Abstract (en)

An optical element (10), such as a lens and/or a reflector for lighting devices (L, 10), e.g. LED devices, includes: - a body (12) of the optical element (10), the body (12) providing a light propagation path towards a light emitting surface (14), and - an insert (16) coupled with said body (12), the insert (16) being interposed in the light propagation path, so that the optical characteristics of the light emitted from said light emitting surface (14) are a function of at least one among shape, position, material and texture of said insert (16).
