Abstract
Lighting device (10) having a support (11), a plurality of emitting elements (12) adapted to emit light, fixed to the support (11) and each having an emission direction (A) radial to a predefined optical axis (B). The lighting device (10) is provided with a reflection surface (13) facing the emitting elements (12) and configured to reflect the light emitted in use by the latters in a direction parallel to the optical axis (B).
Claims9
Lighting device (10) for a fundus camera, said lighting device (10) 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), said emission direction (A) consisting of the median direction of a light beam which is irradiated in use by the emitting element (12) wherein 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 said emitting elements (12) adapted to emit light, in a direction parallel to said optical axis (B);
- characterised in that said 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).
