Fluorescent bulb with impact-absorbing sleeve

摘要

An improved fluorescent bulb for use in a work lamp for rough service applications. The fluorescent bulb is of the type having a fluorescent tube which emits light when energized by electric power. A base portion connects to the fluorescent tube and encloses a base cavity which supports a starter switch bulb electrically connected to the fluorescent tube. The starter switch bulb is protectively surrounded by a preferably woven glass-fabric sleeve which absorbs impacts caused by relative movement of components within the base cavity, including the starter switch bulb itself.
