LED lighting device, in particular a catadioptric spotlight

摘要

A LED lighting device (1) extending substantially along an axis (A) and having a LED light source (3); a light guide (13) located in front of the light source (3) and extending between a proximal end (16) substantially facing the light source (3), and a distal end (17) opposite the proximal end (16); and an optical system (5) associated with the light source (3) to direct the luminous flux emitted by the light source (3); the light guide (13) being shaped so as to generate at the distal end (17) of the light guide (13) an emissive surface equivalent to the real emitting surface of the light source (3) at a predetermined position with respect to the optical system (5).
