摘要
A Fresnel condenser device and a condenser-type solar energy system are provided, wherein the condenser device comprises first and second Fresnel lens layers, each lens layer comprising at least one condenser-type Fresnel lens; and a straight box-shaped light guiding layer, the first and second Fresnel lens layers being disposed respectively on two ends thereof, and the straight box-shaped light guiding layer is configured to direct a light from the first Fresnel lens layer down to the second Fresnel lens layer. By utilizing two Fresnel lens layers to respectively perform light convergence and using the straight box-shaped light guiding layer therebetween to help direct the light from an upper layer to a lower layer, the condenser device can not only adapt to a wide range of incident angles, but also obtain a large light convergence ratio at a low height.
