| 摘要 |
The present invention relates to an optical lens package, said lens package (1) having a lens body comprising a base (7), a central surface section (4) opposite to the base (7) and a peripheral surface section extending between the central surface section (4) and the base (7). The central surface section (4) is centered with respect to the optical axis (5) of the lens package (1) and has a convex shape in at least a first cross-sectional plane including the optical axis (5). At least a portion (6) of the peripheral surface section has a concave shape in said first cross-sectional plane. With such a design of the optical lens package (1) in addition to a central collimated light bundle with high luminous flux also side visibility is achieved by means of the concave portion (6) up to a high angle with respect to the optical axis (5). This side visibility is achieved without additional optics thus lowering the production costs of such an optical system compared to a solution using additional optics. |
