Abstract
A lamp stabilizer adapted to be mounted to the housing of a light fixture includes a mounting bracket secured to the light fixture and an elongated rigid rod slidably mounted for axial movement with respect to the bracket. The lamp stabilizer has a lamp engaging socket mounted on one end of the rod for selective engagement with an outer end portion of a lamp mounted in the housing. The lamp engaging socket is generally frustum-shaped and has at least one layer of heat insulating and lamp cushioning material secured to an inner side thereof for direct engagement with the outer end portion of the lamp. The lamp engaging socket is positioned with respect to the lamp by moving the rod with respect to the mounting bracket. A friction clip is selectively securable along the axial length of the rod and when secured thereto, engages the mounting bracket to restrict movement of the rod in direction away from the lamp. Preferably, the insulating and cushioning material has properties substantially equivalent to material sold under the trademark Fiberfrax.
