<p>A double-enveloped tungsten halogen incandescent lamp having a light-source capsule containment device wherein a knitted wire mesh surrounds the light-source capsule and may be anchored to the capsule, stem, or lead-in wires. In the event of a burst of the light-source capsule, the containment mesh substantially restricts shards of the capsule from shattering the outer envelope of the lamp. In some embodiments, a crumpled portion of the containment mesh is positioned above the capsule and provides a collision-absorbing cushion in the event the capsule and mesh are propelled against the outer envelope by the burst of the light-source capsule whereby further protection against the shattering of the outer envelope is provided. Lamps with such containment devices have improved operational safety characteristics.</p> |
