Abstract

A lighting system having a reflector with a plurality of reflecting surfaces. The plurality of reflecting surfaces have at least one optical axis, and the reflecting surfaces further include a linearly projected cross-section along a respective linear axis. A plurality of light emitting diodes (LEDs) are positioned in a line generally parallel to the linearly projected cross-section of the plurality of reflecting surfaces. The LEDs are oriented relative to an associated reflecting surface such that a central light-emitting axis of the plurality of LEDs is angled relative to the at least one optical axis of the associated reflecting surface at about 45°. The reflecting surfaces redirect and collimate a light output of the plurality of LEDs at an angle of about 45° with respect to the central light emitting axis of the plurality of LEDs.
