Abstract: An electric illumination arm mechanism based on a slit lamp microscope is characterized in that it comprises a lifting arm, an illumination arm and an electric drive mechanism; The electric drive mechanism is fixed on the connecting part of the lifting arm and is used to drive the illumination arm to swing to realize the electric swing of the illumination arm. The invention has the following beneficial effects: first, realize the electric illumination arm function of the slit lamp microscope; Second, electric control can improve the accuracy of the swing angle of the illumination arm, which is conducive to improving the detection efficiency. Third, it is compatible with the manual illumination arm function. Fourth, it is convenient to realize intelligent operation and remote operation of the whole slit lamp microscope.
