[0033] Figure 1 Front structure schematic diagram of a mirror provided by an embodiment of the present utility model, Figure 2 AlongFigure 1 Schematic cross-sectional structure diagram along A-A. Refer to Figure 1 and Figure 2 This mirror includes:

[0034] An imaging area 110, which can display a reflected image;

[0035] A mirror display glass 210, which is at least located in the imaging area 110. The mirror display glass 210 has light-transmitting and reflecting properties;

[0036] An LED module 220, which is located on the back of the mirror display glass 210. The LED module 220 can emit light and generate heat;

[0037] A monitoring controller 230, which is electrically connected to the LED module 220. The monitoring controller 230 can monitor the mirror surface temperature, ambient temperature, and illuminance of the mirror, and send control instructions to the LED module 220.

[0038] Among them, the imaging area 110 is the main area of the mirror. When a user uses this mirror, the environmental image or portrait to be reflected is presented through the imaging area 110.

[0039] The fact that the mirror display glass 210 has light-transmitting and reflecting properties means that the mirror display glass can transmit light and reflect light. Specifically, it is a high-tech multifunctional display material with special optical properties. It is mainly made of high-quality glass materials (such as float glass or ultra-clear glass), and a special metal or dielectric thin film, such as aluminum, chromium, titanium, titanium oxide, etc., is coated on the glass surface. The thickness and refractive index of these thin films are different, which can affect the reflecting and light-transmitting properties of the mirror display glass 210. Exemplarily, the light transmittance of the light-transmitting and reflecting mirror display glass 210 ranges from 10% to 80%, and the reflectance is about 70%. Preferably, the light transmittance is 30% and the reflectance is 70%. Such a setting can not only meet the imaging function of the mirror but also provide illumination through the light of the LED module 220. Usually, in Figure 2 the right side of the mirror display glass 210 (i.e., the mirror) is the user side, which is also the front of the mirror display glass 210 (i.e., the mirror), and the left side of the mirror display glass 210 is the back.

[0040] The LED module 220 includes LEDs (Light Emitting Diodes). During operation, the LEDs generate heat, which is an inherent property of the LEDs. In the prior art, a heat sink is usually provided to dissipate heat from the LED module to prevent the temperature of the LEDs from being too high and causing light decay. In the embodiments of the present invention, the LED module 220 is disposed on the back surface of the mirror display glass 210. By utilizing the heat generation performance of the LEDs, the mirror display glass 210 can be heated. This arrangement can not only prevent the mirror from fogging or improve the defogging effect of the mirror, but also utilize the heat absorbed by the mirror display glass 210 during the defogging process to dissipate the heat generated by the LED module 220.

[0041] The monitoring and control controller 230 has monitoring and control functions. Exemplarily, the monitoring and control controller 230 includes a first temperature sensor for monitoring the mirror surface temperature, a second temperature sensor for monitoring the ambient temperature, and an illuminance sensor for monitoring the ambient illuminance. The first temperature sensor can be disposed on the mirror display glass 210, the second temperature sensor can be disposed on the housing 250 of the mirror, and the illuminance sensor can be disposed on the outer surface of the housing 250 of the mirror or the front surface of the mirror display glass 210. If the difference between the monitored mirror surface temperature and the ambient temperature is large, for example, due to reasons such as taking a bath, the ambient temperature rises rapidly within a short period of time, then the monitoring and control controller 230 activates the heating function of the LED module 220. Specifically, the heating intensity of the mirror display glass 210 can be controlled by controlling the magnitude of the current, thereby preventing the mirror surface from fogging or starting defogging. If the monitored ambient illuminance is dim, then the monitoring and control controller 230 activates the lighting function of the LED module 220. Specifically, the brightness can be adjusted by controlling the magnitude of the current, thereby replacing the front mirror lamp.

[0042] In the embodiments of the present invention, by providing the mirror display glass 210, the LED module 220, and the monitoring and control controller 230 in the mirror, on the one hand, the heat generation performance of the LED module 220 can be utilized to heat the mirror display glass 210, thereby achieving the function of preventing the mirror from fogging or improving the defogging effect of the mirror; on the other hand, by utilizing the characteristic that the mirror display glass 210 has a certain light transmittance, the lighting performance of the LED module 220 can be utilized to illuminate the mirror. While replacing the front mirror lamp, it does not affect the area of the imaging region; on the still other hand, when the mirror has the need to perform defogging and lighting simultaneously, the LED module 220 dissipates heat when it is lit, and this dissipated heat can also be used for mirror defogging, thereby helping to reduce the power consumption of the mirror.

[0043] Figure 3 This is a schematic cross-sectional structure diagram of another mirror provided by the embodiments of the present invention. Refer to Figure 3, based on the above embodiments, optionally, the mirror further includes a transparent heating film 240, which is located between the LED module 220 and the mirror display glass 210; and the transparent heating film 240 is electrically connected to the monitoring controller 230 and receives the control of the monitoring controller 230. Exemplarily, the transparent heating film 240 includes an indium tin oxide film (ITO film).

[0044] Among them, the transparent heating film 240 can generate heat by applying a voltage, and the generated heat can heat the mirror display glass 210, playing an auxiliary role in the heating function of the LED module 220, shortening the heating and defogging time of the mirror display glass 210, and further improving the defogging effect.

[0045] Continue to refer to Figure 3 , based on the above embodiments, optionally, the monitoring controller 230 is located on the back of the LED module 220; the transparent heating film 240 and the monitoring controller 230 are electrically connected through a flexible circuit board 260. Among them, the flexible printed circuit (FPC) 260 can be folded, and the setting method is flexible, which is beneficial to the connection between the transparent heating film 240 and the monitoring controller 230 and does not occupy the space of the mirror.

[0046] Continue to refer to Figure 2 and Figure 3 , in one embodiment, optionally, the LED module 220 includes: a Mini LED light board or a Micro LED light board. Among them, Mini LED and Micro LED are two different sizes of light-emitting diodes. The long side size of the chip of Mini LED is usually between 100 and 300 micrometers (μm), and its pixel center pitch is 0.3 - 1.5 millimeters (mm), belonging to the category of sub-millimeter light-emitting diodes, which can provide uniform and efficient backlight through a dense LED array, improving the display effect. The size of Micro LED is smaller, and its chip size is usually between 1 and 10 micrometers (μm), much smaller than Mini LED. It can achieve a higher pixel density and a finer display effect, and at the same time has the self-luminous characteristic and does not require a backlight system.

Figure 5 This is a schematic cross-sectional structure diagram of another mirror provided by an embodiment of the present invention. Refer to Figure 4 and Figure 5, in another embodiment of the present utility model, optionally, the LED module 220 includes an LED film screen. Exemplarily, the LED film screen is formed by arranging LEDs between two layers of polyethylene terephthalate films (PET films), thereby forming a transparent LED module. The LED film screen has the characteristics of being thin and light, can be bent and cut arbitrarily, so as to adapt to mounting surfaces of different shapes and sizes, and the mounting operation is simple and easy to implement.

[0048] Continue to refer to Figure 4 and Figure 5 , wherein, Figure 5 Compared with Figure 4 , the difference is that Figure 5 In the embodiment shown, a transparent heating film 240 is further provided between the LED film screen and the mirror display glass 210.

Refer to Figure 6 and Figure 7 , on the basis of the above embodiments, optionally, the mirror further includes: a display module 130, the display module 130 is located within the imaging area 110, and the size of the display module 130 is smaller than the size of the imaging area 110; the display module 130 can display information. Among them, the display module 130 can perform image display according to image data, and the display information can be at least one of date, time, temperature, weather, reminder information, etc. Exemplarily, the display module 130 can be set at positions such as the upper left corner, the middle of the top, the upper right corner, the lower left corner, the middle of the bottom, and the lower right corner of the imaging area 110, and can be set according to needs in actual applications.

[0050] Optionally, the display module 130 can be electrically connected to the monitoring controller to obtain display data from the monitoring controller. In other embodiments, the display module 130 can also be provided with an independent display controller, which is not limited in the present utility model.

[0051] On the basis of the above embodiments, there are various ways to set the display module 130. In one embodiment, optionally, different from the LED module, the display module 130 includes at least one of a liquid crystal display module 130 and an organic light emitting diode display module 130.

[0052] In another embodiment, optionally, since the mirror display glass has a light-transmitting function, a part of the area in the LED module is reused as the display module 130, that is, most of the area of the LED module is used for heating to perform the defogging function of the mirror, and a small part of the area is used for information display. The heat generated during the display of this small part of the area can also be used to defog the mirror.

[0053] Continue to refer to Figure 6 and Figure 7 , based on the above embodiments, optionally, the mirror further includes: an illumination module 120, which is located outside the imaging area 110; and the illumination module 120 is electrically connected to the monitoring controller 230 and receives the control of the monitoring controller 230. Among them, the illumination module 120 can provide light when the ambient illuminance is low, providing the function of a front mirror light.

[0054] Optionally, the illumination module 120 is disposed on the left, top, and right sides of the imaging area 110, which is more in line with the user's usage habits and improves the user's usage experience.

[0055] Based on the above embodiments, optionally, there are various ways to set the illumination module 120.

Among them, the part of the LED module 220 corresponding to the illumination module 120 has a higher brightness when illumination is required, and can perform the conventional mirror imaging function when illumination is not required.

[0056] In another embodiment, optionally, the LED module 220 and the illumination module 120 are independently arranged.
