Abstract: An optical lens component (1) comprises a central lens element (3) having an optical axis (5) and located centrally of a circumjacent mounting portion (7) having spaced parallel surfaces (13A, 13B) that extend perpendicularly to said optical axis. At least one of said spaced parallel surfaces is provided with a non-random light-scattering structure (23A, 23B) for coupling out light entering said mounting portion. The non-random light-scattering structure may comprise indentations having parallel light-scattering surfaces having predetermined inclinations relative to said spaced parallel surfaces, such as an array of concentric circular indentations centered on said optical axis of the lens element. The optical lens component is preferably a molded integral lens component. Then the light-scattering structure may be provided by molding with the molded optical lens component, preferably into the molded optical lens component.
