In October 2009, Germany-based Evonik Industries and Taiwan-based Cristal Material Corporation have formed a new joint venture, Evonik Cristal Materials Corporation, to manufacture high-quality glass lenses for next-generation LEDs, which will marketed under the SavosilTM brand.
The LED lenses will be produced using Evoniks patented SiVARATM Sol-Gel technology, which allows glass lenses of consistent quality to be manufactured in any desired shape. The process recently received the Frost and Sullivan European Technology Innovation Award. Major applications will be high bright LED Lighting, concentrator photovoltaic, automotive lighting, and optics.
Ershien Tsai, chairman of Cristal Material Corporation, stated, "glass produced by the SiVARATM Sol-Gel technology is an ideal LED optics solution and is highly reliable." It also offers the phosphorous in the lenses outstanding protection against humidity and heat during operation And is thus ideal ideal for outdoor lighting.
