Endoscope illumination device and endoscope system

The invention discloses an endoscope lighting device and an endoscope, and belongs to the technical field of endoscopes. The endoscope lighting device comprises an excitation light source used for emitting excitation light; the first light guide component is coupled to the excitation light source and is used for guiding the excitation light into a light-emitting conductor component; the light-emitting conductor component is provided with a light-emitting surface for emitting the exciting light, and the light-emitting direction of the light-emitting surface faces the forward direction and the lateral direction; and the wavelength conversion layer is arranged on the light-emitting surface of the light-emitting conductor component and is used for converting at least part of the exciting light into excited light of which the wavelength is different from that of the exciting light. According to the endoscope lighting device, the problem of overexposure of the central area of the acquired image can be avoided. 本申请公
