Description
One, technical field
The utility model relates to protective glasses, particularly a kind of safety goggles that can prevent the strong illumination human eye by automatic color-changing.
Two, background technology
The irradiation of people's eyes tolerance high light is limited, and light is too strong, and gently then producing stimulates and dizzy sensation, and is heavy then eyes are caused damage.For this reason, people have invented the lower sunglasses of transmittance very early, are used for the stimulation of anti glare anti static coatings to eye.But the transmittance of sunglasses is fixed, and can not change with the variation of extraneous light, therefore is not suitable for using under general visible rays.So, invent a kind of light-sensitive sunglasses that can change transmittance automatically and necessitate along with the power of extraneous light.
Notification number is that the Chinese patent of CN2032333U once disclosed a kind of glasses with an automatic light meter, the eyeglass of these glasses adopts liquid-crystalline glasses to constitute, liquid crystal lens is by the liquid-crystal controller control that is installed on the mirror holder, provide working power by the solar cell that places the cartridge battery in the human body coat pocket or be installed in mirror holder the place ahead for liquid-crystal controller, photoresistance by bias light control is installed, anterior photoresistance of installing by (facing to human eye) irradiates light control on the top of mirror holder.The oscillator that liquid-crystal controller is made of the double operational circuit produces square wave control voltage, and this voltage carries out dividing potential drop by the light adjusting circuit that is made of elements such as photoresistance and adds to liquid crystal lens.Its light modulation principle is: the resistance that is installed in the photoresistance of mirror holder top and front portion changes along with the Strength Changes of bias light and irradiates light respectively, when the irradiation light intensity is identical with bias light, the voltage that is added in after the dividing potential drop on the liquid crystal lens is very low, liquid crystal lens is well-illuminated state, when the irradiation light intensity is higher than bias light, the voltage that is added on the liquid crystal lens raises, the liquid crystal lens transmittance reduces, beginning is by bright deepening, the intensity contrast of irradiates light and bias light is big more, the voltage that is added on the liquid crystal lens is high more, and liquid crystal lens is dark more.
There are three shortcomings in above-mentioned glasses with an automatic light meter.First shortcoming is; because the transmittance of liquid crystal lens is controlled by the intensity contrast of irradiates light and bias light; therefore; this glasses only suit to use under night or dark working environment; this moment, bias light was dark, as long as irradiates light appears in the place ahead, will form bigger contrast with bias light; the liquid crystal lens deepening, thus human eye is played a protective role.And by day, especially under stronger daylight, or on the snowfield of Da Mianji, and under the working environment (by the converter that flashes as molten steel) that bias light is stronger around some, the background light intensity is enough to make human eye to feel to stimulate, as this moment irradiates light be exactly bias light (being that the place ahead does not have other light to occur), or irradiates light intensity to surpass bias light little, liquid crystal lens just can variable color or variable color very little, wear this glasses this moment and just do not reach protective action eyes.So this glasses are not suitable for using under the stronger situation of bias light, its usable range is limited.Second shortcoming is, the liquid-crystal controller of these glasses has determined its operating voltage and electric current higher by its circuit structure, voltage can not be lower than 6V, otherwise do not reach the branch pressure request, electric current is also in the mA level, in addition in the glasses use, the output voltage of liquid-crystal controller and electric current are in running order all the time, therefore Overall Power Consumption is big, no matter be to adopt solar cell or self-contained battery to make power supply, all enough capacity must be arranged, this can not do very for a short time with regard to the area (with regard to solar cell) or the volume (to self-contained battery) that make power supply.Yet, glasses itself be one occupy the space very limited than small articles, the area or the volume of power supply are big, just be difficult to be made of one with glasses, and beyond glasses in addition attached power supply (in the human body coat pocket, placing power supply exactly) as this Light-modulating mirror certainly will cause the inconvenience of use.The 3rd shortcoming is that this glasses liquid crystal its transparency under certain irradiates light intensity is non-adjustable, can not satisfy the different requirements of different people to penetrability.
Just because of there are above-mentioned three shortcomings in these glasses, cause this patent not seen and implement to form product.
Three, utility model content
The purpose of this utility model is improved at the shortcoming of above-mentioned light modulation glasses, and a kind of automatic color-changing mirror of anti glare anti static coatings irradiation is provided.This light-sensitive glasses usable range is wide, power consumption is little, power supply and glasses can be made of one, and its transparency is adjustable under certain irradiates light intensity, and eyeglass can not cause flickering to the people when fluctuating up and down in the critical value of variable color (be liquid crystal lens by bright beginning deepening time irradiates light intensity) when irradiates light intensity.
The automatic color-changing mirror of the anti glare anti static coatings irradiation that the utility model provides, a kind of automatic color-changing mirror of anti glare anti static coatings irradiation, comprise mirror holder, liquid crystal lens, power supply and the liquid-crystal controller that is installed on the mirror holder, be characterized in that said liquid-crystal controller comprises light-operated circuit and oscillator and the driving circuit controlled by this light-operated circuit; Wherein light-operated circuit by the phototriode BG1 that is installed in the mirror holder front portion, form the triode BG2 of complex pipe with phototriode BG1 and constitute with resistance R 3 that the BG2 emitter joins; Oscillator is by time base circuit IC1 and join with 2,6 pin of the pin 8 of IC1, pin 1, pin 7, short circuit and the external circuit that is made of resistance R 1, R2, triode BG3, diode D and capacitor C 1 constitutes, and the 4 foot control system terminal voltages of IC1 are provided by the emitter of BG2; Driving circuit is made of two-way inverter ic 2a and the IC2b that the pin 3 of input end and IC1 joins; The operating voltage of two-way phase inverter is provided by adjustable resistance R4 by the emitter of BG2, and adjustable resistance R4 regulates with the knob that is installed on the mirror holder.Said power supply is the solar cell that is installed in the button cell of mirror holder sidepiece or is installed in the mirror holder front portion.
The advantage of the utility model automatic color-changing mirror can obtain explanation by its following principle of work.When the place ahead does not have irradiate light or irradiates light intensity low, the photocurrent that phototriode BG1 does not produce photocurrent or generation is very little, not conducting of triode BG2, the BG2 emitter voltage is near 0 volt, oscillator does not require nonoscillatory because of control end voltage reaches, no-voltage output, the liquid crystal lens no-voltage drives, and keeps pellucidity; As irradiate light, and when reaching certain intensity, the photocurrent that phototriode BG1 produces makes the BG2 conducting, irradiates light is strong more, photocurrent is big more, its emitter current is big more after BG2 amplifies, the BG2 emitter voltage is high more, when this voltage reaches the control voltage (being set at 0.7V as the utility model) of oscillator requirement, oscillator is started working, the square-wave pulse signal that IC1 output frequency and voltage amplitude are constant, and this signal is through the two-way inverter drive, the square-wave voltage that forms positive and negative stack drives liquid crystal lens, makes it by transparent deepening.Because irradiates light intensity is being controlled the operating voltage of two phase inverters simultaneously by triode BG2, so irradiates light is strong more, the driving voltage that phase inverter is exported is high more, and the transmittance of liquid crystal lens is then low more, and appearance color is dark more.Although the square-wave pulse signal voltage constant of IC1 output does not change with the irradiates light Strength Changes, the transmittance of liquid crystal lens, that is the variable color amplitude is but along with the linear change that is varied to of irradiates light intensity.That is to say that liquid crystal lens can from the superficial to the deep be the state of gradually changing along with irradiates light intensity its color of changing from small to big, in case rather than simple irradiates light intensity surpass critical value and just become unalterable deep dark suddenly.Like this, no matter how irradiates light intensity changes, the luminous flux total energy that enters the human eye pupil keeps constant substantially, and this just makes these glasses both can use at night or dark place, also can use down by day or than high light wire loop border.When the ambient light line strength surpasses the critical value of variable color but is not very strong (as under common daylight), liquid crystal lens can be because of the very dark vision that influences that becomes, so the usable range of this light-sensitive glasses is very wide.Simultaneously, when irradiates light intensity when the critical value of variable color fluctuates up and down, liquid crystal lens also just changes under more shallow color, can not cause the discomfort sensation of frequent flicker to human eye.
Under certain irradiates light intensity, different users is as needing to regulate among a small circle the variable color degree of depth of liquid crystal lens according to the personal preference, can realize by operating voltage and even its outputting drive voltage that knob is regulated the resistance of resistance R 4 and then regulated phase inverter.
When the liquid-crystal controller of the utility model light-sensitive glasses does not reach the critical value of variable color in irradiates light intensity, that is to say when liquid crystal lens variable color does not take place, is idle, essentially no power consumption; Because of driving voltage all is added on the liquid crystal lens, rather than employing dividing potential drop form, so IC1 can adopt the integrated circuit of low voltage operating, working current is less in addition, make the utility model light-sensitive glasses power consumption very low, for the solar cell of small-sized button cell or small size is installed,, power supply and glasses become possibility thereby being made of one on mirror holder.
