brief description of the drawings:
Further illustrate the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the structured flowchart of goggles set of the present invention.
detailed description of the invention:
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, goggles set structure in Auto-changing Shade Welding Mask Made of the present invention, its structure comprises that outer screening glass 101, optical filter 102, liquid crystal display screen sheet 103(also claim liquid crystal light valve sheet) and interior screening glass 104; Between described outer screening glass 101 and interior screening glass 104, be equipped with an optical filter 102 and two liquid crystal display screen sheets 103.
It is to be noted, because single chip liquid crystal screen sheet can not be obtained higher color number in the course of the work, can not stop strong arclight, it is more that light sees through liquid crystal display screen sheet, cause brightness still very high, common people's naked eyes are difficult to accept, therefore this patent adopts two liquid crystal display screen sheets can stop that more light sees through, brightness can be reduced to the degree that human eye is comfortable here.
In addition, two liquid crystal display screen sheets that adopt here all connect eyeglass control circuit, realize bright state in 0.1 millisecond and change to dark state, and can also realize in 0.1 millisecond to 1 millisecond and changing to bright state from dark state by reception control circuit signal.Specific explanations is as follows:
First, liquid crystal is the state of matter that has liquid and crystal two specific characters in certain temperature range concurrently, there is the organic compound of systematicness molecules align, conventional liquid crystal is nematic liquid crystal, and molecular shape is elongated clavate, and length is 1～10nm approximately, under the different functions of current, liquid crystal molecule can do rules rotating 90 degree and arrange, and produces the difference of permeability, thereby the difference that produces light and shade in the time of power connection and disconnection.
In the time that light receiving tube is accepted arc optical signal and become dark state to mirror group, needed interval, is referred to as response time.Can the time that the strong visible ray moment that it is subject to while being related to welder's striking irradiates, be also related to welding worker and clearly observe all the time in welding process, eliminate up hill and dale and blindly draw weldering and injury eyes.Response time is shorter, illustrates that the mirror group structural behaviour of electric welder's helmet is better.The response time of mirror group is mainly made up of response speed two parts of accepting arc light in the response time of liquid crystal material and circuit, but the response time of liquid crystal light valve sheet plays a major role, the conversion time that is liquid crystal display screen sheet is less, and the response time of mirror group also will shorten greatly.
The response time of liquid crystal display screen sheet and the voltage swing proportional (in certain scope) that is added in its two end, voltage is higher, and response time is just shorter.Apply output high direct voltage proportional to dutycycle when the liquid crystal display screen two ends moment in goggles set, under the condition of room temperature, in the time of DIN13, its response time can reach 0.1ms.
Secondly, optical filter adopts the bandpass filter of vacuum coating technology.Optical filter spectral characteristic main peak is between 520nm to 580nm, and peak transmission is greater than 50%.
As shown in table 1, this table is the labour protection articles for use quality monitoring testing station report of concluding according to relevant criterion, and harmful light penetrations such as infrared ray, far ultraviolet rays, nearultraviolet rays, blue light are being recorded in the inside.
