电灯光亮来自白炽灯丝。
The light of an electric lamp comes from an incandescent filament.
事实上，氩元素的浓度相当高，如果房间里有电灯泡被打破，灯丝却还可以继续发亮。
In fact, the argon would be so thick that if a light bulb inside the room were to break, the filament would keep glowing.
卤素灯的钨灯丝在使用过程中会慢慢的蒸发，直到最后断掉。由于没有卤素灯那样脆弱的钨灯丝，氙气气体放电灯十分耐用，其使用寿命至少不低于汽车的使用寿命。
Lacking the halogen's delicate tungsten filament, which slowly evaporates with use until it finally “blows”, xenon discharge lamps are robust enough to last at least the lifetime of the car.
