| description | The optical code lock of the present invention includes: a lock body, a key unit, a light sensor, and a control unit. The lock body has a plurality of adjustment units and a light adjuster. The light adjuster can generate several sets of PWM Signal, the plurality of adjustment units can adjust the plurality of sets of PWM signals; the key unit has an illuminator, the illuminator has a plurality of LED light sources, and after receiving the plurality of sets of PWM signals, it emits a light with a predetermined color temperature; the light sensor Convert the received light into an optical signal and transmit it to the control unit. The control unit stores a predetermined optical signal. When the key unit is inserted into the key hole of the lock body, and the adjustment units are operated to generate an unlocking light, When the control unit compares the optical signal of the unlocking light with the predetermined optical signal, the lock can be opened. |
