本文應用光場程式化技巧，研究自建數值模擬程式及流程，設計白光LED以及紅、綠、藍三色LED兩種直下式背光模組，著重於LED封裝結構設計、背光模組光場數值化技術以及LED燈箱排列均勻度分析計算，可以快速設計並且分析一直下式背光模組，達到高均勻度的目的，一般光學模擬軟體其光學追跡進行光路運算，模擬一組燈箱搭配擴散板，追跡其中所有光路是十分複雜且耗時的，但用本文光場數值化的方法，模擬一組32吋直下式背光模組均勻度分佈，只需簡化成模擬單顆LED的光型分佈，再進行迴歸曲線的擬合疊加，如此可以在半小時內即完成一組32吋燈箱光分佈的模擬，大幅減少了模擬設計時間。模擬出的數據也和光學模擬軟體僅有百分之五的平均誤差，本文應用此流程設計兩種直下式背光模組，依據所需的條件進行排列設計計算，設計出白光LED背光模組亮度均勻度達95.6%，紅綠藍三色LED背光模組亮度均勻度達92.84%，達到準確並且有效率的設計方式。 Application of field value programmable simulation techniques to establish programs and processes. Design of both white LED and R-, G- and B-LED tow kind of backlight module. Focus on the LED package structure and the value of field technology and LED light box uniformity analysis and calculation. It can quickly design and analysis the backlight module. The purpose of achieving high uniformity. General optical simulation software for the optical light path tracing is very complex and difficult. Simulate a light box with diffuser in which all of the optical path is very time-consuming. Simulation of a group of 32-inch backlight module require so many times. But the value of field with this method, only simplified simulation of single LED light type distribution. So that to complete the lightbox simulate only in half an hour. The simulated data and optical simulation software, the average error of only 5%. Application of this process design two backlight module. White LED backlight to achieve uniformity of 95.6% in brightness. Red, green and blue LED uniformity of can reach 92.84% in brightness. To achieve accurate and efficient design.
