A kind of colorful luminous dipolar object light source generation device of optical dynamic therapy, to provide the light of a specific wavelength, it irradiates coated by one patient's selected position of what or the photosensitive drug of injection is to diagnose or treat, which includes that an at least luminous dipolar object light source generates unit and a light-emitting diode driving circuit. It includes a red light-emitting diode unit, a green luminescence diode unit and a blue light emitting diode unit that luminous dipolar object light source, which generates unit,. Wherein light-emitting diode driving circuit coupling one power supply circuit of what and luminous dipolar object light source generate between unit, to respectively drive the feux rouges, green light and blue light emitting diode unit, so that light light mixing Hou of the feux rouges, green light and blue light emitting diode unit sending, obtains the light of specific wavelength needed for optical dynamic therapy accordingly.一種光動力治療之多彩發光二極體光源產生裝置，用以提供一特定波長之光線，照射於一患者選定部位所塗覆或注射之光敏藥物以進行診斷或治療，該裝置包括有至少一發光二極體光源產生單元及一發光二極體驅動迴路。發光二極體光源產生單元包括有一紅光發光二極體單元、一綠光發光二極體單元及一藍光發光二極體單元。其中發光二極體驅動迴路耦接於一電源供應電路及發光二極體光源產生單元之間，用以分別驅動該紅光、綠光及藍光發光二極體單元，以使該紅光、綠光及藍光發光二極體單元發出之光線混光後，據以得到光動力治療所需之特定波長之光線。
