手提式LED量測系統分析

發光二極體(light emitting diode, LED)將成為下世代照明的主流。隨著LED的發光效能及演色性逐漸提升，為了配合LED技術的快速發展，需要更積極去推動LED照明產品的標準制定。由於標準制定為市場開拓之先決條件，而量測技術為公平評估LED性能之重要關鍵，需要建立一套標準且完善的量測技術，才能夠獲得具有可信度及精確的數據，以提供國內廠商開發產品之參考和比較。本論文研究目的為設計並規劃出一套「手提式LED量測系統」，藉由積分球、光譜儀等等的硬體設備獲得所需要的光譜資訊，並透過CIE技術文件公布的計算流程及方式，計算出待測LED的光源資訊，且手提式功能增加量測的方便性和機動性，可以隨時隨地測量LED特性。本論文將利用軟體MATLAB撰寫量測系統的運算程式及人機介面，並與廠商開發的量測系統比較計算結果及驗證所設計光學量測軟體的精確度與可信度。比較結果的相對誤差幾乎都是1%左右或是更小，但仍有誤差大至10%甚至40%，不過經由驗證所設計的軟體量測結果較符合事實，所以大致上誤差都在合理範圍內。台灣是LED主要生產國之一，所以對於研究如何更有效、精確的量測LED是改善LED生產和量測上誤差的重要議題。因此，在未來LED量測技術的開發將成為一門不可被忽略的科學。

Light emitting diodes (LEDs) will become the mainstream of lighting of next generation. With LED efficacy and color rendering index is gradually enhanced, in order to follow the rapid development of LED technology, the standards of LED lighting products need to be promoted actively. Standard is the conditions precedent for market development, and measurement technology is the important key of fairly assessing LED performance. The standard and perfect measurement technology needs to be established, and the credible and accurate data is obtained, and reference and comparison of Product development is provided for domestic manufacturers. The research purpose of this thesis designs and plans a set of 「Portable LED Measurement System」, and the required spectral information is obtained with integrating sphere、spectroradiometer, and other equipment. The test LED source information is calculated with calculation procedures and methods that CIE technical documents published. In addition, portable feature increases convenience and mobility of measurement, also LED characteristics can be measured anywhere. In this thesis, computing programs and HMI are written using MATLAB, and the results is compared with the results of measurement system that Company develops, and accuracy and reliability that optical measurement software is designed are verified. Relative errors of comparative results are almost about 1% or lower, but there are still errors about 10% or even 40%. However, measurement results of software of design correspond with the facts by verifying, so errors are generally within reasonable ranges. Taiwan is one of major productive countries of LED, so researching how to measure LEDs effectively and accurately is important issues of improving LED measurement errors. Therefore, the development of LED measurement technology will become a science that can’t be ignored.
