Battery-powered light source arrangement for endoscope

摘要

A light source arrangement for a battery-powered light source unit of an endoscope comprises an optically transparent base board, a single light emitting element such as a bare LED arranged at the center of and in close proximity to the back of the transparent base board or a plurality of light emitting elements such as bare LEDs arranged in close proximity to the back of the transparent base board at regular angular intervals and regular distances from the center of the transparent base board, and a reflector disposed behind the transparent base board so as to reflect light emanating backward from the light emitting element or elements toward the transparent base board.
