In　this　paper,　we　calculated　the　color　matching　of　white　LEDs　based　on　phosphor　converted,　two　primary　colors　and　three　primary　colors　according　to　colorimetry.　Many　color　combinations　whose　chromaticity　coordinates　deviate　from　the　equal　energy　white　point　(1/3,　1/3)　not　more　than　0.5%　have　been　obtained.　We　used　luminous　efficacy　and　color　rendering　as　standards　in　the　evaluation　of　them　by　a　program　simulation　and　obtained　the　best　combinations　which　supported　by　experiment.
