Abstract
A total internal reflective (TIR) optic light bar of a lighting fixture configured to illuminate an object, such as a two-dimensional planar surface, the optic light bar including a body having a first end portion that extends to a second end portion through an elongated intermediate portion, the body including a light input surface extending between the first and second end portions, a total internal reflective (TIR) surface, and at least one light output surface, where the light output surface is formed as a gradual, continuous curve including a plurality of discrete segments that form a curvilinear surface, and where the TIR surface is composed of one or more of the discrete segments which form the curvilinear light output surface.
