  • General service tungsten-halogen incandescent lamp having improved filament shock resistance
    Patent number: 4743803
    Abstract: A mounting arrangement for disposing a light source comprising an inner envelope within an outer envelope with both envelopes comprising a general service tungsten-halogen incandescent lamp is disclosed. The mounting arrangement has parameters which are selected in accordance with the ratio between the natural frequency characteristics of the filament of the light source and the mounting arrangement itself. The selected ratios of the natural frequencies of the filament and the mounting arrangement reduce the typically experienced shock vibrations of the general service lamp that are transmitted to the filament and thereby improves the overall life expectancy of the general service incandescent lamp.
