Embodiment
In order to make those skilled in the art understand better the technical solution of the utility model, the utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The utility model has the novel liquid crystal glasses of autozoom function and dimming function simultaneously, be that liquid crystal sunglasses comprises mirror holder and the eyeglass that is installed on the mirror holder, wherein mirror holder can be existing common mirror holder, the eyeglass that liquid crystal cell forms is the liquid crystal boxlike Zoom liquid crystal lens of continuous vari-focus or discontinuous zoom, wherein but but continuous magnification lens is Fresnel type, graded index type or wavestrip type continuous magnification lens, and the discontinuous zoom lens are the discontinuous zoom lens of stepping focusing.Following emphasis is described eyeglass.
Simultaneously referring to Fig. 1 ~ Fig. 3, eyeglass comprises upper substrate 2 and infrabasal plate 7, between the two with the spatial accommodation of glue frame 5 encapsulation formation in order to filling liquid crystal 4, so that encapsulated liquid crystal 4 between upper substrate 2 and the infrabasal plate 7, form thus liquid crystal boxlike zoom lens, wherein: upper substrate 2 inner surfaces are provided with upper substrate electrode 3, and upper substrate 2 outer surfaces post polaroid 1; Infrabasal plate 7 inner surfaces are provided with infrabasal plate electrode 6, and infrabasal plate 7 outer surfaces post lower polaroid 8; This upper substrate electrode 3 and infrabasal plate electrode 6 are connected to respectively control chip, this control chip can corresponding switching zoom mode/light-modulating mode, it is according to zoom/dimming control signal, press the corresponding output electrode driving voltage of preset strategy with 4 deflections of control liquid crystal, carry out zoom and carry out light modulation by the polarizing angle that changes liquid crystal 4 by the refractive index that changes liquid crystal 4, thus to realize autozoom and with an automatic light meter, so that sunglasses possesses zoom function and dimming function simultaneously.Wherein, whole lens area all has light intensity by driving voltage control and adjusts function, and wherein the control of the driving voltage of eyeglass zoom area is independent of other Region control, to realize not affecting Zoom control in the brightness adjustment control.
Below the varifocal liquid crystal sunglasses method for making implementation of the utility model briefly is described:
At first, according to present liquid crystal Zoom Theory, appropriate area 11(at liquid crystal cell (being eyeglass) is called regional A herein, as shown in Figure 2), make the formation zoom lens and (but be preferably continuous magnification lens, such as Fresnel type, graded index type, wavestrip type etc.), realize the function of automatic zoom spectacles.
Then, on the basis of realizing the autozoom function, the outside surface of past its upper and lower substrate respectively pastes one deck polaroid.When the driving voltage of upper substrate electrode 3 and infrabasal plate electrode 6 changes, cause that the liquid crystal deflection angle changes, namely the polarization angle of the polarization angle of liquid crystal molecule and polaroid is variable under driving voltage control, so just can realize the effect that light intensity is to external world regulated, namely realize the function of sunglasses.
But, because polaroid does not cover above-mentioned zone A fully, can cause like this zoom lens when main use zoom function, light intensity can weaken (because the function of sunglasses works simultaneously) also simultaneously, even weak to being not enough to see clearly object, thereby so that use limited.
For this reason, more preferably with the position punching of upper (or lower) polaroid corresponding to regional A, claim that with the remaining part of polaroid regional B(as shown in Figure 2).Namely offering eccentric circular hole at upper polaroid 1 or lower polaroid 8 is light hole 12, and the opening area A of this light hole 12 is the zoom area of liquid crystal cell corresponding to zoom lens, the generation of insufficient light problem in the time of so just can avoiding above-mentioned zoom.
In order to realize better autozoom and light modulation, need the varifocal liquid crystal sunglasses control circuit of the utility model partly is optimized design, be summarized as follows:
As shown in Figure 3, the concrete control circuit connected mode of this sunglasses is as follows: control chip (IC) is connected with photo-sensitive cell, photo-sensitive cell detects extraneous light intensity and is converted into corresponding electric signal and exports IC to, so that IC corresponding control light modulation when extraneous light intensity is stronger, corresponding control focusing when extraneous light intensity is normal, wherein the former ambient light is powerful in the first default light intensity preset value, the latter represents that ambient light is powerful in the second default light intensity preset value, and the described first default light intensity preset value is greater than the described second default light intensity preset value.More preferably, comprise the opto-electronic conversion battery that is installed on the mirror holder central part, its output terminal is connected to storage capacitor (scheming not shown), is the power supply of IC and photo-sensitive cell thus, guarantees that input supply voltage is stable.In addition, be provided with gauge tap (scheming not shown) outside going back, can be button or shifting block, with output zoom/dimming control signal, so that the switching of control zoom and dimming function.
The course of work of this control circuit is: the photo-sensitive cell on the glasses, can experience extraneous light intensity and light intensity magnitude is converted into corresponding electric signal: when extraneous light intensity is stronger, photo-sensitive cell sends signal to IC, and control IC carries out the adjusting of sunglasses " black degree " by regulation voltage pulse-length modulation (PWM) signal; When extraneous light intensity was normal, photo-sensitive cell sent signal to IC, and IC so that liquid crystal deflects, forms certain index distribution by regulating the driving voltage of a-quadrant thus in the a-quadrant, thereby realized the adjusting of focal length.
By with upper type, this enforcement is novel can be possessed zoom function and dimming function simultaneously, and the novel glasses that can intelligence between two kinds of functions switches, and has satisfied preferably thus consumer demand, has good market outlook.
Only be preferred implementation of the present utility model below, should be pointed out that above-mentioned preferred implementation should not be considered as restriction of the present utility model, protection domain of the present utility model should be as the criterion with the claim limited range.For those skilled in the art, within not breaking away from spirit and scope of the present utility model, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
