions as the group number setting wireless communication device and the control information transmitting wireless communication device. By passing an AC current through the transmission loop 422, an AC signal is generated in the magnetic communication receiving circuit 23 of the luminaire 20 placed inside the transmission loop 422, and the luminaire 20 can recognize the signal by amplifying and demodulating the AC signal.

[0063] 16 shows an example of distributing control signals by magnetic communication to all of a large number of luminaires installed in a wide area, where a magnetic communication interface 421 is wirelessly connected to a personal computer 41, and a transmission loop 422 is arranged to surround the area in which the luminaires 20 are installed. Note that in this example, the personal computer 41 and the magnetic communication interface 421 may also be connected by wire, but a wireless connection makes installation easier. An AC signal is generated in the magnetic communication receiving circuit 23 inside the luminaire 20 by passing an AC current through the transmission loop 422, and the luminaire 20 receives the control signal by amplifying and demodulating the AC signal.

[0064] When installing the transmission loop 422, in places where it is difficult to place the electric wire on the ground, such as in a passageway, the electric wire can be raised to the required height with a pole or buried underground as shown in Fig. 16, so there is a high degree of freedom. Also, if the installation area is very large or is divided into blocks, it may be divided into multiple transmission loops.

[0065] The group number setting operation and the control of the operation of each luminaire 20 in the third embodiment are similar to those in the first or second embodiment except for the use of magnetic communication, and therefore a detailed description thereof will be omitted.

[0066] (4) Fourth Example (4-1) Configuration of the fourth embodiment of the lighting fixture with speaker and illumination system 17 shows one embodiment of a lamp with a speaker. This lamp with a speaker 50 has a power supply unit 11, a light-emitting unit 12, an infrared communication receiving circuit (wireless communication unit) 13, a non-volatile memory 54, a CPU circuit 55, and a sound generating unit 56. The power supply unit 11, the light-emitting unit 12, and the infrared communication receiving circuit 13 are the same as those of the lamp 10 of the first embodiment, so detailed explanations will be omitted.

[0067] The sound generating unit 56 has a speaker 561 and a sound generating circuit 562. In this embodiment, only one speaker 561 is provided per one speaker-equipped lighting fixture 50, but two or more speakers may be provided. The sound generating circuit 562 is a circuit that converts a control signal from the CPU circuit 55 into an electrical signal that causes the speaker 561 to produce sound, and has a function such as an amplifier.

[0068] The non-volatile memory 54 is structurally the same as the non-volatile memory 14 in the first embodiment, and has, as functional blocks, a group number storage unit 541 for storing group numbers and a sound data storage unit 542 for storing sound data. A plurality of sound data are stored in the sound data storage unit 542. Each sound data is composed of data of a waveform within a predetermined sounding time. A sound data number is assigned to each sound data, which is a number for distinguishing it from other sound data. Each sound data number is associated with the corresponding sound data and stored in the sound data storage unit 542. The sound data and sound data number may be transmitted from the infrared communication device 32 and received by the infrared communication receiving circuit 13 and stored in the sound data storage unit 542, or the speaker-equipped lamp 50 may be provided with a wireless or wired communication interface separate from the infrared communication receiving circuit 13, and the sound data and sound data number may be received by the communication interface and stored in the sound data storage unit 542. In particular, when using long-duration sound data such as music, it is advisable to use a communication interface capable of transmitting and receiving a larger amount of data than the infrared communication device 32 and the infrared communication receiving circuit 13.

[0069] The sounds stored as sound data in the sound data storage unit 542 include, for example, natural sounds such as the sound of waves and wind, animal voices such as insects and birds, sounds played by musical instruments, human voices (including singing voices), etc. Different sound data numbers can be assigned to different animals in the case of animal voices, different instruments in the case of musical instruments, and different parts (soprano, alto, etc.) in the case of human singing voices.

[0070] The CPU circuit 55 is structurally the same as the CPU circuit 15 in the first embodiment, and includes a power supply unit 11, a light emitting unit 12, an infrared communication receiving circuit, 13 It is a control unit that collectively controls the non-volatile memory 54 and the sound generation unit 56. As in the first embodiment, (a plurality of) control units that individually control each unit may be used.

[0071] As shown in Fig. 18, the illumination system of the fourth embodiment is composed of a plurality of speaker-equipped lighting fixtures 50, a personal computer 61, and an infrared communication device 62 having an infrared communication interface 621 and an infrared communication signal transmitter 622 and wirelessly connected to the personal computer 61. The personal computer 61 and the infrared communication device 62 are similar to the personal computer 31 and the infrared communication device 32 in the illumination system of the first embodiment, except that they generate and transmit control information related to sound in addition to light. Also, in the fourth embodiment, similar to the first embodiment shown in Fig. 3, a large number of speaker-equipped lighting fixtures 50 can be installed in a wide area, and then multiple infrared communication signal transmitters can be arranged to control all of the speaker-equipped lighting fixtures 50.

[0072] (4-2) Operation of the fourth embodiment of the lighting fixture with speaker and illumination system The operation of the speaker-equipped lamp 50 and the illumination system 60 of the fourth embodiment will be described below. In the fourth embodiment, first, an operation is performed to set a group number for each speaker-equipped lamp 50. Then, lighting and sound generation of each speaker-equipped lamp 50 are controlled to generate varied illumination and realistic sound. The operation of setting the group number is the same as the operation described in the first embodiment using Figures 4 to 6, so the explanation is omitted, and the following describes the lighting and sound generation control of each speaker-equipped lamp 50.

[0073] When each lamp with speaker 50 is turned on and a sound is generated, the following control signals are generated by the computer 61 and then transmitted from the infrared communication device 62 to all lamps with speakers 50. First, a control start signal "FFH" is followed by a group number designation signal "XnnH" that designates the group number "nn". Next, color intensity designation signals "RmmH", "GmmH" and "BmmH" that indicate the light emission intensity of red, green and blue, respectively, in hexadecimal value "mm" (actually, a value is set for each color) are sent in that order. Next, a sound designation signal "ShkH" is transmitted that designates the sound data number "hk" of the sound data to be generated.

[0074] In the case of sound data for instrumental music or vocals, different instruments or parts can be assigned to different groups, and the first number "h" in the sound data number "hk" can be assigned the group number (the last digits), and the last number "k" can be assigned the number indicating the order in which the sound data is pronounced by time.

[0075] With the operations up to this point, the transmission of control signals for lighting and sound to a lamp with a speaker 50 having one group number is completed. When subsequently transmitting a control signal to a lamp with a speaker 50 having another group number, first transmit the control start signal "FFH", and then transmit the group number designation signal, the color intensity designation signals for the three colors, and the sound designation signal. By performing this operation for all group numbers, the transmission of control signals is completed.

[0076] An example of the control signal is shown in Fig. 19. In this example, the control start signal "FFH" is followed by the group number designation signal "X01H", color intensity designation signals "R40H", "G40H" and "B00H", and sound designation signal "S11H". These control signals mean that the speaker-equipped lamp 50 with group number 01 is turned on so that red is at the 64th level of intensity, green is at the 64th level of intensity, and blue is at 0 intensity, and sound is generated by sound data with sound data number 11. Next, the control start signal "FFH", group number designation signal "X02H", color intensity designation signals "R80H", "G80H" and "B00H", and sound designation signal "S21H" are sent. Next, it sends out a control start signal "FFH", a group number designation signal "X03H", color intensity designation signals "RB0H", "GB0H" and "B00H", and a sound designation signal "S31H". Finally, it sends out a control start signal "FFH", a group number designation signal "X04H", color intensity designation signals "RF0H", "GF0H" and "B00H", and a sound designation signal "S41H".

[0077] By transmitting the control signal as shown in FIG. 19, the light emitting unit 12 of each speaker-equipped lamp 50 is set to the “darkest yellow” with red at the 64th level of intensity, green at the 64th level of intensity, and blue at the 0th level of intensity for group number 01, the “third brightest yellow” with red at the 128th level of intensity, green at the 128th level of intensity, and blue at the 0th level of intensity for group number 02, and the “third brightest yellow” with red at the 176th level of intensity, green at the 128th level of intensity, and blue at the 0th level of intensity for group number 03. Intensity , green is 176th stage Intensity The second brightest yellow, with blue at intensity 0, is assigned group number 04, with red at 240th level. Intensity , green is 240th stage Intensity The light is then lit up to the brightest yellow, with blue at an intensity of 0. This allows the audience to see the same light pattern as shown in the upper left diagram of Figure 8.

[0078] At the same time, the sound generator 56 of the speaker-equipped lighting fixture 50 emits a sound based on sound data assigned with sound data number 11 for the lighting fixture assigned with group number 01, a sound based on sound data number 21 for the lighting fixture assigned with group number 02, a sound based on sound data number 31 for the lighting fixture assigned with group number 03, and a sound based on sound data number 41 for the lighting fixture assigned with group number 04. This allows the viewer to perceive a first superimposed sound in which these four sounds originating from different positions are superimposed.

[0079] Next, the personal computer 61 and the infrared communication device 62 generate and transmit to the speaker-equipped lighting device 50 a total of four color-specific intensity designation signals, which light the brightest yellow at X01H, the darkest yellow at X02H, the third brightest yellow at X03H, and the second brightest yellow at X04H, in the same manner as above, after a time (generally one to several seconds) designated by the program has elapsed since the transmission of the first control signal. At the same time, they generate and transmit to the speaker-equipped lighting device 50 a total of four sound designation signals, which are a sound designation signal "S12H" at X01H, a sound designation signal "S22H" at X02H, a sound designation signal "S32H" at X03H, and a sound designation signal "S42H" at X04H. As a result, the audience sees the same light emission pattern as shown in the upper right diagram of FIG. 8. At the same time, the audience sees a second superimposed sound in which four sounds based on sound data with sound data numbers 12, 22, 32, and 42 are superimposed.

[0080] Furthermore, after the time period specified by the program has elapsed, the personal computer 61 and the infrared communication device 62 generate and transmit a total of four color intensity designation signals in the same manner as described above, to light the second brightest yellow at X01H, the brightest yellow at X02H, the dimmest yellow at X03H, and the third brightest yellow at X04H, and also generate and transmit a total of four sound designation signals to the speaker-equipped lighting fixture 50: a sound designation signal "S13H" at X01H, a sound designation signal "S23H" at X02H, a sound designation signal "S33H" at X03H, and a sound designation signal "S43H" at X04H. After that, the personal computer 61 and the infrared communication device 62 generate and transmit to the speaker-equipped lamp 50 a total of four color-specific intensity designation signals, which light the third brightest yellow at X01H, the second brightest yellow at X02H, the brightest yellow at X03H, and the dimmest yellow at X04H, in the same manner as described above, after the time specified by the program has elapsed, and also generate and transmit to the speaker-equipped lamp 50 a total of four sound designation signals, which are a sound designation signal "S14H" at X01H, a sound designation signal "S24H" at X02H, a sound designation signal "S34H" at X03H, and a sound designation signal "S44H" at X04H. By these operations, the viewer can see the same two light emission patterns as those shown in the lower left and lower right diagrams of FIG. 8 in sequence. At the same time, the audience hears, in order, a third overlapping sound, which is made up of four overlapping sounds from sound data assigned sound data numbers 13, 23, 33, and 43, and a fourth overlapping sound, which is made up of four overlapping sounds from sound data assigned sound data numbers 14, 24, 34, and 44.

[0081] By repeatedly executing the above operations, the speaker-equipped lamp 50 is sequentially lit in four patterns shown in the upper left, upper right, lower left, and lower right diagrams in Fig. 8, and then the speaker-equipped lamp 50 is sequentially lit so as to return to the pattern shown in the upper left diagram, repeating the illumination. In synchronization with this repetition of illumination, a first superimposed sound, a second superimposed sound, a third superimposed sound, and a fourth superimposed sound are sequentially emitted, and then a sound is generated that returns to the first superimposed sound.

[0082] When sound data is assigned to different groups with different instruments or parts, with the group number (last digit) being "h" (1-4) and the pronunciation order number being "k" (1-4), the sounds of the different instruments or vocal parts will play from the speaker-equipped lighting fixtures 50 in each group in the pronunciation order.

[0083] In the above explanation, only the change in brightness of the yellow color was explained, but in actual use, it is possible to express more complex and beautiful illumination by changing the color and brightness.

[0084] (5) Fifth Example As described above, in the fourth embodiment, the light emission by the light-emitting unit 12 and the sound generation by the sound generation unit 56 are controlled using the same group number, so that the lamps with speakers 50 that emit the same light emit the same sound. In contrast, the lamp with speakers and illumination system of the fifth embodiment has the following configuration in order to control the light emission and sound generation independently.

[0085] 20 shows the configuration of a speaker-equipped lamp 50A of the fifth embodiment. This speaker-equipped lamp 50A has a non-volatile memory 54A having the functions of a first group number storage unit 5411, a second group number storage unit 5412, and a sound data storage unit 542, instead of the non-volatile memory 54 having the functions of the group number storage unit 541 and the sound data storage unit 542 in the speaker-equipped lamp 50 of the fourth embodiment. The rest of the configuration of the speaker-equipped lamp 50A is the same as that of the speaker-equipped lamp 50 of the fourth embodiment.

[0086] The first group number is stored in the first group number storage section 5411, and the second group number is stored in the second group number storage section 5412. Both the first group number and the second group number are generated by the personal computer 61, transmitted by the infrared communication device 62, and received by the infrared communication receiving circuit 13 of the speaker-equipped lamp 50A, as described below. The first group number is a number for identifying a group of the speaker-equipped lamps 50A that cause the light-emitting unit 12 to perform the same operation, and the second group number is a number for identifying a group of the speaker-equipped lamps 50A that cause the sound-emitting unit 56 to perform the same operation.

[0087] The first and second group numbers are assigned independently to each of the speaker-equipped lamps 50A. In the example shown in Fig. 21, the speaker-equipped lamps 50A are arranged in a square lattice pattern and the first group numbers 01 to 04 (shown as "1" to "4" in the figure) are assigned concentrically to the speaker-equipped lamps 50A, while the left half is assigned the second group number 11 and the right half is assigned the second group number 12. Of course, the division into the first and second groups is not limited to this example. The number of groups in each of the first and second groups is not limited to this example (four in the former and two in the latter).

[0088] The illumination system of the fifth embodiment has, as hardware, a personal computer 61 and an infrared communication device 62 similar to those of the illumination system of the fourth embodiment shown in Fig. 18, in combination with the lamp with speaker 50A of the fifth embodiment. In this embodiment, the personal computer 61 has a function of generating a first control signal for controlling the operation of the light-emitting unit 12 for each first group number, and a second control signal for controlling the operation of the sound-producing unit 56 for each second group number. The infrared communication device 62 transmits the first control signal and the second control signal to the infrared communication receiving circuit 13 of the lamp with speaker 50A.

[0089] FIG. 22 shows an example of the first and second control signals. The first to fourth lines of the six control signals shown in the figure are first control signals for controlling the light emitting unit 12, and these are signals for controlling the light emission intensities of the red LED element 121, the green LED element 122, and the blue LED element 123 for the four first groups 01 to 04, respectively, similar to the control signals of the first embodiment (FIG. 7). The fifth and sixth lines are second control signals for controlling the sound generating unit 56, which are transmitted following the first control signal. Specifically, the second control signal controls the speaker-equipped lamp 50A to which the second group number 11 is assigned among the two second groups to emit sound 11 based on sound data to which sound data number 11 is assigned, and controls the speaker-equipped lamp 50A to which the second group number 12 is assigned to emit sound 21 based on sound data to which sound data number 21 is assigned. The first and second control signals are not limited to this example.

[0090] Upon receiving the first control signal and the second control signal, each of the speaker-equipped lamps 50A emits light from the light-emitting unit 12 in accordance with the first control signal corresponding to the first group to which the speaker-equipped lamp 50A belongs, and emits sound from the sound-emitting unit 56 in accordance with the second control signal corresponding to the second group. When the first control signal and the second control signal of the example shown in Fig. 22 are transmitted to each of the speaker-equipped lamps 50A grouped in the example shown in Fig. 21, each of the speaker-equipped lamps 50A emits light with different intensities for the first groups 01 to 04 ("1" to "4" in the figure) as shown in Fig. 23, and emits different sounds for the second groups 11, 12.

[0091] Thereafter, by transmitting a first control signal and / or a second control signal having different content, the light emission of the speaker-equipped lamps 50A of each first group and / or the sound emission of the speaker-equipped lamps 50A of each second group can be changed.

[0092] (7) Effects of each embodiment As described above, the entertainment equipment and entertainment system of each of the above embodiments use a simple and low-power wireless communication function with only a receiving function on the entertainment equipment side, making the entire entertainment system inexpensive and low-power, and allowing it to run on batteries for a long time. Also, in a large-scale full-color illumination installed widely and in large quantities, it is possible to express a variety of complex movements that visitors will not tire of. In addition, in the fourth and fifth embodiments, the speakers installed in the entertainment equipment installed widely and in large quantities are divided into multiple groups and each group produces a different sound, thereby realizing a realistic sound.

[0093] In each of the above embodiments, when used for large-scale illumination using thousands or tens of thousands of entertainment equipment, each entertainment equipment has the same hardware and software, so when writing control information, etc., it is possible to write the information collectively by simply dividing the equipment into groups, and when installing the equipment, installation is easy as it does not depend on the individual equipment as long as the equipment is in the same group.

[0094] Furthermore, even during actual use (when lit), conventional lighting fixtures each have their own identification number, and as the number of fixtures increases, the amount of communication traffic becomes enormous and high-speed communication is required. However, the entertainment equipment of this invention can be controlled collectively in groups, which significantly reduces the amount of data required, making it possible to create large-scale, dynamic illumination even with low-speed communication.

[0095] Furthermore, when a page function is provided as in the second embodiment, the pages can be switched simultaneously for all entertainment equipment, making it possible to instantly switch between a variety of illumination patterns.

[0096] (8) Modifications The present invention is not limited to the above-described embodiments, and various modifications are possible.

[0097] For example, in the above description of each embodiment, the settings of the page number, group number, and power of the red LED, green LED, and blue LED are described as 8 bits in binary, but they may be expressed in 4 bits each to increase the communication speed during use, or 8 bits and 4 bits may be appropriately combined. The code system in the above embodiment is an example and does not affect the effect of the invention.

[0098] In each of the above embodiments, a solar panel and a secondary battery are used for the power supply, but a simple secondary battery or a primary battery may also be used. Power may be supplied via a wire. In addition, in each of the above embodiments, an LED is used as the light source, but a light source other than an LED may also be used. In each of the above embodiments, infrared communication (first to fourth embodiments) or magnetic communication (third embodiment) is used for the wireless communication device, but a wireless communication device other than these may also be used.

[0099] In the second embodiment, the lighting fixture 10 (without a speaker) is controlled using the page function, but the lighting fixture with speaker 50 may also be controlled using the page function as in the second embodiment. In this case, first, as a preparation step, a group number for each page number corresponding to the page is stored in each page (corresponding to pages 141, 142, etc. in the second embodiment) of the non-volatile memory 54 of each lighting fixture with speaker 50 using wireless communication as in the example shown in FIG. 10 in the second embodiment. Then, when illumination is performed, the page number is first transmitted to the lighting fixture with speaker 50 using wireless communication as in the example shown in FIG. 12 in the second embodiment. As a result, each lighting fixture with speaker 50 reads out the group number stored in the received page number. Thereafter, based on the group number, as in the fourth embodiment, each lighting fixture with speaker 50 receives a signal of control information including the operation of the light-emitting unit 12 and the sound-producing unit 56 designated by the group number via wireless communication, and then performs those operations.
