Title
(EN) LIGHT EMITTING SHEET
(FR) FEUILLE ÉMETTRICE DE LUMIÈRE
Abstract
(EN)
A lighting system comprises a light guide comprising a sheet of light guiding material and an array of light out-coupling structures formed as a regular pattern at a surface of the sheet of light guiding material. At least one LED module is mounted on said surface of the sheet of light guiding material for directing light into the sheet.
(FR)
L'invention concerne un système d'éclairage comprenant un guide de lumière incluant une feuille en matériau de guidage de la lumière et un réseau de structures de découplage de la lumière formées selon un motif régulier sur une surface de la feuille en matériau de guidage de la lumière. Au moins un module à LED est monté sur ladite surface de la feuille en matériau de guidage de la lumière pour diriger la lumière dans la feuille.
