LASER MODULE CONTROL CIRCUIT

摘要

A laser module control circuit (100) is disclosed. The laser module control circuit (100) is provided with a laser module group circuit (110), and the laser module group circuit (110) is parallel connected with the first and the second control branch. The first control branch is provided with a first triode, and the second control branch is provided with a second triode. Collector electrodes and base electrodes of the first and the second triode are connected with the laser module group circuit (110) and the CPU respectively and emitter electrodes of the first and the second triode are grounded. The circuit controls the laser power output of laser emitters by means of controlling the conduction current of triodes. Thus the security is ensured.
