Abstract

A light device, especially a signal lamp for motor vehicles, comprising a carrier bushing (1) with a translucent cover (2) and an inner chamber (3), wherein a lighting unit (4) is mounted providing the light signaling function, and one light source (91), and a filter (6) with at least one first input surface (83) for entry of at least part of light rays (100) generated by the light sources, and with at least one first output surface (82) designed to emit first light beam (102). The filter includes first segment (8) with the first output surface and second segment (7) with at least one second input surface (73) for entry of at least part of light rays generated by the light sources, and with at least one second output surface (72). The shape of the second output surfaces creates a designer element as a light emitting pattern emitted from those surfaces.

First claim

The invention claimed is:

1. A signal lamp for a motor vehicle, said signal lamp comprising a housing defining an inner chamber covered by a transparent cover to separate the inner chamber from an outside environment of the motor vehicle, the chamber of the signal lamp comprising:
(a) a first lighting unit associated with one or more first light sources, wherein the first lighting unit is configured to provide a light signaling function; and
(b) at least one second lighting unit separate from the first lighting unit comprising one or more second light sources and a filter, wherein the filter contains—
a first segment comprising at least one first input surface for the entry of at least a part of light rays generated by the one or more second light sources and at least one outwardly oriented first output surface having peripheral edges and configured to emit a first light beam, and
a second segment comprising at least one second input surface for the entry of at least a part of light rays generated by the one or more of the second light sources and one or more second output surfaces having peripheral edges and a perimeter,
wherein the first segment and the second segment are created with different materials,
wherein the second segment is inserted with the second output surface into the first segment in such a way that in a front view, the second output surface and the first output surface are arranged with a gap or without a gap next to each other and the second output surface is surrounded by the first output surface along at least a part of the perimeter of the second output surface,
wherein the second output surface of the second segment does not lie on the same plane as the first output surface of the first segment, and
wherein the at least one of first input surface of the first segment is arranged so that light rays enter the at least one of first input surface without having passed through the second segment.

2. The signal lamp according to claim 1 , wherein at least part of the peripheral edges of at least one the second output surfaces continues the peripheral edges of an adjacent first output surface so that at least part of the second output surfaces and the adjacent first output surface form a continuous output surface together.

3. The signal lamp according to claim 1 , wherein the filter is created as a compact casting.

4. The signal lamp according to claim 1 , wherein the first segment of the filter is designed as a diffusion means adapted with its internal and/or external structure to emit the first light beam.

5. The signal lamp according to claim 1 , wherein the second segment is configured to emit a second light beam from the second output surface in a predefined direction with predefined diffusion.

6. The signal lamp according to claim 1 , wherein the first segment of the filter is made of a transparent/clear material.

7. The signal lamp according to claim 1 , wherein a second light beam emitted from the second output surface has a higher intensity than a first light beam emitted from the first output surface.

8. The signal lamp according to claim 1 , wherein the first segment and the second segment of the filter are mutually arranged and adapted in such a way to prevent passing of the light rays from the second segment into the first segment and/or from the first segment to the second segment.

9. The signal lamp according to claim 1 , wherein in the propagation direction of the light rays generated by at least one of the second light sources, an optical element for routing the light rays to the required direction is arranged before the filter.

10. The signal lamp according to claim 9 , wherein the optical element is an optical structure and/or reflective surface and/or collimating member.

11. The signal lamp according to claim 1 , wherein the second segment is designed as a light guide.

12. The signal lamp according to claim 1 , wherein the signal lamp comprises at least two second light sources and the second segment is fitted with at least two second input surfaces for binding the light into the second segment from the said two second light sources.

13. The signal lamp according to claim 1 , wherein the signal lamp comprises at least two second light sources, the second segment being fitted with a stepwise shaped surface comprising, in a mutually alternating way, second input surfaces designed to bind the light generated by one second light source, and reflective surfaces designed to direct the light that has been bound to the second segment from another second light source.

14. The signal lamp according to claim 1 , wherein the second segment is fitted with a stepwise shaped surface comprising, in a mutually alternating way, second input surfaces for binding light from one second light source or one group of the second light sources on the one hand, and at least one second input surface for binding light from another second light source or from another group of second light sources.

15. The signal lamp according to claim 1 , wherein the second light sources are situated in the inner space on a same carrier.

16. The signal lamp according to claim 1 , wherein the second segment of the filter is configured to emit a second light beam of a different color than a first light beam emitted by the first segment of the filter.

17. The signal lamp according to claim 1 , wherein the second segment of the filter is adapted to bind light rays of different colors to emit second light beams of different colors, wherein the second light beams having different colors that are emitted from the same second output surface.

18. The signal lamp according to claim 1 , wherein the second output surface protrudes over the first output surface in the direction towards the transparent cover.
