Description

A tungsten filament or carbon filament light source skin beauty mirror Technical Field

[0001] The present application relates to the technical field of beauty and skin care equipment, and in particular to a skin care mirror with a tungsten filament or carbon filament light source. Background Art

[0002] Most current beauty devices on the market use a single IPL light source for hair removal, whitening, and skin rejuvenation. While higher IPL energy levels lead to more pronounced treatment effects, they can also cause varying degrees of burning and pain. Furthermore, higher energy levels result in slower flash rates and shorter lamp lifespans. Furthermore, because IPL uses intense pulsed light with short durations and high peak energy, its spectrum is less continuous. This significantly reduces lamp efficiency when targeted wavelengths are needed for specific skin tones and treatment needs (e.g., DPL), such as for freckle removal, whitening, skin rejuvenation, and wrinkle reduction. Furthermore, the near-infrared spectrum above 1200nm is limited in IPL light sources, making them inappropriate for beauty treatments. The limited wavelength range and low optical power of IPL light sources make them ineffective in addressing various skin concerns. Existing beauty devices also use a single LED light source for skin care. However, LEDs have low optical power and are therefore ineffective in addressing various skin concerns. Technical issues

[0045] The present application relates to a photon skin-beautifying mirror, the light source of which is a tungsten filament or carbon filament light source. The tungsten filament light source or carbon fiber light source uses tungsten filament or carbon fiber as the filament, i.e., the luminescent material. The filament is installed in a transparent lampshade and emits light when energized. The lampshade is kept in a vacuum or filled with a low-pressure inert gas or halogen gas to prevent the filament from oxidizing at high temperatures. When the transparent lampshade of the tungsten filament light source or carbon fiber light source is filled with a halogen gas such as iodine or bromine, a halogen lamp (also known as a tungsten halogen lamp) is obtained. The tungsten filament light source or carbon fiber light source is an incandescent light source and is implemented using the structure of an incandescent lamp.

[0046] Tungsten filament and / or carbon fiber is used as the light-emitting material, i.e., filament. A certain proportion of inert gas or halogen gas can be filled in the transparent lampshade to increase the life of the light source. The spectral distribution of the tungsten filament and / or carbon fiber light source can be changed by adjusting the gas pressure and gas ratio in the lamp, adjusting the current pulse or supply voltage, etc.

[0047] Tungsten filament or carbon fiber light sources offer full-spectrum and constant-on characteristics. They generate a full spectrum of light, including both visible and invisible light. After filtering through filters, light in predetermined wavelengths is obtained for skin beautification or treatment. For example, visible light in the 500-600nm band can reduce epidermal melanin, while near-infrared light in the 900-2500nm band can directly reach the dermis and basal layer, stimulating collagen regeneration and repairing the basal layer.

[0048] Please refer to Figures 1-3. The tungsten filament or carbon filament light source beauty mirror 1000 of the first embodiment of the present application includes a shell 100 and a transparent substrate 10, a filter 11, a tungsten filament or carbon filament light source 20, a reflector 21, a reflector heat sink 22, a temperature sensor assembly 30, a heat shield 40, a main control board 50 and a battery 60 installed in the shell 100.

[0049] The overall shape of the tungsten filament or carbon filament light source beauty mirror 1000 can be spherical, hemispherical, square or other shapes, and a large window is provided at its front end. The shell 100 includes a front shell 110 and a rear shell 120. The shell 100 as a whole is spherical, hemispherical (including quasi-hemispherical or partially spherical), square or other shapes. The front shell 110 is buckled on the front end of the rear shell 120, so that the above components are assembled between the front shell 110 and the rear shell 120 or in the internal cavity of the shell. For example, the front shell 110 is annular, and the rear shell 120 is a hemispherical or quasi-hemispherical shell. The front end of the rear shell is open, and the annular front shell 110 is connected to the edge of the front opening of the rear shell 120 to form the large window. The transparent substrate 10 covers the large window at the front end of the beauty mirror to form a large light-emitting surface as a mirror surface.

[0050] The transparent substrate 10 and the filter 11 are fixedly mounted on the front housing 110 and have matching shapes. The transparent substrate 10 can be made of sapphire, quartz, K9, glass, transparent plastic or other light-transmitting materials. Preferably, the transparent substrate 10 is made of transparent crystal.

[0051] In this embodiment, the transparent substrate 10 is a solid transparent crystal. The temperature of the transparent substrate (transparent crystal) 10 is controlled by a temperature sensor assembly 30. The solid transparent crystal covers the large window at the front of the skin-beautifying mirror, forming a large light-emitting surface that also serves as a mirror. This light-emitting surface is approximately the same size as the entire front surface of the skin-beautifying mirror, enabling large-area full-body skin beautification, making it quicker and more efficient to use.

[0052] The filter 11 is attached to one side of the transparent substrate (transparent crystal). For example, the shape of the filter 11 is adapted to the shape of the entire transparent crystal, for example, both are circular. The filter 11 is attached to the entire surface of the transparent crystal, for example, attached to the inner side of the transparent crystal, and covers the light outlet of the reflector 21, and the tungsten filament or carbon filament light source 20 is sealed in the reflector 21.

[0053] The optical filter 11 of this embodiment is independently provided and can be a single-piece single-band, a single-piece multi-band, a single-piece zoned coating, a multi-piece, etc. The optical filter can be manufactured using existing technology, for example, by optical coating technology or the following filter film.

[0054] In some embodiments, the optical filter 11 is fabricated by forming a coating layer on the surface of a transparent substrate using a coating process. Examples of coating processes include evaporative deposition, ion beam sputtering (IBS), plasma sputtering, and atomic layer deposition (ALD). In evaporative deposition, a source material in a vacuum chamber is heated or bombarded with an electron beam, causing it to evaporate. The vapor condenses onto the surface of the transparent substrate, forming a uniform coating layer. In the ion beam sputtering (IBS) process, a high-energy electric field accelerates an ion beam. This acceleration imparts significant kinetic energy to the ions. Upon impact with the source material, the ion beam "sputters" atoms from the target material. These sputtered target ions (atoms transformed into ions by the ionization zone) also possess kinetic energy and form a dense film upon contact with the transparent substrate surface. Plasma sputtering is a general term for a range of technologies, such as plasma sputtering and magnetron sputtering. Ions in a plasma are accelerated into the source material, colliding with loose energy source ions, which are then sputtered onto the transparent substrate, forming a uniform coating layer. In the atomic layer deposition (ALD) process, the source material used for atomic layer deposition (ALD) exists directly in gaseous form. In a high-temperature vacuum chamber, the vapor precursor is delivered via non-overlapping pulses and deposited on the surface of a transparent substrate, forming a coating layer. The transparent substrate of the filter 11 serves as a support and light-transmitting element. The coating layer forms a filter film, integrally (inseparably) attached to the transparent substrate. Multilayer coatings can be used, employing multiple materials and processes to achieve filtering performance that passes a predetermined wavelength band.

[0055] In some embodiments, a coating layer is formed on a transparent substrate according to the above-mentioned coating process; wherein, a single-interval band filter that passes a single interval band is obtained by single-interval band coating, for example, a single-interval band filter that passes the 500-1800nm, 900-1800nm, and 500-600nm bands; or, a multi-band filter that passes multiple bands simultaneously is obtained by multi-interval band coating, for example, a dual-band filter that passes the 500-600nm + 900-1800nm ​​bands obtained by dual-interval band coating; or, a multi-zone filter that passes multiple zones with different bands is obtained by zone coating on a transparent substrate, for example, the filter obtained by zone coating has zone A: light in the 500-600nm band passes; zone B: light in the 900-1800nm ​​band passes.

[0056] The optical filter 11 can be a conventional optical filter. Different wavelength band treatments for different skin problems can be achieved by switching different optical filters 11.

[0057] In some embodiments, an optical coating process can also be used to obtain a one-way perspective filter or filter film. For example, one side (e.g., the side facing the light source) transmits near-infrared light and filters visible light, while the other side (e.g., the side facing the user) reflects light. When the skin beauty mirror of the present application is used as a makeup mirror, the filter 11 provided therein or the filter film coated on the transparent substrate has one-way perspective, that is, the filter or filter film reflects light on one side, while the other side can filter out unwanted wavelengths and transmit a predetermined wavelength. For example, visible light is not transparent, but the near-infrared line of non-visible light is transparent. When the filter (film) is transparent to near-infrared light, visible light cannot pass through the filter (film), preferably, light with a wavelength of 760nm or above is transparent.

[0058] The skin-beautifying mirror 1000 can be configured with a photon skin-beautifying mode and a makeup mode. When the photon skin-beautifying mode is disabled, it can be used as a makeup mirror. When used as a makeup mirror, the mirror offers higher clarity and a more realistic display of skin. In photon skin-beautifying mode, the mirror utilizes a tungsten filament or carbon fiber light source to generate a full spectrum of light, including visible and invisible light. After filtering through the filter 11, light in a predetermined wavelength band is obtained for skin beautification or treatment.

[0059] The optical filter or filter film obtained by optical coating has a delicate molecular structure of its reflective layer at the microscopic level. The film is thinner, more uniform, and has a higher reflectivity, making it clearer when used as a beauty mirror.

[0060] In this embodiment, a tungsten or carbon filament light source 20 is installed within a reflector 21 to form a light source assembly, reflecting light and projecting it toward a transparent substrate (transparent crystal) 10. The reflector 21 is made of a thermally conductive material, with its edges aligning with the front edges of the front shell 110 and the rear shell 120, securing it between the front and rear shells. For example, the reflector is a (partial) spherical surface, with its edges secured by the front shell 110. The tungsten or carbon filament light source 20 is installed at the center of the inner top. A housing is formed at the top center of the reflector 21, with a through-hole extending from the interior of the reflector toward the rear. The tungsten or carbon filament light source 20 is inserted into the housing, and its electrodes extend rearward from the housing to connect with the main control board 50.

[0061] A heat sink 22 is provided on the back of the reflector. Its shape matches that of the reflector plate 21, as well as the shapes of the front and rear housings 110 and 120. It is fitted snugly to the back of the reflector 21 for rapid heat transfer. Alternatively, the heat sink 22 and reflector 21 may be integrally formed. The edges of the heat sink 22 are clamped to the front housing 110. The inner surface of the heat sink 22 matches the shape of the reflector's back, and in the examples shown, it is spherical, designed to maximize contact area and fit snugly. A through-hole is provided in the center of the heat sink 22. A seat provided at the top center of the reflector 21 passes through the through-hole to support the heat sink 22. The heat sink 22 is a heat transfer structure and can be made of a single thermally conductive material such as aluminum, copper, or graphene. Alternatively, it can be a heat pipe, vapor chamber (VC), super heat pipe, or super heat plate, such as ALVC (aluminum superconducting tube or plate), that utilizes phase change (evaporation and condensation).

[0062] The heat shield 40 is mounted on the outside of the rear side of the reflector 21 and the heat sink 22. For example, a through hole is provided in the center of the heat shield 40. The seat cover provided at the top center of the reflector 21 passes through the through hole in the center of the heat sink 22 and the through hole in the center of the heat shield 40 and then abuts against the main control board. After the tungsten filament or carbon filament light source 20 is mounted on the seat cover, its electrodes pass through the through hole in the heat shield and are electrically connected to the main control board 50. The shape of the heat shield 40 is adapted to the shape of the inner wall of the rear shell 120 and is tightly fitted to the inner wall of the rear shell. It can be made of an insulating material and separates the cavity in the rear shell from the front to the back, thereby isolating the light source assembly from the main control board 50 and protecting the main control board 50. For example, the heat shield 40 is disc-shaped.

[0063] The main control board 50 is installed within the cavity enclosed by the heat shield 40 and the rear housing 120. It is electrically connected to the switch assembly, the tungsten or carbon filament light source 20, the temperature sensor assembly 30, the battery 60, and the power supply interface 130. The main control board 50 is equipped with corresponding circuits and functional modules based on functional requirements. These circuits and functional modules can be configured using existing technologies or purchased from commercially available electronic components. For example, the main control board 50 is equipped with a power module, a control unit, a radio frequency module, a temperature control module, and the like.

[0064] Battery 60 can be a rechargeable battery, charged via power port 130. It can also be a disposable, replaceable battery. Alternatively, battery 60 can be omitted and the device can be powered directly by connecting directly to an external power source via power port 130. Battery 60 is also installed in the cavity enclosed by heat shield 40 and rear housing 120.

[0065] The power interface 130 is electrically connected to the main control board and passes through a through hole on the housing 100 for connecting to an external power source.

[0066] The housing 100 is provided with a switch assembly, and a power button, a light source control key, a mode setting key, a radio frequency switch, etc. are provided as needed.

[0067] In this embodiment, the temperature sensor assembly 30 is a temperature sensor PCBA, which can be a flexible PCBA, but is not limited thereto. It can also be other temperature sensors in the prior art. The front end of the temperature sensor assembly 30 contacts the transparent substrate to detect the temperature of the transparent substrate; the rear end is electrically connected to the main control board 50 to transmit the temperature information to the control unit on the main control board. When the light generated by the tungsten filament or carbon filament light source 20 is filtered by the filter 11 and passes through the transparent substrate 10 to irradiate the skin, the temperature of the transparent substrate is detected by the temperature sensor assembly 30, and the power and switching of the tungsten filament or carbon filament light source 20 are controlled by the main control board 50 to control the temperature range, thereby avoiding burns to the skin due to long-term use.

[0068] In the skin-beautifying mirror 1000 of this embodiment, light generated by a tungsten or carbon filament light source passes through a filter 11, then is irradiated onto the skin at a constant temperature through a transparent substrate 10. Light waves within a predetermined wavelength range are captured by the filter 11, allowing them to act on the skin in a targeted manner, achieving the purpose of beautifying and rejuvenating the skin. For example, light generated by the light source passes through a filter 11 with a wavelength range of 500-600nm, then acts on the epidermis of the human body from the light-emitting surface. Light generated by the light source passes through a filter 11 with a wavelength range of 900-1800nm, then acts on the basal layer and melanocytes of the human body from the light-emitting surface.

[0069] The skin beauty mirror of this embodiment can achieve multiple uses in one device. It has a photon skin beauty mode and a makeup mode, realizing a makeup mirror and a large-window beauty instrument, which greatly reduces the consumer's usage cost, usage time and maintenance cost. In the makeup mode, since the filter 11 adopts an optical coating method, compared with the conventional mirror using a spraying process, the skin beauty mirror of this embodiment is more delicate when used in the makeup mode. Since the molecular structure of the optical coating process is finer than that of the spraying process, the mirror clarity is higher. The tungsten filament or carbon filament light source is turned off in the makeup mode. In the skin beauty mode, the skin beauty mode can be selected through the function selection button or the tungsten filament or carbon filament light source 20 can be turned on through the light source switch: the light generated by the tungsten filament or carbon filament light source passes through the filter 11 to obtain light of a predetermined wavelength band, which is adhered to the skin through the transparent substrate 10. The size of the light emitting surface is approximately the size of the entire front end surface of the skin beauty mirror, which can achieve large-area whole-body skin beauty, and is faster and more efficient to use.

[0070] Referring to Figures 4-5 , the second embodiment of the present application's skin-beautifying mirror 1000 differs from the first embodiment in that the filter 11 (including a transparent substrate and a coating layer thereon) in the second embodiment is replaced by a transparent substrate (transparent crystal) 10. Specifically, an integral (inseparable) coating layer is formed on the surface of the transparent substrate (transparent crystal) 10 through an optical coating process, resulting in a transparent substrate 10 with a built-in filtering function. Light generated by a tungsten or carbon filament light source 20 passes through the transparent substrate 10 with a built-in filtering function (with a built-in filter film) to obtain light waves of a predetermined wavelength band that act on the skin. The transparent substrate 10 with a built-in filtering function (with a built-in filter film) can be obtained by applying a single-band, multi-band, or zoned coating to the surface of the transparent substrate 10, using the aforementioned optical coating method. Preferably, the filter film integrally formed with the transparent substrate 10 transmits wavelengths above 760 nm. After the light generated by the light source passes through the transparent substrate 10 with its inherent filtering function (filter film), light in the wavelength range above 760 nm is captured and applied to the skin surface. Similar to the first embodiment, the skin-beautifying mirror 1000 of the second embodiment has a makeup mode (serving as a makeup mirror) and a photonic skin-beautifying mode. The same structures and configurations as those of the first embodiment are directly referenced from the description of the first embodiment and are not further elaborated here.

[0071] Referring to Figures 6-9, the third embodiment of the present application shows a skin-beautifying mirror with a makeup mode and a photonic skin-beautifying mode. This embodiment differs from the first embodiment in that the transparent substrate 10 is replaced by a transparent semiconductor cooler 10'. A semiconductor cooler, also known as a thermoelectric cooler (TEC), heat pump, or Peltier cooler, comprises a central semiconductor particle layer 12, a hot surface 13, and a cold surface 15 at either end. It also includes a pair of positive and negative electrodes that electrically connect the semiconductor cooler's circuit to a control unit located on a main control board 50 or a separate control board, which is electrically connected to the main control board 50. The hot surface 13 and / or the cold surface 15 are configured as transparent substrates (e.g., transparent crystal). For example, the cold surface 15 is a transparent substrate that covers the window on the front of the skin-beautifying mirror, forming a large mirror surface, preferably a fully transparent crystal surface, that can contact the skin. The hot surface 13 and semiconductor particle layer 12 of the semiconductor cooler 10' are arranged in a ring shape. A hot-end circuit (e.g., a conductor) is provided on the annular edge of the transparent substrate cold surface 15 and is welded and electrically connected to the cold end of the semiconductor particle layer. A hot-end circuit (e.g., a conductor) is also provided on the hot surface 13 and is welded and electrically connected to the hot end of the semiconductor particle layer, thereby connecting the internal circuit of the semiconductor cooler. The positive and negative electrodes are electrically connected to the control unit via the positive and negative electrodes. The cold surface of the transparent substrate, corresponding to the middle region of the annular hot surface and the semiconductor particle layer, forms a light-emitting surface, which can be configured as a large light-emitting surface that approximates the entire front end of the skin-beautifying mirror. The hot surface of the semiconductor cooler is connected to a heat sink 16, which dissipates heat from the hot surface of the semiconductor cooler. Heat sink 16 is a heat transfer structure and can be made of a single thermally conductive material such as aluminum, copper, or graphene, or it can be a component that utilizes phase change (evaporation and condensation), such as a heat pipe, a heat spreader (VC), a superheat pipe, or a superheat plate such as an ALVC (aluminum superconducting tube or plate). In this embodiment, the heat sink 16 is annular, with its annular end surface rapidly transferring heat to the annular hot surface 13 of the semiconductor cooling element, and they can be positioned in close contact with each other. The annular heat sink 16 can be tightly fitted onto the front outer wall of the reflector, allowing for mutual contact and heat conduction. The shape of the filter 11 is adapted to the shape of the semiconductor cooling element and the light outlet of the reflector. In this embodiment, the filter 11 is independently provided, adapted to the shape of the semiconductor cooling element, for example, both are circular. The filter 11 seals the light outlet of the reflector 21, enclosing the tungsten or carbon filament light source 20 within the reflector 21. The filter 11 is positioned close to the inner surface of the cold surface 15 of the transparent substrate. The filter 11 can be obtained by optical coating on a transparent substrate. It can be a filter that passes multiple bands (for example, two bands of 500-600nm + 900-1800nm) obtained by multi-band coating on a transparent substrate, or it can be a single-band filter that passes a single band (such as 500-1800nm ​​or 900-1800nm ​​or 500-600nm).

[0072] In the third embodiment, the semiconductor cooling element 10' with a transparent substrate cold surface is generally circular. Its circumferential edge is clamped within the annular front shell 110, covering the large window at the front end of the housing 100, forming a large light-emitting surface, or mirror. The temperature of the transparent substrate cold surface 15 is controlled by a temperature sensor assembly 30. Similar to the above-mentioned embodiments, the tungsten or carbon filament light source beauty mirror 1000 of this embodiment includes a housing 100, a transparent substrate (semiconductor cooling element with a transparent substrate cold surface) 10 mounted therein, a filter 11, a heat sink 16, a tungsten or carbon filament light source 20, a reflector 21, a reflector heat sink 22, a temperature sensor assembly 30, a heat shield 40, a main control board 50, and a battery 60. The third embodiment has the same structure and configuration as the previous embodiments, as described above.

[0073] Referring to Figure 10 , the fourth embodiment of the present application shows a skin-beautifying mirror 1000, which features a makeup mode (serving as a makeup mirror) and a photonic skin-beautifying mode. This mirror differs from the third embodiment in that the filter 11 is formed on the surface of the transparent substrate cold surface 15 through an optical coating process, rather than being provided separately. For example, a filter coating is applied to the inner surface (facing the light source) of the transparent substrate cold surface 15. The transparent substrate cold surface 15 and the filter film form an integrated structure, thereby creating a transparent substrate semiconductor cooling element 10' with a built-in filtering function. Light generated by a tungsten or carbon filament light source 20 passes through the transparent substrate semiconductor cooling element 10', which incorporates the filter film, to produce light waves within a predetermined wavelength range that illuminate the skin. The transparent substrate semiconductor cooling element 10' with a built-in filtering function (filter film) can be a single-band or multi-band coating. For example, the transparent substrate semiconductor cooling element 10' with a built-in filtering function (filter film) has a filtering function that allows wavelengths above 760 nm to pass. Light generated by a light source passes through the transparent substrate semiconductor cooling element 10' with a filtering function (filter film), and the light wavelengths above 760 nm are irradiated on the skin surface. The fourth embodiment has the same structure and configuration as the previous embodiments, as can be seen in the previous embodiments.

[0074] 11-16 , the skin-beautifying mirror 1000 of the fifth embodiment of the present application has a makeup mode (as a makeup mirror) and a photon skin-beautifying mode. Referring to the structure of the first embodiment, this embodiment differs in that the filter 11 of the skin-beautifying mirror 1000 is detachable and replaceable. A protective ring 17 is provided on the outer cover of the transparent substrate 10. The protective ring 17 is tightly fitted around the outer edge of the transparent substrate 10 and then assembled as a whole onto the inner ring side of the front shell 110. A detachable mating structure such as a magnetic attraction, snap fastener, or spiral can be formed between the protective ring 17 and the front shell 110, so that the transparent substrate 10 can be detachably mounted on the front shell 110 via the protective ring 17. The entire surface of the transparent substrate 10 covers the front end of the rear shell 120, forming a large-area light-emitting surface. The filter 11 is detachably clamped onto the inner ring side of the front shell 110. In this embodiment, the optical filter 11 is replaced by removing the transparent substrate 10. To replace the optical filter 11, the transparent substrate 10 is first disassembled, the optical filter 11 is removed, and another optical filter 11 is installed. Finally, the transparent substrate 10, encased in a protective ring 17, is reinstalled into the front end of the housing. In this embodiment, the optical filter 11 is independently provided. The optical filter 11 can be optically coated on a transparent substrate to obtain filtering characteristics within a predetermined wavelength range. Alternatively, a filter obtained by other conventional methods can be used. The multiple filters 11 each have filtering characteristics of a different wavelength band, and different filters 11 can be switched to achieve different wavelength band treatments for different skin problems; for example, the filter 11 is a NIR filter, which can pass near-infrared light waves but not invisible light; a precision light filter can be used: it can pass a single wavelength band, such as 500-600nm or 500-650nm; a multi-wavelength filter can also be used: the same coating area can have two or more wavelength bands passing at the same time, for example, 500-600 and 900-1800nm ​​two wavelength bands passing, so that light waves of two or more wavelength bands are obtained to act on the skin.

[0075] The fifth embodiment of the tungsten or carbon filament light source beauty mirror 1000 includes a housing 100 and, mounted therein, a transparent substrate 10, a filter 11, a tungsten or carbon filament light source 20, a reflector 21, a reflector heat sink 22, a temperature sensor assembly 30, a heat shield 40, a main control board 50, and a battery 60. The housing 100 includes a front shell 110 and a rear shell 120 that interlock with each other. The transparent substrate 10 can be a solid transparent crystal, with a protective ring 17 positioned around its edge. This ring 17 is secured to the transparent substrate 10 through a tension fit and a mating structure of protrusions and grooves. The temperature of the transparent substrate (transparent crystal) 10 is controlled by the temperature sensor assembly 30. The solid transparent substrate 10 provides a large light-emitting surface. The filter 11 is disposed on the inner side of the transparent substrate 10 and is removably secured by the annular front shell 110 or the rear shell 120. For example, the filter 11 is attached to the inner side of the transparent substrate 10 and covers the light outlet of the reflector 21. The tungsten or carbon filament light source 20 is enclosed in the reflector 21. The light generated by the tungsten or carbon filament light source passes through the filter 11 and the transparent substrate 10 and acts on the skin. A heat sink 22 is provided on the back of the reflector. The fifth embodiment has the same structure and configuration as the previous embodiment.

[0076] 17-18 , the skin beauty mirror 1000 of the sixth embodiment of the present application has a beauty mode as a beauty mirror and a photon skin beauty mode. It is configured with a structure in which a replaceable filter 11 can be replaced by inserting and pulling the filter 11 on the side of the housing 100. Corresponding to the position of the filter 11 inside the housing 100, a filter insertion port 150 is correspondingly provided on any side of the housing 100. The filter 11 is fixed on the bracket 111. The shape of the filter 11 and the bracket 111 is adapted to the insertion port 150, and when inserted into the insertion port 150, the bracket 111 can protrude outside the insertion port 150 to facilitate the insertion and pulling of the filter 11. The filter 11 is provided independently. The filter 11 can obtain a filtering characteristic that allows a predetermined wavelength band to pass through by optically coating a transparent substrate. Multiple filters 11 each have a different wavelength band, and different filters 11 can be switched to achieve different wavelength band treatments for different skin problems. In this embodiment, the housing 100 is square, but not limited to a square shape. A window is provided at the front of the housing to accommodate the transparent substrate 10. The edge of the transparent substrate 10 snaps onto the edge of the window at the front of the housing 110, providing a large light-emitting surface. Inside the housing are mounted a filter 11, a tungsten or carbon filament light source 20, a reflector 21, a reflector heat sink 22, a temperature sensor assembly 30, a heat shield 40, a main control board 50, and a battery 60. For example, the filter 11 is attached to the inner side of the transparent substrate and covers the light outlet of the reflector 21. The tungsten or carbon filament light source 20 is sealed to the reflector 21. Light generated by the tungsten or carbon filament light source 20 passes through the filter 11 and the transparent substrate 10 before being applied to the skin. A heat sink 22 is provided on the back of the reflector. The temperature sensor assembly 30 and the main control board 50 control the surface temperature of the transparent substrate in contact with the skin. When the tungsten or carbon filament light source 20 illuminates the skin through the filter 11 and the transparent substrate (transparent crystal) 10, the temperature of the transparent substrate is detected by the temperature sensor assembly 30. The main control board 50 controls the power and on / off of the tungsten or carbon filament light source 20 to manage the temperature range and prevent burns to the skin caused by prolonged use. The transparent substrate 10 can be a solid piece of transparent crystal or the semiconductor cooling element 10' with the transparent substrate cold surface 15 of the above-mentioned embodiment. The sixth embodiment has the same structure and configuration as the previous embodiment, as referenced above.

[0077] Referring to Figures 19-23, the skin-beautifying mirror 1000 of the seventh embodiment of the present application has a makeup mode (as a makeup mirror), a photon skin-beautifying mode, and a radio frequency skin-beautifying mode. A radio frequency accessory head 80 is mounted on the front of the main body of the skin-beautifying mirror. The radio frequency accessory head 80 includes a radio frequency electrode 82. For example, the radio frequency accessory head 80 is connected to the main body of the skin-beautifying mirror by contact or pin / tab connection. The skin-beautifying mirror 1000 includes a housing 100 and, mounted therein, a transparent substrate 10, a filter 11, a tungsten or carbon filament light source 20, a reflector 21, a reflector heat sink 22, a temperature sensor assembly 30, a heat shield 40, a main control board 50, and a battery 60. The transparent substrate 10 can be a solid transparent crystal, with a protective ring 17 provided along its edge. The protective ring 17 can be secured to the transparent substrate 10 through a tension fit and a mating structure of protrusions and grooves. The solid transparent crystal provides a large light-emitting surface. The temperature of the transparent crystal is controlled by the temperature sensor assembly 30. The optical filter 11 is mounted on one side of the transparent crystal and is mounted within the annular front housing 110 or rear housing 120. For example, the optical filter 11 is bonded to the inner side of the transparent substrate (transparent crystal) 10 and covers the light outlet of the reflector 21, enclosing the tungsten or carbon filament light source 20 within the reflector 21. A heat sink 22 is located on the back of the reflector. A heat shield 40 separates the cavity within the rear housing 120 from the front and back. The main control board 50 and battery 60 are mounted within the cavity of the rear housing 120, which is covered by the heat shield 40.

[0078] The main control board 50 is used to control the operation of the skin beauty mirror 1000. In addition to the integrated control unit, the main control board 50 also includes related functional modules such as a DC power module and a light source control module. The tungsten or carbon filament light source 20 and the battery 60 are electrically connected to the main control board 50. The power interface 130 is electrically connected to the power module on the main control board 50 and is connected to an external power source via a power cord to provide power. The battery 60 can be omitted, and power can be directly supplied from the power interface.

[0079] A radio frequency control board may also be installed within the housing 100. The radio frequency control board includes functional modules such as a control module, a DC power module, and a radio frequency driver module. When the radio frequency control board is independently provided, it is electrically connected to the main control board 50, and the DC power module of the radio frequency control board is powered by a shunted power module on the main control board 50. In other embodiments, the radio frequency control board is integrated into the main control board 50, and corresponding functional modules such as the control module, DC power module, and radio frequency driver module are integrated into the main control board 50.

[0080] The RF accessory head 80 includes an electrode fixing frame 81 and one or more RF electrodes 82 mounted by the electrode fixing frame 81. The ends of each pair of RF electrodes 82 are provided with positive and negative electrodes 83, and the positive and negative electrodes 83 are electrically connected to the RF control board or the main control board 50 through wires 85. The RF accessory head 80 is detachably connected to the front end of the skin beauty mirror 1000, which can be plugged in, snapped together, or magnetically adsorbed. For example, a number of magnets 84 can also be installed on the fixing frame 81, and a number of magnets 84 are correspondingly installed in the front end of the shell of the skin beauty mirror, such as the front shell 110, so that magnetic adsorption is formed between the RF accessory head 80 and the skin beauty mirror. The overall shape of the fixing frame 81 is adapted to the shape of the window or transparent substrate 10 of the shell 100, and is assembled on the outside of the window or transparent substrate 10 of the shell 100. A mounting hole 810 is provided on the fixing frame 81, and the RF electrode 82 is adapted to the mounting hole 810 and embedded in the mounting hole 810. For example, a flange or protrusion is formed around the periphery of the fixing frame 81, and a gap or slot is formed between the front shell 110 and the edge of the transparent substrate 10. The flange or protrusion of the fixing frame 81 is inserted into the gap or slot between the front shell and the edge of the transparent substrate for plugging and mating, and the RF accessory head 80 can also be removed and disassembled. A notch is formed on the flange of the fixing frame 81 to allow the positive and negative poles 83 of the RF electrode to pass through the notch to electrically connect to the main control board or an independent RF control board inside the main body of the skin beauty mirror.

[0081] For example, the mounting bracket 81 is in the form of a disk (but not limited to a disk) that fits snugly within the circular transparent substrate and the annular front housing 110. A spiral mounting hole 810 is provided on the mounting bracket 81. A pair of spiral RF electrodes 82 are interlocked and clamped into the spiral mounting hole 810. Each end of the pair of RF electrodes 82 forms a pair of positive and negative electrodes 83, which are bent and inserted into the gap or through-hole between the edge of the transparent substrate 10 and the annular front housing 110. They are electrically connected to the main control board 50 (or RF control board) via wires 85 routed along the inner wall of the housing. The RF electrodes 82 can also be in the form of bars, columns, or any other suitable shape. They are installed in the mounting hole of the mounting bracket 81 to form RF electrode points that contact the skin. The RF electrodes 82 can overlap with the light-emitting surface or be positioned around the light-emitting surface. The RF control board or main control board 50 controls the DC power supply module to provide the voltage required for the corresponding gear to the RF drive module. The RF drive module converts the DC power supply voltage into a high-voltage sine wave through a step-up transformer and transmits it to the output control module. The output control module outputs RF current through the RF electrode 82 to act on the user's skin, performing RF treatment or RF beauty on the skin.

[0082] In the seventh embodiment, the transparent substrate 10 can be a whole transparent crystal or the semiconductor refrigeration element 10' of the above embodiment with the transparent substrate cold surface 15. The structure and configuration of this embodiment are the same as those of the above embodiment.

[0083] The various components of the skin beautification mirror 1000 of the above embodiments can be combined or replaced with each other to obtain skin beautification mirrors of different embodiments.

[0084] The skin-beautifying mirror 1000 of the present application uses a tungsten or carbon filament light source to illuminate the skin through a filter / membrane, then through a transparent substrate at a constant temperature. The light waves in different wavelength ranges act on the epidermis, basal layer, melanocytes, and dermis of the skin in a targeted manner to achieve the purpose of skin beautification. For example, the emitted light has a wavelength range of 500-600nm that acts on the epidermis of the human body, and the light waves in the 900-1800nm ​​range that act on the basal layer and melanocytes of the human body.

[0085] The skin beauty mirror in the embodiment of the present application realizes multiple uses in one device, a beauty mirror + a large-window beauty instrument, which greatly reduces the consumer's usage cost, usage time, and maintenance cost.

[0086] In the makeup mode of the skin-beautifying mirror of the present embodiment, the filter or filter film uses optical coating to create a mirror effect, resulting in a finer mirror surface than conventional mirrors using a spray coating process. Because the optical coating process produces a finer molecular structure than the spray coating process, the optically coated filter or the mirror formed by the transparent substrate with an integrated filter film in the present embodiment has higher clarity.

[0087] The skin beautification mode of the skin beautification mirror in the embodiment of the present application: the light-emitting surface is approximately the size of the front end surface of the skin beautification mirror (the entire mirror surface), which can achieve large-area whole-body skin beautification and is faster and more efficient to use.

[0088] The skin-beautifying mirror of the present invention uses a tungsten or carbon filament light source, a full-band light source with a wide spectral range. The filtered near-infrared light has a strong repair and activation effect on human skin, blood vessels, dermis, collagen, and elastic fibers. Using a tungsten or carbon filament light source and filters of different wavelengths, the mirror provides targeted skin beautification and repair. Therefore, the present invention's skin-beautifying mirror is more efficient, faster, and more convenient.

[0089] The skin-beautifying mirror of the embodiment of the present application has a filter that adopts a single-piece single-interval band type, a single-piece multi-interval band type, a multi-piece type, or a multi-partition single-piece type, or a transparent substrate (such as transparent crystal) coated integrated type; after filtering the full-spectrum light generated by the tungsten filament or carbon filament light source, it can obtain light in more bands, and make its light waves act on the skin epidermis, basal layer, melanocytes, and dermis tissue in a targeted manner to achieve the purpose of beauty and skin care.

[0090] The skin-beautifying mirror of the embodiment of the present application uses a temperature sensor to control the temperature of the transparent substrate and maintain a constant temperature of the transparent substrate; when the tungsten filament or carbon filament light source irradiates the skin through the filter / filter film and the transparent substrate, the temperature of the transparent substrate is detected by the temperature sensing device, and the power and switch of the tungsten filament or carbon filament light source are controlled by the main control board 50 to manage the temperature range, thereby avoiding burns to the skin due to long-term use.

[0091] The skin-beautifying mirror of the embodiment of the present application adopts active temperature control, and uses semiconductor refrigeration elements to control the temperature of the transparent substrate within a range.

[0092] The skin-beautifying mirror of the embodiment of the present application is assisted by radio frequency: for example, NIR + radio frequency, which can realize different light bands + radio frequency treatment.

[0093] The following embodiments of the present application describe the use of the skin-beautifying mirror:

[0094] When used as a makeup mirror, it can be held by hand or placed on a table;

[0095] When using a beauty model, the handheld instrument is used by placing the outer surface of its transparent substrate against the skin.

[0096] Although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application, and the scope of protection of the present application is defined by the appended claims and their equivalents.
