Abstract

Selon l'invention, une lentille à structure modifiable (1) est formée sur une source lumineuse DEL (2) de manière à agir afin de focaliser la lumière dans une configuration appropriée (sens de rayonnement) et d'extraire simultanément de la chaleur à partir des surfaces supérieure et latérale de la puce (2) de DEL. Ladite source lumineuse DEL (2) est montée sur un corps de dissipateur thermique arrière (4). Ladite lentille (1) comprend une région primaire (5) immédiatement adjacente à la source DEL (2) (et au sein de laquelle est intégrée ladite source DEL (2)). Cette région primaire comprend une matière particulaire de composé de diamant répartie dans une matrice de gel flexible, comme indiqué ci-après de manière détaillée dans la description. Une couche de superposition (6) constituée d'une matière transparente à la lumière n'est pas imprégnée de la matière de composé de diamant.
