Abstract

A lamp (10) constructed as a hand lamp and for static use. The lamp includes a lamp housing (12), a light source in the lamp housing, a lamp mounting (14) for mounting the lamp in a desired position on a surface and a universal joint (24, 26) coupling the lamp housing and the mounting together, whereby the lamp housing is universally adjustable in attitude relative to the mounting.

Claims

1. A lamp constructed as a hand lamp and for static use, the lamp comprising:

a lamp housing,

a light source in the lamp housing,

a lamp mounting for mounting the lamp in a desired position on a surface and

a universal joint coupling the lamp housing and the mounting together,

whereby the lamp housing is universally adjustable in attitude relative to the mounting, further comprising means for coupling the universal coupling to the lamp housing and lamp mounting such that the lamp housing and lamp mounting can be spaced apart and brought together, and in that the lamp housing and lamp mounting are universally adjustable in relative attitude when the lamp housing and lamp mounting are spaced apart.

2. The lamp according to claim 1, wherein the relative adjustability of the lamp housing and lamp mounting is restricted or prevented when the lamp housing and lamp mounting are brought together.

3. The lamp according to claim 1, wherein the lamp is constructed to be portable.

4. The lamp according to claim 1, wherein the lamp is an inspection lamp.

5. The lamp according to claim 1, comprising at least one LED light source in the lamp housing.

6. The lamp according to claim 1, wherein the lamp housing is adapted to contain a battery powering the light source.

7. The lamp according to claim 1, wherein the lamp mounting comprises a permanent magnet.

8. The lamp according to claim 1, wherein the universal joint comprises a ball and socket joint.

9. The lamp according to claim 8, comprising means for restraining relative movement of the ball and socket joint.

10. The lamp according to claim 9, wherein the restraining means comprise an array of projections on one of the parts comprising the ball and socket joint and a corresponding array of depressions on the other of members comprising the ball and socket joint and in which the projections are arranged to fit.

11. The lamp according to claim 8, wherein the ball part of the ball and socket joint is coupled to a shaft, which shaft is mounted in the lamp housing, the arrangement being such that the ball part can be moved axially from a first position in which the lamp housing and the mounting lie closely adjacent to one-another to a second position in which the lamp housing and mounting are spaced apart, the second position permitting articulation of the ball and socket joint.

12. The lamp according to claim 11, comprising a detent coupled between the lamp housing and the shaft to tend to retain the shaft in the first and second positions.

13. The lamp according to claim 1, wherein the ball and socket joint is axially movably mounted in the lamp mounting.

14. The lamp according to claim 13, comprising means for restraining axial movement of the ball and socket joint in the lamp mounting.

17. The lamp according to claim 7, wherein the ball and socket joint is axially movably mounted in the lamp mounting.
