Abstract

L’invention concerne un guide de lumière de type plat pour module lumineux de signalisation (400) destiné à être hébergé dans le boîtier (100) d’un bloc optique d’éclairage et/ou de signalisation de véhicule automobile, ledit guide de lumière comportant un corps translucide sensiblement plat (440) comprenant au moins une surface d’entrée (443) prévue pour recevoir les rayons lumineux émis par au moins une source de lumière (410) et apte à les guider jusqu’à une face de sortie (445) distante de ladite surface d’entrée (443) ; caractérisé en ce que ledit guide de lumière comporte également un corps opaque (450) venu de moulage d’une seule pièce avec ledit corps translucide (440) par multi-injection de polymères thermoplastiques et comprenant des moyens de fixation (454, 456) pour assujettir rigidement ce guide audit boîtier (100) et à d’autres éléments logés dans ce dernier. Figure à publier avec l’abrégé : Fig. 2The invention relates to a flat-type light guide for a signaling light module (400) intended to be housed in the housing (100) of a motor vehicle lighting and/or signaling optical unit, said light guide comprising a substantially flat translucent body (440) comprising at least one input surface (443) provided to receive the light rays emitted by at least one light source (410) and capable of guiding them as far as an output face ( 445) remote from said entry surface (443); characterized in that said light guide also comprises an opaque body (450) molded in one piece with said translucent body (440) by multiple injection of thermoplastic polymers and comprising fastening means (454, 456) for rigidly attaching this guide to said housing (100) and to other elements housed in the latter. Figure to be published with abstract: Fig. 2
