Disclosed is a lighting fixture comprising at least three light functions, said lighting fixture being a trifunctional projector. In particular, a vehicle headlight is disclosed, which has in addition to a dipped beam and a main beam a daytime running light and/or a position light as a further light function.
1. A luminaire comprising:
at least one first light source, the light from which is substantially emittable to a reflector and is deflectable by the latter to an optical intermediate plane as a result of which a first light function is realized;
a second light source, the light from which is guidable via an optical waveguide to the optical intermediate plane as a result of which a second light function is realized;
a further light source, the light from which is guidable via a drum lens to the optical intermediate plane as a result of which a third light function is realized; and
a collimation lens connected with the drum lens via at least one web provided between the collimation lens and the drum lens.
2. The luminaire as claimed in claim 1 , wherein the light from the further light source is guidable via the optical waveguide to the optical intermediate plane.
3. The luminaire as claimed in claim 1 , wherein a reflective coating is arranged on a side of the optical waveguide facing the reflector.
4. The luminaire as claimed in claim 1 , wherein the first light source is secured on a first printed circuit board, which is arranged on a side of the optical waveguide facing the reflector.
5. The luminaire as claimed in claim 1 , wherein the second light source and the further light source are secured on a second printed circuit board, which is aligned approximately parallel to the optical intermediate plane.
6. The luminaire as claimed in claim 1 , wherein the collimation lens is arranged between the first light source and the optical waveguide, and wherein the optical waveguide extends from the collimation lens to the optical intermediate plane.
7. The luminaire as claimed in claim 1 , wherein the luminaire is a vehicle headlight, the first light function of which is a low-beam light, and the second light function of which is a high-beam light, and the third light function of which is a daytime running light or a position light.
8. The luminaire as claimed in claim 4 , wherein an auxiliary light source is secured on the first printed circuit board, the light from which auxiliary light source is substantially emittable to the reflector and is deflectable by the latter to the optical intermediate plane as a result of which a fourth light function is realized.
9. The luminaire as claimed in claim 8 , wherein the luminaire is a vehicle headlight, the first light function of which is a low-beam light, and the second light function of which is a high-beam light, and the third light function of which is a daytime running light, and the fourth light function of which is a position light.
