  • Patent number: 10908435
    Abstract: Provided is a pair of automatically photosensitive sunglasses with low power consumption, including a spectacle frame, two liquid crystal lenses provided thereon, a power supply module, a photosensor, a microprocessor, and a high-frequency charging and discharging bootstrap circuit, wherein the microprocessor comprises a low-frequency switching drive circuit for switching to a low or a high driving voltage of the liquid crystal lenses. The photosensor on the glasses triggers a switch by intelligently sensing the light change, and the lenses automatically become bright or dark accordingly, which is more convenient for users as it requires no manual operation. As the input power supply voltage is greatly increased by the high-frequency charging and discharging bootstrap circuit, simply a small and low voltage battery is enough to make it work.
