Luminous signalling device for an automobile

摘要

The device (12) has two light sources (14A, 14B) i.e. LEDs, that are activated in an alternative or grouped manner. Formation units are constituted of facets (36) and optical elements (20A, 20B) with collecting surfaces (22) to form intermediate light beams that are directed towards a common output surface of a transversal refraction face (42). The face has a series of prisms, where each prism has two facets (44A, 44B) respectively refracting the beams to form two light signaling beams to obtain stop light and turn signal indicator light functions.
