| 摘要 |
The invention relates to an optical attachment (10) for a light source, especially for a light-emitting diode (12), comprising an inner lens area (14) which surrounds the optical axis (13) of said attachment (10) and is designed for inner light rays (15) emitted by the light source, and an outer reflector area (16) which surrounds the inner lens area (14) in a ring-shaped manner and is designed for outer light rays (17) emitted by the light source. The combination of refraction in the inner lens area and reflection in the outer reflector area allows for the dimensions of the optical attachment to be kept relatively small. It further makes it possible to capture more light than a lens or a reflector and for the point-shaped light-emitting diode on the output side to appear as a large luminous surface. |
