Description
Technical field
The utility model belongs to a kind of glasses, but is specifically related to a kind of sunglasses of automatic color-changing.
Background technology
For the protection eyes are not stimulated by extraneous high light; wearing the color-changing solar mirror is one of normal preventive measure that adopt of people; traditional light-sensitive glasses are to adopt photochromics to make eyeglass; utilize light to the characteristic of variable color to regulate the eyeglass transmitance; the light-sensitive sunglasses of light sensitive characteristic are usually operated at the ultraviolet light wave band, are containing under the sunlight of ultraviolet light, and photochemical reaction takes place in its eyeglass; make the eyeglass transmitance descend the eyeglass deepening.As color-changing solar mirror of Transition brand etc.
But these class light-sensitive glasses are running into surrounding environment light when sudden change, and as in the inlet chamber and tunnel etc., transmitance that can not very fast automatic adjusting eyeglass causes the user sight line to weaken, the environment around not seeing.This is because the variable color time of photosensitive colour-changing sunglasses is generally several seconds to tens seconds scope; And fading time is slightly long, generally the scope to dozens of minutes in a few minutes.Regulate with people's pupil and to change the needed time with adaptating lighting and compare, its response time is oversize.The demand that can not adapt to human eye.And these class glasses are filtering under the sunlight of ultraviolet quilt, and the chemical reaction of variable color just can not take place, and for example in the windshield back, although sunlight is dazzling, glasses just can not deepening.
Another kind of sun light-sensitive glasses are to make eyeglass with liquid crystal in the prior art, be added in the light transmission rate of the voltage change eyeglass on the liquid crystal lens by change, these class sun light-sensitive glasses all need to be provided with battery usually, light intensity sensor, A/D change-over circuit exclusive disjunction amplifier, square-wave generator etc., switch perhaps is set is added in control voltage on the liquid crystal lens with manual change, exist the Circuits System volume excessive, the problem that power consumption is big, and the essential periodic replacement of battery, both increased the use cost of glasses, and the excessive use of volume is very inconvenient again, so restricted this type of electronic glasses, also be that this series products is not seen one of major reason that commodity go on the market so far as the feasibility that the product for civilian use uses.
Summary of the invention
The technical problems to be solved in the utility model is to overcome above-mentioned deficiency, provide a kind of and can change the full-automatic automatically controlled variable color liquid crystal sunglasses that changes the eyeglass transmittance with extraneous light intensity in real time, this sunglasses can be realized realizing becoming light with the speed with human eye pupil dilation time coupling, and have simple in structure, volume is little, little power consumption, advantage that use cost is low.

The transmitance of liquid crystal lens in visible-range is relevant with control voltage on being added in its two electrode: when control voltage surpasses the control voltage threshold of setting and be lower than the setting maximal value of control voltage, transmitance can reduce with the rising of control voltage, utilize this characteristic, such scheme is controlled the voltage that is added on the liquid crystal lens with control module, reaches the purpose of variable color; And the utility model utilizes the opto-electronic conversion battery to have transform light energy is electric energy, and its output voltage can be with the characteristic of intensity variation,, for providing light transducing signal and power supply, control module that is to say with a kind of parts of light Electroconversion cell to have replaced conventional batteries and two kinds of functions of components of light intensity sensor with the light Electroconversion cell.
Its principle of work is:
When the voltage of opto-electronic conversion battery reception solar energy generation was lower than the operating threshold threshold voltage of control module number setting, control module was in dormant state, does not have control signal output; This moment, the transmitance of liquid crystal lens reached its maximal value; When the voltage of opto-electronic conversion battery reception solar energy generation surpasses the operating threshold threshold voltage of control module, the output terminal of control module is the control voltage that output amplitude changes with input voltage, at this moment the transmitance of liquid crystal lens descends with the increase of control voltage, ambient light illumination is strong more, control voltage is high more, and the eyeglass transmitance is just low more.Thereby realize the automatically controlled fully-automatic conversion light of sunglasses.
The utility model can be regulated the transmissivity of eyeglass automatically according to ambient light, when ambient light illumination uprises, the transmitance step-down, during ambient light illumination step-down, transmitance uprises, the eyeglass transmissivity can be in real time change with the electric signal of control, and the control electric signal changes with the difference of ambient light, thus these glasses can be in real time with the variation of ambient light illumination the adjusting illuminance that enters human eye automatically.
Light-sensitive glasses both should not be too slow to the response time of high light; also should not be too fast; transformation period the eyeglass scintillation can occur too soon; too slowly can not change with extraneous light intensity in real time again; only adjust the eyeglass shading value with appropriate responsive speed; the variation of illuminance and the expansion time of human eye pupil are complementary, and protection wearer eye pupil need not sharply be expanded and be shunk.Existing photosensitive colour-changing sunglasses is slower to the response time of light, does not reach this requirement, and the utility model can not only overcome this problem, improves response speed, but also can will be transferred to moderate speed to the reaction time of high light by the adjusting to control module.
The centre wavelength of visible light is 550nm, the utility model can be by selecting the opto-electronic conversion battery to the visible light wave range sensitivity for use, reach make liquid crystal lens to the response of visible light wave range and human eye to the essentially identical purpose of the reaction of spectrum, thereby guarantee that eyeglass can automatically adjust to different spectral response according to human eye, and the utility model is to the visible light spectrum sensitivity, promptly can not resemble some photosensitive colour-changing mirrors must could drive by ultraviolet light, this sunglasses equally can be worked under the sunlight of filtering ultraviolet wavelength, as in the automobile etc.
The utility model need not to be provided with switch, light intensity sensor and external battery, the opto-electronic conversion battery that is adopted can serve as light intensity sensor, can power for control circuit again, thereby greatly simplified circuit structure, dwindled volume, and reduced the current drain of automatically controlled part, the utility model can only get final product drive control module is regulated eyeglass transmittance, realization automatic color-changing automatically according to extraneous light intensity purpose with a solar cell that is embedded in the spectacle frame, not only reduce cost of manufacture, also reduced use cost.
