Problems solved by technology

At present, the welding goggles on the market can basically block all ultraviolet rays, and the infrared transmittance is less than 5%, but at the same time, the visible light transmittance is about 0.1%, so the vision is dark after wearing, which brings extreme difficulties to the welding workers. Big trouble, and directly affect the welding quality
[0003] In addition, the current welding goggles can not all reach the first level of CE certification in the four aspects of uniformity, light diffusion, response speed, and viewing angle dependence (including two indicators of 15° viewing angle and 30° viewing angle). Standard, the main problem of which is viewing angle dependence, which is usually 1 / 1 / 1 / 2 and 1 / 1 / 1 / 3 products

Embodiment 1

[0022] In this embodiment, a high-grade LCD welding goggle includes a thickened filter, a first C compensation polarizer, a first LCD liquid crystal cell, a second C compensation polarizer, and a second LCD liquid crystal from top to bottom. box and R compensation polarizer; the liquid crystal twist angle of the first and second LCD liquid crystal boxes is 70°, and the clamp between the absorption axis of the first and second C compensation polarizer and the internal friction axis of the first and second LCD liquid crystal boxes The angles are 1° respectively; the single transmittance of the first and second C compensation polarizers and R compensation polarizers are both 42%, and the degree of polarization is 99%; the thickened filter is an ultraviolet filter, the thickness It is 1mm, and the single transmittance is 27%.

[0023] Both the first liquid crystal cell and the second liquid crystal cell are TN type liquid crystal cells.

[0024] The thickness of the liquid crysta...

Abstract

The invention relates to a pair of high-class LCD welding goggles. The pair of high-class LCD welding goggles sequentially comprises a thickened light filter, a first C compensating polaroid, a first LCD liquid crystal box, a second C compensating polaroid, a second LCD liquid crystal box and an R compensating polaroid from top to bottom. The uniformity, light dispersivity, response speed and viewing angle dependence meet the primary standard of European union (CE) certification. When the pair of high-class LCD welding goggles is used, strong arc light can be blocked in time during welding, the state of clear viewing field can be also rapidly recovered after welding is stopped, and smooth performing of welding work is effectively guaranteed.

Description

technical field [0001] The invention relates to an LCD goggle, in particular to a high-grade LCD welding goggle whose uniformity, light diffusion, response speed, and viewing angle dependence meet the EU CE 1 / 1 / 1 / 1 standard. Background technique [0002] The short-term exposure of the ultraviolet rays generated by electric welding to the eyeball will cause damage to the cornea and conjunctival tissue (28nm light is the most serious), and the strong infrared rays generated can easily cause eye lens turbidity. Welding goggles are used to block infrared and ultraviolet rays. At present, the welding goggles on the market can basically block all ultraviolet rays, and the infrared transmittance is less than 5%, but at the same time, the visible light transmittance is about 0.1%, so the vision is dark after wearing, which brings extreme difficulties to the welding workers. It is a big trouble and directly affects the welding quality. [0003] In addition, the current welding gogg...
