A light source of a digital end point blood flow analyzer.It includes a plurality of luminescent bodies with at least one set of opposite rings arranged on the inner side under the digital microscope.A circuit board for electrically connecting a control chip and a light-emitting body；One end of the power signal cable is connected to the circuit board telecommunication.And a computer with one end connected to the other end of the power signal line；Using computer programs,Through the selection of key trigger times,In order to control at least one group of opposite illuminants to open and close at different angles,In order to control the incident angle of the illuminant,A digital microscope was used to record the image of fingernails coated with silicone oil.Until the set of opposite illuminants that do not produce reflections is turned on.一種數位式末稍血流測定儀之光源，其包括複數個至少一組對立環設於數位式顯微鏡下方內側之發光體、一具控制晶片與發光體電性連接之電路板、一端與電路板電訊連接之電源訊號線，以及一端與電源訊號線另一端電訊連接之電腦；利用電腦之程式，透過按鍵觸發次數之選擇，以控制其中至少一組對立之發光體作不同角度之啟閉動作，藉以控制發光體之入射角，採用發光體之入射角為電腦之螢幕秀出數位式顯微鏡攝錄塗有矽油之指甲影像，直至不會產生反光之該一組對立發光體開啟。
