Abstract
The utility model relates to a pair of glare-preventing and light-controlling liquid crystal glasses, and is composed of a glasses frame, liquid crystal lenses, a regulating and controlling device, a forward sight optical sensor, a background optical sensor, a regulating and controlling groove cover, legs and an automatic switch, wherein the liquid crystal lenses are divided into an upper picture and a lower picture which are respectively controlled by the frontward sight optical sensor and the background optical sensor. Before nighttime meeting, both the two pictures of the lenses are lucent and users can observe the condition clearly; while meeting, only the upper picture instantly changes into a dark screen with deep color to ensure the blocking of bright light and clear viewing to road surfaces. During day, both the two pictures are in deep dark color, and the glasses can be used as sun-glasses or protective glasses for a view screen. The utility model is easy in use because the automatic switch is adopted and the switch of the power supply is realized along with the opening and the closing of the legs.
Description
The utility model is a kind of anti-dazzle optically controlled liquid crystal glasses.
In existing technology, the lens structure of optically controlled liquid crystal glasses has two kinds, and the one, form by a view picture single-image liquid crystal cell, the 2nd, form or form by the upper half liquid crystal lens and following half glass mirror by former and later two liquid crystal cells.The former defective is that liquid crystal lens is under the details in a play not acted out on stage, but told through dialogues situation when meeting, though can block the headlight high light that the opposite is come, reaches anti-dazzle purpose; But because the liquid crystal lens transmittance is generally below 25% at this moment, whole visual field is dim.Therefore the scenery of the road surface, the place ahead and the both sides of sending a car is difficult to see clearly, and the driver is not satisfied.The latter's deficiency is that manufacturability is too poor or cost is higher, weight is excessive, can not satisfy the basic demand such as durable, light and handy and attractive in appearance of glasses.
In view of the problem of above-mentioned existence, the purpose of this utility model provides a kind of novel liquid crystal lens.Satisfy the requirement of driver's driving at night fully---" both blocked high light, and seen the road surface again clearly ", thus reach the purpose of safety and comfort and anti-dazzle eyeshield simultaneously.
Solution of the present utility model is: a kind of anti-dazzle optically controlled liquid crystal glasses comprise liquid crystal lens and the mirror holder of being made up of picture frame and mirror leg; The regulation device system of control liquid crystal lens is made of the on-off circuit that light activated element triggers, be located in the regulation and control vallecular cavity of mirror holder, its power supply then places mirror holder, its crucial innovation part is that the picture of liquid crystal lens is divided into up and down two partly with isolation trench, two pictures are respectively by forward sight light activated element and the control of bias light photosensitive elements, the former only accepts front light, and the latter then only accepts other direction light except that the place ahead.The top picture is little, is the anti-dazzle district of shading; Bottom picture is big, for logical light increases vision area.The size of left and right sides liquid crystal lens two top pictures and position can be inequality, asymmetric.Before not meeting high light or meeting night, two ones all are in the bright field state about the liquid crystal lens, and the transmittance of two pictures is all than higher; Therefore whole liquid crystal lens get a clear view brightly, the place ahead scenery is perfectly clear.When meeting the place ahead high light or sending a car headlight, the forward sight light activated element is shone by front light when prominent, triggers regulation device control liquid crystal lens moment to be converted into the details in a play not acted out on stage, but told through dialogues state by bright field, and the transmittance of the anti-dazzle district of shading picture is descended significantly.Because physics filter subtracts the result who closes picture with physiology, the upper center in the visual field forms a dark color secretly shields, and the place ahead high light or meeting headlight is blocked, thereby play the effect of anti-dazzle eyeshield.At this moment, because the bias light photosensitive elements is not subjected to the irradiation of the place ahead high light or the headlight of sending a car, so the bottom of liquid crystal lens still is in the bright field state, the transmittance that logical light increases vision area still occupies high constant; Therefore, send a car both sides and road surface, the place ahead, opposite is in the outer bright areas of the dark dark screen in visual field always, and it is absolutely clear that the driver sees.People looked forward to and needed this visual effect of coping with shifting events by changing, treating with a certain discrimination just.To daytime, forward sight light activated element and bias light photosensitive elements are subjected to rayed equally, and two ones all are in the details in a play not acted out on stage, but told through dialogues state about the liquid crystal lens.The transmittance of whole image all descends significantly, as same sunglasses eyeglass, can be used as sunglasses and screen protective glasses.
In order further to reach the purpose of this utility model, change optically controlled liquid crystal glasses power switch into aut.eq. by hand.Concrete scheme is the opening and closing position that the power switch contact is placed picture frame and mirror leg respectively, and two contacts have at least one to be resilient contact.When wearing spectacles, mirror leg and picture frame meet at right angles, the contact of two contacts, line conduction, power-on.And after taking off one's glasses, the angle of cut of picture frame and mirror leg is in case less than the right angle, two contact separation, and circuit disconnects, powered-down.
For realize the purpose of this utility model more satisfactoryly, to holding the regulation and control vallecular cavity building block of regulation device---regulation and control groove lid has been done improvement, solution by by two plate shapes roughly symmetry, can split cover plate that push-and-pull to center line joins and forms the regulation and control groove and cover.Do like this and can enlarge liquid crystal lens and connect chuck root size, help improving intensity; And be easy to making, assembling, good airproof performance.
The utility model compared with prior art has following advantage:
1. adopt two picture liquid crystal lens, realize that anti-dazzle district of shading and logical light increase setting up separately of vision area, significantly improve the preceding visual field of meeting sharpness; Both effectively blocked the headlight high light during meeting, anti-dazzle eyeshield is seen clearly again and is sent a car on every side and road surface, the place ahead, guarantees safety.
2. adopt to be subjected to the different light activated element of light direction to control two pictures respectively, realized the round-the-clock use of these glasses, enlarged the scope of application and the market of product.
3. adopt the automatic switch of original creation, improved the comfort easy to use and the safe reliability of operation of product.
Fig. 1 is the front view of structural representation of the present utility model.
Fig. 2 is a backsight structural representation of the present utility model.
Fig. 3 is the structural representation of the utility model automatic switch.
The utility model is described in further detail below in conjunction with accompanying drawing.
Embodiment: referring to Fig. 1, sequence number (1) is that picture frame, (2) are that liquid crystal lens, described regulation device (3) and forward sight light activated element (4) place in the nose-bridge frame of picture frame (1) middle part.Dark place, liquid crystal lens (2) picture upper end is the anti-dazzle district of top shading, and all the other increase vision area for the logical light in bottom.
Referring to Fig. 2, sequence number (5) is the bias light photosensitive elements, and (6) are regulation and control groove lids.
