摘要	A device for optically coupling a light emitting diode and a radiation pickup such as an optical fiber. The light emitting diode element includes at least one emissive section within an active layer where a part of the light irradiation does not emerge from the diode element if it is emitted at an excessive angle of incidence. A lenticular element in the form of either a semi-cylindrical lens or a semi-toroidal lens is associated with the emissive section. In one form, the device includes a circular central lens and a plurality of semi-toroidal lens concentric with respect to the central lens and associated with annular emissive sections.
其他摘要	一种用于光学耦合发光二极管和辐射拾取器（例如光纤）的装置。发光二极管元件包括在有源层内的至少一个发光部分，其中如果以过大的入射角发射，则部分光照射不会从二极管元件中出现。半圆柱透镜或半环形透镜形式的透镜元件与发光部分相关联。在一种形式中，该装置包括圆形中心透镜和多个半环形透镜，所述多个半环形透镜相对于中心透镜同心并与环形发射部分相关联。
