| 技術摘要 / Our Technology： |
The present invention provides a composite light guiding curved surface structure, comprising a structure body and at least one light source. The structure body comprises a light-receiving surface being provided with a plurality of curved surfaces formed thereon, each of which being provided with a plurality of micro lenses. Each micro lens is further provided with a plurality of sub-wavelength anti-reflecting structures. The sub-wavelength anti-reflecting structures also cover the entire curved surface among lenses. At least one light source is disposed on one side of the light-receiving surface to generate a light field projecting to each of the curved surfaces on the light-receiving surface. In the present invention, the micro lens is capable of increasing the diffusing angle for light diffusion; meanwhile, the sub-wavelength anti-reflecting structures are capable of increasing the light transmission efficiency to reduce loss of light at the interface and enhance the utilization of light.
