摘要
A semiconductor-based light source device for an endoscope that provides for an even power distribution and/or color distribution of light. The semiconductor-based light source device includes a plurality of semiconductor light sources and a plurality of fiber bundles, in which the respective fiber bundles are each segregated into a plurality of fiber sub-bundles for directing substantially the same amount of illumination from a respective semiconductor light source to each of a corresponding plurality of illumination windows disposed at a distal end of the endoscope. By providing such a semiconductor-based light source device, in which the respective semiconductor light sources are operative to adjust the intensity and/or color or wavelength of the light emitted by the respective semiconductor light sources, a desired color temperature and/or color balance for illumination of tissue and/or other matter under examination by the endoscope can be achieved.
