Abstract
A light assembly that includes a base, a housing extending from the base having a partial paraboloidal cross-sectional surface, a light-shifting element disposed within the housing, and a plurality of light sources coupled to the housing. The light sources generate light. The light assembly also includes an angular portion reflecting light from the light sources toward the parabolic cross-sectional surface so that the light reflected from the parabolic surface is directed toward the light-shifting element and light reflected from the light-shifting element is directed out of the housing after reflecting from the housing.
