日本生产汽车照明器具的森山产业公司日前宣布，研制出使用寿命为２万ｈ的高亮度灯泡，其寿命相当于普通灯泡的２０倍。该公司采用独自开发的技术将不易传导热能的氙气密封入灯泡内，以减少热能的损耗。这样，既增加了发光强度，又提高了发光部件（钨丝等）的耐久性。与目前灯 Moriyama Industries, which produces automotive lighting in Japan, announced that it has developed a high-brightness bulb with a service life of 20000 h, which has a life expectancy of 20 times that of an ordinary bulb. The company uses a self-developed technology to seal xenon, which is less heat conductive, into the bulb to reduce heat loss. In this way, the luminous intensity is increased, and the durability of the light-emitting components (such as tungsten wire) is also improved. With the current lamp
