Description
Technical field
The utility model relates to a kind of sunglasses, and body relates to a kind of liquid crystal sunglasses that can block high light automatically.
Background technology.
The light transmission rate of liquid crystal is relevant with the voltage that adds thereon, it has following photoelectric characteristic: when voltage is lower than the lower limit critical value, its light transmission rate changes slowly, insensitive, when control voltage is higher than the lower limit critical value and is lower than upper limit critical value again, the even transmittance of liquid crystal can reduce along with the rising of voltage sensitively, form the responsive control zone of even transmittance, after voltage is higher than upper limit critical voltage, light transmission rate has promptly no longer changed with the rising of voltage, so people are when using the transmittance of Control of Voltage liquid crystal sunglasses, the variation range of its control voltage all is selected on the responsive control zone, between the lower critical value, by changing the transmittance that magnitude of voltage in this scope changes liquid crystal lens.When outside average light photograph is strong, generally can be by strengthening the transmittance that control voltage reduces liquid crystal glasses, but for the such intense light source of the sun, if the transmittance of whole eyeglass is all reduced, promptly can when blocking the sun, also block its zone, such as causing the road in advancing also not see, so the liquid crystal sunglasses that has adopts the regional area to liquid crystal glasses to strengthen control voltage, only make this regional area deepening, other zone keeps enough transmittances, obtains the effect of " only hide the sun and do not hide the road ".But the intense light source in the human eye visual field is dynamic change, need the position of shading also to need continuous variation on the eyeglass, this has brought difficulty just for the control variable color, and the grid stick of some liquid crystal glasses by bidimensional control arranged, and dynamically blocks the incident light in some zones.The control mode complexity of these class glasses, need by more greatly, heavier, expensive electronic-controlled installation realizes its function, because practicality is relatively poor, so far do not see its commercialization, and the method for this class subregion control all will be divided into a plurality of zones to liquid crystal lens, could realize the control to the part, occurs the light and shade subregion on eyeglass, these glasses need keep a fixing distance between human eye and eyeglass, thereby calculate the angle of incident high light.This just will certainly make control circuit complicated, has increased the volume of control system, makes and use all inconveniences.
Summary of the invention
The technical problems to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of liquid crystal light and shade automatic shading sunglasses, this sunglasses will not be divided into a plurality of zones by liquid crystal lens, only the dynamic control that can be in the light according to the realization part, orientation of intense light source automatically on the eyeglass of a slice conducting film electrode is all arranged on the two sides, and have simple in structure, the characteristics that volume is little.
The technical scheme that addresses the above problem is: the utility model is provided with spectacle frame, and be contained in liquid crystal lens, controller and battery on the spectacle frame, two faces of described liquid crystal lens have the conducting film of layer of transparent respectively, constitute liquid crystal electrode, and two electrodes are electrically connected with the control end of controller; The controller input end is connected to illuminance sensor, to the transducing signal of controller input ambient light illumination; The controller input end is connected to optic angle degree sensor, to the angle sensor signal of controller input external light source.
Principle of work of the present utility model is:
Controller calculates the extraneous intensity of illumination and the incident angle of intense light source by illuminance sensor and optic angle degree sensor, when illuminance during greater than setting threshold, controller is according to the angle of light source, the filaments of sun control voltage that is higher than the upper limit critical value of the responsive control zone control of the even transmittance of eyeglass voltage to liquid crystal lens output one, at this moment, one blanking bar can appear in the eyeglass top that human eye is seen, and this blanking bar can move down with the further rising of voltage, controller can be according to the light-source angle that calculates, automatically the blanking bar of human eye being seen by corresponding filaments of sun control voltage moves on to the position of blocking this light source, plays the effect of blocking high light automatically.
The front was once stated, in the prior art, people utilize the liquid crystal characteristic that even transmittance can reduce with the rising of voltage in certain control voltage range that the penetrability of liquid crystal lens is controlled, promptly evenly in the responsive control zone of transmittance liquid crystal transmittance is being controlled, because after voltage is elevated to responsive control zone control upper voltage limit critical value, evenly transmittance promptly can be not again continue to change with the rising of voltage, so the control voltage to liquid crystal generally all is limited in below the upper limit critical value of the responsive control zone control of even transmittance voltage in the prior art.
But the utility model is noticed a kind of like this physical phenomenon: after control voltage is raised to more than the upper limit critical value, though the even transmittance of whole eyeglass is no longer controlled, but because the angular characteristics of liquid crystal cell and polaroid, when human eye is seen the external world by liquid crystal lens, the shadow striped band that can occur an arch by the top of the eyeglass of an angle setting, and this blanking bar can move down with the further rising of voltage, this blanking bar is relevant with the view directions of human eye, with the range-independence of glasses, so the custom that can wear glasses because of different people and difference occurs not from human eye.
Need to prove: when liquid crystal lens when human eye is very near, although this blanking bar also can present by other direction, but can by rotation this blanking bar fully be presented by horizontal direction according to the directivity of eyeglass, the width that striped presents depends on the distance between eyeglass and human eye.Based on normal distance to lens surface, there is a central angle in the central authorities of striped, and central angle does not depend on the distance between human eye and eyeglass.If the shadow striped is a level, central angle does not change according to the distance between human eye central authorities and the eyeglass top.Therefore, the position that the shadow striped occurs on eyeglass is independently, is not subjected to the mode that glasses wear and the influence of wearer face shape, and every pair of glasses can be worn at large, and need not require that the relative position of regulating between human eye and the eyeglass recalibrates.
The utility model utilizes this characteristic just, when ambient light is strong, utilization is higher than the filaments of sun control voltage of the responsive control zone control of average even transmittance upper voltage limit critical value, is controlled at the position that the filaments of sun occur on the eyeglass, reaches the purpose of dynamically blocking some direction high light.
The new sunglasses of this practicality needn't be to the liquid crystal lens zoning, just can be implemented in the eyeglass part and dynamically block the automatic control of certain orientation high light, and different people is not required the relative position of regulating between human eye and the eyeglass, easy to use, and have simple in structure, the advantage that volume is little.

The filaments of sun control voltage that this example provides is the alternating voltage that frequency is identical, dutycycle is identical, can regulate the height of its effective value by regulating its dutycycle, amplitude or phase place in-migration.
Figure 11 is this routine control waveform figure.
What battery was imported cpu chip is DC voltage, this example utilizes cpu chip and output control terminal able to programme thereof that direct current is become interchange, be added on two control electrodes of liquid crystal, if do the liquid crystal control end with ground of cpu chip and an output terminal, then can not satisfy the requirement that the liquid crystal needs exchange control, this example utilizes two output terminals control liquid crystal can satisfy requirement to AC controling signal.As shown in figure 11, when cell output voltage is V0, the operating voltage of cpu chip is V0 just, and its A output terminal can output amplitude be the square wave of v0 by programmed control, equally to the B output terminal, by programmed control can output amplitude be the square wave of V0, but phase place and A end differ 180 degree, and the A end has just become AC signal with the voltage difference conversion in time of B end, satisfy liquid crystal control requirement, and the output of square wave can be finished with the timer conter in the cpu chip by software programming.
Nearly step this control circuit of ground need be according to the operating voltage on the being added in cpu chip, and substep is controlled the square wave amplitude of two output terminal and mutual phase place, produces required interchange control voltage.
When intensity of illumination is higher than a limit value, microcontroller produces two signals, is added in first signal on first output pin, changes between the reference ground voltage of microcontroller and supply voltage; Second signal on second output pin changes and first signal out-phase between the reference ground voltage of microcontroller and supply voltage, and keeps fixing differing.The dutycycle of two signals is chosen to produce the standard deviation effective voltage value of needs.When intensity of illumination is lower than limit value, when being added in effective voltage value on the microcontroller and being not enough to start it, microcontroller sends with reference to ground voltage to two output pin.
