Abstract
A lens and light source module include: a light receiving surface; a light distribution surface, along the optical axis direction set opposite to the light receiving surface; light receiving surface away from the optical axis center region to form N groups of projection, where N≥1; each with a first incident surface and a first reflective surface. The first incident surface is adapted to refracting light to the first reflective surface; the first reflective surface is adapted to reflecting light to a light distribution surface and refracting light to a display by the light distribution surface. The lens provided by the present invention enables the majority of light to be directed to the shelf in a targeted manner, which is conducive to achieving balanced light distribution and enhancing light efficiency.
