Abstract

A camera comprising: a sensor holder, an image sensor mounted on the sensor holder, a mount holder, and a lens mount being adapted to receive a lens array and being mounted to the mount holder, wherein the sensor holder is attached to the mount holder, wherein a gap having an extension along an optical axis of the camera is formed between the sensor holder and the lens mount, and wherein the sensor holder is provided with a thermally conducting protrusion bridging the gap and being in contact with the lens mount at an interface allowing relative motion between the lens mount and the thermally conducting protrusion along the optical axis while maintaining contact between the lens mount and the thermally conducting protrusion.

First claim

What is claimed is:

1. A camera comprising:
a sensor holder;
an image sensor mounted on the sensor holder;
a mount holder; and
a lens mount being adapted to receive a lens array and being mounted to the mount holder,
wherein the sensor holder is attached to the mount holder,
wherein a gap having an extension along an optical axis of the camera is defined between the sensor holder and the lens mount, and
wherein the sensor holder is provided with a thermally conducting protrusion bridging the gap and contacting the lens mount at an interface allowing relative motion along the optical axis between the lens mount and the thermally conducting protrusion while maintaining contact between the lens mount and the thermally conducting protrusion.

2. The camera according to claim 1 , wherein the sensor holder is adhesively attached to the mount holder.

3. The camera according to claim 1 , wherein the interface comprises a first surface on the lens mount facing a second surface on the thermally conducting protrusion, wherein the first and second surfaces both have a normal extending perpendicular to the optical axis.

4. The camera according to claim 3 , wherein the first surface of the interface forms a circular outer envelope surface and the second surface of the interface forms a circular inner envelope surface.

5. The camera according to claim 1 , wherein the thermally conducting protrusion is positioned at an intermediate area of the sensor holder, the intermediate area extending around the image sensor and being inside a perimeter of the sensor holder.

6. The camera according to claim 5 , wherein the intermediate area is inside a perimeter defined by attachment points between the sensor support and the mount holder.

7. The camera according to claim 5 , wherein the thermally conducting protrusion covers at least 50% of the circumference of the intermediate area around the image sensor.

8. The camera according to claim 1 , wherein the sensor holder is a printed circuit board.

9. The camera according to claim 1 , wherein the thermally conducting protrusion is formed of thermally conducting material attached to the sensor holder.

10. The camera according to claim 1 , wherein the lens mount is formed of a thermally conducting material, preferably a metallic material.

11. The camera according to claim 1 , further comprising a lens array comprising a tubular member supporting one or more lenses, the tubular member being inserted into the lens mount.

12. The camera according to claim 11 , wherein the tubular member of the lens array is formed of a thermally conducting material, preferably a metallic material.

13. The camera according to claim 1 , wherein the lens mount comprises a tubular portion adapted to receive the lens array.

14. The camera according to claim 1 , wherein the mount holder comprises a tubular portion adapted to receive the lens mount.

15. The camera according to claim 1 , wherein the mount holder is formed of a polymer based material.

16. The camera according to claim 1 , wherein the interface is partially defined on a radially outer surface of the lens mount and partially defined on a radially inner surface of the thermally conducting protrusion.
