The advantages are as follows: the natural light collection capability of the apparatus is greatly expanded, and the utilization rate for a light source by equipment is improved. Furthermore, by using the semispherical compound eye natural light collector, solar energy equipment can break the restrictions of regions and can be popularized and used in a greater scope, and this has great significance for energy conservation and environmental protection. A total reflection light guide cylinder or a fiber whose mode can be selected is employed between the first optical condenser assemblies and a second optical condenser assembly, compared to a direct convergence mode, the optical energy transmission loss between two stages can be further reduced. The compound eye support at the surface in a mirror surface enables light which is scattered or is not converged to the light guide hole can still be guided to the light guide hole after reflection.
