Abstract:
A light fixture, comprising:a light source; andan optical element comprising a polymeric first phase and a second phase disposed within said first phase, said second phase being discontinuous along at least two of any three mutually perpendicular axes;wherein said first and second phases have indices of refraction which differ along a first axis by more than about 0.05 and which differ along a second axis orthogonal to said first axis by less than about 0.05, wherein said optical element has a total reflectivity of greater than about 50% for light emitted by said light source which is polarized along a first axis and a total transmission of greater than about 50% for light emitted by said light source which is polarized along a second axis, and wherein said second axis is orthogonal to said first axis.
