Abstract

A lighting system (100) including at least one controller (102) and a memory (104) containing program portions which configure the controller (102) to obtain weather forecast information including one or more of current and expected weather conditions over a period of time; determine one or more lighting settings based upon the weather forecast information; form lighting setting information in accordance with the determined lighting settings; and transmit the lighting setting information. The system (100) may include an illumination source (106) to provide illumination in accordance with the lighting setting information The system may change characteristics (e.g., illumination pattern, illumination intensity, illumination spectrum, illumination polarization,) of the illuminated source (106). The process may form lighting setting information to control one or more filters (130) in accordance with a desired lighting setting.

Claims

1. A lighting system comprising at least one controller and a memory containing program portions which configure the controller to:

obtain weather forecast information comprising current and expected weather conditions over a period of time;

determine one or more lighting settings based upon the weather forecast information;

form lighting setting information in accordance with the determined lighting settings; and

transmit the lighting setting information.

2. The lighting system of claim 1, further comprising luminaires each having:

a transmitter receiver (Tx/Rx) which receives the lighting setting information;

at least one illumination source to provide illumination; and

a control portion to control the illumination source to provide illumination in accordance with the lighting setting information.

3. The system of claim 1, wherein the controller determines one or more power settings based upon the weather forecast information and forms corresponding power setting information.

4. The system of claim 3, further comprising a power portion comprising circuitry configured to selectively couple the luminaires to a selected power source of a plurality of power sources in accordance with the power setting information.

5. The system of claim 1, wherein the controller selects a power source of a plurality of power sources in accordance with weather forecast information.

6. The system of claim 1, wherein the controller determines the weather forecast information in accordance with one or more of sensor information and weather information, wherein the weather information is obtained from a weather resource.

7. The system of claim 1, wherein the lighting setting information comprises information related to one or more of illumination pattern, illumination intensity, illumination spectrum, illumination polarization, illumination frequency, and energy usage of luminaires of the system.

8. A computerized method of controlling a lighting system using a controller, the method comprising acts of:

obtaining weather forecast information comprising one or more of current and expected weather conditions;

determining one or more lighting settings based upon the weather forecast information;

forming lighting setting information in accordance with the determined lighting settings; and

transmitting the lighting setting information.

9. The method of claim 8, further comprising acts of:

receiving the lighting setting information; and

controlling an illumination source to provide illumination in accordance with the lighting setting information.

10. The method of claim 8, further comprising acts of

determining one or more power settings based upon the weather forecast information;

and

forming corresponding power setting information.

11. The method of claim 10, further comprising an act of coupling luminaires to a selected power source of a plurality of power sources in accordance with the power setting information.

12. The method of claim 8, further comprising an act of selecting a power source of a plurality of power sources in accordance with weather forecast information.

13. The method of claim 8, further comprising an act of determining the weather forecast information in accordance with one or more of sensor information and weather information, wherein the weather information is obtained from a weather resource.

14. The method of claim 8, further comprising forming the lighting setting information to include information related to one or more of illumination pattern, illumination intensity, illumination spectrum, illumination polarization, frequency, and energy usage of luminaires of the system.

15. A computer program stored on a computer readable non-transitory memory medium, the computer program configured to provide a user interface (UI) to accomplish a task, the computer program comprising a program portion configured to:
