| 摘要 |
The present invention relates to an illumination device comprising an light source and a light guide coupled thereto, preferably a liquid light guide, the light exit end of which is provided in the form of a light diffuser, said light diffuser comprising a polymer, preferably a fluorocarbon polymer. The scattering effect of the diffuser is obtained because of its crystalline structure or by fluorescent additives in the polymer. The crystallinity may be inherent to the internal structure of the polymer itself and/or be created or varied by compounding the polymer with other materials. The diffuser is welded to the sheathing tube of the liquid light guide simultaneously providing the seal for the liquid at the distal end of the liquid light guide. A preferred use of the illumination device is photodynamic diagnostics and therapy in the field of medicine.
