ABSTRACT:
A light fixture has a reflector having a part-elliptical surface and having at least one focal point at which is provided an LED set behind a main shield that prevents light from passing directly out of the light through a light-output plane. The reflector surface is shaped as an ellipse outside the apex point and adjacent the one focal point of the ellipse at which the LED is located. An arcuate portion of the ellipse segment defines the light-output plane, and the reflector surface extends along a longitudinal straight line. The LED, a straight longitudinally extending free edge of the main shield, and a straight longitudinally extending free edge of the reflector surface or a longitudinally extending straight edge of a secondary shield positioned generally at the outer free edge of the reflector surface lie in a common plane.
