abstract = "A methodology analogous to a general lens design rule was proposed to step-by-step optimize the spectral power distribution (SPD) of a composite light-emitting diodes (LEDs) cluster. The computation is conducted for arbitrary SPD combination for the applications in radiometry, photometry and colorimetry, respectively. Based on the matrix computation, a spectrally tunable source is implemented to strategically manipulate the chromaticity, system efficiency and light quality according to all kinds of operational purposes. By the R/G/B/A/CW light engine with graphic utility interface, the cluster engine was experimentally validated to offer a wide-ranged operation in ambient temperature (Ta = 10°C to 100°C) with high color quality scale (CQS > 85 points) as well as high luminous efficiency (LE > 100 lm/watt) over the chromaticity point from 2800K to 8000K.",
