Abstract

This disclosure relates to a light-emitting device that emits light suitable for an externally outputting sound source, and a light-emitting control device that controls the emission of light. The light-emitting control device includes an antenna, a communication unit, a sensing unit, and a processor electrically connected to the antenna, the communication unit, and the sensing unit.

Description

Technical Field

[0001] The present disclosure relates to a light-emitting device and a light-emitting control device. More specifically, the present disclosure relates to a light-emitting device and a light-emitting control device that perform light emission suitable for a sound source being output externally.

Background Art

[0002] Generally, a light-emitting device (or lighting device) can be meant to be 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 light distribution.

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

[0004] Conventional light-emitting devices have a problem in that it is difficult to provide a cheering effect corresponding to the sound source of an artist that is contacted in daily life rather than such a performance environment. For example, a user can enjoy a sound source through a general audio device, enjoy a sound source through a television broadcast or a radio broadcast, or enjoy a sound source through a sound device installed on the street. Therefore, in order to specifically solve the above problems, there is an actual situation where a light-emitting device that provides a cheering effect in a performance venue and a cheering effect for a sound source contacted in daily life in different modes has been devised.

[0005] Also, there is an actual situation where a master device has been devised that controls so that a light-emitting device can provide an effect corresponding to a sound source reproduced in a specific space without performing separate pairing.

Summary of the Invention

[0006] The embodiments disclosed herein are intended to receive and recognize sound sources being output in a performance venue or other environment, and to create a cheering effect by performing a light emission operation appropriate to the recognized sound source.

[0007] Furthermore, the embodiments disclosed herein are intended to receive sound sources containing control information and synchronization information in a performance venue or an environment other than a performance venue, and to produce cheering effects based on these.

[0008] The issues that this disclosure aims to address are not limited to those mentioned above, and other issues not mentioned should be clearly understood by an average engineer from the following description. [Means for solving the problem]

[0010] Furthermore, the light emission control device according to this disclosure for achieving the above-mentioned technical challenges includes an antenna, a communication unit, a sensing unit, and a processor electrically connected to the antenna, the communication unit, and the sensing unit. The processor receives sound sources output externally via the sensing unit, and if the light emission control device is equipped with a database storing at least one sound source and light emission control information mapped to the at least one sound source, it searches the database for light emission control information mapped to the same sound source as the received sound source. If the light emission control device is not equipped with the database, the processor generates light emission control information for instructing light emission in a specific hue and pattern based on the received sound source, and can transmit a light emission control signal corresponding to the retrieved or generated light emission control information via the antenna.

[0011] In addition, computer programs stored on computer-readable recording media for performing methods to embody this disclosure may be further provided.

[0030] Figure 1 is a conceptual diagram showing a lighting effect system according to an exemplary embodiment of the present disclosure.

[0031] Referring to Figure 1, a lighting effects system 10 in a performance hall according to one embodiment of the present disclosure may include a server 100, a light emission control device 200, a master device 300, a transmitter 400A, and a light emission device 500. In accordance with the present disclosure, the light emission control device 200 may include at least one sound source and a database (DB) storing light emission control information mapped to each of the at least one sound source. The light emission control device 200 may also include a simulator 201 for representing, conceptualizing, and designing scenarios.

[0032] On the other hand, the database (DB) may, depending on the circumstances, be provided in the light emission control device 200, or it may be provided in a separate server such as the server 100 or a cloud server, and then, in cooperation with the light emission control device 200, the light emission control device 200 may be configured to search the database provided in the server 100 or cloud server for at least one sound source and the light emission control information, making them available for use.

[0033] The lighting effects system 10 can create various types of lighting patterns for performance effects, such as cheering in the audience seats of a performance hall, by controlling the lighting state of the light-emitting device 500 using the light-emitting control device 200. In one embodiment, the light-emitting device 500 can operate in a first mode in the lighting effects system 10.

[0034] Server 100 can store a database (DB) that stores various data necessary for creating lighting effects. The database (DB) can provide various performance data to the light emission control device 200 by methods such as wired communication, wireless communication, and direct data provision. For example, Server 100 can provide performance data to the light emission control device 200 by wired network methods such as coaxial cable and wired LAN (Local Area Network) (e.g., Ethernet).

[0035] For example, the server 100 can provide performance data to the light emission control device 200 in packet form over a mobile communication network constructed using a standard mobile communication protocol. For example, a database (DB) stored in the server 100 can be physically transferred to the light emission control device 200 via a storage medium such as a portable disk.

[0036] The light emission control device 200 may have the function of controlling the light emission device 500 for performance effects in a performance venue. For example, the light emission control device 200 may include any electronic device that can install and run the application according to the exemplary embodiment, such as a mobile phone, smartphone, laptop computer, digital broadcasting terminal, PDA (personal digital assistant), PMP (portable multimedia player), navigation system, slate PC, tablet PC, ultrabook, wearable device (e.g., smart watch, smart glass, HMD (head mounted display)), or it may include a part of the configuration of such an electronic device, or it may be configured in various forms that can work in conjunction with it.

[0037] In exemplary embodiments, the light emission control device 200 may be one of the following: an electronic device 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 PC software. The light emission control device 200 may include a simulator 201 for creating lighting effects.

[0038] The simulator 201 may be an electronic device that implements virtual simulation for realizing lighting effects, software driven by the electronic device, or a composite device combining software and an electronic device. For example, a user can input an electronic signal to the simulator 201 corresponding to a scene to be actuated, 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.

[0039] The simulator 201 may store various predefined scenarios, or users may input them. A scenario may be a blueprint designed to induce lighting effects using the light-emitting device 500 throughout the entire performance time. The performance director can design a scenario and input it into the simulator 201 accordingly. The scenario may differ for each scene of the performance, or for each song in each performance, and can function as a blueprint for creating appropriate cheering effects for each scene of the performance.

[0040] In an exemplary embodiment, the light emission control device 200 may include appropriate software or computer programs that enable control of the light-emitting devices 500. For example, the light emission control device 200 may include DMX512, RDM, Art-Net, sACN, ETC-Net2, Pathport, Shownet, or KiNET as exemplary protocols for controlling the light-emitting devices 500. 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 light emission control signals to control the light-emitting devices 500, and the light emission control signals are transmitted to the light-emitting devices 500 so that one or more light-emitting devices can emit light according to the light emission control signals. The light emission control signals may include information about the light emission state (e.g., light emission hue, brightness value, flashing speed, etc.).

[0041] In an exemplary embodiment, the light emission control device 200 may have multiple input / output ports. The light emission control device 200 may have input / output ports that correspond to or relate to a specific data signal format or protocol. For example, the light emission control device 200 may have 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, and 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 installations. According to the exemplary embodiment, the light emission control device 200 can be designed to provide more flexible control over the light emission device 500 using control protocols such as DMX512, RDM, Art-Net, sACN, ETC-Net2, Pathport, Shownet, and KiNET.

[0042] In one embodiment, the light emission control device 200 may include a sound source recognition sensor (e.g., a microphone). The light emission control device 200 receives and recognizes a sound source 400 being output in or outside the performance venue via the sound source recognition sensor 220, generates light emission control information based on the recognized sound source 400, and transmits a light emission control signal corresponding to the light emission control information to a light emission device 500 inside the performance venue via the antenna 240. For example, the light emission control signal may be an RF (radio frequency) signal radiated wirelessly.

[0043] The light emission control device 200 may further include an antenna for emitting a light emission control signal. The light emission control device 200 can emit a light emission control signal via the antenna. The light emission device 500 can receive the light emission control signal and emit light in a specified hue or pattern.

[0044] The light emission control device 200 may further include, in accordance with this disclosure, at least one sound source and a database storing light emission control information mapped to each of the at least one sound source. The light emission control device 200 recognizes the sound source 400, and if the sound source 400 is the same as a sound source stored in the database, it can retrieve the light emission control information mapped to the stored sound source information and radiate a light emission control signal corresponding to the retrieved light emission control information via the antenna 240.

[0045] In other words, if the light emission control device 200 is provided with the database, it searches the database for light emission control information mapped to the same sound source as the sound source 400 and transmits it to the light emission device 500. If the database is not provided, it generates light emission control information for instructing light emission in a specific hue and pattern based on the sound source 400 and transmits it to the light emission device 500. A detailed explanation of this will be given later.

[0046] The master device 300 may be provided for efficient signal transmission in the performance venue. The master device 300 may include a database (DB). The database of the master device 300 can store at least one sound source and light emission control information mapped to each of the at least one sound source. In this case, the light emission control device 200 may be configured to work in conjunction with the database of the master device 300 to search for and make available the at least one sound source and the light emission control information within the database of the master device 300.

[0047] The master device 300 receives control signals from the light emission control device 200 and can provide the control signals, including information from its stored database (DB), to the transmitter 400A or directly to the light emission device 500. The master device 300 may be, but is not limited to, an electronic device such as a mobile phone, smartphone, laptop computer, digital broadcasting terminal, PDA (personal digital assistant), PMP (portable multimedia player), navigation system, slate PC, tablet PC, ultrabook, or wearable device (e.g., smartwatch, smart glass, HMD (head mounted display)). The master device 300 does not necessarily need to be provided as a separate hardware device, but may be implemented as part of the light emission control device 200 or as part of the transmitter 400A.

[0048] As part of the communication device, the transmitter 400A can perform the function of amplifying and transmitting light emission control signals received from the light emission control device 200 or the master device 300. For example, the transmitter 400A may be embodied in a communication device such as an antenna. The transmitter 400A can transmit light emission control signals received from the light emission control device 200 or from the master device 300 to the light emission device 500. By receiving a light emission control signal from the light emission control device 200 to control the light emission of the light emission device 500 and transmitting the light emission control signal to the light emission device 500, the light emission device 500 can emit light corresponding to the light emission hue and light emission pattern included in the light emission control signal.

[0049] In an exemplary embodiment, transmitter 400A may be a common name for multiple transmitters. For example, transmitter 400A may include a first transmitter 401A, a second transmitter 402A, and so on. For example, a performance hall may have multiple transmitters, but by providing a first transmitter 401A for a first area and a second transmitter 402A for a second area, wireless control signals can be efficiently transmitted to each seat.

[0050] In the exemplary embodiment, the transmitter 400A is disclosed as a separate device from the light emission control device 200, but the light emission control device 200 may include a communication module that performs the same function as the transmitter 400A. Therefore, the light emission control device 200 can perform the same function as the transmitter 400A according to the embodiment, and the light emission device 500 can receive a light emission control signal from the light emission control device 200 and emit light.

[0051] The transmitter 400A of this disclosure may have directivity. The organizer of a performance may arrange the transmitter 400A at the performance planning stage, taking into consideration the specifications of the transmitter to be used in the performance. Therefore, the light-emitting device 500 can receive light-emitting control signals from the transmitter 400A which has identification information corresponding to the identification information of the transmitter that is pre-stored within it.

[0052] Furthermore, the light emission control signal generated from the light emission control device 200 is received by the master device 300, which 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 400A, which can then send it to the light emission devices 500 in the performance venue using wireless communication (e.g., RF communication). Here, the wireless control signal is in a form for controlling the light emission devices 500 by wireless communication, and may be generated by converting control data.

[0053] The light-emitting device 500 can have the function of producing various forms of light-emitting patterns in real time or according to predetermined control information, controlled by the light-emitting control device 200.

[0054] In exemplary embodiments, the light-emitting device 500 may include or be connected to light-emitting elements such as an LCD (Liquid Crystal Display) or an LED (Light Emitting Diode). The light-emitting device 500 is a device including any electronic device capable of wireless communication, and may be a small cheering item carried by spectators at performance venues such as sports stadiums or concerts. For example, the light-emitting device 500 may be a mobile phone, a wireless light-emitting device 500, a lighting stick, a lighting bar, a lighting ball, a lighting panel, or an object to which a wirelessly controllable light source is attached. In this disclosure, the light-emitting device 500 may also be referred to as a lighting device, a receiver, a controlled device, a slave, or a slave lighting device. The light-emitting device 500 may also include a wearable device that can be attached to and / or worn on a part of the body such as a wrist or chest.

[0055] In this disclosure, the light-emitting device 500 can interpret a light-emitting control signal received from the transmitter 400A based on pre-stored identification information of the transmitter 400A and emit light. Specifically, the light-emitting device 500 compares the pre-stored identification information of the transmitter 400A with the identification information of the transmitter included in the light-emitting control signal, and if the comparison shows that the two are the same, it can emit light in a manner corresponding to the light-emitting pattern included in the light-emitting control signal.

[0056] In an exemplary embodiment, the light-emitting device 500 may be a general term for multiple light-emitting devices. For example, the light-emitting device 500 may include a first light-emitting device 501 and a second light-emitting device 502. For example, multiple light-emitting devices may be located in the performance hall, and the first light-emitting device 501 located in the first area may receive control signals from the first transmitter 401A, and the second light-emitting device 502 located in the second area may receive control signals from the second transmitter 402A. This makes it possible to distribute the processing of control signals even though multiple light-emitting devices are located in the performance hall.

[0057] A lighting effects system 10 according to an exemplary embodiment of the present disclosure can create a spectacle of group cheering by an audience. For example, the group cheering may be a wave cheer. In one embodiment, a master device 300 can broadcast a light-emitting control signal for group cheering to the performance venue. A light-emitting device 500 located in the performance venue can flash in response to the light-emitting control signal. Alternatively, the light-emitting device 500 can emit light at a low intensity in response to the light-emitting control signal.

[0065] The processor 230 can control the overall operation of the light emission control device 200, and more specifically, the operation of other components comprising the light emission control device 200. Such a processor 230 can be embodied as a general-purpose processor, a dedicated processor, or an application processor.

[0071] According to exemplary embodiments of the present disclosure, the light control device 200 can broadcast a light control signal instructing group cheering (e.g., a wave). The light control signal for group cheering can be generated by the performer. In one embodiment, the light control signal can control a light-emitting device 500 located in the performance venue to flash and to sense the movement of the light-emitting device 500 using at least one sensor. In one embodiment, the light control signal may include light control information for at least one of the light color, pattern, and intensity of the light-emitting device 500 during group cheering. The description of the light control signal is exemplary and the embodiments of the present disclosure are not limited thereto.

[0072] In one embodiment, the processor 230 of the light emission control device 200 can use the sound source recognition sensor 220 to receive and recognize a sound source 400 that is output through a speaker placed in a specific space (for example, inside or outside a performance venue). For example, the sound source recognition sensor 220 can recognize the pitch and / or volume of the sound source 400.

[0073] In one embodiment, the processor 230 generates light emission control information based on the sound source 400 recognized by the sound source recognition sensor 220, and transmits a light emission control signal corresponding to the light emission control information to a light emission device 500 in the performance hall via the antenna 240. The light emission control signal can be radiated into a specific space via the antenna 240 in the form of an RF signal. The light emission device 500 receives the light emission control signal and can perform a light emission operation according to at least one of the light emission hue, light emission pattern, and light emission intensity indicated in the light emission control signal.

[0074] Furthermore, if the recognized sound source 400 is the same as a sound source stored in the database 255, the processor 230 can search for light emission control information mapped to the stored sound source information and emit a light emission control signal corresponding to the retrieved light emission control information via the antenna 240.

[0075] In other words, if the database is provided, the processor 230 searches the database for light emission control information mapped to the same sound source as the sound source 400 and transmits it to the light emission device 500. If the database is not provided, the processor 230 generates light emission control information for instructing light emission in a specific hue and pattern based on the sound source 400 and transmits it to the light emission device 500.

[0076] Furthermore, when generating the light emission control information, the processor 230 can identify at least one of the volume and pitch of the sound source 400, and generate light emission control information that instructs at least one of different light emission hues, light emission patterns, and light emission intensities based on the identified volume and pitch of the sound source 400. For example, the processor 230 can generate light emission control information that instructs the sound source 400 to emit light randomly based on at least one of the volume and pitch of the sound source 400. In addition, the light emission control information can be set so that the proportion of random emission differs depending on the user's selection.

[0077] Furthermore, when generating the light emission control information, the processor 230 can further recognize and identify at least one of the genre, type, or atmosphere of the sound source 400 via the sound source recognition sensor 220, and, according to the user's selection, generate light emission control information that instructs at least one of different light emission hues, light emission patterns, and light emission intensities based on at least one of the genre, type, or atmosphere of the sound source 400. For example, the processor 230 can further recognize at least one of the genre, type, or atmosphere of the sound source 400 based on at least one of the volume and pitch of the sound source 400 via the sound source recognition sensor 220.

[0078] Furthermore, the processor 230 can generate light emission control information that instructs the sound source 400 to emit light randomly based on at least one of its volume and pitch. The light emission control information can be set to have different random emission rates depending on the user's selection.

[0079] Furthermore, the processor 230 is connected to the lighting system (not shown) of the performance venue via the communication unit 210, or is electrically connected to the lighting system, and receives and provides lighting information used in the performance venue from the lighting system, and can search the database 255 or modify the generated light emission control information based on the provided lighting information.

[0080] In other words, different types of lighting are used in each performance venue according to the purpose, type, and character of the performance, and as a result, when the light-emitting device 500 performs a light-emitting operation for the performance, it will either adapt to the various lighting in the performance venue or perform a light-emitting operation that harmonizes with the various lighting.

[0081] Therefore, in this disclosure, the primary step is to search for or generate light emission control information that is suitable for the sound source, and the secondary step is to correct the searched or generated light emission control signal again so that the light emission operation (operation for at least one of the light emission hue, light emission pattern, and light emission intensity) is suitable for, compatible with, or in harmony with the lighting in the performance venue.

[0082] As an example, a light emission operation that is suitable, appropriate, or harmonious with the lighting in the performance venue means a light emission operation in which at least one of the emission hue, emission pattern, and emission intensity is changed so as to be suitable, appropriate, or harmonious with the hue, flashing pattern, and brightness of the lighting.

[0083] Furthermore, the processor 230 can recognize via the sound source recognition sensor 220 that the output of the sound source 400 has been interrupted and that a specific person in the performance hall (for example, a singer or presenter) is speaking. In this case, the processor 230 can generate light emission control information that controls the light emission device 500 to either emit light in a single color or turn off while the specific person (singer or presenter) is speaking, so that the audience can concentrate on what the specific person is saying.

[0084] Depending on the performance of the components shown in Figure 2, at least one component may be added or removed. Furthermore, it will be readily apparent to a person with ordinary skill in the art that the relative positions of the components can be changed in accordance with the performance or structure of the system.

[0085] On the other hand, each component shown in Figure 2 represents a software and / or Field Programmable Gate Array (FPGA) and hardware components such as Application Specific Integrated Circuits (ASICs).

The light-emitting device 500 can extract light emission control information contained in the sound source and emit light based on at least one of the light emission hue, light emission pattern, and light emission intensity indicated by the extracted light emission control information.

[0091] In one embodiment, the control information 410 can control the light-emitting device 500 to emit light based on at least one of a specified light hue, light pattern, and light intensity. For example, the control information 410 may include information about the light emission state (e.g., light hue, brightness value, flashing speed, vibration pattern, etc.). The control information 410 may include a time code corresponding to the playback time of the sound source. The time code can be linked with the information about the light emission state to indicate a lighting effect (or light emission state) to be produced at a specific playback time of the sound source.

[0092] In one embodiment, the sound source 400 may include at least one synchronization information 420. The at least one synchronization information 420 may include sound source information 430, pilot information for synchronizing the lighting effects produced by the light-emitting device 500, and fitting information. For example, the pilot information may be information for initiating synchronization. For example, the fitting information may be information for maintaining the synchronization latency below a specified time (e.g., 1 ms).

[0093] In one embodiment, the sound source information 430 may be acoustic information based on a musical scale. The user can enjoy the cheering effect of the light-emitting device 500 along with the sound source information 430.

[0094] In one embodiment, the control information 410 and the synchronization information 420 can be output by the electronic device 350 in a different frequency band than the sound source information 430. For example, the control information 410 and the synchronization information 420 can be output via an audible frequency band or an inaudible frequency band. For example, the sound source information 430 can be output via an audible frequency band.

[0095] Figure 4b shows the time-domain structure of a sound source 400 according to one embodiment of the present disclosure.

[0096] In one embodiment, the electronic device 350 can reproduce sound source information 430 contained in the sound source 400 via an acoustic output unit (e.g., a speaker). The electronic device 400 can output control information 410 and / or at least one synchronization information 420 via the acoustic output unit before or during the reproduction of the sound source information 430.

[0097] In one embodiment, the light-emitting device 500 can receive sound from a sound source 400 via a sensing unit (e.g., a microphone) 480. The light-emitting device 500 can convert the sound source 400 into the frequency domain and separate and extract control information 410 and / or at least one synchronization information 420 from the sound source information 430 in the frequency domain.

[0098] In one embodiment, the electronic device 350 can output control information 410 and first synchronization information 422 before playback of sound source information 430. The control information 410 and first synchronization information 422 can be output via the audible frequency band or the inaudible frequency band.

[0099] In one embodiment, when the electronic device 350 outputs control information 410 and first synchronization information 422 in the audible frequency band, the electronic device 350 can output control information 410 and first synchronization information 422 having a specified frequency pattern before reproducing sound source information 430. The light-emitting device 500 can identify the control information 410 and first synchronization information 422 via a sensing unit (e.g., a microphone) 580.

[0100] In one embodiment, when the electronic device 350 outputs control information 410 and first synchronization information 422 in the inaudible frequency band, the light-emitting device 500 can convert the sound source 400 into the frequency domain. The light-emitting device 500 can identify the control information 410 and first synchronization information 422 in the frequency domain. In this case, the first synchronization information 422 can be understood as pilot information.

[0101] In one embodiment, the electronic device 350 can output second synchronization information 424 during playback of the sound source 400. The electronic device 350 can output the second synchronization information 424 via an inaudible frequency band. The light-emitting device 500 can convert the received sound source 400 into the frequency domain and separate and extract the second synchronization information 424 from the sound source information 430. At that time, the second synchronization information 424 may be understood as fitting information.

[0102] On the other hand, the light-emitting device 500 may have a memory 550 that contains the same database as the database 255 which stores at least one sound source of the light-emitting control device 200 described above, and light-emitting control information mapped to the at least one sound source. In this case, the light-emitting device 500 may search the database for the same sound source as the sound source 400, similar to the light-emitting control information search operation of the light-emitting control device 200, and perform a light-emitting operation based on at least one of the light-emitting hue, light-emitting pattern, and light-emitting intensity indicated by the light-emitting control information mapped to the searched sound source.

[0103] Figure 5 is a block diagram showing a light-emitting device 500 according to an exemplary embodiment of the present disclosure. Descriptions that overlap with those in Figures 1 and 2 are omitted.

[0104] The light-emitting device 500 may include a communication unit 510, a processor 530, a memory 550, a light-emitting unit 570, and a sensor unit 580.

[0106] According to an exemplary embodiment, the communication unit 510 can support a common protocol for communicating with the communication unit 210 in Figure 2. For example, the communication unit 510 can transmit and receive wireless signals to and from at least one of a base station, an external terminal, or an external server on a mobile communication network constructed using GSM, CDMA, CDMA2000, EV-DO, WCDMA, HSDPA, HSUPA, LTE, LTE-A, etc., or communicate with the communication unit 210 using at least one of the following technologies: WLAN, Wi-Fi, Wi-Fi Direct, DLNA, WiBro, WiMAX, Bluetooth (registered trademark), RFID, Infrared Data Association (IrDA), UWB (Ultra Wideband), ZigBee, NFC (Near Field Communication), Wireless USB (Wireless Universal Serial Bus), TTL (Transistor-Transistor Logic), USB, IEEE1394, Ethernet, MIDI (Musical Instrument Digital Interface), RS232, RS422, RS485, Optical Communication, or Coaxial Cable Communication.

[0107] The processor 530 can control the overall operation of the light-emitting device 500, and more specifically, the operation of other components that make up the light-emitting device 500. Such a processor 530 can be embodied as a general-purpose processor, a dedicated processor, or an application processor. In exemplary embodiments, the processor 530 can be, but is not limited to, a DSP (Digital Signal Processor) or MCU (Micro Controller Unit) capable of converting analog signals to digital for high-speed processing, or an arithmetic processor (e.g., CPU (Central Processing Unit), GPU (Graphic Processing Unit), AP (Application Processor)) that includes dedicated logic circuits (e.g., FPGA (Field Programmable Gate Array), ASICs (Application Specific Integrated Circuits)) that support the calculations required in the light-emitting device 500.

[0108] In one embodiment, the processor 530 may include a first mode control unit 532 and a second mode control unit 534. The first mode control unit 532 can process light emission control signals received by the light emission control device 200. The second mode control unit 534 can process sound sources 400 received by the lighting effect system 20. The second mode control unit 534 can also extract control information 410 and synchronization information 420 from the sound source 400. For example, the second mode control unit 534 can extract control information 410 and synchronization information 420 in the frequency domain based on a Fast Fourier Transform (FFT) algorithm.

[0109] The memory 550 may be a local storage medium that supports various functions of the light emission control device 200. The memory 550 can store data and instruction words for the operation of the light emission device 500. At least some of such application programs may be downloaded from an external device (e.g., server 100) via wireless communication. The application programs can be stored in the memory 550, installed on the light emission device 500, and driven to operate (or function) by the processor 530 of the light emission device 500.

[0110] The memory 550 must retain data even when the power supply to the light-emitting device 500 is cut off, and may be provided as a writable non-volatile memory so that changes can be reflected. For example, the memory 550 can be implemented as a non-volatile memory such as flash memory, magnetic RAM (MRAM), spin-transfer torque MRAM, conductive bridging RAM (CBRAM), ferroelectric RAM (FeRAM), phase-change RAM (PRAM), and resisive RAM (ReRAM). However, the embodiments described herein are not limited to these, and for example, the memory 550 may be implemented as a dynamic random access memory (DRAM) such as DDR SDRAM (Double Data Rate Synchronous Dynamic Random Access Memory), LPDDR (Low Power Double Data Rate) SDRAM, GDDR (Graphics Double Data Rate) SDRAM, RDRAM (Rambus Dynamic Random Access Memory), DDR2 SDRAM, DDR3 SDRAM, or DDR4 SDRAM.

[0111] According to exemplary embodiments of this disclosure, the memory 550 can store seat information of a ticket held by a spectator. The seat information of a ticket stored in the memory 550 may include at least one of the following: seat information displayed on the ticket (e.g., seat A1), location information of the seat in the performance venue (e.g., location information of the seat), identification information of the seat (e.g., when generating performance production data, the seat located at the top left of 50,000 seats is labeled "1"), and user information.

[0112] According to an exemplary embodiment of the present disclosure, the memory 550 can store seat information that is input from an external source and provided to the light-emitting device 500, and the processor 530 can determine the coordinates of the light-emitting device 500 by retrieving the seat information stored in the memory 550. However, the memory 550 can also store seat information that is directly acquired by the light-emitting device 500.

[0113] According to an exemplary embodiment of the present disclosure, the light-emitting device 500 can provide seat information to the server 100. For example, the light-emitting device 500 can provide a signal containing seat information directly to the server 100 via the communication unit 510, or to the server 100 via a user's smart device (not shown), or to the server 100 via a master device 300. By storing the seat information, the server 100 can centrally manage performance data.

[0114] According to exemplary embodiments of this disclosure, the data stored in the memory 550 may be input to the light-emitting device 500 in the form of firmware during the production stage of the light-emitting device 500, or it may be input via an application installed on a terminal (e.g., smartphone, tablet, PC) of an audience member who is carrying the light-emitting device 500 before or after entering the performance venue.

[0115] In an exemplary embodiment, a user, who is a member of the audience, can electrically connect their own terminal to a light-emitting device and download control-related information for performance production from an external server via an application installed on the terminal, and store it in memory 550. The electrical connection can be made between the terminal and the light-emitting device 500 by short-range wireless communication or a physical connection.

[0116] In an exemplary embodiment, the data stored in memory 550 may be entered during the ticket verification process before entry. Specifically, spectators can do this at the stage of verifying their performance tickets before entering the performance venue. In this case, the performance staff can either manually input the seat information contained in the ticket directly into the light-emitting device 500, or receive the seat information contained in the ticket via an information verification device (not shown) using an OCR function or a two-dimensional electronic code reader function represented by a barcode, QR code, etc., and provide the light-emitting device 500 with control-related information related to the seat information and corresponding location information, which can then be stored in memory 550.

[0117] In an exemplary embodiment, the performance data may be location information for each seat in the performance venue. The information verification device can provide the location information and related control information to the light-emitting device 500 via real-time communication with an external server (e.g., 100 in Figure 1) at the performance venue, or it can pre-store the location information and related control information at the performance planning stage and provide it to the light-emitting device 500 at the performance venue.

[0118] In an exemplary embodiment, the information verification device may include an electronic device such as a kiosk (not shown). In this case, the audience can directly verify their performance tickets via the kiosk. The kiosk receives electronic code information contained in the ticket (in other words, information read via a barcode, QR code, RFID, NFC, etc.) and provides the light-emitting device 500 with location information and associated control-related information corresponding to the electronic code information, which can then be stored in the memory 550. In this case, the kiosk can store location information and associated control-related information in advance via communication with an external server (Figure 1, 100) or at the performance planning stage.

[0119] According to exemplary embodiments of this disclosure, the memory 550 can pre-store hue data. As described above, the hue data can be stored in advance of the performance, such as during the production stage of the light-emitting device 500, or before entering the performance venue or before the start of the performance after entering, thereby enabling smooth lighting effects during the performance. In one embodiment, the hue data may include at least one of the hue, pattern, and intensity of the light-emitting device 500 to emit during group cheering.

[0120] According to exemplary embodiments of this disclosure, the hue data may include RGB values ​​configured to emit light in predetermined hues depending on the data representation range. To represent all hues, an RGB value with three color channels needs to be specified as three bytes. However, in a scene to be performed in a performance venue, it may not be necessary to represent all full natural colors, and the amount of data transmitted and processed needs to be reduced. Therefore, the hue data may include a mapping table relating to some of the hues that the light-emitting device 500 will display depending on the scenario.

[0121] According to an exemplary embodiment of the present disclosure, the memory 550 may include the same database as the database 255 which stores at least one sound source of the aforementioned light emission control device 200 and light emission control information mapped to the at least one sound source.

[0122] The light-emitting unit 570 can include one or more light source elements, such as light-emitting diodes (LEDs). Furthermore, the light-emitting unit 570 can output light of various hues based on RGB color information using the light source elements.

[0123] The sensing unit 580 senses at least one of the following: internal information of the device, information about the surrounding environment of the device, and user information, and generates a corresponding sensing signal. Based on such sensing signals, the control unit can control the driving or operation of the device, or perform data processing, functions, or operations related to the application program installed on the device. The sensing unit described above may include at least one of the following: a sound source recognition sensor (microphone) that receives and recognizes an externally output sound source; a proximity sensor; an illumination sensor; a touch sensor; an acceleration sensor; a magnetic sensor; a gravity sensor (G-sensor); a gyroscope sensor; a motion sensor; an RGB sensor; an infrared sensor (IR sensor); a fingerprint recognition sensor; an ultrasonic sensor; an optical sensor (e.g., a camera); an environmental sensor (e.g., at least one of a barometer, hygrometer, thermometer, radiation detection sensor, heat detection sensor, or gas detection sensor); or a chemical sensor (e.g., a healthcare sensor, a biorecognition sensor, etc.). On the other hand, this device can combine and utilize information sensed by at least two of these sensors.

[0124] In one embodiment, the light-emitting device 500 can operate in either the first mode or the second mode.

[0125] In one embodiment, the light-emitting device 500 can provide the effects of the lighting effect system 10 in the first mode. The operation of the light-emitting device 500 in the first mode can be controlled by the first mode control unit 532.

[0126] In the first mode, the processor 530 can receive a light emission control signal via the communication unit 510 and emit light based on the light emission control signal via the light emission unit 570. In one embodiment, the light emission device 500 can provide a lighting effect system 20 in the second mode. The operation of the light emission device 500 in the second mode can be controlled by the second mode control unit 534.

[0127] The light-emitting device 500 can perform the operations of the 2-1 mode and the 2-2 mode in the second mode. That is, the second mode is a light-emitting operation related to sound source reception, and the 2-1 mode and the 2-2 mode will be described separately below.

[0128] First, in the second-first mode, the processor 530 can control the second mode control unit 532 to receive and recognize the sound source 400 via the sensing unit 580, search the database for a sound source identical to the recognized sound source 400, and perform a light emission operation based on at least one of the light emission hue, light emission pattern, and light emission intensity indicated by the light emission control information mapped to the searched sound source.

[0129] Next, in the second-second mode, the processor 530 controls the second mode control unit 532 to receive and recognize the sound source 400 via the sensing unit 580, extracts control information 410 and synchronization information 420 from the recognized sound source 430, and controls the light-emitting unit 570 to perform a light-emitting operation based on at least one of the light-emitting hue, light-emitting pattern, and light-emitting intensity indicated by the extracted control information 410, thereby providing a lighting effect corresponding to the sound source 400. Furthermore, the processor 530 can synchronize the lighting effect with the playback timing of the sound source information 430 based on the control information 410.

[0130] In one embodiment, the light-emitting device 500 can operate in a second mode instead of a first mode in a space with specific seats (e.g., a performance hall, theater, cafe, or restaurant). In this case, the processor 530 can produce lighting effects based on seat information already stored in the memory 550. Specifically, the processor 530 can emit light with a specified hue and pattern based on the sound source and seat information emitted in the space with specific seats. In this case, if multiple light-emitting devices exist in the space with specific seats, the multiple light-emitting devices can use the seat information to provide a group cheering effect.

[0131] At least one component may be added or removed depending on the performance of the components shown in Figure 5. Furthermore, it will be readily apparent to anyone with ordinary skill in the art that the relative positions of the components can be changed in accordance with the system's performance or structure.

[0132] On the other hand, each component shown in Figure 5 represents a software and / or Field Programmable Gate Array (FPGA) and hardware components such as Application Specific Integrated Circuits (ASICs).

[0133] Figure 6 is a flowchart illustrating the operation of a light-emitting device according to one embodiment of the present disclosure.

[0134] In operation 600, the light-emitting device 500 can identify its operating mode. In one embodiment, the operating mode of the light-emitting device 500 can be set by user settings. For example, the user can set the light-emitting device 500 to operate in a first mode or a second mode by operating the input section of the light-emitting device 500 (e.g., a button, a switch, etc.). In another embodiment, the light-emitting device 500 can operate in a first mode in response to receiving a light-emitting control signal from the master device 300 of the performance venue. In this case, the light-emitting device 500 can normally operate in a second mode.

[0135] In operation 610, if the operating mode of the light-emitting device 500 is the first mode, the process can proceed to operation 620. In operation 620, the light-emitting device 500 can receive a light-emitting control signal from an external electronic device of the performance venue (e.g., a master device 300) via the communication unit 510. In operation 625, the light-emitting device 500 can perform a light-emitting operation based on at least one of the light-emitting hue, light-emitting pattern, and light-emitting intensity indicated by the received light-emitting control signal.

[0136] In operation 610, if the operating mode of the light-emitting device 500 is the 2-1 mode, the sound source 400 can be received and recognized via the sensing unit 580, a sound source identical to the recognized sound source 400 can be searched for in the database, and a light-emitting operation can be performed based on at least one of the light-emitting hue, light-emitting pattern, and light-emitting intensity indicated by the light-emitting control information mapped to the searched sound source.

[0137] Furthermore, in operation 610, if the operating mode of the light-emitting device 500 is mode 2-2, the process can proceed to operation 630. In operation 630, the light-emitting device 500 can receive a sound source 400 via the sensing unit 580, which includes control information 410, synchronization information 420, and / or sound source information 430. In operation 632, the light-emitting device 500 can extract the control information 410 and synchronization information 420 from the sound source 400. In operation 634, the light-emitting device 500 can perform a light-emitting operation based on at least one of the emission hue, emission pattern, and emission intensity based on the control information 410 and synchronization information 420. On the other hand, the disclosed embodiment can be embodied in the form of a recording medium that stores computer-executable instruction words. The instruction words may be stored in the form of program code, which, when executed by a processor, can generate a program module to perform the operations of the disclosed embodiment. The recording medium can be a computer-readable recording medium.

[0138] Computer-readable recording media include all types of recording media that store computer-decipherable instruction words. Examples include ROM (Read Only Memory), RAM (Random Access Memory), magnetic tape, magnetic disks, flash memory, and optical data storage devices.

[0139] The disclosed embodiments have been described above with reference to the attached drawings.
