| Abstract |
In this paper. we experimented and analyzed about evaporation and breaking process of filament by external flames and adsorption pattern in lamp bulb of evaporated filament particle according to the set-up directions of incandescent lamps. In the results of experiments, we could know that filament evaporation behavior of incandescent lamp that is established by down direction happened most vigorously and is difference in adsorption pattern of filament particle that is vaporized according to set-up directions. Also, glass bulbs were melted and filaments were evaporated by external flames, and finally molten marks were discriminated. We expect that become important data that this study finding reveals burnout cause of incandescent lamp in scene of a fire. |
