<p>An electric lamp having an envelope, a light-source capsule mounted within the envelope and a containment coating. The containment coating, which is disposed substantially over the outer envelope, has the capability of preserving the integrity of the envelope from piercing, due to shard dispersion from the light-source capsule, in the unlikely event that the capsule should fracture. One example of the coating consists of a fluoropolymer material such as a perfluoroalkoxy resin (P.F.A. Teflon). The containment coating is resistant to, and exhibits a high degree of tensile strength at, high temperatures and is substantially unaffected by ultraviolet radiation.</p> |
