TT electronics Optek Technology has just announced its new multi-chromatic tuned light engines to provide lighting designers with highly consistent LED color matching capabilities. The company’s chromatic tuning process produces solid-state lighting solutions with high module-to-module consistency, such that differences in color temperature of each light engine are indistinguishable to the human eye.

The standard measure for distinguishing between differing chromaticity is the 4-step MacAdam's ellipse. A reference chromaticity point on MacAdam's 1931 correlated color temperature (CCT) chart represents a given color value, and a 4-step ellipse around that point indicates color variations that are indistinguishable to the human eye.

"We employ a multi-chromatic tuning process to generate white lighting solutions within a single 4-step MacAdam's ellipse, guaranteeing that all light engines built to these specifications produce consistent color," said Roland Chapa, vice president of optoelectronic integrated solutions for Optek Technology.

"Whether for indoor or outdoor use, light engines that produce slightly different color temperatures are extremely displeasing to the eye, making tuned white light critical to architectural lighting and general illumination applications," Chapa continued.
