The present invention relates to an adjusting device, in particular an electrochromic light-filter film (color changeable display of electrical reactions), such as thin films of electrical devices, suspended particle devices, liquid crystal oscillation devices dispersed in polymers, and the like. ) Is applied to the light-transmitting structure to prevent strong light from being irradiated and at the same time, it is a glass contrast adjustment device that blocks the sun.

In general, it covers the sunlight of the car glass or the insulation is mostly sun shade, curtains, insulation paper, etc. Mostly installed in the windshield of the car, the window glass on both sides, the glass or the rear glass of the car to cover the sunlight or heat insulation To reach the effect.

However, sunscreen curtains affect the visibility of the car and cannot be mounted on the windshield of the car, and sunscreens affect the driver's eyesight while driving, so be very careful to check the vehicles and road conditions from behind. The range of size and position can be adjusted. In addition, the use of conventional coated or colored insulating paper prevents the driver from covering sunlight or adjusting the thermal insulation due to the fixed contrast.

The main purpose of the present invention is to automatically or manually control the change of contrast with a light filtration thin film using an electrochromic material (electrochromic device) that changes color by electric reaction, thereby providing intense light irradiation and It is to provide a glass contrast adjustment device that forms an operating state that filters light to prevent daylight crossover.

The above-mentioned object includes a light filtration thin film for changing colors by an electric reaction, a light detector, and a control device, and the light filtration thin film for changing colors by the electric reaction is installed on a windshield of a vehicle, and The corresponding light intensity change is generated by applying a light beam, which is connected to a light filtration thin film that changes color by an electrical reaction, and is used to detect light splitting on the light filtration thin film that changes color by this electrical reaction. Outputs a signal corresponding to the detected light intensity, and the control unit is connected to a light filtration membrane that changes color by light response and electrical response to receive a signal from the light response, and the intensity of the signal It judges whether or not the signal is exceeded and emits a control signal when the strength of the received signal exceeds the predetermined value. It is sent to the power supply which is electrically connected to the light filtration thin film which changes color by the response and the electric reaction, and this power supply is applied to the light filtration thin film which changes the color by the electric reaction and displays the color by changing the color by the electric reaction. A glass contrast adjustment device is characterized by generating a change in contrast.

By using the light filter thin film to change color by electric reaction according to the present invention described above, the operating state of contrast adjustment is reached to improve the shortcomings of the conventional sun shade or heat insulation device and to prevent the strong light irradiation and at the same time It has a moderate blocking effect according to one crossing.

As shown in FIG. 1, the present invention is installed on the windshield of the vehicle, and includes a light sensitive film 10, a control device 11, and a light filtration thin film 12 (color film of an electric device, floating) that displays color by electric reaction. Particle devices, liquid crystal oscillation devices dispersed in a polymer, and the like.

The light filtering thin film 12, which displays colors by changing the color of the electric reaction, is formed of a colorless color generating material that controls the transmission of light through a change in the arrangement of floating particles in the material, thereby changing the intensity.

The light receiver 10 is connected to the light filtration thin film 12 for changing colors by an electric reaction, and thus detects the intensity of the light beam shining on the light filtration thin film 12 for changing the color by an electric reaction. By adjusting the contrast of the light filtration thin film 12, which transmits a signal corresponding to the light intensity and changes the color by an electrical reaction, it is possible to change the step type according to the intensity of the light, and the The installation location is chosen above the vehicle back miller, above the windshield or under the window glass on both sides.

The control device 11 is installed so as to be connected to the light sensitizer 10 and the light filtration thin film 12 which displays the color by changing the electrical reaction, thereby receiving the output signal of the light sensitizer 10 and the intensity of the signal The control device 11 transmits the control signal to the light filter thin film 12 that changes the color by electric reaction with the light-sensitive device 10 when the received signal intensity exceeds the predetermined value. A voltage is applied to the light filtration thin film 12 which is sent to an electrically connected power source and the power is changed in color by an electric reaction, and a user manually operates the control device 11 to change the color by an electric reaction to display the color. The intensity is adjusted by using the characteristic of the color of the light filtering thin film 12 which is applied to the light filtering thin film 12 and the color is changed by this electric reaction, and the control device 11 is transparent. Adopted the design of the wiring will be installed under the car windshield or the top apchang us.

The so-called `` Electrochromic '' refers to the process of changing the color-changing material from the original transparent colorless state to the colored state using voltage difference.If the direction of voltage is reversed, it changes from colored state to colorless state. do.

In other words, when the light receiver 10 detects that there is a light beam, it sends a signal corresponding to the light intensity to the control device 11, and if the control device 11 determines that the light intensity does not exceed a predetermined value. Since the light is not applied to the light filtering thin film 12 which changes color by electric reaction and displays the natural state without changing the contrast of the light filtering thin film 12 which changes color by this electric reaction, the color is changed by electric reaction. The light filtration thin film 12, which is changed to display, does not switch to the brightness change mode.

On the contrary, when the light receiver 10 detects the presence of the light beam, it sends a signal corresponding to the light intensity to the control device 11, and if the control device 11 determines that the light intensity exceeds the predetermined value, the control is performed. The device 11 sends a control signal to a power supply (not shown in the drawing) electrically connected to the light filtration thin film 12 which displays the color change by the electrical reaction with the light-sensitizer 10 and changes the color by the electrical reaction. It is applied to the light filtration thin film 12 to be displayed, and this electric reaction changes the color to generate a change in the arrangement between the floating particles in the light filtration thin film 12 to be displayed.

When the arrangement of the floating particles changes, the light filtering thin film 12 which changes color by displaying an electric reaction is generated, and the light is irradiated to pass through the light filtering thin film 12 which changes the color by displaying an electric reaction. The filter can be filtered to produce a continuous, stepless change within a short period of time so that the light-filtering membrane 12, which changes color by an electrical reaction, automatically filters out strong light or allows the operator to manually operate the light beam. This can be adjusted according to the driver's demand, which effectively prevents dazzling phenomenon.

Therefore, by using the light filter thin film 12 to change the color by the electric reaction to reach the operating state of the contrast adjustment and improve the defects of the conventional sun screen or heat isolation device to prevent the situation to be exposed to sunlight and strong light Ensure safety and comfort when driving.

As illustrated in FIGS. 1,2 and 7, a switch device SW1 is installed between the light filtering thin film 12 and the control device 11 that change colors by electric reaction, and the driver himself switches the switch device ( Switch the switch SW1) to turn on or off the automatic light filtration of the light filtration membrane 12, which changes color by electrical reaction, and if the switch device SW1 is turned off, the driver has at least one rotation. Through the button 141, the light filtering thin film 12 for changing the color by the electric reaction can be operated manually.

The light filtration thin film 12 is arranged in a layered manner in a rod-shaped manner to be applied to the entire windshield (see FIGS. 2 and 5).

4. When the scale 1141 corresponds to F1, the light filtration thin film 12 (i.e., the diagonal area), which changes colors by displaying an electric reaction, replaces the original opaque sunscreen of the car after changing color (Fig. 2). , 6).
