The lighting system for an automotive vehicle has uses smooth conic section solids to form a beam pattern. In one aspect of the invention the A/C ratio of the conic section solids are varied to collimate the light emitted in the vertical direction and spread light in the horizontal direction. In another aspect of the invention the A/C ratio of a hyperbolic conic section may remain the same while adding fluting to the outer surface of the lens to provide beam redirection.

A light guide body includes a first rod-like light guide portion and second rod-like light guide portions which are spaced from the first rod-like light guide portion in the vertical direction and plate-like light guide portions which are disposed so as to link their circumferential surfaces. Light that reaches the first rod-like light guide portion via the plate-like light guide portions after being emitted from light sources and entering the second rod-like light guide portions is emitted forward of the lamp from the circumferential surface of the first rod-like light guide portion.

A motor vehicle lighting device is proposed, having a light source, and having an optical waveguide, which has a coupling lens, which has at least one reflector, wherein the optical waveguide has first and second planes that are perpendicular to one another, and intersect, and wherein the lines of intersection are each defined by a light beam emitted from the reflector. The device is distinguished in that a transformation by the coupling lens occurs such that an aperture angle of propagation directions of the light beams lying in the second planes is reduced, and the aperture angle of propagation directions lying in the first planes is not altered, or is altered less strongly, and in that the optical waveguide has a transport and transformation lens, wherein the coupling lens and the transport and deflection lens are separate components.

A signal lamp comprises at least one light source arranged at the entry of a longitudinal light guide oriented with its longitudinal axis (γ) in the direction (s) of light exit from the lamp, and at least a portion of the light from the light source passes into a transversal light guide oriented with its longitudinal axis (α, β) transversally to longitudinal axis (γ). Transversal light guide is fitted on a part of its casing with an exit surface for light to exit from the lamp. Longitudinal light guide is fitted with at least two reflective surfaces that do not overlap when viewed in the direction of longitudinal axis (γ), and that are inclined towards axis (γ) to reflect light beams to at least two transversal light guides having their entries against the reflective surfaces, and their exit surfaces at a distance from each other in direction (s).

An automotive LED lamp having a light guide (28) having a single central bore (29) defined by a cylindrical wall (26) and an outer surface (31) defined by a plurality of outer wall segments (35) bounding, as seen in cross-section transverse the optical axis (18) a regular polygonal shape having more than four sides. The outer polygonal shape has between five sides and sixteen sides, preferably a ten-sided decagon.

An apparatus for producing light signals in a vehicle. The same physical apparatus produces light signals of two different colors. Light emitting diodes (LEDs) of two different colors produce diverging light rays. These rays are captured by a transparent plate and conducted to an edge of the plate, which reflects and collimates the light into parallel beams. The parallel beams then reach an elongated lens running along another edge of the plate, which focuses, or de-focuses, the light and transmits it externally as a signal.

A stoplight for a vehicle includes a light source, a core portion formed of a transparent material and an integral cladding portion formed of a material having a refractive index which is smaller than that of the core portion. The core portion includes a bundle portion which is connected to the light source and a plurality of branch portions which diverge from the bundle portion. The cladding portion covers the core portion.
