本研究之目的在設計出一種輕型LED手術燈。主要是將近年來廣為使用在指示燈、裝飾燈及汽車尾燈的光纖燈條以及常被用來耦合光纖之玻璃球等材料作為手術燈之光學元件來設計手術燈。設計基本原理為透過在外型設計或在元件表面上使用特徵結構將LED光源改變其原本光路，或利用特徵結構破壞光纖內之全反射狀況而使光線改變方向從另一側射出。本研究將藉由TracePro光學模擬軟體來模擬光線在光學元件內的傳播路徑，並利用TracePro內建的幾何優化器，將幾何模型與特徵結構進行參數化設定，來優化幾何模型與特徵結構，使其達到最佳效果。再透過TracePro進行光源排列設計，使光線達到觀察面時，符合手術燈規範IEC 60601-2-41的基本要求。最後將模擬所得之模型建構出來，並依據手術燈規範IEC 60601-2-41做中心最大照度、光野直徑、無影度、照傷深度、照明深度之實驗來驗證本研究手術燈的模擬與優化設計。

The main purpose of this study is to design a lightweight surgical operating lamp. In recent years, optical fibers and ball lens have been widely applied as light sources deflectors in the design of indicator lights, decorative lights, and taillights of automobiles. Through the structure of the optical fiber, the V-shaped features on the surface of the optical fiber or ball lens, the direction of LED light can be changed in its direction which is suitable for surgical light. That is, different structure of optical elements may alter the path of light, while the features can also prevent the total reflection of LEDs light and change the angles of incidence light.
In the current study, the TracePro, the optical simulation software is used to simulate the propagation path of the light within the optical element. In fact, in order to optimize the setting of optical element geometry model, optical fiber’s feature structure and the built-in Geometry Optimizer are employed, by coupling with specific parameter approaches to achieve the best results. Furthermore, complying with IEC 60601-2-41, the standard requirements for surgical operating lamps, the study also employs the TracePro to do the fiber array design, ensuring that the light can reach the observation surface properly.
Finally, a model of a surgical operating lamp is established by doing the simulation, while the experiments of Central Illuminance, Light Field Diameter, Shadow Dilution, Cavity Penetration and Depth of Illumination are conducted in accord with IEC 60601-2-41 standards to verify and validate the results of this research study.
