Abstract
The utility model relates to a pair of electronic liquid crystal color changing glasses, comprising two pieces of liquid crystal eyeglass, a glasses frame, a connecting plate body, a picture shooting device, a photoelectric conversion controlling circuit, a fixed plate, etc. Light signals entering from the picture shooting device is converted to electric signals by the photoelectric conversion controlling circuit to control the color changing of the two pieces of liquid crystal eyeglass to achieve the purpose of weakening strong light. The utility model solves the problem that the color of liquid crystal glass can only be changed integrally and can not be changed partly existing in the prior art. The utility model is a pair of ideal color changing glasses suitable for the fields such as automobile driving, etc.
Description
The utility model relates to a kind ofly controls the glasses of eyeglass variable color, particularly a kind of electronic liquid crystal light-sensitive glasses by electronic circuit.
At present, general light-sensitive sunglasses of Shi Yonging all can only wholely become light, can not locally as required become light, do not need the part of variable color during use in the eyeglass, also can variable color, and light also correspondingly weakens, and influences visibility.The patent disclosure of application number 87210593 a kind of photosensitive electronic liquid crystal light-sensitive glasses, it is made of eyeglass, mirror holder two parts.Its eyeglass is the nematic crystal sheet, and light-operated liquid crystal film extra electric field generating means is housed on the mirror holder.By the effect of extra electric field generating means, along with the power variation of illumination, the LCD panel color also produces the variation of the depth.The major defect of its existence is that LCD panel can only wholely become light, can not locally become light.
The purpose of this utility model just is at the deficiencies in the prior art part, and a kind of electronic liquid crystal light-sensitive glasses are provided, and can make the local variable color of liquid crystal lens, thereby the high light line is died down, and decreased light intensity is unaffected.
The purpose of this utility model is achieved through the following technical solutions.The electronic liquid crystal light-sensitive glasses comprise liquid crystal lens, mirror holder, connection plate body, picture pick-up device, opto-electronic conversion control circuit, fixed head and set collar.Eyeglass, mirror holder all support by connecting plate body, connect between plate body and the fixed head to flexibly connect.Picture pick-up device, opto-electronic conversion control circuit are fixed on the fixed head.
Above-mentioned opto-electronic conversion control circuit comprises CCD electrooptical device, V address scan circuit, H address scan circuit, luminance signal analysis circuit, intednsity circuit and LCD liquid crystal lens.V address scan circuit, H address scan circuit can be simultaneously to CCD with LCD is capable and the scanning of location, place, enter the brightness analysis circuit from the data of CCD output, and the effect by intednsity circuit, the brightness of control LCD corresponding point.
The electronic liquid crystal light-sensitive glasses comprise that also the mirror that is connected with described mirror holder is apart from regulating assembly.It is made of right mirror holder tooth bar, left mirror holder tooth bar, gear and adjusting knob.Right mirror holder tooth bar and right mirror holder are connected as a single entity, and left mirror holder tooth bar and left mirror mirror holder are connected as a single entity.Right mirror holder tooth bar, left mirror holder tooth bar all with gearing mesh.Gear is an one with regulating knob, and gear, adjusting are revolved carefully and cooperated with the gear shaft bearing, and the gear shaft axle head is fixed on and connects on the plate body.
The utility model compared with prior art has following technique effect: 1. under the effect of opto-electronic conversion control circuit, the whole variable color of liquid crystal lens energy also can local variable color.The high light line is died down, and decreased light is not suffered a loss, and has both avoided high light dazzling, has improved visual capabilities again.2. used circuit little power consumption adopts button cell just can keep operate as normal.
Fig. 1 is a structural representation of the present utility model.Fig. 2 is its A-A diagrammatic cross-section.Fig. 3 is the circuit part block scheme.Fig. 4 is a circuit connection diagram.
Below in conjunction with accompanying drawing in detail the utility model is described in detail.The electronic liquid crystal light-sensitive glasses comprise liquid crystal lens 1, mirror holder 2, connect plate body 3, picture pick-up device 4, opto-electronic conversion control circuit 5, battery case 6, fixed head 7, set collar 8 and mirror apart from regulating assembly 9.Mirror comprises right mirror holder tooth bar 10, left mirror holder tooth bar 11, gear 12 and regulates knob 13 apart from regulating assembly 9.Liquid crystal lens 1 is fixing by mirror holder 2.Mirror holder 2 comprises right mirror holder and left mirror holder two parts, and right mirror holder and right mirror holder tooth bar 10 are connected as a single entity, and left mirror holder and left mirror holder tooth bar 11 are connected as a single entity.Right mirror holder tooth bar 10 meshes the coboundary engagement of left mirror holder tooth bar 11 and gear 12 with the following edge that connects of gear 12.Gear 12 revolves thin 13 with adjusting and is connected as a single entity, and be gear shaft in the middle of it, gear 12, regulate revolve thin 13 with gear shaft between bearing cooperate, the gear shaft axle head is fixed on the connection plate body 3.Connect the box that plate body 3 is formed for doubling plate, be connected with pivot pin on it with between the fixed head 7, plate body 3 like this can be rotationally connected up and down.At connection two ends, plate body 3 left and right sides slit is arranged, the right-hand member of the left end of left mirror holder tooth bar 11, right mirror holder tooth bar 10 all stretches out above-mentioned slit.Left side mirror holder tooth bar 11, right mirror holder tooth bar 10 can only move by along continuous straight runs it, and can not vertically move by connecting plate body 3 and gear 12 actings in conjunction.Adopt above version, regulate knob 13 as long as rotate, the distance about just can regulating between two eyeglasses is to reach visual effect preferably.In the time need not using liquid crystal glasses, as long as the plate body 3 that upwards is rotationally connected, can drive eyeglass 1, mirror holder 2, mirror apart from regulating assembly 9 and is connected plate body 3 and forwards eyes top together to, when needing to use, be rotated down connection plate body 3 and cover eyes and get final product.
Above-mentioned picture pick-up device 4, opto-electronic conversion control circuit 5, battery case 6 all are installed on the fixed head 7, on the set collar 8 fixed band are arranged, and whole liquid crystal color-changing glasses are fixed in head.
Opto-electronic conversion control circuit 5 comprises CCD electrooptical device, V address scan circuit, H address scan circuit, luminance signal analysis circuit, intednsity circuit and LCD liquid crystal lens.From light signal imaging on the CCD electrooptical device that picture pick-up device enters, by V address scan circuit, H address scan circuit simultaneously to CCD with LCD is capable and location, place scanning.Because same address generator circuit is adopted in V and H scanning, so do not need other synchronizing circuit.Enter the luminance signal analysis circuit from the pictorial data Dnc of CCD output, when brightness meets or exceeds the threshold level of setting, intednsity circuit effect, output control signal D
Nl, D
NlThe corresponding point of control LCD changes its brightness.When luminance signal was high more by threshold level, the prosperous eyeglass LCD of liquid changed more greatly, when luminance signal during all by threshold values, had just reached whole change light.
