Abstract

The invention provides A light management system for an outdoor lighting network system, comprising a plurality of outdoor light units wherein at least one light unit includes at least one sensor type, a central management system in communication with light units, said central management system sends control commands to one or more of said outdoor light units, in response to received outdoor light unit status/sensor information from one or more of said outdoor light units and implement a lighting strategy relating to the lighting characteristics of the plurality of outdoor light units, wherein the central management system uses the light unit status/sensor information to form a user'"'"'s behavior analyses, and determine or estimate or predict the user'"'"'s motion trajectory and/or position and a change in a user-controlled light use and/or ambient light, and determine whether to modify the lighting strategy and/or reconfigure one or more of the lights units.

Claims

1. A light management system for an outdoor lighting network system, comprising:

a plurality of outdoor light units wherein at least one light unit includes at least one sensor type;

a central management system in communication with light units, said central management system sends control commands to one or more of said outdoor light units, in response to received outdoor light unit status/sensor information from one or more of said outdoor light units and implement a lighting strategy relating to the lighting characteristics of the plurality of outdoor light units;

wherein the central management system uses the light unit status/sensor information to determine a current user'"'"'s behavior, wherein the central management system stores history information relating to user behavior, relating to at least one of the plurality of outdoor light units, that includes at least two or more of dimming schedule, user speed, ambient light level, traffic volume and weather status, based on date and time, and determining the current user'"'"'s behavior based on a deviation to the stored history information, wherein determining the current user'"'"'s behavior includes determining a current user deviation in user-controlled light level to the stored history information, and determine whether to modify the lighting strategy.

2. The system of claim 1, wherein the central management systems further determines a user'"'"'s behavior by determining a change in the user'"'"'s speed.

3. The system of claim 1, wherein the central management systems further determines a user'"'"'s behavior by determining a user'"'"'s driving patterns.

4. The system of claim 3, wherein a sensor sends sensor data regarding a user driving pattern to the central management system, wherein the central management system determines the user'"'"'s driving pattern by analyzing whether the user is in compliance with traffic lights, road signs or warnings, and if the user is weaving/swerving, getting off the road, and measuring time in a passing/overtaking road lane.

5. The system of claim 1, wherein the central management system reconfigures one or more of the lights units based on the modified lighting strategy.

6. The system of claim 1, wherein the modified lighting strategy includes modifying the light characteristics of subsequent light units along the estimated position or trajectory of the user.

7. The system of claim 1, further including at least one user input/output device in communication with at one or more of said outdoor light units, wherein the central management system provides information to the at least one user input/output device.

8. The system of claim 1, further including a resource server in communication with said central management system, wherein the central management system uses resources from the resource server to further modify the lighting strategy and/or reconfigure one or more of the lights units.

9. A method of light management for outdoor lighting network system, the outdoor lighting network having a plurality of outdoor light units wherein at least one light unit includes at least one sensor type, and a central management system in communication with the outdoor light units, the method comprising the steps of:

receiving, in the central management system, status/sensor information from the at least one sensor type;

storing, in the central management system using the status/sensor information, history information relating to user behavior, relating at least one of the plurality of outdoor light units, that includes at least two or more of dimming schedule, user speed, ambient light level, traffic volume and weather status, based on date and time;

determining a current user'"'"'s behavior based on a deviation to the stored history information, wherein determining the current user'"'"'s behavior includes determining a current user deviation in user-controlled light level to the stored history information;

determining whether to modify the lighting strategy based on the user behavior.

10. The method of claim 9, wherein the determining a user'"'"'s behavior further includes determining a change in the user'"'"'s speed.

11. The method of claim 9, determining a user'"'"'s behavior further includes determining a user'"'"'s driving patterns.

12. The method of claim 11, wherein determining a user'"'"'s driving patterns includes analyzing whether the user is in compliance with traffic lights, road signs or warnings, and if the user is weaving/swerving, getting off the road, and measuring time in a passing/overtaking road lane.

13. The method of claim 9, further including the step of reconfiguring one or more of the lights units.

14. The method of claim 11, wherein modifying the lighting strategy includes modifying the light characteristics of subsequent light units along the estimated position or trajectory of the user.

15. The method of claim 11, further including at least one user input/output device in communication with at one or more of said outdoor light units, and the step of, the central management system, providing information to the at least one user input/output device.

16. The system of claim 11, wherein the step of modifying the lighting strategy and/or reconfigure one or more of the lights units includes receiving information from a resource server in communication with said central management system.
