Abstract

A dampener configured to augment the mounting of a lamp in a socket by resisting displacement of the lamp relative to the socket. The dampener is made from a material able to absorb vibrations and to reduce or prevent vibrations in the lamp. The dampener is made in one piece or more pieces, wherein each piece is interposable in whole or in part between the socket and the lamp base to insulate the lamp in whole or part against the vibration translated through the socket or surrounding air.

Claims

1. A dampener configured to augment the mounting of a lamp in a socket by resisting displacement of the lamp relative to the socket, wherein the dampener is made from a material able to absorb vibrations and to reduce or prevent vibrations in the lamp, wherein the dampener is in one or more pieces, wherein each piece is configured to be interposable in whole or in part between the socket and the lamp base to insulate the lamp in whole or part against the vibrations translated through the socket or surrounding air.

2. The dampener according to claim 1, wherein said material of the dampener comprises a high temperature silicone or rubber material.

3. The dampener according to claim 1, wherein the dampener comprises an annular ring made from non-deformable resilient material comprising a generally cylindrical body.

4. The dampener according to claim 3, wherein the cylindrical body has a cylinder wall thickness that tapers towards one end of the cylindrical body, wherein the annular ring is mounted onto a lamp'"'"'s shaft, such that the tapered, cylindrical wall is oriented towards the free end of the shaft.

5. The dampener according to claim 3, wherein the cylindrical body has a cylinder wall thickness (t) that is constant.

6. A lighting assembly comprising:

a lamp holder housing a metal socket;

a lamp mountable in the socket; and

a dampener according to claim 1.

7. A method of assembling a lighting assembly comprising:

mounting a dampener according to claim 1 onto a shaft of a lamp;

inserting the shaft into a metal socket so that the dampener is compressed between an internal wall of the metal socket and an external wall of the shaft.

8. The method according to claim 7, wherein the dampener comprises an annular ring made from one or more non-deformable resilient material(s) comprising a generally cylindrical body.

9. The method according to claim 8, wherein the cylindrical body has a cylinder wall thickness that tapers towards one end of the cylindrical body, and the mounting step is performed so that the tapered end is oriented towards a free end of the shaft.
