[0031] Hereinafter, embodiments related to the present disclosure will be described in more detail with reference to the accompanying drawings. In the following description, the suffixes "...module" and "...unit" used in this document for constituent elements are given or used interchangeably only for the purpose of facilitating the preparation of the description, but the suffixes do not have mutually distinguishing meanings or functions. In this specification, a device that is carried by or provided to an individual, emits light in various modes and includes an auxiliary vibration function is referred to as a light-emitting device. The light-emitting device can be owned by a user watching a performance in a performance hall or concert, or can be fixed to each user's seat to be provided to the user.

[0032] The way a light-emitting device emits light, flashes, or additionally vibrates is referred to as a pattern, and a combination of one or more patterns is referred to as a scene. A scene allows the light output by the light-emitting device to represent an image designed by the creator. For example, a scene can correspond to a song. Therefore, the playback time of a scene can be equal to the playback time of a song.

[0033] A scene can be composed of multiple libraries. Each of the multiple libraries can correspond to a partial playback interval of the scene. The scene data can include information required to execute the scene. The scene data can include multiple library data.

The processor 57 can control the light source unit 56 to operate according to the determined library. In particular, based on the library identification information included in the control message, the processor 57 can search for a mode corresponding to the library identification information through the storage unit 52 and can control the light source unit 56 to output the corresponding mode.

[0111] Figure 8 FIG. 1 is a ladder diagram illustrating an operational relationship among a central server, a mobile terminal, and a lighting device according to an embodiment of the present disclosure.

[0112] The central server 5 acquires scenario data and firmware capable of executing a scenario corresponding to the scenario data ( S801 ), and transmits the acquired scenario data and firmware to the mobile terminal 60 ( S803 ).

[0113] The mobile terminal 60 stores the scene data and firmware received from the central server 5 ( S805 ).

[0134] A scene 1000 may include multiple libraries 1010, 1020, 1030, 1040, and 1050. The scene creator can design the scene by dividing the total playback time of a song into multiple intervals through the control device 20 or the central server 5. Assume that the total playback time of a song is four minutes. These multiple intervals may correspond to the multiple libraries 1010 to 1050, respectively. The first library 1010 may indicate that the light source units 56 of all lighting devices should be turned off for 10 seconds from the start of the song. The second library 1020 may indicate that the light source units 56 of all lighting devices should be turned on for 20 seconds after the execution of the first library 1010. The third library 1030 may indicate that the light source units 56 of all lighting devices should perform a strobe operation for one minute after the execution of the second library 1020. The fourth library 1040 may indicate that the light source units 56 of all lighting devices should emit light to represent the singer's logo for two minutes after the execution of the third library 1030. The fifth library 1050 may indicate that the light source units 56 of all lighting devices should be turned off within 30 seconds after executing the fourth library 1040. As described above, a scene can be completed by a combination of the first to fifth libraries 1010, 1020, 1030, 1040, and 1050.

[0135] The control message that the control device 20 sends to all the lighting devices through the sending device 30 and the plurality of repeaters 40 - 1 to 40 - n may be a scene execution command.

[0136] In another embodiment, the control message transmitted by the control device 20 to all the lighting devices through the transmitting device 30 and the plurality of repeaters 40 - 1 to 40 - n may be a command for executing one library constituting a scene.

[0137] Reference Figure 11 , shows the structure of scene data 1100 corresponding to scene 1000.

[0138] Scene data 1100 may include a header 1110, a palette field 1120, and a plurality of library fields 1130-1 to 1130-n. The palette field 1120 may include information about a color table capable of representing 256 colors. The color table may include index values ​​corresponding to the 256 colors, respectively. In this case, the color table may have a size of 1 byte.

[0139] Library data described later may include index values ​​included in the color table.

[0140] Each of the plurality of library fields 1130-1 to 1130-n may include a library header and library data. For example, the first library field 1130-1 may include a first library header 1130-1a and first library data 1130-1b. The first library data 1130-1b may correspond to Figure 10 Each library data may include information on one or more of group identification information, library identification information, light-emitting group operation start time, light-emitting group operation end time, color information that should be output by the light-emitting group, and a pattern that should be output by the light-emitting group.

[0141] Will refer to Figure 12 Describes in detail the information contained in each library data.

[0142] Figure 12 A diagram illustrating information included in scene data according to an embodiment of the present disclosure.

[0143] Reference Figure 12 , the scene data 1200 may include a plurality of library data 1210 to 1250 .

[0144] The group identification information is information for identifying that a plurality of light-emitting devices disposed in a space are divided into n groups and each light-emitting group performs a different operation.

[0145] Group identification information can be used as a reference for identification Figure 1The information of the above-mentioned light-emitting groups. If the group identification information is "ALL", it can be instructed that all light-emitting groups execute the same library. Library identification information is information included when the control device 20 commands each light-emitting device to operate according to a specific library. For example, if the control device 20 sends a control message "library 002 operation", the light-emitting device executes "002" in the library identification information. In the case where the light-emitting devices are divided into multiple groups, the light-emitting device 50 can operate according to the configured group number. For example, in the same way, if the light-emitting device 50 belongs to the first light-emitting group GROUP1 and receives the command message "library 002 operation" from the control device 20, the light-emitting device 50 can execute the corresponding mode "R / GRAD_10 / B / Repeat60". In addition, if the light-emitting device 50 belongs to the second light-emitting group GROUP2 and receives the command message "library 002 operation" from the control device 20, the light-emitting device 50 can execute the corresponding mode "B / GRAD_30 / G / Repeat 60". Furthermore, if lighting device 50 belongs to the third lighting group GROUP3 and receives the command message "Bank 002 Operation" from control device 20, lighting device 50 may execute the corresponding mode "G / GRAD_30 / R / Repeat60." "Start Time" may indicate the time when the bank is executed. If the Start Time is "NULL," it means that the corresponding bank is operating according to the control message from control device 20.

[0146] The mode may indicate the color, lighting time, repetition period, or blinking or off period of light emitted by the light source unit 56. R, G, and B indicate red, green, and blue, respectively.

[0147] In the case where the light source unit 56 can adjust the light more accurately, the light source unit 56 can output a color obtained by combining R, G, and B. In the case of RGB 256 color indication, each of R, G, and B can be defined as 1 byte (8 bits), and when defining RGB, 3 bytes may be required to display RGB. The color of the light output by the light source unit 56 can be configured in various types (for example, RGB, R / G / B, or a specific binary number or hexadecimal number).

[0148] In addition, the light source can be turned on / off and the holding time (in seconds) can be recorded together. In addition, the number of repetitions or the repetition time can be configured as REPEAT. "GRAD" indicates that the light output by the light source unit 56 has a pattern in which the light gradually changes. In an embodiment, the library "002" of the first light-emitting group is "R / GRAD_10 / B / REPEAT_60", which means that the color of the light output by the light-emitting device 50 gradually changes from red to blue in 10 seconds, and such a change is repeated 60 times (or repeated for 60 seconds).

[0149] The “BLINK” indicator flashes.

[0150] In addition, although not Figure 12 , but “strobing” may indicate flashing at a higher speed than “flashing”.

[0151] 13A and 13B are diagrams illustrating an example in which a lighting device controls timing according to repeated reception of a control message according to an embodiment of the present disclosure.

[0152] The control message may be transmitted to the lighting apparatus 50 via the repeater 40 in a broadcast method. In the case of using a unicast method instead of a broadcast method, the transmitting device 30 needs to receive a confirmation message corresponding to the reception of the transmitted control message from the lighting apparatus 50. In this case, if confirmation messages are received from a large number of lighting apparatuses, the communication condition may deteriorate.

[0153] Therefore, in the embodiment of the present disclosure, the transmitting device 30 transmits the control message to the lighting device 50 in a broadcast method.

[0154] 13 , the transmitting device 30 may repeatedly transmit a control message indicating an execution command of a specific library to the light emitting device 50 five times.

[0155] The transmitting device 30 may sequentially transmit the zeroth to fourth control messages 1301 to 1305 to the light emitting device 50. The zeroth to fourth control messages 1301 to 1305 may be sequentially transmitted to the light emitting device 50 in a predetermined period.

[0156] Each of the zeroth to fourth control messages 1301 to 1305 may include the same repository identification information. However, each control message may have a different sequence number. For example, when the zeroth to fourth control messages 1301 to 1305 are sent sequentially, the sequence number may be incremented by 1. The sequence number may indicate the transmission interval between sequentially transmitted control messages. The transmission interval between each control message may be 0.4 seconds, but this is merely an example.

[0157] The reason for sequentially transmitting the five control messages 1301 to 1305 is to control the timing differences between the lighting groups or lighting devices in the lighting groups to be finer, in the event that a control message may be missed depending on the communication situation. The missed transmission of a control message may indicate that the lighting device 50 is unable to receive the control message.

[0158] 13B , a graph shows a pattern that should be executed by the light emitting device 50 within the execution time of one library.

[0159] If it is assumed that the execution time of one library is 3 seconds, the light emitting device 50 does not output blue and green (see 1303 and 1305), but gradually outputs red for 1 second and then maintains this output for the remaining 2 seconds (1301). The initial 0.5 second period is magnified for illustration.

[0160] The first red mode graph 1331 shows that when the first light-emitting device receives the zeroth control message 1301 , the first light-emitting device gradually increases and outputs red light according to the zeroth control message 1301 .

[0161] The second red mode graph 1333 shows that when the second light emitting device cannot receive the zeroth control message 1301 and the first control message 1302 , the second light emitting device gradually increases and outputs red light according to the second control message 1303 .

[0162] The third red mode graph 1335 shows that in a case where the third light emitting device cannot receive the zeroth to second control messages 1301 to 1303 , the third light emitting device gradually increases and outputs red light according to the third control message 1304 .

[0163] The time required to sequentially transmit the five control messages 1301 to 1305 is very short. Therefore, even if some lighting devices fail to receive the initial control message, they can immediately execute the library upon receiving subsequent control messages. Furthermore, the five control messages 1301 to 1305 include sequence numbers indicating the transmission interval. Lighting devices 50 that did not receive the initial control messages can use the sequence numbers included in the control messages to control the execution timing of the library. Using the sequence numbers, it is possible to finely control the timing differences between the operations of individual lighting devices 50.

[0164] 14A to 14C are diagrams illustrating an example in which a lighting device controls timing according to repeated reception of a control message and reception of a synchronization packet according to an embodiment of the present disclosure.

[0165] In Figures 14A to 14C, it is assumed that the execution time of one library is 3 seconds. In addition, it is assumed that the bundle of five control messages indicating the execution command of the library is a retransmission packet 1400. The five control messages have been described with reference to Figures 13A and 13B. After sending the retransmission packet 1400, the transmitting device 30 can send a synchronization packet 1410 to each light-emitting device in each predetermined time period. In addition, the synchronization packet can be a packet used to check whether each light-emitting device 50 is well following the execution of the library. The synchronization packet can include information about a time point of the library and information about a mode that should be executed at a corresponding time point to match the operation synchronization between the various light-emitting devices 50.

[0166] FIG. 14A shows a graph in which a first light emitting device receives a retransmission packet 1400 and a synchronization packet 1410 and outputs a pattern corresponding to a library.

[0167] 14B shows a graph in which the second light emitting device fails to receive the retransmission packet 1400 but receives the first synchronization packet 1410 and outputs a pattern corresponding to the library from the time point of receiving the first synchronization packet 1410 .

[0168] As shown in FIG. 14B , even in the case where the second light emitting apparatus cannot receive the retransmission packet 1400 , the second light emitting apparatus can execute the library from the time point of receiving the first synchronization packet 1410 through the subsequent first synchronization packet 1410 .

[0169] 14C shows a graph in which the third light emitting device receives the retransmission packet 1400 and the first synchronization packet 1410 but fails to receive the second synchronization packet 1430 and outputs a pattern corresponding to the library.

[0170] As shown in FIG. 14C , even in the case where the third light-emitting device cannot receive the second synchronization packet 1430 , the third light-emitting device can correctly execute the library through the previously received retransmission packet 1400 .

[0171] As described above, according to the embodiment of the present disclosure, even if the lighting apparatus 50 cannot receive a control message for executing a library, the lighting apparatus 50 can immediately execute the library through a synchronization packet and thus can effectively match synchronization with other lighting apparatuses.

[0172] Next, the operation mode of the light emitting device will be described.

[0173] Figure 15 A diagram illustrating an initialization operation when a light emitting device is turned on according to an embodiment of the present disclosure.

[0174] Hereinafter, it is assumed that the operating modes of the lighting device 50 include an RF mode 1510, a BLE mode 1530, and a standalone mode 1550. The RF mode 1510 may be a mode for performing communication with the repeater 40 using a communication protocol such as ZigBee. The BLE mode 1530 may be a mode for performing communication with the mobile terminal 60 using a low-power Bluetooth module. The standalone mode 1550 may be a mode in which the output of the light source unit 56 can be turned on / off without communicating with an external device.

[0175] Reference Figure 15, if the power of the light emitting device 50 is turned on, the light emitting device 50 operates in RF mode 1510. After 5 seconds, the operation mode of the light emitting device 50 may be switched from RF mode 1510 to BLE mode 1530. Again, after 25 seconds, the operation mode of the light emitting device 50 may be switched from BLE mode 1530 to RF mode 1510. Although this cycle is repeated n times, if the light emitting device 50 cannot receive the heartbeat MSG message from the repeater connected to the mobile terminal 60BLE, the operation mode of the light emitting device 50 may be switched to standalone mode 1550. The reason for changing the operation mode of the light emitting device 50 during the power initialization process is to determine whether it is possible to participate in the performance by changing the operation mode, because the RF protocol cannot be used simultaneously when multiple RF stacks are used.

[0176] Next, we will describe Figure 16 .

[0177] Figure 16 Flowchart for explaining the operation process of the guidance type lighting device according to an embodiment of the present disclosure. Figure 16 , the lighting device 50 receives a performance preparation message in the RF mode (S1601).

[0178] In an embodiment, the lighting device 50 may receive a performance preparation message from the repeater 40 via the control device 20. The performance preparation message may be a message for preventing switching to standalone mode. If a user enters the performance hall and performs operations separate from the library by operating the lighting device 50 in standalone mode, guidance by the lighting device may not be properly performed. To this end, the performance preparation message may be sent to each lighting device 50 to prevent the user from arbitrarily controlling the lighting device 50. Upon receipt of the performance preparation message, the lighting device 50 prevents switching to standalone mode (S1603).

[0179] In an embodiment, the lighting device 50 may switch from RF mode to BLE mode upon receiving a performance preparation message. This is because the lighting device 50 may need to receive library data or scene data from the mobile terminal 60. The lighting device 50 determines whether the performance type is integration guidance based on the performance identifier included in the performance preparation message (S1605).

[0180] In an embodiment, if the performance type is integrated guidance, all lighting devices can be collectively controlled under the control of the control device 20. In this case, the lighting devices 50 do not need to store library data. This is because the message sent by the control device 20 can include detailed operation content of the lighting devices 50 (turning light output on or off).

[0181] If the performance type is integrated guidance, the lighting device 50 operates in RF mode (S1607). Therefore, the lighting device 50 prepares to receive a control message from the control device 20. If the performance type is individual guidance, the lighting device 50 determines whether the concert identifier included in the performance preparation message is stored (S1609). If the performance type is individual guidance, the lighting device 50 can search whether the concert identifier included in the performance preparation message is stored in the library data of the storage unit 52. If the concert identifier included in the performance preparation message is stored, the lighting device 50 operates in RF mode (S1607). If the concert identifier is not stored in the performance preparation message, the lighting device 50 obtains the library data including the corresponding concert identifier from the mobile terminal 60 (S1611). That is, according to Figure 8 In the embodiment, the lighting device 50 may receive library data from the mobile terminal 60. Next, operations of the lighting device 50 depending on whether the lighting device 50 and a bracket capable of mounting the lighting device 50 are docked with each other will be described.

[0182] 17A and 17B are diagrams illustrating an operation of the light emitting device in a case where the light emitting device and the bracket are not docked with each other according to an embodiment of the present disclosure.

[0183] The bracket 1700 may be a device capable of supplying power provided from the outside to the light emitting device 50 when the light emitting device 50 is mounted on the bracket 1700 .

[0184] 17A , the light emitting device 50 and the bracket 1700 are separated from each other, and the power of the light emitting device 50 is in an off state.

[0185] 17B, ​​the lighting device 50 and the bracket 1700 are separated from each other, and the power of the lighting device 50 is in an on state. If the lighting device 50 operates in a standalone mode in the power-on state, four cheering modes can be supported.

[0186] The four cheering modes may respectively correspond to the plurality of keys 58a to 58d provided on the lighting device 50. If any one of the plurality of keys 58a to 58d is selected, the lighting device 50 may control the operation of the light source unit 56 to operate in the cheering mode corresponding to the selected key.

[0187] Next, the operation of the light emitting device 50 in a case where the light emitting device 50 and the bracket 1700 are docked with each other will be described.

[0188] 18A and 18B are views illustrating an operation process of the light emitting device in a case where the light emitting device and the bracket are docked with each other according to an embodiment of the present disclosure.

[0189] In particular, FIG. 18A illustrates an operation process under the assumption that the light emitting device 50 and the cradle 1700 are docked with each other and the mobile terminal 60 does not exist nearby.

[0190] When the lighting device 50 and the cradle 1700 are docked with each other, the lighting device 50 may output a light pattern indicating that the cradle 1700 is connected to the lighting device 50 (S1801). Thereafter, the lighting device 50 may activate the BLE mode (specifically, the beacon mode) and may transmit a beacon signal to the outside in a broadcast method using the AltBeacon protocol (S1803).

[0191] 18B , after operations S1801 and S1803 are performed, the lighting apparatus 50 may be connected to the mobile terminal 60 in response to a beacon signal ( S1805 ).

[0192] In a case where the light emitting device 50 is connected to the mobile terminal 60, the light emitting device 50 may output light indicating a welcome sign (S1807).

[0193] In a case where the mobile terminal 60 is connected to the light emitting device 50 , the mobile terminal 60 may transmit a command for outputting light indicating a welcome sign to the light emitting device 50 .

[0194] Thereafter, the lighting device 50 waits for deviation from the beacon signal recognition range (S1809), that is, the lighting device 50 recognizes that there is no mobile terminal 60 nearby, and if there is no mobile terminal 60 nearby, the lighting device 50 waits for a predetermined time (S1811).

[0195] Although it has been described that all constituent elements constituting an embodiment of the present disclosure are combined into one or combined to operate, the present disclosure is not necessarily limited to such an embodiment, but one or more of all constituent elements may be selectively combined and operated within the scope of the purpose of the present disclosure.

[0196] In addition, although each of all the constituent elements can be implemented as an independent hardware, some or all of the constituent elements can be selectively combined to implement a computer program having a program module that performs some or all of the functions of one or more hardware combinations. Those skilled in the art to which the present disclosure belongs can easily infer the codes and code segments constituting the computer program.

[0197] Such a computer program can be stored in a computer-readable medium and can be read and executed by a computer to implement the embodiments of the present disclosure. Computer program storage media include storage media including magnetic recording media, optical recording media, and semiconductor recording devices. In addition, the computer program that implements the embodiments of the present disclosure includes program modules that are transmitted in real time via an external device.

[0198] Although the present disclosure has been described with reference to the embodiments of the present disclosure, various modifications and changes can be made thereto at the level of ordinary technicians. Therefore, it should be understood that unless these modifications and changes depart from the spirit and scope of the present disclosure, they are all included within the scope of the present disclosure.
