Description

Automatic light-blocking laser light filter and welding helmet The present disclosure generally relates to welding helmets, and more specifically to an automatic light-blocking laser filter for welding helmets. In welding operations, workers wear a welding helmet or hood on their heads to prevent injury from various harmful rays caused by the welding arc ignition and any substances produced by the welding process. Some welding helmets are equipped with an automatic light-blocking filter consisting of a liquid crystal display, control circuitry, solar panels or batteries, light-sensitive sensors, and a light filter. The light filter prevents harmful ultraviolet and infrared rays emitted by welding equipment from reaching the welder's eyes and causing harm, while allowing sufficient light for the welder to safely see their work. However, conventional welding helmets and automatic light-blocking filters are designed solely to protect against harmful light emitted by conventional welding methods. The present disclosure relates to an automatic light-blocking laser light filter for welding and a welding helmet comprising the same. In one embodiment, a welding helmet is provided. The welding helmet comprises a metal mask having an opening and an auto-shielding laser filter positioned behind the opening. The auto-shielding laser filter comprises a metal panel having an opening, an auto-shielding filter positioned behind the opening, and a laser lens configured to filter a range of wavelengths of light. The metal panel is positioned on the outer surface of the auto-shielding laser filter and is adjacent to the metal mask. The laser lens is positioned on the auto-shielding filter. In another embodiment, a device for filtering light is provided. The device includes a metal panel having an aperture, an auto-shielding filter configured to selectively filter light, and a laser lens configured to filter a range of wavelengths of light. The metal panel is located on the outer surface of the device. The auto-shielding filter is located behind the aperture. The laser lens is located on the auto-shielding filter. Other technical features may be readily apparent to those skilled in the art from the following drawings, description, and claims. Before beginning the detailed description of the invention below, it may be advantageous to provide definitions of specific words and phrases used throughout this patent document. The term “couple” and its derivatives refer to any direct or indirect communication or connection between two or more components, regardless of whether these elements are in a state of physical contact with each other. The terms “include” and “constitute” and their derivatives mean inclusion without limitation. As used herein, the terms “outer direction,” “outer side,” “front side,” or “front side” refer to an outward-facing face or side that is away from the worker’s face when the welding helmet is worn on his/her head; and the terms “inner side,” “rear side,” or “rear side” refer to an inward-facing face or side that is facing the worker’s face when the welding helmet is worn on his/her head. The term "or" is inclusive and means "and/or." The phrases "related to" and their derivatives mean including, being included within, being interconnected, including, being included within, being connected to or connected to, being combined with or combined to, being communicable with, cooperating with, interleaving, juxtaposing, being close to, being combined with or combined to, having, possessing the characteristics of, having a relationship with or related to, etc. The term "controller" means any device, system, or part thereof that controls at least one operation. Such a controller may be implemented in hardware or a combination of hardware and software and/or firmware. As used herein, when referring to a range or number, "about" means within at least 10%, and any disclosed range includes the beginning and end of the range unless otherwise specified (e.g., a range of 1 to 10 includes 1 and 10). When used with a list of items, the phrase "at least one" means that one or more different combinations of the listed items may be used, and that only one item may be required from the list. As an example, "at least one of A, B, and C" includes any of the following combinations: A, B, C, A and B, A and C, B and C, and A, B, and C. Definitions for other specific words and phrases are provided throughout this patent document. Those skilled in the art should understand that, in many, if not most, cases, these definitions apply to the prior and future use of these defined words and phrases. For a more complete understanding of the present disclosure and its advantages, refer now to the following description taken in combination with the accompanying drawings, wherein the same reference numerals denote the same components.
