德国Fraunhofer大学研制出一种发白光的LED,据称,这是世界上发纯白光的首创产品。 此产品是利用发光变换技术来产生白光,即将GaN三色LED与波长可变且发明亮光的发光染料组合在一起。它的寿命可达到10万小时,能连续工作11年以上,比白炽灯泡长50倍。可广泛应用于飞机、火车、汽车作信号灯或仪表读出照明灯,能在白炽灯泡易碎或易引起火灾的环境下使用。该产品已申请两项专利。
Fraunhofer University in Germany developed a white LED, which is said to be the world’s first pure white hair products. This product is the use of luminescence conversion technology to produce white light, the GaN tri-color LED is a variable wavelength and the invention of light-emitting luminescent dye combination together. Its life expectancy can reach 100,000 hours, can work continuously for more than 11 years, 50 times longer than incandescent bulbs. Can be widely used in aircraft, trains, cars for traffic lights or instrument readout lights, incandescent bulbs in a fragile or easy to cause fire environment. The product has applied for two patents.
