Embodiment Construction
[0031] The discoloration control device of the liquid crystal sunglasses of the present invention is composed of a liquid crystal lens, a control module and a photoelectric conversion battery.
[0032] The photoelectric conversion cell is a solar cell module, the solar cell module is a sequence composed of a plurality of amorphous silicon cells, a sequence is composed of 4 to 8 individual cells, and the size of the module is about 10 mm long and 5 mm wide. Other types of solar cells are likely to be suitable alternatives, however, the solar cells may need to be sized smaller or larger to obtain the desired output power.
[0033] The input signal of the solar cell is sunlight, and the output is the control voltage signal;
[0034] The central wavelength of the amorphous silicon solar cell used in this example is about 650 nanometers, and the peak of the spectral response is in the range of visible light.
