Claims13
A lamp, comprising:
- a lamp body which houses a light source;
- an electrical connector for connecting the lamp to a socket by a rotational coupling;
- and
- a clutch between the lamp body and the electrical connector for providing rotational coupling or else allowing rotational slippage between the lamp body and the electrical connector, in dependence on a torque applied between the lamp body and the electrical connector;
- the clutch comprises a first component which forms part of the electrical connector and a second component which forms part of the lamp body;
- wherein the first component comprises a first, outer, annular tooth ring and the second component comprises a second, inner, annular tooth ring, wherein the second annular tooth ring is compressible to release engagement between teeth of the first and second annular tooth rings.
