FIELD: lighting.
SUBSTANCE: lighting system (100) comprises a light emitting unit (101) configured to emit a light field (103) with a predetermined uniformity of directivity and an optical element (102) configured to receive a portion of the light field (103) emitted by the light emitting unit (101), and configured to output the modified light field (104) based on the light field (103). The optical element (102) is set separately with respect to the light emitting unit (101) and is configured to change the light field (103) introduced into the optical element (102) such that the light field (104) output from the optical element (102) has a changed uniformity of directivity with respect to the light field (103) emitted by the light-emitting unit (101). In addition, the optical element (102) is disclosed, and configured to be included into the lighting system (100).
EFFECT: creating of a light field with a possibility of changing of its direction uniformity.
