For the fundus camera illumination device, fundus camera and fundus camera for collector

摘要

This invention relates to a lighting device comprising a condenser which is operably linked to a light source comprising a plurality of LED elements. The collector, the first surface being formed to receive the optical radiation emitted from the light source the light incident portion (5) and (51), a light emitting portion (6) of propagation of a light beam having a ring-shaped It consists of a solid transparent body having a second surface formed to, a plurality of protrusions protruding from the first surface in the light incident portion (7), wherein the protrusion light coming from the light source a plurality of reflecting surfaces of the optical radiation that acts as a collimating lens of the radiation was received from the light incident portion (8, 9), and the projecting portion, and the reflective surface, a light emitting portion and the light incident portions During, to propagate the optical radiation coming from the light source along the predetermined optical path extending inside of the transparent body, and is disposed to one another.
