  • Dimming method and dimming device for dimming glass, and dimming glass system
    Patent number: 11698543
    Abstract: The present disclosure discloses a dimming method for a dimming glass, including: in response to a dimming level selected from a user, obtaining a light transmittance value corresponding to the selected dimming level according to a corresponding relationship between dimming levels and actual light transmittance of the dimming glass; obtaining a dimming voltage value corresponding to the light transmittance value according to a corresponding relationship between the actual light transmittance and dimming voltages of the dimming glass; and adjusting a voltage applied to the dimming glass to the obtained dimming voltage value, wherein the corresponding relationship between the dimming levels and the actual light transmittance of the dimming glass is dividing an adjustable range of the actual light transmittance of the dimming glass to obtain the actual light transmittance corresponding to different dimming levels. The present disclosure improves dimming effect of dimming glass.

  • UNMANNED AERIAL VEHICLE AND DIMMING DEVICE FOR A SWITCHABLE GLASS
    Publication number: 20220074264
    Abstract: A dimming device for a switchable glass includes a third wireless communications component and a third controller. The third wireless communications component is configured to establish a communications connection to a master computer and a second unmanned aerial vehicle, and to receive a target transmittance sent by the master computer and a transmittance of a switchable glass to be detected sent by the second unmanned aerial vehicle. The third controller is configured to adjust a voltage applied to the switchable glass to be detected when the transmittance of the switchable glass to be detected is inconsistent with the target transmittance, so that the transmittance of the switchable glass to be detected is consistent with the target transmittance.
