Abstract
The utility model relates to a glasses protective device. Liquid crystal lenses are arranged in a glass frame. A light sensitive sensor is inlaid on the front side of the glass frame and is connected with the liquid crystal lenses, a Liquid crystal driving circuit, a control switch of critical lighting intensity, a power supply and a power supply switch. The output end of the liquid crystal driving circuit is connected with the liquid crystal lenses. The control switch of critical light intensity is arranged on the back side of the glass frame. The power supply switch in a contact point type is arranged on the adjacent part of glass legs and the glass frame. The utility model is mainly used for sheltering the strong light and can instantaneously and automatically shelter the light and conduct light transmission. The displaying color can be selected. The utility model is suitable for the condition with the sudden change of the light ray, particularly the stimulation of the driver's glasses caused by the strong light in the motor vehicle meeting can be eliminated. The safe vehicle drive is guaranteed. The utility model can also be served as colorful sunglasses.
Description
The utility model relates to a kind of eye-protective system.
When motor vehicles met at night, dazzling light made both sides driver can not normally observe the road surface, and influence is driven, and traffic hazard takes place easily.Though, have some about the automobile meeting automatic device for changing light, because relate to the transformation of auto production line, and automaker is numerous, even also can't overturn the present conditions in indivedual cars employings.
The CNGG85202443 patented claim discloses a kind of electronics shading eyeglasses, is made up of eyeglass, transmission-type liquid crystal horizontal stripe, conductive strips, controller, automatic photoreceptor, hand push button.
The CNGG87210593 patented claim discloses a kind of photosensitive electronic liquid crystal light-sensitive glasses, is made up of diaphotoscope, catoptron, adopts LCD panel to make eyeglass.
The purpose of this utility model be to provide a kind of portable can instantaneous automatic shading, the high light safety goggles of printing opacity, automatic color regulating.
The utility model comprises spectacle frame, liquid crystal lens, light sensor, liquid crystal display drive circuit, critical light intensity gauge tap, power supply and power switch, liquid crystal lens places in the spectacle-frame of spectacle frame, light sensor is embedded at the front of spectacle-frame, and link to each other with liquid crystal lens, liquid crystal display drive circuit, critical light intensity gauge tap, power supply and power switch, the liquid crystal display drive circuit output terminal links to each other with liquid crystal lens.The critical light intensity gauge tap places the spectacle-frame rear side.The contact power switch is located at leg of spectacles and spectacle-frame junction, and when leg of spectacles launched, leg of spectacles made the contact contact, the power switch closure, and circuit is connected; When stopping using, leg of spectacles is folding, and switch contact breaks away from, and circuit disconnects.
The utility model utilizes liquid crystal transparency and Show Color to be subjected to the principle of extra electric field control, utilize LCD panel to make the shading material, liquid crystal drive voltage is provided by liquid crystal display drive circuit, utilize light sensor to respond to extraneous light intensity, and controlling and driving voltage, thereby change liquid crystal transparency and color automatically, make liquid crystal transparency and extraneous light intensity be inverse change.The utility model power utilization common batteries or solar cell for supplying power, when utilizing solar cell, but solar cell double as light sensor, when extraneous light when dying down by force, light sensor is regulated control voltage by high step-down, otherwise, then uprise, thereby the liquid crystal transparency uprised or by high step-down by low by low.Liquid crystal because of printing opacity frequency difference display color, utilizes this characteristic to can be made into the sunglasses of variable different colours in the variable color process.The utility model gauge tap comprises two (critical light intensity gauge tap and power switches), and one is used for regulating critical variable color light intensity, and another is used for cutting off circuit when not in use, plays the effect of protection system.The utility model is used to block high light.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a liquid crystal display drive circuit schematic diagram of the present utility model.
Following examples will be further described the utility model in conjunction with the accompanying drawings.
As shown in Figure 1, the utility model is by spectacle frame (1), liquid crystal lens (2), light sensor (3), liquid crystal display drive circuit (4), critical light intensity gauge tap (5), power supply (6), power switch (7) be connected lead etc. and form.Liquid crystal lens (2) is installed in the spectacle-frame (11), light sensor (3) adopts photosensitive two, the triode of photoresistance formula, and be embedded in spectacle-frame (11) front, and link to each other with liquid crystal lens (2), liquid crystal display drive circuit (4), critical light intensity gauge tap (5), power supply (6), power switch (7).The resistance of light sensor or the output voltage that is provided change with extraneous intensity variations, to reach the purpose of control liquid crystal drive voltage.Liquid crystal display drive circuit output termination liquid crystal lens provides driving voltage.Rheostat critical light intensity gauge tap (5) places spectacle-frame (11) upper end rear side, comes controlling and driving voltage initial value by changing loop resistance, thereby reaches the purpose of regulating critical variable color light intensity.Contact power switch (7) is located at leg of spectacles (12) and spectacle-frame (11) junction, and when leg of spectacles (12) launched, the contact of leg of spectacles (12) leading section extruding power switch (7) made the contact contact, switch closure, and circuit is connected.Otherwise, but automatic shutdown circuit.
As shown in Figure 2, liquid crystal display drive circuit (4) selects for use integrated circuit commonly used to form integrated circuit (IC)
1(NE555P) the 4th, 8 legs meet photodiode D
1Negative pole (2DM), D
1Positive pole be connected to IC through power supply and power switch
