Abstract
A prismatic lens and a reflector/refractor device having enhanced characteristics are provided for lighting fixtures. The prismatic lens and the reflector/refractor device are formed of a silicone material. A prismatic lens member includes a plurality of prisms on a surface thereof for refracting light. The reflector/refractor device includes a plurality of prisms on a surface thereof for reflecting and refracting light. The silicone material forming the prismatic lens and the reflector/refractor device is substantially transparent, and enables forming enhanced optical elements, for example, by injection molding technique. The silicone material is a selected one of dimethylsilicone, phenylmethlysilicone, or similar silicone material enabling enhanced optical performance for the prismatic lens and the reflector/refractor device.
