Lighting control system and lighting control method thereof
First Claim
1. A lighting device comprising:
- a lighting unit;
a communication interface configured to receive a control signal generated at an external device directly from the external device or by way of another lighting device in a network of a plurality of lighting devices comprising the lighting device and the other lighting device, depending on a connection relationship between the plurality of lighting devices;
a memory configured to store information about the lighting device; and
a controller configured to, according to the control signal and the information about the lighting device, selectively perform one of directly controlling an operation of the lighting unit and transmitting the control signal to the network through the communication interface so that the control signal is relayed to at least one other lighting device in the network through the communication interface for the external device to indirectly control an operation of at least one target lighting device included in the network by way of the lighting device.

Abstract
A lighting device included in a network of a plurality of lighting devices includes: a lighting unit; a communication interface configured to receive a control signal generated at an external device directly from the external device or by way of another lighting device in the network, depending on a connection relationship between the plurality of lighting devices; a memory configured to store information about the lighting device; and a controller configured to, according to the control signal and the information about the lighting device, selectively perform one of controlling an operation of the lighting unit and relaying the control signal to at least one other lighting device in the network through the communication interface to control an operation of at least one target lighting device included in the network. Here, the at least one other lighting device itself may be the at least one target lighting device.

12. A method of controlling at least one lighting device in a network comprising a plurality of lighting devices, the method comprising:
-
receiving, at a lighting device included in the network, a control signal generated at an external device directly from the external device or by way of another lighting device included in the network, depending on a connection relationship between the plurality of lighting devices; storing information about the lighting device in a memory of the lighting device; and according to the control signal and the information about the lighting device, selectively performing one of directly controlling an operation of the lighting unit and transmitting the control signal to the network so that the control signal is relayed to at least one other lighting device in the network for the external device to indirectly control an operation of at least one target lighting device included in the network by way of the lighting device. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20, 21, 22)

23. A non-transitory computer readable medium having recorded thereon instructions executable by a processor of an external device to perform a method comprising:
-
searching for a lighting device in a network comprising a plurality of lighting devices which is to be connected to the external device; generating a control signal which selectively controls one of an operation of the lighting device and an operation of at least one target lighting device connected to the lighting device in the network; and transmitting the control signal directly to the lighting device, wherein, in response to the control signal indicating that the control signal is directed to the lighting device, the operation of the lighting device is directly controlled, and wherein, in response to the control signal indicating that the control signal is directed to the at least one target lighting device, the control signal is transmitted to the network so that the control signal is relayed to the at least one other lighting device in the network for the external device to indirectly control the operation of the at least one target lighting device by way of the lighting device. - View Dependent Claims (24, 25, 26, 27)
