本研究的研究目標為進行手術燈設計時考慮LED 手術燈製造公
差對於光學表現之影響。手術燈乃醫療上極為重要之照明器材，目前
手術燈以LED 為光源為主流產品，其主要原理為將LED 光源透過透
鏡與反射杯將光線照射至指定位置。目前市售手術燈極為笨重，因此
開發輕型手術燈無論在成本與設計上皆較市售手術燈更有優勢，但也
意味著整體尺寸要小，所以製造公差顯得極為重要。本研究首先利用
TracePro 光學模擬軟體來模擬具有球型透鏡反射杯的輕型手術燈設
計之光照度，其後分析球透鏡加工誤差對光照度的影響，並利用實驗
驗證反射杯以一般精度加工與精密加工對於LED 手術燈照度之影響，
從而找出製造公差對於光學表現之影響。最後，將對反射杯模型與特
徵結構進行重新設計，並設計手術燈之機構及光源排列，優化製造公
差的影響，並符合手術燈規範IEC60601-2-41 的基本要求。

The main purpose of this study is to consider the manufacturing
tolerance effect on the surgical light design. Surgical light is one of
important lighting equipment of medical devices. The main principle of
surgical light is the LED light source through lens and reflector cup to
restrain the light to a specified location. The surgical lights available in the
current market are extremely bulky. Therefore, developing lightweight
surgical lamp has the advantage of the low cost and the lightweight, which
is drastically, exceeded the traditional surgical lamp. Hence, all the
structures of the lightweight surgical lamp must be smaller than that of the
traditional lamp; the optical device is always sensitive to the accuracy of
the optical component. Therefore, to understand manufacturing tolerance
effect on the lighting becomes an extremely important.
In this study, TracePro, an optical simulation software, is employed to
simulate the illumination of lightweight surgical lamps which used the
spherical lens as the lens to deflect the light from LED. Next, analyze the
influence processing error of spherical lens on the lighting, and the
experiment to verify the difference between traditional processing and
precision processing of reflective cups on the illumination was developed.
Thereby, hope this study can find out the effect of manufacturing tolerances
on the optical performance.
Finally, the reflector cup model and feature structure to achieve the
best results are developed, which reduces the possibility of manufacturing
tolerance effects. At the mean time, design the mechanism of the surgical
lamp and arrangement of the light source to minimize the influence of
manufacturing tolerances, was comply with IEC 60601-2-41.
