Abstract

L'invention concerne un dispositif d'éclairage surfacique (10), en particulier pour une utilisation dans un vêtement (30). Le dispositif d'éclairage surfacique (10) présente une couche de recouvrement (11) pourvue d'une surface (12) de sortie de lumière. Une couche de réflexion (13) présentant une surface de réflexion (14) est disposée sur le côté opposé à la couche de recouvrement (11). Une première couche de dispersion (15) en matériau textile, de préférence une structure plane textile, est immédiatement adjacente à la couche de recouvrement (11). La surface plane textiles peut être assemblée de manière plane avec la couche de recouvrement ou être placée contre celle-ci. Une ou plusieurs rangées de moyens d'éclairage (16) sont disposées à une certaine distance l'une de l'autre dans une direction longitudinale L. Les moyens d'éclairage (16) présentent un côté de sortie (17) de lumière, qui est tourné vers la couche de réflexion (13). Un écarteur (19) assure une distance minimale entre les moyens d'éclairage (16) et la couche de réflexion (13). La lumière émise par les moyens d'éclairage (16) est réfléchie sur la couche de réflexion (13) vers la couche de recouvrement (11). De ce fait, le parcours de lumière dans le dispositif d'éclairage surfacique (10) peut être agrandi, sans agrandir l'épaisseur du dispositif d'éclairage surfacique (10) perpendiculairement à la surface (12) de sortie de lumière.
