Abstract

Disclosed are a lighting control system including and mater and slave devices. The master device includes a lighting control unit that broadcasts a group light-emitting pattern to each corresponding group of the plurality of slave devices to control the plurality of slave devices to emit the light per group basis. Each of the plurality of slave devices includes a lighting unit configured to include at least one light source device, a storing unit configured to store the light-emitting position information corresponding, and a lighting control unit configured to extract a lighting control signal of the group identification number corresponding to the light-emitting position information stored in the storing unit among lighting control signals broadcasted by the master device, and control the lighting unit on the basis of the group light-emitting pattern corresponding to the extracted lighting control signal.

Claims

1. A lighting control system for directing a show comprising:

a plurality of slave devices corresponding to in each seat of a plurality of audiences in an auditorium; and

a master device configured to broadcast a lighting control signal to control the plurality of slave devices to emit a light,

wherein the master device comprises;

a lighting control unit configured to

receives a group identification number, a light-emitting position information including information that is previously set to classify the plurality of slave devices into a plurality of groups, and information indicating specific positions at which the slave devices corresponding to a previously-set electrical code information to emit the light, and

broadcast a group light-emitting pattern to each corresponding group of the plurality of slave devices to control the plurality of slave devices to emit the light per group basis, and

wherein each of the plurality of slave devices comprises;

a lighting unit configured to include at least one light source device;

a storing unit configured to store the light-emitting position information corresponding; and

a lighting control unit configured to

extract a lighting control signal of the group identification number corresponding to the light-emitting position information stored in the storing unit among lighting control signals broadcasted by the master device, and

control the lighting unit on the basis of the group light-emitting pattern corresponding to the extracted lighting control signal.

2. The lighting control system according to claim 1, further comprising:

an information check unit configured to obtain a seat position of a first slave device from electrical code information of a ticket and to obtain light-emitting position information corresponding to the obtained seat position.

3. The lighting control system according to claim 1, wherein each of the plurality of slave devices is configured to control the lighting unit by periods previously determined on the basis of the received lighting control signal.

4. The lighting control system according to claim 2, wherein the lighting control unit is configured to provide directing information to the first slave device, and the directing information is information to control the first slave device such that the lighting unit of the first slave device to emit the light by one or more predetermined periods, and the directing information is activated when the first slave device receives the lighting control signal.

5. The lighting control system according to claim 4, wherein the lighting control unit of the master device is configured to transmit a lock signal to the plurality of slave devices to drive the first slave device in a lock mode during a predetermined period.

6. The lighting control system according to claim 4, further comprises:

a storing unit configured to store the light-emitting position information corresponding to previously-set electrical code information and the directing information.

7. The lighting control system according to claim 4, wherein the light-emitting position information and the directing information are set previously or in real time.
