摘要： A primary optic for a light-emitting diode or device (LED) includes a tilted wedge atop a truncated compound parabolic concentrator (CPC). The CPC includes an input face and a lower exterior surface defined by a tilted parabolic segment rotated about an axis. The bottom end of the lower exterior surface joins the perimeter of the input face. The tilted wedge includes an upper exterior surface above the lower exterior surface, and an interior conical surface surrounded by the lower and the upper exterior surfaces. The upper exterior surface is defined by a tilted straight line rotated about the axis. The interior conical surface is defined by a smooth curve rotated about the axis. The interior conical surface has a vertex located at the axis and within the lower exterior surface. The top ends of the interior conical surface and the upper exterior surface join to define an output aperture.

摘要： The present invention relates to an optical device (229) for forming a light beam, which optical device comprises a lens (330) having a top section (331) configured to receive light emitted by a light source (220), a bottom section (332) configured to allow the received light to exit the lens, and a plurality of side sections (333) stretching from the top section to the bottom section. The plurality of side sections enclose the lens and are adapted to reflect and refract incident rays of the received light. A cross-section (334) of the lens, in a plane perpendicular to a centre axis (338) stretching from the top section to the bottom section, has the shape of a polygon, which polygon is oriented in a lengthwise direction (335) and in a transversal direction (336) being perpendicular to each other. Furthermore, the lens is adapted such that the received light exits the lens as a light beam formed to an elongated shape (5) at a predetermined distance (4) from the optical device. With the presented optical device, a compact lens enabling for a desired elongated illumination distribution is provided.
