B2
Abstract:
To provide a halogen lamp that has a light emitting portion made of a coiled filament inside an arc tube, and in which the light emitting portion is divided into at least two, and the divided light emitting portions are electrically connected via a short-circuit conductor rod, the heat loss generated in the short-circuit conductor rod is further reduced to accelerate the rise of the light emitting portion and increase the heat energy in the light emitting portion.SOLUTION: A short-circuit conductor rod forms a non-light emitting portion, and has a recrystallized portion in which a crystal structure is recrystallized at least in a part in the longitudinal direction thereof.SELECTED DRAWING: Figure 1
