The light sensor receives the light signal, and when the brightness detected by the light sensor is high, the control circuit controls the transmittance of the liquid crystal dimming film to be low (the change of the transmittance of the liquid crystal dimming film is generally called color change in the art), so that the wearer is prevented from being injured by sunlight irradiation and the like.
The existing electrochromic goggles have the following defects: 1. the light sensors are all arranged in front of the liquid crystal dimming film, so that after the liquid crystal dimming film is controlled by the control circuit to change color, the brightness of light rays entering human eyes is possibly too high or too dark, and the eyes of a wearer feel uncomfortable. For example, under a large sun, a person looks at a dark place, at this time, the light intensity of the environment received by the light sensor is still high, and the light transmittance of the liquid crystal dimming film is controlled by the control circuit to be reduced, so that a wearer cannot see the scene clearly. For example, under the large sun, the light intensity received by the light sensor is weak due to the fact that the electrochromic goggles are backlit or shielded, and at the moment, the light transmittance of the liquid crystal dimming film is kept unchanged, so that human eyes receive too high light intensity, and discomfort of the human eyes is caused; 2. the control circuit adjusts the voltage of the liquid crystal dimming film in a gear way, so that a screen flash is easy to occur when a color-changing critical value is triggered; 3. the circuit board is electrically connected with the liquid crystal dimming film through the electric wire, so that the assembly is inconvenient, the conditions such as wire breakage and the like are easy to occur, and the reliability of a circuit is affected; 4. the temperature difference between the inner side and the outer side of the goggles is large, so that the goggles are easy to fog, and inconvenience is brought to users.
