Description

Technical Field

[0001] The present disclosure relates to a light-emitting device and an operating method thereof.

Background Art

[0002] Generally, a light-emitting device (or lighting device) can be meant as a device that reflects, refracts, and transmits light from a light source to achieve the purpose of illumination. The light-emitting device can be classified into an indirect light-emitting device, a semi-indirect light-emitting device, a general diffusion light-emitting device, a semi-direct light-emitting device, a direct light-emitting device, etc. according to the light distribution.

[0003] With the development of technology, the light-emitting device is used in various applications. As an example, the light-emitting device can be used in producing a media facade that embodies a media function by installing the light-emitting device on the outer wall of a building or the like. As another example, the light-emitting device can be used as a portable cheering good in performance venues such as sports competitions and concerts where the environment is below a certain illuminance.

[0004] There is an increasing number of performances in which the light-emitting device emits light uniformly in a pre-agreed pattern and the performers and the audience interact with each other, and it has taken root as a culture. The performance is generally carried out multiple times in many regions in the form of a tour, and from the perspective of the audience (fan) who is fanatically fond of the performer, it is very common to repeatedly participate in the performer's performance many times. As if reflecting this, a neologism "orcon" meaning participating in all the performances of the performer is even used.

[0005] When participating in a performance with a light-emitting device, before the start of the performance, a process of mapping the light-emitting device and the seats of the audience every time is required, which is for uniformly emitting light from the light-emitting device in a central control manner.

[0006] However, even for audiences who participate in the same performance multiple times, for each performance in a different session, the lighting device and the seats have to be mapped before the start of each performance, which is time-consuming and inconvenient as the staff running the performance also become extremely busy.

[0035] Hereinafter, with reference to the attached drawings, the operating principle and embodiments of the present disclosure will be described.

[0036] FIG. 1 is a conceptual diagram showing an illumination effect production system 1000 according to the present disclosure.

[0037] Referring to FIG. 1, the illumination effect production system 1000 in a performance venue according to the present disclosure may include a server 10, a light emission control device 200, a master device 300, a transmitter 400, and a light emission device 100 which is a receiving device.

[0038] The server 10 may include a database (DB), and the light emission control device 200 may include a simulator 201 for expressing, conceiving, and designing a scenario. The illumination effect production system 1000 can produce various forms of light emission patterns for performance shows such as cheering in the auditorium of the performance venue by controlling the light emission state of the light emission device 100 using the light emission control device 200.

[0039] The server 10 can store a database (DB) that stores various data required for producing illumination effects. The database (DB) can be provided with various performance data by the light emission control device 200 in ways such as wired communication, wireless communication, and direct data provision. For example, the server 10 can provide performance data to the light emission control device 200 in a wired network manner such as a coaxial cable, a wired LAN (LAN; Local Area Network) (for example, Ethernet). For example, the server 10 can provide performance data to the light emission control device 200 in the form of packets on a mobile communication network constructed by a standard communication method of mobile communication. For example, the database (DB) stored in the server 10 can be physically transferred to the light emission control device 200 via a storage medium such as a removable disk.

[0040] The light emission control device 200 can execute a function of controlling the light emission device 100 for a performance production in a performance venue. For example, the light emission control device 200 can be one of electronic devices such as a mobile phone, a smart phone, a laptop computer, a digital broadcast terminal, a PDA (personal digital assistants), a PMP (portable multimedia player), a navigation device, a slate PC, a tablet PC, an ultrabook, a wearable device (for example, a smart watch, a smart glass, an HMD (head mounted display)), etc., and can include all electronic devices capable of installing and executing an application according to an exemplary embodiment, or can be configured in various forms including a part of the configuration of such an electronic device or being able to cooperate with it.

[0041] In an embodiment, the light emission control device 200 may be one of electronic devices such as MA Lighting grandMA2, grandMA3, ETC EOS, ETC ION, ETC GIO, Chroma Q Vista, High End HOG, High End Fullboar, Avolites Sapphire Avolites Tiger, Chamsys MagicQ, Obsidian control systems Onyx, Martin M6, Martin M1, Nicolaudie Sunlite, ESA, ESA2, Lumidesk, SunSuite, Arcolis, Daslight, LightRider, MADRIX, DJ LIGHT STUDIO, DISCO-DESIGNER VJ STUDIO, Stagecraft, Lightkey, etc., and / or one of PC software.

[0042] The light emission control device 200 may include a simulator 201 for producing a lighting effect. The simulator 201 may be an electronic device that implements a virtual simulation for embodying the lighting effect, or software driven by an electronic device, or a composite device in which software and an electronic device are combined. For example, a user can input an electronic signal corresponding to a scene to be produced into the simulator 201, and the simulator 201 can convert the input electronic signal to conform to the protocol of the light emission control device 200 so that it can be driven by the light emission control device 200 and provide it to the light emission control device 200.

[0043] Various scenarios may be stored in the simulator 201 in advance or input from a user. A scenario may be a design conceived to induce a lighting effect using the light emitting device 100 throughout the performance time. The performer of the performance can conceive a scenario and input it into the simulator 201 to conform to it. The scenario may be different for each scene of the performance or for each song of each performance, and thus can function as a design for producing a cheering effect corresponding to each scene of the performance.

[0044] In an embodiment, the light emission control device 200 may include appropriate software or computer programs that enable control of the light emitting device 100. For example, the light emission control device 200 may include DMX512, RDM, Art-Net, sACN, ETC-Net2, Pathport, Shownet, or KiNET, etc. as exemplary protocols for controlling the light emitting device 100. The light emission control device 200 can transmit data signals (e.g., light emission control signals) in an appropriate format such as DMX512, Art-Net, sACN, ETC-Net2, Pathport, Shownet, or KiNET. The light emission control device 200 generates a light emission control signal to control the light emitting device 100, and the light emission control signal is transmitted to the light emitting device 100 so that one or more light emitting devices 100 can emit light according to the light emission control signal. The light emission control signal may include information regarding the light emission state (e.g., light emission hue, brightness value, blinking speed, etc.).

[0045] In an embodiment, the light emission control device 200 may include a plurality of input / output ports. The light emission control device 200 may include input / output ports corresponding to or related to a specific data signal format or protocol. For example, the light emission control device 200 may include a first port dedicated to DMX512 and RDM data input / output, and a second port dedicated to Art-Net and sACN, ETC-Net2, Pathport, Shownet, KiNET data input / output. The DMX512, RDM, Art-Net, sACN, ETC-Net2, Pathport, Shownet, and KiNET protocols are widely known as control protocols for stage lighting equipment. According to the embodiment, the light emission control device 200 can plan for more flexible control of the light emitting device 100 using control protocols such as DMX512, RDM, Art-Net, sACN, ETC-Net2, Pathport, Shownet, and KiNET.

[0046] The master device 300 may be provided for efficient signal transmission in a performance venue. The master device 300 may include a database (DB). The master device 300 can receive a control signal from the light emission control device 200 and provide the information of the database (DB) it stores to the transmitter 400 including the control signal, or directly provide it to the light emission device 100. The master device 300 may be an electronic device such as a mobile phone, a smart phone, a laptop computer, a digital broadcast terminal, a PDA (personal digital assistants), a PMP (portable multimedia player), a navigation device, a slate PC, a tablet PC, an ultrabook, a wearable device (for example, a smart watch, a smart glass, an HMD (head mounted display)), etc., but is not limited thereto. The master device 300 does not necessarily have to be provided as a separate hardware device, and may be embodied by being combined as a part of the light emission control device 200 or as a part of the transmitter 400.

[0047] As part of a communication device, the transmitter 400 can execute functions such as amplifying or transmitting the light emission control signal received from the light emission control device 200 or the master device 300. For example, the transmitter 400 may be embodied by a communication device such as an antenna. The transmitter 400 can receive the light emission control signal from the light emission control device 200 or the master device 300 and transmit it to the light emission device 100. By the transmitter 400 receiving the light emission control signal for controlling the light emission of the light emission device 100 from the light emission control device 200 and transmitting the light emission control signal to the light emission device 100, the light emission device 100 can emit light corresponding to the light emission pattern included in the light emission control signal.

[0048] In an embodiment, the transmitter 400 can be a general term for a plurality of transmitters. For example, the transmitter 400 may include a first transmitter 401, a second transmitter 402, and the like. For example, a plurality of transmitters may be provided in a performance venue, but by providing a first transmitter 401 for a first area and a second transmitter 402 for a second area, etc., a wireless control signal can be efficiently transmitted to each seat.

[0049] In an embodiment, although the transmitter 400 is disclosed as a device separate from the light emission control device 200, the light emission control device 200 may include a communication module that plays the same role as the transmitter 400. Therefore, the light emission control device 200 can perform the same role as the transmitter 400 according to the embodiment, and the light emission device 100 can receive a light emission control signal from the light emission control device 200 and emit light.

[0050] The transmitter 400 of the present disclosure may have directivity. The performance planner may arrange the transmitter 400 at the stage of performance planning in consideration of the specifications of the transmitters used in the corresponding performance. Therefore, the light emission device 100 can receive a light emission control signal from a transmitter 400 having identification information corresponding to the identification information of the transmitter stored in advance in itself.

[0051] Also, the light emission control signal generated by the light emission control device 200 is received by the master device 300, and the master device 300 can convert the light emission control signal into a wireless control signal. The master device 300 transmits the converted wireless control signal to the transmitter 400, and the transmitter 400 can send it out to the light emission devices 100 in the performance venue using wireless communication (for example, RF communication, etc.). Here, the wireless control signal is a form for controlling the light emission device 100 in a wireless communication method, and may be generated by converting control data.

[0052] The light emission device 100 can execute a function of producing various forms of light emission patterns in real time by the light emission control device 200 or according to predetermined control information.

[0053] In an embodiment, the light-emitting device 100 may include a light-emitting element such as an LCD (Liquid Crystal Display) or an LED (Light Emitting Diode), and may be connected to the light-emitting element. The light-emitting device 100 is a device including any electronic device capable of wireless communication, and may be a small cheering good carried by a spectator in a performance venue such as a sports stadium or a concert. For example, the light-emitting device 100 may be a mobile phone, a wireless receiving device, a writing stick, a writing bar, a writing ball, a writing panel, and an instrument with a wirelessly controllable light source attached thereto. In the present disclosure, the light-emitting device 100 may also be referred to as a lighting device, a receiver, a controlled device, a slave, or a slave lighting device. Further, the light-emitting device 100 may include a wearable device that can be attached to and / or worn on a part of the body such as the wrist or chest.

[0054] In the present disclosure, the light-emitting device 100 can interpret and emit light based on the light-emitting control signal received from the transmitter 400 based on the identification information of the transmitter 400 stored in advance. Specifically, the light-emitting device 100 compares the identification information of the transmitter 400 stored in advance with the identification information of the transmitter included in the light-emitting control signal. As a result of the comparison, if the two are the same, the light-emitting device 100 can emit light corresponding to the light-emitting pattern included in the corresponding light-emitting control signal.

[0055] In an embodiment, the light-emitting device 100 may be a general term for a plurality of light-emitting devices. For example, the light-emitting device 100 may include a first light-emitting device 101, a second light-emitting device 102, and the like. For example, a plurality of light-emitting devices may be located in a performance venue. The first light-emitting device 101 located in the first area can receive a control signal provided from the first transmitter 401, and the second light-emitting device 102 located in the second area can receive a control signal provided from the second transmitter 402. Thus, even though a plurality of light-emitting devices are located in the performance venue, distributed processing of the control signal is possible.

[0056] The lighting effect production system 1000 according to an exemplary embodiment of the present disclosure can produce group cheering for the audience. For example, the group cheering may be wave cheering. In one embodiment, the master device 300 can broadcast a control signal for group cheering to the performance venue. The light emitting device 100 located in the performance venue can blink in response to the control signal. Or, the light emitting device 100 can emit light with a weak intensity in response to the control signal.

[0057] In an embodiment, the light emitting device 100 may include at least one sensor for sensing the movement of the audience. If the light emitting device 100 receives a control signal for group cheering, it can use at least one sensor to sense the movement of the light emitting device 100. For example, the movement of the light emitting device 100 is caused by the movement of the audience. For example, the audience can move the light emitting device 100 up and down or wave it in place to participate in the group cheering. The audience is not restricted in direction and can also repeat the operation of moving the light emitting device 100 at various angles and returning it to the original position.

[0058] In an embodiment, the light emitting device 100 can emit light of a specified hue based on the movement of the light emitting device 100. For example, if the light emitting device 100 senses that it is moving up and down and the speed of the light emitting device 100 is equal to or higher than the specified speed, the light emitting device 100 can emit light of the specified hue at the specified intensity. The hue and its intensity of the light emitted by the light emitting device 100 may be determined by the control signal or may be based on the data stored in the memory of the light emitting device 100.

[0059] In an embodiment, the light emitting device 100 can emit light in a specified pattern based on the movement of the light emitting device 100. For example, if the light emitting device 100 senses that it is moving up and down, it can blink for a specified period of time.

[0079] The memory 150 can store data and instruction words for the operation of the light emitting device 100. At least a part of such application programs may be downloaded from an external device (e.g., the server 10) via wireless communication. The application program is stored in the memory 150 and provided on the light emitting device 100, and can be driven to execute operations (or functions) by the processor 190 of the light emitting device 100.

[0080] The memory 150 should retain data even when the power supplied to the light emitting device 100 is cut off, and may be provided as a writable non-volatile memory that can reflect changes.

[0081] According to an embodiment, the memory 150 can store seat information of tickets held by the audience. The seat information of the tickets stored in the memory 150 may include at least one of the seat information displayed on the ticket (e.g., seat No. 1 in row A), the position information of the corresponding seat among the seats in the performance venue (e.g., the row information of the corresponding seat), the identification information of the corresponding seat (e.g., when generating the performance production data, the seat located at the leftmost and uppermost among 50,000 seats is "No. 1"), and user information.

[0082] According to an embodiment, the memory 150 can store seat information input from the outside and provided to the light emitting device 100, and the processor 190 can grasp the coordinates of the light emitting device 100 by extracting the seat information stored in the memory 150. However, it is not limited thereto, and the memory 150 can also store seat information directly obtained by the light emitting device 100.

[0083] According to an embodiment, the light emitting device 100 can provide seat information to the server 10. For example, the light emitting device 100 can directly provide a signal including seat information to the server 10 via the communication unit 110, provide it to the server 10 via the user's smart device (not shown), or provide it to the server 10 via the master device 300. The server 10 can centrally manage performance data by storing the seat information.

[0084] According to an embodiment, the data stored in the memory 150 may be input to the light emitting device 100 in the form of firmware at the production stage of the light emitting device 100, or may be input via an application installed on the terminal (e.g., smartphone, tablet, PC) of the audience who holds the light emitting device 100 before or after entering the performance venue.

[0085] In an embodiment, the user, who is the audience, can electrically connect the terminal held by the user to the light emitting device 100, download control-related information for the performance from an external server via the application installed on the terminal, and store it in the memory 150. The electrical connection may be made by short-range wireless communication or physical connection between the terminal and the light emitting device 100.

[0086] In an embodiment, the data stored in the memory 150 may be input during the process of ticket confirmation before entry. Specifically, the audience can perform a ticket confirmation step before entering the performance venue. In this case, the performance staff directly inputs the seat information included in the ticket into the light emitting device 100, or uses the OCR function of an information confirmation device (not shown) or the two-dimensional electronic code reader function represented by a barcode, QR code, etc. to receive the transmission of the seat information included in the ticket, and provides control-related information related to the position information corresponding to the seat information to the light emitting device 100, so that it can be stored in the memory 150.

[0087] In an embodiment, the performance data may be position information for each seat in the performance venue. Also, the information confirmation device can provide control-related information related to the position information to the light emitting device 100 through real-time communication between an external server (for example, 10 in FIG. 1) and the performance venue, or store in advance control-related information related to the position information at the stage of performance planning and provide it to the light emitting device 100 at the performance venue.

[0088] In an embodiment, the information confirmation device may include an electronic device such as a kiosk (not shown). In this case, the audience can directly perform the ticket confirmation step through the kiosk. The kiosk receives the transmission of the electronic code information included in the ticket (in other words, the information read through a barcode, QR code, RFID, NFC, etc.), and provides control-related information related to the position information corresponding to the electronic code information to the light emitting device 100, so that it can be stored in the memory 150. In this case, the kiosk can store in advance control-related information related to the position information through communication with an external server (FIG. 1, 10) or at the stage of performance planning.

[0089] According to an embodiment, the memory 150 can pre-store hue data. As described above, the hue data is pre-stored before the performance, such as being stored at the production stage of the light-emitting device 100, or being stored before or after entering the performance venue and before the start of the performance. By pre-storing the hue data in this way, the lighting effect can be smoothly produced during the performance. In one embodiment, the hue data may include at least one of the hue, pattern, and intensity of the light emitted by the light-emitting device 100 during group cheering.

[0090] According to an embodiment, the hue data may include RGB values prepared to emit light in a hue predetermined according to the expression range of the data. To represent all hues, the RGB values having three color channels must be indicated as 3 bytes (byte). However, in the scene to be produced at the performance venue, it may not be necessary to substantially represent all natural colors, and it is necessary to reduce the data transfer amount and processing amount. Therefore, the hue data may include a mapping table related to some hues expressed by the light-emitting device 100 according to the scenario.

[0091] In addition, a sensing unit may be further included. The sensing unit senses at least one of the device's own information, the surrounding environment information surrounding the device, and user information, and generates a corresponding sensing signal. The processor 190 can control the driving or operation of the device or execute data processing, functions, or operations related to the application program installed in the device based on such a sensing signal.

[0092] In an embodiment, the sensing unit may include at least one sensor. The sensing unit may include an acceleration sensor, an IMU (inertial measurement) sensor, a vibration sensor, a gyro sensor, a magnetic sensor, etc., but the present disclosure is not limited thereto.

[0093] In an embodiment, when the movement of the light-emitting device 100 satisfies specified conditions, the light-emitting device 100 can emit light of a specified hue and / or pattern. For example, when the speed at which the viewer moves the light-emitting device 100 is equal to or higher than a constant speed, the light-emitting device 100 can emit light of a specified hue for a certain period of time (e.g., 1 second). For example, when the acceleration of the light-emitting device 100 is detected, the light-emitting device 100 can emit light of a specified hue for a certain period of time (e.g., 1 second). For example, when the acceleration of the light-emitting device 100 has at least one peak value during a preset period of time (e.g., 1 second), the light-emitting device 100 can emit light of a specified hue for a certain period of time (e.g., 1 second). For example, when the viewer moves the light-emitting device 100 in a specified direction (e.g., the diagonally right direction), the light-emitting device 100 can emit light in a specified pattern (e.g., blinking) for a certain period of time (e.g., 1 second). After a certain period of time has elapsed, the light-emitting device 100 can blink.

[0094] The processor 190 is electrically connected to the memory and can control the overall operation of the light-emitting device 100, more specifically, the operations of the other components that make up the light-emitting device 100. Such a processor 190 can be implemented by a general-purpose processor, a dedicated processor, or an application processor. In an embodiment, the processor 190 can be implemented by an arithmetic processor (e.g., a CPU (Central Processing Unit), a GPU (Graphic Processing Unit), an AP (Application Processor), etc.) that includes a DSP (Digital Signal Processor), an MCU (Micro Controller Unit), or dedicated logic circuits (e.g., an FPGA (Field Programmable Gate Array), ASICs (Application Specific Integrated Circuits), etc.) that can convert analog signals into digital signals and perform high-speed processing, but is not limited thereto.

[0095] Functions related to artificial intelligence according to the present disclosure are executed by a processor and a memory. The processor is composed of one or more processors. At this time, the one or more processors may be a general-purpose processor such as a CPU, an AP, a DSP (Digital Signal Processor), a dedicated graphics processor such as a GPU or a VPU (Vision Processing Unit), or an artificial intelligence dedicated processor such as an NPU. The one or more processors control the input data to be processed according to a predefined operation rule or an artificial intelligence model stored in the memory. Or, when the one or more processors are artificial intelligence dedicated processors, the artificial intelligence dedicated processors may be designed with a hardware structure specialized for the processing of a specific artificial intelligence model.

[0096] At least one component may be added or deleted corresponding to the performance of the components shown in FIG. 3. Also, it will be easy for those having ordinary knowledge in the art to change the relative positions of the components corresponding to the performance or structure of the system.

[0097] On the other hand, each component shown in FIG. 3 means a component of software and / or hardware such as a Field Programmable Gate Array (FPGA) and an Application Specific Integrated Circuit (ASIC).

[0098] FIG. 4 exemplarily shows a state of a performance venue where a plurality of light emitting devices according to the present disclosure are arranged.

[0099] In FIG. 4, the lighting production of the performance venue may be realized by the system 1000 of FIG. 1. The performance venue is a physical space where a performance is produced, and may include a stage 600 and auditoriums 610, 620, 630. On the stage 600, a performance can be produced with various effects. In the auditoriums 610, 620, 630, seats are provided for the audience to watch the performance, and each seat can have unique coordinates. The auditoriums 610, 620, 630 can include at least one area according to the scale of the performance venue. For example, the auditoriums 610, 620, 630 include a first area 610, a second area 620, and a third area 630. The performance venue in FIG. 4 is exemplary, and the present disclosure is not limited thereto. For example, the performance venue may have a multi-layer structure. In this case, the areas of the auditorium may be divided into the first floor and the second floor.

[0100] In an embodiment, some of the light-emitting devices 100 of the performance venue may exist in a paired or unpaired state with the performance venue. For example, when the light-emitting device 100 is paired with the performance venue, the light-emitting device 100 may include seat information corresponding to the ticket held by the audience in the memory 150. For example, prior to the start of the performance, the audience can connect the light-emitting device 100 to the user terminal and input seat information (e.g., at least one of the seat position information displayed on the ticket, the identification information of the corresponding seat, and the user information) to the light-emitting device 100 via an application installed on the user terminal. The seat information can be obtained during the ticket verification process before entry, during the process where the user located in the auditorium inputs an application installed on the user terminal, or when the specific receiving device is within a certain distance of a relay device (Router) or beacon that is part of the short-range communication device using short-range communication, etc., but is not limited thereto.

[0101] In an embodiment, the light emitting device 100 can operate in at least one mode. For example, the light emitting device 100 can operate in a performance mode or a Bluetooth mode at a performance venue. The performance mode can be understood as a mode in which the light emitting device 100 receives a control signal broadcast by the master device 300 or the light emission control device 200 at the performance venue and produces a lighting effect in cooperation with the performance. The Bluetooth mode can be understood as a mode for the light emitting device 100 to wirelessly connect to a user terminal (e.g., a smartphone) held by a spectator.

[0102] In an embodiment, in order for the light emitting device 100 to produce a lighting effect by a control signal, the light emitting device 100 may be required to be paired with the performance venue. If the light emitting device 100 is not paired with the seats at the performance venue, the light emitting device 100 can emit arbitrary light by a user operation regardless of the performance in the performance mode. In this case, the master device 300 can broadcast a control signal instructing the light emitting device 100 not paired with the performance venue to maintain a blinking state in order to prevent the light emitting device 100 from emitting light not related to the performance.

[0103] In an embodiment, before or during a performance, the light emitting device 100 can be operated in the Bluetooth mode by a spectator's operation. In the Bluetooth mode, the light emitting device 100 may not be able to receive a control signal broadcast by the master device 300. Therefore, during a performance, all the light emitting devices 100 need to be switched to the performance mode.

[0104] In an embodiment, the light emitting device 100 may be set to automatically change to the performance mode when there is no Bluetooth connection for a specified time (e.g., 30 seconds or 1 minute) in the Bluetooth mode.

[0105] In an embodiment, when the lighting device 100 is paired with a seat, if there is no Bluetooth connection for a specified time (e.g., 30 seconds or 1 minute), it may be set to automatically change to the performance mode.

[0106] In an embodiment, when the audience enters the performance venue and turns on the lighting device 100, the lighting device 100 can receive a wireless signal (e.g., RF (radio frequency)) from the master device 300 in the performance venue. In this case, the lighting device 100 is automatically switched to the performance mode.

[0107] In an embodiment, group cheering can be performed in the performance venue according to the instructions of the performer. The group cheering may be wave cheering. The performer can broadcast a control signal by the master device 300 for the performance of group cheering. The broadcast control signal can be received via the lighting device 100 held by the audience watching the performance.

[0108] FIG. 5 is a sequence diagram showing an operation method of a lighting device that emits light based on mapping data for each performance according to the present disclosure. FIGS. 6 to 9 are drawings for specifically explaining a method of storing mapping data for each performance according to the present disclosure. In the part necessary for explaining FIG. 5, FIGS. 6 to 9 will be referred to together for explanation.

[0109] In step S710, the processor 190 can store the mapping data for the performance in the memory 150.

[0110] Specifically, the processor 190 can store in the memory 150 the mapping data for mapping the lighting device 100 and the seats in the performance venue in the performance (step S711).

[0111] Here, a performance may include one of each performance conducted a specific number of times, each performance repeatedly conducted during a specific period, a performance conducted on a specific date, and a performance conducted at a specific time.

[0112] The specific number of times may be one or more. The performances of the specific number of times may be performances with different sequences of the same performers, and may also be performances conducted at the same location. However, they may also be performances of different performers depending on the embodiments, and may be performances conducted at different locations. Each of the performances of the specific number of times can be stored in the memory 150 after being classified by performance identification information. The specific period may be a preset period of one day or more, and one or more performances may be conducted during the specific period. The processor 190 can store the mapping data of each performance in the memory 150 simultaneously for each performance, but can also store them in the memory 150 sequentially according to the storage order. Depending on the embodiment, they can also be stored in the order of the start of the performances.

[0113] In an embodiment, the mapping data may include identification information for each of the performances of the specific number of times, and may also include seat information. The seat information may include specific location information inside or outside the performance venue. The seat information may include floor information, area information, line information, group information, etc., but the present disclosure is not limited thereto.

[0114] In an embodiment, the mapping data may include group information (MD1) corresponding to the seats. For example, the mapping data may include group information including the seats (for example, one of 15 groups).

[0115] In an embodiment, the mapping data may include at least one of a light emission pattern, light emission intensity, light emission color, and light emission time for each scene (MD2). In this case, the processor 190 can receive a trigger signal (for example, a scene number) of the light emission control device 200 during the performance, and control the light emission unit 130 to emit light corresponding to the mapping data.

[0116] As described above, the mapping data can store at least one of the light emission pattern, light emission intensity, light emission color, light emission time, and group information corresponding to the seats for each scene in the memory 150.

[0117] Referring to FIG. 6, the terminal 700 is a device for mapping and storing seat information and identification information of the light emitting device 100 in a performance venue, and may be implemented by a kiosk, a tablet PC, a computer, a laptop, etc., but the embodiments are not limited thereto.

[0118] The terminal 700 can output performance information 750 to the display 740. The performance information 750 may include information on performers, performance date and time, location information, etc., but the embodiments are not limited thereto. The performance information 750 can be switched to a subsequent screen by a user operation (for example, a touch input).

[0119] The terminal 700 can provide a guide message 760 to map (pair) the seat information and the light emitting device 100.

[0120] The terminal 700 can provide a mapping service in various languages, and can provide various languages including Korean, English, Japanese, Spanish, Chinese, Indonesian, etc. The selected language (770, for example, Korean) can be highlighted and displayed.

[0121] Referring to FIG. 7, the terminal 700 can output an item corresponding to the light emitting device 100 to the display 740 and can output a guide message in order to pair with the light emitting device 100. Here, in the case of pairing, it may be a process for pairing the terminal 700 and the light emitting device 100 (for example, Bluetooth pairing).

[0122] For this purpose, the terminal 700 can output a guide message ("Press for 2 seconds simultaneously") for controlling the item 120A corresponding to the input unit of the light-emitting device 100. When a corresponding command (command to press the button for 2 seconds simultaneously) is input to the input unit according to the guide message, the light-emitting device 100 can emit light in blue as set in advance.

[0123] In order to check whether the light-emitting unit 130 of the light-emitting device 100 is blinking in blue, the terminal 700 can provide the item 130A corresponding to the light-emitting unit 130 as a guide image on the display 740.

[0124] Referring to FIG. 8, when the light-emitting device 100 is blinking in blue by the operation of the user, the terminal 700 can receive the input of seat information. The terminal 700 can receive the input of seat information for each performance by the operation of the user.

[0125] In an embodiment, the terminal 700 can also acquire (extract) the corresponding seat information from the performance ticket (offline or online).

[0126] Referring to FIG. 9, when receiving the input of seat information, the terminal 700 can receive the input of the identification number of the light-emitting device 100B. The terminal 700 can receive the input of the identification information of the light-emitting device 100B by the operation of the user.

[0127] In an embodiment, the terminal 700 can also automatically receive the identification information of the light-emitting device 100B directly from the paired light-emitting device 100B, and can receive the identification information of the light-emitting device 100B immediately after the pairing is performed.

[0128] In step S720 of FIG. 5, the processor 190 can control the light-emitting unit 130 to emit light corresponding to the mapping data according to the trigger signal received via the communication unit 110 in each of a specific number of performances.

[0129] Specifically, during a performance, the processor 190 receives, via the communication unit 110, group control signals corresponding to each scene from the light emission control device 200 (S721), and can control the light emission unit 130 to emit light corresponding to the group information (S723).

[0130] Even if the processor 190 does not receive group information via the communication unit 110, it can count the order of the group control signals for each scene (S723A), and recognize the group information based on the counted order (S723B).

[0131] In an embodiment, the processor 190 can receive at least one piece of information among a light emission pattern, light emission intensity, light emission color, and light emission time for each scene from the light emission control device (200 or master device 300) and emit light accordingly. In this case, the processor 190 can emit light without the characteristic information for light emission for each scene being stored in the memory 150, and can directly receive the information on the characteristics for each scene via a transmitter corresponding to the area (group) where the light emission device 100 is arranged, and thereby emit light. In this case, the characteristic information for light emission for each scene is not stored, which is efficient in managing the capacity of the memory 150.

[0132] Hereinafter, a scenario in which the processor 190 stores data will be specifically described.

[0133] When a trigger condition for deleting the mapping data stored in the memory 150 is satisfied, the processor 190 can delete the mapping data previously stored in the memory 150 based on a preset criterion.

[0134] The processor 190 can determine whether a trigger condition for deleting pre-stored mapping data according to the number of storage times or performance times is satisfied. Specifically, the processor 190 can determine that the trigger condition is satisfied when the number of storage times of the mapping data exceeds a preset reference storage number, or when the number of performance times of a specific performance exceeds the reference performance number.

[0135] Here, the processor 190 can uniformly determine the reference storage number or the reference performance number. According to the embodiment, it is also possible that the reference storage number or the reference performance number is determined according to the number of performances performed by the same artist in a specific region, and it is also possible that it is determined according to the capacity of the mapping data to be stored or the capacity of the memory. However, the present disclosure is not limited thereto.

[0136] In addition, after the mapping data is stored in the memory 150, the processor 190 can determine that the trigger condition is satisfied when the preset period is exceeded, or when the preset period is exceeded after the performance ends. Here, the preset period may be uniformly determined, or may be determined according to the performance periods of sequentially performed performances in several regions. However, the present disclosure is not limited thereto.

[0137] In addition, when the mapping data to be stored is not stored in the memory 150 according to the capacity of the memory 150, the processor 190 can determine that the trigger condition is satisfied.

[0138] When the above-described trigger condition is satisfied, the processor 190 can preferentially delete the mapping data corresponding to the ended performance. However, the embodiment is not limited thereto.

[0139] In addition, the processor 190 can confirm the user's intention to delete immediately before deleting the pre-stored mapping data. However, the embodiment is not limited thereto.

[0140] In an embodiment, the processor 190 can monitor whether the mapping data to be stored can be stored in the memory 150 according to the capacity of the memory 150. In an embodiment, the processor 190 can store the mapping data in a segmented manner, such as the space where the mapping data is stored and / or the space where the data related to the performance is stored.

[0141] In an embodiment, the processor 190 can delete the mapping data corresponding to the completed performances among the mapping data pre-stored in the memory 150 based on the capacity of the mapping data to be stored, and store the mapping data to be stored in the memory 150.

[0142] In this case, the processor 190 can delete the mapping data corresponding to the oldest performance or the performance with the largest capacity among the completed performances, but the present disclosure is not limited thereto.

[0143] In an embodiment, when the processor 190 transfers the ticket for a specific performance to another person, the processor 190 can delete the corresponding mapping data even if the performance has not ended, but the present disclosure is not limited thereto.

[0144] In an embodiment, when the capacity of the mapping data for each performance in a specific number of times and / or a specific period (which may include a specific date and / or a specific time) exceeds the storage capacity of the memory 150, the processor 190 can sequentially store the mapping data for each of the partial performances that can be stored in the memory 150 in the memory 150.

[0145] The processor 190 can sequentially store the mapping data for each of the remaining performances that have not been stored in the remaining area of the memory 150 excluding the area where the mapping data for each of the partial performances and the data related to each of the partial performances are stored, within the range where the memory 150 can store the data.

[0146] When at least a part of a specific number of performances stored in the memory 150 is in a non-participable state, the processor 190 can sequentially store, within the range where it is possible to store, mapping data for each of the remaining performances not stored in the area of the memory 150 corresponding to the performance in the non-participable state. Here, the non-participable state may include cases such as when a refund is made for the corresponding performance or when it is transferred, but the embodiments are not limited to this.

[0147] In an embodiment, when storing mapping data and related data (for example, including function information for causing the light-emitting device 100 to emit light according to the mapping data) for each of at least one performance among a specific number of times, a specific period, a specific date, and a specific time, the processor 190 can check whether the mapping data and related data for the performance whose period has already passed are stored in the memory 150. The processor 190 can monitor the capacities of the mapping data and related data classified by the identification information for each performance.

[0148] In an embodiment, when it is possible to store mapping data and related data for each of at least one performance among a specific number of times, a specific period, a specific date, and / or a specific time that are the input targets, the processor 190 can store them in the memory 150 by being classified by the identification information corresponding to each performance.

[0149] In an embodiment, when it is impossible to store mapping data and related data for each of at least one performance among a specific number of times, a specific period, a specific date, and / or a specific time that are the input targets, the processor 190 can delete the mapping data and related data for each of the performances whose periods have already passed.

[0150] At this time, the processor 190 can inquire the user who holds the light emitting device 100 whether to allow deletion of data (mapping data and / or related data) for each performance whose period has already elapsed. If the user consents, after deleting the corresponding data, the mapping data and / or related data for each performance that can be stored can be stored in the memory 150. If the processor 190 has difficulty storing the mapping data and / or related data for the performance to be input even after deleting the data whose period has already elapsed, it may not be necessary to delete the data whose period has already elapsed.

[0151] In an embodiment, when it is difficult to store any of the mapping data for each performance of at least one of a specific number of times, a specific period, a specific date, and / or a specific time that is the input target in the current situation, the processor 190 can store the mapping data and related data for the performance that arrives earlier in time in the memory 150, and can be stored in the memory 150 according to the user's selection.

[0152] On the other hand, the disclosed embodiment can be embodied in the form of a recording medium storing computer-executable instruction words. The instruction words may be stored in the form of program code, and when executed by a processor, can generate a program module and perform the operations of the disclosed embodiment. The recording medium can be embodied as a computer-readable recording medium.

[0153] The computer-readable recording medium includes all types of recording media storing instruction words readable by a computer. For example, there may be a ROM (Read Only Memory), a RAM (Random Access Memory), a magnetic tape, a magnetic disk, a flash memory, an optical data storage device, and the like.

[0154] The disclosed embodiments have been described with reference to the attached drawings as above. Those having ordinary knowledge in the technical field to which the present disclosure pertains should be able to understand that the present disclosure can be implemented in forms different from the disclosed embodiments without changing the technical idea and essential features of the present disclosure. The disclosed embodiments are exemplary and should not be construed in a limiting sense.
