Abstract

The invention relates to a mixed photonic lock structure having intelligent identification and a method thereof. It comprises a mixed photonic key inserted into a mixed photonic lock body. A power supply unit of the mixed photonic lock body supplies the required power to the mixed photonic lock body and the mixed photonic key. An infrared (IR)-LED in the mixed photonic lock body emits a corresponding signal to an infrared photo detector (IR-PD) in the mixed photonic key. When the comparison conducted by a signal comparison circuit of the mixed photonic key matches, a RGB-LED emits a light signal password to a RGB PD of the mixed photonic lock body to control the lock to unlock after the comparison conducted by a signal comparison circuit of the mixed photonic lock body matches.
