摘要：An arc discharge lamp having an end-of-life structure and including a light-transmissive envelope having a tubular-shaped main body and a press seal disposed ateach end of the main body. An electrode filament having a pair of ends is located in eachend of the envelope. Each electrode filament end is in a contiguous relationship with aninside surface of the lamp envelope. When one of the electrode filaments is depleted ofelectron-emissive material, increased heating of the electrode filament caused by anincrease in cathode fall voltage, produces a localized hot spot on the internal surface ofthe envelope. This localized heating causes a puncture in the lamp envelope andevacuation of the lamp. The introduction of external atmosphere into the lampextinguishes the arc discharge and renders the lamp inoperable.
