Abstract

A lighting control system as disclosed herein may include a plurality of lighting apparatuses provided in a building, a display for displaying an image representing the plurality of lighting apparatuses, an input interface for selecting at least one region on the image that corresponds to one or more of the plurality of lighting apparatuses, a memory for storing the defined region of the image, and a controller configured to control the lighting apparatuses. One or more control groups may be configured based on the selected region and the image may be updated to display the control groups.

Claims

1. A lighting control system comprising:

a display configured to display floor plan of a lighting space having a plurality of light emitting units mounted thereto and display a grid for a reference coordinate system on the floor plan to divide the floor plan into a plurality of control groups using the grid on the floor plan, wherein the grid is displayed at prescribed intervals throughout the floor plan and does not have a one-to-one relationship with the light emitting units, at least a portion of the grid being displayed at a location on the floor plan without a corresponding light emitting unit;

an input interface for selecting a particular region of the floor plan displayed by selecting reference coordinates of the grid;

a memory for storing group information on an area of the floor plan fixed with the particular reference coordinates, and group information on the light emitting units mounted to the area of the floor plan; and

a controller for integrating and storing the group information stored in advance, the group information on the particular region, and the group information on the light emitting units mounted to the particular region when the group information on the particular region selected is changed.

2. The lighting control system of claim 1, wherein the grid includes a plurality of points spaced at predetermined intervals in at least one of horizontal and vertical directions on a rectangular coordinate system.

3. The lighting control system of claim 2, wherein the controller activates a particular lighting space fixed by connecting the plurality of points on the grid selected by a user on the display.

4. The lighting control system of claim 3, wherein the controller stores the lighting space activated according to user'"'"'s input as a new control group, or removes the lighting space from the control group and wherein the controller integrates the new control group and an existing control group, and stores the same together with the drawing information.

5. The lighting control system of claim 3, wherein if two or more than two lighting spaces are activated according to user'"'"'s input, the controller merges the lighting spaces into a control group, or divides the lighting space into two control groups.

6. The lighting control system of claim 1, wherein coordinate values for a point selected on the grid is displayed adjacent to the displayed floor plan.

7. A lighting control system comprising:

a display including a first region for displaying a floor plan of a lighting space having a plurality of light emitting units mounted thereto and display a grid for a reference coordinate system on the floor plan to divide the floor plan into a plurality of control groups using the grid on the floor plan, wherein the grid is displayed at prescribed intervals throughout the floor plan and does not have a one-to-one relationship with the light emitting units, at least a portion of the grid being displayed at a location on the floor plan without a corresponding light emitting unit, and a second region having an input interface displayed thereon for selecting a particular region of the floor plan displayed by selecting reference coordinates of the grid; and

a controller for storing group information on an area of the lighting space defined with the particular reference coordinates and list information on the light emitting units mounted to the portion of the lighting space, and, if control group information on the particular region selected is changed, integrating and storing control group information stored in advance, control group information on the particular region, and the list information on the light emitting units mounted to the particular region.

8. The lighting control system of claim 7, wherein the input interface includes

a first input unit for storing or removing the control groups,

a second input unit for merging or dividing the control groups, and

a third input unit for selecting a particular lighting space.

9. The lighting control system of claim 8, wherein the controller activates the particular lighting space fixed by connecting a plurality of coordinates on the displayed grid selected by the user on the first display region.

10. The lighting control system of claim 9, wherein if the first input unit is selected, the controller stores a relevant lighting space as a new control group, or removes the relevant lighting space from the control group.

11. The lighting control system of claim 9, wherein if the second input unit is selected, the controller merges two or more than two lighting spaces activated thus as a new control group, or divides the two or more than two lighting spaces activated thus into new control groups respectively.

12. The lighting control system of claim 11, wherein the controller integrates new control groups and existing control groups and stores the same together with the drawing information.

13. The lighting control system of claim 7, wherein the controller outputs control group numbers respectively matched to the lighting spaces to the drawing information.

14. The lighting control system of claim 7, wherein coordinate values for a point selected on the grid is displayed adjacent to the displayed floor plan.

15. A lighting system comprising:

a plurality of light emitting units mounted to a lighting space;

at least one bridge device connected to the plurality of light emitting units to enable communication therewith;

a gateway connected to the bridge device to enable communication therewith;

a central controller including a lighting controller connected to the gateway to enable communication therewith, and having a list of addresses of the light emitting units stored therein, and a monitoring panel connected to the lighting controller to enable communication therewith for transmission of setting information and control information on the light emitting units to the lighting controller; and

an interface connected to the lighting controller to enable communication therewith for application of a control order or displaying an operation state,

wherein the monitoring panel includes;

a display including,

a first region for displaying a floor plan of a lighting space having a plurality of light emitting units mounted thereto and display a grid for a reference coordinate system on the floor plan to divide the floor plan into a plurality of control groups using the grid on the floor plan, wherein the grid is displayed at prescribed intervals throughout the floor plan and does not have a one-to-one relationship with the light emitting units, at least a portion of the grid being displayed at a location on the floor plan without a corresponding light emitting unit, and a second region having an input unit displayed thereon for selecting a particular region of the image displayed by selecting reference coordinates of the grid, and

a controller for storing group information on an area of the lighting space fixed with the particular reference coordinates and list information on the light emitting units mounted to the portion of the lighting space, and, if control group information on the particular region selected is changed, integrating and storing the control group information stored in advance, the control group information on the particular region, and the list information on the light emitting units mounted to the particular region.

16. The lighting system of claim 15, wherein the controller integrates new control groups and existing control groups, and stores the same together with the drawing information.

17. The lighting system of claim 15, wherein if there is a change of the control group, the controller can change the list of addresses of the light emitting units mounted to the lighting space together with the change.

18. The lighting system of claim 17, wherein the controller receives the list of addresses of the light emitting units from the lighting controller.

19. The lighting system of claim 16, wherein the controller transmits the drawing information having the control group changed thus to the interface through the lighting controller.

20. The lighting system of claim 15, wherein coordinate values for a point selected on the grid is displayed adjacent to the displayed floor plan.
