Abstract

A lighting device includes a support and an arm which is mountable on the support in a selected orientation for movement relative thereto. The arm has a channel extending at least partially along the length of the arm. A light source is mounted on the arm. A first electrical connector is mounted on the support, and a second electrical connector is mounted on the arm. The second electrical connector is detachably electrically connected to the first electrical connector, and is moveable along the channel with lengthwise movement of the arm relative to the support.

First claim

The invention claimed is:

1. A lighting device comprising:
a support;
a first electrical connector mounted on the support;
an arm comprising a first end, a second end spaced from the first end along the length of the arm, and a channel extending at least partially along the length of the arm;
a light source mounted on the arm, the arm being removably mountable on the support in a first orientation, in which the light source is located to one side of the first electrical connector, and a second orientation in which the light source is located to the other side of the first electrical connector, wherein the arm is removable from the support for switching between the first and second orientations; and
a second electrical connector which is mounted to the arm and connected to the light source and detachably electrically connected to the first electrical connector, the second electrical connector being moveable along the channel with lengthwise movement of the arm relative to the support, wherein the second electrical connector is detachable from the first electrical connector to enable the arm to be removed from the support for switching between the first and second orientations.

2. The lighting device of claim 1 , wherein the channel is located on one of an upper surface and a lower surface of the arm.

3. The lighting device of claim 1 , wherein the first electrical connector is moveable relative to the support to connect the second electrical connector to the first electrical connector.

4. The lighting device of claim 3 , wherein the first electrical connector is pivotable relative to the support to connect the second electrical connector to the first electrical connector.

5. The lighting device of claim 3 , wherein the first electrical connector is moveable relative to the support between a raised position and a lowered position.

6. The lighting device of claim 1 , wherein the first electrical connector is magnetically attracted towards the second electrical connector.

7. The lighting device of claim 1 , wherein the support comprises a plurality of guides for releasably retaining the arm and for guiding movement of the arm relative to the support.

8. The lighting device of claim 7 , wherein the plurality of guides comprises a set of guides between which the arm is insertable.

9. The lighting device of claim 8 , wherein at least one of the set of guides is arranged to be at least partially received within said channel.

10. The lighting device of claim 8 , wherein one of the set of guides is moveable relative to the arm between a deployed position for engaging the arm and a retracted position for allowing the arm to be detached from the support.

11. The lighting device of claim 10 , wherein the moveable guide is biased towards its deployed position.

12. The lighting device of claim 10 , wherein the moveable guide is at least partially located in a second channel of the arm when in its deployed position.

13. The lighting device of claim 12 , wherein the second channel is located on an opposite side of the arm to said channel.

14. The lighting device of claim 7 , wherein each of the guides comprises a roller which is rotatably mounted on a support plate.
