Abstract

An electric lamp having an envelope, a light-source capsule mounted within the envelope and a containment coating. The containment coating, which is disposed sub­ stantially over the outer envelope, has the capability of pre­ serving the integrity of the envelope from piercing, due to shard dispersion from the light-source capsule, in the un­ likely 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 coat­ ing is resistant to, and exhibits a high degree of tensile strength at, high temperatures and is substantially unaffect­ ed by ultraviolet radiation.
