Project Name: Afterglow Life Controllable Rare Earth AC LED Huminescent Materials and Devices

Project Owner: Changchun Institute of Applied Chemistry (CIAC) Chinese Academy of Sciences

Project Profile: The rare earth LED phosphors the decay time of which can be easily tuned and matches well with the frequency of AC current were first time synthesized. The technology succeeds in solving the stroboscopic problem of AC LED. Furthermore, it enables the emergence of the novel generation technology of the white AC-LED lighting with the absolutely independent intellectual property rights of China which overweighs the previous one in many aspects, such as the excellent heat dissipation, higher energy conversion efficiency, the smaller volume, twice as long as in the life time, and the decrease of the energy consumption and the cost by up to 15% and 20%. The products have been sold to several countries like the United States, Canada, Mexico, Spain, Brazil, and so on, which has brought the sum of over 300 million in the revenue for the cooperation company. The technology so far has been bestowed by the Institution of Engineering and Technology (the second biggest international society of the professional engineering) for the nomination award of Energy Innovation and Architectural Environment in 2012 and the World Gold Kangaroo Innovation Award in 2013 by Australa. This work was selected Top Ten Chinese Rare Earth Technology News of 2013.
