Abstract

An illumination system includes a light assembly. The light assembly may include a housing having a first zone and a second zone isolated from the first zone. The housing may be configured to fit generally flush with a ceiling. A movable light source may be positioned within the first zone and is configured to emit a first light. A stationary light source may be positioned within the second zone and is configured to emit a second light.

Claims (27)

1. An illumination system, comprising:

a light assembly comprising a housing comprising a first zone and a second zone mechanically isolated from the first zone, the housing configured to align generally flush with a ceiling;

a movable light source positioned within the first zone and configured to emit a first light; and

a stationary light source positioned about the perimeter within the second zone and configured to emit a second light, wherein the movable light source comprises an array of LED light sources coupled to an arm and the arm is coupled to a belt sprocket assembly configured to rotate at least 360 degrees.

2. The illumination system according to claim 1 , wherein the first zone is centrally located within the housing and the second zone substantially surrounds the first zone.

3. The illumination system according to claim 1 , wherein the housing further comprises a rack at an upper portion thereof and the movable light source is coupled to the rack via a gear system disposed within the first zone.

4. The illumination system according to claim 1 , wherein the belt sprocket assembly is configured to rotate at least 540 degrees.

5. The illumination system according to claim 1 , wherein the array of LED light sources includes at least one of a red, orange, yellow, green, blue, infrared and ultraviolet light.

6. The illumination system according to claim 1 , further comprising:

at least one image sensor configured to collect image data in a field of view, wherein a controller adjusts the orientation of the first light based on the image data.

7. The illumination system according to claim 1 , further comprising:

at least one image sensor configured to identify a location of at least one of a marker and a wearable device in a field of view.

8. The illumination system according to claim 1 , further comprising:

a windowpane positioned on a bottom surface of the housing, wherein the windowpane comprises at least one of a laminated safety glass and an electrochromic element.

9. The illumination system according to claim 1 , wherein the movable light source comprises:

a tilt bracket;

rows of LED light sources; and

servo couplings configured to couple the rows of LED light sources to the tilt bracket.

10. The illumination system according to claim 1 , wherein the movable light source comprises rows of LED light sources and the rows of LED light sources are independently controlled for tilting movement.

11. A method for controlling an illumination system disposed in a housing configured to fit in an opening of a ceiling and comprising an illumination surface configured to align generally flush with the ceiling, the method comprising:

controlling a projection direction of a movable light source emitted from a central portion of the light assembly;

controlling ambient lighting from a stationary light source distributed about the central portion, wherein the stationary light source is mechanically disconnected from movement of the movable light source;

wherein controlling the movable light source comprises:

controlling a first rotation of a plurality of rows of lights about a first axis configured to rotate the plurality of rows parallel to the illumination surface; and

controlling a second rotation of a first row of the plurality of rows of lights about a second axis parallel to the illumination surface.

12. The method according to claim 11 , further comprising:

co-rotating a third rotation of a second row of the plurality of rows of lights in connection with the second rotation.
