Lighting apparatus for vehicles
A lighting apparatus for vehicles with a plurality of light sources and with a defined light distribution. The optical unit has an upstream optical unit with upstream optical elements allocated to the respective light sources, which are immediately adjacent to the light sources in the primary emission direction upstream of same. The majority of upstream optical elements have a segmented embodiment and is connected by joining.
1. A lighting apparatus for vehicles comprising:
one or more light sources; and
an optical unit for generating a specified light distribution, wherein the optical unit has an upstream optical unit with upstream optical elements, each of which is assigned to a respective of said one or more light sources, the optical elements joining the light sources in the primary direction of emission upstream of said sources,
wherein the upstream optical unit has a modular configuration, where the majority of upstream optical elements are configured in selectively connectable segments,
wherein the upstream optical elements each have an upper reflector segment and a lower reflector segment, and
wherein connected upstream optical elements are separated from each other by a separator strip element.
2. The lighting apparatus in accordance with claim 1 , wherein the upstream optical elements have at least one of a substance-to-substance bond, a frictional connection or a positive fit with each other.
3. The lighting apparatus in accordance with claim 1 , wherein the upstream optical unit has at least one of a plurality of identical upstream optical elements and a number of different upstream optical elements.
4. The lighting apparatus in accordance with claim 1 , wherein the upstream optical elements each have at least one reflector segment with curved reflector surfaces and wherein the upstream optical elements have a detachable connection to each other.
5. The lighting apparatus in accordance with claim 1 , wherein the separator strip elements extend perpendicular to a light source level (E) in which the light sources are arranged and wherein a rear-facing edge of the separator strip element extends in the light source level (E) and wherein a front edge of the separator strip element is flush with one front side of the reflector segment.
6. The lighting apparatus in accordance with claim 1 , wherein the separator strip elements are each configured as reflecting metal parts.
7. The lighting apparatus in accordance with claim 4 , wherein the top reflector segment and the bottom reflector segment are shaped such that the light distribution segments generated by the upstream optical unit arranged in the primary emission direction (H) are mapped by a primary optical unit arranged upstream of the upstream optical unit to light distribution segments that are immediately adjacent in the light distribution.
8. The lighting apparatus in accordance with claim 1 , wherein the upstream optical elements are arranged in at least one of a single row and multiple rows.
9. The lighting apparatus in accordance with claim 8 , wherein each of the rowed upstream optical elements has a front end reflector segment.
