Abstract

The application provides a light module adaptive light-off control method and device, a light module and a storage medium. After an initial bias voltage of a modulation arm corresponding to a specified light channel of a light module at a current temperature is determined and applied to the modulation arm, a current is collected as a reference value. The initial bias voltage is adjusted by a debugging step, applied to the modulation arm and a new light monitoring current is collected. The debugging step is adjusted according to a comparison result of the reference value and the new light monitoring current. The new bias voltage is taken as a new initial bias voltage, the new light monitoring current is taken as a new reference value, the adjusted debugging step is taken as a new debugging step, and the step of adjusting the initial bias voltage by the debugging step is returned, so that the light monitoring current is minimized. The application can monitor the state of the light power of the light module in real time, continuously update the optimal light-off voltage of the light module according to the actual working condition, and always meet the light-off index.
