Abstract

A local computer generates requests for a remote computer to control a remotely-located lighting load. The local computer generates and displays a control panel, which prompts a user to enter an intensity for the remotely located lighting load. When an intensity is entered into the computer, the computer generates a lighting control request and sends the lighting control request to the remote computer. The remote computer controls power to the remotely-located lighting load according to the lighting control request.

Claims

1. Apparatus for requesting a remote computer to control an assigned lighting load, the remote computer being connected to the assigned lighting load via an interface module, a power/communications bus and a relay, the apparatus comprising:

an input device; and

means for storing an identifier for the assigned lighting load and for generating a lighting control request in response to the input device, the lighting control request indicating the identifier for the assigned lighting load and a lighting state for the assigned lighting load;

the means sending the lighting control request to the remote computer, whereby the remote computer controls power to the assigned lighting load in accordance with the indicated lighting state.

2. The apparatus of claim 1, further comprising a display, wherein the input device includes an I/O device, wherein the means includes a processor and computer memory encoded with a plurality of executable instructions, the instructions, when executed, instructing the processor to show a control panel on the display, the input means allowing the lighting load state to be entered into the control panel, the instructions further instructing the processor to generate the lighting control request when the lighting load state is entered and send the lighting control request to the remote computer.

3. The apparatus of claim 2, wherein the instructions further instruct the processor to show an icon on the display before showing the control panel, the control panel being shown when the icon is selected by the I/O device.

4. The apparatus of claim 1, wherein the input device includes a person detector;

and wherein the lighting control request is generated when a detection is made by the detector, whereby the apparatus functions as a smart sensor.

5. The apparatus of claim 1, wherein the input device includes a manual input device;

and wherein the means includes dedicated circuitry for generating the lighting control request in response to a manual input to the manual input device, the circuitry sending the lighting control request to the remote computer, whereby the apparatus functions as a smart appliance.

6. The apparatus of claim 1, wherein the remote computer is a server that is connected to a computer network, wherein the server includes a lighting daemon that listens for lighting control requests on the network;

and wherein the means communicates with the lighting control daemon by placing the lighting control request on the network.

7. The apparatus of claim 1, wherein the means receives the identifier from the remote computer.

8. The apparatus of claim 1, wherein the remote computer is a server that is connected to a network and that broadcasts messages over the network, the messages indicating status of different lighting loads;

and wherein the means receives the messages from the network and processes the messages to determine a lighting load status of the assigned lighting load.

9. Apparatus for requesting a computer to control an assigned lighting load, the apparatus comprising:

a display;

an I/O device;

a processor; and

computer memory encoded with a plurality of executable instructions, the instructions, when executed, instructing the processor to show on the display an icon that indicates status of the assigned lighting load, the processor being further instructed to show a control panel that prompts a user to enter a lighting load state via the I/O device, the processor further being instructed to generate a lighting control command when a lighting load state is entered via the I/O device and send the lighting control command to the computer.

10. The apparatus of claim 9, wherein the computer is a server that broadcasts messages indicating status of different lighting loads;

and wherein the instructions further instruct the processor to receive and process the messages and update the icon to indicate a change in status of the assigned lighting load.

11. An article of manufacture for a first computer including a display, an I/O device and network means for establishing communications with a second computer, the first computer being operable to request the second computer to control an assigned lighting load, the article of manufacture comprising:

computer memory; and

a plurality of executable instructions encoded in the memory, the instructions, when executed, instructing the first computer to show a control panel on the display, the control panel allowing a lighting load state to be entered via the I/O device, the first computer further being instructed to generate a lighting control request when the state is entered and send the lighting control request to the second computer via the network means, the lighting control request indicating an identifier for the assigned lighting load and the lighting load state entered via the I/O device.

12. The article of claim 11, wherein the instructions further instruct the first computer to determine the identifier from the second computer.

13. The article of claim 11, wherein the instructions further instruct the first computer to show a selectable icon on the display before showing the control panel, the control panel being shown when the icon is selected by the I/O device.

14. The article of claim 11, wherein the instructions further instruct the first computer to show an icon indicating the status of the lighting load;

and update the icon to indicate a change in status of the lighting load.
