The lighting control apparatus makes communication with lighting devices, registers at least one of the lighting devices according to received signal strengths of the lighting devices, and controls the registered lighting device. The lighting control apparatus easily registers and controls the lighting devices. ## Claims ### Claim 1 A lighting control system comprising: lighting devices; and a lighting control apparatus for registering at least one of the lighting devices and for controlling the registered lighting device; wherein the lighting control apparatus registers at least one of the lighting devices as a reference lighting device and registers at least one of other lighting devices by using the reference lighting device; wherein the reference lighting device transmits a peripheral search signal to the other lighting devices according to a command of the lighting control apparatus, receives a response message corresponding to the peripheral search signal from at least one of the other lighting devices, and notifies the response message to the lighting control apparatus; wherein each lighting device has intrinsic identification data; and wherein the at least one of the other lighting devices transmits the response message including the intrinsic identification according to the peripheral search signal. ### Claim 2 (depends on 1) The lighting control system of claim 1, wherein the lighting control apparatus displays a display screen image including a switch to turn on/off the registered lighting device and a control unit to control a dimming operation of the registered lighting device, and controls the registered lighting device by detecting a command according to the switch or the control unit. ### Claim 3 (depends on 1) The lighting control system of claim 1, wherein the response message includes the received signal strength measured from the peripheral search signal by at least one of the other lighting devices, wherein the lighting control apparatus registers the at least one of other lighting devices according to the received signal strengths between the reference lighting device and the other lighting devices. ### Claim 4 (depends on 3) The lighting control system of claim 3, wherein the reference lighting device measures the received signal strength from the response message. ### Claim 5 (depends on 3) The lighting control system of claim 3, wherein the lighting control apparatus registers at least one of the other lighting devices if the received signal strength exceeds a previously-stored received signal strength. ### Claim 6 (depends on 1) The lighting control system of claim 1, wherein the lighting control apparatus selects one of the lighting devices, transmits a registration request signal to the selected lighting device, receives a response message corresponding to the registration request signal from the selected lighting device, and registers the selected lighting device. ### Claim 7 (depends on 6) The lighting control system of claim 6, wherein the lighting control apparatus displays a display screen image including a registration request key and an input window, transmits the registration request signal if the registration request key is selected, and registers identification data corresponding to at least one of the lighting devices if the identification data is input into the input window. ### Claim 8 A lighting control method comprising: registering at least one of lighting devices by a lighting control apparatus; and controlling the registered lighting device by the lighting control apparatus, and wherein the registering at least one of the lighting devices comprises: registering one of the lighting devices as a reference lighting device by the lighting control apparatus; transmitting a peripheral search signal to the other lighting devices according to a command of the lighting control apparatus, by the reference lighting device; receiving a response message corresponding to the peripheral search signal from at least one of the other lighting devices, by the reference lighting device; transmitting the response message to the lighting control apparatus, by the reference lighting device; and registering at least one of the other lighting devices using the response message, by the lighting control apparatus. ### Claim 9 (depends on 8) The lighting control method of claim 8, wherein the controlling the registered lighting device comprises: displaying a display screen image including a switch to turn on/off the registered lighting device and a control unit to control a dimming operation of the registered lighting device by the lighting control apparatus; and controlling the registered lighting device by detecting a command according to the switch or the control unit, by the lighting control apparatus. ### Claim 10 (depends on 8) The lighting control method of claim 8, wherein the at least one of the other lighting devices transmits the response message including the intrinsic identification according to the peripheral search signal. ### Claim 11 (depends on 10) The lighting control method of claim 10, wherein the registering at least one of the other lighting devices comprises registering at least one of other lighting device according to received signal strengths between the reference lighting device and the other lighting devices, by the lighting control apparatus. ### Claim 12 (depends on 10) The lighting control method of claim 10, wherein the transmitting of the response message comprises: measuring the received signal strength of the response message by the reference lighting apparatus. ### Claim 13 (depends on 8) The lighting control method of claim 8, wherein the registering at least one of the lighting devices further comprises: selecting one of the lighting devices by the lighting control apparatus; transmitting a registration request signal to the selected lighting device, by the lighting control apparatus; receiving a response message corresponding to the registration request signal from the selected lighting device, by the lighting control apparatus; and registering the selected lighting device by the lighting control apparatus. ### Claim 14 (depends on 13) The lighting control method of claim 13, wherein the registering at least one of the lighting devices further comprises: displaying a display screen image including a registration request key and an input window by the lighting control apparatus; transmitting the registration request signal by the lighting control apparatus if the registration request key is selected; and registering identification data corresponding to at least one of the lighting devices by the lighting control apparatus if the identification data is input into the input window.
