FIXED SOLAR RADIATION CONCENTRATOR WITH OPTICAL METHOD OF ALIGNMENT Russian patent published in 2018 - IPC F24S23/30 G02B19/00 H02S40/22 G02B3/08 

FIELD: physics.

SUBSTANCE: fixed solar radiation concentrator implements the alignment of a light flux on the input end of the focusing cone due to the narrowing of the light flux in two perpendicular planes and contains three focusing flat linear echelon lenses, while the second echelon lens lies at the focus of the first short-focus linear echelon lens and the third linear short-focus echelon lens, in the focus of which the focusing cone is located, is located behind the second echelon lens. Second echelon lens consists of strip long-focus linear echelon lenses shifted step by step in relation to each other in the longitudinal direction, the axis of symmetry of the strip lenses are rotated 90 degrees relative to the symmetry axes of the first and third lenses. Focal lengths of the second lens and the optical system of the first and third lenses coincide.

EFFECT: increase in the density of the output light flux, reduction of the weight of the concentrator, reduction of the wind load, increase in the concentrator's working time during the day, service life and reliability, regardless of electricity.
