Description

Technical Field

[0001] This invention relates to the field of intense pulsed light therapy technology, and more specifically, to an intense pulsed light therapy device based on energy homogenization technology and its time-division control method. Background Technology

[0002] In current traditional intense pulsed light (IPL) therapy devices, the capacitor-based energy storage and discharge method often suffers from inconsistent energy levels in each pulse due to the capacitor's charging speed failing to keep pace with its discharge speed. This is especially true for consecutive pulses, where the energy difference between pulses widens significantly, severely impacting the overall effect. Furthermore, prolonged treatment can lead to energy loss, resulting in less noticeable post-treatment effects and the need for multiple treatments.

[0003] Therefore, in practical applications, it is necessary to solve the problem of inconsistent output pulse energy. Summary of the Invention

[0004] To address the aforementioned technical problems in related technologies, this invention proposes a high-intensity pulsed light therapy device based on energy homogenization technology. This device solves the problem of unstable energy output in traditional high-intensity pulsed light, optimizes the energy spikes at the beginning and end of the pulse, and overcomes the above-mentioned deficiencies of the prior art.

[0005] To achieve the above-mentioned technical objectives, the technical solution of the present invention is as follows: The first objective of this invention is to provide a high-intensity pulsed light therapy device based on energy homogenization technology, comprising a central processing unit connected to the input terminal of a power supply unit, the power supply unit comprising a plurality of power supplies connected in parallel; the positive and negative terminals of each power supply output terminal are connected to the positive and negative terminals of a capacitor unit, each capacitor unit comprising a plurality of capacitors connected in series; the positive terminal of each capacitor unit is further connected to the input terminal of a control switch, the output terminal of each control switch is connected to the positive terminal of a unidirectional power semiconductor device, the negative terminal of each unidirectional power semiconductor device is connected to the positive terminal of a xenon lamp, and the negative terminal of each capacitor unit is further connected to the negative terminal of the xenon lamp; simultaneously, the central processing unit is connected to each of the control switches.

[0006] Furthermore, the number of power supplies included in the power supply unit depends on actual needs, and preferably includes 3 power supplies.

[0007] Furthermore, the number of capacitors included in each capacitor unit depends on actual needs, and preferably includes 3 capacitors.

[0008] Furthermore, the unidirectional power semiconductor device is preferably a diode, depending on the actual needs.

[0009] Furthermore, the central processing unit (1) is determined according to actual needs, and is preferably an MCU central processing unit.

[0010] The second objective of this invention is to provide a time-sharing control method for a high-intensity pulsed light therapy device based on energy homogenization technology, as mentioned in the first objective. This time-sharing control method uses a central processing unit 1 to coordinate and control all the power supplies 2 and the control switches 4. Each group of capacitor units 3 simultaneously supplies power to the xenon lamp 6 when discharging. Specifically, the method includes the following steps: Step S1: Each power source 2 charges its corresponding connected capacitor unit 3. The control switch 4 connected to the capacitor unit 3 during charging is simultaneously disconnected, thereby ensuring that the charging and discharging operations of each capacitor unit 3 are not performed at the same time, and the duration of the discharge cycle of each group of capacitor units 3 is consistent. Step S2: When power is supplied, the control switch 4 connected to the capacitor unit 3 in the first group is closed and discharged; Step S3: After the first group of capacitor units 3 has completed discharging, the control switch 4 connected to it is disconnected, the first group of capacitor units 3 stops discharging and is recharged by the power supply 2 corresponding to it; the control switch 4 connected to the second group of capacitor units 3 is closed synchronously and discharged. Step S3: After the second group of capacitor units 3 has completed discharging, the control switch 4 connected to it is disconnected, the second group of capacitor units 3 stops discharging and is recharged by the power source corresponding to it; the control switch 4 connected to the third group of capacitor units 3 is closed synchronously and discharges. Step S4: After the previous group of capacitor units 3 has finished discharging, the control switch 4 corresponding to the previous group of capacitors 3 is disconnected and recharged by the power supply 2 corresponding to it. Then the control switch 4 corresponding to the next group of capacitor units 3 is closed and discharged. This process continues until the last group of capacitor units 3 has finished discharging. Step S5: Repeat steps S2-S4.

[0011] In a specific embodiment of the present invention, under the unified coordination and control of the central processing unit, only one control switch connected to the capacitor unit is closed in each discharge cycle, that is, only one set of capacitor units discharges in each discharge cycle.

[0012] The beneficial effects of this design are as follows: This product overcomes the instability of energy output in traditional intense pulsed light (IPL) by optimizing the energy peaks at the beginning and end of the pulse. This design utilizes energy homogenization technology to ensure balanced and uniform energy output throughout the emitted pulse wave. Through sequential pulse waves, photon energy is continuously and uniformly applied to the skin, allowing the skin to quickly absorb sufficient energy, avoiding thermal damage, reducing pain during treatment, and promoting skin regeneration imperceptibly. This product eliminates energy peaks and thus energy decay, while retaining relatively effective energy. Compared to existing technologies, the safety and effectiveness of treatment are significantly improved. Attached Figure Description

[0018] like Figure 1-2 As shown, in order to facilitate understanding of the above technical solutions of the present invention, the following describes the above technical solutions of the present invention in detail through specific usage methods.

[0019] The first objective of this invention is to provide a high-intensity pulsed light therapy device based on energy homogenization technology, comprising a central processing unit 1 connected to the input terminal of a power supply unit, the power supply unit comprising a plurality of power supplies 2 connected in parallel; the positive and negative terminals of the output terminals of each power supply 2 are connected to the positive and negative terminals of a capacitor unit 3, each capacitor unit 3 comprising a plurality of capacitors connected in series; the positive terminal of each capacitor unit 3 is further connected to the input terminal of a control switch 4, the output terminal of each control switch 4 is connected to the positive terminal of a unidirectional power semiconductor device 5, the negative terminal of each unidirectional power semiconductor device 5 is connected to the positive terminal of a xenon lamp 6, and the negative terminal of each capacitor unit 3 is further connected to the negative terminal of the xenon lamp 6; simultaneously, the central processing unit 1 is connected to each of the control switches 4.

[0020] In one specific embodiment of the present invention, the number of power supplies 2 included in the power supply unit depends on actual needs, and preferably includes 3 power supplies 2.

[0021] In one specific embodiment of the present invention, the number of capacitors included in each capacitor unit 3 depends on actual needs, and preferably includes 3 capacitors.

[0022] In one specific embodiment of the present invention, the unidirectional power semiconductor device 5 is determined according to actual needs, and is preferably a diode.

[0023] In one specific embodiment of the present invention, the central processing unit 1 is determined according to actual needs, and is preferably an MCU central processing unit.

[0024] The second objective of this invention is to provide a time-sharing control method for a high-intensity pulsed light therapy device based on energy homogenization technology, as mentioned in the first objective. This time-sharing control method uses a central processing unit 1 to coordinate and control all the power supplies 2 and the control switches 4. Each group of capacitor units 3 simultaneously supplies power to the xenon lamp 6 when discharging. Specifically, the method includes the following steps: Step S1: Each power source 2 charges its corresponding connected capacitor unit 3. The control switch 4 connected to the capacitor unit 3 during charging is simultaneously disconnected, thereby ensuring that the charging and discharging operations of each group of capacitor units 3 are not performed at the same time, and the duration of the discharge cycle of each group of capacitor units 3 is consistent. Step S2: When power is supplied, the control switch 4 connected to the capacitor unit 3 in the first group is closed and discharged; Step S3: After the first group of capacitor units 3 has completed discharging, the control switch 4 connected to it is disconnected, the first group of capacitor units 3 stops discharging and is recharged by the power supply 2 corresponding to it; the control switch 4 connected to the second group of capacitor units 3 is closed synchronously and discharged. Step S3: After the second group of capacitor units 3 has completed discharging, the control switch 4 connected to it is disconnected, the second group of capacitor units 3 stops discharging and is recharged by the power supply 2 corresponding to it; the control switch 4 connected to the third group of capacitor units 3 is closed synchronously and discharges. Step S4: After the previous group of capacitor units 3 has finished discharging, the control switch 4 corresponding to the previous group of capacitor units 3 is opened, and the previous group of capacitor units 3 is recharged by the power supply 2 corresponding to it. Then the control switch 4 corresponding to the next group of capacitor units 3 is closed and discharged; and so on, until the last group of capacitor units 3 has finished discharging. Step S5: Repeat steps S2-S4.

[0025] In a specific embodiment of the present invention, under the unified coordination and control of the central processing unit 1, only one set of control switches 4 connected to the capacitor unit 3 is closed in each discharge cycle, that is, only one set of capacitor units 3 is discharged in each discharge cycle.

[0026] Specific working principle: This invention includes a power supply unit 2 comprising multiple parallel power supplies. Each power supply corresponds to a capacitor unit 3, a control switch 4, and a unidirectional power semiconductor device 5, thus forming multiple sets of charging and discharging control circuits. Under the unified and coordinated control of all power supplies and control switches 4 by the central processing unit 1, each set of capacitor units 3 is charged by its corresponding power supply, and then each set of capacitor units 3 sequentially discharges in turn. The discharge operation of each set of capacitor units 3 also simultaneously supplies power to the xenon lamp 6. The discharge cycle duration of each set of capacitor units 3 is consistent, thereby ensuring the consistency of the charge and discharge capacity of different capacitor units 3 and avoiding the generation of energy spikes. After the first set of capacitor units 3 has finished discharging, its corresponding control switch 4 is opened and it is recharged by its corresponding power supply 2; the control switch 4 corresponding to the second set of capacitor units 3 is closed and it discharges; and so on, until the last set of capacitor units 3 has finished discharging. At the same time, the other capacitor units 3 that have been discharged are continuously charged to compensate for the defect that the charging speed is less than the discharging speed, thereby avoiding the problem of inconsistent energy in each discharge. In simple terms, when each control switch 4 is closed, its corresponding capacitor unit 3 discharges; when each control switch 4 is open, its corresponding capacitor unit 3 is charged by its corresponding power supply 2.

[0027] In summary, this design, employing the aforementioned unique design principles, overcomes the instability of energy output in traditional intense pulsed light (IPL) by optimizing the energy peaks at the beginning and end of the pulse. This design utilizes energy homogenization technology to ensure balanced and uniform energy output throughout the emitted pulse wave. Through sequential pulse waves, photon energy is continuously and uniformly applied to the skin, allowing for rapid absorption of sufficient energy, preventing thermal damage, reducing pain during treatment, and promoting skin regeneration imperceptibly. This product eliminates energy peaks and thus energy decay, while retaining relatively effective energy. Compared to existing technologies, the safety and effectiveness of treatment are significantly improved.
