Abstract

Dispositif lumineux comprenant :- un support flexible (1) ;- au moins une puce LED (2) disposée sur une surface principale du support (10) ; et- une couche d’encapsulation (6) recouvrant la puce LED (2) et laissant passer tout ou partie de la lumière générée par la puce LED (2).La couche d’encapsulation (6) présente une surface texturée (7) comprenant une pluralité de reliefs formés d’excroissances et de creux. Figure pour l’abrégé : Fig 2A luminous device comprising:- a flexible support (1);- at least one LED chip (2) arranged on a main surface of the support (10); and- an encapsulation layer (6) covering the LED chip (2) and passing all or part of the light generated by the LED chip (2).The encapsulation layer (6) has a textured surface (7) comprising a plurality of reliefs formed of protrusions and hollows. Figure for the abstract: Fig 2
