Example 1

As shown in fig. 1, the embodiment of the invention discloses an LED light therapy mask cover, which mainly combines optical beauty treatment with a mask, and performs optical beauty treatment while a user applies the mask. This LED phototherapy mask cover mainly includes:

the cover 100, includes: a first surface facing the human face and a second surface facing away from the human face, wherein the first surface of the mask body 100 is provided with fixing

parts

101 and 102 for fixing the light-permeable mask 500; the mask 500 herein is preferably a translucent or transparent mask through which light can be directly transmitted.

A plurality of LED point light sources 200, the LED point light sources 200 being discretely distributed on the cover body 100 and emitting light having a predetermined wavelength range;

a light diffusion layer 400 disposed on the first surface side of the cover body, for diffusing the LED light emitted from each of the LED point light sources 200, transmitting the LED light through the mask 500, and irradiating the LED light onto a human face;

the controller 600 independently controls each LED point light source and adjusts the light emitting power of each LED point light source, wherein when the face of a person is pasted with a facial mask and fixed by a fixing part, the controller 600 controls the LED point light sources in the corresponding area to irradiate with first power according to the acting time of the facial mask and the specified light treatment area on the face of the person; and when the acting time of the mask is longer than the acting time of the mask, controlling the LED point light source to irradiate with second power, wherein the first power is smaller than the second power. When facial light treatment is carried out, when a user applies the facial mask, the facial mask is irradiated at a first power, wherein the power value of the first power is lower than a second power, and the second power refers to the standard power (the power adopted when an optical beauty instrument is used for beautifying alone) of a point light source under normal irradiation. The main components of the facial mask are water and sodium hyaluronate, and the components inside the facial mask are slightly different according to the cosmetic requirements, so that the slight point light source irradiation can ensure that the cosmetic components of the facial mask can be well absorbed, and meanwhile, when the facial mask works at a first power, the optical cosmetic effect can be firstly achieved on the surface layer of the face. After the mask is applied for a proper time, the optical treatment of the facial skin problem can be continued because most of the cosmetic components of the mask are absorbed by the skin and then the facial irradiation is performed at the second power.

In addition, in order to ensure that the LED light treatment mask is stable when the face of a human face is subjected to light treatment, the LED light treatment mask is further provided with a fixing band 300 for fixing the mask on the head, and after the fixing band 300 is fixed, light of the point light source 200 can be stably irradiated on the face, so that a user can conveniently move freely when the LED light treatment mask is used.

In one embodiment, the wavelengths between two adjacent LED point light sources 300 are different. Here to treat more than one problem of the face optically with point light sources 300 of different wavelengths. For example, red light is used more (for beautifying and whitening, fading color spots and the like), but acne and the like exist sometimes, and proper blue light irradiation is needed, so that the LED point light source with the blue light wavelength can achieve a better effect in treatment.

In one embodiment, to achieve targeted and better results in light therapy, the controller of the embodiment of the invention controls the LED point light source emitting light of a first wavelength at a first time and controls the LED point light source emitting light of a second wavelength different from the first wavelength at a second time.

In a specific embodiment, the light diffusion layer comprises a plurality of flexible diffusion layers, and the flexible diffusion layers are used for diffusing light rays emitted by the LED point light sources with the first wavelength and the LED point light sources with the second wavelength.

In another embodiment, in order to distribute the light more uniformly on the face, in an embodiment of the present invention, the light path difference is increased so that the light reaches the light diffusion layer after having a longer transmission distance, the cover body 100 is a transparent cover, and the LED light therapy mask cover further includes: and the LED point light source 200 emits light towards the human face, and the light is reflected by the reflecting layer and then sequentially passes through the transparent cover 100, the light diffusion layer 400 and the mask 500 to enter the human face. Here, the light emitting direction of the point light source 200 is reversed, so that light is emitted away from the face, reaches the reflective layer, is reflected by the reflective layer, passes through the cover body 100, and then reaches the light diffusion layer 400. Therefore, the light can be fully mixed before entering the light reflection layer, and then the mixed light is diffused by the light diffusion layer to irradiate the face, so that the light is more uniform. The mask body can be made of the existing transparent or semitransparent mask material, such as collagen with good light transmittance.

Example 2

As shown in fig. 2 and 3, the light diffusion layer 400 and the cover 100 according to the embodiment of the present invention may both adopt a planar elastic thin layer structure. The outline shape of the light diffusion layer 400 may be the same as or similar to the shape of the cover body 100.

The controller 600 includes: the LED point light source comprises a control circuit board 601 and a power supply 602, wherein the power supply 602 supplies power to the control circuit board 601 and the LED point light source 200, and the control circuit board 601 is provided with a control circuit 70 and further comprises a communication module 60 for communicating with a mobile device 50 such as a mobile phone. The control circuit 70 controls the LED point

light sources

201, 202, 203, 204 to emit light through the communication interface 210 disposed on the cover 100, wherein the LED point

light sources

201, 202, 203, 204 may be point light sources with the same wavelength or point light sources with different wavelengths.

The control circuit 70 includes: one or more of a Processor, a Central Processing Unit (CPU), a single chip, an ARM, a Digital Signal Processor (DSP), an Application Specific Integrated Circuit (ASIC), a Field-Programmable Gate Array (FPGA), or other Programmable logic devices, discrete Gate or transistor logic devices, discrete hardware components, and the like.

In this embodiment, the LED point light source may emit light within a range of 360nm to 800nm, the controller 600 includes an LED light source band switching module, the controller 600 is further configured to receive a band selection instruction, and the LED light source band switching module switches a band of the light emitted by the LED light source to a correspondingly selected band according to the band selection instruction. When the LED light source is used, a user can select a wavelength band of LED light to be irradiated according to needs, the selection result is input to the controller 600 as a wavelength band selection instruction, and the LED light source wavelength band switching module in the controller 600 switches the wavelength band of light emitted by the light source according to the user's selection during irradiation.

When a user normally uses the cover body 100 to apply a transparent or semitransparent mask for beauty treatment, the controller 600 controls the LED point light source 200 to emit LED light of a preset wavelength range. The LED light is uniformly emitted toward one surface of the transparent or translucent mask 500 after passing through the light diffusion layer 400, and then irradiated on the user's face through the transparent or translucent mask, so that the user performs beauty treatment by applying the transparent or translucent mask while using light.

When the LED light treatment mask cover of the embodiment is used for beautifying, a user only needs to fix the face on one side of the light diffusion layer facing the face of a person and then pastes the face, the operation is very convenient, then the LED point light source is controlled by the mobile terminal to emit the illumination within the preset wavelength range at the first power for beautifying, and when the components of the mask are absorbed by the face according to the preset time, the illumination within the preset wavelength range is emitted at the second power for beautifying. Therefore, the user does not need to extract excessive time to specially perform the light beauty treatment. The LED light treatment mask cover is used for illuminating and beautifying when a user pastes a mask, and the cover body is arranged like a human mask and can be used for reading books, watching television, using a mobile phone and the like, so that the user is not delayed to entertain other entertainment or read books and study while beautifying.

As shown in fig. 3, in this embodiment, the controller 600 further includes a communication module 60, the controller 600 receives a light-emitting control parameter sent by the mobile terminal 50 through the communication module 60, the controller 600 controls the LED light source to emit light according to the light-emitting parameter, and the light-emitting control parameter is generated by the mobile terminal 50 according to the skin beauty parameter of the user. Wherein the mobile terminal 50 may be a mobile phone, a tablet computer, a specially configured remote controller, etc. The APP software can be installed in the mobile phone. The user inputs skin beauty parameters such as time for beauty, wave bands of LED light adopted during beauty, irradiation time of LED light with different wave bands, irradiation power and the like into the mobile phone through the APP software. The user can also input beauty modes such as a whitening mode, a wrinkle removing mode, a skin smoothness improving mode and the like through the APP, and the APP selects corresponding wave bands of LED light, irradiation time of the LED light with different wave bands, irradiation dose and the like according to different modes. The APP software generates corresponding light emitting control parameters according to the skin beauty parameters, and the controller 600 controls the LED point light source to emit light according to the light emitting control parameters.

The embodiment of the present invention sets the LED light source and the controller 600 to be separable from each other. Therefore, when the user uses the LED light treatment mask cover of the embodiment, the user only needs to cover the LED light treatment mask cover with the upper mask or cover the LED light treatment mask on the face of the user after the mask is pasted, the load of the face of the user can be reduced, and the user experience is improved.

In an embodiment of the present invention, the fixing band 300 of the LED light therapy mask cover may be replaced by a bracket, wherein the bracket may be a linear bracket or a cross bracket to fix the LED light therapy mask cover. When the linear support is adopted, the length direction of the support is parallel to the arrangement direction of human eyes. When the light diffusion layer 400 and the mask body 100 are placed on the human face, the support spans the bridge of the nose of the face. The part of the bracket corresponding to the bridge of the nose of the human body is provided with a bending part matched with the shape of the bridge of the nose, so that the bracket can be well attached to the face of the human body. The straight-line-shaped bracket has simple structure and relatively light weight. When the cross-shaped support is adopted, the support comprises a first support strip and a second support strip which are perpendicular to each other, and the length direction of the first support strip is parallel to the arrangement direction of human eyes. When the light diffusion layer 400 and the mask body 100 are placed on the human face, the first support struts cross the bridge of the nose of the face. The part of the first supporting strip corresponding to the bridge of the nose of the human body is provided with a bending part matched with the shape of the bridge of the nose, so that the supporting strip can be well attached to the face of the human body.

In a variable embodiment of the invention, the face can be pre-irradiated before the mask is applied, wherein the pre-irradiation is mainly to sterilize the face, for example, a low-power ultraviolet LED point light source is used for irradiating the face to remove bacteria on the face, and then the mask is applied to enter a stage of combining the LED point light source and the mask for beauty.

Of course, since the heat from the LED point source helps absorb the mask components when illuminated at the first power, the time to apply the mask may be a lower time limit of the product instructions for the mask, such as 15 minutes to 30 minutes as suggested by the product instructions, which may reduce the time to 15 minutes. The face is then irradiated at a second power, shortening the time of the light treatment.

Application examples

On the basis of the above embodiments 1 to 3, a specific application of the present invention using the above intelligent control method will be described.

The step S10 may specifically include the following steps:

s11: when the mask is applied, acquiring a light-emitting control parameter;

the light emission control parameters include, but are not limited to, light emission band, light emission power, light emission time, pulse frequency of pulsed light, and duty ratio of pulsed light. Here, the user may use the mobile terminal to select a beauty mode or set a lighting control parameter on an interface of the APP software.

S12: generating a light emitting driving signal according to the light emitting control parameter;

the step generates a driving signal for driving the LED point light source to emit light according to the light emitting parameters, wherein the driving signal can be a voltage signal and/or a current signal.

S13: and driving a light source to irradiate the human face with LED light in a preset wavelength range according to the light-emitting driving signal.

One specific irradiation method is to sequentially perform the following steps:

s131: firstly, irradiating the human face by using LED light with the wavelength range of 577 nm-593 nm for a first preset time t 10; that is, irradiation with yellow light can dilate capillaries, etc., which helps the skin to absorb the components of the mask. In addition, yellow light can also enhance skin resistance and improve skin erythema and rash.

The step is to irradiate the skin with 577 nm-593 nm LED light, the wavelength range belongs to yellow light, the capillary circulation of the skin superficial layer position can be effectively improved, the cell activity is improved, the action depth of the light of the wave band can reach 0.5-2 mm below the skin surface, and the skin has a good effect on the absorption of the mask components.

S132: then irradiating the human face with the LED light with the wavelength range of 628 nm-700 nm for a second preset time t20 with the first illumination dose; the wavelength range belongs to red light, the wavelength of the red light is longer, the energy is relatively small, and when the mask is applied, a large amount of heat can not be generated to cause evaporation of facial components. In the step, after the cells of the yellow light at the skin shallow layer position in the step S131 are activated, the human face is continuously irradiated by the red light LED light with the wavelength range of 628 nm-700 nm, so that after mitochondria in the cells absorb the light of the wave band, the activities of various enzymes related to energy metabolism such as catalase, superoxide dismutase (SOD) and the like in the mitochondria are enhanced, the synthesis and supply of Adenosine Triphosphate (ATP) are accelerated and increased, the energy supply for tissue cells is increased, the cell activity is further improved, the clearing process of organism metabolism and toxic metabolites in vivo is accelerated, and the irradiated skin is smoother. And the action depth of the wave band light is deeper than that of the previous step, and can reach 2-2.5 mm. Because the facial mask is still in the application time range, the first illumination dose is not suitable to be too large so as to avoid the problem that facial mask components are evaporated and not absorbed by human faces.

S133: then irradiating the human face for a third preset time t30 by using LED light with the wavelength range of 628-700 nm and a second illumination dose which is larger than the first illumination dose; the facial mask component can be absorbed continuously, and can be properly enhanced on the basis of the first light dose, and the action depth on the facial skin is gradually deepened. The step uses the LED light with the wavelength range of 628 nm-700 nm to continuously irradiate the face of the human body with the second irradiation dose, so that the red light can deeply irradiate the subcutaneous blood vessels, the microcirculation of the blood vessels of the skin is increased, and the erythema, the pigment and the wrinkle of the skin can be reduced. With the lengthening of the time of acting on the skin, the penetration depth of the light rays at the wave band is further deepened and can reach 2-3 mm.

S134: and then irradiating the face of the person for a fourth preset time t40 with LED light with the wavelength range of 628-700 nm in a third light dose, wherein the third light dose is greater than the second light dose so as to further deepen the depth of action on the skin.

After the previous step of irradiation is finished, the step continuously irradiates the face of the person with LED light with the wavelength range of 628nm to 700nm at a third irradiation dose, and the penetration depth of the light rays in the wave band can be further deepened along with the lengthening of the irradiation time and the activation of the surface skin, and can reach 3mm to 6 mm. In this embodiment, the skin of the face is irradiated in the order that the wavelength band of the irradiation light is gradually increased, and the light penetration is gradually increased, so that the skin cell activity can be improved layer by layer from the shallow to the deep.

In addition, the time length relationship in this embodiment may be combined with the mask component absorption progress, generally, in the early stage, due to the fact that the capillary vessels and the like of the facial skin are just expanded, the absorption of the mask component will be gradually accelerated, and as time goes on, after the mask component is absorbed by the skin, the facial skin absorbs more moisture and the like, so that the absorption of the mask component will be slowed down later, and therefore, the time length of each time interval may be adjusted according to the total light treatment time length selected by the user in the aspect of the illumination time, so as to obtain the better effect of the face on the mask component absorption and the light treatment within the user preset total time length. For this reason, yellow light can be applied for a shorter time, while red light is applied for a longer time, since the effect of red light on the improvement of the facial skin is more pronounced. Illustrative examples of the invention are: let t10 be 2t, t20 be 1t to 1.25t, t30 be 1.25t to 1.5t, t40 be 2t to 3t, and t is a positive real number. By adopting the mode, the facial mask absorption and the light treatment effect are considered under the condition that the LED light of each wave band outputs the first power, the facial mask components are fully absorbed in the front time, the illumination dose is increased at the back, and the light treatment is carried out towards the deep part of the skin of the human face.

According to some papers and documents, the red light wavelength can be further segmented to be irradiated, the effect of the wavelength of the fine segments in the red light wavelength range on the facial skin is slightly different, and the following irradiation modes can be obtained by further improving the penetration effect after the wavelength is larger by considering the penetration of the red light in the application embodiment of the invention and taking the larger wavelength into consideration:
