Goodbye, fluorescent light bulbs!——再见,荧光灯泡! - 午夜天使 - 品茗,Mm设计间的快乐
 
       日前,美国北卡罗来纳州维克森林大学(美国的一所私立大学)的科学家们发明了一种无闪烁、不易碎,可作为大型照明应用的替代荧光灯及LED的新光源。新技术又称诱导聚合物致电发光(FIPEL)技术,运用了可发光的纳米材料为原料。该光源根据场诱导聚合物电致发光技术(FIPEL)发出柔和的白光,不仅不 会产生热,而且还可以更好地提供照明,这种光源将会为每一座办公建筑节约很多成本,并降低环境影响。据报道,新灯管不仅能够无噪声地发出轻柔的白光,并且 还具有防震、寿命周期长(10年),在低温下运行,可弯曲成任何形状以及能效高等优点。据介绍,这种新的照明解决方案至少是紧凑型荧光灯(CFL)灯泡两倍的效率,与LED看齐。

    20世纪60年代开发的发光二极管(或称LED技术),其发光光谱几乎全部集中于可见光频段,发光效率极高,是目前最高效的发光技术之一,但LED也存在 一些缺陷,如灯管很容易过热,发出的偏蓝光让人常感不适;而另一种高效发光灯管—紧凑型荧光灯则由于含有少量汞,一旦破碎或处理不当,会造成环境污染。

    未来,这种可塑性强、持久耐用的塑料发光层有可能能够克服目前所有高效发光技术的局限性。但新技术的市场化过程还需要一段时间。为此,维克森林大学专门创 办了一个发光技术商业化的公司Purelux。该公司对这种可弯曲灯管抱有极高的希望:新技术未来的实际应用潜力将不可思议。目前已经有企业表示愿意生产 诱导聚合物致电发光灯管,并有望在2013年首次实现量产化。据称该光源可制成任何颜色、任何形状,可替换范围广,从8英尺的正方形办公室照明光源到适应 的家用灯具。

    根据美国能源信息局的数据,2010年全美住宅和商用照明总计用电量为4990亿度,约为美国总耗电量的13%。科学家预言新光源技术的诞生和应用有望进一步降低美国照明用电量。



维克森林大学
Wake Forest University)官网介绍:

The lighting, based on field-induced polymer electroluminescent (FIPEL) technology, also gives off soft, white light – not the yellowish glint from fluorescents or bluish tinge from LEDs.

“People often complain that fluorescent lights bother their eyes, and the hum from the fluorescent tubes irritates anyone sitting at a desk underneath them,” said David Carroll, the scientist leading the development of this technology at Wake Forest. “The new lights we have created can cure both of those problems and more.”

“这种塑料灯泡的学名叫做聚合物致电发光灯(Fipel),”来自北卡罗来纳州威克森林大学的博士大卫·卡罗尔说,“Fipel 由三层白色的纳米聚合物制成,它可以被做成各种形状。荧光灯会产生刺眼的蓝色光,使人眼疲劳;Fipel 发出的光则非常自然,如果客户需要,它还能发出五颜六色的光。”

The team uses a nano-engineered polymer matrix to convert the charge into light. This allows the researchers to create an entirely new light bulb – overcoming one of the major barriers in using plastic lights in commercial buildings and homes. The research supporting the technology is described in a study appearing online in advance of publication in the peer-reviewed journal Organic Electronics.

The device is made of three layers of moldable white-emitting polymer blended with a small amount of nanomaterials that glow when stimulated to create bright and perfectly white light similar to the sunlight human eyes prefer. However, it can be made in any color and any shape – from 2×4-foot sheets to replace office lighting to a bulb with Edison sockets to fit household lamps and light fixtures.

This new lighting solution is at least twice as efficient as compact fluorescent (CFL) bulbs and on par with LEDs, but these bulbs won’t shatter and contaminate a home like CFLs or emit a bluish light like LED counterparts.

“If you wanted blue lights, discos would still be popular. You want lights that have a spectral content that is appealing to us inside of a building,” Carroll said. “You want a light that won’t shatter and create a hazmat situation while your children are around.”

Carroll’s group is the first to make a large-scale FIPEL that can replace current office lighting and is based on natural white light. Beyond office and home lighting, Carroll sees potential uses for large display lighting, from store marquees to signs on busses and subway cars.

FIPELs also are long-lasting; Carroll has one that has worked for about a decade.

Wake Forest is working with a company to manufacture the technology and plans to have it ready for consumers as early as next year.

Carroll is the Director of the Center for Nanotechnology and Molecular Materials at Wake Forest University. Center scientists have developed innovative technology including highly efficient plastic solar cells; Power Felt, a fabric that can use body heat to charge small electronics; and a combination solar-thermal heat pump.
