An eye protection device for a welding mask or the like includes a welding activity detection circuit that is configured to detect welding activity, and a filter driver that controls an optical filter to be in undarkened and darkened states. The filter driver is configured to (i) provide a slower and/or gradual opening of the filter, (ii) insert a user-selected delay and/or gradient between the end of welding activity and the opening of the filter, and/or (iii) cause variation of light transmission values of the filter between a darkened state and an undarkened state based on varying brightness detected by a brightness sensor during transition of the filter from a darkened state to an undarkened state.

An illuminated welding helmet system for selectively illuminating a darkened area during welding operations includes a welding helmet that may be worn during welding and the welding helmet includes an auto lens. A light unit is coupled to the welding helmet and the light unit selectively emits light outwardly from the welding helmet thereby facilitating a darkened area to be visible. The light unit is in electrical communication with the auto lens. Moreover, the light unit is turned on when the auto lens does not detect light and the light unit is turned off when the auto lens detects light.

Protective headgear with a curved switchable shutter and curved front and rear cover plates and including at least two antireflective layers.

An auto darkening mask which has a weld cap and a filter mechanism, wherein the filter mechanism includes a lens module, a connecting line and a regulating system; and the weld cap is provided with a visible window. The lens module is assembled inside the weld cap and is opposite to the visible window of the weld cap. The regulating system protrudes out of an outer side of the weld cap and is connected with the weld cap, and the lens module is connected with and controlled by the regulating system through the connecting line.

A protector for a welder includes a main body configured to cover a face and eyes of an operator; a darkening filter arranged in a front side of the main body and configured to protect the eyes of the operator; an image generator arranged in the main body and configured to generate image light; an optical path bender configured to change a proceeding path of the image light; and a combiner configured to generate a virtual image on an outer portion of the main body by projecting the image light, and arranged adjacent to the darkening filter.

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.

A method of improving a welding helmet through adding a light shield to selectively cover the light sensor of the welding helmet's window, thereby preventing sensor-based deployment of the automatic window darkening system when the wearer is performing non-welding activity in need of a fully transparent window. The light shield is moveable to an inoperative position so that the automatic window darkening system works as intended when the wearer is welding.

A welding protection device (10) comprises a shield body (12), an automatic darkening filter (13) insertable in the shield body, and a haptic sensing unit to sense a touch pattern occurring on at least a first portion of the shield body or automatic darkening filter assembly. Upon sensing of a touch pattern, a user definable command is executed. This user definable command can place the welding protection device in a specific operational state.

This application relates to a welding information providing device. The device can provide a high-quality image that can easily identify a welding surrounding environment in addition to a portion adjacent to welding light by synthesizing images obtained under various photographing conditions. The device can also improve welding quality by providing an efficient guiding to an operator with respect to a current welding operation state. The device can include a cartridge unit that is located on a main body and selectively shields welding light, at least one camera unit that faces outward and obtains a welding image frame of a welding operation, and a sensor unit that detects a degree of light in at least a welding operation area. The device can also include an image display and a processor that provides a welding image generated through the welding image frame to the image display unit.
