Abstract

A lighting device includes a light source, a base and an articulated support. The support has a first arm which is rotatable relative to the base about a first axis, a second arm upon which the light source is mounted, and a joint section which connects the second arm to the first arm for movement relative thereto about a second axis which is parallel to the first axis. The second arm is also moveable relative to the joint section about a third axis which intersects, and is orthogonal to, the second axis to change the orientation of the light source relative to the base.

First claim

1 . A lighting device comprising:
a light source; a base; and a support; wherein the support comprises a first arm which is rotatable relative to the base about a first axis, a second arm upon which the light source is mounted, the second arm being substantially parallel to the first arm, and a joint section which connects the second arm to the first arm for movement relative thereto about a second axis which is parallel to the first axis; and wherein the second arm is moveable relative to the joint section about a third axis which intersects, and is orthogonal to, the second axis.

2 . The device of claim 1 , wherein the joint section moves with the second arm about the second axis.

3 . The device of claim 1 , comprising a spigot which extends along the second axis, and wherein the joint section comprises a recess for receiving the aperture.

4 . The device of claim 1 , comprising at least one retainer for retaining the second arm in one or more orientations relative to the joint section.

5 . The device of claim 1 , wherein the joint section comprises a shaft upon which the second arm is mounted, and about which the second arm rotates relative to the joint section.

6 . The device of claim 5 , wherein the shaft comprises one or more shaft recesses angularly spaced about the shaft, and wherein the second arm comprising a detent which is received by one of the recesses depending on the orientation of the second arm.

7 . The device of claim 6 , wherein the shaft comprises two shaft recesses which are spaced apart by 180°, and which are arranged such that, when the detent is received by a shaft recess, an optical axis of the light source is parallel to the first axis.

8 . The device of claim 1 , wherein the support is mounted on a body which is rotatable relative to the base about the first axis.

9 . The device of claim 8 , wherein the body is rotatable relative to the base about its longitudinal axis.

10 . The device of claim 8 , wherein the support extends substantially orthogonal to the longitudinal axis of the body.
