Abstract
A motor vehicle taillight (10) has at least a rear position light function, a turn signal light function, and a brake light function. The rear position light function and the turn signal light function are formed by a common first optical waveguide (15) and by first LED light sources (16, 17) that inject light into the first optical waveguide (15). The brake light function is formed by at least two second optical waveguides (23) and by second LED light sources (24) that inject light into the optical waveguides (23). The second optical waveguides (23) border the first optical waveguide (15) on at least two sides.
Claims10
A motor vehicle taillight having at least a rear position light function, a turn signal light function and a brake light function, comprising:
- a first optical waveguide and first LED light sources that inject light into the first optical waveguide to carry out the rear position light function and the turn signal light function;
- and
- at least two second optical waveguides and second light sources that inject light into the second optical waveguides to carry out the brake light function, the second optical waveguides bordering the first optical waveguide on at least two sides, wherein
- the first optical waveguide has a T-shape cross-section with two vertical limbs formed respectively with coupling-in optical surfaces for coupling in light and a horizontal limb with a coupling-out optical end, two total internal reflection surface formed in transition portions between the vertical limbs and the horizontal limb to redirect the light that is coupled into the vertical limbs into the horizontally extending limb.
A motor vehicle taillight having at least a rear position light function, a turn signal light function and a brake light function, comprising:
- a first optical waveguide and first LED light sources that inject light into the first optical waveguide to carry out the rear position light function and the turn signal light function;
- at least two second optical waveguides and second light sources that inject light into the second optical waveguides to carry out the brake light function, the second optical waveguides bordering the first optical waveguide on at least two sides;
- and
- a cover plate through which light of the first and second optical waveguides exits, the second optical waveguides projecting light into a top and bottom covering segments of the cover plate, and the first optical waveguide projecting light into a central covering segment of the cover plate between the top and bottom covering segments.
