1. Lighting device (10) for fundus camera comprising a support (11) and a plurality of emitting elements (12) adapted to emit light, each having an emission direction (A) and fixed to said support (11), characterised in that each emission direction (A) of said emitting elements (12) is radial with respect to a predefined optical axis (B), said lighting device (10) being provided with a reflection surface (13) facing said emitting elements (12) and configured to reflect the light, which is emitted in use by the latters, in a direction parallel to said optical axis (B); wherein the lighting device (10) comprises a light guide (17) having:
a. an input surface (17a), annular to said optical axis (B) and facing said emitting elements (12); b. an emission surface (17b) annular to said optical axis (B) and configured to direct light parallel to said optical axis (B); and c. an internal wall (17c), frusto-conical and annular to said optical axis (B) and defining said reflection surface (13). |
