FIELD: lighting.
SUBSTANCE: invention relates to lighting systems. Optical system (2A) for receiving and collimating light includes collimating unit (200) comprising at least one parabolic concentrator (CPC) (220, 230) forming inlet (212) and outlet (214) and configured to reflect light entering inlet (212) through the outlet (214) and limiting the angular divergence of the light to the size of the input angular aperture (θCPC), and homogenizing unit (300) to impart spatial homogeneity to the light emerging from collimating assembly (200), comprising a lens array of dual lenses of a condenser-type lenses based on a microlens array, in which light from outlet (214) collected by the first lens illuminates a corresponding second lens to form a continuously emitting output aperture.
EFFECT: increased brightness and uniformity of distribution of brightness over the area.
