Description

Electricity causes the instant color-changing protective glasses

The utility model relates to a kind of safety goggles, and particularly a kind of electricity causes the instant color-changing protective glasses.

Traditional light-sensitive glasses, be to adopt chemical material to change the depth of eyeglass according to light intensity, this eyeglass depth amplitude of variation is little, and the sensitivity of reacting condition is relatively poor, the reaction required time is long, for the high light that when meeting at night, runs into as driver grade or when running into high light by day, and can't be moment darkening with eyeglass, high light forces driver's eyes can't open in a period of time probably, might cause traffic hazard.

In view of this, how to make the depth of light-sensitive glasses, make the people have these glasses changing under the situation of light intensity suddenly, be unlikely moment to lose eyesight at the instantaneous variation colour of lens, and sensation light is soft, comfortable when wearing at ordinary times, and the utility model grinds wound motivation place just.

The utility model designer, does a brand-new design and constitutes on the basis of feasibility study repeatedly by means of being engaged in the practical experience that all kinds of optics and electronic equipment are researched and produced processing and other fields for many years, gets generation of the present utility model eventually.

At the deficiencies in the prior art, the purpose of this utility model is that a kind of electricity of realizing that quick power according to surround lighting changes the colour of lens depth of design causes the instant color-changing protective glasses, and simple in structure, still keeps the original style shape of glasses, and is easy to use.

The purpose of this utility model can be by following realization, the utility model is made of spectacle frame, leg of spectacles and eyeglass, it is characterized in that leg of spectacles is provided with battery supply, be provided with colour of lens depth self-actuated controller at the middle part of mirror holder, its control integrated circuit of self-actuated controller IC is connected to power supply, biasing resistor, photodiode, photodiode is arranged in the photographic hole, and the output of self-actuated controller directly connects eyeglass.

Of the present utility modelly further be characterized as the power lead that power supply is connected with self-actuated controller and be provided in a side of in spectacle frame and the leg of spectacles.It is contact metal film that an end is adopted in electrical connection between spectacle frame and the leg of spectacles, and the other end is a resilient contact.

The utility model light harvesting is learned, electronics is the up-to-date high-tech photovoltaic of one, it is slow to have replaced photochromic speed, can not around-the-clock history, it has instant color-changing, and optics is changed automatically, and speed was faster than 1/100 second, when high light, perverse sight, when dazzling light shines suddenly, it is higher than 1/100 second speed variable color, and protection user's eyes are unlikely the injury that is subjected to above-mentioned light; The direct projection light and the reflection ray of chaotic are adjusted into the suitable fill light of human eye; Can prevent caused the having a dizzy spell and PVR of the long-time irradiation of harm rays such as purple, infrared ray, electromagenetic wave radiation, solar radiation, to cause eye illnesses such as visual deterioration, cataract; The driver wears this mirror, be a pair of comfortable sunglasses daytime, drives to see clearly night to look into road conditions, prevents the irradiation of the other side's automobile front lamp high light, perverse sight and dazzling light during meeting again, cause the moment of eyes blind, the traffic hazard of avoiding misoperation to cause; The fishing fan wears this mirror, but jumping light and dazzling light that filtering water surface ripples flash back the sunlight and cause prevent eyes muscular fatigue and the sense of having a dizzy spell, and observe the water surface soft, clear, comfortable for a long time.

Further illustrate the utility model below in conjunction with accompanying drawing embodiment,

Fig. 1 is the utility model structural drawing.

Fig. 2 is the utility model spectacle frame rear view.

Fig. 3 is provided with structural drawing for the utility model leg of spectacles power supply.

Fig. 4 is the utility model automatic control circuit structural drawing.

Fig. 5 is the utility model one-piece construction external form figure.

1...... spectacle frame 2...... leg of spectacles

3...... power supply 4...... photographic hole

5...... hinge 6...... eyeglass

7...... sunk area 8...... contact metal film

9...... resilient contact 10...... power supply lid

11..... capping

The utility model is by spectacle frame 1, leg of spectacles 2 and eyeglass 6 constitute, spectacle frame 1 is connected with leg of spectacles 2 usefulness hinges 5, can fold easily and open, be coated with electrochromic material (commercially available prod) on the eyeglass 6, eyeglass 6 is stuck on the spectacle frame 1, leg of spectacles 2 is provided with battery supply 3, can be on leg of spectacles, to be provided with recessed area, at recessed area battery supply is set, cover with power supply lid 10 again, be provided with colour of lens depth self-actuated controller at the middle part of mirror holder, be provided with a sunk area 7 at the spectacle frame middle part, and be provided with one and connect photographic hole 4, self-actuated controller is located at sunk area, and be provided with capping 11 and cover, self-actuated controller control integrated circuit IC is connected to power supply, biasing resistor, photodiode, biasing resistor is divided into vibration biasing resistor R1, daytime, preset voltage biasing resistor R2 preset biasing resistor R3 evening, daytime and conversion in evening biasing resistor R4, biasing resistor is used to be provided with the basic output voltage of integrated circuit (IC), photodiode D is arranged in the photographic hole, the light power in sensing spectacles the place ahead that can be sensitive, and the output of self-actuated controller directly connects eyeglass, by the power to the lens energising, moment changes the shade of eyeglass.

Of the present utility modelly further be characterized as the power lead that power supply is connected with self-actuated controller and be provided in a side of in spectacle frame and the leg of spectacles, do not expose, it is contact metal film 8 that an end is adopted in electrical connection between spectacle frame and the leg of spectacles, the other end is a resilient contact 9, contact metal film and resilient contact are corresponding respectively, and play an on-off action, when leg of spectacles folds the not time spent, contact metal film and resilient contact are separately cut off the electricity supply; When leg of spectacles opened use, contact metal film contacted with resilient contact, power turn-on.

Spectacle frame and leg of spectacles can be the plastic cement frame, also can be metal frame, when using metal frame, should be provided with insulation course between power lead and electron device and spectacle frame and leg of spectacles contact position.

In sum, basis is novel can utilize simple structural design, utilize the space of leg of spectacles and spectacle frame cleverly, on the basis that does not influence overall appearance, various parts are set, reaching can be according to light intensity and moment changes the shade of eyeglass, applicable to tourism, mountain-climbing, skiing, gas welding, melting, the personnel of outdoor sports under the high light harm ray, especially is fit to automobile, motorcycle, bicycle driving at night and uses.Obviously the utility model is the new design of a kind of novelty, progress and dark tool practicality.The above is specific embodiment of the utility model and the know-why used, if the equivalence of doing according to conception of the present utility model changes, when the function that it produced does not exceed spiritual that instructions and accompanying drawing contain yet, all should be in scope of the present utility model, explanation hereby.
