Abstract

L'invention concerne un dispositif d'éclairage et/ou de signalisation, notamment pour véhicule automobile, comprenant au moins une source de lumière (1) et un guide de lumière (2), ladite source (1) comprenant un support (4) et une pluralité de composants (6) émetteurs de lumière, disposés sur ledit support (4) de façon à émettre un faisceau lumineux, ledit dispositif étant configuré pour diriger ledit faisceau vers ledit guide (2), dans lequel ledit support (4) est un circuit imprimé et/ou lesdits composants (6) émetteurs de lumière sont des diodes électroluminescentes, dans lequel lesdits composants (6) émetteurs de lumière sont disposés de façon à définir une surface d'émission (10) dudit faisceau lumineux sur une face (12) dudit support (4), dans lequel ladite source de lumière (1) est configurée de façon à ce que ladite surface d'émission (10) présente un axe d'extension longitudinale, dans lequel ledit guide de lumière (2) comprend au moins une portion émettrice (20), configurée pour émettre de la lumière en dehors dudit guide (2), et au moins une portion de guidage (22), située entre ladite source (1) et ladite portion émettrice (20), configurée pour transmettre ledit faisceau lumineux de ladite source (1) à ladite portion émettrice (20).The invention relates to a lighting and / or signaling device, in particular for a motor vehicle, comprising at least one light source (1) and a light guide (2), said source (1) comprising a support (4) and a plurality of light emitting components (6) disposed on said support (4) to emit a light beam, said device being configured to direct said beam toward said guide (2), wherein said support (4) is a printed circuit and / or said light-emitting components (6) are light-emitting diodes, wherein said light-emitting components (6) are arranged to define an emission surface (10) of said light beam on one side ( 12) of said carrier (4), wherein said light source (1) is configured such that said transmitting surface (10) has a longitudinal extension axis, wherein said light guide (2) comprises at least one port an emitter ion (20), configured to emit light outside said guide (2), and at least one guide portion (22), located between said source (1) and said emitter portion (20), configured to transmit said light beam from said source (1) to said emitting portion (20).

Selon l'invention, ladite portion de guidage (22) présente une section plus faible que celle de ladite portion émettrice (20).

Figure imgaf001
According to the invention, said guide portion (22) has a smaller section than that of said emitting portion (20).
