Abstract

See full text

The present invention discloses a Fresnel lens with a light receiving effect, including a converging surface and an incidence surface opposite to the converging surface. The incidence surface is provided with an optically effective refractive region and an optically reflective region annularly surrounding the optically effective refractive region. The optically reflective region is provided at least with a prism annularly disposed outside the optically effective refractive region. The prism is provided with a refraction surface which is in adjacent to the optically effective refractive region and a reflection surface which is disposed at a first angle relative to the refraction surface. In addition, a tail end of the prism is an inverted hook part. Therefore, the effective working area of the refraction surface and the reflection surface can be increased, thereby improving the light receiving effect of the Fresnel lens.
