Abstract

Techniques and architecture are disclosed for a lighting system for contained environments, such as elevators or other such environments. The lighting system can include one or more luminaires and/or one or more display devices that include tunable output controlled to automatically change the ambient lighting and/or presentable content (e.g., imagery, video, audio) based on one or more conditions related to the contained environment. Conditions that can be used in controlling the lighting system output within the contained environment can include, for example, the position or operation of the contained environment, the control of the contained environment, the occupancy within the contained environment, the time of day at the location of the contained environment, and the calendar date at the location of the contained environment. In some cases, the lighting system may constitute the general illumination within the contained environment, but may be supplemental as well.

Claims

1. A lighting system for a contained environment, the system comprising:

a luminaire including at least one solid-state light source and configured to recreate a lighting environment of a remote location in the contained environment;

a display device including a plurality of solid-state light sources and configured to display images from the remote location wherein the luminaire provides the lighting environment in concert with images displayed on the display device; and

a controller operatively coupled to the luminaire and the display device, wherein the controller is configured to automatically change the light output emitted in the contained environment by the luminaire and the display device based on a destination floor of the contained environment location, wherein the contained environment is an elevator.

2. The system of claim 1, wherein the light output constitutes approximately all of the illumination within the contained environment.

3. The system of claim 1, wherein the controller is configured to automatically change the light output in response to input provided to operate the contained environment.

4. The system of claim 1, wherein the controller is further configured to control at least one operation of the contained environment.

5. The system of claim 1, further comprising at least one sensor configured to determine occupancy within the contained environment.

6. The system of claim 5, wherein the controller is configured to automatically change the light output when the at least one sensor detects that occupancy has exceeded a predetermined threshold.

7. The system of claim 1, wherein the light output includes at least one of an image, scene, video, message, and advertisement.

8. The system of claim 1, wherein the display device is installed on or in at least one of the floor, ceiling, and wall of the contained environment.

9. The system of claim 1, further comprising a loudspeaker operatively coupled to the controller and configured to output audio in the contained environment based on the light output in the contained environment.

10. A method of controlling a lighting system for an elevator, the method comprising:

receiving input related to a destination floor of the elevator and at least one of;

the elevator position, the elevator occupancy, the time of day at the elevator location, and the calendar date at the elevator location; and

automatically changing light output within the elevator based on the input received, wherein the light output is emitted from solid-state light sources of a luminaire configured to recreate a lighting environment of a remote location in the elevator and a display device configured to display images from the remote location, wherein the luminaire provides the lighting environment in concert with images displayed on the display device based on the received input.

11. The method of claim 10, wherein the light output is automatically changed in response to movement of the elevator.

12. The method of claim 10, wherein the light output is automatically changed in response to input provided to operate the elevator.

13. The method of claim 10, wherein the light output includes at least one of an image, scene, video, message, and advertisement.

14. The method of claim 10, wherein the light output constitutes approximately all of the illumination within the elevator.

15. The method of claim 10, wherein the input is received from at least one sensor utilized to determine a condition of the elevator.
