| Claim: | 1. An illumination apparatus, comprising: a plurality of light sources including LEDs generating radiation of different spectra combinable to produce white light, each light source being independently addressable over a wireless communication network and comprising an LED; and an associated controller controlling a parameter of the radiation generated by the LED, based at least in part on a lighting control signal received by the controller over the wireless communication network, so as to control at least a color temperature of the white light. |
| Claim: | 2. The apparatus of claim 1 , wherein the wireless communication network supports at least one of a radio frequency transmission, an infrared transmission, a microwave transmission, and an acoustic transmission. |
| Claim: | 3. The apparatus of claim 2 , wherein the wireless communication network supports the radio frequency transmission, and wherein the apparatus further comprises a radio transceiver coupled to the controller to receive the lighting control signal. |
| Claim: | 4. The apparatus of claim 1 , wherein the controller varies a color temperature of the white light based at least in part on the lighting control signal. |
| Claim: | 5. The apparatus of claim 1 , wherein the lighting control signal includes information for identifying the light sources over the wireless communication network. |
| Claim: | 6. The apparatus of claim 4 , further comprising a memory storing a lighting program, wherein the controller modifies a variable of the lighting program based on the lighting control signal, and executes the lighting program to control the color temperature of the white light. |
| Claim: | 7. The apparatus of claim 4 , further comprising a memory storing a plurality of lighting programs, wherein the controller selects one of the lighting programs based on the lighting control signal, and executes the selected lighting program to control the color temperature of the white light. |
| Claim: | 8. The apparatus of claim 7 , wherein the controller modifies a variable of the selected lighting program based on the lighting control signal. |
| Claim: | 9. A system including the apparatus of claim 2 , the system further comprising a user interface coupled to the wireless communication network, the user interface generating the lighting control signal based on user operation of the user interface. |
| Claim: | 10. The system of claim 9 , wherein the user interface comprises at least one of a dial a button, a switch, a slider, a variable switch, and a variable selector. |
| Claim: | 11. A method, comprising: generating radiation of different spectra with light sources independently addressable over a wireless communication network, the different spectra being combinable to produce white light, and the light sources comprising an LED and an associated controller; and controlling a parameter of the radiation by the associated controller, based at least in part on a lighting control signal received over the wireless communication network, so as to control at least a color temperature of the white light. |
| Claim: | 12. The method of claim 11 , wherein the wireless communication network supports at least one of a radio frequency transmission, an infrared transmission, a microwave transmission, and an acoustic transmission. |
| Claim: | 13. The method of claim 12 , wherein the wireless communication network supports the radio frequency transmission, and wherein the method further comprises: receiving the lighting control signal via the radio frequency transmission. |
| Claim: | 14. The method of claim 11 , wherein controlling the parameter of the radiation comprises: varying a color temperature of the white light based at least in part on the lighting control signal. |
| Claim: | 15. The method of claim 11 , wherein controlling the parameter of the radiation comprises: controlling the parameter based at least in part on identification information included in the lighting control signal, the identification information identifying the light sources over the wireless communication network. |
| Claim: | 16. The method of claim 11 , wherein controlling the parameter of the radiation comprises executing a lighting program to control the parameter. |
| Claim: | 17. The method of claim 16 , wherein controlling the parameter of the radiation further comprises: modifying a variable of the lighting program based on the lighting control signal. |
| Claim: | 18. The method of claim 11 , wherein controlling the parameter of the radiation comprises: selecting one of a plurality of lighting programs based on the lighting control signal; and executing the selected lighting program to control the parameter. |
| Claim: | 19. The method of claim 18 , wherein controlling the parameter of the radiation further comprises: modifying a variable of the selected lighting program based on the lighting control signal. |
| Claim: | 20. The method of claim 11 , further comprising: generating the lighting control signal by operating a user interface coupled to the wireless communication network. |
| Claim: | 21. The method of claim 20 , wherein the user interface comprises at least one of a dial a button, a switch, a slider, a variable switch, and a variable selector. |
