Lighting Quality Metrics – CIE and IES Recommendations on Flicker, Color Rendering and HCL
Constant changes in LED technology allow for more and more sophisticated and customer oriented solutions. When designing and offering new lighting products we need to focus on customer demands but we should also pay attention to the minimum technical and biological requirements, since lighting has a major impact on humans. The human centric lighting concept takes into consideration many different aspects of lighting technology along with biology. Better color perception, lower impact of light pulsation and proper tuning of color temperature and illumination level is in line with the human centric lighting concept.
What are the unbiased criteria for the quality of human centric lighting? How to evaluate which products and installations are better for humans? This presentation will provide a comprehensive overview of up-to-date lighting quality metrics which are currently being introduced or have already become a new standard. From color rendering of IES TM-30 and the new CIE Color rendition through optical flicker and SVM suggested by Philips to the new Circadian Metrics proposed, we will share our experience with measurement instrumentation and procedures. We will also present and explain how to understand new metrics for product evaluation with human centric lighting in mind.
