    摘要: The present invention relates to a light integrating device (10) comprising a solid light integrating device (1) with a first length (L1) and with coupled in abutment thereto by an optical coupling a hollow light integrating device (2) such that the light integrating device (10) has a second length (L2) larger than the first length (L1). The difference between the second length and the first length is in the range of 5 mm to 10 mm. No obstructions such as dirt or dust can attach to the end surface of the light integrating system (10) because the end surface is formed by a virtual surface, i.e. a surface which is not physically present. The light integrating system (10) according to the present invention may be used in projection systems, in lighting systems or in illumination systems. The present invention furthermore provides a method for generating a shaped and uniform light spot.
