A lens applied to a light emitting element includes a first surface profile and a second surface profile opposite to the first surface profile. The first surface profile defines a first trench facing the light emitting element, and the first trench includes a bottom curved surface serving as a light incident surface. The second surface profile includes a top curved surface, and serves as a light emitting surface. Both the bottom and the top curved surfaces are mirror symmetric to the first suppositional plane P(X=0), and mirror asymmetric to the second suppositional plane P(Y=0) to cooperatively adjust light from the light emitting element to obtain an asymmetric light field. An illumination device having the lens is further provided.

Lens and illumination device having same

An illumination device includes a light source module consisting of a substrate and a plurality of light emitting elements on the substrate in an array and an optical module array consisting of a plurality of optical modules covering the light emitting elements. Each optical module includes a first optical component and a second optical component. A first illumination distribution pattern is generated by light from the light emitting elements and modulated by the first optical components. A second illumination distribution pattern is generated by light from the light emitting elements and modulated by the second optical components. An illumination distribution pattern of the illumination device is superposition of the first illumination distribution pattern and the second illumination distribution pattern.
