26 November 2002 Chromaticity and color temperature for achitectural lighting
Author Affiliations +
HBLEDs bring a new dimension to architectural lighting design: color. Compared to traditional "white" light sources such as fluorescent and metal halide lamps, HBLEDs offer lighting designers unprecedented control over color temperature and lamp chromaticity. This raises two important questions: 1) How should the correlated color temperature metric used by lamp manufacturers be applied to HBLED-based light sources; and 2) What are appropriate limits on chromaticity variances for LED clusters and arrays? The answers to these questions will influence the acceptance of HBLEDs by architectural lighting designers.
