Abstract

The use of white or color tunable LEDs (light-emitting diodes), which can replace a large light source apparatus and light-guiding fiber bundle, enable the miniaturization of the whole endoscope system and remove constraints on the design of its shape. We have developed a novel white LED for a new experimental prototype LED-illuminated gastrointestinal endoscope having the color rendering in the clinically important red range at around 600 nm.
