LIGHT COLLECTOR WITH COMPLEMENTING ROTATIONALLY ASYMMETRIC CENTRAL AND PERIPHERAL LENSES

摘要

The present invention relates to a light collector for collecting light emitted by a light source and converting the collected light into a light beam, The light collector comprises a central lens part (219) aligned along an optical axis (215) of the light source where the central lens comprises a central entrance surface (303) and a central exit surface (305). The light collector also has a peripheral lens part (221) surrounding at least a part of the central lens. The lens parts are rotationally asymmetric in relation to the optical axis, thereby distorting the emitted light. Said central and peripheral lenses are mutually adapted to convert said light (215) emitted by said light source into a common light beam having a substantially circular and rotationally asymmetric cross sectional light distribution, where said common light beam comprises said first light beam part (223) and second light beam part (225).
