Abstract
Un dispositif d'éclairage à diode électroluminescente à éclairage fortement uniforme comprend une source électroluminescente (10), une protection à modulation de lumière (20), une protection de réflexion (40) et un objectif de focalisation variable (30) placés en face de la source électroluminescente (10). La lumière en provenance de la source (10) est d'abord modulée par la protection (20) dont la forme peut-être soit un cône oblique (21), soit une parabole (22), soit une ellipse (23), pour être ensuite réfléchi par la protection (40) dont la configuration est soit un cylindre (41), soit une parabole (42), soit un cône (43) avant d'être finalement projetée vers l'extérieur à travers l'objectif (30).
