Abstract
The present invention relates to an optical device () for forming a light beam, which optical device comprises a lens () having a top section () configured to receive light emitted by a light source (), a bottom section () configured to allow the received light to exit the lens, and a plurality of side sections () 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 () of the lens, in a plane perpendicular to a center axis () stretching from the top section to the bottom section, has the shape of a polygon, which polygon is oriented in a length-wise direction () and in a transversal direction () 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 () at a predetermined distance () from the optical device. With the presented optical device, a compact lens enabling for a desired elongated illumination distribution is provided.
