Crystal IS and Sanan Optoelectronics jointly develop of commercial UV-C LEDs

Date Announced: 06 May 2009 -- China’s largest LED manufacturer to accelerate commercialization of Crystal IS’s proprietary technology GREEN ISLAND, N.Y. -- Crystal IS, Inc., the world’s leading developer of ultraviolet light emitting diodes (UV-C LEDs) and Sanan Optoelectronics Co. Ltd., the largest manufacturer of full color LEDs in the People’s Republic of China, today announced they had signed a memorandum of understanding (MOU). The MOU defines a joint development program, whose goal is to establish pilot manufacturing of LEDs operating in the UV-C part of the electromagnetic spectrum. During the term of this MOU, both parties intend to negotiate a long-term business agreement covering high-volume manufacturing, marketing and sales. “Working with an experienced and dynamic company like Sanan Optoelectronics will significantly speed up the market introduction of UV-C LEDs,” said Crystal IS CEO Steven Berger. “Leveraging Sanan Optoelectonrics’ unique expertise in processing and packaging will allow us to focus on making the precision substrates required for efficient UV-C LEDs.” “The opportunity to partner with Crystal IS on a new LED technology will help Sanan Optoelectronics maintain its leadership position for the future,” said Sanan Optoelectronics CEO Simon Lin. "We expect downstream integrators of UV-based products will welcome an established supply train for this new product." The developed UV-C LEDs will operate at the optimal germicidal wavelength, and are ideal for use in water and air sterilization products. Initial applications will include portable and residential point-of-use systems such as cleantech alternatives to bottled water and in-home counter-top systems. The technology roadmap also includes industrial and municipal applications, where long-lasting, energy-efficient LEDs are ideal replacements for existing mercury-based light sources.
