Abstract:
An optical module and a lighting device. The optical module comprises a polarizing lens (20). The polarizing lens (20) comprises: a lens body (23), one side of the lens body (23) being provided with a recess (231), and the other side of the lens body (23) being provided with a protrusion (232); a light incident surface (21), which is the bottom surface of the recess (231) and is a symmetrical spherical crown or ellipsoid crown or eccentric spherical surface; and a light exit surface (22), which is the surface of the protrusion (232), is provided opposite to the light incident surface (21), and is an eccentric spherical surface. By adjusting the relative position of a light emitting unit (30) and the polarizing lens (20), the adjustment of the light distribution angle of the light emitting unit (30) by the polarizing lens (20) is achieved, and thus the optical module can be universally used in various occasions.
