Abstract

A lighting system provided for illuminating a region of an aisle in a theater, auditorium or the like, comprises a light housing attached to an aisle-side of a row-end theater or auditorium seat. Four individual miniature electric light sources, preferably high intensity light emitting diodes (LED'"'"'s), provide the illumination, and are mounted in the housing at a downwardly and outwardly facing housing window. A first focusing columniating primary lens installed in front of each LED and a second shaping secondary lens strip installed in series in front of the LED'"'"'s focus columniate and shape light emitted by the LED'"'"'s so as to cause illumination of a specific below-adjacent region of said aisle.

Claims

1. A system for illuminating a specific region of an aisle in a theater, auditorium or the like, the lighting system comprising;

a. a theater or auditorium seat;

b. a light housing attached to an aisle-side of the theater or auditorium seat;

c. at least one individual miniature electric light source;

d. a bracket for mounting said at least one individual miniature light source in said housing and for enabling the light from said at least one light source to be directed at particular regions of said aisle when the housing is mounted on the aisle side of said seat; and

e. primary light intensifying collimating lens and secondary light shaping lenses disposed in front of said at least one light source and configured so as to create a relatively uniformly illuminated region of said aisle.

2. The aisle lighting system as claimed in claim 1, wherein said at least one light source comprises a high intensity light emitting diode (LED).

3. The aisle lighting system as claimed in claim 1, including four of said light sources.

4. The aisle lighting system as claimed in claim 3, wherein each of said light sources comprises a high intensity light emitting diode.

5. A system for illuminating a specific region of an aisle in a theater, auditorium or the like, the lighting system comprising;

a. a theater or auditorium seat;

b. a light housing and means for attaching said housing to an aisle-side of said theater or auditorium seat;

c. an aisle lighting assembly mounted in said housing, said lighting assembly including at least four individual miniature electric light sources installed in a spaced apart relationship on a printed circuit card, a primary light intensifying collimating lens strip installed in front of said printed circuit card and a light shaping lens strip installed in front of said primary light intensifying collimating lens strip, so as to cause light from said light sources to illuminate specific regions of said aisle.

6. The aisle lighting system as claimed in claim 5, wherein each of said individual light sources include a high intensity light emitting diode.

7. The aisle lighting system as claimed in claim 5, wherein said primary light intensifying collimating lens strip includes an individual collimating lens in optical alignment with each of said light sources.

8. A system for illuminating a region of an aisle in a theater, auditorium or the like, the lighting system comprising;

a. a row-end theater or auditorium seat;

b. a light housing and means for attaching said housing to an aisle-side of the row-end theater or auditorium seat, said housing having a window facing outwardly and downwardly;

c. a lighting strip having mounted thereto at least four high intensity light emitting diodes mounted in said housing window; and

d. a first intensifying, collimating primary lens and a second shaping secondary lens strip installed in series in front of said lighting strip for intensifying, collimating and then shaping light emitted by said light emitting diodes so as to cause relatively uniform illumination of a below-adjacent region of said aisle.

9. A system for illuminating a specific surface region of an aisle in a theater, auditorium or the like, the lighting system comprising:

a row-end theater or auditorium seat;

a light housing attached to the row-end seat, said housing having a window facing outwardly and downwardly;

at least one miniature electric light source;

a bracket for mounting said at least one miniature light source in said housing such that a portion of said housing shields said at least one light source from being viewed from above;

a primary light collimating lens disposed in front of said at least one light source; and

a plurality of secondary light shaping lenses disposed in front of said primary lens, said secondary lenses configured to distribute light from the at least one light source to provide relatively uniform illumination of said specific surface region of said aisle.

10. The lighting system of claim 9, wherein said surface region is generally rectangular.
