Abstract: A lens, which is adapted to control distribution of light emitted by a light source, includes a curved light-projecting surface distal from the light source, and a light-incident surface opposite to the light-projecting surface. The light-incident surface includes a plurality of curved sections facing the light source, and a plurality of connecting sections. Each of the connecting sections interconnects two adjacent ones of the curved sections, and has opposite first and second connection sides that are respectively connected to the two adjacent ones of the curved sections. A distance between the first connection side and the light source is not equal to a distance between the second connection side and the light source.
