The utility model solves the problems of short service life of batteries low light transmittance ratio at nighttime, unintelligible vision and bulky and inaesthetic glasses frame structure existing in the prior art. The utility model can be widely applied to fields, such as sun glasses, field workers, climbing, skiing, sailing, automobile driving, etc.

Description

A kind of novel light-operated electrochromism glasses

A kind of novel light-operated electrochromism glasses connects hinge frame (7), switch (8) formation by picture frame (1), mirror leg (2), eyeglass (3), silicon photocell (4), button cell (5), driving circuit and wiring board (6), picture frame, mirror leg, picture frame (1), the plastic material of mirror leg (2) for insulating, connecting hinge frame (7) is conductive metallic material.The utlity model has delicate structure; power consumption is extremely low; can make eyeglass incident light illumination adapt to human eye all the time according to the automatic adjusting of the strong and weak variation of ambient light eyeglass transmittance not stimulated by high light; thereby reach the purpose of protection eyes; can be widely used in sunglasses, field worker, mountain-climbing, ski, fish, every field such as driver, researcher, can round-the-clockly use.

New through looking into, existing similar products like and technical literature data are as follows: Chinese patent 91218993 " electricity causes the adjustable transmission safety goggles of instant color-changing ", 93216077 " electronic color-changing glasses ", " 95235119.6 electronic liquid crystal light-sensitive glasses ", " 94219344.X multi-functional quick light-sensitive sunglasses ", 95202363.6 " anti-glare glasses " etc. all is to adopt the liquid crystal lens metachromatic principle, use button cell power supply exists under night or the low-light (level) environment eyeglass transmittance low, blurring of vision is clear, battery serviceable life, short or complex structure was heavy not attractive in appearance and use many shortcomings such as inconvenience.

The utility model has overcome above shortcoming, adopt button cell and silicon photocell dual power supply, utilize sun power to provide power driving circuit make eyeglass variable color by silicon photocell daytime, and silicon photocell voltage is higher than button cell voltage by day, therefore silicon photocell can charge to button cell by day, power by button cell during the occasion silicon photocell undertension of night or low-light (level), prolonged the serviceable life of battery greatly; The eyeglass color change interval is divided into two parts up and down, top is to drive to meet the high light color change interval night, this zone can be when meeting at night opposite car light irradiation intensity regulate transmittance automatically and block the headlight for vehicles high light, and eyeglass keeps higher transmittance can clearly observe the road surface in this extra-regional bottom variable color hardly.By day or the occasion eyeglass of high brightness can whole variable color, and the relative transmittance of eyeglass can be regulated in 10%～90% scope automatically according to the light intensity situation of change.Like this, no matter under which type of situation, the utility model glasses are can anti glare anti static coatings dazzling, can keep the good thing sharpness of looking again.

To and contrast accompanying drawing by embodiment below the utility model will be done further narration.

Fig. 1 is a picture frame front view (FV) of the present utility model.There were a little square circuit box, built-in driving circuit wiring board (6) and switch (8) in the top in the middle part of eyeglass (3), silicon photocell (4), the bridge of the nose were housed on picture frame.The button cell electrode links by lead (1.1) and wiring board (6), and lens electrodes links to each other with wiring board (6) by hole (1.2).Wiring board (6) is hidden in the circuit box of middle part.

Fig. 2 is a mirror leg structural representation of the present utility model, and mirror leg tail end has a battery case, and interior dress button cell (5), the both positive and negative polarity of battery are sent to picture frame mirror leg by built-in lead (2.1) and connect (2.2) and (2.3) of cutting with scissors on the frame (7).The structure that connects hinge frame (7) is that (7.1) on the turning joint (2.2) that a metal is arranged on the mirror leg (2) and picture frame link to each other with screw, another electrode on the mirror leg (2) is a Metallic rod (2.3) that has inner spring, can stretch behind the pressurized, launch this Metallic rod behind the mirror leg and can snap in tightly in the groove (7.2) on the picture frame because of the elastic force effect of inner spring, (7.1) and (7.2) link to each other with lead (1.1) on the picture frame respectively.Separate with (2.3) (7.2) after closing up the mirror leg, is equivalent to power switch and disconnects, and can play power supply power supply when wearing glasses, and takes off one's glasses to close up the just on-off action of outage of mirror leg.

Fig. 3 is the lens structure synoptic diagram, and the eyeglass color change interval is made up of two parts (3.1) and (3.2).Two parts are variable color, variable color separately again simultaneously both.Daytime is (3.1) and (3.2) variable color simultaneously when using, and have only (3.1) variable color of the first half to block headlight for vehicles high light when driving to use night, and the Lower Half nondiscolouring keeps transparent can clearly observe the road surface target.Its eyeglass by two transparency carrier surface-coated nesa coatings after in the middle of accompany transmission-type liquid crystal material or electrochomeric films (as WO ₃Deng) combine.

Fig. 4 is the structural representation of silicon photocell (4).This silicon photocell is made up of two parts (4.1) and (4.2), (4.1) be by several small silicon photocell strings and form as solar cell of the present utility model and use that (4.2) are two independently silicon photocells, make light sensor and use, one is used for daytime, and one is used for night.The use electrode of silicon photocell and driving circuit wiring board (6) directly link together with conducting resinl.

Fig. 5 is the driving circuit schematic diagram.Form by power supply (5.1), optoelectronic switch (5.2), drive integrated circult (5.3).Wherein power supply is formed in parallel by a diode (D) and button cell (5) by silicon photocell (4.1).
