BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to discoloration and dimming devices of transparent plates such as glass and synthetic resins, and in particular, to control the discoloration and light transmittance of high-functional plates in accordance with the diversification of the design and comfort due to the expansion of the clock. In addition, due to the discoloration and dimming function, it improves the fascination according to the user's demand, improves the comfort, reduces the temperature rise due to the effect of reducing infrared rays and ultraviolet rays, prevents the soot of the human skin, and triple structure. This is to bring about the increase in strength of the transparent plate.

In general, the transparent sheet material of the same type as the present invention, particularly the glass sheet material is intended to bring about an increase in the strength of the transparent plate due to the L group of the building.

In general, the demand is increasing according to the diversification of the building costume or design of the transparent plate material of the present invention, in particular, the glass plate material, conventionally, heat ray reflection glass plate, photochromic glass, liquid crystal The attached glass plate material, the current-type dimming glass plate material using an electrolytic layer, etc. are emerging. However, each of the conventional products of the above examples has advantages and disadvantages as described below.

[Photosensitive Glass Plate]

The photosensitive glass sheet is a change in light absorption due to a change in the reversible molecular structure caused by light between the chemical species A and B, and is represented by the following equation.

Dimming glass plate material using the photosensitive action has a system in which the photosensitive material is dispersed in the glass plate material and a system in which the photosensitive material is laminated on two glass plate materials.

In the former case, silver halide agglomerates are dispersed in a glass plate, and are practically used in sunglasses and the like. This glass has excellent durability but a slow response speed.

In the latter case, the organic photosensitive material is made of a laminate of a film and a glass plate material doped with a polymer matrix. The biggest problem with this organic photosensitive material is the durability and the like, the repeated life of the color fading and the improvement of the heat resistance.

The characteristic of such a photosensitive glass plate is that the color intensity changes according to the intensity of light hv, as indicated by the above formula (1), and consequently, it is pointed out that a color intensity cannot be controlled.

[Glass Plate Material with Liquid Crystal]

Liquid crystal display devices that have been put to practical use in electronic devices and the like need to precisely maintain a glass sheet material spacing of several micrometers, so that large area is difficult. For this reason, the film | membrane which disperse | distributed the microcapsular nematic liquid crystal in the polymer matrix is used.

NCAP devices (Nematic Curvilirear Align-Phase Devices) are being developed. When the electric field is applied to the polymer matrix, the liquid crystal is oriented and transmits light. When the electric field is interrupted, light is scattered and becomes cloudy, and the turbidity is controlled by the intensity of the electric field.

The disadvantage of this device is that it does not take advantage of changes due to absorption of light, so the change in transmittance is small and simply "invisible".

In other words, the contrast cannot be changed.

[Currently Dimmed Glass Plate Using Electrolyte Layer]

This method is a phenomenon in which chemical species A and B are reversibly changed by the electrochemical redox reaction and the light absorption on the electrode surface is changed.

The tungsten oxide ammeter shown in FIG. 7 shows a conceptual diagram of a current equation (EC) reaction of tungsten oxide (WO ₃ ) currently being developed.

A tungsten oxide thin film 32 (0.4-1.0 μm) formed on the transparent conductive film 31, an electrolyte layer 33 having a lithium ion conductivity and no electronic conductivity, and a counter electrode 34.

As if it had a colorless and transparent thin film and applied voltage to the opposite electrode correctly, tungsten front (Mx WO ₃ ) because electrons were injected more than transparent electrodes and lithium ions (Li ⁺ ) were injected into the tungsten oxide thin film to reduce tungsten oxide It becomes blue.

35 is a glass substrate.

Then, when the voltage is reversed and the tungsten oxide thin film layer is correctly added to the counter electrode, the tungsten front returns to the colorless and transparent tungsten oxide thin film. At this time, on the counter electrode, the electrochemical oxidation reaction is reversed upon tungsten oxide reduction (coloring), and the electrochemical reduction reaction is produced upon tungsten oxide oxidation (coloring). The characteristics of the current type dimming glass plate material using this electrolytic layer are as follows.

[Advantages]

Ⓐ Easy to large area.

Ⓑ There is memory. In order to perform a coloring reaction, an electrochemical reaction is required. Therefore, unless the current flows from the outside, the color remains intact.

Ⓒ Good visibility.

Ⓓ Clear coloring, multicolor display.

[Disadvantages]

Ⓐ Slow response speed (takes about 1 minute response time at 45cm × 60cm)

Ⓑ The return life is about 10 ⁷ times.

Ⓒ Poor heat resistance (It will be damaged when it is over 70 ℃ -90 ℃)

Ⓓ Mass production is difficult due to the complicated structure and high cost.

Ⓔ In case of damage, use liquids and components that are harmful to human body.

Ⓕ It is difficult to discolor various colors except designated color.

Because of these drawbacks, the display element is limited in the scope of application, and it is used as a display element in which the coloration operation is less repeated and the response speed is not a problem.

In addition, it is used where the above-mentioned disadvantage does not become a problem relatively large area light-shielding glass plate material.

Moreover, this has the feature that "the transmittance of light changes arbitrarily and continuously" compared with the above-mentioned photosensitive glass plate material and the light control glass plate material using a liquid crystal.

The present invention has almost no response delay time due to the large-area, discoloration and dimming functions, low cost, and instantaneous operation (speed of light), which have not been solved by a technology similar to the conventional invention, and various color effects can be obtained. In addition, it is possible to finely adjust the state of discoloration and dimming, and has the advantage of high heat resistance (melting point of the glass plate material) and operating at high temperature, and to provide a transparent plate material that does not have a harmful solution in case of breakage. It can be used semi-permanently using the reflection principle of the plate itself.

When described in detail by the accompanying drawings as follows.

In other words, in the molten state of the plate material, the reflective particles 1 of the same material as the plate material is mixed and solidified, so that the transparent plate material at the center of the transparent plate material 2A before and at the rear of the transparent plate material 2A in which the reflective particles 1 are distributed therein. Upper and side reflectors (e.g., mirrors) (3) (4) on the upper and left and right sides of the transparent plate body 2, each of which is bonded to each of the front and rear transparent plate materials 2B and 2C having a higher density than (2A). ) And attach each of them and wrap the fixing frame (5) on the lower edge of the upper and side reflectors (3) and the transparent plate body (2), and discolor in the fixing frame (5) directly below the transparent plate body (2). And the dimming control device 6 are interpolated. In addition, by forming the light dimming state display unit 7 in which the reflective particles 1 are densely formed at one side of the main body 2 of the transparent plate, the discoloration and dimming control are poor, so that the discoloration and dimming state can be easily identified. Do it.

In the above, the discoloration and dimming control device 6 is fixed to the light source body (for example, lighting) 9 on the central axis (8), and to install the spectroscopic lens 10 directly above the light source body (9) Both sides of the spectroscopic lens 10 are fixed to the upper sides of the reflecting tube 11, and a color-changing tube 12 having several colors separated on an outer circumferential surface of the reflecting tube 11 is installed to center the one end of the color changing tube 12. A dimming controller with a variable resistor 14 'built into the central shaft 8 on one side of the color fading controller 13 to rotate the color fading controller 13 inserted into one side of the shaft 8 to rotate. 14) is installed by rotating material.

In the above, the power supply terminal (+) (-) is connected to the dimming controller 14 and the light source body 9, respectively, in the drawings, 15 and 16 are bearings, and S is a spacer.

On the other hand, the discoloration and dimming apparatus of the transparent plate member shown in Fig. 6 is another embodiment for applying the curved surface to the transparent plate member, the same reference numerals are used for the same parts in the first embodiment. The discoloration and dimming control device 6 is placed directly on the center of the curved transparent plate body 2 (this transparent plate is also triple bonded as in the first embodiment), that is, the symmetrical center of the transparent plate body 2. And the upper and lower reflectors 18 and 19 are installed at a predetermined angle so that the light rays are refracted and reflected, so that the operation and effect of the first embodiment described later are the same.

Effects of the present invention configured as described above are as follows. As shown in FIG. 4, the color change cylinder 12 is rotated as the color change controller 13 so that the blue portion of the color change cylinder 12 is positioned directly above the spectroscopic lens 10, and the power is applied to the light source body 9. When the light rays from the light beams are emitted, the arbitrary reflection particles (a) receive the upper beam of the spectral lens (10) in the transparent state and cause blue diffuse reflection, and the arbitrary reflection particles (b) are at the center of the optical axis. Blue diffuse reflection occurs.

In addition, the arbitrary reflecting particles (c) are also subjected to refraction of the lower beam of the spectroscopic lens 10 by refraction and also blue diffuse reflection, and the arbitrary reflecting particles (d) by the upper reflecting plate (3) as a light beam that has completed the diffuse reflection The returned light causes the light to be amplified by this return action.

In the above, the spectroscopic lens 10 serves to cause pulsation of the light beam to evenly adjust the overall dimming and discoloring functions.

In addition, since the transparent plate member 2A incorporating the reflective particles 1 is bonded to the transparent plate member 2B and 2C having high density on the front and rear surfaces thereof, the light source body 9 incident through the spectroscopic lens 10 is applied. Since the ray of light proceeds while causing refraction due to total reflection, when the blue portion of the color change cylinder 12 is arbitrarily adjusted and positioned directly above the spectroscopic lens 10 as in the above example, the transparent plate body 2 is blue and transparent. It will be turned into a plate.

For example, when changing to a reddish transparent plate, the color fading controller 13 may be adjusted so that the red portion of the color fading cylinder 12 is positioned directly above the spectroscopic lens 10.

In the present invention, since the color change due to the light emitted from the light source body 9, the response delay time is the same as the speed of light.

On the other hand, if the brightness control of the light source body 9 is adjusted by adjusting the dimming controller 14, the diffuse reflectance of the reflective particles 1 is increased or decreased to scatter the light to pass through, as shown in FIG. 5A. ), The brightness of the light beam a caused by the reflective particles 1 is less than that of the external light beam b that tries to pass through the transparent plate body 2. The illuminance of the surface passing through) is Lux = a + b (a = 1, b is 3) and Lux = 1 + 3 = 4.

Therefore, since the diffuse reflectance by the reflective particles 1 is small, in this case, part of the external light b is blocked, and part of the external light b is passed through as it is, so that the object on the outside can be identified.

In addition, as shown in (u) of FIG. 5, when the light intensity of the light source body 9 is largely adjusted by adjusting the light intensity of the light source body 9, the light beam a ′ caused by the reflective particles 1 is compared to the external light b ′. ), The intensity of light is increased to some extent, and the illuminance received by the surface passing through the transparent plate body 2 becomes Lux = 2 + 3 = 6 (assuming a '= 2 and b' = 3).

Therefore, since the diffuse reflectance by the reflective particles 1 is large, the outside ray is blocked by the diffuse reflection of the reflective particles, so that the inside of the outside is hardly discerned.

As shown in this example, it can be seen that the illuminance (Lux) of the place passing through the transparent plate body 2 of FIG. 5b is relatively larger than that of FIG. 5a, and thus, the light source body 9 as the dimming controller 14 is relatively large. By controlling the luminous intensity of the transmittance through the transparent plate will be able to control arbitrarily.

As described above, the present invention provides a transparent plate material using a discoloration and dimming control device, which can increase the area of the transparent plate material, and before the central transparent plate material in which reflective particles such as high density of the same material are distributed, By bonding the transparent plate material having a higher density than the transparent plate material on the rear side in three times, when the transparent plate body receives heat, it has the same heat resistance as the melting temperature of the transparent plate material. It is possible to perform the function of discoloration and dimming of transparent plate, resulting in low cost, finely adjusting various discoloration effect and dimming state by discoloration tube, and have a long service life. .
