摘要

由於LED發光面積集中、光源具指向性等特點，使LED燈具容易衍生干擾現覺的眩光。本文以失能眩光與不舒適眩光的評估爲目標，建立以眼球模型爲基礎的失能眩光模擬平台，並建立現覺舒適度測試環境與實驗流程，探討以LED檯燈照明時，受試者舒適閱讀所需之背景光強度與對比。

Due to the distinct characteristics of LEDs from conventional light sources, such as the compact source size and directional illumination, LED lamps are more probable to induce glare that disturbs human's visual perception. In order to evaluate the disability glare, an optical simulation platform was established based on a human-eye model. A discomfort-glare evaluation procedure was developed to assess visual comfort when reading with a LED desk lamp. Experiments were performed to find the appropriate illuminance combinations provided by the LED desk lamp and ambient lighting based on visual comfort.
