Abstract

A lighting control system for multiple lighting loads includes a computer that displays a pictograph and a lighting control panel. The pictograph includes selectable representations of the lighting loads. A particular lighting load is controlled by selecting a lighting state such as "on" or "off" on the lighting control panel and selecting a representation of the particular lighting load on the pictograph.

Claims

1. A computer for controlling a plurality of lighting loads, the computer comprising:

a display; and

memory encoded with executable instructions, the instructions, when executed, causing the computer to show a pictograph and a control panel on the display, the pictograph including selectable representations of the lighting loads, the control panel allowing a lighting load state to be entered into the computer, the instructions further causing the computer to generate a lighting control request when a representation on the pictograph is selected, the lighting control request identifying a lighting load corresponding to the selected representation, the lighting control request further identifying the lighting control state entered into the computer, and send the lighting control request to a computer network, whereby the lighting control request is used for controlling the lighting load corresponding to the selected representation.

2. The computer of claim 1, further comprising means for connecting to a computer network, the instructions further instructing the computer to send the lighting control request to the computer network.

3. The computer of claim 1, wherein the instructions are included in a web browser program and an HTML file, the web browser program and the HTML file causing the computer to download and display a pictograph-based image map including the selectable representations, the web browser program and the HTML file also causing the computer to download and display an HTML lighting control form for allowing the lighting load state to be entered into the computer.

4. The computer of claim 1, wherein the lighting control form includes a plurality of graphical display elements for entering the lighting load states into the computer.

5. The computer of claim 2, wherein the web browser program and the HTML file instructions cause the computer to generate the lighting control request including coordinates of the selected representation and the lighting state entered into the computer when a representation on the image map is selected.

6. The computer of claim 1, wherein the instructions are included in a web browser program, an HTML file and an applet, the web browser program, the HTML file and the applet causing the computer to download and display the pictograph and display a control panel for allowing the lighting load state to be entered into the computer.

7. The computer of claim 6, wherein the lighting control panel includes a plurality of graphical display elements for entering the lighting load states into the computer.

8. The computer of claim 6, wherein the web browser program, the HTML file and the applet cause the computer to generate the lighting control request including an identification of a lighting load and the lighting state entered into the computer.

9. The computer of claim 1, wherein the pictograph includes a clickable floor plan.

10. The computer of claim 9, wherein the pictograph is link,able to other clickable floor plans.

11. The apparatus of claim 1, further comprising an interface module adapted to be coupled to a power/communications bus;

and wherein the instructions further instruct the computer to translate the lighting control requests into digital commands for the interface module, the digital commands indicating the identified lighting load and the lighting state of the identified lighting load.

12. A method of controlling a plurality of lighting loads using a computer connectable to a computer network, the method comprising:

displaying a pictograph including a plurality of selectable representations of the lighting loads on the computer;

displaying a control panel on the computer, the control panel allowing a lighting load state to be entered into the computer;

generating a lighting control request when a lighting load state is entered into the computer and a selectable representation on the pictograph is selected; and

sending the lighting control request to the computer network whereby the lighting control request is used for controlling the lighting load corresponding to the selected representation.

13. The method of claim 12, wherein the lighting control requests are sent to the network using a TCP/IP protocol.

14. The method of claim 12, wherein the lighting control requests include coordinates of the selected representation and the lighting load state.

15. The method of claim 12, wherein the lighting control requests include a lighting load identifier and the lighting load state.

16. An article of manufacture for a computer, the article comprising:

computer memory; and

a plurality of executable instruction encoded in the memory, the instructions, when executed, causing the computer to display a pictograph and a control panel, the pictograph including selectable representations of the lighting loads, the control panel allowing a lighting load state to be entered into the computer, the instructions further causing the computer to generate a lighting control request when a representation on the pictograph is selected, the lighting control request identifying a lighting load corresponding to the selected representation, the lighting control request further identifying the lighting control state entered into the computer and send the lighting control request to a computer network, whereby the lighting control request is used for controlling the lighting load corresponding to the selected representation.

17. The article of claim 16, wherein the instructions are included in a web browser program and an HTML file, the web browser program and the HTML file causing the computer to download and display an image map including the selectable representations, the web browser program and the HTML file also causing the computer to download and display an HTML lighting control form for allowing the lighting load state to be entered into the computer.

18. The article of claim 17, wherein the web browser program and the HTML file instructions cause the computer to generate the lighting control request including coordinates of the selected representation and the lighting state entered into the computer when a representation on the image map is selected.

19. The article of claim 16, wherein the instructions are included in a web browser program, an HTML file and an applet, the web browser program, the HTML file and the applet causing the computer to download and display the pictograph and display a control panel for allowing the lighting load state to be entered into the computer.

20. The article of claim 19, wherein the web browser program, the HTML file and the applet cause the computer to generate the lighting control request including an identification of a lighting load and the lighting state entered into the computer when a representation on the pictograph is selected.

21. The article of claim 16, wherein the pictograph includes a clickable floor plan.

22. The article of claim 21, wherein the pictograph is linkable to other clickable floor plans.
