FIELD: physics.
SUBSTANCE: method includes forming, within the transparent body of a concentrator, light guide sectors, placing in each sector volumetric annular mirrors for double reflection of light flux coming from the radiation source. Uniform concentration of the light flux is generated by the curvature, focusing and defocusing of the mirrors. An intermediate thin annular mirror is used in the central sector.
EFFECT: generating uniform light flux in a given solid angle for a light flux concentrator of a point radiation source.
