Problems solved by technology

[0002] In order to avoid the irritation of the eyes caused by the instantaneous strong light and unnecessary accidents, people have invented various eye protection devices. The Chinese utility model patent, the patent number 93221282.4, is named "LCD for avoiding the instantaneous strong light" Protective glasses", discloses a liquid crystal protective glasses, including liquid crystal spectacle lenses, and a battery fixed together with them on the spectacle frame, a photoelectric conversion circuit and a liquid crystal driver. The photoelectric conversion circuit is composed of a photoelectric The sensor, the conversion amplifier that adjusts and amplifies the current and voltage signals, the LCD voltage controller and the liquid crystal LCD driver are composed. The structure of the protective glasses is too complicated. People lack comfort when wearing the glasses, and increase the production cost of the glasses, so there is a need for improvement

Embodiment Construction

[0011] Such as figure 1 It is a structural diagram of the light-controlled liquid crystal glasses of the present application, including a liquid crystal lens 1, a bracket 2 for fixing the lens, with integrated electronic devices and circuits inside, and a beam bracket 3, which has a circuit inside and connects with the liquid crystal lens. Hang up and be provided with button switch 5 and button cell box 4, also be provided with sliding rheostat 7, the photoresistor 6 of light sensor on support 2. Because of the beautiful and generous shape, it can be used as decorative sunglasses and sunglasses.

[0012] Such as figure 2 Shown is the chip structure diagram of the light-controlled liquid crystal glasses, the surface is a glass lens 8, and the interlayer is an indium tin oxide 9 to form electrodes X, Y, which are added to the liquid crystal layer 10 in the middle. When the current passing through it is greater than At 0.1mA, the liquid crystal is no longer transparent and bec...

Abstract

The invention discloses light-controlled liquid crystal eyeglasses, which comprises liquid crystal lenses (1) and a bracket (2) for fixing the lenses, wherein a control circuit is connected with the liquid crystal lenses and is connected in series with a power supply, a switch (5), a photo-resistor (6) and a sliding variable resistor (7); and one end of variable resistor is connected with one pole of each liquid crystal lens, and the other end of the variable resistor is connected with the other pole of the liquid crystal lens through a crystal diode (11). The light-controlled liquid crystal eyeglasses can automatically shade bright light to protect eyes of a user, can be taken as an eye protection device in aspects of electric welding, smelting, firing, military and the like, have low cost and are easy to make.
