ABSTRACT:
A light assembly for wide area illumination employs a lens insert having a pair of opposed surfaces. One surface of the insert is defined by a series of closely spaced parallel prismatic refractors for directing light incident thereon generally in a first direction. The light assembly also includes arrays of optical elements for spreading light passing through the refractors in a pair of mutually orthogonal directions.
