Abstract
The utility model relates to an anti-dazzle daily-used civil electronic color-changeable glasses. It is composed of a pair of eyeglass, a glasses frame, legs, and a regulate and control device. The electronic color-changeable glasses is characterized in that the eyeglass is liquid crystal eyeglass and the glasses frame or the legs are provided with the regulate and control device. The liquid crystal eyeglass is opened and closed through the control of the regulate and control device. The output voltage or current of the photoelectric probe installed in the regulate and control device can be changed with the variation of ambient light, and the output impulse width of electronic circuit is changed consequently and that causes the light transmittance of the liquid crystal eyeglass to be changed with the pulse duty factor so as to realize the purposes of regulating and controlling the light transmittance continuously. The utility model has fast reaction of transmittance regulation and large adjustable extent, and eliminates the all-or-none phenomenon of liquid crystal switch.
Description
The present invention relates to a kind of anti-dazzle and daily civilian electronic color-changing glasses of being used for, it comprises eyeglass, picture frame, mirror leg and regulation device.
Thereby existing anti glare anti static coatings light-sensitive sunglasses change colour of lens to regulate transmittance to reach anti glare anti static coatings protection eyes purpose by chemical reaction.This glasses not only react slowly environmental change, and the transmittance range of adjustment is also less.In addition; " electronics newspaper " TWH8751 Grand Design Prix in 1988 obtains the first prize " optically controlled liquid crystal switch (electric welder uses) "; close the fast characteristics of response according to liquid crystal; utilize TWH8751 to produce switching waveform; liquid crystal is closed when electric welding fully; replace the cover plate on the electric welding protective cover to play the effect of protection eyes with this, but this liquid crystal shutter is still the regulative mode of " all or none ", does not solve pulsewidth regulation and control and printing opacity and changes discontinuous problem.
The objective of the invention is to avoid above-mentioned the deficiencies in the prior art part and provide a kind of fast to environmental change reaction, the printing opacity range of adjustment is big and the electronic glasses of transmittance continuous variable.
Task of the present invention is finished like this: eyeglass adopts liquid-crystalline glasses, it opens and closes by being placed in the regulation device control on the spectacle frame, the power of ambient light changes also changes the output voltage of regulation device photoelectric probe or electric current, the pulsewidth of electronic circuit output changes thereupon, cause that the liquid crystal lens transmittance changes with pulse duty factor, thereby reach the purpose of continuous regulation and control transmittance.
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is a principle of work block scheme of the present invention.
Fig. 2 is a side view of the present invention.
The extraneous light of photoelectric probe (1) impression changes.During high light, photoelectric probe (1) output voltage or electric current raise, and electronic circuit (2) pulsewidth increases, dutycycle changes, liquid crystal lens (3) shut-in time prolongs, and the opening time shortens, thereby printing opacity is reduced, during the low light level, photoelectric probe (1) output voltage or electric current reduce, and electronic circuit (2) is worked hardly or pulsewidth narrows down, and liquid crystal lens (3) opening time is prolonged, shut-in time shortens, and causes printing opacity to increase.Electronic circuit (2) and liquid crystal lens (3) minimal power consumption, little, the lightweight photoelectric cell of available volume (4) is made power supply.Power switch adopts hook switch (5), is installed in picture frame (7) and mirror leg (8) junction, and leg of spectacles during use (8) is opened, and mirror leg (8) contacts with the contact of picture frame (7), the hook switch energized, and circuit is started working.Not the time spent, mirror leg (8) is folding, and hook switch disconnects, and circuit quits work.Glasses are equipped with manual adjustments potentiometer (6), are used to regulate eyeglass primary colours intensity.
The adjustable pulse producer of electronic circuit (2) formation pulsewidth, it is fixed that about 400Hz(appoints between 32～500Hz), dutycycle is by the voltage or the Current Control with the strong and weak variation of light of photoelectric probe (1) output.Liquid crystal lens (3) adopts TN type liquid crystal, also can adopt colored polarization membranous type liquid crystal, guest-host type liquid crystal or plastotype liquid crystal, just as demonstration.For TN type liquid crystal, when pulsewidth changes between 2～6ms, can make liquid crystal, thereby reach the purpose of light modulation toning complete transparent to variation continuously between closing fully.
The present invention compared with prior art has following advantage: owing to adopt liquid crystal technology, make eyeglass printing opacity conditioned reaction fast (the millisecond order of magnitude), adjustable extent big. Because human eye has the vision retention characteristics, therefore, change light transmittance the blanking time that opens and closes by the control eyeglass, and glasses just can be felt the continuous variation of light, thereby eliminated " all or none " phenomenon of liquid crystal shutter.
Claims (3)
