Abstract
A device is for a lighting/signaling assembly of an automotive vehicle. The assembly includes a substantially transparent optical material and at least one light source of an 'LED' type arranged for emitting light rays propagating within a thickness of the optical material. The device comprises a plate of substantially transparent optical material forming a screen and including at least one substantially bilateral elongated bulge defining a substantially circular overall substantially perpendicular cross-section and substantially mean longitudinal axis in a substantially mid-plane of the bulge and being adapted to form a light guide. At least one LED is disposed at at least one end of the light guide and defines a main axis of the LED that is substantially orthogonal to a substantially longitudinal axis of the light guide.
