COMPACT SINGLE-ENDED INCANDESCENT LAMP HAVING IMPROVED FILAMENT MOUNT ASSEMBLY

The coiled-coil filament of a single-ended halogen type lamp is suspended in generally coaxial position within a tubular envelope by a pair of rigid lead wires of unequal length that have smooth substantially straight ends which are slip-fitted into and hot clamped to singly-coiled legs provided at each end of the coiled-coil. An end segment of the longer lead wire is bent into a transversely-extending loop which is disposed in loose nesting relationship with the top of the bulb and thus also serves as an integral mount-positioning-and-bracing means. An optional bridge and anchored auxiliary support wire for the filament provide additional shock-proof protection. The simplicity of the resulting mount structure reduces the manufacturing cost of the lamp without affecting lamp quality or performance.
