<p>PROBLEM TO BE SOLVED: To solve problems caused by the peeling or falling of an igniting material by connecting an exothermic material of flammable metal to a firing material, and firing the firing material by the exothermic of the exothermic material without using the igniting material of a chemical material. SOLUTION: A tungsten fine wire is used as a heat generating material 4, connected to inner lead wires 3, 3, and current is carried to the heat generating material 4 to red heat it. As a firing material 5, a flammable fine wire of zirconium, aluminum, hafnium or the like is used, and fixed to the heat generating material 4. When current is carried to the heat generating material 4 through a base part 8, the lead wires 3, 3, the exothermic material 4 is red heated, the firing material 5 catches fire, a luminescent material 6 ignites, consumes oxygen to instantly burns, and emits light to the outside of a glass bulb 1. Since an igniting material is not used differently from the conventional flash lamp, problems caused by the peeling or falling of the igniting material is completely solved.</p> |
