Medical ultraviolet light electronic endoscopy light source device

The invention discloses a medical ultraviolet light electronic endoscopy light source device, which comprises a lighting part, and a lens part and a back end control system which are connected with the lighting part; the lighting part comprises an annular ultraviolet LED, a lens group and an optical fiber which are arranged in order; the lens part comprises an optical objective lens and a color image sensor which are arranged in a spherical transparent outer shell, wherein the tail end of the optical fiber is located in the spherical transparent outer shell and irradiates ultraviolet light tothe surface to be tested through the outer shells of the optical objective lens and the lens; the color image sensor collects the reflected ultraviolet light and outputs a simulated signal to the backend control system to recover the picture. The light source of an endoscope adopts the ultraviolet LED, and lights and stimulates the surface of gastrointestinal tract issues in a biological body; compared with an ultraviolet
