Light guide for an optical device, notably for lighting and/or signaling

摘要

A light guide for an optical device, notably for lighting and/or signaling, comprising:
at least one light output portion having a top face and a bottom face linked together by a light output rim,at least one collimation subassembly suitable for receiving light emitted by a light source and for directing at least a part of this light toward the light output portion, the collimation subassembly having a top face and a bottom face linked together by a rim, anda coupling portion coupling the light output portion to the subassembly, the coupling portion having a top face and a bottom face,the bottom and top faces of the collimation subassembly extend substantially in mutually parallel planes, and in that the top face of the coupling portion and at least one of the top face of the collimation subassembly and of the top face of the light output portion meet at an edge.

1. A light guide for an optical device, notably for lighting and/or signaling, comprising:
at least one light output portion having a top face and a bottom face linked together by a light output rim, at least one collimation subassembly suitable for receiving light emitted by a light source and for directing at least a part of this light toward the light output portion, the collimation subassembly having a top face and a bottom face linked together by a collimation rim, and a coupling portion coupling the light output portion to the subassembly, the coupling portion having a coupling portion top face and a coupling portion bottom face, wherein the bottom and top faces of the collimation subassembly extend substantially in mutually parallel planes, and in that the coupling portion top face of the coupling portion and at least one of the top face of the collimation subassembly and of the top face of the light output portion meet at an edge; wherein said collimation rim is at least partially curved or arcuate and said coupling portion facilitates enhancing a uniform distribution of light through said light output rim, wherein the guide further comprises: a plurality of collimation subassemblies, a single light output portion, and a plurality of coupling portions, each coupling portion coupling one of the collimation subassemblies to the light output portion.
