[0062] In the embodiments provided in the present application, the reflective layer 40 faces the transparent conductive layer 20, the reflective layer 40 is spaced apart from the transparent conductive layer 20, the transparent conductive layer 20 can be connected to the positive electrode of the power supply, and the reflective layer 40 can be electrically connected to the negative electrode of the power supply. The transparent conductive layer 20 connected to the positive electrode of the power supply and the reflective layer 40 connected to the negative electrode of the power supply can form an electric field.

[0063] The sealing adhesive 70 is connected between the first transparent substrate 10 and the second transparent substrate 30, and surrounds the transparent conductive layer 20 and the reflective layer 40 to form a cavity. The cavity is used to accommodate the light-adjusting composition 50, and the light-adjusting composition is used to adjust the reflectivity of incident light.

[0064] The sealing adhesive 70 includes glue and filling particles. The glue can be thermosetting glue, and the sealing adhesive 70 can also be light-curing or heat-curing glue. Specifically, the glue includes but is not limited to phenolic, epoxy, polyurethane, unsaturated polyester, heterocyclic polymer, unsaturated polyvinyl, polyacrylic acid, epoxy-acrylic acid, and polyurethane-acrylic acid. The dielectric constant of the glue can be 2 to 4.

[0065] The dielectric constant of the filling particles is greater than or equal to 20, which can improve the breakdown voltage of the electric field formed by the reflective layer 40 and the transparent conductive layer 20, thereby improving the electrochemical stability of the light-adjusting composition under the action of the electric field, further improving the reflection reliability of the reflector, and prolonging the service life of the reflector.

For details, see the following table. In the table, when the sealing glue is doped with filling particles of a dielectric constant of 26, a voltage of 7V is needed between the transparent conductive layer and the reflective layer to break down. When the sealing glue is doped with filling particles of a dielectric constant of 50, a voltage of 12V is needed between the transparent conductive layer and the reflective layer to break down. When the sealing glue is doped with filling particles of a dielectric constant of 1.56, only a voltage of 3V is needed between the transparent conductive layer and the reflective layer to break down.

[0068] Dielectric constant of the filler particles Voltage resistance performance Example 1 26 7V breakdown failure Example 2 50 12V breakdown failure Comparative Example 1 1.56 3V breakdown failure

[0069] The shape of the filling particles can be any one of a cuboid, a cube, a sphere or a cylinder. In the sealing glue 70, the shapes of the filling particles can be the same, or different shapes of the filling particles can exist in the sealing glue 70. The filling particles with regular shapes and uniform sizes can be used as supports to effectively ensure the uniform thickness of the sealing glue, thereby ensuring the uniform gap between the first transparent substrate and the second transparent substrate, and ensuring the stable and uniform electric field and reflectivity of the positive and negative electrode plates.

[0070] In the embodiments provided in the present application, when the filling particles are spheres, the size of the filling particles is 30-300 μm. The uniform size of the filling particles in the glue can make the sealing glue 70 tend to be flat as a whole, and improve the stability of the sealing glue 70 in connecting the first transparent substrate 10 and the second transparent substrate 30.

[0071] In the embodiments provided in the present application, in one possible implementation, the transparent conductive layer 20 completely covers the second surface 12, the transition layer 60 completely covers the third surface 31, the reflective layer 40 completely covers the transition layer 60, and the sealing glue 70 is connected between the transparent conductive layer 20 and the reflective layer 40 and surrounds the cavity.

[0072] In the embodiments provided in the present application, please refer to Figure 3The surface of the transparent conductive layer 20 facing the first transparent substrate comprises a contact area 21 in contact with the second surface and a recessed area 22 recessed away from the second surface 12, the recessed area 22 surrounds the contact area 21, the recessed area 22 is spaced apart from the second surface 12, and a decorative layer 80 is arranged between the recessed area 22 and the second surface 12, the reflectivity of the decorative layer 80 is greater than or equal to 50%. The reflectivity of the decorative layer 80 can have an error of 10%, and in actual application, the reflectivity of the decorative layer 80 can be greater than or equal to 45%. On the one hand, the decorative layer 80 can improve the overall aesthetics of the reflective device, and on the other hand, the decorative layer 80 can reduce the escape of light incident on the light-adjusting composition 50 from the sealing gel 70.

[0074] In the embodiments provided in the present application, the light-adjusting composition 50 is in contact with the transparent conductive layer 20 and the reflective layer 40, in other words, if the first transparent substrate 10 and the second transparent substrate 30 are arranged in a top-down manner, the light-adjusting composition 50 is arranged on the third surface 31 of the second transparent substrate 30, and the light-adjusting composition 50 can support the first transparent substrate 10, thereby improving the stability of the overall structure of the reflective device.

[0075] The light-adjusting composition 50 has a cathode active substance and an anode active substance, and under the action of an electric field, the light-adjusting composition 50 can undergo an electrochemical oxidation-reduction reaction, so that the molecular structure in the light-adjusting composition 50 changes, thereby improving the absorption of incident light by the light-adjusting composition 50 and reducing the reflectivity of the reflective device. For example, under the action of an electric field, the light-adjusting composition 50 can change the absorption of incident light, and if the light-adjusting composition 50 increases the ability to absorb light under the action of an electric field, the reflectivity of the reflective device can be reduced from more than 60% to less than 15%. It should be noted that when the reflectivity of the reflective device is adjusted, the reflectivity of the reflective device can be controlled by adjusting the intensity of the electric field.

[0076] In the embodiments provided in the present application, the reflective device further comprises a transition layer 60, the transition layer 60 is arranged between the reflective layer 40 and the third surface 31, and the transition layer 60 comprises at least one of SiO (silicon monoxide), TiO (indium tin oxide), Nb2O5 (diniobium pentoxide) and Al2O3 (aluminum trioxide). It should be noted that the second transparent substrate 30 comprises one of glass, acrylic and polyvinyl chloride, and the reflective layer 40 comprises one of silver, silver alloy, aluminum, aluminum alloy, chromium and chromium alloy. If the reflective layer 40 is directly arranged on the second transparent substrate 30, the connection between the reflective layer 40 and the second transparent substrate 30 is unstable. The transition layer 60 comprises at least one of SiO, TiO, Nb2O5 and Al2O3, the transition layer 60 can be well attached to the second transparent substrate 30, and the reflective layer 40 can also be well attached to the transition layer 60. By arranging the transition layer 60 on the third surface 31 of the second transparent substrate 30 and then arranging the reflective layer 40 on the transition layer 60, the reflective layer 40 can be more stably arranged on the second transparent substrate 30. The thickness of the transition layer 60 can be 1 nm-300 nm, and an error of 10% is allowed in the process of forming the transition layer 60.

Specifically, the first electrode sheet 90 is connected with the positive electrode of the external power supply, and the second electrode sheet 100 is connected with the negative electrode of the external power supply, so that the transparent conductive layer 20 and the reflective layer 40 form an electric field.
