A kind of luminous dipolar object light source selection device with what introscope, system includes a bottom plate, one sliding rail, one light source generates unit, one displacement control unit and a coupling light element, the sliding rail is arranged on the what bottom plate, the light source generates on unit setting what sliding rail and includes a substrate and the one first light-emitting diode mould group and one second light-emitting diode mould group that the what substrate side is arranged, the displacement control unit generates unit with the light source and connect, which is arranged the what bottom plate and the adjacent what light source generates unit. Light source generation unit is controlled by the displacement control unit to move on the sliding rail, makes the coupling light element that can correspond to what the first light-emitting diode mould group or the second light-emitting diode mould group, and carry out the movement of coupling light, and then reach the effect of light source switching selection.一種用於內視鏡的發光二極體光源選擇裝置，係包含一底板，一滑軌，一光源產生單元，一位移控制單元以及一耦光元件，該滑軌設置於該底板上，該光源產生單元設置於該滑軌上且包含一基板以及設置於該基板一側的一第一發光二極體模組與一第二發光二極體模組，該位移控制單元與該光源產生單元連接，該耦光元件設置於該底板且相鄰於該光源產生單元。藉由該位移控制單元控制該光源產生單元在該滑軌上移動，使該耦光元件可對應於該第一發光二極體模組或該第二發光二極體模組，並進行耦光之動作，進而達到光源切換選擇之效果。
