Abstract

The invention relates to a reading lamp for installation in a cabin trim element ( 4 ) of a vehicle, in particular of an aircraft, comprising
an installation frame ( 1 ) having a ring element ( 2 ),
a lamp housing ( 7 ) having a mating support surface ( 8 ), and
a clamping ring ( 9 )
wherein the clamping ring ( 9 ) is connected to the installation frame ( 1 ) by means of tension spring elements ( 10 ), such that the lamp housing ( 7 ) is forced against the support surface ( 6 ) of the inner surface of the ring element ( 2 ) by means of the clamping ring ( 9 ) and may be moved with respect to the installation frame ( 1 ) in the manner of a ball and socket joint.

First claim

The invention claimed is:

1. A reading lamp for installation in a cabin trim element of a vehicle, comprising:
an installation frame having a ring element,
wherein a flange extends on a visible side of the installation frame to bear against an edge section surrounding a hole in the cabin trim element,
wherein securing elements are provided on the ring element to secure the installation frame on the cabin trim element, and
wherein an inner surface of the ring element has a support surface against which a lamp housing bears in a form-fitting manner, the lamp housing being configured at least partially in the shape of a ball;

the lamp housing comprising a mating support surface and a first sliding surface, wherein the mating support surface is configured to bear against the support surface and be moveable with respect to the support surface; and
a clamping ring comprising a second sliding surface, wherein the second, sliding surface is configured to bear against the first sliding surface and be moveable with respect to the first sliding surface,
wherein the clamping ring is connected to the installation frame through tension spring elements, such that the lamp housing is forced against the support surface through the clamping ring and is movable with respect to the installation frame in the manner of a ball and socket joint.

2. The reading lamp according to claim 1 , wherein the vehicle is an aircraft.

3. The reading lamp according to claim 1 , wherein the clamping ring is made of PTFE.

4. The reading lamp according to claim 1 , wherein the tension spring elements comprise retaining clips made from a spring steel.

5. The reading lamp according to claim 1 , wherein the securing elements comprise first latching springs, wherein a first end of the first latching springs has a first separation with respect to the flange.

6. The reading lamp according to claim 5 , wherein the securing elements comprise second latching springs, wherein a second end of the second latching springs has a second separation with respect to the flange, and wherein the second separation is smaller than the first separation.

7. The reading lamp according to claim 6 , wherein the first and the second latching springs are respectively attached adjacent to one another on the installation frame.

8. The reading lamp according to claim 1 , wherein the lamp housing is formed of a first housing shell, which comprises the first sliding surface, and a second housing shell, which comprises the mating support surface.

9. The reading lamp according to claim 8 , wherein the first and the second housing shell are latched to one another.
