The study of RGB LED variable color temperature light source machine created by combined designs of lens

[[abstract]]目前手術房中所使用的光源機通常使用氙氣燈作為光源，雖然亮 度足夠，但消耗功率極高、同時產生紅外線波長。本研究使用LED 燈 源取代傳統燈源應用於光源機，針對聚焦LENS 的準直性與耦合LENS 的耦合性以及分光鏡的排列組合為設計重點，本研究光源機以白光色 溫作為設計基礎，且本研究不同於傳統光源機使用濾光片來改變色溫 的機制，藉由電壓及電流的調整改變RGB 三色LED 之發光比例，使 本研究之光源機調配之色溫範圍約可在3600K~10300K 之間做調整， 本研究所設計之光源機成果目前已超越市售醫療大廠Stryker L9000 Light Source 之LED 光源機，最後製作LED 光源機雛型，作為與模擬 結果比較，藉以驗證模擬數據與雛型結果之準確性，完成RGB 三色 LED 可變色溫光源機之研究。 關鍵字：LED、光源機、分光鏡、混色、氙氣燈[[abstract]]High Intensity Discharge, which is mostly used in the operation room, has enough brightness. But it will have produce high power consumption, and infrared wavelength. Instead of traditional light source, LED light source is used in the light source machine in this study, and the design focuses on the collimation of condenser LENS, the coupling of coupled LENS, and combination of Beamsplitter. This study is based on White Color Temperature,is used in the light source machine. Unlike traditional light machine using filters to change the color temperature, The study changes the luminescence ratio of RGB LED by adjustments of voltage and electric current to change the color temperature of light source machine. The color temperature can be able to make adjustments from 3600K to 10300K.The light source machine in this study has surpassed Stryker L9000 Light Source, the LED light source machine of medical manufacturers.Finaly, the prototype system of LED light source machine is done to compare with the simulated result so as to confirm the accuracy of the simulated data. After that, the study of RGB LED variable color temperature light source machine is completed. Keywords: LED, light source machine, Beamsplitter, color mixing、High Intensity Discharg
