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 aligned along an optical axis of the light source where the central lens comprises a central entrance surface and a central exit surface. The light collector also has a peripheral lens part surrounding at least of part of the central lens. The peripheral lens comprises a that said central lens and said peripheral lens is mutual adapted to convert said light emitted by said light source into a common light beam having a substantial circular and rotationally symmetric cross sectional light distribution, where said common light beam comprises said first light beam part and said second light beam part.
