Title (EN) LIGHTING FOR AUDIO DEVICES
(FR) ÉCLAIRAGE POUR DISPOSITIFS AUDIO
Abstract:
(EN) An apparatus may include an inner module, an outer module that substantially surrounds a perimeter of the inner module, a plurality of light emitters, and a light distribution medium. The plurality of light emitters may be positioned under the inner module and project light radially outward. The light distribution medium may transport the light projected from the plurality of light emitters to an edge of the light distribution medium. The edge may include a diffusive surface and traverse a substantial portion of a boundary between the inner module and the outer module.
(FR) L'invention concerne un appareil pouvant comprendre un module intérieur, un module extérieur qui entoure sensiblement un périmètre du module intérieur, une pluralité d'émetteurs de lumière et un milieu de répartition de la lumière. La pluralité d'émetteurs de lumière peut être positionnée sous le module intérieur et projeter radialement de la lumière vers l'extérieur. Le milieu de répartition de la lumière peut transporter la lumière projetée à partir de la pluralité d'émetteurs de lumière jusqu'à un bord du milieu de répartition de la lumière. Le bord peut comprendre une surface diffusive et parcourir une proportion substantielle d'une frontière entre le module intérieur et le module extérieur.
