We proposed a general design procedure included six steps that can be analogous to the conventional lens design process to optimize a LEDs cluster with high color rendering capability and good efficiency for a desired range of color temperature. The concept was illustrated via a cluster composed of red/green/blue/amber/cool‐white (R/G/B/A/CW) LEDs. The result shows the R/G/A/CW cluster can be applied to the range of color temperature from 2600K to 8500K with the color quality scale > 80 points and with the averaged luminous efficiency of 97% cluster's limit.
