  • Patent number: 10663779
    Abstract: A welding helmet includes a helmet shell and a lens device mounted on the helmet shell. The lens device includes a filter control module and a single LCD panel. The logic control module controls the transmittance of the single LCD panel based on a sensed light signal and a shading-level signal designated by a user.
