The second power unit 121 is provided on the support 111 together with the reflection plate 112. As shown in the figure, which is a schematic diagram of the optical path of the present embodiment, the incident light L1 is reflected by the reflective plate 112, and the reflected light L2 exits toward the light-receiving surface 20.

As shown in fig. 5, the azimuth angle γ of the sun is obtained, and the first power device 122 is controlled to rotate around the first rotating shaft 114 according to γ, so that the angle θ between the projection of the reflecting plane in the horizontal direction and the horizontal plane is 90 ° - γ. At this time, the reflector 112 faces the sun, and the maximum irradiance can be obtained, and accordingly the energy reflected to the light-receiving surface 20 is the most, and the intensity of the reflected illumination is stronger.
The calculation method of the solar azimuth angle gamma comprises the following steps:
in the method, the control device 13 adjusts the reflector 112 to rotate around the second rotation axis 113, so that the included angle between the reflecting plane and the horizontal plane is consistent with the included angle θ between the reflecting plane and the horizontal plane.
