COMPOSITE MOLDED LENS AND METHOD FOR PRODUCING THE SAME

摘要

In a composite molded lens, a press-formed lens body is integral with an injection-molded lens frame. The lens body has a lens portion and a flange portion surrounding the lens portion. Eight projections are radially formed on a top surface of the flange portion. The height of the projection increases toward an outer peripheral edge side of the flange portion. A recess is formed on an outer peripheral edge face of the flange portion and located at a position on a line extending from the projection. The recess increases torsional resilience of a joint surface between the lens body and the lens frame and strengthens bonding force there between.

主权项

1. A composite molded lens comprising a press-formed lens body and an injection-molded lens frame, the lens body having a lens portion and a flange portion surrounding the lens portion, the lens frame being integral with the lens body such that the lens frame surrounds the flange portion, the composite molded lens comprising:
at least one of projections and grooves on at least one of surfaces of the flange portion, the projections and the grooves extending radially toward an outer peripheral edge, a height of the projection increasing toward an outer peripheral edge side and a depth of the groove increasing toward the outer peripheral edge side and thereby a recess or a protrusion being formed in a portion on an outer peripheral end face of the flange portion and located on a line extending from the projection or the groove.
