This utility model belongs to electrooptics glasses class, and particularly the protection eyes make it alleviate " the electronics protective eye lens of the quick variable color of day and night " that stimulated by high light and illuminance cataclysm in daily life.
A kind of known sensitization discoloration mirror, it is to add necessary composition in glass for lenses, makes its characteristic with sensitization discoloration, and its shortcoming is that variable color speed is slow, " in the optical technology handbook (China Machine Press) record data be that the sensitization discoloration mirror was water white transparency or light color originally, be subjected to light after 5 minutes, decay high light 50% is again through 60 minutes, decay 60%, remove high light after 5 minutes, return to decay and recover fully after 25%, 60 minute.The pace of change of the ambient light illumination that people faced is often in the time less than 1 second, illumination change 1-2 the order of magnitude, obviously, the variable color speed of sensitization discoloration mirror is too wide in the gap with the pace of change of ambient light illumination, according to another " the electrooptics handbook (compile by the Radio Corporation of America, the trivial school of translating of Shi Siwu), (Chinese National Defense Industry Press 1978 publish) institute remembers that human eye is from adaptation field luminance 3 * 10
-5The dark situation of nit changes the bright ring border that the adaptation field luminance is equal to or greater than 3 nits into, approximately needs 2-3 minute.By the data contrast as can be known, the too late human eye self of the variable color speed of sensitization discoloration mirror by the speed-adaptive that secretly brightens, can think that sensitization discoloration mirror variable color speed is its major defect slowly to environment.
The purpose of this utility model is to provide a kind of and can protects the sunlight of the place ahead along the incident cataclysm of pupil direction in the daytime, and make its optical attenuation scope adaptation function be arranged to the elevation angle of the sun, can protect night to the light of cataclysm, the enhanced strain of the illuminance time is equal to or less than the electronics protective eye lens of 0.1 second the quick variable color of day and night, (to call " this protective eye lens " in the following text).
The purpose of this utility model is achieved in that
The electronics protective eye lens of the quick variable color of a kind of day and night, include mirror holder, to row meander configuration liquid crystal lens, control box, be provided with power supply, electrical switch, pulse generator in the control box, electrical switch is connected across between the feeder ear of power supply and pulse generator, the signal output part of pulse generator be connected to row meander configuration liquid crystal lens; It is characterized in that: described power supply is made of silicon solar cell and chemical battery sets; This power supply is connected with described electrical switch through a photo-sensitive cell.
This utility model will produce following actively beneficial effect:
This utility model replaces the sensitization discoloration eyeglass with to row meander configuration liquid crystal lens (being called for short eyeglass sometimes), by electric impulse signal it is controlled, and realizes quick variable color.
The dead ahead illuminance is 5 * 10 when using in the daytime
3When LX is following, be 30% to row meander configuration liquid crystal lens vertical incidence light light transmittance, the dead ahead illuminance is 5 * 10
3LX-5 * 10
4The variation that grows from weak to strong of LX scope, then approximate drop to 12% to row meander configuration liquid crystal lens vertical incidence light light transmittance by linear relationship by 30%, this item number is according to showing the wearer, be equivalent to wear 1 pair of common sunglasses during low-light (level), be equivalent to wear 2 secondary common sunglassess during high illumination, the light transmittance of left and right sides and front lower place then remains at 42%.As previously mentioned, increase with the dead ahead illuminance, increase to row meander configuration liquid crystal lens applied field intensity, its elliptic cone solid angle axis that transillumination attenuation range is constituted reduces the inclination angle of eyeglass normal, if the sun is in the front upper place, elevation angle is 45 °, sunlight just can only the direct projection solaode sub-fraction, the dead ahead illuminance is just on the low side, just on the low side to row meander configuration liquid crystal lens applied field value, above-mentioned inclination angle is higher, for example 25 spend, the elevation angle of transillumination attenuation range is 2.5 degree-47.5 degree, the sun then is in the upper limb of attenuation range with the lining, if the elevation angle of the sun is at 30 degree, the sunlight direct projection increases at the area of silicon solar cell, but still not whole, institute's making alive on row meander configuration liquid crystal lens raises and does not arrive maximum as yet, reduce at above-mentioned inclination angle, be 20 degree, the elevation angle of transillumination attenuation range is extremely positive 42.5 degree of negative 2.5 degree, the sun then is in the Zhong Shang district of attenuation range, if the elevation angle of the sun is 0 degree, the whole silicon solar cell of sunlight direct projection, institute's making alive is near 2.2V on row meander configuration liquid crystal lens, and above-mentioned inclination angle is near 0 degree, the elevation angle of attenuation range is extremely positive 22.5 degree of negative 22.5 degree, and the sun is in the center of attenuation range.No matter how many elevation angles of the sun is, to the light transmittance at row meander configuration liquid crystal lens attenuation range center all at 10%-12%, the light transmittance of the left and right sides and front lower place all remains on about 42%, when the elevation angle of the sun is spent greater than 45, considerably beyond the scope of human eye pupil incident illumination, the necessity of protection is little.
Introduce the effect of using night below, human eye is higher 2.5 times than in the daytime to the light energy detectivity at night, differs 5 orders of magnitude in the daytime to the subject range of illuminance is same, in the daytime 10
4LX just calculates high illumination; And night several LX illuminance often make the people feel dazzling, the car bulb on the highway from far near, for example its illumination is from 8 * 10
-1LX reaches 8 * 10 in 1 second
0LX rises sharply 10 times, when using this utility model, when light is far away infrared receiving diode D2 internal resistance big, circuit is inoperative, light transmittance is 42%, transillumination illumination 3.66 * 10
-1Lx; When light is near, the circuit starting, light transmittance is 12%, transillumination illumination 9.6 * 10
-1Lx, from this example, under this utility model effect, 10 times the ambient light illumination of rising sharply passes to human eye, only raises 2.86 times.When setting starting illuminance was 5lx, the suffered illuminance prestart of eyes was 2.1lx.After starting, if making by the illuminance behind row meander configuration liquid crystal lens is 2.1lx, the illuminance that then enters before row meander configuration liquid crystal lens will be up to 17.5lx, this direct ratio bias light illumination 10
-1Lx exceeds two orders of magnitude, is to set 3.5 times that start thresholding (for example 5lx).
Of the present utility model is 100 milliseconds to row meander configuration liquid crystal lens with the time that illuminance changes response, so, with the sensitization discoloration mirror relatively, it is fast to have rate of straining, day and night, elevation angle to the sun when using in the daytime has adaptation function, and the object of observing in same visual field to left and right sides and front lower place when the high light of dead ahead light source is implemented high attenuation rate is implemented advantages such as underdamp rate.

To row meander configuration liquid crystal lens 1 and 2 pairs of elliptic cone solid angles that the transillumination attenuation range is constituted, there is an inclination angle to the eyeglass plane normal its axis along the minor axis direction, this also is early known for the maker of liquid crystal device and application person, confirming from different directions liquid crystal device to be observed has different-effect, and agreement is expressed its direction with the reading of clock face, claim viewing angle, viewing angle is not above-mentioned inclination angle, be to determine major diameter, minor axis is with the structural parameters of position relation around the eyeglass, not with electric field change, but never the someone payes attention to in the then corresponding rule that reduces in the above-mentioned inclination angle of enhancing of applied field on row meander configuration liquid crystal lens, more do not go to utilize this rule, this utility model is used this rule and is solved to row meander configuration liquid crystal lens 1 and the 2 pairs of transillumination attenuation ranges adapt to the azimuth of intense light sources and the measure of elevation angle is: get clock 6 points to row meander configuration liquid crystal lens 1 and 2 viewing angles, the elliptic cone solid angle major diameter that its transillumination attenuation range is constituted is in horizontal direction, because its corresponding drift angle is 3-9 times of pupil visual field solid angle, direction is stable again, needn't worry too much, the elliptic cone solid angle minor axis that its transillumination attenuation range is constituted is in vertical direction, as long as it is in the time of making the elevation angle of the sun big, low to row meander configuration liquid crystal lens 1 and 2 applied fields; Sun altitude is hour to row meander configuration liquid crystal lens applied field height, and the axis of the elliptic cone solid angle that its transillumination attenuation range constituted is coincide with inclination angle between the eyeglass normal and sun altitude.About 10 ° get final product said inclination angle in the face of the high light of the glancing incidence of dead ahead night, how in various application scenarios to adding that to row meander configuration liquid crystal lens the electric field that suits has just become key.
Driving is not permanent electric field to the electric field of row meander configuration liquid crystal lens 1 and 2 variable colors, and need polarity not stop the alternating electric field of conversion, the method that this utility model obtains alternating electric field is that a dc source is set, produce the bidirectional pulse of certain frequency again by pulse generator IC1, the height that for a change needs the modulating pulse amplitude to the size of row meander configuration liquid crystal lens applied field, as long as to modulating for the voltage magnitude of pulse generator IC1 power supply, on row meander configuration liquid crystal lens 1 and 2 in addition the voltage magnitude of pulse signal also just be subjected to modulation, its actual required amplitude range is 1.5V-2.2V.This utility model has adopted different modes that the amplitude of supply voltage is modulated to using with night in the daytime.
When using in the daytime, provide 3V DC voltage string to make voltage decline 0.45V with chemical battery sets E2 with forward diode D1, it is 2.55V that chemical battery sets E2 gives the voltage of pulse generator IC1 real, silicon solar cell E1 parallel connection load resistance R1, be connected in series to chemical battery sets E2 and diode D1 again, the ambient light illumination variable quantity is converted into photovoltage, its numerical value is at 0-0.5V, is superimposed upon on above-mentioned 2.55 the voltage, synthesizes supply voltage, its numerical value is 2.55V-3.05V, its variation is with ambient light illumination value correspondence, and the ambient light illumination value is low, and the supply voltage amplitude is also low in the daytime, ambient light illumination value height, the supply voltage amplitude is also just high in the daytime.
When but the sun is in different elevation angles, the photovoltage that silicon solar cell E1 is produced does not have significant difference, so can not make to make and give phase reaction to row meander configuration liquid crystal lens 1 and 2, in order to address this problem, the measure that this utility model is taked is that the sensitive surface of silicon solar cell E1 is installed forward, and add an annular light shield 4 around it to open front, annular light shield 4 has certain degree of depth, when the elevation angle of the place ahead sun is big, sunlight can not direct projection silicon solar cell E1, photovoltage must be low, also low to row meander configuration liquid crystal lens to the attenuation rate of vertical transillumination, the axis of the elliptic cone solid angle that its attenuation range constitutes is just big to the inclination angle of eyeglass plane normal, just in time adapt to the sun of elevation angle when big, when the elevation angle of the place ahead sun hour, sunlight can direct projection silicon solar cell E1, photovoltage is inevitable high, attenuation rate to row meander configuration liquid crystal lens 1 and 2 pairs of transilluminations is just high, the elliptic cone solid angle axis that its attenuation range constitutes is just little to the inclination angle of eyeglass normal, the sun that just in time adapts to elevation angle hour, because annular light shield 4 has been arranged, sun altitude hour, if be in side direction sunlight can not direct projection to silicon solar cell E1, so photovoltage is lower, attenuation rate to row meander configuration liquid crystal lens 1 and 2 pairs of vertical transilluminations is also just lower, and this has just possessed direction identification and adaptive functions to the glancing incidence high light simultaneously.
When using night, still provide 3V DC voltage with foregoing chemical battery sets E2, give aforesaid pulse generator IC1 power supply by a negative-positive-negative transistor VT, the emitter stage of audion VT connects the negative pole of chemical battery sets E2, the electronegative potential feeder ear that the colelctor electrode of audion VT meets pulse generator IC1 is the 7th foot, the high potential feeder ear of pulse generator IC1 is the 14th foot meets chemical battery sets E2 by resistance R 1 a positive pole, the base stage of VT is received the positive pole of chemical battery sets E2 by an infrared receiving diode D2 who does photo-sensitive cell, the base stage of audion VT is received the negative pole of chemical battery sets E2 again by a photoelectric current sample resistance R2, the infrared receiving diode D2 current sampling resistor R2 that shares the same light becomes series system, this has just constituted the power supply circuits at night, the modulation that voltage magnitude is changed by ambient light illumination.In order to get rid of the interference of side direction high light, around infrared receiving diode D2, annular light shield 4 is housed also, work process is as follows: when the low light level, ambient light illumination is 10
-2-10
-1LX, the resistance approach infinity of infrared receiving diode D2, electric current is very little on it, electric current on the photoelectric current sample resistance R2 is also very little, this ohmically voltage is lower than 0.4 volt, and the outfan resistance of audion VT is very big, and output current is approximately zero, dog days' voltage of chemical battery sets E2 is almost high-fall between the emitter and collector of audion VT, makes voltage on the pulse generator IC1 be approximately zero thereby do not start; When the ambient light illumination grow, the resistance of infrared reception two pipe D2 descends, photoelectric current increases, electric current on the photoelectric current sample resistance R2 increases simultaneously, voltage on it also increases, when voltage is 0.4-0.67V thereon, audion VT outfan resistance descends, this time-division of 3V voltage that chemical battery sets E2 provides is added between the outfan and pulse generator IC1 of audion VT, its intrinsic standoff ratio is determined by ambient light illumination, be exactly in other words on the pulse generator IC1 institute's making alive amplitude modulate by the variation of ambient light illumination, vertical transillumination attenuation rate to row meander configuration liquid crystal lens in this illuminance scope increases rapidly with the illuminance increase, when ambient light illumination reaches when for example setting value 5LX, pressure drop on the photoelectric current sample resistance R2 reaches 0.67V, conducting resistance when audion VT outfan resistance hangs down to the switch utilization, voltage drop has only tens millivolts on it, the 3V voltage that chemical battery sets E2 provides almost has been added on the pulse generator IC1 entirely, reaches the maximum that uses night to row meander configuration liquid crystal lens 1 vertical transillumination attenuation rate with 2.More as can be known, the processing that is subjected to synthetic supply voltage amplitude that is added on the pulse generator IC1 is linear relationship in the daytime with ambient light illumination, and become thresholding to be setting value (for example 5LX) rising edge form of light-triggered switch slowly at night, this is poor for adapting to the night illumination condition, when dead ahead does not have high light, make full use of original illuminance, reduce the consideration of artificial loss.Because the switching device of pulse generator IC1 outfan has the pressure drop about 0.8V, in the daytime the power supply amplitude of 2.55-3.05V is behind process pulse generator IC1, the pulse amplitude of output has just dropped to 1.75V-2.25V, night 3V the power supply amplitude through behind the pulse generator IC1, the output maximum amplitude then is 2,2V, be added in pulse voltage amplitude on row meander configuration liquid crystal lens 1 and 2 a little less than 2.2V in order to ensure day and night, also in order to adapt to cmos circuit and to the dispersion of row meander configuration liquid crystal lens 1 and 2 parameters, outfan at pulse generator IC1 is used for the divider resistance R4 that resistance is adjusted by two respectively, R5, be connected with 2 to row meander configuration liquid crystal lens 1 with two again, if the pressure drop on the divider resistance is quota 0.1V, the voltage that then is added in the daytime on row meander configuration liquid crystal lens 1 and 2 is 1.65-2.15V, the voltage that adds night thereon is 2.1V, just belonging to row meander configuration liquid crystal lens 1 and 2 scopes that require, in order to be convenient to operate respectively with night in the daytime after combining, so added battery main switch K1, used in the daytime and use K switch 2 at K switch 3 and night.
Introduce the operational approach of " this protective eye lens " below and wear sensation.
In order to prevent to misread, also to clarify a notion.The promptly so-called elliptic cone solid angle that constitutes to row meander configuration liquid crystal lens transillumination attenuation range, it can not find on eyeglass, it is when measuring light transmittance anisotropy index, setting is 100% with the relative attenuation rate at decay center, decentre attenuation rate far away more is low more, is that the edge that has reached decay is then thought at central value 1/3 place to attenuation rate, attenuation rate scope and the elliptic cone solid angle thereof of delimiting as boundary, in fact still having underdamp, attenuation rate beyond the attenuation range is gradual change.No matter this gradual change shows or shows in the time mode in spatial mode, can feel nature concerning user.Take and see that to row meander configuration liquid crystal lens 1 and 2 are navy blues, be worn on and see it is sky blue at the moment.
On daytime, at the bright weather of eyeball, early morning is in the face of the Chaoyang of initial rise or at dusk in the face of the setting sun of west before down, high light can be come in flat fire, and is very dazzling, and wear this protective eye lens and can obtain good effect this moment.Operational approach is that K1 places on-position battery main switch, using night K switch 2 to place off-position, uses K switch 3 to place on-position in the daytime.This protective eye lens is worn as common spectacles, look around 360 degree, the wearer will have following sensation: the sun or side direction solar time dorsad, see through this protective eye lens and watch environment, the sensation sky is more blue, other scenery show slightly Sandy, over against the solar time, the incident sunlight of horizontal direction is as being subjected to the sky blue tulle of one deck dazzling consumingly blocking no longer, and the scenery of both sides and front lower place is still clear simultaneously, not only can see the number plate of the motor vehicles that is travelling clearly, also can see the spoke of the bicycle of parking clearly, to the solar time, feel that then oblique upper is sky blue, dead ahead tiltedly, front lower place and side, the left and right sides still are shallow dark brown.Wear this protective eye lens and from the erect-position side sun is turned to rapidly over against the sun, compare with naked looking, eyes institute irriate is light, the traffic policeman that many people are for example on duty, and frequent conversion is inevitable to such erect-position.High noon, blazing sun on the crown is not directly radiance directive pupil, wear this protective eye lens back to sun place direction, sensation and early morning, at dusk identical, and during in the face of sun place direction, but be in dead ahead, but be in the front upper place unlike early morning with at dusk as the barrier bed of sky blue tulle, just in time penetrate the direction of coming and conform to, make it to avoid dazzling with daylight.To watching then because of the interference of having got rid of the oblique upper solar glare has increased convenience of dead ahead, front lower place, side, left and right sides scenery, optical attenuation scope that Here it is has the embodiment of adaptation function to sun altitude.
On the highway at night, the illuminance that bias light causes only is 10
-2～10
-1Lx.And the automobile in advancing 5～10 meters apart from the time, the illumination that its light caused then reaches 10
0～10
1Lx.Work at night personnel traffic policeman for example on duty on highway, the strong variations of the ambient light illumination of being faced is can the major injury vision.Wear this protective eye lens and also can achieve good results this moment.Operational approach is that battery main switch K1 is placed on-position, using night K switch 2 to place on-position, using K switch 3 to place off-position in the daytime, this protective eye lens is worn as common spectacles.The wearer will have following sensation: the bias light that does not have strong variations in the face of illumination, light as the night sky of dark, sky, crossing or the end of the bridge that a bright moon hung in the sky, just as wearing a secondary common dark brown sunglasses, the automobile approaching that big light opening is arranged when the place ahead, darkening of beginning eyeglass top, then dark color moves down, until the light effective attenuation of coming is put down in the place ahead, simultaneously, can observe as usual road surface, left and right sides environment and differentiate in two-way the advancing various vehicles.
When inactive and to chemical battery sets E2, charging, place off-position to battery main switch K1.
