Optical device for lighting or signalisation, in particular for a vehicle

The device has a light guide (3) for guiding a part of light emitted by a light source (2) i.e. radial radiation LED. The light guide has a reflection surface (6) for reflecting the light propagated in the guide towards an output surface (5). The light guide is in cylindrical ply shape and made by m...

Beschreibung
Zusammenfassung:	The device has a light guide (3) for guiding a part of light emitted by a light source (2) i.e. radial radiation LED. The light guide has a reflection surface (6) for reflecting the light propagated in the guide towards an output surface (5). The light guide is in cylindrical ply shape and made by molding a plastic material. The light guide is arranged such that the light beam issued from the output surface is parallel to an optical axis of the device. An independent claim is also included for a method for fabricating a light guide.
