Halogen incandescent lamp and a lighting apparatus using the lamp
摘要:
A halogen incandescent lamp comprises a light-transmitting envelope filled with a gas including a halogen gas and an inert gas. A pair of inner conductive wires is arranged in the envelope. A triple-coiled filament, which has a first coiling, a second coiling, and a third coiling having about 1.5 to about 4 turns, is re-crystallized, is arranged in the envelope, and is connected between ends of the inner conductive wires. The triple-coiled filament is held by a support member. The halogen incandescent lamp may be utilized to a lighting apparatus.
