The working principle of the utility model is that when the glasses leg is opened, the power switch controller inside the glasses leg senses the magnetic field generated by the magnet inside the glasses leg. Under the action of the magnetic field, the power switch is turned on, and the power of the polymer lithium battery is input to the linear regulator. After voltage stabilization, the stable output voltage is sent to the low-power MCU, the DC boost module, and the light environment sensor to provide a stable power supply voltage for the three devices.

After power-on, the light environment sensor, DC boost module, and MCU installed in the middle beam of the frame start working. The MCU monitors the wearer's ambient light in real time to determine whether the wearer is in the day or night.

If it is at night, the night working mode is activated. The light environment sensor detects the ambient light data in front of the eyes in real time. When the ambient light is greater than the set light threshold, the liquid crystal lens is activated to work in mode 1 to block the strong light of the headlights in the opposite lane.

If it is daytime, the daytime mode is activated to monitor the external light intensity in real time, and adjust the darkness of the liquid crystal lens in real time according to the external light intensity to achieve the sunshade effect;

Specific introduction:

A high-precision light environment sensor LTR-308ALS is installed on the frame beam and the left end of the frame, mounted on the FPC soft cable, and connected to the control circuit board of the right temple through the soft cable. The MCU on the control circuit board monitors and reads the signal of the light environment sensor LTR-308ALS in real time after the wearer wears it (reading speed MS level). When the ambient light is detected to be less than the threshold Vth_M, it is determined to be night mode, otherwise it is day mode;

In night mode, the MCU performs the following processing based on the ambient light intensity it reads:

When the ambient light is greater than the set light threshold Vth1_N, the MCU outputs the working mode of the liquid crystal lens to mode 1, thereby blocking the strong light of the headlights in the opposite lane;

When the ambient light is greater than the set light threshold Vth2_N, the MCU outputs the working mode of the liquid crystal lens as mode 2, thereby achieving enhanced field of view clarity;

In day mode, the MCU performs the following processing based on the ambient light intensity it reads:

Determine whether to wear the watch in the car or outdoors based on the ambient light intensity and ultraviolet light intensity read;

When it is determined to be worn outdoors, the working mode 5 is activated to adjust the darkness of the lens in real time according to the calculated light intensity, so that the color changes between 10% and 75%;

When it is determined that the wearer is wearing the device in the car, Mode 1, Mode 4, and Mode 5 are activated in real time according to the calculated light environment.

Among them, the setting values of Vth1 and Vth2 need to be set according to the transparency of the frame in front of the ambient light sensor LTR-308ALS, and the value range is between 1-20LUX, and the value range of Vth_M is between 1-100LUX.
