Abstract:
A system for re-distributing light emitted from a light source using an optical element is described. The optical element is manufactured using a bulk matrix material, and diffusing particles and/or scattering particles are embedded within the bulk material. The optical element is coupled to the light source to capture emitted light and redistribute the light in a desired angular distribution pattern depending on the ratio of total weight of diffusing particles to total weight of scattering particles.
