Abstract
The utility model relates to protection glasses preventing strong light irradiation, ultraviolet rays and eye fatigue provided for automobile and motorcycle drivers, oxygen welding cutting people and field operation people. The utility model comprises a glass frame 6 and a lens 5 and is characterized in that the lens 5 is a liquid crystal lens and the glass frame 6 is provided with the driving circuit 3 of the liquid crystal lens. The utility model has rapid color change, strong light shading performance and obvious distinction for light strength.
Description
The utility model is for a kind of anti-high light thorn that automobile, Motor-cyclist, oxygen welding cutting personnel, field work personnel provide is penetrated, the protection instrument of uvioresistant, anti-eye fatigue.
Light-sensitive glasses in the market, sunglasses, the anti-light microscopic of dazzling all is the color method that adds that adopts plated film or eyeglass.Its shortcoming is: sunglasses use better by day, and have a strong impact on eyesight night under the low light level; Light-sensitive glasses, the anti-light microscopic variable color speed slow (time was greater than 1 minute) of dazzling can not work when strong illumination at once, have little significance in actual applications, and it is not strong that high light anti-dazzled effect; Still can dim eyesight when the strong illumination of opposite.All these products can not reach obvious differentiation effect to strong and weak light.
The purpose of this utility model is to provide a kind of variable color agility, shading performance strong, and the power of light is distinguished significantly highly sensitive anti-high light security personnel glasses.
The utility model is achieved in that a kind of highly sensitive anti-high light security personnel glasses, comprises mirror holder and eyeglass, is characterized in that eyeglass is a liquid crystal lens, and device has the liquid crystal lens driving circuit on the mirror holder.
This product is changed the popular film plating process that anti-light microscopic, light-sensitive glasses adopted at present, and only adopts electrooptical liquid crystal sheet device principle, and photosensitive received signal, drives liquid crystal display are applied on the glasses.It is compared with in the market anti-light microscopic, light-sensitive glasses, and advantage is: variable color agility (time was less than 1/50 second), the shading performance is strong, and the power of light is distinguished obviously.Comprise street lamp, block neon light at the low light level, decorate under the floodlight that the nondiscolouring of this product minute surface is close to goggles, it is bright to look thing, and under high light (containing daytime), it is as sunglasses.Because there is polaroid on the LCD panel top layer of these glasses, under strong and weak light, all play and prevent dazzling light, antiultraviolet effect, it is particularly comfortable to wear the back eyes, plays good anti-fatigue effect.Simultaneously, it does not resemble in the market anti-ly dazzles light microscopic to wear the back people's that gives the sort of Huang daytime drizzly, the sensation that it is dark mixedly, and give clearheaded, refreshed sensation.Another advantage of these glasses is that photosensitive reception has directivity, and the people can select whether conversion of minute surface at random, to ensure sight line.
Fig. 1 is a general structure synoptic diagram of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Below in conjunction with accompanying drawing structure of the present utility model, principle being done one describes in detail:
As shown in Figure 1, the utility model is made up of mirror holder 6 and liquid crystal lens 5, and device has liquid crystal lens driving circuit 3 on the mirror holder 6.
As shown in Figure 2, liquid crystal lens driving circuit 3 comprises: contain the integrated circuit of four integrated unit A, B, C, D, three resistance R 1, R2, R3, three capacitor C 1, C2, C3, power supply 1 and photodiode V1.The bind mode of driving circuit is: capacitor C 1 two ends link to each other with power supply 1 positive and negative electrode respectively, photodiode V1 negative electrode links to each other with the end of resistance R 1, R2, the sun level links to each other with power cathode, resistance R 1 other end and 1 anodal linking to each other of power supply, resistance R 2 other ends and integrated unit A input end are 1., 2. pin links to each other, capacitor C 3 one termination powers 1 negative pole, the other end and integrated unit B input end 4. 5. pin link to each other and link to each other with resistance R 3 one ends; A integrated unit output terminal 3. with integrated unit D input end pin and integrated unit C input end 9. pin link to each other, B integrated unit output terminal 6. link to each other with resistance R 3 other ends and with integrated unit C input end 10. pin link to each other, 8. integrated unit C output terminal links to each other with integrated unit D input end pin and links to each other with liquid crystal lens 5 one pin , and integrated unit D output terminal links to each other with liquid crystal lens 5 another pin .Closure when liquid crystal lens 5 is high level is opened during low level.Power supply 1 is 2 joint 3V button cells, also can be external hole, external direct current power supply.Switch 2 also is housed on the mirror holder 6.The parameter of liquid crystal lens 5 is: the liquid crystal diopter: 6 o'clock; Polarization: transmitable; Multilayer horizontal line---static state; Color: dark brown.
