Combination lamp holder

Abstract

The present invention relates to a lamp holder that can align a lamp with respect to a lamp holder and further secures the lamp against loosening caused by environmental vibrations (i.e., vibrations that are germane or inherent to the specific lighting application in which the lamp holder is installed). In one embodiment, a conductive sleeve is provided that includes a threaded portion for receiving an associated lamp; a positioning element located near the top portion of the conductive sleeve for engaging an alignment prong (or projection) of the associated lamp; and at least one vibration dampener formed in a portion of the conductive sleeve, wherein the vibration dampener and the positioning element ensure that the lamp will not vibrate excessively and/or become misaligned with respect to the holder.
