Title
(EN) LIGHTING DEVICE WITH AN OPTICAL ELEMENT HAVING A FLUID PASSAGE
(FR) DISPOSITIF D'ÉCLAIRAGE ÉQUIPÉ D'UN ÉLÉMENT OPTIQUE PRÉSENTANT UN PASSAGE DE FLUIDE
Abstract
(EN) A lighting device (1) comprises at least one light source (3) and at least one optical element (5). The optical element (5) may be arranged to transmit light emitted by the light source (3). The optical element (5) comprises a light transmissive material (7) and at least one passage (9) extending through the light transmissive material (7) for allowing a flow of fluid through said optical element (5). The passage (9) is arranged such that a major portion of the light(16)emitted by said light source (3) entering the passage (9) further propagates through the light transmissive material (7).The optical element (5) comprises a plurality of layers (18) of the light transmissive material (7) spaced apart from each other, each layer comprising at least one through-hole (11).
(FR) L'invention porte sur un dispositif d'éclairage (1) qui comprend au moins une source lumineuse (3) et au moins un élément optique (5). L'élément optique (5) peut être agencé pour transmettre la lumière émise par la source lumineuse (3). L'élément optique (5) comprend une matière transmettant la lumière (7) et au moins un passage (9) qui s'étend à travers la matière transmettant la lumière (7) pour permettre de faire circuler un flux de fluide à travers ledit élément optique (5). Le passage (9) est agencé de telle sorte que la majeure partie de la lumière (16) émise par ladite source de lumière (3) et qui entre dans le passage (9) se propage plus loin à travers la matière transmettant la lumière (7). L'élément optique (5) comprend une pluralité de couches (18) de la matière transmettant la lumière (7) espacées l'une de l'autre, chaque couche comprenant au moins un trou traversant (11).
