Title
(EN) LUMINOUS ELEMENT, AND DISPLAY DEVICE AND LIGHTING DEVICE USING IT
(FR) ELEMENT LUMINEUX, DISPOSITIF D'AFFICHAGE ET DISPOSITIF D'ECLAIRAGE METTANT CET ELEMENT EN APPLICATION
Abstract
(EN)
A luminous element which has a laminate structure provided with at least a luminous layer with a luminous area and a reflection layer for reflecting light emitted from the luminous area, and which picks up light, emitted from the luminous area, from a light pick-up surface separated from the luminous area, characterized in that a light scattering unit is present at part of the reflection layer.
(FR)
Elément lumineux possédant une structure stratifiée pourvue d'au moins une couche lumineuse possédant une zone lumineuse et d'une couche réfléchissante servant à réfléchir la lumière émise par la zone lumineuse, cet élément lumineux captant la lumière émise par la zone lumineuse depuis une surface de captage de lumière séparée de la zone lumineuse, une unité de diffusion de lumière étant située au niveau d'une partie de la couche réfléchissante.
