Abstract
A uniform illumination lens is arranged between a light source and an illumination surface and has a light receiving surface and a light distribution surface, the light receiving surface has a first incident surface and a second incident surface; the light distribution surface has a first emergent surface and a second emergent surface which are connected with each other; all light entering from the first incident plane in the lens is totally reflected by the reflecting plane, reflected light is emitted through the first emergent plane and does not intersect with the first incident plane, and the second emergent plane receives all light entering from the second incident plane on one side of the normal. The lens provided by the invention provides uniform illumination at near and far positions of an irradiation surface.
