Abstract

A lighting system for use in areas of low-level lighting, such as a planetarium, theater, museum, or auditorium, which improves visibility of objects without detracting from the overall desired low-level lighting. The lighting system provides a safe and low cost way to illuminate certain areas of a darkened room while maintaining an overall dimly lit environment.

Claims

1. A lighting system for use in a theater, auditoriurm, museum or planetarium having a low level of ambient light, the lighting system comprising:

a seating structure having a back;

at least one light source disposed adjacent said back of said seating structure; and

a light blocking member disposed adjacent said at least one light source, said light blocking member being stationary with respect to said light source and said back such that at least a portion of light emitted by said at least one light source constantly illuminates an area adjacent said lighting system, and said light blocking member preventing projection of said light directly into the eyes of a person adjacent said lighting system;

wherein said lighting system does not significantly increase the level of ambient light in a theater, auditorium, museum or planetarium.

2. The lighting system of claim 1 wherein said back is disposed along a plane which is between 30 and 120 degrees relative to a supporting surface disposed beneath said seating structure.

3. The lighting system of claim 2 wherein said back is disposed along a plane which is between 60 and 90 degrees relative to said supporting surface disposed beneath said seating structure.

4. The lighting system of claim 3 wherein said back is disposed along a plane which is substantially vertical relative to said supporting surface disposed beneath said seating structure.

5. The lighting system of claim 1 wherein said light source is integral with said back.

6. The lighting system of claim 1 wherein said light blocking member comrprises a cavity in said back and wherein said light source is disposed within said cavity.

7. The lighting system of claim 1 wherein said light blocking member comprises:

a cover extending from said back of said seating structure for blocking a major portion of light emitted from said light source to thereby prevent projection of said light directly into the eyes of a person adjacent said lighting system.

8. The lighting system of claim 7 wherein said light source is affixed to at least one of said back of said seating structure or said cover.

9. The lighting system of claim 7 wherein said cover has an edge which is distal to said back of said seating structure and extends in a downward direction toward said supporting surface.

10. The lighting system of claim 1 wherein said light source emits light having a wavelength corresponding to at least one of red light or green light.
