隨著LED製程提升後，整體成品尺寸的縮小，三原色混光LED已被大量應用在液晶螢幕背光模組、戶外及室內看板等領域。其中，三原色混光LED的CIE座標是評斷LED顏色是否符合客需的重要指標。為了確認三原色混光LED的CIE均一性及準確性，現行業界多是以實際試產的方式進行生產確認，其中需要試產後才能調整的參數包括:紅.藍.綠光晶片波長、亮度、發光均勻度、板材類型及供應商晶片等。不僅組合繁多且施行起來曠時費日。
本論文提出建立一套具準確性且成本低廉的三原色混光LED之CIE+波長模擬系統，可以縮短目前產品開發流程且減少所投入人力物力。除了提出模擬結果，本論文後半提出使用實際物料試驗，印證模擬系統的準確性，藉以證明此系統準確性。

With the LED manufacturing process to improve the overall finished size reduction, mixing the three primary colors of light LED has been widely used in LCD backlight, outdoor and indoor signage and other fields. Among them, the three primary colors of light mixing LED LED CIE color coordinates are judged important indicator of whether the customer needed. In order to confirm the CIE trichromatic LED light mixing uniformity and accuracy of the existing multi-sector approach is based on the actual pilot production confirmation, which parameters need to be adjusted in order to try postpartum include: red green blue chip wavelength, brightness, luminous uniformity, plate type and suppliers wafers. And implemented not only a combination of many days when Kuang up fee.

This paper presents a set of tools to build CIE accuracy and low cost of the three primary colors of light mixing LED + wavelength simulation system that can shorten the product development process and the current decrease in investment in human resources. In addition to presenting the simulation results, the present paper proposes the use of semi-realistic materials testing, confirmed the accuracy of the simulation system in order to prove the accuracy of this system.
