摘要

本研究探討市售白光MR16-LED實驗樣本之屬性綜合評量。首先以積分球及配光曲線儀等儀器量測各樣本之投光範圍、平均照度、中心點照度、均勻照明平均照度、均齊度、光通量、燈具發光效率、耗能、光源演色值、金額參數十組照明屬性。其次，這些資料以屬性評量法（Multidimensional Preference Analysis, MDPREF）進行屬性聯合空間座標圖繪圖及比較。其評量結果，如前三名樣本中，光效、流明數等照明屬性較佳，其演色性未必呼應；此現象以暖白光LED（3000K）較冷白光LED（6000K）顯著。除此，三顆LED晶粒封裝的較單顆LED晶粒有優良的照明屬性。

The produce of the domestic LED is currently leading the world. The LED, which is directly packeted to be the white light MR16 LED lamps devices still pose a alienation to the public who get no knowledge about it. Althought it owns the abundant of superior parameter, the public is hardly to have the objective solutions to these sophisicated and mutiple parameters due to the low proportion of the utilization.Therefore, a brief analysis tool is quite important.
The Research takes the 16 types of white light MR16-LED as the experiment samples. By using the optical apliance to measure the ten groups of“ Project Area”, “Average Illuminance of the Project Area”“Average Illuminance of the Wall Area”，“Uniformity Ratio of Illumiance”，“Luminous Flux”，“LE:Lm/W”，“Energy”，“Color Rendering Index” and “Cost” , plus using stastistical method of (multidimensional scaling analysis, MDS) to appraise each illumination types. Such kind of results was indicated by union space graph and was changed into various lamps to different types of the graphic standing, providing professional design and simplified analysis mode. The final result of this analysis pattern manifests that performance of LM /w and Luminous flux can have a high position but bad in color rendering index. Under this circumstances also shows that warm white light LED(3000K) is much remarkable than that in white light LED.
