Abstract
A luminaire capable of directing a high percentage of light source output in a downward direction includes a housing base, a light source mounted and electrically coupled to the housing base and a dome-shaped lens member made of light transmissive material disposed in surrounding relation to the light source. The lens member has a first region formed adjacent the housing base on which is disposed a first plurality of prismatic surfaces which both reflect and refract light in the downward direction. A second region is formed on the lens member adjacent the first region and includes a second plurality of prismatic surfaces which refract light output.
