National Yunlin University of Science and Technology (Yuntech) and Full-Sun Optotech Co. Ltd. have jointly developed the world’s first phosphorless light-emitting diode lights, Yuntech President Yang Yeong-bin announced Dec. 14.
As a result of the breakthrough technology, the new LED lights have a high color-rending index and a low luminous decay rate, two features that cannot be found in any other LED lights currently in use, Yang added.
He noted that after the lamps were left on continuously for 9,000 hours, they showed a luminous decay rate of only about 10 percent.
“This proves that even without phosphorus, our LED lights can last for at least 100,000 hours,” Yang stressed.
He further noted that power consumption of an 80-watt LED light is only 32 percent of a traditional 250 watt mercury road lamp and has a much better light uniformity. Yuntech has installed 17 such lights on its campus, according to Yang.
