Abstract
In this paper, we conducted experiments on damaged patterns of incandescent lamps by external stress, such as external flame or external impact. Glass bulbs were melted and filaments were evaporated by external flame when the bulbs were lit, and finally molten marks were recognized at the filaments. Also, there were some differences in absorption patterns of evaporated filament elements according to set-up directions, and evaporated filament elements were absorbed in lead-in wires, support, inside of glass. In case the bulbs were lit and they were damaged by external impacts, filament burned out. Filaments were not evaporated but melted. We expect that this results could be used to judge whether electric current flew through incandescent lamps or not in fire site.
