Predicting chromaticity shift in LEDs and SSL products
(originally aired November 27, 2018) Watch webcast (To skip registration, use this email: QS_color_shift_control@quarkstar.com) Lumen depreciation has been thoroughly studied in the solid-state lighting (SSL) world as the industry has sought to accurately predict the expected long lifetimes of LED-based products. But is a lighting product that significantly shifts in color or chromaticity over time still a viable product? Arguably, chromaticity shift can signal end of life just as easily as lumen depreciation in some applications. Industry experts have been investigating ways to quantify chromaticity shift for enhanced LED performance testing. This webcast will provide an overview of how the SSL design process can be enhanced by predicting chromaticity shift. Product developers and lighting specifiers will learn how such a data-driven method might be employed to help them choose products carefully and to confidently deploy SSL technology in color-critical applications.
