Description

Technical Field

[0001] This utility model relates to the field of bathroom technology, and in particular to a double-sided light-emitting mirror structure, a folding mirror, and a bathroom cabinet. Background Technology

[0002] With the increasingly fast pace of modern life and work, users are constantly raising their demands for the functionality and efficiency of bathroom spaces. Bathroom vanities not only need to meet basic storage needs, but are also increasingly being used as a place for makeup application. Therefore, the lighting effect in front of the bathroom mirror has become crucial.

[0003] If the light does not reach the user's face after the mirror door is opened, the user needs to close the mirror door again before the light can reach their face, which undoubtedly brings a bad experience to the user.

[0004] Currently, common bathroom mirror lighting solutions on the market mainly involve installing single-sided luminous strips along the edge of the mirror or frame. These strips provide basic illumination for users applying makeup when the mirror door is closed. However, when users open the mirror door to use the storage space inside, the light cannot effectively illuminate their face, forcing them to frequently close the door to obtain clear lighting. This repeated opening and closing of the mirror door severely disrupts the flow of the makeup process, creating an inconvenient user experience. Utility Model Content

[0005] This invention provides a double-sided light-emitting mirror structure, a folding mirror, and a bathroom cabinet to improve the user's unpleasant experience of frequently opening and closing mirror doors.

[0006] According to one aspect of the present invention, a double-sided light-emitting mirror structure is provided, comprising:

[0007] First border;

[0008] A first mirror and a second mirror are respectively disposed on two opposite sides of the first frame and are both connected to the first frame. The first mirror, the second mirror and the first frame form a first cavity. The first mirror is provided with a first light-transmitting area and the second mirror is provided with a second light-transmitting area. The first light-transmitting area and the second light-transmitting area are disposed opposite to each other.

[0009] A light-emitting component is disposed within the first cavity;

[0010] The light-emitting component includes:

[0011] light source;

[0012] A light guide plate includes an incident light surface and an exit light surface. The light source is located on one side of the incident light surface, and the exit light surface is positioned opposite the first light-transmitting area and the second light-transmitting area. The light guide plate contains a plurality of scattering particles. The distribution density of the scattering particles gradually increases along the direction from near the light source to away from the light source.

[0013] Optionally, the light-emitting surface includes a first light-emitting surface and a second light-emitting surface disposed opposite to each other;

[0014] The light guide plate also includes a reflective surface opposite to the light incident surface;

[0016] The first light-emitting surface is disposed opposite to the first light-transmitting area, and the second light-emitting surface is disposed opposite to the second light-transmitting area.

[0022] Along the optical axis of the light source, the width of the second light-transmitting area is smaller than the width of the second light-emitting surface.

[0023] Optionally, the light-emitting component further includes a packaging material covering the outside of the light guide plate and the light source, wherein the packaging material is a light-transmitting material.

[0024] According to another aspect of the present invention, a folding mirror is provided, comprising:

[0025] Second border;

[0026] The third mirror and the fourth mirror are respectively disposed on two opposite sides of the second frame and are both connected to the second frame;

[0027] In any of the double-sided light-emitting mirror structures described in the first aspect, the first frame and the second frame of the double-sided light-emitting mirror structure are hinged together.

[0032] The double-sided luminous mirror structure, folding mirror, and bathroom cabinet provided in this embodiment of the invention achieve the effect of simultaneous light emission from both sides by setting a light-emitting component within a first cavity formed by a first mirror, a second mirror, and a first frame, and designing the light source and light guide plate structure of the light-emitting component. Furthermore, the distribution density of scattering particles gradually increases from the near-light source area to the far-light source area, achieving highly uniform illumination. When the double-sided luminous mirror structure is closed as a mirror door, light passes through the first light-transmitting area, providing primary illumination for the outer mirror (i.e., the first mirror). When the double-sided luminous mirror structure is opened as a mirror door, light can also be emitted outward through the second light-transmitting area, providing continuous auxiliary illumination for the inner mirror (i.e., the second mirror). Users can still obtain sufficient light in front of the inner mirror (i.e., the second mirror), avoiding the problem of lighting interruption due to opening the door, improving the unpleasant experience of frequently opening and closing the mirror door, and enhancing ease of use.

Figure 2 This is a partial cross-sectional schematic diagram of a double-sided light-emitting mirror structure provided in an embodiment of the present invention. Figure 3 This is a schematic diagram of the structure of a light-emitting component provided in an embodiment of the present utility model, as shown below. Figures 1-3 As shown, the double-sided light-emitting mirror structure provided in this embodiment of the present invention includes:

[0043] First border 10.

[0044] The first mirror 11 and the second mirror 12 are respectively disposed on two opposite sides of the first frame 10 and are both connected to the first frame 10. The first mirror 11, the second mirror 12 and the first frame 10 form a first cavity 13. The first mirror 11 is provided with a first light-transmitting area 110 and the second mirror 12 is provided with a second light-transmitting area 120. The first light-transmitting area 110 and the second light-transmitting area 120 are disposed opposite to each other.

[0045] The light-emitting component 20 is disposed in the first cavity 13.

[0046] The light-emitting component 20 includes:

[0047] Light source 202.

[0048] The light guide plate 201 includes a light-incident surface 31 and a light-exiting surface 30. The light source 202 is disposed on one side of the light-incident surface 31, and the light-exiting surface 30 is disposed opposite to the first light-transmitting area 110 and the second light-transmitting area 120.

[0049] The light guide plate 201 contains multiple scattering particles 50.

[0050] The distribution density of scattering particles 50 gradually increases along the direction from near to far from the light source 202.

[0051] Specifically, the first frame 10, as the supporting frame of the entire mirror body, can be assembled by screws from multiple metal profiles (for example, four metal strips connected end to end in sequence) to form a rectangular frame, which has good structural stability and corrosion resistance.

[0052] like Figure 1 and Figure 2 As shown, the first mirror 11 is connected to one end of the inner wall of the first frame 10, and the second mirror 12 is connected to the other end of the inner wall of the first frame 10. The first mirror 11 and the second mirror 12 are arranged opposite to each other, that is, the first mirror 11 and the second mirror 12 are respectively pasted on the front and back of the first frame 10. The first mirror 11 and the second mirror 12 are parallel to each other and are firmly attached to the first frame 10. The first mirror 11, the second mirror 12 and the first frame 10 together form a sealed first cavity 13. The first cavity 13 is used to accommodate and protect the internal optical components, prevent moisture and dust from entering, and improve the product's service life.

[0053] The first mirror 11 has a first light-transmitting area 110, and the second mirror 12 has a second light-transmitting area 120. The first light-transmitting area 110 and the second light-transmitting area 120 are arranged opposite to each other to ensure that light can pass through efficiently.

[0054] In some embodiments, the first mirror 11 and the second mirror 12 are both made of transparent glass substrates. The surface of the glass substrate is coated with a reflective layer, and transparent windows are formed in specific areas through a local silvering process as the first light-transmitting area 110 and the second light-transmitting area 120. The remaining areas retain the mirror reflection function, maintain the integrity of the mirror surface, optimize the visual aesthetics, and effectively isolate water vapor, moisture and dust, thereby improving the safety and service life of the product in a high-humidity bathroom environment.

[0055] In some embodiments, the first light-transmitting area 110 and the second light-transmitting area 120 can be elongated through holes respectively opened on the first mirror 11 and the second mirror 12, with a light-transmitting plate (such as a transparent acrylic plate or a frosted acrylic plate) embedded in the through hole. The light-transmitting plate can be selected with different optical properties according to lighting requirements. For example, if high-brightness lighting is required, a transparent acrylic plate can be used, with a light transmittance of over 90%, maximizing the transmission of light source brightness; if a soft, glare-free diffused effect is required, a frosted acrylic plate or a polycarbonate (PC) plate with a frosted surface can be used, making the emitted light more visually comfortable.

[0056] like Figures 1-3 As shown, the light-emitting component 20 is embedded in the first cavity 13, completely eliminating exposed light strips or LED beads, maintaining the integrity of the mirror surface, and achieving concealed lighting.

[0057] Optionally, the thickness of the first cavity 13 is greater than the thickness of the light-emitting component 20 in the direction from the first mirror 11 to the second mirror 12, so as to ensure that the light-emitting component 20 can be installed smoothly and to avoid crushing the first mirror 11 and the second mirror 12.

[0058] The light-emitting component 20 is provided with a light guide plate 201 and a light source 202. The light guide plate 201 is made of a high-transmittance transparent plastic material, such as polymethyl methacrylate (PMMA) or polycarbonate (PC). The above materials have excellent optical properties, with a transmittance of usually over 92% and a refractive index of about 1.49 (such as PMMA), and have good light transmission ability.

[0059] The light source 202 may include a row of LED beads and a printed circuit board (PCB) that carries the LED beads. Multiple LED beads are evenly arranged on the PCB substrate along a straight or arc path to form a linear or strip-shaped light-emitting module. The light source 202 is precisely mounted on one side of the light incident surface 31 of the light guide plate 201 to ensure that the light emitted by the light source 202 can be efficiently incident on the light incident surface 31.

[0060] In some embodiments, the light source 202 is an LED light strip, which includes multiple LED beads and a resistor element for current limiting protection. The above devices are integrated on a printed circuit board (PCB) to form an independently operable light-emitting module.

[0061] The color of LED beads can be characterized by color temperature (CCT), which can be any value between 2700K and 7000K.

[0062] In some embodiments, the LED beads can adopt a multi-color temperature combination design. For example, dual-color temperature LED beads (such as warm white 3000K + cool white 6500K) can be configured, and the color temperature can be infinitely adjusted within the range of 3000K to 6500K by adjusting the ratio of the driving current of the two types of beads; or, RGBW (red, green, blue, white) or multi-channel LEDs can be used to achieve full-color color changing and white light color temperature adjustment functions. This design allows users to freely switch the light color according to different times, environments, or usage needs. The color changing range can be any color temperature between the highest color temperature (such as 7000K) and the lowest color temperature (such as 2700K), enhancing the personalized experience of the product.

[0063] In some embodiments, the color rendering index (CRI) of each LED bead is greater than 90Ra, preferably above 95Ra. A high CRI can reproduce realistic lighting effects, accurately presenting details such as skin tone, makeup color, and clothing texture, avoiding makeup deviations caused by lighting distortion.

[0064] In some embodiments, to achieve high color rendering, LED chips employ high-quality phosphor formulations (such as nitride red phosphor + silicate green phosphor) and optimize chip packaging processes to improve spectral coverage and continuity.

[0065] The light guide plate 201 has a light incident surface 31, through which the light beam emitted by the light source 202 enters.

[0066] The light guide plate 201 also has a light-emitting surface 30. The light-emitting component 20 is precisely fixed during assembly so that the light-emitting surface 30 of the light guide plate 201 is directly facing the first light-transmitting area 110 on the first mirror 11 and the second light-transmitting area 120 on the second mirror 12.

[0067] In this embodiment, the light emitted by the light source 202 is uniformly distributed inside the light guide plate 201 and then emitted from the light-emitting surface 30, directly passing through the corresponding first light-transmitting area 110 and second light-transmitting area 120 to emit outward, forming the illumination effect of the front and back of the double-sided light-emitting mirror structure.

[0068] It should be noted that the light-emitting component 20 is structurally designed to match the shape and size of the first light-transmitting area 110 and the second light-transmitting area 120, and its light-emitting range completely covers the light-transmitting area of ​​the light-transmitting area to ensure that the light can be uniformly and efficiently transmitted through the mirror.

[0069] In some embodiments, two first light-transmitting areas 110 are provided on the first mirror 11, and two corresponding second light-transmitting areas 120 are provided on the second mirror. The two first light-transmitting areas 110 can be disposed on the left and right edge areas of the double-sided light-emitting mirror structure, distributed vertically in a strip shape along the height direction of the mirror surface. Similarly, the two second light-transmitting areas 120 are symmetrically disposed on the left and right sides of the second mirror 12, corresponding one-to-one with the positions of the first light-transmitting areas 110. Two light-emitting components 20 are correspondingly disposed within the first cavity 13 formed by the first frame 10. During installation, the two light-emitting components 20 are fixed inside the first cavity 13 of the mirror body, with their first light-emitting surface 33 and second light-emitting surface 34 facing the first light-transmitting area 110 and the second light-transmitting area 120 respectively, ensuring that light can directly pass through the light-transmitting areas and be emitted outwards. This double-sided layout avoids the facial shadow problem caused by single-sided lighting. Light is evenly emitted from both sides of the double-sided light-emitting mirror structure, forming a surround lighting effect, reducing facial shadows, and improving the uniformity of light and the quality of makeup lighting when looking in the mirror.

[0070] It should be noted that the light-transmitting areas (such as the first light-transmitting area 110 and the second light-transmitting area 120) on the first mirror 11 and the second mirror 12 can be set to one or more as needed. Each light-transmitting area is configured with one or shares one light-emitting component 20. When multiple light-emitting components 20 are set, each light-emitting component 20 is installed independently but functions collaboratively.

[0071] In some embodiments, to simplify wiring and improve safety and aesthetics, multiple light-emitting components 20 are connected in parallel. Specifically, the light sources 202 in each light-emitting component 20 are connected to the same power supply in parallel via wires. The parallel circuit ensures that all light-emitting components 20 operate at the same voltage, avoiding uneven voltage drop and brightness differences caused by series connection. All parallel lines are ultimately combined into a set of power leads, which are led out from the first frame 10 and connected to an external power supply. This design reduces the number of external power leads. Even if multiple light-emitting components 20 are integrated inside the double-sided light-emitting mirror structure, only one power line is needed, avoiding the safety hazards caused by multiple exposed wires.

[0072] Furthermore, in the double-sided light-emitting mirror structure, the light emitted by the light-emitting component 20 can be divided into primary illumination light and secondary illumination light according to the light output direction and functional positioning, respectively serving different usage states and user needs of the mirror door.

[0073] For example, when the double-sided light-emitting mirror structure serves as a mirror door, a portion of the light emitted from the light-emitting surface 30 is emitted outward through the first light-transmitting area 110. This direction corresponds to the outer mirror (i.e., the first mirror 11) when the mirror door is closed or in the external use state. This light serves as the primary illumination light, directly illuminating the front of the user's face, providing high-brightness, high-color-rendering frontal illumination. Another portion of the light emitted from the light-emitting surface 30 is emitted outward through the second light-transmitting area 120. This direction corresponds to the inner mirror (i.e., the second mirror 12) when the mirror door is open and in the internal use state. This light serves as the secondary illumination light, mainly used for auxiliary illumination of the user's face after the mirror door is opened.

[0074] In this embodiment, as Figure 3 As shown, part of the light beam emitted by the light source 202 is refracted by the incident light surface 31, and its light path is guided to the exit light surface 30. Among the light beams emitted through the exit light surface 30, the light beam emitted outward through the first light-transmitting area 110 forms the main front illumination light, and the light beam emitted outward through the second light-transmitting area 120 forms the auxiliary back illumination light.

[0075] Furthermore, in order to improve the uniformity of light output and avoid the phenomenon that the side closer to the light source 202 is too bright and the side farther away from the light source 202 is too dark, a large number of scattering particles 50 are dispersed inside the light guide plate 201. The scattering particles 50 are made of materials with different optical properties than the substrate material of the light guide plate 201, for example, their refractive index is different from that of the substrate material of the light guide plate 201.

[0076] When light enters the light guide plate 201 from the light source 202, it mainly propagates forward inside the light guide plate 201 by total internal reflection. When the light encounters scattering particles 50 in the propagation path, it will be reflected, breaking the condition of total internal reflection, thereby causing a part of the light to change direction and be emitted from the light emitting surface 30. The denser the scattering particles 50 are, the higher the probability that the light will be reflected and exited from the light guide plate 201.

[0077] like Figure 3 As shown, the area near the light source 202 is defined as the near-light source region, and the area far from the light source 202 is defined as the far-light source region. In the near-light source region, the light intensity emitted by the light source 202 is the strongest. If the density of scattering particles 50 in this region is too high, a large amount of light will be reflected too early and too quickly, causing the area near the light source 202 to be abnormally bright, forming bright spots. In the far-light source region, as the light propagates, its intensity will naturally attenuate due to distance and absorption.

[0078] In this embodiment, as Figure 3As shown, the distribution density of scattering particles 50 gradually increases from the near-light source area to the far-light source area. Thus, near the light-incident surface 31 of the light source 202, there is a lower density of scattering particles 50, with fewer scattering particles 50 per unit volume (sparse density), allowing most of the strong light to penetrate this area and continue propagating to the far-light source area, effectively preventing excessive light emission and brightness in the near-light source area. As the distance from the light source 202 increases, the density of scattering particles 50 gradually increases, with more scattering particles 50 per unit volume (dense density), causing more remaining light to be scattered and discharged here, thus compensating for the brightness attenuation caused by distance. Ultimately, this balances the luminous flux output of the entire light-emitting surface 30, resulting in highly uniform illumination across the entire light-emitting surface 30 with no significant differences in brightness, thus improving the lighting quality.

[0079] In the double-sided light-emitting mirror structure provided by this utility model, since the distribution of the scattering particles 50 inside the light guide plate 201 is controlled for the entire light guide plate 201, the above-mentioned brightness uniformity effect will act on the entire light-emitting surface 30, ensuring that whether it is used for the user's main lighting (such as light emitting from one side of the first light-transmitting area 110) or auxiliary lighting (such as light emitting from one side of the second light-transmitting area 120), it can provide uniform and soft light to meet the needs of high-quality makeup or lighting.

[0080] In some embodiments, the manufacturing process of the light guide plate 201 is typically injection molding or extrusion molding. Scattering particles 50 can be mixed into the liquid light guide plate material before it is solidified to achieve the structure of the light guide plate 201 provided in this embodiment.

[0081] In summary, the double-sided light-emitting mirror structure provided by this utility model embodiment achieves the effect of simultaneous light emission from both sides by setting a light-emitting component within the first cavity formed by the first mirror, the second mirror, and the first frame, and designing the light source and light guide plate structure of the light-emitting component. Furthermore, by gradually increasing the distribution density of scattering particles from the near-light source area to the far-light source area, highly uniform illumination is achieved. Specifically, when the double-sided light-emitting mirror structure is closed as a mirror door, light passes through the first light-transmitting area, providing the main illumination light for the outer mirror (i.e., the first mirror); when the double-sided light-emitting mirror structure is opened as a mirror door, light can also be emitted outward through the second light-transmitting area, providing continuous auxiliary illumination light for the inner mirror (i.e., the second mirror). Users can still obtain sufficient light in front of the inner mirror (i.e., the second mirror), avoiding the problem of lighting interruption caused by opening the door, improving the unpleasant user experience of frequently opening and closing the mirror door, and enhancing ease of use. At the same time, this double-sided light-emitting mirror structure is simple in design, low in cost, and can meet the requirements of industrial production.

[0082] Optional, such as Figure 3 As shown, the light-emitting surface 30 includes a first light-emitting surface 33 and a second light-emitting surface 34 that are disposed opposite to each other.

[0083] The light guide plate 201 also includes a reflective surface 32 opposite to the light incident surface 31.

[0084] The light-incident surface 31 is connected to one end of the first light-emitting surface 33 and the second light-emitting surface 34, and the reflective surface 32 is connected to the other end of the first light-emitting surface 33 and the second light-emitting surface 34.

[0085] The first light-emitting surface 33 is positioned opposite to the first light-transmitting area 110, and the second light-emitting surface 34 is positioned opposite to the second light-transmitting area 120.

[0086] Specifically, such as Figure 3 As shown, the light-incident surface 31 of the light guide plate 201 has a first light-emitting surface 33 and a second light-emitting surface 34 arranged opposite to each other. The light-emitting component 20 is precisely fixed during assembly so that the first light-emitting surface 33 of the light guide plate 201 faces the first light-transmitting area 110 on the first mirror 11, and the second light-emitting surface 34 faces the second light-transmitting area 120 on the second mirror 12. In this way, it is ensured that more light emitted from the first light-emitting surface 33 and the second light-emitting surface 34 can pass through the first light-transmitting area 110 on the first mirror 11, which is beneficial to improving the utilization efficiency of light and the uniformity of illumination.

[0087] The light guide plate 201 also has a reflective surface 32 disposed opposite to the light incident surface 31. The reflective surface 32 can be a vertical plane, an inclined plane, or a micro-arc surface structure. A high-reflectivity reflective film can be applied to the reflective surface 32 by pasting, spraying, or vacuum coating processes. The reflective film can be made of materials such as white polyethylene terephthalate (PET) reflective film, aluminum foil reflective sheet, or multilayer dielectric reflective coating, and its reflectivity is usually greater than 90%, preferably reaching more than 95%, in order to minimize light energy loss.

[0088] In this embodiment, the light beam emitted by the light source 202 is guided by the optical path inside the light guide plate 201 and then emitted from the first light-emitting surface 33 and the second light-emitting surface 34 respectively, and directly passes through the corresponding first light-transmitting area 110 or the second light-transmitting area 120 to emit outward, forming the illumination effect of the front and back of the double-sided light-emitting mirror structure.

[0089] Specifically, such as Figure 3 As shown, a portion of the light beam emitted by the light source 202 (e.g., the first light beam 41) is refracted by the light-incident surface 31, and its light path is directly guided to the first light-out surface 33. Finally, it is emitted outward through the first light-transmitting area 110 to form the main illumination light on the front.

[0090] Part of the light beam emitted by the light source 202 (e.g., the second light beam 42) is refracted by the incident light surface 31 and then directed to the reflecting surface 32. After being reflected by the reflecting surface 32, it is then transmitted to the first light-emitting surface 33 and emitted through the first light-transmitting area 110 as a supplement to the main illumination light. The recycling of this part of the light beam further enhances the brightness of the main illumination light.

[0091] Part of the light beam emitted by the light source 202 (e.g., the third light beam 43) is refracted by the light incident surface 31 and directly guided to the second light emitting surface 34, and emitted outward through the second light transmission area 120 to form the back auxiliary illumination light.

[0092] The reflective surface 32 reflects the light energy that might otherwise escape from the end of the light guide plate 201 back into the light guide plate 201 for secondary use, reducing the waste of light energy and improving the light efficiency of the entire double-sided light-emitting mirror structure.

[0093] Optionally, the light transmittance of the scattering particles 50 is lower than that of the light transmittance of the light guide plate 201 material.

[0094] In this method, by setting the transmittance of the scattering particles 50 to be lower than that of the light guide plate 201 material, light is more likely to be reflected rather than directly transmitted when it encounters the scattering particles 50, thereby improving the light output efficiency.

[0095] In some embodiments, the absolute value of the difference between the light transmittance of the scattering particles 50 and the light transmittance of the light guide plate 201 material is not less than 60%; or, the light transmittance of the scattering particles 50 is more than 3 times the light transmittance of the light guide plate 201 material. In this way, when light propagates to the surface of the scattering particles 50, it cannot penetrate and can only be reflected or diffusely scattered, thereby effectively breaking the total internal reflection condition and causing the light to be emitted from the light-emitting surface.

[0096] For example, the light guide plate 201 material has a light transmittance of 92%, and the light transmittance of the scattering particles 50 is controlled between 20% and 30% to improve the light output efficiency, but is not limited to this.

[0097] Optionally, the particle size of the scattering particles 50 is greater than or equal to 10 μm and less than or equal to 100 μm.

[0098] When the size of the scattering particles 50 is much smaller than the wavelength of light (visible light wavelength is about 0.38μm~0.78μm), Rayleigh scattering will occur. The intensity of Rayleigh scattering is inversely proportional to the fourth power of the wavelength, which will cause short-wavelength blue light to be strongly scattered, while long-wavelength red light will be scattered weakly. This will cause light dispersion, resulting in uneven light color (for example, blue when viewed from the side, and yellow when viewed from the front).

[0099] In this embodiment, the lower limit of the particle size of the scattering particles 50 is set at 10 μm, which is much larger than the wavelength of light. This ensures that the scattering mechanism is mainly geometric optical scattering, and the scattering effect on all visible light wavelengths is basically the same, thereby ensuring the uniformity and consistency of the emitted light color and preventing color separation.

[0100] Furthermore, if the scattering particles 50 have an excessively large particle size (e.g., exceeding 100 μm), they will first be difficult to disperse uniformly during manufacturing and material mixing, easily causing local aggregation and forming visible defects or bright / dark spots. Secondly, excessively large scattering particles 50 may become macroscopic defects, potentially forming visible bright spots or shadows on the light-emitting surface when directly illuminated, affecting the uniformity and aesthetics of the emitted light.

[0101] In this embodiment, the upper limit of the particle size of the scattering particles 50 is set to 100μm to ensure that the scattering particles 50 are microscopic and dense throughout the entire light guide plate 201, and will not form visible bright or dark spots or defects, thereby achieving a uniform surface light effect.

[0102] In some embodiments, the scattering particles 50 are micron-sized opaque or semi-transparent particles, preferably white plastic microspheres, silicon dioxide (SiO2) microparticles or titanium dioxide (TiO2) particles. The above materials have high refractive index, stable chemical properties, and good compatibility with the light guide plate 201 substrate. They can produce extremely strong reflection and scattering of visible light, rather than absorption or transmission, which is beneficial to improving light extraction efficiency.

[0103] In some embodiments, the surface of the scattering particles 50 is treated to enhance adhesion to the substrate of the light guide plate 201 and prevent delamination or agglomeration.

[0104] Optionally, along the extending direction of the optical axis 2020 of the light source 202, the width of the first light-emitting surface 33 is equal to the width of the second light-emitting surface 34.

[0105] Among them, such as Figure 1 As shown, the width of the first light-emitting surface 33 is W1, and the width of the second light-emitting surface 34 is W2, where W1 = W2. With this configuration, provided that the dimensions in the height direction are the same, the light-emitting area of ​​the first light-emitting surface 33 is equal to the light-emitting area of ​​the second light-emitting surface 34, ensuring that the first light-emitting surface 33 and the second light-emitting surface 34 can output light of the same brightness.

[0106] In this way, the user perceives a consistent level of lighting brightness when using the external mirror (when the mirror door is closed) or the internal mirror (when the mirror door is open), eliminating sudden changes in light caused by structural position changes and providing a consistent and comfortable user experience.

[0107] In some embodiments, the reflective surface 32 is perpendicular to the optical axis 2020, that is, the reflective surface 32 is a plane at a 90-degree angle to the main direction of light propagation (i.e., the optical axis 2020), which can provide consistent reflection conditions for light arriving from different positions, and the light emission efficiency of the first light-emitting surface 33 and the second light-emitting surface 34 will not be different due to the change of the angle of the reflective surface 32 itself.

[0108] Furthermore, the reflective surface 32 maintains a stable light recovery and redistribution mechanism, working in conjunction with the internal scattering particles 50, which is beneficial for achieving a uniform brightness distribution on the first light-emitting surface 33 and the second light-emitting surface 34.

[0109] Optionally, along the extending direction of the optical axis 2020 of the light source 202, the width of the first light-transmitting area 110 is greater than or equal to the width of the second light-transmitting area 120.

[0110] Specifically, in some embodiments, such as Figure 1 As shown, the width of the first light-transmitting area 110 is W3, and the width of the second light-transmitting area 120 is W4, where W3 > W4. The wider first light-transmitting area W3 allows more light beams to exit from the first light-emitting surface 33, while the narrower second light-transmitting area W4 limits the light flux exiting from the second light-emitting surface 34. With this configuration, users can obtain high-brightness, wide-range illumination when using the external mirror (with the mirror door closed) to complete fine operations such as makeup and shaving; while when using the internal mirror (with the mirror door open), it can meet the needs of operations with lower lighting requirements, such as retrieving items or quick grooming.

[0111] In this embodiment, the width difference between the first light-transmitting area 110 and the second light-transmitting area 120 is used to achieve the proportional distribution of the main front lighting light and the auxiliary back lighting light, guiding the light beam to be output to the main lighting side first, which conforms to the user's usage logic, realizes on-demand lighting and reasonable allocation of light sources, and is conducive to improving overall energy efficiency.

[0112] It is understood that by adjusting the width of the first light-transmitting area 110 and the second light-transmitting area 120, the light intensity on both sides of the double-sided light-emitting mirror structure can be flexibly controlled. The wider the light-transmitting area, the more light flux is allowed to escape from the light-emitting surface. The specific widths of the first light-transmitting area 110 and the second light-transmitting area 120 can be set according to actual needs, and this embodiment of the invention does not impose specific limitations on this.

[0113] In some embodiments, the width W3 of the first light-transmitting area 110 is equal to the width W4 of the second light-transmitting area 120, i.e., W3 = W4. This configuration allows the first light-transmitting area 110 and the second light-transmitting area 120 to output light of the same brightness. When the user uses the outer mirror (when the mirror door is closed) or the inner mirror (when the mirror door is open), the perceived lighting brightness is consistent, eliminating abrupt changes in light caused by structural position variations and providing a consistent and comfortable user experience.

[0114] Optionally, along the extending direction of the optical axis 2020 of the light source 202, the width of the first light-transmitting area 110 is smaller than the width of the first light-emitting surface 33. Along the extending direction of the optical axis 2020 of the light source 202, the width of the second light-transmitting area 120 is smaller than the width of the second light-emitting surface 34.

[0115] By setting the width of the first light-transmitting area 110 to be smaller than the width of the first light-emitting surface 33, and the width of the first light-transmitting area 110 to be smaller than the width of the first light-emitting surface 33, even if the light-emitting component 20 has a slight offset during the assembly process, its first light-emitting surface 33 can still cover the first light-transmitting area 110, and its second light-emitting surface 34 can still cover the second light-transmitting area 120, thereby ensuring normal light emission and improving the fault tolerance rate and yield rate of production assembly.

[0116] Optional, such as Figure 3 As shown, the light-emitting component 20 also includes a packaging material 203 covering the outside of the light guide plate 201 and the light source 202, and the material of the packaging material 203 is a light-transmitting material.

[0117] Specifically, such as Figure 3 As shown, the packaging material 203 serves as an encapsulation component, enclosing the assembled light guide plate 201 and light source 202 within it. The packaging material 203 tightly secures the light guide plate 201, light source 202, and other possible optical films (such as reflective films) together, forming a stable and integrated light-emitting module. This prevents internal components from loosening or shifting due to vibration or handling, improving structural reliability and durability. Simultaneously, it effectively blocks the intrusion of dust and moisture, making it particularly suitable for humid environments such as bathrooms, and helping to extend the lifespan of the light-emitting component 20.

[0118] In some embodiments, the packaging material 203 is made of a light-transmitting and diffusing material, such as a diffusing light-transmitting plastic film. When the light beam is emitted from the first light-emitting surface 33 and the second light-emitting surface 34 of the light guide plate 201, it will pass through the packaging material 203. The packaging material 203 can perform secondary diffusion and homogenization on the transmitted light beam, further softening the light and eliminating possible tiny bright spots or the imaging of dots on the light guide plate 201, making the light emission effect more uniform.

[0119] Based on the same inventive concept, this utility model also provides a folding mirror. Figure 4 and Figure 5 This is a schematic diagram of the structure of a folding mirror provided in an embodiment of the present invention, as shown below. Figure 4 and Figure 5 As shown, the folding mirror includes:

[0120] The second border is 60.

[0121] The third mirror 61 and the fourth mirror 62 are respectively located on two opposite sides of the second frame 60 and are both connected to the second frame 60.

[0122] The folding mirror also includes the double-sided light-emitting mirror structure 70 provided in any of the above embodiments, wherein the first frame 10 and the second frame 60 of the double-sided light-emitting mirror structure 70 are hinged together. Therefore, the folding mirror provided in this embodiment of the present invention has the technical effects of the technical solutions in any of the above embodiments, and the explanations of the same or corresponding structures and terms as in the above embodiments will not be repeated here.

[0123] Specifically, such as Figure 4 and Figure 5 As shown, the second frame 60 serves as the supporting frame for the entire mirror body. It can be assembled from multiple metal profiles (for example, four metal strips connected end to end in sequence) by screws to form a rectangular frame, which has good structural stability and corrosion resistance.

[0124] Furthermore, the third mirror 61 is connected to one end of the inner wall of the second frame 60, and the fourth mirror 62 is connected to the other end of the inner wall of the second frame 60. The third mirror 61 and the fourth mirror 62 are arranged opposite to each other. That is, the third mirror 61 and the fourth mirror 62 are pasted on the front and back of the second frame 60 respectively. The third mirror 61 and the fourth mirror 62 are parallel to each other and are firmly connected to the second frame 60. The above structure makes the folding door form a double-sided mirror structure.

[0125] The specific construction of the double-sided light-emitting mirror structure 70 can be referred to the above embodiment, and will not be repeated here.

[0126] In this embodiment, the first frame 10 and the second frame 60 of the double-sided light-emitting mirror structure 70 are hinged together, which can realize a folding and opening design. This not only saves space, but also allows the folding mirror to be flipped according to the user's needs, so that the double-sided light-emitting mirror structure 70 is closer to the user. The light on the double-sided light-emitting mirror structure 70 also gets closer to the user as the folding mirror is flipped, thereby providing the user with sufficient lighting and expanding the spatial flexibility of looking in the mirror and applying makeup.

[0127] Optional, such as Figure 4 and Figure 5 As shown, the third mirror 61, the fourth mirror 62, and the second frame 60 form a second cavity (not shown in the figure).

[0128] A hinge 80 is provided between the first frame 10 and the second frame 60.

[0129] The light source is connected to a power cord, which passes through the first frame 10, the hinge 80 and the second frame 60 in sequence, extends into the second cavity, and extends out from the side of the second frame 60 away from the first frame 10 to connect to the power source.

[0130] Specifically, such as Figure 4 and Figure 5 As shown, the first frame 10 and the second frame 60 are hinged together by the hinge 80.

[0131] In some embodiments, the hinge 80 may be a pin (or pivot, axle bolt) to achieve stable and smooth relative rotation between the first frame 10 and the second frame 60.

[0132] It should be noted that the type of hinge 80 is not limited to a pin; it can be any connecting component commonly found in the art that can achieve a hinge function. For example, hinge 80 can also be a hinge, a chain, or other functionally equivalent rotating connection structure, and those skilled in the art can flexibly choose according to actual needs.

[0133] Furthermore, in the double-sided light-emitting mirror structure, the power line is led out from the light source of the light-emitting component. The power line first passes through the first frame 10, then through the internal channel of the hinge 80 (e.g., a hollow pivot), then enters and passes through the second frame 60, and finally extends into the second cavity formed by the third mirror 61, the fourth mirror 62, and the second frame 60. The power line 90 extends within the second cavity and finally exits from the side of the second frame 60 away from the hinge side (i.e., away from the first frame 10) to connect to an external power source fixed to a wall or cabinet.

[0134] It should be noted that when the double-sided light-emitting mirror structure is provided with multiple light-emitting components, the multiple light-emitting components are connected in parallel through power lines in the first cavity. Then, the bus connecting the multiple power lines passes through the first frame 10, the hinge 80 and the second frame 60 in sequence and extends into the second cavity, and extends out from the side of the second frame 60 away from the first frame 10 to connect with the power supply.

[0135] In this embodiment, the power cord is completely hidden inside the frame and hinge, avoiding tangling and improving aesthetics.

[0136] Meanwhile, the power cord is properly stored and secured inside the hinge 80, which can prevent it from being squeezed, worn or pulled during repeated opening and closing, reducing the risk of short circuits and open circuits, and improving the safety and service life of the product.

[0137] Based on the same inventive concept, this utility model also provides a bathroom cabinet. Figure 6 and Figure 7 A schematic diagram of the structure of a bathroom cabinet provided for an embodiment of this utility model is shown below. Figure 6 and Figure 7 As shown, the bathroom vanity includes:

[0138] The cabinet is 90mm wide and has a mounting surface.

[0139] The mirror door 91 is hinged to one edge of the mounting surface.

[0140] In any of the above embodiments, the second frame 60 of the folding mirror 100 is hinged to the opposite edge of the mounting surface on the side away from the first frame 10.

[0141] Specifically, such as Figure 6 and Figure 7 As shown, cabinet 90 contains storage space. As the main storage structure, its front has a mounting surface for installing mirror door 91 and folding mirror 100.

[0142] The mirror door 91 is a single-sided door that can be opened and closed, and its front is usually also a mirror. One edge of the mirror door 91 is hinged to one edge of the mounting surface (for example, the left or right side) by a hinge, and it can be opened and closed like a regular cabinet door. When the mirror door 91 is closed, it covers the internal storage space of the cabinet 90, and serves to prevent dust and water. When the mirror door 91 is open, the user can take out and put in toiletries, cosmetics and other items.

[0143] The specific structure of the folding mirror 100 can be referred to any of the above embodiments. The bathroom cabinet provided by this utility model embodiment has the technical effects of the technical solution in any of the above embodiments. The explanations of the same or corresponding structures and terms as those in the above embodiments will not be repeated here.

[0144] Furthermore, the folding mirror 100 is hinged to the opposite edge of the mounting surface, opposite the hinge position of the mirror door 91, on the side of its second frame 60 away from the first frame 10 (i.e., the side not connected to the double-sided light-emitting mirror structure 70). The folding mirror 100 can be connected to the mounting surface in an "outward folding" or "inward folding" manner, forming an unfoldable mirror assembly structure independent of the mirror door 91.

[0145] The folding mirror 100 and mirror door 91 are hinged to both sides of the cabinet body 90, forming a symmetrical opening and closing structure and improving spatial harmony. Users can use the double-sided luminous mirror structure 70 and mirror door 91 simultaneously, or fold them up for storage to save space.

[0146] In some embodiments, such as Figures 4-7 As shown, the folding mirror 100 is hinged to the mounting surface of the cabinet 90 through one or more hinges 81, so that the folding mirror 100 can be opened, closed and rotated relative to the cabinet 90.

[0147] It should be noted that the hinge 81 mentioned above is a general component used to connect the cabinet 90 and the folding mirror 100. Its specific type can be a hinge, a damping hinge or any other rotating connection mechanism with equivalent function. This utility model does not limit this.

[0148] In some embodiments, the width of the mirror door 91 is greater than the width of the folding mirror 100, but it is not limited to this. The mirror door 91, as the main mirror surface of the bathroom cabinet and a door that is opened frequently, has a larger width that conforms to user habits and visual expectations, making it the visual focus of the space while maintaining a simple and elegant appearance, suitable for users to observe their overall attire and appearance. The folding mirror 100, as an auxiliary mirror structure, is installed on one side of the mirror door 91, allowing users to unfold or fold it as needed. The folding mirror 100 is narrower, providing more mirror angles within a limited space.

[0149] In some embodiments, such as Figure 6 and Figure 7 As shown, the front of the mirror door 91 is a mirror, and a back mirror 901 is also fixed (e.g., pasted) on the side of the cabinet 90 facing away from the wall. With this arrangement, the mirror on the front of the mirror door 91, the back mirror 901 of the cabinet 90, and the multiple mirrors on the folding mirror 100 can provide users with multiple directions of reflection. By tilting the folding mirror 100, users can create various combinations and reflection angles with the mirror on the front of the mirror door 91 and the back mirror 901, thus easily observing the sides and back of the head, which are difficult to achieve with traditional fixed mirrors, and realizing a more flexible multi-angle reflection method.

[0150] In some embodiments, when both the folding mirror 100 and the mirror door 91 are closed, the mirror surface of the third mirror 61 of the folding mirror is flush with the mirror surface of the mirror door 91. When the two mirror surfaces are flush in the closed state, misalignment gaps are eliminated, resulting in a seamless overall mirror effect, which improves aesthetics.

[0151] It should be noted that the integrated light-emitting component on the folding mirror 100 makes the lighting independent of the opening and closing state of the mirror door 91. Specifically, when the mirror door 91 is closed, the light on the folding mirror 100 can provide illumination. When the mirror door 91 is open, the light on the folding mirror 100 remains effective and can work in conjunction with the back mirror 901 of the cabinet 90 exposed after the mirror door 91 is opened, providing sufficient lighting for the user while retrieving or placing items.

[0152] The specific embodiments described above do not constitute a limitation on the scope of protection of this utility model. Those skilled in the art should understand that various modifications, combinations, sub-combinations, and substitutions can be made according to design requirements and other factors. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
