Abstract: A lighting system is disclosed. The lighting system includes a first selectively actuated light module that emits light having a first polarization orientation. A second selectively actuated light module emits light having a second polarization orientation that is orthogonal to the first polarization orientation. A first combining element combines and directs light from the first and second light modules into an optical path. A first polarization alignment element aligns the polarization of light from the first combining element to a predetermined polarization orientation. The first and second light modules are selectively actuated to ensure that light having the predetermined polarization orientation is substantially constantly emitted when desired.

Abstract: A light shielding and reflecting device is connected to a luminaire reflector that is quickly and easily adjustable to alter the emitted beam configuration. The luminaire includes a housing, a lamp with optical sides mounted in the housing, a main reflector mounted in the housing about the lamp, and a removable reflector shield having a plurality of tabs releasably engaging openings in the main reflector. The shield is positioned to block light from emitting into an undesired area and redirects that light to a desired area. A second shield can be used depending on the desired beam configuration.
