Description

Light therapy instrument and control method of light therapy instrument

[0001] The present application claims priority to the Chinese patent application No. 202410441104.X, filed on April 12, 2024, with the Chinese Patent Office, the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the technical field of cosmetic instruments, for example to a light therapy instrument and a control method of the light therapy instrument. BACKGROUND

[0003] Currently, different wavelengths of light have different light therapy effects on the human body. For example, inhibiting bacteria, promoting or inhibiting melanin regeneration, promoting collagen regeneration, etc. In recent years, light therapy cosmetic instruments based on different wavelengths have also been increasingly concerned by people. Light therapy generally refers to physical treatment using ultraviolet rays, infrared rays, visible light, laser, etc.

[0004] Referring to the skin tissue structure in the related art, the skin tissue is generally composed of an epidermis layer, a dermis layer and a subcutaneous tissue, and the epidermis layer has a basal layer, and melanin exists in the basal layer. When the melanin in the basal layer is more, the skin is dull and has no luster, and when the melanin in the basal layer is less, the skin is relatively fair. In addition, the deposition of local melanin will form spots such as color spots. In addition, the dermis layer contains collagen, and when the collagen in the dermis layer is lost more, the skin will produce wrinkles.

[0005] In the related art, although the skin can be irradiated by blue light 420 nanometers (nm) to achieve the effect of inhibiting bacteria, the blue light has the effect of promoting the growth of melanin in the epidermis layer, which is easy to cause the skin to become darker. Although the skin can be irradiated by red light 580 nm to reach the epidermis layer of the skin to inhibit the production of melanin, thereby achieving the effect of whitening, the light of this wavelength is easily absorbed by melanin and water in the epidermis layer and cannot penetrate the epidermis layer to enter the dermis layer, thereby achieving the effect of anti-wrinkles.

[0060] The embodiments of the present application will be described below with reference to the accompanying drawings. The embodiments described are some of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of the present application.

[0061] The terms "first", "second", and the like in the description and the claims of the present application and the above-described drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in other than the order illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.

[0062] FIG. 1 is a structural schematic diagram of a light therapy instrument according to an embodiment of the present application. As shown in FIG. 1, the light therapy instrument includes a main body structure 100 and a plurality of light emitting units 200 arranged on the main body structure 100.

[0063] The light emitting units 200 can emit light of at least one of a first wavelength range of 590 nm-850 nm and a second wavelength range of 1072±15 nm. The light emitted by the light emitting units 200 can act on a skin area of a user.

[0064] The main body structure 100 can be a frame structure of the light therapy instrument except the light emitting unit 200, such as a mask-like main body structure of a facial light therapy instrument, or a hand-like main body structure of a hand light therapy instrument. The light emitting unit 200 is arranged on the main body structure 100, and can emit light under the control of the related controller. The light emitting unit 200 can be one of a light emitting diode (LED) chip, a mini light emitting diode (mini-LED), or a micro light emitting diode (micro-LED), or a laser light emitting part, and the light emitting unit 200 capable of emitting light in the above-mentioned wavelength range and wavelength value is within the protection scope of the present application. When the light emitting unit 200 is an LED chip, a shell 300 encapsulating the light emitting unit 200 can also be arranged on the main body structure 100, and the LED chip can be a single-color LED or a multi-color LED. The shell 300 can guide the light emitted by the light emitting unit 200, and the inner wall of the shell 300 can be provided with a reflective film to reflect the light emitted by the light emitting unit 200, for example. When a user uses it, the side surface of the main body structure 100 on which the light emitting unit 200 is arranged faces the user's skin, the light emitting unit 200 emits light under the control of the controller, and the shell 300 guides the light to the user's skin to act on the skin.

[0065] It should be noted that the light emitting unit 200 can emit light in the first wavelength range or the second wavelength range, or the light emitting unit 200 can emit light in the first wavelength range and the second wavelength range, wherein the first wavelength range is 590-850 nm, and the second wavelength range is 1072±15 nm. When the light emitting unit 200 can emit light of multiple wavelengths, and the LED chip is a single-color LED, the light emitting unit 200 can include multiple LED chips. Alternatively, multiple mini-LEDs or multiple micro-LEDs or multiple laser light emitting parts can also be included to emit light of multiple wavelengths.

[0066] Fig. 2 is a diagram showing the relationship between the wavelength of the light emitted by the light emitting unit of the light therapy instrument and the absorption coefficient, and Fig. 3 is a diagram showing the relationship between the wavelength of the light emitted by the light emitting unit of the light therapy instrument and the water transmittance. As shown in Figs. 2 and 3, the light in the first wavelength range of 590-850 nm belongs to the near-infrared band range. The light in this band range can promote cell proliferation based on the cytochrome c oxidase excitation principle. Moreover, the longer the wavelength of the light in this band range, the less the melanin and hemoglobin absorb the light. The shorter the wavelength of the light in this band range, the more the melanin and hemoglobin absorb the light. In addition, for the first wavelength range, the longer the wavelength, the higher the water transmittance of the light in this band range, and the shorter the wavelength, the lower the water transmittance of the light in this band range. Thus, the light in the first wavelength range can basically reach the epidermis of the user. Moreover, the light with a shorter wavelength, such as light close to 590 nm, can be absorbed by water and cannot reach the dermis, and the light with a longer wavelength, such as light close to 850 nm, can be transmitted by water and reach the dermis. Thus, the closer the wavelength of the light in this band range to 590 nm, the higher the absorption coefficient of the melanin for the light in this band range, the more the light acts on the melanin, the more the production of melanin is inhibited, the better the whitening effect, and the closer the wavelength to 850 nm, the lower the absorption coefficient of the melanin for the light in this band range, the more the light is transmitted, and finally the light can act on the dermis to stimulate the regeneration of collagen in the dermis and achieve a certain anti-wrinkle effect.

[0067] The light in the second wavelength range of 1072±15 nm (i.e., 1057-1087 nm) belongs to the infrared band range. The light in this band range can stimulate the regeneration of collagen in the dermis based on the principle of regulating capsaicin channels. Since the melanin, hemoglobin, and water have high transmittance for the light with a wavelength of 1057-1087 nm (as shown in Fig. 3, the water transmittance is about 93%), the light in this band range can pass through the melanin and hemoglobin in the epidermis and reach the dermis without being absorbed by the water in the dermis, thereby stimulating the regeneration of collagen in the dermis and achieving an anti-wrinkle effect. Thus, when the light emitting unit 200 emits light in the first wavelength range, it mainly acts on the boundary between the epidermis and the dermis, and the whitening effect is dominant, and the anti-wrinkle effect is auxiliary. When the light emitting unit 200 emits light in the second wavelength range, it mainly acts on the dermis, and the anti-wrinkle effect is dominant, and the whitening effect is auxiliary. When the light emitting unit 200 emits light in both the first wavelength range and the second wavelength range, since both belong to the infrared band range, they are based on the principle of inhibiting melanin and stimulating the regeneration of collagen, and the light in the two bands will not have opposite and canceling effects, but will have a superimposed effect, acting on the epidermis and the dermis at the same time, so that the whitening and anti-wrinkle effects are both optimal.

[0068] In some embodiments, when the light emitting unit is capable of emitting light in the second wavelength range, the wavelength of the light emitted by the light emitting unit 200 is one of 1064 nm, 1065 nm, 1067 nm, 1070 nm, 1071 nm, 1072 nm, 1073 nm, or 1074 nm.

[0069] As can be seen from FIG. 3, when the wavelength of the light emitted by the light emitting unit 200 is any one of 1064 nm, 1065 nm, 1067 nm, 1070 nm, 1071 nm, 1072 nm, 1073 nm, or 1074 nm, the transmittance of water is at or near the peak. When the wavelength of the light emitted by the light emitting unit 200 is 1072 nm, the transmittance of water is at the peak. As a result of the effect on the dermis layer, the best wrinkle removal effect can be achieved.

[0070] In some embodiments, when the light emitting unit 200 is capable of emitting light in the first wavelength range, the wavelength of the light emitted by the light emitting unit 200 is in at least one of the ranges of 590 nm-620 nm, 620 nm-640 nm, 650 nm-670 nm, 740 nm-760 nm, or 820 nm-860 nm.

[0071] When deoxyribonucleic acid (DNA) or ribonucleic acid (RNA) in cells is stimulated, the peaks appear in these wave bands, and thus, setting the light emitting unit 200 to emit light in the corresponding wave band can better stimulate cells and achieve better results.

[0072] In some embodiments, when the light emitting unit 200 is capable of emitting light in the 590 nm-620 nm wavelength range, the wavelength of the light emitted by the light emitting unit 200 is one of 606 nm, 610 nm, or 616 nm.

[0073] When the wavelength of the light emitted by the light emitting unit 200 is 606 nm, a peak appears when DNA in cells is stimulated, and when the wavelength of the light emitted by the light emitting unit 200 is 616 nm, a peak appears when RNA in cells is stimulated. When the wavelength of the light emitted by the light emitting unit 200 is 610 nm, the working condition of the existing LED lamp can be met, the light emitting unit 200 is easy to prepare, and the wavelength is between 606 nm and 616 nm, which can take into account the effects achieved by 606 nm and 616 nm.

[0074] In some embodiments, when the light emitting unit 200 is capable of emitting light in the 620 nm-640 nm wavelength range, the wavelength of the light emitted by the light emitting unit 200 is one of 624 nm, 630 nm, or 633 nm.

When the wavelength of the light emitted by the light-emitting unit 200 is at 630 nm, the working condition of the existing LED lamp can be met, the light-emitting unit 200 is easy to prepare, and the wavelength is between 624 nm and 633 nm, which can take into account the effects that can be achieved at 624 nm and 633 nm.

[0076] In some embodiments, when the light-emitting unit 200 can emit light in the wavelength range of 650 nm-670 nm, the wavelength of the light emitted by the light-emitting unit 200 is 660 nm or 668 nm.

[0077] When the wavelength of the light emitted by the light-emitting unit 200 is at 668 nm, a peak appears when stimulating cell RNA. When the wavelength of the light emitted by the light-emitting unit 200 is at 660 nm, the working condition of the existing LED lamp can be met, the light-emitting unit 200 is easy to prepare, and the wavelength is near 668 nm, which can take into account the effects that can be achieved at 668 nm.

[0078] In some embodiments, when the light-emitting unit 200 can emit light in the wavelength range of 740 nm-760 nm, the wavelength of the light emitted by the light-emitting unit 200 is 751 nm.

[0079] When the wavelength of the light emitted by the light-emitting unit 200 is at 751 nm, a peak appears when stimulating cell DNA.

[0080] In some embodiments, when the light-emitting unit 200 can emit light in the wavelength range of 820 nm-860 nm, the wavelength of the light emitted by the light-emitting unit 200 is one of 830 nm, 831 nm, 846 nm, or 850 nm.

[0081] When the wavelength of the light emitted by the light-emitting unit 200 is at 831 nm, a peak appears when stimulating cell DNA, and when the wavelength of the light emitted by the light-emitting unit 200 is at 846 nm, a peak appears when stimulating cell DNA. When the wavelength of the light emitted by the light-emitting unit 200 is at 830 nm, the working condition of the existing LED lamp can be met, the light-emitting unit 200 is easy to prepare, and the wavelength is near 831 nm, which can take into account the effects that can be achieved at 831 nm. When the wavelength of the light emitted by the light-emitting unit 200 is at 850 nm, the working condition of the existing LED lamp can be met, the light-emitting unit 200 is easy to prepare, and the wavelength is near 846 nm, which can take into account the effects that can be achieved at 846 nm.

[0082] In some embodiments, the light emitting unit 200 can simultaneously emit light of one of 610 nm, 630 nm or 660 nm in the first wavelength range, and light in the second wavelength range. In some embodiments, the light in the second wavelength range can have a wavelength of 1072 nm.

[0083] When the light emitting unit 200 simultaneously emits light of 610 nm and light in the second wavelength range, both the stimulation effect on cell RNA and DNA and the anti-wrinkle effect of the second wavelength range can be achieved; when the light emitting unit 200 simultaneously emits light of 630 nm and light in the second wavelength range, both the stimulation effect on cell DNA and the anti-wrinkle effect of the second wavelength range can be achieved; when the light emitting unit 200 simultaneously emits light of 660 nm and light in the second wavelength range, both the stimulation effect on cell RNA and the anti-wrinkle effect of the second wavelength range can be achieved; and thus, whitening and anti-wrinkle can be simultaneously performed.

[0084] It should be noted that, since the light of one of 610 nm, 630 nm or 660 nm belongs to the visible light band, the user can visually perceive the emission of light when using the light therapy device.

[0085] In some embodiments, the combination of light emitted by the light emitting unit 200 in this embodiment can be one of 610 nm+1072 nm, 630 nm+1072 nm or 660 nm+1072 nm.

[0097] In some embodiments, the combination of light emitted by the light emitting unit 200 in this embodiment can be one of 610 nm+630 nm+660 nm+830 nm+1072 nm, or 610 nm+630 nm+660 nm+850 nm+1072 nm. Among them, the light in the first wavelength range can also be other point values in addition to the above point values, and the light in the second wavelength range can also be other point values in addition to the above point values.

[0098] In some embodiments, the light emitting unit 200 can emit one of 830 nm or 850 nm, and five wavelengths of light of 610 nm, 630 nm, 660 nm and 1072 nm. Better whitening and wrinkle removal effects can be achieved.

[0099] In some embodiments, a plurality of light emitting units 200 are uniformly distributed on the main body structure 100, and each light emitting unit 200 can simultaneously emit light in the first wavelength range and the second wavelength range.

[0100] It can be understood that a plurality of light emitting units 200 are distributed on the main body structure 100, and each light emitting unit 200 can simultaneously emit light in two wavelength ranges, so that the skin range covered by the main body structure 100 can simultaneously achieve the effects of whitening and wrinkle removal.

[0101] Exemplarily, each light emitting unit 200 can emit light of one combination of 610nm+1072nm, 630nm+1072nm, 660nm+1072nm, 610nm+830nm+1072nm, 630nm+830nm+1072nm, 660nm+830nm+1072nm, 610nm+850nm+1072nm, 630nm+850nm+1072nm, 660nm+850nm+1072nm, 610nm+660nm+830nm+1072nm, 630nm+660nm+830nm+1072nm, 610nm+630nm+830nm+1072nm, 610nm+660nm+850nm+1072nm, 630nm+660nm+850nm+1072nm, 610nm+630nm+850nm+1072nm, 610nm+630nm+660nm+830nm+1072nm, or 610nm+630nm+660nm+850nm+1072nm. Among them, the light in the first wavelength range can also be other point values in addition to the above point values, and the light in the second wavelength range can also be other point values in addition to the above point values.

[0102] In some embodiments, the plurality of light emitting units 200 are uniformly distributed on the main body structure 100, the main body structure 100 comprises a first area and a second area; the light emitting unit 200 capable of emitting light in the second wavelength range is arranged in the first area, wherein the degree of wrinkles on the skin of the user corresponding to the first area is greater than the degree of wrinkles on the skin of the user corresponding to the second area.

[0103] In some embodiments, the regions on the main structure 100 corresponding to regions where the user's skin has more wrinkles (such as the corners of the eyes, the corners of the mouth, etc.) can be arranged with more rows of light emitting units 200 capable of emitting light in the second wavelength range. In one embodiment, after arranging a plurality of light emitting units 200 capable of emitting light in the first wavelength range and the second wavelength range simultaneously on the main structure 100 uniformly, the regions such as the corners of the eyes, the corners of the mouth, etc. can be increased in density of light emitting units 200 capable of emitting light in the second wavelength range by adding light emitting units 200 capable of emitting light in the second wavelength range only. In another embodiment, in order to save costs, light emitting units 200 capable of emitting light in the first wavelength range and the second wavelength range simultaneously can be arranged only in regions with more wrinkles, and light emitting units 200 capable of emitting light in the first wavelength range only can be arranged in other regions. Among them, the light emitting units 200 capable of emitting light in the first wavelength range and the second wavelength range simultaneously are arranged, and the wavelength combination can be one of 610nm+1072nm, 630nm+1072nm, 660nm+1072nm, 610nm+830nm+1072nm, 630nm+830nm+1072nm, 660nm+830nm+1072nm, 610nm+850nm+1072nm, 630nm+850nm+1072nm, 660nm+850nm+1072nm, 610nm+660nm+830nm+1072nm, 630nm+660nm+830nm+1072nm, 610nm+630nm+830nm+1072nm, 610nm+660nm+850nm+1072nm, 630nm+660nm+850nm+1072nm, 610nm+630nm+850nm+1072nm, 610nm+630nm+660nm+830nm+1072nm or 610nm+630nm+660nm+850nm+1072nm. Among them, the light in the first wavelength range can also be other point values in addition to the above point values, and the light in the second wavelength range can also be other point values in addition to the above point values.

[0104] The light-emitting unit 200 emitting light in a single first wavelength range, and the wavelength combination can be one of 610 nm, 630 nm, 660 nm, 610 nm+830 nm, 630 nm+830 nm, 660 nm+830 nm, 610 nm+850 nm, 630 nm+850 nm, 660 nm+850 nm, 610 nm+660 nm+830 nm, 630 nm+660 nm+830 nm, 610 nm+630 nm+830 nm, 610 nm+660 nm+850 nm, 630 nm+660 nm+850 nm, 610 nm+630 nm+850 nm, 610 nm+630 nm+660 nm+830 nm, or 610 nm+630 nm+660 nm+850 nm. The selection can be made according to actual conditions. Among them, the light in the first wavelength range can also be other point values in addition to the above point values, and the light in the second wavelength range can also be other point values in addition to the above point values.

[0105] It should be noted that the degree of wrinkles can be evaluated by a wrinkle parameter, such as by an image collector to capture a skin area image and perform corresponding analysis, the deeper the wrinkle depth and / or the more the number of wrinkles, the more wrinkles are likely to be.

[0106] In some embodiments, the plurality of light-emitting units 200 are uniformly distributed on the main body structure 100, the main body structure 100 comprises a third region and a fourth region; the light-emitting unit 200 capable of emitting light in a first wavelength range is arranged in the third region; wherein the third region and the fourth region have a corresponding relationship as follows: the whitening degree of the skin of the user corresponding to the third region is lower than the whitening degree of the skin of the user corresponding to the fourth region, and the spot degree of the skin of the user corresponding to the third region is higher than the spot degree of the skin of the user corresponding to the fourth region.

[0107] Referring to the skin tissue structure in the related art, the skin tissue includes, from shallow to deep, an epidermis layer, a dermis layer, and a subcutaneous tissue, etc. In this application, the 1072±15 nm wavelength mainly hits the deep part of the dermis layer, and can remove wrinkles. If the cause of some spots of the user is in the deep part of the skin, the 1072±15 nm wavelength has a good spot lightening effect; but the wavelength of 590-850 nm can also hit the dermis layer, and the depth of the dermis layer hit by the wavelength of 590-850 nm is shallower than that hit by the wavelength of 1072±15 nm, so the wavelength of 1072±15 nm is more beneficial to removing wrinkles; in the melanin layer, the effect of the light of the wavelength of 590-850 nm is more than that of the light of the wavelength of 1072±15 nm, that is, the light of the wavelength of 590-850 nm is more beneficial to whitening and / or lightening spots.

[0108] In order to save costs, the light emitting units 200 capable of emitting the first wavelength range can be arranged in more rows in the area of the main body structure 100 corresponding to the area with more skin color spots of the user, such as the cheek. In an embodiment, after the plurality of light emitting units 200 capable of simultaneously emitting the first wavelength and the second wavelength range are uniformly arranged on the main body structure 100, the light emitting units 200 capable of emitting the first wavelength range can be added in the areas such as the cheek and forehead to increase the density of the light emitting units 200 capable of emitting the first wavelength range. In another embodiment, in order to save costs, the light emitting units 200 capable of simultaneously emitting the first wavelength range and the second wavelength range can be arranged only in the area with more wrinkles, and the light emitting units 200 capable of emitting the first wavelength range can be arranged in the areas such as the cheek and forehead in a concentrated manner, and the arrangement density of the areas such as the cheek and forehead is greater than that of other areas.

[0109] In some embodiments, the light emitting units 200 capable of simultaneously emitting the first wavelength and the second wavelength range are arranged, and the wavelength combination can be one of 610nm+1072nm, 630nm+1072nm, 660nm+1072nm, 610nm+830nm+1072nm, 630nm+830nm+1072nm, 660nm+830nm+1072nm, 610nm+850nm+1072nm, 630nm+850nm+1072nm, 660nm+850nm+1072nm, 610nm+660nm+830nm+1072nm, 630nm+660nm+830nm+1072nm, 610nm+630nm+830nm+1072nm, 610nm+660nm+850nm+1072nm, 630nm+660nm+850nm+1072nm, 610nm+630nm+850nm+1072nm, 610nm+630nm+660nm+830nm+1072nm, or 610nm+630nm+660nm+850nm+1072nm. Among them, the light in the first wavelength range can also be other point values in addition to the above point values, and the light in the second wavelength range can also be other point values in addition to the above point values.

[0110] The light-emitting unit 200 of the single-emission first wavelength range can have a wavelength combination of one of 610 nm, 630 nm, 660 nm, 610 nm+830 nm, 630 nm+830 nm, 660 nm+830 nm, 610 nm+850 nm, 630 nm+850 nm, 660 nm+850 nm, 610 nm+660 nm+830 nm, 630 nm+660 nm+830 nm, 610 nm+630 nm+830 nm, 610 nm+660 nm+850 nm, 630 nm+660 nm+850 nm, 610 nm+630 nm+850 nm, 610 nm+630 nm+660 nm+830 nm, or 610 nm+630 nm+660 nm+850 nm. The selection can be made according to actual conditions. The light in the first wavelength range can also be other point values in addition to the above point values, and the light in the second wavelength range can also be other point values in addition to the above point values.

[0111] It should be noted that the degree of spots can be evaluated by the white parameter, such as testing the skin by a skin melanin tester. The more melanin, the more spots on the skin, the higher the degree of spots, and the lower the degree of whitening. The degree of whitening can be determined by a skin color sensor, compared with the color value, to obtain the degree of whitening. The darker the color value, the darker the skin, and the lower the degree of whitening.

[0118] Fig. 8 is a flowchart of a control method of a light therapy instrument according to an embodiment of the present application. The control device of the light therapy instrument includes the light therapy instrument according to any embodiment of the present application, and further includes a collection sensor and a controller. As shown in Fig. 8, the control method includes the following steps:

[0121] S103, adjusting at least one parameter of an opening number, an irradiation intensity, or an irradiation time of a light emitting unit of a region corresponding to the current skin area on the light therapy instrument according to the wrinkle degree.

[0122] In some embodiments, the controller can be configured to store data such as the wrinkle parameter and the wrinkle degree of the current skin area.

[0123] The wrinkle degree can be evaluated by a wrinkle parameter, such as by taking an image of a skin area by an image collector (collection sensor) and performing corresponding analysis, the deeper the wrinkle depth and / or the more the number of wrinkles, the more wrinkles are likely. The light therapy instrument can obtain the wrinkle degree of the skin through the parameters collected by the collection sensor, if the wrinkle degree is large, the number of openings can be large, the irradiation intensity needs to be strong, and the irradiation time needs to be long. If the wrinkle degree is small, the number of openings can be small, the irradiation intensity needs to be weak, and the irradiation time needs to be short.

[0124] In some embodiments, adjusting at least one parameter of the number of openings, the irradiation intensity, or the irradiation time of the light-emitting units corresponding to the current skin area on the light therapy instrument according to the wrinkle degree comprises:

[0127] The irradiation time of the light-emitting units capable of emitting the second wavelength range is positively correlated with the wrinkle degree.

[0128] When the irradiation intensity and the irradiation time of each light-emitting unit capable of emitting the second wavelength range are the same, and the adjusted parameter is the number of openings, when the wrinkle degree is less than a first wrinkle degree, control the first number of light-emitting units capable of emitting the second wavelength range to be lit; when the wrinkle degree is greater than the first wrinkle degree and less than a second wrinkle degree, control the second number of light-emitting units capable of emitting the second wavelength range to be lit; when the wrinkle degree is greater than the second wrinkle degree, control the third number of light-emitting units capable of emitting the second wavelength range to be lit; wherein the first wrinkle degree is less than the second wrinkle degree. The first number is less than the second number, and the second number is less than the third number.

[0129] When the number of openings of the light-emitting units capable of emitting the second wavelength range is all, and the irradiation time of each light-emitting unit capable of emitting the second wavelength range is the same, and the adjusted parameter is the irradiation intensity, when the wrinkle degree is less than a first wrinkle degree, control the irradiation intensity of the number of openings of the light-emitting units capable of emitting the second wavelength range to be first level; when the wrinkle degree is greater than the first wrinkle degree and less than a second wrinkle degree, control the irradiation intensity of the number of openings of the light-emitting units capable of emitting the second wavelength range to be second level; when the wrinkle degree is greater than the second wrinkle degree, control the irradiation intensity of the number of openings of the light-emitting units capable of emitting the second wavelength range to be third level; wherein the first wrinkle degree is less than the second wrinkle degree. The first level irradiation intensity is weaker than the second level, and the second level irradiation intensity is weaker than the third level.

[0130] When the number of turned-on light-emitting units capable of emitting the second wavelength range is all and the irradiation intensity of each light-emitting unit capable of emitting the second wavelength range is the same, the adjusted parameter is the irradiation time, when the wrinkle degree is less than the first wrinkle degree, the irradiation time of the number of turned-on light-emitting units capable of emitting the second wavelength range is controlled to be the first duration; when the wrinkle degree is greater than the first wrinkle degree and less than the second wrinkle degree, the irradiation time of the number of turned-on light-emitting units capable of emitting the second wavelength range is controlled to be the second duration; when the wrinkle degree is greater than the second wrinkle degree, the irradiation time of the number of turned-on light-emitting units capable of emitting the second wavelength range is controlled to be the third duration; wherein the first wrinkle degree is less than the second wrinkle degree. Wherein the first duration is less than the second duration, and the second duration is less than the third duration.

[0131] The first wrinkle degree, the second wrinkle degree, the first duration, the second duration, the third duration, the first number, the second number, the third number, the first irradiation intensity, the second irradiation intensity, and the third irradiation intensity in the above embodiments can be calibrated in advance by experiments and stored in the controller.

The more melanin, the more spots on the skin, and the lower the whitening degree. Alternatively, the whitening degree can be determined by a skin color sensor. The higher the color value, the darker the skin, and the lower the whitening degree.

[0139] The light therapy instrument can obtain the whitening degree of the skin according to the parameters collected by the collection sensor.

The four-level irradiation intensity is stronger than the five-level, and the five-level irradiation intensity is stronger than the six-level.

[0146] When the number of opened light-emitting units capable of emitting the first wavelength range is all, and the irradiation intensity of each light-emitting unit capable of emitting the first wavelength range is the same, the adjusted parameter is the irradiation time, when the whitening degree is less than the first whitening degree, the irradiation time of the number of opened light-emitting units capable of emitting the second wavelength range is controlled to be the fourth duration; when the whitening degree is greater than the first whitening degree and less than the second whitening degree, the irradiation time of the number of opened light-emitting units capable of emitting the second wavelength range is controlled to be the fifth duration; when the whitening degree is greater than the second whitening degree, the irradiation time of the number of opened light-emitting units capable of emitting the second wavelength range is controlled to be the sixth duration; wherein the first whitening degree is less than the second whitening degree.

[0176] In addition, the embodiments claimed in the present application, in which the light emitting unit can simultaneously emit light of the first wavelength range and the second wavelength range, can achieve the effects summarized above.

[0177] In summary, according to the light therapy instrument and the control method of the light therapy instrument provided in the embodiments of the present application, the light therapy instrument comprises: a main body structure and a plurality of light emitting units arranged on the main body structure; wherein the light emitting units can emit light comprising at least one of the following: light in a first wavelength range of 590nm-850nm and light in a second wavelength range of 1072±15nm; the light emitted by the light emitting units can act on the skin area of the user. Thus, the light therapy instrument can emit light in the 590nm-850nm wavelength range or the 1072±15nm wavelength range alone, or emit light in the 590nm-850nm wavelength range and the 1072±15nm wavelength range simultaneously. Since the light in the 1072±15nm wavelength range is longer, the energy of the light with the longer wavelength is larger, so it can penetrate melanin, blood vessels and water, and then enter the dermis layer, promote the regeneration of collagen in the dermis layer, and reduce the generation of wrinkles. Furthermore, the light in the 590nm-850nm wavelength range can be fully absorbed by the melanin at the boundary between the epidermis and the dermis layer during penetration of the epidermis, and the generation thereof is inhibited, thereby achieving the effect of whitening. Thus, when the light in the two wavelength ranges acts on the skin comprehensively, it can have a synergistic effect, can simultaneously whiten and remove wrinkles, improve the user experience, and increase the user satisfaction.
