摘要:	本論文中，使用Cree高功率複晶LED，並根據中場擬合法建立精準的LED之光學模型。依據精準的光學模型，我們設計一款以LED為光源的低眩光投射燈具，有效的將眩光程度降低。並分析此款燈具對光源的各項容忍度包括位移以及旋轉等參數。最後製作出工程版燈具，由實驗中驗證了模擬準確度。將此低眩光投射燈具與另一款LED比較眩光指數分析，並由計算結果證實，低眩光投射燈能有效降低眩光的程度。 In this thesis, we apply a multi-chip and high-power LED to design a low-glare lamp. According to the mid-field algorithm, we have established an accurate LED optical model. Base on the light source model, we design a projection lamp with the low-glare property. By analyzing the tolerance of the lamp, we find it has large tolerance in shifted and tilted variation. Then, we verify the accurcy of the simulation results with the proto-type sample. Finally we confirme that low-glare projection lamp can reduce the glare level by calculating the veiling luminance of the low-glare lamp and compare it with another LED lamp.
