Abstract

A lens includes a light incident surface and a light output surface. The light incident surface includes a first region having points equidistant from the central point of a light emission surface of the light emitting element. The first region satisfies θa≦θ≦θb, wherein θis a first incident angle of any light emitting from the light emitting element. In a second region with 0°<θ≦θb+20°, the first incident angle of light having a minimum value of θis between θa and θb, and θ>0.9. In a third region with 0°<θ≦θb+10°, the first incident angle of light having a minimum value of θis between θa and θb, and θ>0.9. θis a second incident angle of the light of θwhen traveling in the lens, and θis a third incident angle of the light of θwhen emitting out of the lens.
