摘要

The device has a fiber bundle (4) comprising a plane input face (40) corresponding to a common part regrouping optical fibers enlightened by an LED (2) whose source surface is small. An optical adaptation device (3) is disposed between the LED and the input face of the bundle. The device comprises two conical parts and an output face (31) disposed against the input face. The device has an input face (30) disposed against the LED comprising a cavity with a shape complementary to the shape of the LED.
