Abstract
Description
Technical Field
[0001] This utility model relates to the field of phototherapy beauty device technology, and in particular to a phototherapy beauty device. Background Technology
[0002] LED phototherapy devices use light energy of specific wavelengths to act on skin cells (photobiological regulation), promoting cell activity, collagen synthesis, and skin repair, thereby improving various skin problems such as wrinkles, acne, and pigmentation. Existing large-area home phototherapy devices are usually flat panel types. Because home phototherapy devices have much lower power than professional phototherapy equipment, they often operate at a high irradiance continuously to achieve results. While this method allows for some skin improvement, it can also easily cause significant skin damage, leading to customer complaints. Utility Model Content
[0003] This invention provides a phototherapy beauty device that aims to minimize skin damage while ensuring the effectiveness of the phototherapy beauty device on the skin.
[0004] To achieve the above objectives, the phototherapy beauty device proposed in this utility model includes:
[0005] A light-emitting panel has a light-emitting surface, and the light-emitting panel is provided with a light source module for outputting beauty lights from the light-emitting surface;
[0006] A drive control module is electrically connected to the light source module and controls the working state of the light source module.
[0007] The main control module is communicatively connected to the drive control module and sends control signals to the drive control module. The drive control module is used to control the output power of the light source module to switch sequentially between multiple power values according to the control signals of the main control module, so that the irradiance output by the light-emitting panel switches sequentially between multiple irradiance values.
[0008] In some embodiments, the drive control module includes a current regulation unit and a drive unit, wherein the drive unit is electrically connected to the light source module, and the current regulation unit is electrically connected to the drive unit;
[0009] The current regulating unit is communicatively connected to the main control module. The current regulating unit controls the current of the driving unit to drive the light source module according to the control signal of the main control module, so that the output power of the light source module switches sequentially between multiple power values.
[0010] In some embodiments, the drive control module controls the output power of the light source module to switch sequentially between a first power and a second power according to the control signal of the main control module, wherein the first power is greater than the second power.
[0011] In some embodiments, the second power is greater than or equal to 30% of the first power and less than or equal to 50% of the first power.
[0012] In some embodiments, when the output power of the light source module is the first power, the irradiance output by the light-emitting panel is greater than or equal to 10 mW / cm². 2 And less than or equal to 20mw / cm 2 .
[0013] In some embodiments, the light source module includes a plurality of LED units arranged on the light-emitting panel, wherein the plurality of LED units emit light toward the light-emitting surface;
[0014] The drive control module controls the LED unit to output according to a preset pulse mode. The output parameters of the preset pulse mode are: the duration of the sub-pulse is less than or equal to 0.5 milliseconds, the time interval of the sub-pulse is less than or equal to 1 millisecond, the time interval of the pulse train is less than or equal to 100 milliseconds, and the number of pulses is less than or equal to 1000.
[0015] In some embodiments, the sub-pulse time is greater than or equal to 100 microseconds and less than or equal to 500 microseconds;
[0016] The time interval of the sub-pulse is greater than or equal to 100 microseconds and less than or equal to 300 microseconds;
[0017] The number of pulses is greater than or equal to 2 and less than or equal to 10;
[0018] The time interval of the pulse train is greater than or equal to 500 microseconds and less than or equal to 2000 microseconds.
[0019] In some embodiments, the sub-pulse duration is 500 microseconds, the sub-pulse time interval is 150 microseconds, the number of pulses is 4, and the pulse train time interval is 750 microseconds.
[0020] In some embodiments, the LED unit includes at least one of red LED, blue LED, yellow LED, green LED, infrared LED, and ultra-infrared LED.
[0021] In some embodiments, the light emission angle of the LED unit is greater than or equal to 60° and less than or equal to 120°.
[0022] In some embodiments, the main control module is located on the light-emitting panel; or, the main control module and the drive control module are wirelessly connected, and the main control module and the light-emitting panel are separately configured.
[0023] In some embodiments, the light-emitting panel can be bent toward one side of its light-emitting surface to divide it into at least two sub-panels, and the included angle between two adjacent sub-panels is less than 180°.
[0024] The present invention relates to a phototherapy beauty device. The drive control module, based on the control signal from the main control module, controls the output power of the light source module to sequentially switch between multiple power values, thereby causing the irradiance output by the light-emitting panel to sequentially switch between multiple irradiance values. Thus, during the phototherapy beauty treatment, the irradiance output by the light-emitting panel will cyclically change between at least two different irradiance levels. When the light-emitting panel outputs high irradiance, the skin can quickly reach an active state (i.e., awaken the skin), maintaining high light energy absorption efficiency and producing a better effect. When the light-emitting panel switches from high to relatively low irradiance, although the irradiance decreases, the skin temperature does not drop significantly in a short time due to continued irradiation, maintaining an active state and high light energy absorption. Then, the light-emitting panel switches back to high irradiance output, quickly returning the skin to its optimal active state. This cycle repeats, keeping the skin active throughout the entire treatment process. Therefore, the effect of this embodiment on the skin is essentially the same as that of continuous high irradiance irradiation (e.g., the effect on improving skin rejuvenation is essentially the same). Furthermore, the periods of relatively low irradiance output by the light-emitting panel have a soothing effect on the skin, significantly reducing the rate of water loss from the epidermis and preventing severe heat accumulation that can lead to dryness, burns, and inflammation caused by continuous high irradiance irradiation, thus minimizing skin damage.
[0025] In summary, compared with the existing technology that continuously controls the light-emitting panel to output a fixed high irradiance, the present invention can effectively reduce skin damage and improve the safety of using the phototherapy beauty device while ensuring the effect of the phototherapy beauty device on the skin.
[0026] In addition, compared with the control panel continuously outputting high irradiance, the technical solution of this utility model also reduces the power consumption during the entire irradiation process, making the overall efficiency of the phototherapy beauty device higher.

[0035] Currently, LED light therapy beauty devices are becoming increasingly popular among users. These devices use specific wavelengths of light energy to act on skin cells (photobiological regulation), promoting cell activity, collagen synthesis, and skin repair, thereby improving various skin problems such as wrinkles, acne, and pigmentation. Because home-use light therapy devices have much lower power than professional-grade devices, they typically operate at a high irradiance level continuously to achieve their intended effect. While this method does provide some improvement, it can also easily cause significant skin damage, leading to customer complaints.
[0036] In view of the above-mentioned shortcomings of existing phototherapy beauty devices, the applicant of this application has proposed a technical solution that can effectively solve the above-mentioned problems of existing phototherapy beauty devices through extensive research and experimentation.
[0037] This utility model proposes a phototherapy beauty device.
[0038] Reference Figure 1 and Figure 2 In this embodiment, the phototherapy beauty device includes a light-emitting panel 10, a drive control module 40, and a main control module 30.
[0039] The light-emitting panel 10 has a light-emitting surface 100, and the light-emitting panel 10 is provided with a light source module 20 for outputting beauty lights from the light-emitting surface 100.
[0040] The main control module 30 is communicatively connected to the drive control module 40, and the main control module 30 is used to send control signals to the drive control module 40. These control signals may include power information, time information, etc.; wherein the power information may include at least a first power and a second power, and the time information may include at least the duration corresponding to each power in the power information (such as the duration corresponding to the first power, the duration corresponding to the second power, etc.). Of course, the power information may also include more powers (including a third power, a fourth power, etc.).
[0041] The drive control module 40 is electrically connected to the light source module 20 and controls the operating state of the light source module 20; for example, controlling the turning on and off of the light source module 20, and controlling the operating parameters of the light source module 20 (e.g., output power), etc. In this embodiment, the drive control module 40 is used to control the output power of the light source module 20 to sequentially switch between multiple power values according to the control signal of the main control module 30, so that the irradiance output by the light-emitting panel 10 sequentially switches between multiple irradiance values.
[0042] Under the same conditions, the greater the output power of the light source module 20, the greater the energy of the emitted light from the light-emitting panel 10, that is, the higher the irradiance output by the light-emitting panel 10. Therefore, when the output power of the light source module 20 cycles between multiple power values in sequence, the irradiance output by the light-emitting panel 10 cycles between multiple corresponding irradiance values in sequence.
[0043] For example, when the output power of the light source module 20 is the first power, the irradiance output by the light-emitting panel 10 is the first irradiance. When the output power of the light source module 20 is the second power, the irradiance output by the light-emitting panel 10 is the second irradiance. The output power of the light source module 20 cycles between the first power and the second power in sequence, which causes the irradiance output by the light-emitting panel 10 to cycle between the first irradiance (i.e., the irradiance corresponding to the first power) and the second irradiance (i.e., the irradiance corresponding to the second power) in sequence. For example, when the output power of the light source module 20 is the first power, the irradiance output by the light-emitting panel 10 is the first irradiance; when the output power of the light source module 20 is the second power, the irradiance output by the light-emitting panel 10 is the second irradiance; and when the output power of the light source module 20 is the third power, the irradiance output by the light-emitting panel 10 is the third irradiance. The output power of the light source module 20 cycles through the first power, the second power, and the third power in sequence, causing the irradiance output by the light-emitting panel 10 to cycle through the first irradiance (i.e., the irradiance corresponding to the first power), the second irradiance (i.e., the irradiance corresponding to the second power), and the third irradiance (i.e., the irradiance corresponding to the third power) in sequence.
[0044] For example, the control signal sent from the main control module 30 to the drive control module 40 includes a first power, a second power, and the duration corresponding to the first power (denoted as the first time period) and the duration corresponding to the second power (denoted as the second time period); wherein the first power and the second power are not equal (for example, the first power is greater than the second power). Then, according to the control signal from the main control module 30, the drive control module 40 controls the output power of the light source module 20 to sequentially switch between multiple power values in a cyclical manner: controlling the light source module 20 to output at the first power for the first time period, that is, the irradiance output by the light-emitting panel 10 is the first irradiance, then switching to output at the second power for the second time period, that is, the irradiance output by the light-emitting panel 10 switches to the second irradiance, then switching back to output at the first power for the first time period, that is, the irradiance output by the light-emitting panel 10 switches back to the first irradiance, and so on in a cyclical manner; in this way, the irradiance output by the light-emitting panel 10 sequentially switches between the first irradiance and the second irradiance.
[0045] For example, the control signal sent from the main control module 30 to the drive control module 40 includes a first power, a second power, and the duration corresponding to the first power (denoted as the first time period) and the duration corresponding to the second power (denoted as the second time period); wherein the first power and the second power are not equal (for example, the first power is greater than the second power). Then, according to the control signal from the main control module 30, the drive control module 40 controls the output power of the light source module 20 to sequentially switch between multiple power values in a cyclical manner: controlling the light source module 20 to output at the first power for the first time period, that is, the irradiance output by the light-emitting panel 10 is the first irradiance, then switching to output at the second power for the second time period, that is, the irradiance output by the light-emitting panel 10 switches to the second irradiance, then switching back to output at the first power for the first time period, that is, the irradiance output by the light-emitting panel 10 switches back to the first irradiance, and so on in a cyclical manner; in this way, the irradiance output by the light-emitting panel 10 sequentially switches between the first irradiance and the second irradiance.
[0046] The technical solution of the phototherapy beauty device in this embodiment is that the drive control module 40 controls the output power of the light source module 20 to switch sequentially between multiple power values according to the control signal of the main control module 30, so that the irradiance output by the light-emitting panel 10 switches sequentially between multiple irradiance values. In this way, during the beauty care process of the phototherapy beauty device, the irradiance output by the light-emitting panel 10 will cycle between at least two different irradiance values. When the light-emitting panel 10 outputs high irradiance, the skin can quickly reach an active state (i.e., awaken the skin), maintaining a high light energy absorption efficiency and producing a better effect on the skin. When the light-emitting panel 10 switches from a high irradiance output to a relatively low irradiance output, although the irradiance decreases, the skin temperature will not drop significantly in a short time under the continued irradiation effect of the light-emitting panel 10, maintaining an active state and still maintaining a high light energy absorption effect. Then, the light-emitting panel 10 switches back to high irradiance output, allowing the skin to quickly return to its optimal active state. This cycle continues, keeping the skin active throughout the entire treatment process. Therefore, the effect of the technical solution in this embodiment on the skin is basically the same as the effect of continuous high irradiance irradiation (e.g., the effect on improving skin rejuvenation is basically the same). Furthermore, during the period when the light-emitting panel 10 outputs relatively low irradiance, it has a soothing effect on the skin, which can significantly reduce the rate of water loss from the skin epidermis and avoid the negative effects such as dryness, burns, and inflammation caused by severe heat accumulation on the skin due to continuous high irradiance, thereby reducing damage to the skin.
[0047] In summary, compared with the prior art which continuously controls the light-emitting panel 10 to output a fixed high irradiance, the technical solution of this embodiment can effectively reduce skin damage while ensuring the effect of the phototherapy beauty device on the skin, thus improving the safety of the phototherapy beauty device.
[0048] In addition, compared to the control panel continuously outputting high irradiance, the technical solution of this embodiment also reduces the power consumption during the entire irradiation process, making the overall efficiency of the phototherapy beauty device higher.
[0049] In some embodiments, the drive control module 40 controls the output power of the light source module 20 to switch sequentially between a first power and a second power. Initially, the output power of the light source module 20 is set to a higher power (e.g., the first power). After operating at the first power for a first time period, the output power is switched to a relatively lower power (e.g., the second power) for a second time period. Then, the output power is switched back to the first power for the same first time period, and this cycle repeats. Thus, when the phototherapy beauty device performs skin care, the light-emitting panel 10 initially outputs a higher first irradiance for a first time period, allowing the skin to quickly reach an active state, accelerating the absorption of light energy and producing a better effect. The light-emitting panel 10 then outputs a relatively lower second irradiance for a second time period, keeping the skin in an active state and maintaining optimal light energy absorption. In this way, during each treatment with the phototherapy beauty device, the skin is quickly brought to an active state, maximizing the effect of the light-emitting panel 10's irradiation.
[0050] In some embodiments, the control signal of the main control module 30 includes a first power, a second power, a first time period corresponding to the first power, and a second time period corresponding to the second power. The drive control module 40 controls the output power of the light source module 20 to cycle between the first power and the second power, so that the irradiance output by the light-emitting panel 10 cycles between the first irradiance and the second irradiance. The second power is greater than or equal to 30% of the first power and less than or equal to 50% of the first power, that is, the second irradiance is greater than or equal to 30% of the first irradiance and less than or equal to 50% of the first irradiance. The applicant's research has found that when the ratio of the second irradiance to the first irradiance is within the range of 30% to 50%, it can achieve an effect essentially consistent with continuous high irradiance output (such as continuous first irradiance output), and can significantly reduce the rate of epidermal water loss during skin care, greatly reducing damage to the skin. Furthermore, compared to continuous high-intensity output, the power consumption during the entire irradiation process can be reduced by 15% to 25%, thereby increasing the overall efficiency of the phototherapy beauty device by 15% to 25%.
[0051] In some embodiments, the second power may be 30%, 31%, 32%, 33%, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47%, 48%, 49%, or 50% of the first power.
[0052] In some embodiments, when the drive control module 40 controls the light source module 20 to output a first power, the irradiance (i.e., the first irradiance) output by the light-emitting panel 10 is less than or equal to 100 mW / cm². 2 For example, the first irradiance can be taken as 10 mw / cm. 2 15mw / cm 2 20mw / cm 2 25mw / cm 2 30mw / cm 2 40mw / cm 2 50mw / cm 2 60mw / cm 2 70mw / cm 2 80mw / cm 2 90mw / cm 2 Or 100mw / cm 2 For different types of users' skin and different skin areas, the irradiance output by the light-emitting panel 10 is within this range, which is relatively safe and can avoid most safety risks.
[0053] In some embodiments, when the drive control module 40 controls the light source module 20 to output a first power, the irradiance (i.e., the first irradiance) output by the light-emitting panel 10 is greater than or equal to 10 mW / cm². 2 And less than or equal to 20mw / cm 2 Research has shown that the irradiance output from the light-emitting panel 10 of the phototherapy beauty device is 10 mw / cm². 2 Up to 10mw / cm 2 Within this range, it can achieve good cosmetic improvement effects (such as rejuvenation) for most users' skin. Furthermore, with the control method of this application, skin damage can be basically eliminated, ensuring both effectiveness and safety of use.
[0054] In some embodiments, the first irradiance may be 10 mw / cm². 2 11mw / cm 2 12mw / cm 2 13mw / cm 2 14mw / cm 2 15mw / cm 2 16mw / cm 2 17mw / cm 2 18mw / cm 2 19mw / cm 2 Or 10mw / cm 2 .
[0055] In some embodiments, the first irradiance is 20 mw / cm². 2 The second irradiance is 6 mw / cm². 2 .
[0056] In some embodiments, the first irradiance is 20 mw / cm². 2 The second irradiance is 8 mw / cm². 2 .
[0057] In some embodiments, the first irradiance is 20 mw / cm². 2 The second irradiance is 10 mw / cm². 2 .
[0058] In some embodiments, the first irradiance is 15 mw / cm². 2 The second irradiance is 5 mw / cm². 2 .
[0059] In some embodiments, the first irradiance is 15 mw / cm². 2 The second irradiance is 7 mw / cm². 2 .
[0060] In some embodiments, the first irradiance is 10 mw / cm². 2 The second irradiance is 3 mw / cm². 2 .
[0061] In some embodiments, the first irradiance is 10 mw / cm². 2 The second irradiance is 4 mw / cm². 2 .
[0062] In some embodiments, the first irradiance is 10 mw / cm². 2 The second irradiance is 5 mw / cm². 2 .
[0063] In some embodiments, the first time period is greater than or equal to 10 seconds and less than or equal to 30 seconds; the second time period is greater than or equal to 10 seconds and less than or equal to 30 seconds. The applicant's research has found that when the first time period (the time period during which the light-emitting panel 10 outputs a first irradiance) and the second time period (the time period during which the light-emitting panel 10 outputs a second irradiance) are within the above-mentioned numerical range, they can generally maintain a good cosmetic effect (such as a rejuvenating effect) on the skin of most users, while effectively reducing skin damage. Furthermore, the first irradiance output by the light-emitting panel 10 of the phototherapy beauty device is 10 mw / cm². 2 Up to 10mw / cm 2 When combined, they can achieve better results.
[0064] In some embodiments, the first time period may be 10 seconds, 11 seconds, 12 seconds, 13 seconds, 14 seconds, 15 seconds, 16 seconds, 17 seconds, 18 seconds, 19 seconds, 20 seconds, 21 seconds, 22 seconds, 23 seconds, 24 seconds, 25 seconds, 26 seconds, 27 seconds, 28 seconds, 29 seconds, or 30 seconds.
[0065] In some embodiments, the second time period can be 10 seconds, 11 seconds, 12 seconds, 13 seconds, 14 seconds, 15 seconds, 16 seconds, 17 seconds, 18 seconds, 19 seconds, 20 seconds, 21 seconds, 22 seconds, 23 seconds, 24 seconds, 25 seconds, 26 seconds, 27 seconds, 28 seconds, 29 seconds, or 30 seconds.
[0066] In some embodiments, the first time period is 30 seconds and the second time period is 10 seconds.
[0067] In some embodiments, the first time period is 30 seconds and the second time period is 15 seconds.
[0068] In some embodiments, the first time period is 30 seconds and the second time period is 20 seconds.
[0069] In some embodiments, the first time period is 30 seconds and the second time period is 25 seconds.
[0070] In some embodiments, the first time period is 30 seconds and the second time period is 30 seconds.
[0071] In some embodiments, the first time period is 25 seconds and the second time period is 10 seconds.
[0072] In some embodiments, the first time period is 25 seconds and the second time period is 15 seconds.
[0073] In some embodiments, the first time period is 25 seconds and the second time period is 20 seconds.
[0074] In some embodiments, the first time period is 25 seconds and the second time period is 25 seconds.
[0075] In some embodiments, the first time period is 20 seconds and the second time period is 10 seconds.
[0076] In some embodiments, the first time period is 20 seconds and the second time period is 15 seconds.
[0077] In some embodiments, the first time period is 20 seconds and the second time period is 20 seconds.
[0078] Reference Figure 3 In some embodiments, the drive control module 40 includes a current regulation unit 42 and a drive unit 43. The current regulation unit 42 is electrically connected to the drive unit 43, and the drive unit 43 is electrically connected to the light source module 20. The main control module 30 can control the light source module 20 to turn on and off through the drive unit 43. The current regulation unit 42 is communicatively connected to the main control module 30 and controls the current of the drive unit 43 to drive the light source module 20 according to the control signal of the main control module 30, so that the output power of the light source module 20 cycles sequentially among multiple power values.
[0079] Specifically, the current adjustment unit 42 receives a control signal sent by the main control module 30. This control signal may include power information, time information, etc. The power information may include at least a first power and a second power, and the time information may include at least the duration corresponding to each power (e.g., the duration corresponding to the first power and the duration corresponding to the second power). In this embodiment, the light source module 20 uses constant voltage drive. The current adjustment unit 42 controls the current driving the drive unit 43 to operate the light source module 20 based on the power and time information in the received control signal, thereby adjusting the output power of the light source module 20 (i.e., drive voltage × operating current). For example, the current regulating unit 42 first controls the driving unit 43 to drive the light source module 20 to operate at a first current, so that the light source module 20 operates at a first power (driving voltage × first current) for a first time period. Then, it controls the driving unit 43 to drive the light source module 20 to operate at a second current, so that the light source module 20 operates at a second power (driving voltage × second current) for a second time period. Then, it controls the driving unit 43 to drive the light source module 20 to operate at a first current again, so that the light source module 20 operates at the first power (driving voltage × first current) for a first time period again. This cycle is repeated so that the output power of the light source module 20 is sequentially switched between multiple power values, so that the irradiance output by the light-emitting panel 10 is sequentially switched between a first irradiance and a second irradiance.
[0080] In this embodiment, the operating current of the light source module 20 is controlled and adjusted according to the control signal of the main control module 30, so that the output power of the light source module 20 can be switched sequentially among multiple power values. The overall hardware structure is simple and the cost is low.
[0081] Of course, in other embodiments, the drive control module 40 may also use other hardware structures or methods to realize the output power of the light source module 20 to switch sequentially among multiple power values.
[0082] In some embodiments, the light source module 20 includes a plurality of LED units arranged on the light-emitting panel 10, all of which emit light toward the light-emitting surface 100. The plurality of LED units on the light-emitting panel 10 may be arranged in an array, randomly distributed, or distributed along a specific path, etc. In some embodiments, the emission angle of the LED unit may be greater than or equal to 60° and less than or equal to 120°. For example, the emission angle of the LED unit may be 60°, 70°, 80°, 90°, 100°, 110°, or 120°.
[0083] In this embodiment, the drive control module 40 controls the LED unit to output according to a preset pulse pattern. The output parameters of the preset pulse pattern are: sub-pulse duration less than or equal to 0.5 milliseconds, sub-pulse time interval less than or equal to 1 millisecond, pulse train time interval less than or equal to 100 milliseconds, and pulse number less than or equal to 1000. That is, the drive control module 40 controls the LED unit to output in a microsecond-level pulse output pattern.
[0084] The applicant of this application has discovered through extensive research and experimentation that the LED unit adopts a micro-level pulse output mode, which has a much better skin-promoting effect compared to continuous light irradiation and millisecond-level pulse output mode. Therefore, the technical solution of this embodiment can further enhance the skin-beautifying effect of the phototherapy beauty device (such as skin rejuvenation effect, anti-aging and anti-wrinkle effect).
[0085] In some embodiments, the sub-pulse duration is greater than or equal to 100 and less than or equal to 500 microseconds; the sub-pulse time interval is greater than or equal to 100 microseconds and less than or equal to 300 microseconds; the number of pulses is greater than or equal to 2 and less than or equal to 10; and the pulse train time interval is greater than or equal to 500 microseconds and less than or equal to 2000 microseconds. Through extensive research and experimental data analysis, it has been determined that outputting within the above parameter range results in a more stable and prominent skin-promoting effect, thereby better enhancing the skin-beautifying effect of the phototherapy beauty device.
[0086] Specifically, some of the experimental data from the large amount of research data are shown in the table below:
[0087]
[0088] In some embodiments, the sub-pulse duration is 500 microseconds, the sub-pulse interval is 150 microseconds, the number of pulses is 4, and the pulse train interval is 750 microseconds. As can be seen from the experimental data in the table above, when the control panel uses the output parameters of this embodiment (i.e., sub-pulse duration of 500 microseconds, sub-pulse interval of 150 microseconds, pulse train interval of 750 microseconds, and number of pulses of 4) to control the LED unit to output in a pulse mode, the skin reaches the highest pre-collagen level (the average collagen level reaches 579%). Therefore, controlling the LED unit to output in a pulse mode using these output parameters to irradiate the skin is a pulse output method that conforms to cell rhythms, maximally stimulating fibroblast collagen production, achieving the best collagen-promoting effect on the skin, and significantly enhancing the skin rejuvenation, anti-aging, and anti-wrinkle effects of the phototherapy beauty device.
[0089] In some embodiments, the LED unit includes at least one of red LED, blue LED, yellow LED, green LED, infrared LED, and ultra-infrared LED.
[0090] In some embodiments, the LED unit includes only red LEDs, blue LEDs, yellow LEDs, green LEDs, infrared LEDs, or ultra-infrared LEDs;
[0091] In some embodiments, the LED unit includes any two of the following: red LED, blue LED, yellow LED, green LED, infrared LED, and ultra-infrared LED.
[0092] In some embodiments, the LED unit includes any three of the following: red LED, blue LED, yellow LED, green LED, infrared LED, and ultra-infrared LED.
[0093] In some embodiments, the LED unit includes any four of the following: red LED, blue LED, yellow LED, green LED, infrared LED, and ultra-infrared LED.
[0094] In some embodiments, the LED unit includes any five of the following: red LED, blue LED, yellow LED, green LED, infrared LED, and ultra-infrared LED.
[0095] In some embodiments, the LED unit includes red LEDs, blue LEDs, yellow LEDs, green LEDs, infrared LEDs, and ultra-infrared LEDs.
[0096] Specifically, phototherapy beauty devices can be configured with LEDs of corresponding colors or combinations of corresponding colors in the LED units according to the desired skin effects. The number of various LEDs included in each LED unit can also be configured according to requirements.
[0097] In some embodiments, the main control module 30 may be disposed in the light-emitting panel 10, for example, inside the housing of the light-emitting panel 10. The main control module 30 and the drive control module 40 may be connected via signal lines or wirelessly.
[0098] In some embodiments, the main control module 30 may be separately set from the light-emitting panel 10, that is, the main control module 30 and the light-emitting panel 10 are two separate parts, and the main control module 30 is wirelessly connected to the drive control module 40 (e.g., Bluetooth, Wi-Fi, 4G, etc.).
[0099] Combined with reference Figure 1 and Figure 4In some embodiments, the light-emitting panel 10 can be bent toward the side of its light-emitting surface 100 to divide it into at least two sub-panels 11 (two are shown as an example in the figure), and the included angle between two adjacent sub-panels 11 is less than 180°.
[0100] The light-emitting panel 10 can be composed of multiple sub-panels 11 spliced together. For example, two adjacent sub-panels 11 can be connected by a hinge.
[0101] The light-emitting panel 10 can also be a single panel structure with a bendable deformation area (e.g., a flexible structure) on the panel structure. Users can bend the panel structure along the deformation area according to their needs, so that the light-emitting panel 10 is divided into multiple sub-panels 11.
[0102] The phototherapy beauty device of this embodiment adopts a design where the light-emitting panel 10 can be bent into multiple sub-panels 11, allowing the user to bend the light-emitting panel 10 to a corresponding state (e.g., according to the curvature of the skin surface to be irradiated) based on the desired curvature. Figure 4 (as shown in the image) to better irradiate and care for the skin.
[0103] Furthermore, when the light-emitting panel 10 is bent into multiple sub-panels 11 to irradiate the skin, the edge area of the skin (the two sides of the middle part of the skin) can be covered by the light path of the edge of the light-emitting angle of the multiple sub-panels 11. Thus, the edge area of the skin is irradiated by the overlapping light paths of the multiple sub-panels 11. Therefore, the irradiation energy received by the edge area of the skin is enhanced, and the energy difference with that of the skin irradiated by the center area of the light-emitting angle of the sub-panel 11 is smaller. This can achieve a balance of irradiation energy in various areas of the skin and improve the uneven irradiation of various skin areas on complex skin surfaces.

All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
