Abstract

An apparatus for mounting a plurality of light sources of a Lidar is provided. The apparatus comprises: a plurality of mounting units held by a base structure and a fixation component that is disposed away from the base structure along a longitudinal direction of a mounting unit, the base structure and the fixation component configured to allow an adjustment of the plurality of mounting units along a horizontal direction. The plurality of the mounting units includes structures that accept the plurality of the light sources and control directions of light beams emitted by the plurality of light sources along a vertical direction.

Claims (21)

1. An apparatus for mounting a plurality of light sources of a Lidar comprising:

a plurality of mounting units held by a base structure and a fixation component that is disposed away from the base structure along a longitudinal direction of a mounting unit, the base structure and the fixation component configured to allow an adjustment of the plurality of mounting units along a horizontal direction,

wherein the plurality of the mounting units includes structures that accept the plurality of the light sources and control directions of light beams emitted by the plurality of light sources along a vertical direction.

2. The apparatus of claim 1 , wherein the base structure comprises a feature to receive the plurality of mounting units.

3. The apparatus of claim 2 , wherein the feature accommodates a shape or size of the plurality of mounting units.

4. The apparatus of claim 2 , wherein the feature allows the adjustment of the plurality of mounting units along the horizontal direction.

5. The apparatus of claim 1 , wherein the fixation component comprises a docking structure to receive the plurality of mounting units.

6. The apparatus of claim 5 , wherein the docking structure accommodates a shape or size of the plurality of mounting units.

7. The apparatus of claim 5 , wherein the docking structure allows the adjustment of the plurality of mounting units along the horizontal direction.

8. The apparatus of claim 1 , wherein the plurality of light sources are individually controlled to generate the light beams.

9. The apparatus of claim 1 , wherein a distribution pattern of the light beams is independent of an arrangement of the plurality of light sources.

10. The apparatus of claim 9 , wherein the arrangement of the plurality of light sources is designed to facilitate heat dissipation.

11. The apparatus of claim 9 , wherein the arrangement of the plurality of light sources is decoupled from a vertical angular resolution defined by the light beams.

12. The apparatus of claim 1 , wherein the plurality of the light sources are coupled to a first end of a plurality of optical fiber elements.

13. The apparatus of claim 12 , wherein the plurality of light sources is optically coupled to the plurality of optical fiber elements using an optical coupling element.

14. The apparatus of claim 1 , wherein the structures for accepting the plurality of the light sources are integrally formed with the plurality of mounting units.

15. The apparatus of claim 1 , wherein the structures for accepting the plurality of the light sources comprise a set of slots or channels.

16. The apparatus of claim 15 , wherein the set of slots or channels are non-uniformly distributed along a length direction of at least one mounting unit.

17. The apparatus of claim 15 , wherein the set of slots or channels are located on two opposing sides of at least one mounting unit.

18. The apparatus of claim 15 , wherein each of the set of slots or channels has a pre-determined tilt angle with respect to the horizontal direction.

19. The apparatus of claim 18 , wherein the direction of the light beams along the vertical direction is controlled by selecting a given slot or a given channel with a pre-determined tilt angle from the set of slots or channels.
