摘要： The present invention refers to an optical element (1) for controlling a light distribution pattern of a light source (13) radiating light beams (L) to a geometric half-space (H1) being defined by a geometric plane (Pi), wherein the optical element (1) is integrally made of a transparent piece (2) and comprises a base plate (3) of the transparent piece (2), a lens section (4) of the transparent piece (2), and a cavity (5) in the transparent piece (2). The part of the cavity (5) extending through the base plate (3) defines a bottom cavity space (50) which is circumferentially delimited by a redirection surface of the transparent piece and continuously tapers towards the lens section. An angle α of the redirection surface (6), with respect to the geometric plane (P1), at any part along its circumference is defined such that light propagating through the base plate (3) by internal total reflection towards the cavity (5) is redirected at the redirection surface (6) by total internal reflection towards the geometric half-space (H1) and preferably directly into the lens section (4).

摘要： A beam-shaping lens includes a first surface including a smooth-shaped concave surface; and a second surface including a convex surface substantially similar in shape to the concave surface. The beam-shaping lens converts a first light beam that is parallel light incident on the first surface and having a light intensity distribution that continuously increases from an outer periphery toward a center, into a second light beam that has a flatter light intensity distribution than that of the first light beam.
