Abstract (en)
A vehicle lighting device (1), typically a headlamp or signal lamp, including a casing (2); a light source (3) and a reflector (4) housed inside the casing; and a transparent cover (5) closing the casing and positioned opposite the light source. The reflector is defined by a ring (20) made of material pervious to light, and constituting an internal-reflection lens. And the ring is bounded by a front surface (21) facing the transparent cover and located inside the casing, on the opposite side to the light source; by an inner lateral surface (22), e.g. defining a geometrical figure of revolution having an axis of symmetry (A) defining an optical axis of the lighting device, along which the light source is located; and by an outer lateral surface (23) which is concentric with the inner lateral surface, defines with the inner lateral surface an interface bounding the internal-reflection lens defined by the ring, and includes at least one inclined surface (24) forming such an angle with the optical axis that the light rays inside the internal-reflection lens defined by the ring (20) are reflected totally onto the front surface (21). <IMAGE>
