ABSTRACT:
A lamp assembly having an improved mounting arrangement for a light source and shroud configuration provides for such improved mounting arrangement in a manner such that manufacturing of the lamp assembly is simplified and the light source is protected against vibration and shock forces during manufacture and operation. The light source includes an arc tube which is under pressure and which is disposed within a shroud member that is then mounted within an outer lamp envelope. Top and bottom support members made of an insulative material are disposed on opposite ends of the shroud member. One of the lead wires used to couple energy to the light source, extends through the shroud member and has an insulative sleeve disposed in surrounding relation to a portion thereof. As the one lead wire extends through a hole formed in the bottom support member, a resilient clip member is slid over the bottom portion of such lead wire. The resilient clip member contacts the bottom of such bottom support member and by virtue of a tapered neck portion, prevents movement of the support member and the shroud back down on the lead wire. The resilient clip member has a flat upper portion which is flexible so that vibration and shock forces that would otherwise be transmitted to the light source are transmitted instead through the lead wire that extends through the shroud member.
