The receiver receives a signal, and based on color data transmitted together with its own address, the LED drive control circuit causes the red, green, and blue light emitting sections to emit light, and the pen torch of the auditorium displays an image equivalent to an image displayed on the screen of the personal computer.

Disclosure of Invention

An apparatus is required which can enjoy highly entertaining light emitting processes at a concert hall or the like.

One embodiment of the present invention is a portable light-emitting device, such as a light-emitting or illuminating device such as a pen torch having a light-emitting portion and a grip portion connected to the light-emitting portion, a communication terminal including a display portion for generating light such as a smart phone, a wearable terminal, or the like. The light emitting device has: a short-range wireless communication unit for transmitting and receiving a light-emitting mode with another light-emitting device; and a switching unit that starts control of the light-emitting device according to the light-emission pattern received by the short-range wireless communication unit, in accordance with a switching instruction caused by at least one of an activity using the light-emitting device and an activity using another light-emitting device.

Such a light-emitting device is configured to give a switching instruction to control the light-emitting device in the same light-emitting mode as other light-emitting devices when the other light-emitting devices enter the communication range of the short-range wireless communication unit and the user holding the light-emitting device or the other users holding the other light-emitting devices perform some kind of activity. For example, when the light emitting section of the light emitting device is in an OFF state, and another light emitting device is emitting light in a predetermined color or display mode, the light emitting device starts emitting light in the same color or display mode as the other light emitting device by making the light emitting device contact with the other light emitting device, performing an action (event, performance, or presentation) such as throwing light, or performing an action such as extracting light by the light emitting device. When the light-emitting device is brought into contact with another different light-emitting device next to the light-emitting device or a light is projected to the next light-emitting device, the next light-emitting device emits light in the same color or display mode. Therefore, the plurality of light emitting devices can be successively caused to emit light as in torch relay, and a highly entertaining light emitting process can be enjoyed among a large number of users.

The light emission pattern is not limited to ON (ON) of the lighting light emitting section, but may be off of the lighting light emitting section, and may be a display mode including a color of the light emitting section. The light emitting device can transmit a light emitting mode in which the light emitting section is turned off when the light emitting section is turned on, and can transmit a display of a different display or color when the light emitting section is in a display or lighting state. The light-emitting device may further include a memory that stores the received light-emitting pattern, and a transmission unit that starts transmission of the light-emitting pattern stored in the memory by the short-range wireless communication unit in accordance with the switching instruction.

The short-range wireless communication means (proximity communication means) may be short-range wireless communication means (NFC) such as Bluetooth (registered trademark) or short-range optical communication means such as visible light communication or infrared communication, and it is desirable that data can be transmitted and received between devices in a range visible to the eyes or in a range reachable by the hand.

The light-emitting device may also have a first detection unit that issues a switching instruction (switching signal) by contacting with another light-emitting device. In addition, the light-emitting device may have a sensor that detects the movement of the light-emitting device and a second detection unit that generates a switching instruction when the movement using the light-emitting device is detected by the sensor. The light emitting device may further include a switching transmission unit that transmits a switching instruction via the short-range wireless communication unit. Examples of the sensor for detecting the motion of the light emitting device include an acceleration sensor and a magnetic sensor, and the sensor may be capable of detecting an action (motion) such as throwing light to another light emitting device using the light emitting device or detecting a performance of receiving or extracting light from another light emitting device. The user can turn on or off the other light emitting devices by touching the light emitting devices with each other such as a torch or by performing an operation such as throwing a fire or a light.

The light-emitting device may further include a unit for setting a new light-emitting mode. The lighting pattern communicated to the other lighting devices can be made by the user.

The light-emitting device may include: a long-distance wireless communication unit that receives information transmitted from a remote location beyond a communication range of the short-distance wireless communication unit; and a control unit that switches the operation of the light-emitting device according to the operation mode received by the long-distance wireless communication unit. The control unit may also include a function of receiving the light emission pattern transmitted from the remote wireless communication unit. The operation mode may also include a transfer mode for controlling the light emitting device according to the received light emitting mode. The operation of the plurality of light emitting devices can be collectively controlled by remote wireless communication. For example, light emitting devices held by a plurality of users in a field can be temporarily turned off by wireless operation, and an organizer ignites (lights) a device of an appropriate user by using a device as an ignition torch, and the device emits light to propagate to the surroundings as torch force. In addition, instead of the control such as the torch relay, control such as changing the display (light emission) of the devices of a plurality of users at the same time may be performed.

Another aspect of the present invention is a system including a plurality of the light-emitting devices described above. The system also has a system control unit that transmits information received by the light emitting device through the long-distance wireless communication unit.

Another embodiment of the present invention is a method for controlling a portable lighting device, including the following steps.

1. The light emission pattern is transmitted and received to and from other light emitting devices through the short-range wireless communication unit.

2. Control of the light-emitting device according to the light-emitting pattern received by the short-range wireless communication unit is started in accordance with a switching instruction caused by at least one of an activity using the light-emitting device and an activity using another light-emitting device.

The control method may further include: storing the received light emission pattern in a memory; and starting transmission of the light emission pattern stored in the memory by the short-range wireless communication unit according to the switching instruction.

The control method may further include: sending a switching indication by contacting with other light emitting devices; and/or generating a switching instruction when an activity using the light emitting device is detected by a sensor detecting a motion of the light emitting device.

Detailed Description

A pen torch is shown in fig. 1 as an example of the light emitting device. The pen torch 1 is formed in a thin cylindrical or rod shape as a whole, and has a light emitting section 10 in an upper half portion and a handle (grip section) 20 connected to the light emitting section 10 in a lower half portion. The light emitting unit 10 includes a translucent or transparent case 11, a light emitting element housed inside the case 11, an LED 12 in this example, and a light receiving and emitting unit 15 for short-range communication (very short-range communication). An example of the near field communication method is visible light communication or infrared communication.

Fig. 2 (a) and (b) show an example of the light receiving and emitting unit 15. The light receiving and emitting unit 15 for transmitting and receiving information includes: a sensor matrix 17 including a photosensor for receiving light and emitting light and a light-emitting element (an LED for visible light communication or an LED for infrared light communication); and a reflector 18 that inputs visible light or infrared light as a communication medium to the sensor matrix 17 or outputs visible light or infrared light from the sensor matrix 17. By adjusting the sensitivity of the photoelectric sensors of the sensor matrix 17 and the output of the light-emitting element for communication, the light-receiving and light-emitting unit 15 performs communication limited to a distance of about several tens of centimeters that can be reached by extending a hand. In a system in which light is transmitted by touch, it is desirable that the communication distance of the light receiving and emitting unit 15 is in the range of 20cm to 100 cm. In a system in which lights are thrown onto each other, it is desirable that the communication distance of the light receiving and emitting unit 15 is a distance that can be visually recognized, which is about several meters to several tens of meters. For example, the communicable distance of the light receiving and emitting unit 15 can be adjusted by controlling the sensitivity of the sensor matrix 17.

As a different example of the light receiving and emitting unit 15, as shown in fig. 2 (b), a plurality of sensor units 16 including a photosensor for receiving light and emitting light and an LED are arranged around the light receiving and emitting unit. The light receiving and emitting unit 15 shown in fig. 2 (a) and (b) is of the following type: it is possible to communicate approximately equally with other pen torches 1 in all directions of the pen torch 1 around the axis. The light receiving/emitting unit 15 may be a short-range wireless communication unit having directivity, and may be configured to allow communication in the axial direction of the pen torch 1, for example. Other pen flashers 1 can be designated for communication. Further, the communicable distance (communication range) may have a specific distribution, and it is also possible to designate a specific pen torch 1 for communication if the pen torch 1 is far away, and to communicate with a relatively small directivity if the pen torch 1 is near.

As the light emitting element for visible light communication, an LED 12 that lights (emits light, develops color) the housing 11 of the light emitting unit 10 may be used. The near field communication system that can be mounted on the pen torch 1 is not limited to visible light communication and infrared communication, and may be wireless communication using a weak radio wave (NFC, ZigBee, or the like), or communication using a different medium such as a sound wave.

The pen torch 1 further includes: a short-range wireless communication means (short-range communication means) 21 for transmitting and receiving information (data) by the light receiving and emitting means 15; a touch sensor (touch detection unit) 22; a driving unit (LED driver) 23 that controls the light-emitting LEDs 12; and a wireless communication unit 25 that communicates with a remote place of the near field communication unit using a radio wave of an appropriate frequency band. An example of the touch sensor 22 is an acceleration sensor (G sensor), a vibration switch, an inductive switch (combination of a reed switch and an electromagnetic coil), a magnetic sensor, as long as it can sense that the pen torch 1 touches other pen torches or a different object (human body). The touch sensor 22 in this example is an acceleration sensor and also functions as an activity detection sensor (performance detection sensor) that detects the movement of the grip portion 20.

An example of the wireless communication unit 25 is a wireless communication unit having a communicable range of about 10m to 100m or more, such as a wireless LAN or Wi-Fi. The wireless communication unit 25 may be any unit as long as it can exchange information at a relatively far distance (long distance) from the communicable range of the short-range wireless communication unit 21.

The pen torch 1 further comprises a CPU 30, a memory 50 and a battery 40. A program (program product) 59 executed by the CPU 30 is stored in the memory 50, and the CPU 30 operates as a control unit having various functions by executing the program 59. One of the functions realized by the CPU 30 is a function of controlling light emission (output) of the light emitting unit 10, specifically, the LED 12, in accordance with the light emission pattern M. Specifically, the CPU (control unit) 30 includes: a first function 31 for controlling the light emitting unit 10 according to the light emitting pattern M acquired by the short-range communication unit 21; a second function 32 for controlling the light emitting unit 10 according to the light emitting pattern M acquired by the wireless communication unit 25; and an activity detection unit 90 that detects an activity and outputs a switching instruction (switching signal, operation instruction) S1 to control the first function 31.

In the present specification, the light emission pattern indicates information (data) for controlling or defining the method, pattern, mode, color, order, and the like of light emission of the pen type torch 1 (the light emitting section 10 of the pen type torch 1). The light emission pattern may be transmitted by numerical information (light emission ID) or a command including a character, and may be any appropriate information (data) that can be interpreted by another pen torch.

The activity detection unit 90 includes: touch detection means (first detection means) 91 for detecting that the pen torch 1 touches another pen torch 1 by the acceleration sensor 22 and outputting a switching instruction S1; and a second detection unit 92 that detects that the user has performed an action (movement, performance) of moving the pen torch 1 to control the light (light emission) of the pen torch 1 or other pen torch 1, and issues a switching instruction S1.

The second detection unit 92 includes: a third detection unit 93 that detects that the user moves the pen torch 1 in a manner of receiving light or extracting light to control the pen torch 1 (to control the movement, internal motion indication, internal factors of the own pen torch 1); and a fourth detecting unit 94 that detects that the user moves the pen torch 1 in such a manner as to throw a light or throw the pen torch itself to control the other pen torch 1 (control the movement of the other pen torch 1, external motion indication, external factor).

The activity detection unit 90 further includes: switching instruction transmitting means (switching instruction transmitting means) 95 for transmitting (transmitting) a switching instruction (switching signal) S1 via the near-field communication means 21 when the fourth detecting means 94 detects the control of the movement of the other pen torch 1; and a switching instruction receiving unit 96 that receives a switching instruction S1 from the other pen torch 1 through the near field communication unit 21.

The light emission pattern M (light emission ID) reflected on the light emission unit 10 by the switching instruction S1 includes a plurality of IDs specifying a plurality of display modes including turning on/off (lighting on/off) the light emission unit 10. The display modes controlled according to the light emission pattern M include white lighting, lighting with a predetermined color, repeatedly displaying a plurality of colors in a predetermined algorithm or at random, or fading in and out at the time of color rendering switching. The light emission pattern M (light emission ID) may be any pattern as long as it can specify the state (operation, display, control) that can be realized by the LED 12 and the driving unit 23 of the light emitting unit 10. The light emission pattern M including any one of the IDs indicating the plurality of display modes is provided or transmitted by the communication unit 21 or 25, and the light emitting device 1 emits light in accordance with the light emission pattern M transmitted by the switching instruction S1. The light-emitting device 1 further includes an interface 39 capable of setting a light-emitting ID by a user, and a light-emitting pattern M desired by the user can be set in the memory 50.

The first function (first function unit, first unit) 31 includes: a first light emission pattern reception function (first light emission pattern reception unit) 33 that stores the light emission pattern M received by the near field communication unit 21 in the memory 50 as a light emission pattern to be emitted next (received light emission pattern, next light emission pattern) M2; and a first switching function (first switching unit) 34 that starts control of the light emitting portion 10 in accordance with the received light emission pattern M2 to change the manner of light emission of the light emitting portion 10. When the motion detection unit 90 detects a motion and outputs a switching instruction S1 as an operation instruction, the first switching unit 34 sets the next light emission mode M2 to the light emission mode M1 in operation to control the light emitting unit 10. The first switching unit 34 includes a function as a transmission function (transmission unit) that outputs information including the light emission pattern M1 during operation by the short-range wireless communication unit 21 at the same time or in tandem.

That is, the pen torch (light emitting device) 1 includes the short-range wireless communication means 21 and the control means 30, and the control means 30 controls the operation of the light emitting section 10 when detecting an operation instruction by the movement of another device. The control unit 30 includes: a function 33 that, when the short-range wireless communication unit 21 receives first information including the light emission pattern M in operation at the light emission unit of the other device, stores the received light emission pattern in the memory 50; and a first function 31 for controlling the light emitting unit 10 of the device 1 in accordance with the received light emission pattern when the motion detection means (external operation detection means) 90 detects contact or the like with another device, and outputting information including the light emission pattern M in operation via the short-range wireless communication means 21.

The second function (second function unit, second unit) 32 includes: a second switching function (second switching means, wireless control function, wireless control means) 35 for controlling the light emitting unit 10 using the light emission pattern M received by the wireless communication means 25 as the light emission pattern M1 during operation; and a third function (third means) 36 for controlling switching of the operation of the light emitting unit 10 in accordance with a switching instruction S1 output by the motion detection means 90 detecting motion. The third function 36 includes: a second light emission pattern receiving function 37 that saves the light emission pattern M received through the wireless communication unit 25 in the memory 50 as a light emission pattern to be emitted next (received light emission pattern, next light emission pattern) M2; and a third switching function (third switching unit) 38 that controls the light emitting unit 10 by setting the next light emitting mode M2 to the light emitting mode M1 in operation when the activity is detected by the activity detecting unit 90.

That is, the second information received through the wireless communication unit 25 may also contain the next light emission pattern M2 to be executed later. The second functional unit 32 includes: a function 37, if the received second information contains the next light emission pattern M2, the function 37 saves the next light emission pattern M2 in the memory 50; and a third switching function 38 for controlling the light emitting part 10 of the pen torch 1 by pressing one light emitting pattern M2 when the motion detection means 90 detects contact with another device or other motion. The user of each pen torch 1 can change the operation of the light emitting part 10 of the other pen torch 1 by touching or touching the pen torch 1 or by performing some operation while holding the grip part 20 of the pen torch 1. In addition, it is possible to enjoy a change in color development or display caused by the action of tapping the pen torch 1 by itself or making contact with the pen torch 1 of another user.

Fig. 3 shows the drawing out of the activity detection unit 90 indicating the action of the pen torch 1 by the switching instruction S1. The activity detecting unit 90 supplies the switching instruction S1 to the first switching unit 34 and the third switching unit 38 in accordance with the prescribed activity using the pen torch 1 and the prescribed activity using the other (other person' S) pen torch 1. When the acceleration sensor 22 detects a touch (contact) with the pen torch 1 of another person, the touch detection unit 91 outputs a switching instruction S1. The touch detection unit 91 outputs the switching signal S1 regardless of whether the user of the pen torch 1 touches the pen torch 1 of another person by moving, or the other person moves, or both of them move to detect the touch.

When it is recognized (detected) by the acceleration sensor 22 that the user moves his or her pen torch 1, for example, in such a manner that light (inflammation) is received or extracted from the light emitting part 10 of the pen torch 1 of the other side, the third detection unit 93 outputs a switching instruction S1 to control the light emitting part 10 of the pen torch 1 of the other side.

When the acceleration sensor 22 detects a movement in which the user grips the grip portion 20 and throws or throws the pen torch 1 so that the light emitting portion 10 faces the other, the fourth detection means 94 outputs a switching instruction S1 to the switching instruction transmission means (switching instruction transmission means) 95. The movement of the screen, in which the light (fire) of the light emitting section 10 is supposed to fly toward the opposite pen torch 1, can be captured by the acceleration sensor 22 as a sudden acceleration change of the handle 20. Further, the motion detected by the motion detecting unit 90 is an example, and is not limited thereto.

When the fourth detection unit 94 detects a motion indicating the motion of the pen torch 1 of another person, the switching instruction transmission unit 95 transmits information (first information, motion command, command) 98 including the switching instruction (motion instruction) S1 to the other pen torch 1 via the short-range wireless communication unit 21. When receiving the action command 98 from the other pen torch 1 through the short range wireless communication unit 21, the switching instruction receiving unit 96 supplies the switching instruction S1 to the first switching unit 34 and the third switching unit 38.

An example of a control method of the pen torch 1 is shown in fig. 4. The control method is provided as a program 59, and is executed by being loaded to the CPU 30. In step 61, the short-range communication unit 21 receives the information, and if the information (first information) including the light emission pattern M is included in step 62, the light emission pattern M received by the first light emission pattern receiving unit 33 is stored as the next light emission pattern M2 in the memory 50 in step 63. The light emission pattern M received by the proximity communication unit 21 is a light emission pattern M in the operation of another pen torch 1 existing in a distance where the proximity communication unit 21 can communicate.

If the information received by the close range communication unit 21 contains the switching instruction S1 in step 64, the switching instruction receiving unit 96 outputs a switching instruction S1 in step 65. In step 66, if the motion detection unit 90 detects a touch, a switching instruction S1 is output. In addition, in step S70, if the activity detection unit 90 detects an activity of operating the own pen torch 1, a switching instruction S1 is output. In accordance with the switching instruction S1, the first switching unit 34 or the third switching unit 38 sets the next light emission pattern M2 stored in the memory 50 to the light emission pattern M1 in operation to control the light emitting section 10 in step 67. For example, if the received light emission pattern M2 is a pattern in which the light emission section 10 emits light as in the case of inflammation, the light emission pattern M2 received by touching another pen torch 1 is set to the light emission pattern M1 in operation, and the light emission section 10 displays the color and the wobble of inflammation.

If the short-range communication means 21 is brought into a communication-enabled state in step 68, the first switching means 34 transmits information (communication packet) for short-range communication including the light emission pattern M1 in operation to other surrounding pen flashers 1 in step 69.

When the activity detection unit 90 detects the activity of operating the pen torch 1 of another person in step 71, the switching instruction transmission unit 95 generates the action instruction command 98 containing the switching instruction S1 and transmits the action instruction command 98 to the other surrounding pen torch 1 in step 72.

When the wireless communication unit 25 receives the information (second information, wireless communication packet) containing the light emission pattern M in step 73, the second functional unit 32 determines whether the received light emission pattern M is the immediately-operating light emission pattern M1 or the next light emission pattern M2 based on the information contained in the wireless communication packet in step 74. If it is the next light emission pattern M2, the second light emission pattern reception unit 37 saves the received light emission pattern M as the next light emission pattern M2 in the memory 50 in step 75. On the other hand, if the received light emission pattern M is the light emission pattern M for immediate operation, in step 76, the second switching means 35 controls the light emission unit 10 using the received light emission pattern M as the light emission pattern M1 during operation. For example, if the received light emission pattern M for immediate operation is an extinction pattern, the second switching unit 35 extinguishes the light emission unit 10.

The second functional unit 32 includes a function of receiving a command indicating other actions including or not including the light emission pattern M and interpreting the command. For example, a command can be received through the wireless communication unit 25, whereby the action mode of the pen torch 1 is switched between a mode in which the light emission state is switched by detecting an activity and a mode in which the activity is not detected and the light emission state is switched according to a wireless instruction, or switched between a mode in which the light emission state is switched by detecting an activity and a mode in which an operation is autonomously performed locally by the user without detecting an activity.

Fig. 5 shows a case where a plurality of pen torches 1 are lighted as in torch relay. The pen torch 1 has a size and a structure that is safe even when swung, for example, the entire length of which is 250mm or less, the light emitting portion 10 has a diameter of about 15mm, the device portion (handle portion) 20 has a diameter of about 25mm that is easy to hold, 4 battery cells 40 are mounted, and the substrate on which the CPU 30 and the memory 50 are mounted can be integrated into about 15mm × 40mm, which is enough to be accommodated in the handle portion 20.

As shown in fig. 5 (a), the pen torch 1a emits light in a light emission mode (electronic candle light emission mode) Mc in which light is emitted by flickering of an amber color to form a flame screen. When the other pen torch 1a approaches the own pen torch 1b and enters a communication range (for example, within a distance to the extent that it can be reached by a hand) of the near field communication unit 21 using visible light or infrared light as a medium, the own pen torch 1b receives a communication packet containing the light emission pattern Mc, and stores the received light emission pattern Mc in the memory 50 as the next light emission pattern M2.

When another pen torch 1a touches its own pen torch 1b as shown in fig. 5 (b), the first switching means 34 of its own pen torch 1b starts control of the light emitting unit 10 with the light emission pattern Mc received as it is as the light emission pattern M1 in operation. Thus, as shown in fig. 5 (c), the own pen torch 1b emits light in the electronic candle light emission mode Mc. At the same time, the first switching unit 34 outputs a communication packet including the light emission pattern Mc in operation to the surroundings through the short-range communication unit 21. Therefore, when the pen torch 1b of the user is brought close to and touched to the pen torch 1 of a different person, the pen torch is also lighted in the electronic candle lighting mode Mc.

When the pen torch 1 receives the light emission pattern (light emission ID) by the proximity communication, the pen torch 1 on the receiving side is in a standby state of emitting light, and the light emission is turned on when the touch is detected by the acceleration sensor 22. Then, the transmission of the light emission pattern also becomes on at this timing. Therefore, by using the pen type flashlights 1, it is possible to switch the respective pen type flashlights 1 by a common action with another user or an instruction from another user instead of switching the respective pen type flashlights 1 by itself, in this example, by touching the light emitting portions 10 of the respective pen type flashlights 1 to each other, and it is possible to cause the pen type flashlights 1 on the other side to emit light in the same display mode as the own pen type flashlights 1.

Fig. 6 shows different states of lighting a plurality of pen torches 1. When the pen torch 1a of another user approaches the pen torch 1b of the own user as shown in fig. 6 (a) and comes within the communication range of the near field communication unit 21, for example, a distance to the extent that the eyes (sight) can clearly recognize, the pen torch 1b of the own user receives the communication packet containing the light emission pattern Mc and stores it in the memory 50.

When another user waves the pen torch 1a toward the pen torch 1b of the other user as shown in fig. 6 (b), the motion detection unit 90 of the pen torch 1a detects the motion, and the switching instruction transmission unit 95 transmits a command 98 including a switching instruction S1 via the near field communication unit 21.

When the switching instruction receiving unit 96 of the own pen torch 1b receives the command 98 containing the switching instruction S1 as shown in fig. 6 (d), the switching instruction S1 is output, and the own pen torch 1b emits light in the same light emission pattern Mc as the pen torch 1a of the other user. At the same time, the first switching unit 34 outputs a communication packet including the light emission pattern Mc in operation to the surroundings through the short-range communication unit 21. Therefore, when the pen torch 1b is swung toward another pen torch 1 different from the pen torch, the pen torch 1 emits light in the same light emission pattern Mc.

When the own pen torch 1b is waved to receive light from the pen torch 1a of the other user as shown in fig. 6 (c), the activity detection unit 90 of the own pen torch 1b outputs a switching instruction S1. Thus, like fig. 6 (d), the own pen torch 1b emits light in the same light emission pattern Mc as the pen torch 1a of the other user.

Therefore, in the pen torch 1, by swinging the pen torch 1 toward the other side in a throwing manner, the pen torch 1 located at a near place or a certain distance can be lighted up in the same color or pattern, and the pen torch 1 located at a near place or a certain distance can be extinguished in the same color or pattern. Further, by holding the pen torch 1 and performing a movement such as receiving light, the pen torch 1 can be lit in the same color or pattern as the pen torch 1 located at a close distance or a predetermined distance.

Also, the pen torch 1 can transmit light when the motion of the pen torch 1b of the user is synchronized with the motion of the pen torch 1a of another user, for example, when the motion of throwing is synchronized with the motion of receiving. For example, the following control can be performed: the light emission mode is switched when the timing of receiving the command 98 containing the switching instruction S1 by the near field communication unit 21 coincides with the timing of outputting the switching instruction S1 by the activity of the own pen torch 1 within a prescribed time difference. Also, it is also possible to throw lights to each other in a game feeling by defining the kind of an activity or a performance to be synchronized.

In fig. 7, there is shown a system 85, which system 85 comprises a plurality of pen flashers 1 and a system control unit 80 for transmitting communication packets containing light emission patterns by wireless to control the plurality of pen flashers 1. First, an extinguishing mode is transmitted from the system control unit 80 to the plurality of pen torches 1 to extinguish the pen torch 1. In each pen torch 1, the second function unit 32 interprets the extinguishing mode as a light emitting mode for immediate execution, and the second switching unit 35 switches the operation of the light emitting section 10.

Next, the pen torch 1 which is previously lighted in the lighting mode Mc is brought close to and brought into contact with another pen torch 1. Alternatively, the pen torch 1 is swung toward the other pen torch 1. These actions (activities) are repeated among users holding the pen torch 1, whereby the pen torch 1 can be made to emit light successively in the same display manner. Therefore, by sensing the contact (touch) between the pencils to control the lighting opportunity, a performance like a torch delivery can be enjoyed among a large number of users. Further, the pen torch 1 of the counterpart can be lighted by throwing a fire from a position at a certain distance to transmit light, and thus, the light can be lighted successively like a magic wand to enjoy a large number of users.

As described above, the plurality of pen flashlights 1 can be turned off once and then turned on successively to enjoy the transmission of light of a fire or other colors, and the plurality of pen flashlights 1 being turned on can also be turned off successively. Further, it is also possible to approach and touch a plurality of pen flashlights 1 that are being lit in different light emission patterns or virtually throw light (inflammation) from each other, thereby unifying the light emission patterns to a specific one.

The pen torch 1 can also receive the light emission pattern M from the system control unit 80 at any time via the wireless communication unit 25 to control the light emission (color development, display) of the pen torch 1 in the light emission pattern M. Thus, it is possible to control the lighting of the plurality of pen flashlights 1 in synchronization or to cause the plurality of pen flashlights 1 to light in random colors and timings by transmitting a random lighting pattern M wirelessly.

Further, the system control unit 80 may transmit the next light emission pattern M to the plurality of pen flashlights 1, and touch the pen flashlights 1 with one another, tap the pen flashlights 1 with a hand, or swing the pen flashlights 1, thereby independently pressing the plurality of pen flashlights 1 in the next light emission pattern M at various timings to emit light. Therefore, various performances can be performed using the plurality of pen flashlights 1, and performances in which audiences and stages are integrated and performances in which audiences are integrated can be enjoyed at concerts and competitions.

In the above description, the pen torch 1 is described as an example, but the portable light-emitting device may be any device including a portion that emits light, and may be a portable terminal using a display portion such as a liquid crystal display panel as a light-emitting portion. The same performance as described above can be enjoyed by downloading or adding a program including the above functions to a mobile terminal such as a smartphone. Functions such as Bluetooth (registered trademark) or infrared communication provided in a smartphone can be used as the short-range communication of the present invention. In addition, the acceleration sensor possessed by the smartphone can be utilized to detect contact between the smartphones or to detect other activities. Therefore, it is possible to enjoy the above-described light game and other programs such as the torch relay using the smartphone.

The light emitting device including the light emitting section dedicated for illumination or light emission is not limited to the pen type torch, and may be a lamp having another shape such as a ball shape or a disk shape, a handle connected to the light emitting section, or may directly hold the light emitting section. The light emitting device may also be a wearable lamp such as a wristwatch or a terminal including a display function.

The above-described performance is an example of performance performed using the light-emitting device according to the present invention, and other activities can be associated with transmission and reception of light, so that various performances and games can be enjoyed using the light-emitting device according to the present invention.
