Covestro at Strategies in Light 2016: Discusses Benefits of Unique PC for LED Optics

Published on 2016-03-01. Author : SpecialChem

PITTSBURGH -- LED technology has been rapidly advancing, resulting in reduced costs and better performance that continues to spur market demand for LEDs. Industrial, commercial and residential lighting applications are increasingly turning to LED technology due to its superior energy efficiency, long life spans and excellent durability. New materials - such as polycarbonate specifically developed for LED applications – play an important role in improving LED performance and quality.

Polycarbonate materials are utilized for LED optic and lens applications, especially when heat, flame, or impact resistance is required. Conventional transparent polycarbonate can show signs of hazing and yellowing when exposed to intense LED radiation in the 400-500 nanometer (nm) range and long-term direct outdoor sunlight exposure.

To overcome this challenge, unique grades of Makrolon® LED polycarbonate from Covestro should be used to extend product longevity and minimize absorption in wavelengths between 400-500 nm. Ultraviolet (UV) yellowing during outdoor exposure is mitigated by Covestro’s AURATM UV infusion process. In this process, molded parts are immersed in a solution that penetrates into the surface of the plastic. The resulting parts exhibit reduced yellowness similar to acrylic after UV exposure.

Nicolas Sunderland, principal scientist, electrical, Polycarbonates, Covestro LLC, will discuss this in his presentation: “Polycarbonate LED Optics: Enhanced Stability for Long Term Performance” at 2:15 p.m., Thursday, March 3, during Strategies in Light 2016 in Santa Clara, California.

Strategies in Light attendees are invited to attend the presentation and stop by Covestro’s booth (#607) to learn more about the materials, technical services and technologies Covestro offers for LED lighting applications
