摘要

傳統生醫檢測所使用的燈源為氙燈，其頻譜寬且各波長相對強度約為一致。然而礙於氙燈壽命短，耗費能量大，LED本身壽命長、穩定度高、耗能小，而且從紫外光到紅外光具有多種波長選擇性，因此本論文將多波長發光二極體利用混光技術製作一全頻譜光源，透過光在各個光學元件的穿透、反射與散射現象，破壞發光二極體相互之間的干涉現象，完成一寬頻譜且相對光強約一致的白光燈具。

Traditional light source for bio-medicine investigation is xenon lamp which has broadband spectrum and the relative intensity of each wavelength is consistent. Due to the lifetime is short and energy-consuming of the xenon lamp, this study used color mixing from multi-wavelength light emitting diodes (LEDs) to replace the xenon lamp as a light source since the LEDs have variable wavelength from UV to IR, long lifetime, and low energy, consumption. The light interference from LEDs may be destroyed through the light transmission, reflection and scattering at each optical components. Finally, a white light source with broadband spectrum and nearly light intensity was successfully built.
