Abstract

The present invention is directed to a multi-zoned lighting apparatus. In one embodiment, the multi-zoned lighting apparatus includes at least one circuit board, at least one control circuit coupled to the at least one circuit board and a plurality of light emitting diode (LED) groups coupled to the at least one control circuit, wherein each LED group of the plurality of LED groups is in communication with a respective external sensor that controls a respective one of the plurality of LED groups when triggered.

Claims

1. A multi-zoned lighting apparatus comprising:

at least one circuit board;

at least one control circuit coupled to said at least one circuit board; and

a plurality of light emitting diode (LED) groups coupled to said at least one control circuit, wherein each LED group of said plurality of LED groups is in communication with a respective external sensor, wherein said each LED group of said plurality of LED groups is independently controlled via said respective external sensor in communication with said at least one control circuit when said respective external sensor is triggered to turn on when said respective external sensor detects an object, wherein an illumination level of one of said plurality of LED groups is determined based on a type of object that is detected by said respective external sensor, wherein said type of object is detected based upon a speed of said object or an image recognition of said object, wherein a first illumination level is used when said type of object detected is a person and a second illumination level is used when said type of object detected is a vehicle, wherein the second illumination level is lower than the first illumination level, wherein each one of said plurality of LED groups within a single lighting apparatus illuminates a different zone.

2. The multi-zoned lighting apparatus of claim 1, wherein each one of said plurality of LED groups comprises a plurality of LEDs.

3. The multi-zoned lighting apparatus of claim 1, wherein each LED group of said plurality of LED groups is independently controlled comprises changing an illumination level of one of said plurality of LED groups without changing an illumination level of remaining ones of said plurality of LED groups.

4. The multi-zoned lighting apparatus of claim 3, wherein said illumination level comprises at least one of:

an on level, an off level or a gradation of illumination between the on level and the off level.

5. The multi-zoned lighting apparatus of claim 1, wherein each one of said plurality of LED groups provides at least 10 lumens per square meter.

6. The multi-zoned lighting apparatus of claim 1, further comprising:

a controller coupled to said respective external sensor.

7. The multi-zoned lighting apparatus of claim 1, wherein at least one LED on each one of said plurality of LED groups is coupled to an optic.

8. A method for providing multi-zoned illumination using a single lighting apparatus, comprising:

powering said single lighting apparatus having a plurality of light emitting diode (LED) groups, each one of said plurality of LED groups having at least one LED; and

controlling each one of said plurality of LED groups independently of one another via a respective external sensor in communication with a control circuit when said respective external sensor is triggered to turn on when said respective external sensor detects an object, wherein an illumination level of one of said plurality of LED groups is determined based on a type of object that is detected by said respective external sensor, wherein said type of object is detected based upon a speed of said object or an image recognition of said object, wherein a first illumination level is used when said type of object detected is a person and a second illumination level is used when said type of object detected is a vehicle, wherein the second illumination level is lower than the first illumination level, wherein each one of said plurality of LED groups within the single lighting apparatus illuminates a different zone.

9. The method of claim 8, wherein an illumination level of all remaining LEDs of other ones of said plurality of LED groups remains unchanged.

10. A system for providing multiple points of multi-zoned illumination, comprising:

a plurality of lighting apparatuses, each one of the plurality of lighting apparatuses comprising;

a plurality of light emitting diode (LED) groups, wherein each LED group of said plurality of LED groups is independently controlled and illuminates a different zone; and

at least one LED coupled to each one of said plurality of LED groups;

at least one sensor coupled to each one of said plurality of lighting apparatuses; and

a central controller remotely located from said plurality of lighting apparatuses and in communication with said plurality of lighting apparatuses, wherein each one of the plurality of LED groups is independently controlled via the at least sensor in communication with said central controller when said at least one sensor is triggered to turn on when said at least one sensor detects an object, wherein an illumination level of one of said plurality of LED groups of one of said plurality of lighting apparatuses is determined based on a type of object that is detected by said at least one sensor, wherein said type of object is detected based upon a speed of said object or an image recognition of said object, wherein a first illumination level is used when said type of object detected is a person and a second illumination level is used when said type of object detected is a vehicle, wherein the second illumination level is lower than the first illumination level.

11. The system of claim 10, wherein each one of said plurality of lighting apparatuses is in communication with one another.

12. The system of claim 11, wherein each one of said plurality of lighting apparatuses communicates with one another via radio frequency (RF).

13. The system of claim 10, further comprising:

a hub for relaying communications between said central controller and each one of said plurality of lighting apparatuses.

14. The system of claim 13, wherein one or more mobile devices communicate with said plurality of lighting apparatuses via said hub.
