Abstract

Provided herein are methods and systems for illuminating environments, including aircraft environments. The methods and systems include facilities for providing both white and non-white illumination, with color and color temperature control, in programmed response to inputs. Methods and systems are also provided for improving the addressing of light systems in a network lighting configuration.

Claims

1. A method, comprising:

controlling at least one light via a lighting control signal to provide illumination including at least one of a white color and a non-white color, the at least one light comprising at least one first LED configured to generate first radiation and at least one second LED configured to generate second radiation different from the first radiation; and

generating the lighting control signal based at least in part on data provided by the at least one light,

wherein the non-white color or a color temperature of the white color is determined by mixing particular amounts of the first radiation and the second radiation in response to the lighting control signal.

2. A method of claim 1, wherein the at least one light includes red, green and blue LEDs, wherein the illumination includes the white color, and wherein the white color is produced by a combination of radiation generated by the red, green and blue LEDs.

3. A method of claim 1, wherein the at least one first LED includes at least one white LED, wherein the illumination includes the white color, and wherein the white color is generated at least in part by the at least one white LED.

4. A method of claim 3, wherein the at least one second LED includes at least one non-white LED, and wherein the color temperature of the white color is determined by mixing the first radiation and the second radiation.

5. A method of claim 4, wherein the at least one second LED is selected from the group consisting of an amber source, a green source, a red source, a yellow source, an orange source, a blue source, and a UV source.

6. A method of claim 3, wherein the at least one second LED includes at least one second white LED having a color temperature different the at least one first white LED.

7. A method of claim 1, wherein the data provided by the at least one light is selected from the group consisting of control data, temperature data, performance data, performance history data, light histogram data, intensity data, color temperature data, on-off status data, color data, time data, total-on-time data, light show data, lighting effect data, alarm data, maintenance data, power-usage data, system status data, customer-entered data, advertising data, branding data, communications data and thermal history data.

8. A method of claim 1, wherein generating the lighting control signal comprises generating an addressed lighting control signal that is addressed to a connector to which the at least one light is coupled, the connector having an address associated therewith.

9. A method of claim 1, further comprising providing the data from the at least one light via onboard intelligence included in the at least one light.

10. A method of claim 9, wherein the data provided by the onboard intelligence indicates at least a partial or imminent failure of the at least one light.

11. A system comprising:

at least one light comprising at least one first LED configured to generate first radiation and at least one second LED configured to generate second radiation different from the first radiation; and

a control system configured to generate a lighting control signal for controlling the at least one light so as to provide illumination including at least one of a white color and a non-white light color, the control system further being configured to generate the lighting control signal based at least in part on data provided by the at least one light;

wherein the non-white color or a color temperature of the white color is determined by mixing particular amounts of the first radiation and the second radiation in response to the lighting control signal.

12. A system of claim 11, wherein the at least one light includes red, green and blue LEDs, wherein the illumination includes the white color, and wherein the white color is produced by a combination of radiation generated by the red, green and blue LEDs.

13. A system of claim 11, wherein the at least one first LED includes at least one white LED, wherein the illumination includes the white color, and wherein the white color is generated at least in part by the at least one white LED.

14. A system of claim 13, wherein the at least one second LED includes at least one non-white LED, and wherein the color temperature of the white color is determined by mixing the first radiation and the second radiation.

15. A system of claim 14, wherein the at least one second LED is selected from the group consisting of an amber source, a green source, a red source, a yellow source, an orange source, a blue source, and a UV source.

16. A system of claim 13, wherein the at least one second LED includes at least one second white LED having a color temperature different from the at least one first white LED.

17. A system of claim 11, wherein the data provided by the at least one light is selected from the group consisting of control data, temperature data, performance data, performance history data, light histogram data, intensity data, color temperature data, on-off status data, color data, time data, total-on-time data, light show data, lighting effect data, alarm data, maintenance data, power-usage data, system status data, customer-entered data, advertising data, branding data, communications data and thermal history data.

18. A system of claim 11, further comprising a connector coupled to the control system, wherein the at least one light is coupled to the connector, wherein the connector has an address associated therewith, and wherein the control system is configured to generate the lighting control signal as an addressed lighting control signal that is addressed to the connector.

19. A system of claim 11, wherein the at least one light comprises onboard intelligence to generate the data provided by the at least one light.

20. A system of claim 19, wherein the data generated by the onboard intelligence indicates at least a partial or imminent failure of the at least one light.
