Abstract

A lighting element is disposed in an array of lighting elements. At the lighting element, a lighting status of at least one neighboring lighting element is sensed. Independent of any other lighting element, a lighting adjustment for the lighting element by applying the sensed lighting status to a predetermined rule is determined. The lighting adjustment is applied to the lighting element to adjust an illumination of the lighting element.

Claims (41)

1. A method of illuminating a first lighting element and a second lighting element, the first lighting element disposed in a first housing and the second lighting element disposed in a second housing, the method comprising:

sensing an illumination lighting status of the second lighting element;

determining an illumination adjustment for the first lighting element by applying the sensed illumination status to a status rule, wherein the status rule defined as a light status or a condition of the second lighting element;

applying the illumination adjustment to the first lighting element to adjust an illumination of the first lighting element, the applying being effective to control illumination of the first lighting element independently from the illumination of the second lighting element.

2. The method of claim 1 wherein sensing the illumination status comprises sensing a color level of the second lighting element.

3. The method of claim 1 wherein the sensed illumination status indicates whether the second lighting element is on or off.

4. The method of claim 1 wherein applying the sensed illumination status to the status rule produces an illumination adjustment, and wherein applying the illumination adjustment comprises adjusting the intensity level or the color of the first lighting element.

5. The method of claim 1 wherein the second lighting element comprises eight lighting elements.

6. A light element fixture, the fixture comprising:

a first lighting element;

a first sensor configured to sense an illumination status of a second lighting element;

a memory, the memory configured to store a status rule, wherein the status rule defined as a light status or a condition of the second lighting element;

a first processor coupled to the first lighting element, the first sensor, and the memory, the first processor being configured to determine an illumination adjustment for the first lighting element by applying the sensed illumination status to the status rule, the first processor being further configured to apply the illumination adjustment to the first lighting element to adjust an illumination of the first lighting element;

wherein a first housing having disposed therein the first lighting element, the first sensor, the memory, and the first processor;

wherein the second lighting element is disposed in a second housing that includes a second processor and a second sensor, such that the second processor is configured to control illumination of the second lighting element, the illumination of the second lighting element being controlled independently from the illumination of the first lighting element and the illumination of the first lighting element being controlled from the illumination of the second lighting element independently.

7. The light fixture element of claim 6 wherein the first sensor and the second sensor are configured to sense light intensity.

8. The light fixture element of claim 6 wherein the first sensor and the second sensor are configured to sense color.

9. The light fixture element of claim 6 wherein the first sensor is disposed along periphery of the first housing.

10. The light fixture element of claim 6 wherein the rule produces an illumination intensity adjustment.

11. The light fixture of claim 6 wherein the first lighting element comprises at least one light emitting diode.

12. A lighting array, the array comprising:

an array housing including a first light element fixture and a second light element fixture;

wherein the first light element fixture include:

a first lighting element,

a first sensor configured to sense a second illumination status of at least a second lighting element;

a first memory configured to store a first status rule, wherein the first status rule defined as a light status or a condition of the second lighting element;

a first processor coupled to the first lighting element, the first sensor, and the first memory,

the first processor being configured to determine a first illumination adjustment for the first lighting element by applying the sensed second illumination status to the first status rule, the first processor being further configured to apply the first illumination adjustment to the first lighting element to adjust an illumination of the first lighting element;

a first housing having disposed therein the first lighting element, the first sensor, the memory, and the first processor;

wherein the second light element fixture includes:

the second lighting element,

a second sensor configured to sense a first illumination status of at least the first lighting element;

a second memory configured to store a second status rule, wherein the second status rule defined as a light status or a condition of the first lighting element;

a second processor coupled to the second lighting element, the second sensor, and the second memory,

a second housing having disposed therein the second lighting element, the second sensor, the second memory, and the second processor;

the second processor being configured to determine a second illumination adjustment for the second lighting element by applying the sensed first illumination status to the second status rule, the second processor being further configured to apply the second illumination adjustment to the second lighting element to adjust an illumination of the second lighting element;

wherein illumination of the second lighting element is controlled independently from the illumination of the first lighting element and the illumination of the first lighting element being controlled from the illumination of the second lighting element independently.

13. The lighting array of claim 12 wherein each of the first light element fixture and the second light element fixture comprises at least one additional sensor that is configured to sense illumination status.

14. The lighting array of claim 13 wherein the first sensor and the second sensor are configured to sense color.

15. The lighting array of claim 13 wherein the first sensor is disposed along periphery of the first housing.

16. The lighting of claim 12 wherein the first light element and the second lighting element comprises at least one light emitting diode.
