The present disclosure relates to a lighting device and a performance system including the same.
Lighting devices may be deployed in a performance hall, a music concert, or an art gallery where many people gather, in order to guide a performance, to instruct a movement in a space, or for aesthetic cheer.
In particular, a lighting device provided to each individual may operate in a different manner in accordance with a specific location in the space or the individual to which the lighting device is provided.
In case that a large number of lighting devices are deployed in a wide space, it is necessary to transfer information to respective lighting devices at an accurate time in order to control the lighting devices.
In particular, in order for the lighting devices to operate accurately in such a transfer method, a technology is necessary, which enables a plurality of lighting devices to operate simultaneously. In particular, in order to control lighting devices so that a very large number of lighting devices, for example, several tens or hundreds of thousands of lighting devices, operate without any temporal difference, close operations among the lighting devices and a control device and their preprocessing are necessary.
An aspect of the present disclosure is to prevent an omission of a message for controlling lighting devices in a space where a plurality of lighting devices are distributed and to finely control the operation timing among the plurality of lighting devices.
Another aspect of the present disclosure is to effectively control a plurality of lighting devices using light output patterns pre-stored in the lighting devices in accordance with a low-capacity control message.
In accordance with an embodiment of the present disclosure, a lighting device includes: a light source unit; a first communication unit configured to receive library data from a mobile terminal; a storage unit configured to store the library data; a second communication unit configured to receive a control message indicating an execution command of a library corresponding to the library data from a control device; and a processor configured to control the light source unit to execute the library in accordance with the control message, wherein the processor is configured to control an operation timing of the light source unit by sequentially receiving the control message over a predetermined number of times at an initial execution of the library.
In accordance with an embodiment of the present disclosure, a performance system includes: a control device configured to generate a control message indicating an execution command of a library; a transmission device configured to transmit the generated control message; a plurality of repeaters configured to transfer the control message, received from the transmission device, in a broadcasting method; and a plurality of lighting devices configured to store library data corresponding to the library and to execute the library using the stored library data in accordance with the control message received from the repeaters, wherein each of the plurality of lighting devices is configured to control an operation timing of a light source unit by sequentially receiving the control message over a predetermined number of times at an initial execution of the library.
According to various embodiments of the present disclosure, even if a plurality of lighting devices are distributed, such that the message is omitted, the operations of the plurality of lighting devices can be synchronized without time delay.
Further, according to various embodiments of the present disclosure, because the lighting device stores predetermined light output patterns, the control device can transmit a small-capacity message to the lighting device, and thus the message transfer can be efficiently performed.
Hereinafter, embodiments related to the present disclosure will be described in more detail with reference to the accompanying drawings. In the following description, suffixes “ . . . module” and “ . . . unit” for constituent elements, as used herein, are given or are interchangeably used in consideration of only easiness in preparing the description, but do not have mutually distinctive meanings or roles.

The group information may be configured by a user in a QR code tagging method through a ticket number or a ticket seat number using an application installed in the mobile terminal 60.
After configuring the group information, the mobile terminal 60 transmits the scenario data to the lighting device 50 (S809).

The plurality of lighting devices 50-1 to 50-n control the operations of the light source units 56, respectively, in accordance with the received control message (S909).
Next, a scenario and data constituting the scenario according to an embodiment of the present disclosure will be described.
One scenario 1000 may include a plurality of libraries 1010, 1020, 1030, 1040, and 1050.
A scenario promoter may design the scenario by dividing the total playback interval of one song into a plurality of intervals through the control device 20 or the central server 5.
It is assumed that the total playback time of one song is four minutes.
The plurality of intervals may correspond to the plurality of libraries 1010 to 1050, respectively.
A first library 1010 may indicate that the light source units 56 of all the lighting devices should be turned off for 10 seconds from a start of a song.
A second library 1020 may indicate that the light source units 56 of all the lighting devices should be turned on for 20 seconds after performing the first library 1010.
A third library 1030 may indicate that the light source units 56 of all the lighting devices should perform strobe operations for one minute after performing the second library 1020.

Referring to
The scenario 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 on a color table capable of expressing 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.
The library data to be described later may include the index values included in the color table.
Each of the plurality of library fields 1130-1 to 1130-n may include a library header and a library data.
For example, a 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 the first library 1010 of
Each library data may include information on one or more of group identification information, library identification information, a lighting group operation start time, a lighting group operation end time, color information that should be output by the lighting group, and a pattern that should be output by the lighting group.
Information contained in each library data will be described in detail with reference to
Referring to
Group identification information is information for identifying that a plurality of lighting devices deployed in a space are divided into n groups, and the respective lighting groups perform different operations.
The group identification information may be used as information for identifying the lighting group described above with reference to
If the group identification information is “ALL”, it may indicate that all the lighting groups perform the same library.
The library identification information is information that is included in case that the control device 20 commands the respective lighting devices to operate in accordance with a specific library.
For example, if the control device 20 transmits a control message “library 002 operation”, the lighting device executes “002” among the library identification information.
In case that the lighting devices are divided into the plurality of groups, the lighting device 50 may operate in accordance with the configured group number.
For example, in the same manner, if the lighting device 50 belonging to a first lighting group GROUP1 and receives the command message “library 002 operation” from the control device 20, the lighting device 50 may perform a corresponding pattern “R/GRAD_10/B/Repeat 60”.
Further, if the lighting device 50 belonging to a second lighting group GROUP2 and receives the command message “library 002 operation” from the control device 20, the lighting device 50 may perform a corresponding pattern “B/GRAD_30/G/Repeat 60”.
Further, if the lighting device 50 belonging to a third lighting group GROUPS and receives the command message “library 002 operation” from the control device 20, the lighting device 50 may perform a corresponding pattern “G/GRAD_30/R/Repeat 60”.
“StartTime” may indicate information corresponding to a time when the library is performed.
If the StartTime is “NULL”, it means that the corresponding library operates in accordance with an indication of the control message of the control device 20.
The pattern may indicate a color of light emitted by the light source unit 56, a light emitting time, a repetition period, or a blinking or turn-off period. R, G, and B indicate red, green, and blue, respectively.
In case that the light source unit 56 can adjust light more precisely, the light source unit 56 may output colors obtained by combining the R, G, and B. In case of indication with RGB 256 colors, 1 byte (8 bits) may be defined for each of the R, G, and B, and in defining the RGB, 3 bytes may be required in displaying the RGB.
The color of light output by the light source unit 56 may be configured in various types, such as, RGB, R/G/B, or specific binary number or hexadecimal number.
Further, the light source on/off and the holding time (second) may be recorded together. Further, the number of repetitions or repetition time may be configured as REPEAT.
“GRAD” means that light output by the light source unit 56 has a pattern that light is gradually changed in gradation. In an embodiment, the library “002” of the first lighting group is “R/GRAD_10/B/REPEAT_60”, and this means that the color of the light output by the lighting device 50 is changed from red to blue in gradation for 10 seconds and such a change is repeated 60 times (or repeated for 60 seconds). “BLINK” indicates blinking.
Further, although not illustrated in
The control message may be transmitted to the lighting device 50 through a repeater 40 in a broadcasting method. In case of using a unicast method rather than the broadcasting method, the transmission device 30 needs to receive an ack message corresponding to the reception of the transmitted control message from the lighting device 50. In this case, if the ack message is received from a large number of lighting devices, a communication situation may deteriorate.
Accordingly, in an embodiment of the present disclosure, the transmission device 30 transmits the control message to the lighting device 50 in the broadcasting method.
Referring to
The transmission device 30 may sequentially transmit 0-th to fourth control messages 1301 to 1305 to the lighting device 50.
The 0-th to fourth control messages 1301 to 1305 may be sequentially transmitted to the lighting device 50 in a predetermined period.
Each of the 0-th to fourth control messages 1301 to 1305 may include the same library identification information. However, the respective control messages may have different sequence numbers.
For example, when the 0-th to fourth control messages 1301 to 1305 are sequentially transmitted, the sequence number may be increased by 1.
The sequence number may indicate a transmission interval between the sequentially transmitted control messages. The transmission interval of the respective control messages may be 0.4 second, but this is merely an example.
The reason why the five control messages 1301 to 1305 are sequentially transmitted is to control even a fine timing difference among the respective lighting groups or the lighting devices in the lighting groups in a situation that the transmission of the control message may be omitted depending on the communication situation.
The omission of the transmission of the control message may indicate that the lighting device 50 is unable to receive the control message.
Referring to
If it is assumed that the execution time of one library is 3 seconds, the lighting device 50 does not output blue and green (refer to 1303 and 1305), but outputs red gradually stronger for 1 second, and then maintains the output for the remaining 2 seconds (1301).
The initial 0.5 second period will be enlarged for explanation.
A first red pattern graph 1331 shows that the first lighting device gradually increases and outputs a red light in accordance with the 0-th control message 1301 in case that the first lighting device receives the 0-th control message 1301.
A second red pattern graph 1333 shows that the second lighting device gradually increases and outputs the red light in accordance with the second control message 1303 in case that the second lighting device is unable to receive the 0-th control message 1301 and the first control message 1302.
A third red pattern graph 1335 shows that the third lighting device gradually increases and outputs the red light in accordance with the third control message 1304 in case that the third lighting device is unable to receive the 0-th to second control messages 1301 to 1303.
The time when the five control messages 1301 to 1305 are sequentially transmitted is very short, and for this reason, even if some light devices are unable to receive the initial control message, the lighting devices may immediately perform the library through reception of the following control messages.
Further, the five control messages 1301 to 1305 may include sequence numbers indicating transmission intervals. The lighting device 50 having not received the initial some control messages may control the execution timing of the library using the sequence number included in the control message.
In accordance with the sequence number, the fine time difference between operations of the respective lighting devices 50 can be controlled.
In
Further, it is assumed that a bundle of the 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
After transmitting the retransmission packet 1400, the transmission device 30 may transmit a sync packet 1410 to the respective lighting devices in each predetermined period. Further, the sync packet may be a packet for checking whether the respective lighting devices 50 well follow the execution of the library.
The sync packet may include information on one time point of a library and information on a pattern that should be performed at the corresponding one time point in order to match the operation synchronization among the respective lighting devices 50.
As illustrated in
As illustrated in
As described above, according to an embodiment of the present disclosure, even in case that the lighting device 50 is unable to receive the control message for executing the library, the lighting device 50 can immediately execute the library by means of the sync packet, and thus can effectively match the synchronization with other lighting devices.
Next, an operation mode of a lighting device will be described.
Hereinafter, it is assumed that operation 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 like 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 capable of turning on/off an output of the light source unit 56 without communication with an external device.
Referring to
After 5 seconds, the operation mode of the lighting device 50 may be switched from the RF mode 1510 to the BLE mode 1530. Again, after 25 seconds, the operation mode of the lighting device 50 may be switched from the BLE mode 1530 to the RF mode 1510.
If the lighting device 50 is unable to receive a heartbeat MSG message from the repeater being BLE-connected with the mobile terminal 60 while such a cycle is repeated n times, the operation mode of the lighting device 50 may be switched to the standalone mode 1550.
The reason why the operation mode of the lighting device 50 is changed in a power initialization process is to determine whether it is possible to take part in a performance by changing the operation mode because it is impossible to simultaneously use an RF protocol in case of using multiple RF stacks.
Next,
Referring to
In an embodiment, the lighting device 50 may receive the performance preparation message from the repeater 40 through the control device 20.
The performance preparation message may be a message for blocking the switchover to the standalone mode. In case that a user enters a performance hall and performs an operation separately from a library, by operating the lighting device 50 in the standalone mode, direction through the lighting devices may not be properly performed.
For this, the performance preparation message may be transmitted to the respective lighting devices 50 to prevent a user from arbitrarily controlling the lighting devices 50.
In accordance with the reception of the performance preparation message, the lighting device 50 blocks the switchover to the standalone mode (S1603).
In an embodiment, the lighting device 50 may be switched from the RF mode to the BLE mode in accordance with the reception of the performance preparation message. This is because a situation may occur, in which the lighting device 50 should receive the library data or the scenario data from the mobile terminal 60.
The lighting device 50 determines whether the performance type is an integrated direction based on a performance identifier included in the performance preparation message (S1605).
In an embodiment, if the performance type is the integrated direction, all the lighting devices may be collectively controlled under the control of the control device 20. In this case, it is not necessary for the lighting device 50 to store the library data. This is because the message transmitted by the control device 20 may include detailed operation contents (light output on or off) of the lighting device 50.
If the performance type is the integrated direction, the lighting device 50 operates in the RF mode (S1607).
Accordingly, the lighting device 50 prepares to receive the control message from the control device 20.
If the performance type is an individual direction, the lighting device 50 determines whether a concert identifier included in the performance preparation message is stored (S1609).
If the performance type is the individual direction, the lighting device 50 may 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 the RF mode (S1607).
If the concert identifier is not stored in the performance preparation message, the lighting device 50 acquires the library data including the corresponding concert identifier from the mobile terminal 60 (S1611).
That is, according to the embodiment of
Next, an operation of the lighting device 50 depending on whether the lighting device 50 and a cradle capable of mounting the lighting device 50 are docked with each other will be described.
A cradle 1700 may be a device capable of supplying power, provided from outside, to the lighting device 50 in case that the lighting device 50 is mounted on the cradle 1700.
Referring to
Referring to
The four cheer modes may correspond to a plurality of buttons 58a to 58d provided on the lighting device 50, respectively.
If any one of the plurality of buttons 58a to 58d is selected, the lighting device 50 may control the operation of the light source unit 56 so as to operate in the cheer mode corresponding to the selected button.
Next, an operation of the lighting device 50 in case that the lighting device 50 and the cradle 1700 are docked with each other will be described.
In particular,
In case that 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 thereto (S1801).
Thereafter, the lighting device 50 may activate the BLE mode (specifically, beacon mode), and may transmit a beacon signal to outside in a broadcasting method using an AltBeacon protocol (S1803).
Referring to
In case that the lighting device 50 is connected to the mobile terminal 60, the lighting device 50 may output light indicating a welcome sign (S1807).
In case that the mobile terminal 60 is connected to the lighting device 50, the mobile terminal 60 may transmit a command for outputting the light indicating the welcome sign to the lighting device 50.
Thereafter, the lighting device 50 waits for deviation from a beacon signal recognition range (S1809), that is, the lighting device 50 recognizes that the mobile terminal 60 does not exist therearound, and if the mobile terminal 60 does not exist therearound, the lighting device 50 waits for a predetermined time (S1811).
