Embodiment:
Fig. 1 is circuit theory diagrams of the present utility model, it has comprised crystal silicon solar batteries assembly (1-1) and driving circuit as power supply, with the prior art scheme relatively, four parts have been increased: promptly as the electric capacity of impact damper (1-3), as the crystal diode (1-4) of voltage maintainer, put upside down crystal diode (1-7) in parallel as the resistance (1-6) of alternate evener and as 2 positive and negative electrodes of pulse current amplitude sequential balanced device.Below each part is described in detail:
At first say impact damper.When not having impact damper in the circuit, the sensitive surface of crystal silicon solar batteries assembly (1-1) is by any object is of short duration when covering sunlight, liquid crystal glasses sheet (1-8) " moment is eclipsed relatively " all can take place because of the erroneous judgement surround lighting dies down in system, causes high light to see through, and stimulates eyes.In the feeder ear parallel connection of pulse producer (1-5) after the electric capacity as impact damper (1-3), when the sensitive surface of crystal silicon solar batteries assembly (1-1) by any object is of short duration when covering sunlight, function by the interim power supply of impact damper (1-3) performance, liquid crystal glasses sheet (1-8) just obtains time-delay shown in Fig. 2 curve A, " moment is eclipsed relatively " can not take place, and problem is solved.
Introduce the voltage maintainer below.When not having voltage maintainer (1-4) in the circuit, crystal silicon solar batteries assembly (1-1) sensitive surface is after change dorsad the sun into towards the sun, impact damper (1-3) not only can but also can discharge by crystal silicon solar batteries assembly (1-1) and voltage increment rejector (1-2) by pulse producer (1-5) discharge, and the resistance value of the latter two is much smaller, and the electric charge major part in the impact damper (1-3) has been missed from these two passages.In order to block this two leak channels, will making alive maintainer (1-4).Voltage maintainer (1-4) is a crystal diode that forward uses with respect to current supply circuit, and it is linked to be a loop with the feeder ear three of the former crystal silicon solar assembly (1-1) that has been connected in parallel, voltage increment rejector (1-2) and the impact damper (1-3) that is connected in parallel separately, pulse producer (1-5).Curve B from Fig. 2 installs the contribution that voltage maintainer (1-4) is done delay function as can be seen additional.
Preamble is mentioned, and in order to overcome liquid crystal glasses sheet (1-8) " moment is eclipsed relatively ", has added the electric capacity as impact damper (1-3) in the circuit.But after having added this electric capacity, can bring out the disadvantage of " stroboscopic ".The method that overcomes " stroboscopic " is a serial connection pulse current amplitude sequential balanced device (1-7) in the loop of liquid crystal glasses sheet (1-8).It is to put upside down crystal diode formation in parallel by 2 positive and negative electrodes that are serially connected in liquid crystal glasses sheet (1-8) loop, and Fig. 5 is its E-I characteristic.If when use was insufficient, pulse current amplitude sequential balanced device (1-7) can overlappingly use.
Introduce alternate evener below.Alternate evener (1-6) is the resistance of cross-over connection between two output terminals of pulse producer (1-5).Its task is to overcome " hickie " phenomenon.The signal that drives liquid crystal glasses sheet (1-8) must be the bidirectional pulse of positive and negative symmetry, needs balance just as three-phase electricity.If the bidirectional pulse of positive and negative symmetry has lacked a phase, out of trim, just can make the liquid crystal material polarization, evenly variable color produces " hickie ".Added after the resistance as alternate evener (1-6), pulse producer (1-5) has had a linear load, is lower than the threshold voltage U of liquid crystal glasses sheet (1-8) in its voltage pulse output amplitude
ThThe time, pulse producer (1-5) is normally starting of oscillation just, exports the bidirectional pulse of positive and negative symmetry, treats that pulse voltage is elevated to U
ThDuring value,, two-phase successively reaches U though still having
ThDifference, of short durationly discovered to being difficult to, " hickie " problem is readily solved.
For overcoming the shortcoming of liquid crystal glasses sheet (1-8) in the prior art, the utility model has been done following substituting improvement: prior art adopts the normal temperature liquid crystal material, adapting to operating temperature range is 0 ℃ to+40 ℃, and the utility model employing adaptation operating temperature range replaces for-20 ℃ to+70 ℃ wide temperature liquid crystal material (3-4); The polaroid hardness that prior art adopts is lower than 1H, be subject to scratch, ultraviolet ray mean transmissivity＜10% blocks insufficiently to ultraviolet ray, the uvioresistant stiffened polaroid (3-2) that the utility model adopts hardness to be higher than 2H and ultraviolet mean transmissivity＜1% substitutes; The wadding that prior art adopts is white, and it can make eyeglass produce very strong spoke sample radiance, seriously interrupts the view, and the utility model has adopted black wadding (3-7) to substitute, and spoke sample radiance are suppressed to some extent.The utility model is coated with anti-scratch blooming (3-1) on liquid crystal glasses sheet (1-8) two surfaces, its hardness is that 6H to 8H further improves the scratch resistance ability.
