Problems solved by technology

However, when the welder is not working, the welder may not clearly see the surroundings through the dark lens.
However, since the viewing lens is controlled by alternating current (AC) signals and a voltage level of the AC signals may be changed with time, the viewing lens may flash when the voltage level of the alternation ...

Embodiment Construction

[0031]With reference to FIG. 1, the present disclosure is a power saving welding helmet 1. The power saving welding helmet 1 may reduce power consumption to save more electric power.

[0032]The power saving welding helmet 1 includes a helmet shell 10 and a lens device 20. The helmet shell 10 includes a mounting hole 11. The lens device 20 is mounted in the mounting hole 11 of the helmet shell 10.

[0033]With reference to FIGS. 2 and 3, the lens device 20 has an inner surface 201 and an outer surface 202, and alternatively includes a solar panel 21, and a light sensor 22. The lens device 20 further includes a magnetic sensor 23, a filter control unit 24, and a filter lens 25.

[0034]With reference to FIG. 5, in one embodiment, the lens device 20 may not include the solar panel 21, and the light sensor 22, but may include the magnetic sensor 23, the filter control unit 24, and the filter lens 25. The filter control unit 24 is electrically connected to the magnetic sensor 23, and the filter ...

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.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to a welding helmet, and particularly to a welding helmet having a function of automatically adjusting light transmittance.2. Description of the Related Art[0002]A welder may wear a welding helmet when working. The welding helmet may protect the eyes, face, and neck of the welder from flash burn, ultraviolet light, sparks, infrared light, and heat.[0003]A conventional welding helmet may have a dark lens, and the welder may clearly see a welding position through the dark lens. However, when the welder is not working, the welder may not clearly see the surroundings through the dark lens. Hence, the welder may take off the welding helmet from a position in front of the eyes to clearly see the surroundings.[0004]Another conventional welding helmet may have a function of automatically adjusting light transmittance. The welding helmet may automatically change light transmittance of a viewing lens. Ther...
