Title (DE) LICHTLEITPLATTEN
(EN) LIGHT-DIRECTING PANELS
(FR) PLAQUES GUIDES DE LUMIERE
Abstract:
(DE) Die Erfindung betrifft Lichtleitplatten aus transparenten Kunststoffen. Dabei werden in die aus einem transparenten Kunststoff A bestehenden Platten mehrere dünne Bänder aus einem Kunststoff B eingefügt, mit der Maßgabe, daß sich A und B im Brechungsindex oder im thermischen Ausdehnungskoeffizienten unterscheiden.
(EN) The invention concerns light-directing panels made up of transparent plastic materials. The panel consists of a transparent plastic A in which several thin strips of another plastic B have been incorporated, plastic A and plastic B differing from each other in refractive index or in coefficient of thermal expansion.
(FR) L'invention concerne des plaques guides de lumière en plastique transparent. Entre les plaques constituées d'un plastique transparent A, sont insérées plusieurs bandes fines de plastique B, les plastiques A et B se distinguant par leur indice de réfraction ou leur coefficient de dilatation thermique.
