    • The present invention provides a tungsten-halogen light bulb having an arc tube (1) with a seal portion (5) at one end. A filament (8) is provided in the interior of the arc tube, and a basic gas mainly comprising at least either gaseous xenon or gaseous krypton is filled in the arc tube. When V (V) denotes a rated voltage of the tungsten-halogen light bulb, P(MPa) denotes a filling pressure of the basic gas at a room temperature, and Xe vol.% and Kr vol.% respectively denote composition ratios of the gaseous xenon and of the gaseous krypton, the following formulas (1) and (2) are satisfied simultaneously, in which '%' means 'volume %'. V≥100 (Volt) P≥0.7+{0.1 × (Kr%/(Kr%+Xe%))} In these formulas, Kr%+Xe%=100(%), 0≤Kr%≤100, and 0≤Xe%≤100. Accordingly, a crack at the seal portion (5) of the arc tube (1) is prevented and the lifetime is improved.
    • 本发明提供一种具有在一端具有密封部分(5)的电弧管(1)的卤钨灯泡。 灯丝(8)设置在电弧管的内部,并且主要包含气态氙气或气态氪气的碱性气体填充在电弧管中。 当V(V)表示钨卤素灯泡的额定电压时,P(MPa)表示室温下碱性气体的填充压力,Xe体积%和Kr体积%分别表示 气态氙气和气态氪同时满足下列公式(1)和(2),其中“%”表示“体积%”。 V≥100(Volt) P≥0.7+ä0.1x(Kr%/(Kr%+ Xe%)) ü在这些式中,Kr%+ Xe%= 100(%),0≤Kr%≤100,0≤Xe%≤100。 因此,防止了电弧管(1)的密封部(5)处的裂纹,寿命提高。
