Commercial LED lighting offers inherently high energy efficiency and reliability benefits. New developments are also seeking to provide commercial users with increased optical efficiency and better light uniformity.
Intematix Corporation, manufacturer of phosphor solutions for LED lighting, collaborated with SABIC's Innovative Plastics business to create the ChromaLit Linear LED for the lighting industry. The LED uses SABIC's Lexan Lux resins.
Linear light sources are widely used for commercial and industrial lighting applications worldwide. Office lighting and other commercial applications pose challenges for use of white LEDs because of the need to diffuse the point sources, reducing system efficacy. The new ChromaLit Linear system was developed to provide naturally uniform, high-quality light with conversion efficacy of up to 215 lumens per radiant watt or up to 163 lumens per system watt when used with the most efficient blue LEDs available.
Remote phosphor is a lighting system technology using a phosphor component separated from the blue LED energy source. The independent phosphor emits light when excited by blue light. When the phosphor has been separated from the energy source it results in better lighting uniformity and consistency. Intematix selected Lexan Lux transparent, diffusion, and reflective grades for their efficiency and flexible processing capabilities. In addition, the LEXAN LUX base material provides a UL94 flame rating of V0.
"In addition to being more efficient, the new LED system can be both extruded and injection molded," said Venugopal Koka, Director of Electrical Industrial and Lighting Marketing for SABIC's Innovative Plastics business.
Mark Swoboda, CEO of Intematix, expects new remote phosphor solutions to emerge as it draws on it's partner's advanced thermoplastics expertise. "Our experience has demonstrated that bringing our two companies' innovations together results in ground-breaking products that accelerate market adoption of LED-based lighting systems," he said.
The two companies plan to continue their collaborative efforts, and expect their complementary expertise to lead to development of new applications, technologies, and materials that can hasten the commercialization of new LED products.
