Following examples are implemented under premised on technical solution of the present invention, give detailed embodiment and tool The operating process of body, but protection scope of the present invention is not limited to following embodiments.In following embodiments, method therefor is such as no special Do not mentionlet alone and bright be conventional method.
[embodiment 1]
In the present embodiment, a kind of high-grade lcd welding goggles, from top to bottom include successively thickening optical filter, a c benefit Repay polaroid, a lcd liquid crystal cell, the 2nd c compensation polaroid, the 2nd lcd liquid crystal cell and r and compensate polaroid；Described first, The liquid crystals twist angle of two lcd liquid crystal cells is 70 °, and first, second c compensates in polaroid absorption axiss and first, second lcd liquid crystal cell The angle of friction mandrel is respectively 1 °；First, second c compensates polaroid and the singleton transmittance of r compensation polaroid is 42%, partially Luminosity is all 99%；Thickening optical filter is ultraviolet filter, and thickness is 1mm, singleton transmittance 27%.
Described first liquid crystal cell, the second liquid crystal cell are tn type liquid crystal cell.
Described first liquid crystal cell, the thickness of liquid crystal layer of the second liquid crystal cell are 3 μm, and the thickness of upper and lower glass substrate is 0.8mm, sheet resistance 35 ω/.
According to the computing formula of welding goggles color number, color number=(7/3) (1gl/t)+1, wherein t represents human eye and electric welding Transmitance between light source, can be by the transmitance digitized of protective eye lens by this formula.When human eye directly observes pad When, transmitance is 100%, color number=1；When having protective eye lens to block and protective eye lens are started working the most black state, transmitance reaches During to 0.00072%, color number=13.
Peak demand to welding goggles view angle dependency at present is:
1) in the range of colors No. 9～13, when visual angle deflects 15 °, 360 ° of scope color changes are less than a color number (bag Include increase or reduce)；
2) for colors No. 13, when visual angle deflects 15 °, color reduction in the range of 360 ° is less than 0.5 color number；
3) for colors No. 13, when visual angle deflects 30 °, color reduction in the range of 360 ° is less than 2.5 colors number；
Taking European Union's ce1/1/1/2 standard as a example, in the range of colors No. 9～13, when visual angle deflects 15 °, 360 ° of scope colors Number change is as shown in the table:
15 ° of visual angles:
As can be seen from the above table, in 15 ° of visual angle deflects, color change is more than 1 for the product of this rank；This expression makes User can experience the strong and weak change of light luminance when rotating eyeball, and colors No. particularly 13 have decrease beyond 0.5 color number, table Bright product visual angle is not wide.
Equally taking European Union's ce1/1/1/2 standard as a example, in the range of colors No. 9～13, when visual angle deflects 30 °, 360 ° of models Enclose color number change as shown in the table:
30 ° of visual angles:
As can be seen that colors No. 13 have decrease beyond 2.5 colors number, user can enter from more black state when rotating eyeball Enter relatively bright state, sensation can be very uncomfortable
The present embodiment properties of product test data is as follows:
Light valve on state of transmitance: (optical filter passes through unit: %)
Optical filter 27.0%
Ecs on state of (combines) 3.71
On state of color number 3.71, requires the color number of on state of more low better in principle, shows that the transmitance of protective eye lens is higher, vision More clear；And the voltage of the present embodiment product, power consumption are relatively low.
After tested, the homogeneity of the present embodiment product reaches European Union ce certification primary standard, as shown in the table:
Homogeneity is tested:
After tested, the light diffusivity of the present embodiment product reaches European Union ce certification primary standard, as shown in the table:
Light diffusion is tested:
After tested, under the present embodiment product different temperatures, the change of color number, response speed reach European Union ce certification one-level mark Standard, as shown in the table:
High/low temperature is tested:
After tested, the view angle dependency of the present embodiment product has similarly reached European Union ce certification primary standard, its visual angle Relatively wide, color excursion is relatively small, and experience is more comfortable.
Dependence of angle is tested:
15 ° of visual angles:
30 ° of visual angles:
Conclusion: according to the welding goggles product obtained by the present embodiment, the photoinduction system on its eyeglass can be in moment Detect the generation of arc light and disappearance during electric welding, rapid driving liquid crystal shading variable color, thus reach can block in welding Strong arc light, can recover rapidly the effect in the clear visual field again after welding stops, thus the eyes of effective protection welder, ensureing Being smoothed out of welding job.
The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, Any those familiar with the art the invention discloses technical scope in, technology according to the present invention scheme and its Inventive concept equivalent or change in addition, all should be included within the scope of the present invention.
