JP 2003-36981 A

  Pen lights equipped with wireless LAN are handed over to the audience, the color of the pen lights on the audience seats is controlled, the audience seats are dyed in any color, and any images or patterns are drawn on the audience seats to produce the event It is considered to participate in. However, penlights equipped with a wireless LAN have high hurdles in terms of cost and management, and are only used experimentally at events such as concerts.

  According to one embodiment of the present invention, a light-emitting unit that outputs light of a plurality of colors, a memory that stores a first pattern including the order of a plurality of colors output from the light-emitting unit, and a first signal are output. The light emitting device includes a control unit that randomly selects a start position of a color order and repeatedly outputs light of a plurality of colors in order from the light emitting unit.

  Controlling the colors emitted by the light emitting devices held by the audience in synchronization is, for example, broadcasting (broadcasting) a signal for switching colors or a signal for switching patterns defining the order of color development from the transmitter wirelessly. Is possible. Controlling the color of the light emitting device by dividing the spectator seat into a certain area means that a plurality of transmitters with outputs sufficient to cover the area and a plurality of identification information (ID) corresponding to each transmitter are set. This can be realized in combination with the light emitting device.

  Furthermore, the light emitting device of the present invention randomly selects the start position of the order of colors included in the first pattern preset in the memory, and sequentially outputs light of a plurality of colors from the light emitting unit according to the order. Output repeatedly. Therefore, it is possible to control so that the colors emitted by the light emitting devices held by nearby spectators are not the same as much as possible. In other words, when light of an integer n different colors is switched and output from the light emitting device, if a color is selected randomly each time the color is switched, the light emitting devices of adjacent spectators always have the same color with a probability of 1 / n. May be selected. On the other hand, in the light emitting device of the present invention, if the same color is not selected when starting, there is basically no possibility that the same color will be selected thereafter. Therefore, the light of the color which does not always overlap can be output with high probability from the light emitting device which the adjacent audience has.

  Furthermore, if a color is randomly selected each time the color is switched, there is always a possibility that the same color or a color with a similar hue may be selected. There is a possibility that you can not enjoy the change. On the other hand, in the case of the light emitting device of the present invention, by setting an order in which colors with different hues are arranged in order as the first pattern, the colors are different from those of other people's light emitting devices, one after another. You can enjoy your own light emitting device emitting light in different colors.

  In order to actively manage the light emitting devices held by adjacent spectators so that they do not develop the same color, it is necessary to set different identification information or addresses for the light emitting devices and to manage the location of the light emitting devices. That is, it is necessary to prepare a light-emitting device including a wireless LAN transmission / reception unit and a light-emitting device set with a different ID, and to manage the location of the audience using them. Therefore, the cost of the light emitting device increases, and the burden on the organizer of the concert or event increases.

  On the other hand, the light emitting device of the present invention only needs to broadcast the first signal serving as a trigger for performing random output. It is desirable that the light emitting device further includes a receiving unit that receives the broadcast first signal.

  A plurality of patterns including the first pattern can be stored in the memory. When the control unit receives the second signal, the control unit may include a function of outputting the pattern associated with the second signal among the plurality of patterns from the light emitting unit in the order of the pattern from the specific start position. Good. By transmitting the second signal, light of a plurality of colors can be output in synchronization from the plurality of light emitting devices.

  Another aspect of the present invention is a system including a plurality of light-emitting devices and a transmission device that transmits a first signal to the plurality of light-emitting devices.

Another aspect of the present invention is a method for controlling a light emitting device. The light emitting device includes a light emitting unit that outputs light of a plurality of colors, a memory that stores a color pattern output from the light emitting unit, and a control unit that controls the colors output from the light emitting unit. The control method includes the following steps.
The control unit randomly selects the start position of the sequence of the plurality of colors stored in the memory according to the first signal;
-Output multiple colors of light repeatedly in order from the light emitting unit.

  When the second signal is received, the control method may include a step of outputting a pattern associated with the second signal among the plurality of patterns from the light emitting unit in the order of the pattern from a specific start position. Good.

  This control method is provided by being recorded on a suitable recording medium such as a flash memory as a program (program product) executed by a CPU incorporated in the light emitting device, or provided via a computer network such as the Internet. Can do.

  FIG. 1 shows an outline of a system including a plurality of light emitting devices. The system 1 includes a portable small light-emitting device 10 called a penlight, a transmitter 30 that transmits a signal S to the plurality of light-emitting devices 10, and an operation that controls the signal S output from the transmitter 30. Table 35 is included. In the following description, a penlight type light emitting device (penlight) 10 that is slender and is shaken by a hand like a pen or a stick as a whole will be described as an example. However, the light emitting device is generally disc-shaped and is held by hand. It may be provided with an opening, may be fan-shaped or fan-shaped like a fan or fan, and may be worn on an arm like a bracelet It may be worn on the body other than the hand or arm, like a hat, hair band or headband. The light emitting part of the light emitting device 10 may have a bar shape, a disk shape, a fan shape, or other various shapes.

  The plurality of penlights 10 are held by audience members 3 around the stage 2 and moved or swung, so that the audience members 3 can play the contents on the stage 2 such as concerts and plays. Can participate from. The color of light output from the plurality of penlights 10, the timing of output (light emission), and the light emission pattern are controlled by a signal S transmitted from the transmitter 30. The reach of the signal by radio depends on the output of the transmitter 30, the conditions of the venue, and the environment, but it is desirable to cover the entire passenger seat 3 or cover the range in which the passenger seat 3 is divided into several areas. For example, the reach distance of the signal can be set to about 100 m to 200 m.

  FIG. 2 shows a schematic configuration of the penlight 10. The penlight 10 as a whole has a columnar shape or a rod shape, and an example of the size is a total length of about 250 mm or less and a diameter of about 25 mm or less. The penlight 10 includes an upper light emitting portion 11 and a lower grip portion 12. The light emitting portion 11 is made of a transparent or milky white light-transmitting and lightweight resinous member such as acrylic, and a receiving antenna 19 is installed therein. The grip portion 12 is made of an opaque resin member, and internally includes a light emitting unit 13 that outputs light from the light emitting portion 11 and a receiving unit 14 that receives a signal S broadcast (transmitted) from the transmitter 30. A memory 16, a control unit 15, and a battery 17.

  The light emitting unit 13 is an LED type, and an example is an LED unit with a lens in which LEDs of RGB colors are packaged. The light emitting unit 13 may include a plurality of LED units, for example, RGB color LED units, or a plurality of LED units dispersed in the light emitting portion 11.

  An example of the receiving unit 14 can receive a signal transmitted from the transmitter 30 corresponding to the low power radio or the specific low power radio. In this example, a receiver of 315 MHz digital amplitude modulation is adopted. An example of the memory 16 is a flash memory, in which a plurality of patterns (light emission patterns) P including information such as an order of a plurality of colors output by the light emitting unit 13 and intervals are stored in advance. The penlight 10 may be a type in which a memory 16 in which a plurality of light emission patterns are recorded in advance is set, or an interface for writing data in the memory 16 such as a USB may be provided.

  The control unit 15 is a processor, such as a CPU or a microcomputer, that functions by loading a program from the memory 16 or a memory in which another program is stored. The control unit 15 decodes the signal S received by the receiving unit 14, selects a pattern designated by the signal S from the light emission patterns P stored in the memory 16, and outputs the pattern from the light emission unit 13 (first 21) and a function (second function) 22 for selecting the start position of the light emission pattern P at random and outputting it from the light emitting unit 13 if the signal S is a random output.

  FIG. 3 shows examples of several light emission patterns P stored in the memory 16. The first light emission pattern (first pattern) P1 is a strobe pattern, and light of each color of red R, cyan C, yellow Y, magenta M, green G, blue B, and white W is set to 0 for 0.05 second. This is a pattern in which the light emitting unit 13 sequentially outputs from the head, that is, red R, with an interval of 1 second. When receiving the signal S01, the first function 21 of the control unit 15 outputs the light emission pattern P1 from the light emission unit 13 in order from the first red R, and repeats the output of the light emission pattern P1 until the next signal S is received. .

  When the first function 21 receives the signal S01, the first function 21 outputs light of a predetermined color in the order according to the order of the pattern P1 from the red R, but when the control unit 15 receives another signal, There may be provided a function of outputting light of a predetermined color corresponding to the signal, for example, light of a predetermined color from yellow Y in the order according to the order of the pattern P1. The same applies to the other light emission patterns.

  The second light emission pattern P2 is a strobe pattern, and white W is repeated for 0.05 seconds at intervals of 0.1 second, and output from the light emitting unit 13 is performed. When receiving the signal S02, the first function 21 of the control unit 15 repeatedly outputs the light emission pattern P2 from the light emission unit 13 until the next signal S is received. The processing after receiving the signal S is the same for other light emission patterns.

  The third light emission pattern P3, the fourth light emission pattern P4, and the fifth light emission pattern P5 are cut patterns, and light of each color of red R, cyan C, yellow Y, magenta M, green G, blue B, and white W. Are output from the light emitting unit 13 in order of 0.3 second, 0.2 second, and 0.1 second from the head, that is, red R, without an interval. When receiving the signals S03, S04, and S05, the first function 21 of the control unit 15 repeatedly outputs the light emission patterns P3 to P5 corresponding to the respective signals from the light emission unit 13.

  The sixth light emission pattern P6 and the seventh light emission pattern P7 are fade patterns (gradation patterns), and light of each color of red R, cyan C, yellow Y, magenta M, green G, blue B, and white W and the off state. Are output from the light emitting unit 13 in turn in a fade loop of 0.15 second and 0.4 second steps from the head, that is, red R, without an interval. When the first function 21 of the control unit 15 receives the signals S03, S04, and S05, the fade loop repeatedly outputs the light emission patterns P3 to P5 corresponding to the respective signals from the light emission unit 13.

  FIG. 4 shows processing and output when a signal (first signal) S11 for instructing random output is received. When the second function 22 of the control unit 15 receives the random output signal S11, as shown in FIG. 4A, the start position of the light emission pattern P1, that is, the color to be started is selected at random, and the second function 22 shown in FIG. As shown in b), light of a predetermined color is output from the light emitting unit 13 in the order according to the order of the light emission pattern P1 from the randomly selected start position (color).

  For example, as shown in FIG. 4A, when the pen light 10 of the user # 1 receives the first signal S11, the blue light B is selected as the color to start, and the pen light 10 of the user # 2 When the first signal S11 is received, the yellow light Y is selected as the starting color, and the penlight 10 of the user # 3 selects white W as the starting color when the first signal S11 is received.

  As a result, as shown in FIG. 4B, the penlight 10 of the user # 1 emits light of each color of blue B, white W, red R, cyan C, yellow Y, magenta M, and green G to the user # 1. The second penlight 10 is yellow Y, magenta M, green G, blue B, white W, red R, and cyan C, and the user # 3 penlight 10 is white W, red R, Light of each color of cyan C, yellow Y, magenta M, green G and blue B is repeatedly output in substantially synchronized manner. Therefore, if the color (start position, start color) of the timing ts when the signal # 11 is received and the light emission pattern P1 is started is different, the colors output from the penlight 10 of the user # 1 to the user # 3 are halfway. It will never be the same. For this reason, the penlight 10 of each user # 1 to # 3 emits light in a substantially random color.

  When the second function 22 of the control unit 15 receives a random output signal corresponding to each of the other light emission patterns P3 to P7, except for the light emission pattern P2 that repeats the white W, the same as above. In addition, the starting position (color) is selected at random, and the light emitting unit 13 is controlled based on the order and specifications (light emission interval, interval, fade step) of each pattern.

  In order to control the light emission colors of the penlights to be different (uneven), that is, to prevent the light emission colors of the penlights of adjacent spectators from overlapping, prepare multiple types of penlights with different frequencies and IDs, It was thought to distribute while managing the position of the audience in the venue. Alternatively, it has been studied to distribute penlights equipped with a wireless LAN interface to the audience at a predetermined location in the venue and manage the emission color by address.

  For example, if the light emission color is changed in units of five adjacent people, it is necessary to prepare penlights each having five IDs, and each ID is 2,000 even in a 10,000 person venue. Even if the ID is changed by firmware or the like, if the mass production is performed on a chip-on-board, there are five kinds of mass production effects, and the operation management of handing over a penlight with a different ID to an appropriate audience becomes very troublesome.

  In the case of the penlight 10 of this example, when the signal S11 for causing the penlight 10 to emit light randomly is received, the start position of the light emission pattern P11 is randomly selected by the program. For this reason, even if the penlight 10 on the receiving side is the same mass-produced product, if the start position is different, the penlights 10 of the adjacent audience will not overlap with each other, and the penlights 10 of the adjacent audience will not overlap. Can be controlled to be uneven.

  Further, if the individual colors of the light emitting pattern are simply randomized, there is always a possibility that the adjacent penlights may be covered with colors or the hues may be close to each other, and the random coloring effect is reduced. On the other hand, in the case of the penlight 10 of the present example, the hue of the color at each step of discoloration is separated. For example, not only the above pattern but also red R, white W, blue B, yellow Y, magenta M, green A random effect can be drawn by setting the arrangement (order) of G, cyan C, and the like. Of course, the light emission color itself and the color order are not limited to the above, and can be freely set in advance according to the taste of the concert organizer or the like.

  In addition, a plurality of patterns of different colors are stored in the memory 16 in advance, and a plurality of penlights 10 select a desired pattern in accordance with a signal, and each penlight 10 has a start position (start color). It is possible to select at random. By determining the discoloration pattern and making the start position random, the emission color of each penlight 10 is not random, but when looking at a plurality of penlights 10, each penlight 10 is random. It can produce as if it is emitting light in color.

  Further, with respect to the penlight 10, the light emission colors of the plurality of penlights 10 can be obtained only by preparing the penlight 10 having only one ID, no ID, or only an ID indicating the association with the transmitter 30 in one venue. Can be controlled randomly. Therefore, it is not necessary to transmit a signal for controlling the light emission pattern to each penlight 10, and the transmitter 30 simply transmits a signal for controlling the light emission pattern to a plurality of penlights 10 in the venue ( Broadcast). For this reason, the transmitter 30 may be a low-power radio device, and the penlight 10 only needs to include the receiving unit 14 that can receive a signal transmitted by the low-power radio device. Therefore, the penlight 10 and the transmitter 30 can be prepared at an extremely low cost, and the system 1 for effect control of the audience seat (audience) can be constructed at a low cost.

  FIG. 5 is a flowchart showing an outline of control of the penlight 10. When the signal S broadcast in the hall is received in step 51, it is confirmed whether or not the ID included in the signal S matches the ID attached to the penlight 10 in step 52. The signal being broadcast in the venue may be other uses or wireless communication between other devices. In addition, as will be described later, it is also possible to control the presentation of the audience seats by dividing the venue into a plurality of areas. In that case, a plurality of transmitters 30 and penlights 10 each having an ID corresponding thereto are used. It is desirable.

  If the IDs of the received signals S match, it is determined in step 53 whether or not the signals are for random output. In the case of a signal for instructing random output, for example, signal S11, the second function 22 of the control unit 15 randomly selects the start position of the first light emission pattern P1 in step 54, and randomly selects in step 55. Light of a predetermined color is output from the light emitting unit 13 in the order of the first light emission pattern P1 from the started position.

  If the signal is not a signal indicating random output, the first function 21 of the control unit 15 emits light in the order of the pattern selected by the signal S from the start position predetermined in step 55 (usually from the first color). The unit 13 outputs light of a predetermined color.

  FIG. 6 shows a different system 1 for the audience seat effect. In this production system 1, a plurality of transmitters (broadcasting devices) 30 are arranged in a passenger seat 3 at predetermined intervals, and pens each having an ID corresponding to the transmitter 30 around each transmitter 30. Distribute the light 10 to the audience. By outputting a common signal S from the plurality of transmitters 30, the emission color of the penlight 10 in the entire venue can be controlled in common. By outputting different signals S from the transmitter 30 here, the emission color of the penlight 10 in the venue can be individually and independently controlled by dividing it into a plurality of areas 5 centered on the transmitter 30.

  As described above, the light-emitting device 10 is not limited to the penlight type, and may be anything that can be held or worn by the audience. In this example, the light emitting device 10 supplies a trigger signal for selecting a light emission pattern from the outside wirelessly. However, the light emitting device 10 has a built-in clock and timer, and the trigger signal is internally received at a common timing. May be supplied to the control unit. It is also possible to provide the light emitting device 10 with a switch that can be operated by a user or a spectator so that the spectator can select a light emission pattern by himself / herself.
