Abstract

L'invention concerne un dispositif de rayonnement optique comprenant une grappe de diodes électroluminescentes (11, 43) montées de sorte que des facettes profilées de diodes électroluminescentes contiguës soient réunies de manière à augmenter la compacité des diodes électroluminescentes dans la grappe. Un guide optique (41) recueille la lumière émise par les diodes électroluminescentes. Deux ou plusieurs guides optiques (41) et grappes de diodes électroluminescentes (43) peuvent être montés en série pour produire un faisceau lumineux unique. Un conduit de chaleur (45) permet d'évacuer la chaleur des diodes électroluminescentes (43). Le conduit de chaleur (56) peut être annulaire et contient un espace de stockage intérieur pour batteries (60) ou analogues.
