Abstract

A lighting device (10), in particular for use in a dental lamp, characterised in that it comprises one or more optical groups, each of which comprises an LED light source (11), a collimation group (12) and a reflector (13), the collimation groups (12) being arranged close to the respective LED light sources (11) and converging the light radiation coming from them in respective cones, the vertices of which are located close to a common point, which defines the first focus of an ellipsoid, and which intersect the surface of the ellipsoid defining respective areas, at which the respective reflectors (13) are arranged, the surfaces of which come near to that of said ellipsoid.
