Description

TECHNICAL FIELD

[0001] The present application relates to the field of optical pulse technology, and in particular to an output method of an optical pulse device. BACKGROUND

[0002] Irradiation of skin with pulses of light of a specific wavelength can have positive medical purposes, such as skin rejuvenation and hair removal. In the prior art, the output of the pulses of light is precisely controlled so that the energy can penetrate the epidermis and reach the target tissue, and the purposes are achieved by acting on the target tissue with this part of the energy.

[0003] In order to release energy, the prior art discloses the continuous release of multiple pulses in a pulse train, so as to achieve the accumulation of energy and achieve better purposes. For example, in the case of skin areas with strong and thick hair, the designed pulse train release can have higher energy, but this configuration scheme is obtained based on the continuous release of pulses, and the controllability of the temperature rise of the epidermis is often ignored, causing unpredictable negative effects (such as a stinging and / or burning sensation) on the skin of the user. SUMMARY

[0004] The purpose of the present application is to provide a faster and more effective method and interactive interface for managing a controllable optical pulse device. Such a method and interface reduce the cognitive burden on the user and produce a more effective human-machine interface.

[0005] To achieve this purpose, the present application uses the following technical solutions:

[0006] According to some embodiments, an output method of an optical pulse device is described, the method comprising:

[0007] obtaining a light output instruction and a skin contact signal;

[0008] performing the output of light according to the output instruction and the skin contact signal;

[0009] wherein the output instruction comprises:

[0011] in the N-1th sub-pulse train, the Mth sub-pulse has a first pulse energy value J1;

[0012] in the Nth sub-pulse train, the Mth sub-pulse has a second pulse energy value J2;

[0013] wherein J1

[0014] In some embodiments, the sub-pulses in each of the sub-pulse trains have an increasing pulse energy value in sequence.

[0015] In some embodiments, two adjacent sub-pulses have a pulse interval, at least part of which is used for charging.

[0016] In some embodiments, at least another part of the pulse interval is not used for charging.

[0017] In some embodiments, in each of the sub-pulse trains, the first sub-pulse and the second sub-pulse have a pulse interval of T≥500 ms, and the length of time t1 used for charging in the pulse interval is ≤300 ms.

[0018] In some embodiments, in one of the light pulse trains, the light is continuously output with two sub-pulse trains, each of which has three sub-pulses.

[0019] In some embodiments, the sub-pulse interval T1 of two adjacent sub-pulses in each of the sub-pulse trains satisfies: 500 ms≤T1≤600 ms.

[0020] In some embodiments, the sub-pulse train interval T2 of two adjacent sub-pulse trains satisfies: T2≥1 s.

[0021] In some embodiments, each of the sub-pulse trains has an increasing total pulse energy value in sequence.

[0022] In some embodiments, the pulse energy value of the Mth sub-pulse in each of the sub-pulse trains is significantly greater than the pulse energy values of the other sub-pulses.

[0023] Therefore, the present application provides a pulse light output method to provide better light energy release for user's skin, while ensuring the light effect and effectively improving the user's experience. BRIEF DESCRIPTION OF DRAWINGS

[0048] The present application will be further described below in conjunction with the accompanying drawings and embodiments. It can be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application. In addition, it should be noted that, for the purpose of description, only the parts related to the present application are shown in the drawings, but not all the structures.

[0049] In the description of the present application, unless otherwise explicitly specified and limited, the terms "connected", "connected", "fixed" should be understood in a broad sense, for example, it can be fixedly connected, or detachably connected, or integrated; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium; it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0050] In the present disclosure, unless specifically defined otherwise, the term "on" or "under" of a first feature with respect to a second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the term "on", "above" and "over" of a first feature with respect to a second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the first feature is horizontally higher than the second feature. The term "under", "below" and "underneath" of a first feature with respect to a second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the first feature is horizontally lower than the second feature.

[0051] In the description of the present embodiments, the terms "upper", "lower", "left", "right", and other orientation or positional relationships are based on the orientation or positional relationships shown in the drawings, and are only for the convenience of description and simplification of operation, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0052] The light pulse device configured to act on the user's skin can acquire input in contact with the user's skin through a sensor. For example, the light pulse device is arranged with one or more sensors adjacent to the light emitting surface, the light emitting surface contacts the user's skin, and the one or more sensors can collect the user's input and cause the light pulse device to provide output of pulsed light. As an example, the light pulse device can include a capacitive touch sensor that converts a physical or mechanical quantity when touching the skin into a capacitive change quantity and delivers information to the light pulse device to associate the output of pulsed light.

[0053] The user can control the output of pulsed light of the light pulse device through the interactive interface of the electronic device. The user can use the electronic device to operate the display. During operation, the user selects the interactive interface of the display regarding the list of information of interaction and / or the associated affordance (e.g., the user's finger interacts with the touch surface of the display, which includes finger movement and other interactions associated with the content displayed to the user). The user input can be used to control the touch output on the display. The electronic device can be used to provide corresponding haptic feedback to the user's finger. For example, the haptic feedback can be used to provide the user with a desired sensory change (e.g., vibration) when the user touches the affordance of the interactive interface. The haptic feedback can also be used to produce other haptic effects or visual change effects (e.g., changes in brightness, transparency, saturation, contrast, or other visual features).

[0054] Figure 1 is a schematic diagram of an exemplary system that can include a cosmetic type. As Figure 1As shown, the system includes a plurality of devices, such as a light pulsing device and other electronic devices in communication with the light pulsing device.

The control circuitry 510 and control circuitry 610 can include storage and processing circuitry (e.g., flash memory or other programmable read-only memory configured to form a solid-state drive, volatile memory such as static or dynamic random access memory, etc.) to support the operation of the system 700. The processing circuitry in the control circuitry 510 and control circuitry 610 can be used to collect input from sensors and other input devices, and can be used to control output devices. The processing circuitry can be based on one or more microprocessors, microcontrollers, digital signal processors, baseband processors and other wireless communication circuitry, power management units, audio chips, application specific integrated circuits, etc.

[0057] To support communication between the light pulsing device 500 and the electronic device 600 and / or to support communication between the equipment in the system 700 and external electronic equipment, the control circuit 510 can use a communication circuit 520 and / or the control circuit 610 can use a communication circuit 620. The control circuit 510 and / or the control circuit 610 can include antennas, radio frequency transceiver circuits, and other wireless communication circuits and / or wired communication circuits. For example, the control circuit 510 and / or the control circuit 610 (which can sometimes be referred to as control circuits and / or control and communication circuits) can support bidirectional wireless communication between the light pulsing device 500 and the electronic device 600 via a wireless link 701 (e.g., a wireless local area network link, a near field communication link, or other suitable wired or wireless communication link (e.g., a Bluetooth link, a WiFi link, a 60 GHz link, or other millimeter wave link, etc.)). The light pulsing device 500 and the electronic device 600 can also include power supply circuits for transmission and / or wireless power, and can include batteries. In configurations in which wireless power transmission is supported between the light pulsing device 500 and the electronic device 600, in-band wireless communication can be supported using inductive power transmission coils (exemplary).

[0058] The light pulsing device 500 and the electronic device 600 can include input- output devices, such as input-output device 530 and input-output device 630. The input- output device 530 and / or the input-output device 630 can be used to gather input from a user, to gather information about the environment surrounding the user, and / or to provide output to the user (e.g., the light pulsing device 500 gathers input through a capacitive sensor that it is in contact with the user's skin, the electronic device 600 gathers input through a touch sensitive display that a user's finger is in contact with). The light pulsing device 500 can include a sensor 531, and the electronic device 600 can include a sensor 631. The sensor 531 can include force sensors (e.g., strain gauges, capacitive force sensors, resistive force sensors), touch sensors, and / or proximity sensors (such as capacitive sensors), optical sensors (such as optical sensors that emit and detect light), contact sensors, ultrasonic sensors (e.g., ultrasonic sensors used to track device heading and position and / or to detect user input such as skin input), and / or other touch sensors and / or proximity sensors, monochrome and color ambient light sensors, image sensors, sensors for detecting position, orientation, and / or motion (e.g., accelerometers, magnetic sensors (such as compass sensors, gyroscopes, and / or inertial measurement units containing some or all of these sensors), optical sensors (such as self-mixing sensors that gather time-of-flight measurements and light detection and ranging (lidar) sensors), optical sensors (such as visual odometry sensors that use images gathered by a digital image sensor in a camera to gather position and / or direction information), gaze tracking sensors, visible light and / or infrared cameras with digital image sensors, temperature and humidity sensors, moisture sensors, and / or other sensors. In some arrangements, the light pulsing device 500 and / or the electronic device 600 can use the sensor 531 and / or the sensor 631 and or other input-output device 530 and / or input-output device 630 to gather input from a user (e.g., a capacitive sensor can be used to gather contact input from skin, a touch sensor that overlaps a display can be used to gather input from a touch screen).

[0059] If desired, the input-output device 530 and / or the input-output device 630 can include other devices 533 or other devices 633, such as displays (e.g., a display that shows the status of the light output in the light pulsing device 500), status indicator lights (e.g., light emitting diodes in the light pulsing device 500 and / or the electronic device 600 that act as power indicators, and other light-based output devices), speakers, and other audio output devices. The light pulsing device 500 and / or the electronic device 600 can also include power transmission and / or reception circuitry configured to transmit and / or receive wired and / or wireless power signals.

[0062] The various applications that execute on the electronic device optionally make use of at least one common physical user-interface device, such as a touch-sensitive surface. One or more functions of the touch-sensitive surface, as well as corresponding information displayed on the device, are optionally adjusted and / or varied

[0063] The touch-sensitive display of an electronic device sometimes referred to as a "touch screen," and sometimes referred to as a "touch-sensitive display system." The electronic device includes memory, storage, one or more processing units (CPU), peripheral device interfaces, radio frequency (RF) circuitry, audio circuitry, a speaker, a microphone, input / output (I / O) subsystem, other input control devices, and an external port. The electronic device optionally includes one or more contact intensity sensors (e.g., a contact intensity sensor for detecting intensity of contacts on a touch-sensitive surface).

[0064] It should be understood that the electronic device optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. Figure 2 The electronic device shows exemplary interactions of a user interface with control interfaces, the interaction interfaces shown in the illustrations are implemented in hardware, software, or a combination of both hardware and software, the presentation of different interfaces is achieved through contact interaction with the user.

[0065] The memory optionally includes high-speed random access memory and can also include nonvolatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other nonvolatile solid-state storage devices.

The RF circuitry can include a mixer, a filter, and an amplifier, for example. The RF circuitry can also include or be used with an antenna system, for example. The RF circuitry can convert a received electromagnetic signal to an electrical signal and can also convert an electrical signal to an electromagnetic signal for transmission.

[0068] The audio circuitry, speakers, and microphones provide an audio interface between the user and the electronic device. The audio circuitry receives audio data from the peripheral interface, converts the audio data to electrical signals, and transmits the electrical signals to the speakers. The speakers convert the electrical signals to human-audible sound waves. The audio circuitry also receives electrical signals converted by the microphones from sound waves. The audio circuitry converts the electrical signals to audio data and transmits the audio data to the peripheral interface for processing.

[0069] The input / output (I / O) system couples input / output peripherals on the electronic device, such as the touch screen and other input control devices, to the peripheral interface. The input / output (I / O) system optionally includes a display controller, an optical sensor controller, a haptic feedback controller, and one or more input controllers for other input or control devices.

The visual output optionally includes graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output optionally corresponds to user-interface objects.

[0071] The touch screen has a touch-sensitive surface, sensor, and sensor array that accepts input from the user based on haptic and / or tactile contact. The touch screen and the display controller detect contact, and convert the detected contact into data representing a user-interface interaction. In an example embodiment, the contact point between the touch screen and the user corresponds to a finger of the user.

[0072] In some embodiments, in addition to the touch screen, the electronic device optionally includes a touchpad for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad optionally is a touch surface that is separate from the touch screen or is an extension of the touch surface formed by the touch screen.

[0073] The electronic device also includes a power system for the supply of power to the various components. The power system optionally includes a power management system, one or more power sources, such as a power capacitor, alternating current adaptor, recharging system, power source status indicator, and any other components associated with the generation, management, and distribution of power for the electronic device.

[0074] In some embodiments, the software components stored in memory include at least one native application with an intuitive user interface, one or more interfaces or drivers for hardware components or the electronic device, and / or other software components, such as operating system software, communication software, contact / motion modules, graphics modules, text input modules, Global Positioning System (GPS) software, and applications that use cores of the processor 1004.

[0075] The operating system (e.g., iOS, HERMOSILLO, OS X, Windows, or an embedded operating system such as VxWorks) includes various software components and / or drivers for controlling and managing general system tasks (e.g., memory management, power management, storage control, and security

[0076] The communication module facilitates communication with other devices over one or more external ports 1006 and also includes various software components for handling data received by the RF circuitry and / or the external port 1006. The external port 1006 (e.g., Universal Serial Bus (USB), FIREWIRE, etc.) is adapted for coupling to other devices, such as wireless charging devices (e.g., Bluetooth® wireless charging devices), other communication devices, computing devices, storage devices, or various other peripheral devices.

[0077] The graphics module includes various known software components for rendering and displaying graphics on the touch screen or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual property) of graphics that are displayed. As used herein, the term "graphics" includes any object that can be displayed to a user, including without limitation text, web pages, icons (such as user-interface objects), digital images, videos, animations, and the like.

[0078] In some embodiments, the graphics module stores data representing graphics to be used. Each graphic is assigned a corresponding code. The graphics module receives, from applications etc., one or more codes specifying graphics to be displayed, and processes these codes, together with the received coordinate data and other graphics data, to generate screen image data for the display.

[0079] Examples of other application programs that are optionally stored in memory include other word processing applications, other image editing applications, drawing applications, presentation applications, JAVA-enabled applications, encryption, digital rights management, voice recognition, and voice replication.

[0080] As used herein, the term "affordance" refers to a user-interactive graphical user interface object that is optionally displayed on a display of electronic device 100, 200, and / or 500. For example, an image (e.g., an icon), a button, and text (e.g., a description of a body part) each optionally comprise an affordance.

[0081] As Figure 3A An example system for an electronic device is shown. In operation, the electronic device receives a user input (e.g., a tap input "Private Area"). In some embodiments, the user input includes a user's finger touch. Based on the finger touch, the network server identifies one or more tasks and parameters. For example, the network server interprets the text representation of the user's input to derive an intent and operationalize the intent into one or more tasks. In the illustrated embodiment, based on the user tapping "Private Area", the network server identifies a task to find a list of medical protocols related to "Private Area".

[0082] Additionally, the network server transmits a request to an identification storage for the "Private Area" input by the user. The request includes one or more parameters for identifying the "Private Area". In some embodiments, the one or more parameters can specify a naming pattern (e.g., "Six Pulse"), a light pulse intensity (e.g., "Strong"), and / or a property that acts on a hair density (e.g., "Hair Dense").

[0083] The identification storage can store data and / or models of a plurality of properties associated with the input area affordance (e.g., "Private Area") and related information. The properties that can be stored for the electronic device include, but are not limited to, a unique identifier, a light pulse output parameter, a body part identifier, a pulse train interval duration, etc. For example, the identification storage can store an identifier information associated with the input area affordance "Private Area", the area affordance "Perioral Area", the associated identifier information can include a property that the private area has a hair dense, the perioral area has a hair sparse.

[0084] The identification storage can be implemented via hardware, software, or a combination of both. In some embodiments, the identification storage device can be located on one or more of the light pulse device and the electronic device.

[0085] In some embodiments, the identification storage device identifies the location affordance (e.g., "private area") in the list of schemes based on parameters provided in a request from the network server. In some embodiments, the identification storage device determines whether the light pulsing device having an entry in the database has attributes matching the parameters. In some embodiments, the electronic device receives a request from the user to identify the location affordance (e.g., "private area") and provides data matching the same to the identification storage device through the network server. The electronic device responds to receiving the parameters from the network server and provides a joint command (e.g., containing control commands entered in other control pages) to the light pulsing device. In Figure 3A In the embodiment shown in FIG. 1, the joint command includes the text string "07 01 11C1 7F". In response to receiving the joint command, the light pulsing device outputs pulsed light associated with the parameters of the location affordance (e.g., outputs a six-pulse pulse train). In some embodiments, for different body locations but with the same attributes (e.g., different body locations of the user all have the feature of having thick hair), the electronic device can receive a request from the user to identify the location affordance (e.g., "underarm area") and provide parameters matching the same to the identification storage device through the network server, the identification matching other identifications with the same attributes can be used to instruct the light pulsing device to output light with at least partially the same parameters (e.g., the underarm area and the private area can both output light with six pulses, or the lip area and the body area can both output light with two pulses).

[0086] As Figure 3B Another exemplary system for an electronic device is shown. In operation, the electronic device receives a user's finger 01 input (e.g., tapping "private area"). In some embodiments, the light pulsing electronic device can include an identification storage device. At the identification storage device, based on a command output (e.g., text string "07 01 11C1 7F") from the electronic device providing the location affordance (e.g., private area) associated, the identification storage device determines whether the light pulsing device having an entry in the database has attributes matching the parameters, the light pulsing device responds to receiving the parameters from the identification storage device and outputs pulsed light associated with the parameters (e.g., outputs two-pulse light, four-pulse light, six-pulse light, eight-pulse light, or ten-pulse light).

[0087] Figure 2Exemplary interactions of an electronic device with a user interface and control interface are illustrated. In some embodiments, the home page of display 101 provides a list of options (e.g., a "scheme list" option 130a and a "my plans" option 130b). The user selects a scheme list option by touch to enter a first user interface 110. In the first user interface 110, the electronic device 100 displays options corresponding to different body parts, such as a perilip area option 140a, a body part option 140b, an armpit area option 140c, and a private area option 140d, and provides text representations 141a-d indicating these body parts. Because the perilip and body areas have sparse hair, while the armpits and pubic areas have dense and coarse hair, the corresponding energy representations for these areas are associated with corresponding attribute information. This indicates that these areas can be associated with pulsed light output functions with different parameters in subsequent secondary interfaces (e.g., the energy representations for the perilip and body areas are associated with dual-pulse pulsed light output functions, while the energy representations for the armpits and pubic areas are associated with six-pulse pulsed light output functions). Therefore, the pulsed light output functions for different areas can be marked and configured by selecting different area energy representations. This provides users with a more efficient interactive experience when performing the expected functions with electronic devices and / or light pulse devices.

[0088] In some embodiments, when a user clicks on the private area indicator 140d, the electronic device 100 detects a first interface input 102 corresponding to the selection of the private area indicator 140d in the first user interface 110. Figure 2In some embodiments, the display 101 displays the first control interface 120a. In the first control interface 120a, the affordances corresponding to the execution of functions of the light pulse device are displayed, including the first control affordance 121, which corresponds to the option of opening / closing the SHR (Super Hair Removal) function of the associated electronic device. The first control affordance 121 includes the function switch representation 1211 of the first control, which, when lit, indicates that the current is in the SHR mode (continuous output of multiple pulses, such as double pulses, four pulses, or six pulses, etc. in a light period) open state, and when the function switch representation 1211 is extinguished, it indicates that the current is in the SHR mode closed state (only one pulse of light output is provided in a light period, and the energy value is lower than the sum of the multiple pulse energy in the SHR mode). In some embodiments, the user inputs the private part representation 140d through the first user interface 110, which is associated with the second identification information corresponding to the private part, and the electronic device 100 detects whether the function switch representation 1211 of the first control in the first control affordance 121 is open. In response to detecting the opening of the function switch representation 1211, the electronic device 100 transmits a second function command associated with the second identification information to the light pulse device (for example, the light pulse device executes a six-pulse continuous flashing scheme in a light period, that is, the SHR mode of six pulses). In other embodiments, the user inputs the perioral part representation 140a through the first user interface 110, which is associated with the first identification information corresponding to the perioral part, and the electronic device 100 detects whether the function switch representation 1211 of the first control in the first control affordance 121 is open. In response to detecting the opening of the function switch representation 1211, the electronic device 100 transmits a first function command associated with the first identification information to the light pulse device (for example, the light pulse device executes a double-pulse continuous flashing scheme in a light period, that is, the SHR mode of double pulses). Displaying the same control affordances and settings in the same control interface provides a more efficient control interface for controlling different light outputs for different body parts. Allowing the user to access the control interface with the same control affordances from the same user interface reduces the user's cognitive burden. Moreover, the user does not need to open the associated control interface for each individual part in the application for independent configuration. In addition, the opening and closing of the control affordances correspond to the execution of two different functions, so the user can more efficiently operate and control in the control interface without having to operate the same type of control affordances (for example, the opening or closing of single flashing and double flashing) independently.

[0089] Figure 4A - Figure 4D An example interaction of the first control interface when the private part affordance 140d is selected is shown.

[0090] The first control interface 120a is displayed in a state with three control affordances.

[0091] In Figure 4A In the first control interface 120a displayed at the display 101, the first control affordance 121 corresponding to the SHR function, the second control affordance 122 corresponding to the flash periodicity function, and the third control affordance (123a, 123b) corresponding to the energy adjustment function are displayed; at the same time, the graphical affordance 142d related to the associated private part and the graphical affordance 125 related to the dynamic change of the light pulse device output are also displayed in the first control interface 120a (for example, in the light-emitting state, the graphical affordance 125 has a representation of a light-emitting dynamic figure; in the non-light-emitting state, the graphical affordance 125 has a representation of a static figure). In response to the first control input 103 (the function switch representation 1211 of the first control is in the on state) to the first control affordance 121, the electronic device 100 transmits a command of the first function associated with the first identification information to the light pulse device to execute a six-pulse flash scheme in one light period.

[0092] In Figure 4BIn the embodiment, the first control interface 120a displays the first control affordance 121 corresponding to the SHR (Super Hair Removal) function, the second control affordance 122 corresponding to the flash periodicity function, and the third control affordance (123a, 123b) corresponding to the energy adjustment function in the light pulse device; the second control affordance 122 includes the second control function switch 1221, which is associated with the display of the text "continuous flash" when activated, and the display of the text "single flash" when deactivated. In some embodiments, in response to the first control input of the first control affordance 121 (the first control function switch 1211 is in the on state) and the second control input 104 of the second control affordance 122 (the function switch 1221 is in the activated state), the electronic device 100 transmits the command of the first function associated with the first identification information and the command of the third function to the light pulse device, wherein the command of the third function is used to instruct the light pulse device to continuously perform light output in multiple light periods. In some embodiments, the light pulse device includes a contact sensor, and the light pulse device triggers continuous light output of one or more light periods in response to each contact of the contact sensor to the user's skin. In some embodiments, the user contacts the skin with the light output port of the light pulse device each time, and the light pulse device can confirm the trigger signal through the contact sensor, thereby realizing the automatic continuous pulse light output of multiple light periods when the light pulse device continuously contacts the user's skin multiple times, and each contact performs one light period of output (for example, one light period performs six-pulse pulse light output, or one light period performs double-pulse pulse light output).

[0093] In Figure 4CIn the first control interface 120a, the first control power indicator 121 corresponding to the SHR function, the second control power indicator 122 corresponding to the flash periodicity function, and the third control power indicator (123a, 123b) corresponding to the energy adjustment function in the light pulse device are displayed. The third control power indicator includes a third control power indicator 123a with energy reduction and a third control power indicator 123b with energy increase. The two control power indicators can adjust the output parameters of the pulse light (e.g., pulse power and / or pulse width) respectively in response to the user's input. In response to the user's input to the third control power indicator, the display 101 displays a text indication 124 of the energy level in the first control interface 120a. In some embodiments, in response to a first control input to the first control power indicator 121 (the first control's function switch indicator 1211 is in the off state), a second control input to the second control power indicator 122 (the second control's function switch indicator 1221 is in the inactive single flash state), and a third control input 105 to the third control power indicator (a text indication 124 indicating an energy level of 3), the electronic device 100 outputs to the light pulse device a command for a second function associated with second identification information, a command for a third function (single flash), and a command for a fourth function (energy level 3).

[0094] exist Figure 4D In the first control interface 120a, the first control power indicator 121 corresponding to the SHR function, the second control power indicator 122 corresponding to the flash periodicity function, and the third control power indicator (123a, 123b) corresponding to the energy adjustment function in the light pulse device are displayed. The third control power indicator includes the third control power indicator 123a for energy reduction and the third control power indicator 123b for energy increase. In response to the first control input of the first control power indicator 121 (the function switch 1211 of the first control is in the on state), the second control input 104 of the second control power indicator 122 (the function switch 1222 of the first control is in the inactive single flash state), and the third control input 105 of the third control power indicator (text indication 124 of energy level 1), the electronic device 100 outputs the second function command (six-pulse pulse light output), the third function command (single flash), and the fourth function command (energy level 1) associated with the second identification information to the light pulse device.

[0095] Electronic devices have an additional list interface between the user interface and the control interface to provide users with more detailed plans.

[0096] Figure 4EThe list interface is shown during the electronic device’s interaction with the user interface and the control interface. In some embodiments, the user first jumps to the list interface 120b by touching the affordance of the regimen list, and the list interface 120b displays the scheduled list indications corresponding to the body part affordances. In some embodiments, the user enters the list interface 120b after inputting the private body part affordance 140d, and the list interface 120b displays a plurality of and / or a plurality of groups of affordances with time period scheduling associated with the private body part affordance 140d, including one or more completed affordances 150a, one or more to-be-completed affordances 150b, and one or more uncompleted affordances 150c. In some embodiments, the electronic device 100 and / or the light pulse device store the execution information of the current pulse light output after each execution of the completed pulse light output, including the data and / or model of one or more attributes associated with the body part (e.g., the private body part) and related information, and when the user next touches and selects the body part affordance (e.g., the private body part affordance 140d) associated with the execution information, the list interface 120b displays the updated interface of the scheduled list indications corresponding to the associated private body part affordance 140d, including one or more completed affordances 150a, one or more to-be-completed affordances 150b, and one or more uncompleted affordances 150c. In some embodiments, the completed affordance 150a is associated with the display of the graphical affordance 151a (e.g., the execution of the regimen is completed, the graphical affordance 151a has the identification of the “√” figure), the text representation 152a (e.g., the text is “Private Treatment 1”), and is accompanied by the display of the execution status text representation 153a (e.g., the text is “Completed”); the to-be-completed affordance 150b is associated with the display of the graphical affordance 151b (e.g., the figure with the “lock” open), the text representation 152b (e.g., the text is “Private Treatment 2”), and is accompanied by the display of the execution status text representation 153b (e.g., the text is “To Complete”); the uncompleted affordance 150c is associated with the display of the graphical affordance 151c (e.g., the figure with the “lock” closed), the text representation 152c (e.g., the text is “Private Treatment 3”), and is accompanied by the display of the execution status text representation 153c (e.g., the text is “Unlocked”). In some embodiments, the uncompleted affordance 150c in the unlocked state has a display (e.g., brightness, transparency, saturation, contrast, or other visual features) different from the completed affordance 150a and the to-be-completed affordance 150b in visual impact.

[0097] Figure 5 The electronic device is shown in an exemplary interaction between a first user interface and a second control interface, Figure 6The interaction interface of the second control interface 120c is shown when the user selects the body part affordance 143b. In some embodiments, the home page of the display 101 provides affordances for list options (e.g., affordance 130a for "Regimen List" and affordance 130b for "My Plans"), through which the user enters the first user interface 110, in which the electronic device 100 displays affordances corresponding to different parts of the body and displays affordances that are freely selectable to indicate that the user can freely select and light output for any part of the body without having to separately perform control inputs associated with each part, simplifying the user's interaction with the interface and enabling the user to complete the operation of the part and the control in one interface, rather than having to follow, for example Figure 4E a sequence of unlocking each part through the list of regimen plans, or, for example Figure 2 the operation of the control after selecting the part. Displaying both types of affordances (the type of affordance for each part of the body and the type of freely selectable affordance) in the same user interface provides the user with a more flexible use and interaction experience.

[0098] In some embodiments, the user taps on the free selection affordance 140e, the electronic device 100 detects a second interface input 106 corresponding to the selection of the free selection affordance 140e in the first user interface 110, and the display 101 displays a second control interface 120c. In the second control interface 120c, the electronic device 100 displays in the scene section 126 affordances corresponding to different body parts (e.g., lip section affordance 143a, body part affordance 143b, underarm section affordance 143c, and / or private part affordance 143d) and provides textual and graphical representations of these representative body parts (e.g., the body part affordance 143b is associated with a body part graphical representation 1431 and a body part textual representation 1432). These different body part affordances have data and / or models of corresponding attributes of their associated body parts and related information, including but not limited to a unique identifier, a light pulse output parameter, a body part identifier, a pulse train interval duration, etc. In the second control interface 120c, the electronic device 100 displays in the function selection section 127 affordances corresponding to various execution functions of the light pulse device, including a first control affordance 121, a second control affordance 122, and a third control affordance. The first control affordance 121 corresponds to an option representation of the associated electronic device having an on / off SHR function. The first control affordance 121 includes a first control function switch representation 1211, which is lit when the current state is on and unlit when the current state is off. The second control affordance 122 includes a second control function switch representation 1221, which is associated with the display of the text representation “continuous flash” when activated and the text representation “single flash” when unactivated. The third control affordance includes a third control affordance 123a for energy reduction and a third control affordance 123b for energy increase, both of which can adjust the output parameter (e.g., pulse power and / or pulse width) of the pulse light upon corresponding user inputs.

[0099] In some embodiments, the electronic device 100 displays the body part affordance 143b as a visually altered effect (e.g., a change in brightness, transparency, saturation, contrast, or other visual characteristic) that is different from other body part affordances at the second control interface 120c in response to the user input of the body part affordance (e.g., body part) and informs the user of the correct representation of the input. The electronic device 100 takes the input of the body part affordance 143b and refreshes the pulse light output parameters (e.g., double pulse or six pulse, continuous flash or single flash, pulse power, and / or pulse width) corresponding to the multiple function switch representations (e.g., first control affordance 121, second control affordance 122, and third control affordance) associated with the function selection text representation 127. Subsequently, the user inputs a touch input (e.g., touching the display 101 to input the first control function switch representation 1211, the second control function switch representation 1221, and the third control affordance (123a, 123b)) according to the display state of the multiple function switch representations. Displaying multiple selectable body part affordances and multiple function switch representations at the same control interface provides a more convenient, free, and efficient control interface for the user, who does not need to select different body part corresponding function schemes through multiple hierarchical interfaces, which reduces the cognitive burden and operational complexity of the user.

[0100] Figure 7 An example interaction of the electronic device at the second user interface 111 and the first control interface 120a is shown. In some embodiments, the home page of the display 101 provides affordances of list options (e.g., the affordance of “Scheme List” 130a and the affordance of “My Plan” 130b), and the user inputs a touch input of the affordance of “My Plan” 130b to enter the second user interface 111, which includes a first body part information representation and a second body part information representation, the first body part information representation is associated with a command that is transmitted to the controllable external light pulse device to execute each time as a first function, the second body part information representation is associated with a command that is transmitted to the controllable external light pulse device to execute each time as a second function different from the first function; the second user interface input 107 in response to any selection of the first body part information representation and the second body part information representation; and the first control interface 120a is displayed on the display device according to the second user interface input 107.

[0101] In some embodiments, the second user interface 111 includes plan information associated with a plurality of body parts, and the associated part plan information can provide the user with a progress plan for each part treatment to provide more efficient interface interaction. For example, the second user interface 111 includes part information representations 144a-144b associated with each part to indicate information affordances 144al-144dl associated with the part information representations 144al-144dl to provide the user with a completion indication of the pulsed light execution plan for each part (e.g., with a textual representation of "rest" to inform the user that no light operation is needed for the part today, and / or a textual representation of "to be completed" to inform the user that the light operation can optionally be entered and completed today, and / or a textual representation of "completed" to inform the user that the light operation for the part has already been done today); and further includes progress affordances 144al-144dl to indicate the completion progress of each part, respectively (e.g., a textual representation of "completed 3 / 10 times"), and the electronic device and / or the light pulsed device can store the execution record after each pulsed light output by the user and update the display of the progress affordances 144al-144dl when the user enters the second user interface 111 next time. By interacting with the second user interface 111 and entering the first control interface 120a, the user is provided with a more abundant pulsed light execution interaction, and the interaction facilitates the user device to store the plan or the set plan to execute each pulsed light output, and the user is provided with a more flexible and efficient interaction experience.

[0102] Figure 8A - Figure 8B Exemplary control interfaces are shown in accordance with some embodiments. The user interfaces in these figures are used to illustrate the processes herein.

[0103] Figure 8AAn electronic device 200 with a display device 201 is shown. In some embodiments, the display device 201 displays a second control interface 210. At the second control interface 210, the electronic device 200 displays affordances corresponding to different body parts (e.g., lip area affordance 220a (partially shown), body part affordance 220b, underarm affordance 220c, and private part affordance 220d (partially shown)) that a user can control by swiping the touchscreen of the display device 201 to control the appearance and operation of the affordances for each of the different body parts. The affordances for these body parts are freely selectable and provide targeted light output to the user. The affordances for these different body parts have data and / or models and related information corresponding to attributes of their associated body parts, including but not limited to a unique identifier, light pulse output parameters, a body part identifier, an inter-pulse interval duration, etc. The second control interface 210 also displays a first control affordance 230, a second control affordance 240, and a third control affordance. The first control affordance 230 corresponds to an option to turn on / off the SHR function for the associated electronic device. The first control affordance 230 includes a first control function toggle 231 that is illuminated to indicate that the SHR mode is currently on and unilluminated to indicate that the SHR mode is currently off and that the light pulse device can only output a single pulse. The second control affordance 240 includes a second control function toggle 241 that, when activated, is associated with the display of the text “flash continuously” and, when unactivated, is associated with the display of the text “flash once.” The third control affordance includes a third control affordance 250a for decreasing the energy level and a third control affordance 250b for increasing the energy level, each of which can adjust the output parameters (e.g., pulse power and / or pulse width) of the pulse light upon user input.

[0104] In some embodiments, the electronic device 200 responds to the user's input of the body part affordance (e.g., underarm) at the second control interface 210, and displays the body part affordance 220c at the display device 201 with a visually changed effect (e.g., change in brightness, transparency, saturation, contrast, or other visual features) that is different from other body part affordances to inform the user of the correct representation of the input. The electronic device 200 obtains the input 108 of the body part affordance 220c and refreshes the pulse light parameters (e.g., double pulse or six pulse, continuous flash or single flash, pulse power, and / or pulse width) corresponding to the associated multiple function switch representations (e.g., the first control affordance 230, the second control affordance 240, and the third control affordance). Subsequently, the user makes touch inputs according to the display states of the multiple function switch representations (e.g., the first control function switch representation 231, the second control function switch representation 241, and the third control affordance (250a, 250b) at the display device 201). The simultaneous display of multiple selectable body part affordances and multiple function switch representations at the same control interface provides a more convenient, free, and effective control interface for the user, who does not need to select different body part corresponding function schemes through multiple hierarchical interface interactions, which reduces the user's cognitive burden and operational complexity. And applied to miniaturized electronic devices (e.g., watches), it is more convenient to improve the user's interaction convenience.

[0105] Figure 8B Another example of an electronic device 200 with a display device 201 is shown, which is communicatively connected with a light pulse device 300. Different from the previous embodiment, at the display device 201, the electronic device 200 obtains the input of the body part affordance 220b at the second control interface 210, which is further associated with the display of the graphical affordance 220b1 and the text representation 220b2 of the body part. At the same time, the first control function switch representation 231 is in the SHR off state, and the second control function switch representation 241 is in the continuous flash state.

[0106] In some embodiments, the light pulse device 300 releases high-energy light instantaneously through an internal xenon lamp, and transmits the light energy to the skin through a light-transmitting crystal, thereby achieving the purpose of hair removal and / or skin beautification.

[0107] Figure 9A partial structure example of a light pulsing device with a light-transmitting crystal is shown. The light pulsing device 300 is provided with one or more sensors 320 on the peripheral side of the light exit port of the light pulsing device 300, the sensors 320 are configured to be on the inside of the housing surface 311 or at least partially exposed to the outside, when a user holds the light pulsing device 300 and contacts the skin, the sensors 320 acquire contact signals and feed back to the processor of the light pulsing device 300. In some embodiments, the light pulsing device 300 automatically performs one or more light cycles of pulsed light according to the contact signals, for example, the light pulsing device receives a contact signal and outputs a light cycle of pulsed light and stops outputting until the user lifts the device and outputs again after detecting the contact signal next time.

[0108] Figure 10A A structure diagram showing that the sensors 320 are on the inside of the housing surface 311 is shown, Figure 10B A structure diagram showing that the sensors 320 are at least partially exposed is shown. In some embodiments, the light emitted by the light source is transmitted through the light exit surface 331 of the light-transmitting crystal 330 to irradiate the user's skin. The light exit surface 331 is arranged slightly protruding from the housing surface 311 to ensure that when the electronic device acquires contact signals through the sensors 320, the light exit surface 331 is in a close state of pressing the user's skin sufficiently. In some embodiments, the light exit surface 331 protrudes 1 mm from the housing surface 311.

[0109] In some embodiments, the light pulsing device 300 can include a capacitive contact sensor that converts a physical or mechanical quantity when contacting the skin into a capacitance change and transmits information to the light pulsing device to associate the output of pulsed light. The sensor 320 can include a force sensor (e.g., a strain gauge, a capacitive force sensor, a resistance force sensor), a touch sensor and / or a proximity sensor (such as a capacitive sensor), an optical sensor (such as an optical sensor that emits and detects light), a contact sensor, an ultrasonic sensor (e.g., an ultrasonic sensor for tracking the device direction and position and / or for detecting user input such as skin input), and / or other touch sensors and / or proximity sensors, monochrome and color ambient light sensors, image sensors, sensors for detecting position, orientation and / or motion (e.g., an accelerometer, a magnetic sensor (such as a compass sensor, a gyroscope and / or an inertial measurement unit containing part or all of these sensors)), an optical sensor (such as a self-mixing sensor that acquires time-of-flight measurements and a light detection and ranging (lidar) sensor), an optical sensor (such as a visual odometry sensor that uses images acquired by a digital image sensor in a camera to acquire position and / or direction information), a gaze tracking sensor, a visible light and / or infrared camera with a digital image sensor, a temperature and humidity sensor, a moisture content sensor and / or other sensors.

[0110] In some embodiments, the sensor 320 is arranged as a contact sensor, and the light pulsing device 300 triggers a continuous light output of one or more light cycles in response to each contact of the user's skin by the contact sensor. In some embodiments, the user contacts the light output port of the light pulsing device with the skin each time, and confirms the trigger signal through the contact sensor 320, thereby enabling the light pulsing device to perform a continuous light output of multiple light cycles when the light pulsing device contacts the user's skin multiple times, and each contact performs a light output of one light cycle (e.g., one light cycle performs a light output of six pulses, or one light cycle performs a light output of two pulses). In some embodiments, the surface of the housing of the light pulsing device is configured with a physical button that confirms the execution of the pulsed light. In the application scenario of triggering a continuous light output of one light cycle, the skin is contacted at the light output port, the light pulsing device receives the contact signal, at this time the light pulsing device does not output light, when the user presses the physical button, the light pulsing device outputs a light cycle of pulsed light and stops outputting, until the user removes the device and repeats the above operation form after the next contact of the skin at the light output port. In the application scenario of triggering a continuous light output of multiple light cycles, the skin is contacted at the light output port, the light pulsing device receives the contact signal, at this time the light pulsing device performs a light output of one light cycle according to the contact signal, stops and the user removes the device, as the user removes the device, the light pulsing device disconnects the received contact signal, the light pulsing device does not output light, until the next contact signal is received and a light output of one light cycle is performed, and the multiple times are continuously repeated.

[0111] In the following discussion, an output method of a light pulsing device is described.

[0112] The light pulsing device has a sensor to obtain a contact signal generated when the user contacts the skin, and based on the light output scheme stored in the light pulsing device and / or the light output scheme stored in the electronic device in communication connection therewith, the corresponding output of the pulsed light matched therewith is determined after the contact signal. In some embodiments, the light source uses a xenon lamp to provide the above-mentioned light, which releases pulsed light energy for acting on the target tissue after being excited by high voltage. In some embodiments, these lights release the above-mentioned energy in the form of a light pulse string (i.e., composed of multiple pulses) as a light cycle, and the configured light pulse string can act on the target tissue and achieve the desired purpose of light action.

[0113] In the prior art, a light pulse train in one light cycle has a form configured by two sub-pulses with increasing pulse energy values. The pulse energy value of each sub-pulse is determined by pulse power and time (i.e. pulse width), and the user releases energy to the skin by pulse light, which can penetrate the epidermis and reach the target tissue, and by acting on the target tissue with this part of energy, the purpose of hair removal and / or skin rejuvenation is achieved. With the release of energy in each light cycle, the higher the pulse energy value, the more obvious the user's body feeling (e.g. warm, tingling and / or burning), and no feeling or warm feeling is expected. The energy release of the double pulse sets the expected pulse train energy value to have two sub-pulses with gradient increasing, and after the first sub-pulse acts on the target tissue, the desired preheating is achieved, and after a desired pulse interval, the second sub-pulse with higher pulse energy value is released again, which can make the user receive the release with energy gradient increasing in one light cycle, thereby optimizing the body feeling (e.g. reducing tingling and / or burning). But this configuration scheme ignores the difference of the target tissue in different areas. For example, the light pulse device is a hair removal instrument, and since the human body has large differences in skin properties and / or hair properties at different parts (e.g. the hair around the lips is relatively sparse and soft, while the hair under the armpit is relatively hard), the prior art often configures the pulse energy value of the second sub-pulse to be higher to achieve the expected energy value to achieve the purpose of hair removal, or configures the first sub-pulse and the second sub-pulse to have higher pulse energy values to ensure that the total pulse energy value meets the purpose of hair removal, or in order to ensure comfort, the first sub-pulse and the second sub-pulse do not have higher pulse energy values, which makes the user need to perform multiple pulse light outputs on the same area. Obviously, no matter which way is implemented, when any one of the sub-pulses provides pulse light with high pulse energy to the target tissue, it will cause unexpected negative effects (e.g. tingling and / or burning) on the user's skin, which is caused by high pulse energy value pulse light, or the user cannot achieve the ideal hair removal purpose in one contact with the skin. For example Figure 11 As shown, Figure 11A schematic diagram of a double pulse in the prior art is shown. The double pulse is configured to have a pulse width of 0.3 ms, and to perform a pulse light energy release of a second sub-pulse with a pulse width of 6 ms after a pulse interval of 0.6 s. This configuration is proven to be effective for hair with sparse characteristics, but due to the low energy stacking value, and the second sub-pulse energy cannot provide an untimely higher energy, which may cause an unbearable stinging and / or burning sensation of the skin if designed to provide, so the double pulse cannot effectively deal with the hair area with coarse and hard properties. Therefore, the following provides an improvement on the configuration of the light pulse string and provides a light output method to release different light energy for different parts of the user's skin.

[0114] Specifically, in a light pulse string, the light pulse string is configured to continuously output N sub-pulse strings, each sub-pulse string has M sub-pulses, and each sub-pulse has a preset pulse energy value, which can be determined by the pulse power and the pulse width, N and M are both configured as integers greater than or equal to 2; in the N-1th sub-pulse string, the Mth sub-pulse has a first pulse energy value integral J1; in the Nth sub-pulse string, the Mth sub-pulse has a second pulse energy value integral J2; wherein J1

[0115] It should be noted that it is easy to think of stacking energy by multiple light pulse strings in sequence or by multiple sub-pulses in sequence, so the focus of the following discussion is not focused on this. Further, in a light pulse string, what needs to be demonstrated is the relationship between the N-1th sub-pulse string and the Nth sub-pulse string and the benefits provided by them.

[0116] In some embodiments, N and M are both configured as 2, i.e. the light pulse train in one light period can be referred to as "four-pulse", which is configured to continuously output two sub-pulse trains, each of which has two sub-pulses. It should be noted that the four sub-pulses constituted by the two sub-pulse trains should not be understood as the output of continuous pulse light formed by four sub-pulses, because the present application provides a limitation that the energy value of the Mth sub-pulse of the N-1th sub-pulse train is less than the energy value of the Mth sub-pulse of the Nth sub-pulse train. In other words, in the embodiment of four-pulse, the energy value of the second sub-pulse is limited to be less than the energy value of the fourth sub-pulse, which makes the first sub-pulse train release energy, and the second sub-pulse can have a less perceptible energy difference with the third sub-pulse, which is proved to be beneficial to the user's body feeling difference.

[0117] Figure 12 A pulse schematic diagram for performing "six-pulse" in one light period is shown. In the diagram, N is 2 and M is 3, which is configured to continuously output two sub-pulse trains, each of which has three sub-pulses, and the third sub-pulse has an energy value less than that of the sixth sub-pulse. In some embodiments, the pulse width of the six-pulse is 0.4ms, 0.5ms, 2ms, 0.4ms, 0.5ms and 6ms in turn, and the pulse interval in the first sub-pulse train 810 is 0.5s and 0.6s respectively, and the pulse interval in the second sub-pulse train 820 is 0.5s and 0.6s respectively. It should be noted that the foregoing definition of these sub-pulses as sub-pulse trains is because a sub-pulse train interval is provided between the adjacent two sub-pulse trains, and the sub-pulse train interval has a time length obviously different from the pulse interval, which has a non-negligible difference from the continuity of the six sub-pulses with the pulse interval. Specifically, the more obvious sub-pulse train interval can be used to provide the user with more time for the skin temperature to drop after experiencing the energy release of the first sub-pulse train, so as to ensure that the skin temperature is always within the skin damage threshold, while the target tissue temperature can still be maintained at a relatively ideal cumulative value, which makes the target tissue obtain the expected temperature after the energy accumulation of multiple sub-pulse trains, while the skin temperature is kept below the ideal temperature, bringing a better and more comfortable use experience. In some embodiments, the time length of the sub-pulse train interval is greater than 1s. More importantly, based on the user's use habits and the use effect brought to the user, such light pulse devices are more expected to complete the expected depilation and / or skin rejuvenation purpose in one light period, which puts forward more stringent design requirements for the one-time release of energy and the more comfortable use of the user.

[0118] The benefits of the sub-pulse train interval duration and the energy value of the Mth sub-pulse of the N-1th sub-pulse train being less than that of the Mth sub-pulse of the Nth sub-pulse train will be described in more detail below.

[0119] Figure 13 A comparison chart of the temperature curve of the prior art single pulse and the six-pulse of the present application is shown for the purpose of achieving the same target tissue temperature. Before explaining the comparison chart of the temperature curve, it is necessary to first understand the concept of "TRT (Thermal Relaxation Time)" involved in medical cosmetology, which refers to the time required for the target tissue to dissipate half of the heat absorbed by itself. In theory, the pulse width of each sub-pulse and the pulse interval between adjacent two sub-pulses in a light pulse train need to be greater than the TRT of the epidermis and less than the TRT of the target tissue, so as to ensure that the output energy can be completely absorbed by the target tissue without heat dissipation outward, and the epidermis has sufficient time to dissipate heat to avoid negative physical sensations (e.g., tingling and / or burning) caused by heat accumulation. Therefore, based on the concept of TRT and the above-mentioned one-time release of energy and user-unaware use, more stringent design requirements are proposed, i.e., a scheme of setting multiple light pulse trains in a light period and having a preset sub-pulse train interval duration.

[0120] As can be seen from the diagram, the single pulse can cause the target tissue temperature to rise to the ideal target temperature after releasing all the desired energy value of the pulse light at one time, but accompanied by a linear increase in the epidermis temperature and eventually exceeding the skin damage threshold. Generally speaking, when the ambient temperature is close to the human body temperature (36-37°C), the skin will have a slight hot and sticky feeling; when the heat source exceeds 44°C, it may cause low-temperature burns; in the temperature range of 45-60°C, long-term contact will cause progressive tissue damage; when it exceeds 50°C or above, short-term contact can cause skin damage (e.g., redness, tingling, etc.). Therefore, the form of providing a single pulse, or a sub-pulse with high energy in a pulse train for pulse light release is not acceptable.

[0121] As an improvement to address the epidermis temperature rise in single pulse application, the figure provides a six-pulse implementation that can provide an energy accumulation of the target tissue after the first sub-pulse train is released, and ensure that the epidermis temperature is within the skin damage threshold, further provides a sub-pulse train interval with a T2 (T2 > 1s) duration after the energy of the first sub-pulse train is released, the duration T2 of the sub-pulse train interval is significantly greater than the duration T1 of the inter-pulse interval between sub-pulses, which provides a longer epidermis temperature cooling time for the next sub-pulse train. Since the target tissue temperature also decreases with the duration of T2, the energy value of the Mth sub-pulse of the N-1th sub-pulse train is less than the energy value of the Mth sub-pulse of the Nth sub-pulse train, which makes it possible to achieve the expected target tissue temperature through the temperature rise of the Nth sub-pulse train energy release even after the target tissue has cooled down for the duration of T2 in the N-1th sub-pulse train. More specifically, within the same interval duration, the epidermis temperature has a faster cooling rate than the target tissue temperature, so when the T2 duration of the sub-pulse train interval, the epidermis temperature can be expected to have more temperature loss, and the target tissue temperature can have relatively less temperature loss.

[0122] As a comparative example, Figure 14A A comparative example is provided in which the energy values of the third sub-pulse and the sixth sub-pulse in the "six-pulse" are close. As can be seen in the figure, when the third sub-pulse 803 has an energy value close to that of the sixth sub-pulse 806, after the first sub-pulse train is released, the epidermis temperature has exceeded or is close to the skin damage threshold along with the high energy of the third sub-pulse. In actual use experience, the user will experience abnormal temperature sensation in the middle of a light cycle (e.g., an uncomfortable heating sensation on the skin); further, based on the energy accumulation of the first sub-pulse train, the target tissue temperature can reach the expected target value, while the epidermis temperature further exceeds the skin damage threshold. This is not the expected use experience.

[0123] Figure 14B A comparative example is provided in which the duration of the sub-pulse train interval in the "six-pulse" is too long. As can be seen in the figure, after the first sub-pulse train is released, the duration T2 of the sub-pulse train interval experienced is much greater than 1s, which makes both the epidermis temperature and the target tissue temperature experience a longer cooling duration, and after the second sub-pulse train is released, although the epidermis temperature is within the skin damage threshold, the target tissue temperature also decreases and cannot reach the expected temperature value. In actual use experience, the user will not easily perceive abnormal skin sensation in a light cycle, and the effectiveness of the light energy release is also not guaranteed. Therefore, in some embodiments, the sub-pulse train interval is set to: 1s ≤ T2 ≤ 1.5s, that is, T2 is set within a certain range to ensure the effectiveness of the light energy release.

[0124] Figure 14C A comparative example of a "six-pulse" neutron pulse train interval duration that is too short is provided. As can be seen in the illustration, after the first sub-pulse train releases energy, the sub-pulse train interval duration T2 experienced is much less than 1 s, which causes both the epidermis temperature and the target tissue temperature to experience a shorter cooling duration. After the second sub-pulse train is released, both the epidermis temperature and the target tissue temperature exceed the expected values. In actual use experience, the user will experience a stinging or burning sensation of the skin at the end of a light cycle.

[0125] In addition, according to the six-pulse scheme of Figure 12 , Figure 14A - Figure 14C , four energy release modes of the underarm part were provided to six subjects by the light pulse device, and the results shown in Figure 15 were obtained. As shown in Figure 15 , the subjects were provided with effective target tissue temperatures (shown as "√") using the corresponding pulse light embodiments according to Figure 12 , Figure 14A and Figure 14C , but Figure 14A and Figure 14C had more negative use feedback, such as obvious discomfort and unbearable pain. Figure 14B Although the corresponding scheme 3 had more good feedback from the user's body feeling, it could not reach the expected temperature of the target tissue, which was considered to be ineffective or inefficient energy release. The effectiveness of the user's body feeling or the target tissue temperature corresponding to scheme 1 had relatively better evaluation. Since the individual skin feeling is a subjective evaluation, the subjects will not have theoretically completely consistent evaluation results.

[0126] It can be understood that the number of sub-pulse trains can be increased or decreased according to the actual superposition value demand of the pulse energy, and can be two sub-pulse trains, three, four, etc., which makes a light cycle composed of multiple sub-pulse trains have more flexible energy release forms. In some embodiments, the more the number of sub-pulse trains, the smaller the energy value provided by each sub-pulse train can be adapted, thereby bringing more forms of energy gradient. For example, for the skin area with thick and hard hair, three or even four or more sub-pulse trains can be implemented in a light cycle. Through the energy gradient increment of the sub-pulse trains, on the one hand, the target tissue temperature accumulation effect brought by energy superposition can be achieved, and on the other hand, the user can be more easily adapted to the change brought by the temperature rise, providing a comfortable use experience. However, this will make the pulse light output of a light cycle have a perceptible extension, which also means that the number of sub-pulses and the number of sub-pulse trains need to be limited to a certain extent.

[0127] In some embodiments, in each sub-pulse train, there is a pulse interval T≥500 ms between the first sub-pulse and the second sub-pulse, and the length of time t1≤300 ms in the pulse interval for charging. This means that the pulse interval does not need to be entirely used to provide charging to the capacitance of the light pulse device, and since there are multiple pulse light intervals in one light period, this kind of embodiment can further optimize the charging and discharging form, thereby prolonging the service life of the capacitance.

[0128] In some embodiments, the Mth sub-pulse of the N-1th sub-pulse train has a first pulse energy value J1≤ half of the second pulse energy value J2 of the Mth sub-pulse in the Nth sub-pulse train, which means that J1 has a smaller energy gradient change value than the first sub-pulse in the Nth sub-pulse train, and a more comfortable use experience can be provided to the user in the light energy release.

[0129] In some embodiments, the sub-pulse interval T1 of the adjacent two sub-pulses in each sub-pulse train satisfies: 500 ms≤T1≤600 ms, which provides a reasonable charging time for the capacitance of the light pulse device.

[0130] In some embodiments, the pulse energy value of the Mth sub-pulse in each sub-pulse train is significantly greater than the pulse energy value of the other sub-pulses, which makes it possible to provide a transition energy release at the end of each sub-pulse train, which is conducive to the target tissue temperature to obtain temperature retention in a short time without being easily released by the pulse interval.
