新的硅衬底工艺可以将LED生产成本降低75%以上。人们购买高能效LED(发光二极管)灯泡的障碍莫过于成本。尽管高能效LED灯泡的寿命,比1美元的普通白炽灯或4美元的节能荧光灯长得多。但它们标签上的价格也令人退缩:一个相当于60瓦效果的LED灯泡在15美元至25美元之间。现在,世界上最大的LED制造商之一欧司朗光电半导体公司(Osram Opto Semiconductors)表示,它已经拥有一种完善的技术,能够显著降低LED的生产成本。
The new silicon substrate process can reduce LED production costs by more than 75%. There are more hurdles to buying energy-efficient LED (light-emitting diode) bulbs. Despite the fact that energy-efficient LED bulbs last longer than regular 1-dollar incandescent or 4-dollar CFLs. But the price on their label is also a sign of retreat: an equivalent of 60 watts of LED bulbs in the 15 to 25 US dollars between. Now, Osram Opto Semiconductors, one of the world’s largest LED manufacturers, said it already has a sophisticated technology that can significantly reduce LED manufacturing costs.
