Abstract: A power saving welding helmet includes a helmet shell and a lens device. The helmet shell includes a mounting hole to contain the lens device. The lens device has an inner surface and an outer surface, and includes a magnetic sensor, a filter control unit, and a filter lens. The control logic module controls the filter lens according to magnetic signals generated by the magnetic sensor. The filter lens includes a first LCD panel and a second LCD panel respectively controlled by different control signals. Therefore, a refresh time of the first LCD panel and a refresh time of the second LCD panel do not synchronize. A welder does not feel the first LCD panel or the second LCD panel flashing, and the welding experiences this as consistent darkness.

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. Therefore, when the welding helmet is operated in an environment having intense light such as a welding arc, the single LCD panel will turn dark and lower its transmittance to block the intense light.
