    This invention relates to optical devices designed to concentrate solar radiation at a linear focus. The famous solar concentrator, made on the basis of reflectors forming the Fresnel surface, however, this concentrator has a small aperture relative to the focal distance of the reflector. The mirror concentrator of solar rays is known, containing a flat base and a number of reflective flat elements, each of which is located at a corresponding angle | i to the base 2J. A disadvantage of the known device is that as its aperture increases, some of the rays reflected from the flat elements block the vertical facets of adjacent steps of flat elements, which reduces the efficiency of concentration of rays in the device focus. The aim of the invention is to increase the effectiveness of the concentration. This goal is achieved by the fact that in a mirror concentrator of solar rays containing a flat base and a number of reflecting flat ones. elements, each of which is located at a corresponding angle to a flat base, a flat base is located at an angle Q greater than 0 but less than 90, to the normal to the direction of radiation, and ups B are chosen from the ratios ft tf-ci, where. od is the angle between the flat reflecting element and the normal to the direction of radiation. In addition, the angle of inclination of the planar base Cf is greater than or equal to half the angle | formed by direct connecting the focus of the concentrator and the extreme points of the base. Figure 1 shows a vertical section, a hub; Fig. 2 is a diagram defining the geometrical parameters of the device; FIG. 3 shows a variant of the device with internal tearing elements, FIG. 4 is an example of a mirror concentrator. The device contains a flat base 1 and flat reflective zlengits 2 located on it, made in the form of steps with a face 3 perpendicular to the base. The side reflective elements are inclined with respect to the base at an angle, and with respect to the hand perpendicular radiation at an angle o (. The flat base is inclined with respect to the perpendicular to the radiation at an angle. The device operates as follows. The sun's rays fall on flat elements 2, and since each of them is inclined at an appropriate angle L to the base, They are common to the common linear focus 4. Due to the inclination of the flat base and the reduced ratios of ° C, f, the rays falling on the concentrator are not blocked by the faces of the 3 elements 2. And all are collected in the general focus. reflecting elements 2 to the focus 4, resulting in less defocusing of the reflected rays in this device. The solar concentrator can also be made with an internal reflective surface (fig. 3, In this case, the flat reflective surfaces 2 Vanir on the lower side of the transparent resin diet 5 via the reflecting coating 6 thus obtained reflective reinforcing panel 7 is based on shgoskom 1. With this, the hub structure reflecting surface elements 2 are protected from the environment. When assembled, the concentrator is a rigid supporting structure of the 8-shaped form, on which flat reflecting elements 2 are located (Fig. 4). In linear focus 4 Disposed photodetectors. The angle Jj formed by direct connecting the focus of the concentrator and the extreme points of the base is chosen depending on the type of photodetector (Fig. 2}. If this angle is determined, then the minimum angle of base inclination (at which no radiation is blocked by the steps of reflectors) is equal to (p J / 2. The required base length PL is calculated using the formula sjny
    where FD is the distance from the focus to the lowest point of the base.
    The effective aperture of the entire mirror concentrator of sunlight is equal to ЕА PL-cbsCf.
    . The proposed device, compared with concentrators with a horizontal base with a similar aperture and focal length, allows an increase in the efficiency of the concentration by approximately 9%.
