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.
