    摘要: 本論文主要是設計以LED為光源的室內照明燈具的光學系統,在本研究中主要依照使用的光源種類以及設計方式可以分為三種設計方案,分別為:中低功率照明燈具、高功率照明燈具、類面光源照明燈具。 中低功率照明燈具與高功率照明燈具皆是利用二次光學透鏡以折射與反射的方式來做燈具的設計。中低功率照明燈具使用的LED光源為中低功率LED,其功率範圍約為0.1~1w,以多顆排列的方式來增加燈具整體的發光強度。高功率照明燈具使用的LED光源為高功率LED,其功率大於1w,以單顆二次光學透鏡搭配微透鏡陣列結構來調整光線出光角度的分布,並且改善螢光粉LED的黃圈問題。 類面光源照明燈具主要設計有三個光學元件,分別為側發光透鏡、反射面以及微透鏡陣列板,利用側發光透鏡與反射面的搭配來增加光線出光的面積來減少單位面積的發光強,並且加入微透鏡陣列板來調整光線出光角度的分布。 在本論文的最後,量測實際成品與模擬數據做比較,以比較後的結果來證明本研究中的光學設計方法與模擬有一定程度的可信度。 The main objective of this thesis is to design the interior lighting system by using the LED source. According to the types of the source and the methods of the design, three kinds of designs including the middle/low power, high power, and quasi-surface lamps are proposed in this research. The second optical lens by the refraction and reflection are utilized in the designs of the middle/low power and high power lamps. The middle/low power lamps use the middle/low power LED with the powers within 0.1~1 W. A number of middle/low power LEDs develop the typical arrays to increase the overall luminous intensity. The high power lamps use the high power LED with the power greater than 1 W. By using the second lens and micro lens array to adjust the distribution of the exit light angle, the single high power LED with improvement of the yellow circular can be used efficiently. The side-emitting lens, the reflecting surface, and the micro-lens array are three important elements in the design of quasi-surface lamp. The side-emitting lens and reflecting surface can be used to increase the luminescence area and to decrease the luminous intensity per unit area. We also add the micro-lens array to adjust the distribution of the exit light angle to promote the efficiency. In the end of this thesis, the data of simulations are compared with the actual measurements of the lamps to prove the feasibility of the method of design and simulation.
