Title (EN) FLEXIBLE SUBSTRATE MOUNTED SOLID-STATE LIGHT SOURCES FOR EXTERIOR VEHICULAR LIGHTING
(FR) SOURCES LUMINEUSES A SEMICONDUCTEURS MONTEES SUR SUBSTRAT FLEXIBLE POUR L'ECLAIRAGE EXTERIEUR D'UN VEHICULE
Abstract:
(EN) Exterior lighting assemblies for use on vehicles include a flexible substrate on which are mounted a plurality of solid-state light emitting devices (34) that are preferably light emitting diodes (LEDs), although other types of devices can alternatively be employed. The light emitting devices are connected to flexible conductive traces on the flexible substrate, and leads connect the traces to a power supply on the vehicle so that electrical current can be selectively supplied to energize the light emitting devices. The flexible substrate is adapted to be mounted on the exterior surface of a vehicle, for example, as a tail lamp assembly (30), or as a headlamp, and to conform around a curved exterior surface (22). Devices that emit differently colored light can be used for indicating braking, turn direction, or to illuminate a surface over which the vehicle is travelling. A flexible optically transparent cover protects the light emitting devices.
(FR) L'invention concerne un ensemble d'éclairage extérieur pour véhicules, comprenant un substrat flexible sur lequel est montée une pluralité de dispositifs (34) lumineux à semiconducteurs, de préférence des diodes électroluminescentes (DEL), d'autres types de dispositifs pouvant être utilisés le cas échéant. Ces dispositifs lumineux sont connectés à des conducteurs flexibles sur le substrat flexible, des fils de connexion reliant ces conducteurs à une source de courant sur le véhicule, de sorte que le courant électrique peut être fourni sélectivement pour alimenter les dispositifs lumineux. Le substrat flexible est conçu pour être monté sur la surface extérieure du véhicule, par exemple, comme ensemble de feux arrière (30) ou comme projecteur, et pour s'adapter aux lignes courbes de ladite surface extérieure (22). On peut utiliser des dispositifs lumineux de couleurs différentes pour indiquer le freinage, le changement de direction ou pour éclairer la surface sur laquelle le véhicule évolue. Lesdits dispositifs lumineux sont protégés par un couvercle transparent et flexible.
