Automatic sensitization sunglass of low -power consumption

The utility model discloses an automatic sensitization sunglass of low -power consumption, include the spectacle frame and establish two liquid crystal lens, power module, photosensor, microprocessorand the high frequency charge -discharge boost circuit on the spectacle frame, microprocessor switches over drive circuit including the low frequency that is used for switching over the high low -voltage of liquid crystal lens drive. Change through setting up the photosensor intelligence sensing light on glasses comes the autotrigger switch, makes the lens take place intensity changes, removes user manually operation from, facilitates the use. Through high frequency charge -discharge boost circuit, effective power supply voltage who improves the input only needs to connect small -size low -voltage battery and can realize work, relies on the low frequency to switch drive circuit simultaneously, reduces liquid crystal lens driving voltage's frequency by a wide margin to show reduction glasses consumption, realizing
