| 摘要 |
The invention relates to an illumination device (1), comprising an optoelectronic component (20), with a housing body (203) and at least one semiconductor chip (3), provided for generation of radiation and a separate optical element (2), provided for fixing to the optoelectronic component with an optical axis. The optical element comprises a radiation exit surface (4) and the radiation exit surface has a concave curved partial region (5) and a convex curved partial region (7), at least partly enclosing the concave curved partial region, at a separation from the optical axis, whereby the optical axis (6) runs trough the concave curved partial region. |
