Abstract

In this paper, we analyzed carbonization pattern of Ligth Emitting Diode(LED) lamp that become burnout by outside flame. Surface side can know that void is formed greatly than central part in section analysis of electric wire that is carbonized by outside flame. Chared globe displayed special quality that lump of abnormal carbonization falls was formed, and becomes melting among carbonization process. The LED resistance of forward direction is about 1.74 [$M{\Omega}$], and backward resistance is about 140 [$M{\Omega}$]. We can know progress direction of flame through measurement of the LED resistance.
