Patent attributes
An optical system (2A) is disclosed for receiving and collimating light, wherein the optical system (2A) comprises a collimation unit (200) comprising at least one parabolic interface (220, 230) that defines an inlet opening (212) and an outlet opening (214), wherein the at least one parabolic interface (220, 230) is configured to reflect light entering through the inlet opening (212) through the outlet opening (214) and limit the angular spread of the light to an acceptance angle (θCPC) associated with the at least one parabolic interface (220, 230); and a homogenization unit (300) for homogenizing the light emerging from the collimation unit (200), the homogenization unit (300) comprising a lens array with pairs of a first lens and a second lens, wherein the lens array is configured such that light from the outlet opening (214) collected by a first lens illuminates the respective second lens to provide for a continuously emitting output aperture.
