Abstract
A branched type light transmission system including a plurality of light transmission tubes each comprising a flexible cylindrical cladding and a transparent core filled in the cladding and which has a higher index of refraction than the cladding. The core is made of an elastically deformable solid substance, and the plurality of light transmission tubes are bundled together at the light-incident ends thereof with a binding member and thus applied with an external pressure to deform each light transmission tube in order to minimize the clearance between the light transmission tubes.
