A light source system for detecting oral has an illumination module and a filter module.A spectral range og light is illuminated from the illumination module and fitered through the filter module. When light of such spectral range is irradiated onto a diagnostic area,high chromatic difference and contrast existing between areas with pathological change and normal areas is employed to enchance correctness of diagnoses and operations.

Clinically, most regular light sources pertain to tungsten lamp, xenon lamp, halogen lamp, and the like. In contrast to the aforementioned light sources, light-emitting diode (LED) lamps are advantageous in less power consumption, high emitting efficiency, durability, environmental protection, compact size, adjustable light intensity, and abundant color gamut. As to biological medicine, there are plenty of related researches and equipment using various multi-spectral light sources to generate different biological images. Such biological images serve as references to medical personnel for determining if a diagnostic area has any abnormal pathological change.

在市場分析部分, LED照明技術的突飛猛進，不僅在照明領域大放光明，在醫療產業的應用上也是日漸普及。LED照明在醫療產業的應用可分三大類，依序為：醫療照明、醫療診斷與治療等，每個類型所需照明技術不盡相同,這類醫療照明產品，對光源品質與穩定性要求極高、允許誤差範圍小，且需符合國際規範與通過認證，才能維持醫療環境品質的穩定。當全球醫療費用不斷攀升，台灣健保嚴審與刪減醫療支出以杜絕浪費的趨勢下，國內外均醫療機構均積極推動早期健康檢查，盼在疾病發生初期便提前治療，降低後續與整體醫療費用,勢必成為市場主流方式。
