Background Art

[0002] The content described below only provides background information related to this embodiment and does not constitute the prior art.

[0003] Generally, a light-emitting device (or lighting device) may mean 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.

[0004] With the development of technology, light-emitting devices are used in various applications. As an example, a light-emitting device can be provided on the outer wall of a building and used to produce a media facade that realizes a media function. As another example, a light-emitting device can be used as a portable cheering tool in a performance venue such as a sports competition or a concert where the environment is below a certain illuminance.

[0005] A master device that integrally controls the light-emitting devices arranged in a performance venue transmits a control signal for performance production to the light-emitting devices in a broadcast manner, but in a large-scale performance venue, due to communication overload, restrictions may occur in performance production.

[0006] Therefore, a method for improving this is needed.

[0008] Another object of the present invention is to provide effective performance staging without directly controlling the light-emitting device by identification information mapped to the device or group.

[0009] Furthermore, another object of the present invention is to provide a light-emitting device that performs autonomous performance effects using a pre-stored random function.

[0039] In this specification, the "control device for random performance staging at a performance venue relating to this disclosure" can be implemented not only as a cloud system but also as a variety of devices capable of performing computational processing and providing results to the user. For example, the control device for random performance staging at a performance venue relating to this disclosure may include a computer, a server device, and a portable terminal, or it may take any one of these forms.

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0041] Figure 1 is a schematic diagram illustrating the light emission control system 1000 for performance staging at a performance venue according to this disclosure, and Figure 2 is a diagram illustrating the shape of the light emission device 100 according to this disclosure.

[0042] Referring to Figure 1, the light emission control system 1000 according to this disclosure may include a control device 200 and light emission devices for cheering (100A, 100B, ..., 100N, hereinafter "100"). Such a light emission control system 1000 can produce a variety of light emission patterns for performance effects, such as cheering in the audience seats of a performance venue, by having the control device 200 control the light emission state of the light emission devices 100.

[0043] The control device 200 can perform the function of controlling the light-emitting device 100 for performance effects at the performance venue. The control device 200 can operate in connection with a central control device, or it can be configured as part of the central control device. Furthermore, the control device 200 can receive signals from the central control device and operate in synchronization with sound equipment, lighting equipment, etc., within the performance venue, thereby synchronizing the light-emitting device 100 with the sound equipment, lighting equipment, etc., to automatically perform the performance.

[0044] The control device 200 can include a variety of electronic devices, including mobile phones, smartphones, and laptop computers, and can also include a variety of electronic devices, including MA Lighting grandMA2. The control device 200 can include a simulator for creating lighting effects. The simulator can include a variety of electronic devices for realizing virtual simulations to achieve lighting effects. The simulator can store a variety of scenarios in a predetermined state or allow users to input them.

[0045] Furthermore, the control device 200 may include appropriate software or computer programs that enable control of the light-emitting device 100. For example, the control device 200 may include exemplary protocols for controlling the light-emitting device 100, such as DMX512, RDM, Art-Net, sACN, ETC-Net2, Pathport, Shownet, or KiNET.

[0046] The control device 200 may further include an antenna for emitting light emission control signals. The control device 200 may further include, according to 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.

[0047] The control device 200 may include a master device. The master device may be provided for efficient signal transmission at the performance venue. The master device may include a database DB. The master device may provide the control signals to the transmitter, including information from the database DB, or provide them directly to the light-emitting device 100.

[0048] The light-emitting device 100 can perform functions to produce various forms of light-emitting patterns in real time or according to predetermined control information, controlled by the control device 200. In this embodiment, the light-emitting device 100 includes or can be connected to light-emitting elements such as an LCD (Liquid Crystal Display) or an LED (Light Emitting Diode).

[0049] Figure 2 illustrates the shape of the light-emitting device 100 according to this disclosure.

[0050] Referring to Figure 2, the light-emitting device 100 can be realized in a form that can be worn on a body part (e.g., the wrist) (100C, 100D). Alternatively, the light-emitting device 100 can be realized in a form that is held by the user supporting the project (100E).

[0051] Furthermore, the light-emitting device 100 is a device that includes 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 100 can be a mobile phone, a wireless light-emitting device, a lighting stick, a lighting bar, a lighting ball, a lighting panel, or an object to which a wirelessly controllable light source is attached.

[0052] The performance venue where the light-emitting device 100 is installed is a place for performances such as sports competitions or concerts, and can consist of, for example, a stage or stadium, seating areas, etc. The performance venue may also be equipped with various devices necessary for the performance (for example, sound equipment, lighting equipment, etc.) and may include a central control device, such as a control console that can adjust and control the operation of such devices.

[0053] Figure 3 is a relative block diagram showing the configuration of the light-emitting device 100 and control device 200 according to this disclosure.

[0054] Referring to Figure 3, the light-emitting device 100 can be used for random performance effects at a performance venue and may include a communication unit 110, a light-emitting unit 120, a memory 150, and a control unit 190. Since the components of the light-emitting device 100 shown in Figure 3 are not essential for realizing the light-emitting device 100 according to this disclosure, the light-emitting device 100 described herein may have more or fewer components than those listed above.

[0055] Of the aforementioned components, the communication unit 110 can communicate with a variety of devices equipped with communication modules. The communication unit 110 may include at least one of the following: a broadcast receiving module, a wired communication unit, a wireless communication unit, a short-range communication module, and a location information module. That is, the communication unit 110 can communicate with external devices based on wired or wireless connections.

[0056] The light-emitting unit 120 can perform a light-emitting operation for cheering using one or more light-emitting elements.

[0057] Memory 150 can store the random function RA. Memory 150 can store data supporting the various functions of the light-emitting device 100, programs for the processor's operation, input / output data (e.g., music files, still images, videos, etc.), numerous application programs (applications) driven by the light-emitting device 100, data for the server's operation, and instruction words. At least some of these application programs can be downloaded from an external server via wireless communication. Memory 150 can store one or more instructions and can include various deep learning-based models.

[0058] If the control unit 190 has a random function RA stored in the memory 150 in advance for randomly staging the light-emitting operation of the light-emitting unit 120 within a predetermined range, it can execute the random function RA in accordance with the trigger command of the control device 200 to randomly staging the light-emitting operation.

[0059] In this embodiment, the control unit 190 can execute the random function RA if there are no direct control commands or reserved control commands (excluding the execution of the random function) from the control device 200 for a predetermined period of time (i.e., if a predetermined period of time has elapsed during which the control device 200 is not controlling the system). The random function RA can randomly produce and output at least one of the emission color, emission pattern, and / or emission intensity within its own constraints (e.g., within a predetermined range).

[0060] Here, the random function RA allows the light-emitting unit 120 to be controlled to perform light-emitting operations randomly within certain constraints, rather than the light-emitting device 100 performing light-emitting operations completely randomly. In some implementations, the light-emitting unit 120 can be made to perform light-emitting operations completely randomly.

[0061] If the random function RA is not pre-stored in the memory 150, the control unit 190 can receive and execute the random function RA from the control device 200 to randomly produce the light-emitting operation. For example, the control device 200 can provide the random function RA to the light-emitting device 100 during a performance.

[0062] In this case, the control unit 190 can provide the light-emitting device 100 with control patterns for light emission operation parameters such as light emission color, light emission pattern, and light emission intensity sequentially, including them in a random function RA, rather than in the form of a function / procedure, in order to prevent communication overload, but the embodiment is not limited to this.

[0063] In this embodiment, the control unit 190 can randomly produce at least one of the emission color, emission pattern, and emission intensity within a predetermined range based on the random function RA.

[0064] The memory 150 of the light-emitting device 100 does not need to store group assignment information for group-specific performance productions.

[0065] In this case, the random function RA can randomly produce at least one of the emission color, emission pattern, and emission intensity within a predetermined range. Here, the predetermined range can mean that a predetermined limiting condition is set for at least one of the emission color, emission pattern, and emission intensity. Several embodiments will be described below, but this disclosure is not limited thereto.

[0066] In this embodiment, the random function RA can randomly display two or more light-emitting colors from among the light-emitting colors that the light-emitting device 100 can output, and then only within the selected light-emitting colors. In this case, the light-emitting device 100 can randomly display a variety of light-emitting patterns (time, period, pattern, sequence, flashing, etc.) and / or light-emitting intensity (maximum, minimum, gradual increase, gradual decrease, flashing, etc.), in addition to the light-emitting color. In this case, it is also possible to set restrictions on some of the light-emitting patterns and / or light-emitting intensity.

[0067] In the embodiment, the random function RA can set the luminescence intensity to a specific value at a predetermined time, or can gradually change it at a predetermined time. In the embodiment, the light-emitting device 100 can recognize a sound and output the luminescence intensity according to the pitch and / or duration of the recognized sound, but the disclosure is not limited thereto.

[0068] In this embodiment, group assignment information for performance direction by group can also be stored in memory 150.

[0069] At this time, the control unit 190 can selectively receive, via the communication unit 110, control commands that correspond to group assignment information from among the control commands for group-specific light emission control broadcast within the performance venue.

[0070] Furthermore, when the control unit 190 randomly performs the light-emitting operation, it can reflect control commands corresponding to the group assignment information. For example, if the control unit 190 receives a group control command from the control device 200 while randomly performing the light-emitting operation, it can randomly reflect the received group control command in the performance. In this embodiment, the control unit 190 can assign a priority to group control commands or random control commands, and follow either group control or random performance control according to the set priority, and the priority can be changed by the control device 200.

[0071] As described above, the control device 200 can be implemented in various ways. The control device 200 may include a communication module 210, a storage module 250, and a control module 290. The components of the control device 200 shown in Figure 3 are not essential for implementing the control device 200 according to this disclosure; therefore, the control device 200 described herein may have more or fewer components than those listed above.

[0072] The control device 200 can communicate with one or more light-emitting devices 100 via a communication module 210 for random performance effects at the performance venue. The communication module 210 can communicate with a variety of devices equipped with communication modules. The communication module 210 may include at least one of the following: a broadcast receiving module, a wired communication unit, a wireless communication unit, a short-range communication module, and a location information module. That is, the communication module 210 can communicate with external devices based on wired or wireless connections.

[0073] The control device 200 can store various types of information in the storage module 250 under the control of the control module 290. The control module 290 may include memory, cache, buffers, etc., but the embodiment is not limited to this.

[0074] The storage module 250 can store data that supports the various functions of the control unit 200, programs for the operation of the processor, input / output data (e.g., music files, still images, videos, etc.), and numerous application programs (applications) driven by the control unit 200, data for the operation of this server, and instruction words. At least some of these application programs can be downloaded from an external server via wireless communication. The storage module 250 can store one or more instructions and can include various deep learning-based models.

[0075] The control device 200 may further include a display in addition to the configuration described above. The display shows (outputs) information processed by the control device 200. For example, the display can show execution screen information of an application program (for example, an application) driven by the control device 200, or UI (User Interface) or GUI (Graphic User Interface) information based on such execution screen information.

[0076] The control module 290 may include a configuration that recognizes the light output of the seats in the performance venue, and can output the light output status to a display based on the recognized light output. In addition, the control module 290 can use the light output recognition module to determine whether or not the group control of the control device 200 can be reflected.

[0077] The control module 290 generates performance scenes using the light-emitting devices 100 for cheering purposes during performances at the concert venue. The light-emitting devices 100 can be operated randomly within a predetermined range, rather than being controlled centrally. This allows for more effective communication in areas with high traffic congestion, leading to a greater focus on the performance.

[0078] If the light-emitting device 100 has a random function pre-stored in it for randomly staging the light-emitting operation of the light-emitting device 100 within a predetermined range, the control module 290 can provide the light-emitting device 100 with a trigger command via the communication module 210 to execute the random function during the performance.

[0079] If the control module 290 does not have a random function pre-stored in the light-emitting device 100, it can provide the random function to the light-emitting device 100 using the communication module 210.

[0080] If the light-emitting device 100 stores group assignment information for group-specific performance staging, the control module 290 can broadcast control commands for group-specific light emission control within the performance venue via the communication module 210.

[0081] In this embodiment, if both light-emitting devices storing group assignment information (assuming that the light-emitting devices forming a group are located within the same group) and light-emitting devices not storing group assignment information are placed within the performance venue, the control module 290 can randomly activate the light-emitting operation of the light-emitting devices 100 within a predetermined range at a predetermined time, and transmit group control commands only to the light-emitting devices storing group assignment information. For example, if the group control command is related to forming a human character, the control module can transmit the group control command only to the seats corresponding to the human character, and randomly activate the light-emitting operation for the other seats.

[0082] In this case, the control module 290 can use the light output recognition module to monitor whether the light output of the light-emitting devices 100 included in the group is operating as intended, and if it is not outputting as intended, it can sequentially control each group so that it produces the intended light output. The light output recognition module may include a light receiving sensor, an image sensor, etc., and the control module 290 can also execute an image recognition algorithm.

[0083] In this embodiment, the group assignment information pre-stored in the light-emitting device 100 can be used to define the entire seating area of ​​a performance venue by introducing and applying a virtual coordinate system. A single seat in a seating area may have specific x and y coordinate values, and multiple adjacent seats may have the same x and y coordinate values. In addition, the position of seats in the audience can be determined by introducing other forms of coordinate systems besides the commonly used x and y coordinate system.

[0084] When some or all of the group assignment information stored in the light-emitting device 100 in advance is recorded as coordinate information, the performance mapping data transmitted in real time at the performance site can include control signals that cause light-emitting devices 100 belonging to a range of coordinate values ​​to emit a specific color, based on one or more specific coordinate values ​​or a specific coordinate range, in order to identify light-emitting devices 100 that emit a specific color. That is, when group assignment information and group emission color information are mapped to each other to constitute performance mapping data, coordinate values ​​or coordinate ranges can be provided instead of group assignment information. In this case, the light-emitting device 100 receives the performance mapping data during the performance, determines whether it is included in specific group assignment information based on the coordinate values ​​to which it belongs, and emits light in the appropriate color accordingly. When group information based on a coordinate system set for the entire audience seating area of ​​the performance venue is stored in the light-emitting device 100 in advance, even small-scale data transmission makes it possible to create improvisational lighting effects for the audience seating area. That is, by generating or modifying and broadcasting performance mapping data to cause only the light-emitting devices 100 within a specific coordinate range to emit a predetermined color, variable lighting effects for the audience seating area become possible.

[0085] In the embodiment, the performance mapping data transmitted in real time at the performance venue may further include dimming information necessary for each group to emit light in the corresponding color. For example, when Group A emits light in a specific color during a specific performance section (audience seating scene), if the lights must be turned on and off at specific time intervals, transmitting the on and off signals each time would result in a large amount of signals being broadcast in a short time, potentially causing processing delays as the amount of signals that the receiving light-emitting device 100 must process increases. If the blinking interval becomes shorter, for example, to 0.5 seconds or less, due to the characteristics of real-time signal processing, a predetermined delay may occur, potentially resulting in unnatural performance scenes. Therefore, by transmitting the performance mapping data only once at the initial start of a specific performance section where blinking is to occur, and including information regarding the blinking interval and duration within the performance mapping data, the light-emitting device 100 belonging to the specific group that receives this data can realize a cheering lighting effect by blinking at the promised time.

[0086] Figure 4 is a sequence diagram illustrating an embodiment in which the random function according to this disclosure is stored in the light-emitting device 100, and Figure 5 is a sequence diagram illustrating an embodiment in which the random function according to this disclosure is not stored in the light-emitting device 100.

[0087] Referring to Figure 4, the light-emitting device 100 can store a random function in advance (S410).

[0088] The control device 200 can transmit a trigger command to the light-emitting device 100 so that the light-emitting device 100 performs random effects within a predetermined range at predetermined points during the performance (S420).

[0089] The light-emitting device 100 can perform random light-emitting actions by executing a random function (S430).

[0090] Referring to Figure 5, if the light-emitting device 100 does not have a random function stored in it beforehand (S510), the control device 200 can transmit a random function to the light-emitting device 100 (S520).

[0091] The light-emitting device 100 can perform random light-emitting actions by executing a random function (S530).

[0092] Figure 6 illustrates a random function used to randomly produce the light emission operation related to this disclosure.

[0093] The control unit 190 of the light-emitting device 100 can use a random function RA to control the light-emitting operation.

[0094] The control unit 190 can control only one (or part of) of the emission color, emission pattern, and / or emission intensity, and randomly set the other emission operations.

[0095] Here, the emission color 610 can include red, black, white, yellow, and blue, but the emission color is not limited to the examples.

[0096] The light emission pattern 620 may include (light emission) time, period, pattern, sequence, and flashing, but the light emission pattern is not limited to the embodiment.

[0097] The luminescence intensity 630 can be selected from (luminescence) maximum, minimum, gradual increase, gradual decrease, and flashing, but the embodiments are not limited to these.

[0098] The control unit 190 can randomly produce light emission operations of the light emission unit 120 by controlling the light emission color 610, light emission pattern 620, and light emission intensity 630.

[0099] On the other hand, the disclosed embodiments can be implemented in the form of a recording medium that stores computer-executable instruction words. The instruction words can be stored in the form of program code, and when executed by a processor, a program module can be generated to perform the operations of the disclosed embodiments. The recording medium can be implemented as a recording medium that can be read by a computer.

[0100] Computer-readable storage media include all types of storage media that store instruction words that can be deciphered by a computer. Examples include ROM (Read Only Memory), RAM (Random Access Memory), magnetic tape, magnetic disks, flash memory, and optical data storage devices.

[0101] As described above, the embodiments disclosed have been explained with reference to the attached drawings.
