Claims10
A retaining frame having at least one optical element secured thereto by injection molding, with the at least one optical element being configured to beam shaping by at least one of total internal reflection and diffraction;
- wherein the optical element includes at least two laterally arranged projections for securing the optical element to the retaining frame, and
- wherein said at least two laterally arranged projections are held on the retaining frame by a marginal arch, the optical element being molded to the retaining frame only at said laterally arranged projections by said marginal arch while a remaining surface of the optical element is not connected to the retaining frame.
A method for producing a system comprising a retaining frame and an optical element secured thereto, the method comprising:
- injection-molding the retaining frame;
- and
- molding the optical element to the retaining frame while performing the injection molding of the frame only at at least two laterally arranged securing projections;
- wherein the optical element is molded to the retaining frame only at said at least two laterally arranged securing projections by a marginal arch while a remaining surface of the optical element is not connected to the retaining frame.
