摘要:
A holder (50) for an arc tube-shroud assembly (52) (see FIGS. 3-5) comprises: a planar disc (54) having a plurality of shroud-holding arms (56) peripherally spaced about the disc and extending in a first direction (58). At least two arc tube holding arms 60 extend in an opposite direction (62) for positioning an arc tube (52a) laterally within a shroud (52b); and at least one arc tube locking tab (64) extends in the opposite direction (60) for positioning the arc tube (52a) axially within the shroud (52b). The planar disc (54) is provided with a plurality of venting apertures (82) sized to allow egress of pressurized gases but inhibit passage of axially-propelled arc tube shards in the event of a non-passive failure of an arc tube.
摘要:
A stem and lamp capsule are connected together as an assembly using a retainer such that the stem is clamped to one end of the retainer and the capsule is clamped to the other end of the retainer. An oxidizable fuse is connected between leads of the capsule and electrical conductors of the stem. The retainer maintains the rigidity of the assembly and keeps a constant distance between the stem and the lamp capsule so that the repeatability and failure parameters of the fuse length can be maintained within acceptable tolerance.
