Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

[0036] To facilitate understanding of this embodiment, the application scenarios and design concepts of this application embodiment will be briefly introduced below.
[0037] During phototherapy, the safety of the treatment is affected by a variety of factors. Therefore, there is an urgent need for a phototherapy device that can improve the safety of phototherapy.
[0038] Example 1
[0039] This application provides a phototherapy device. Please refer to... Figure 1 , Figure 1 This is a schematic diagram showing the connections of the internal modules of the phototherapy device provided in this application. The phototherapy device includes a control module 1, a multi-dimensional detection module, and a light source module 2. The light source module 2 and the multi-dimensional detection module are respectively connected to the control module 1; the multi-dimensional detection module includes at least a temperature detection module 3.
[0040] The light source module 2 is configured to emit light of different wavelengths under the control of the control module 1.
[0041] The control module 1 is configured to: control the phototherapy device to reduce its frequency when the real-time temperature of the irradiated skin surface collected by the temperature detection module 3 is greater than a first temperature threshold; and control the phototherapy device to stop operating when the real-time temperature is greater than a second temperature threshold. The first temperature threshold is less than the second temperature threshold.
[0042] The phototherapy device provided in this application has a multi-dimensional detection module, which can perform detection from multiple dimensions to improve the operational safety of the phototherapy device, and adjust the operating mode of the phototherapy device based on the comparison between the detected real-time temperature and two temperature thresholds.
[0043] Combination Figure 2 As shown, the phototherapy device also includes a lamp head assembly 7, which includes multiple lamp heads. Each lamp head has a light source module 2. All the light source modules 2 are connected to the control module 1, so that under the control of the control module 1, multiple different light sources (i.e., light waves of different wavelengths) are output, thereby realizing multi-source light output.
[0044] In conjunction with the first aspect, the phototherapy device includes a control module 1, a multi-dimensional detection module, a light source module 2, and a prompting module 4. The light source module 2, the prompting module 4, and the multi-dimensional detection module are respectively connected to the control module 1. The multi-dimensional detection module includes at least a temperature detection module 3 and a light intensity detection module 5.
[0045] The light intensity detection module 5 is configured to detect the irradiance of the light emitted by the phototherapy device. The light intensity detection module 5 and the prompting module 4 are respectively connected to the control module 1.
[0046] The control module 1 is also configured to send a prompt command to the prompt module 4 when the irradiance collected by the light intensity detection module 5 decays to a specified value, thereby controlling the prompt module 4 to issue a prompt. Specifically, the prompt is a voice prompt. It should be noted that the prompt is not limited to a voice prompt; it can also be other prompts, such as flashing fault codes on the operation panel or synchronized flashing of ambient lights.
[0047] In this embodiment, the multi-dimensional detection module includes at least a temperature detection module 3 and a light intensity detection module 5, which detects at least two dimensions: the light irradiation intensity and the real-time temperature of the light on the user's skin, in order to improve the safety and effectiveness of the phototherapy device.
[0048] The light intensity detection module 5 measures the irradiance of the light emitted by the phototherapy device. When the intensity decreases to a specified value, it indicates that the LED beads in the light source module need to be replaced. At this time, the control module 1 generates an instruction and sends it to the prompt module 4 for voice prompts, so that the administrator of the phototherapy device can replace the light source module in time to improve the effectiveness of the phototherapy device.
[0049] Specifically, the light intensity detection module 5 determines the illumination level by measuring the intensity of light (i.e., luminous flux). The light intensity detection module 5 uses a built-in photosensitive element. When light from the light source module 2 shines on the photosensitive element, it generates electrical signals of varying intensities based on the light intensity. This electrical signal is processed internally by the light intensity module and ultimately converted into a light intensity value, which is then fed back to the microcontroller unit of the control device. In this embodiment, the control module 1 acquires the smoothed and filtered light intensity value at 1-second intervals. If the light intensity value acquired 10 times consecutively is lower than a specified value (i.e., a preset light intensity alarm threshold), the light source module 2 continues to output a treatment signal, the digital tube outputs a fault code, and further, the ambient light can be controlled to flash orange-yellow synchronously at 1Hz and written into the fault log, thereby detecting the light intensity output by the light source module 2.
[0050] In conjunction with the first aspect, the phototherapy device includes a control module 1, a multi-dimensional detection module, a light source module 2, and a prompting module 4. The light source module 2, the prompting module 4, and the multi-dimensional detection module are respectively connected to the control module 1. The multi-dimensional detection module includes at least a temperature detection module 3, a light intensity detection module 5, and a distance detection module 6.
[0051] The distance detection module 6 is configured to detect the real-time distance between the light emitting surface of the phototherapy device and the user's skin surface. The distance detection module 6 is connected to the control module.
[0052] The control module 1 is also configured to send a prompting command to the prompting module 4 when the real-time distance collected by the distance detection module 6 exceeds the preset distance range, so as to control the prompting module 4 to issue a voice prompt.
[0053] In this embodiment, the multi-dimensional detection module includes at least a temperature detection module 3, a light intensity detection module 5, and a distance detection module 6. It detects at least three dimensions: light irradiation intensity, real-time temperature of the light on the user's skin, and real-time distance between the light emitting surface and the skin surface, in order to improve the safety and effectiveness of the phototherapy device.
[0054] Among them, if the real-time distance collected by the distance detection module 6 exceeds the preset distance range, that is, if it is too close to the user's skin, the control module 1 generates an instruction and sends it to the prompt module 4 to provide a voice prompt, so that the administrator of the phototherapy device can adjust the light source module 2 in time.
[0055] In conjunction with the first aspect, the phototherapy device also includes the connected therapy device body 9 and lamp head assembly 7. The light source module 2, temperature detection module 3, light intensity detection module 5, and distance detection module 6 are respectively integrated on the circuit board inside the lamp head assembly.
[0056] Combination Figure 2 As shown, the lamp head assembly 7 is connected to the therapeutic device body 9 via a connector 8. This connector 8 is typically L-shaped to allow the user to receive light therapy while lying down. Preferably, the connector 8 may include multiple sub-connectors with multiple degrees of freedom, such as a telescopic rod with a limiting mechanism, enabling height-direction position adjustment. The lamp head assembly 7 is connected to the end of the connector 8, and the lamp head assembly 7 includes multiple electrically connected lamp heads. It is understood that the control module 1 is also built on one or more PCBAs.
[0057] Understandably, this application also includes a power supply module, which uses an independent power supply to power the light source module 2. In this embodiment, a 48V constant voltage power supply module is selected, and a brand-new constant voltage drive control system is adopted. Independent control of the light source module 2 in different lamp heads is achieved through independent drive circuits, without adding additional detection circuits and other accessories for the phototherapy device itself, thus using the fewest possible system-level components.
[0058] Please refer to Figure 3 , Figure 3 This is an exploded view of a single lamp head in the lamp head assembly 7. The light source module 2, temperature detection module 3, light intensity detection module 5, and distance detection module 6 are integrated on the circuit board. In this embodiment, the temperature detection module 3 and distance detection module 6 are located on the same side. On the other side, symmetrical with respect to the center line, a light intensity detection module 5 is also provided. Below this is the light source module 2, which is a matrix arrangement of LED beads.
[0059] Combination Figure 3 As shown, a heat dissipation module 12 is also provided above the light source module 2 to dissipate the heat generated during operation. The heat dissipation module 12 is connected to a drive unit, which can be electrically connected to the control module 1 so that the control module 1 can start the drive unit, thereby turning on the heat dissipation module 12.
[0060] In conjunction with the first aspect, the phototherapy device also includes: a laser module 10, which is located inside the lamp head assembly 7 and connected to the control module 1.
[0061] Understandably, the laser module 10 inside the lamp head assembly 7 generates laser light for positioning during phototherapy.
[0062] In conjunction with the first aspect, the treatment device body 9 is also provided with a mobile terminal housing 91, on which a mobile terminal is detachably installed, and the mobile terminal is communicatively connected to the control module 1.
[0063] Please refer to Figure 2 A mobile terminal housing 91 is provided on the side of the treatment device body 9 away from the lamp head assembly 7. The prompt module 4 can be integrated into the mobile terminal or set on the treatment device body 9. During phototherapy, the lamp head assembly 7 is close to and faces the user's skin, and the mobile terminal faces the administrator. The mobile terminal has a display module that can display the data detected by the multi-dimensional detection module, and can also be used to display various operating parameters during phototherapy, such as the operating power of the light source module 2.
[0064] In conjunction with the first aspect, the temperature detection module 3 is an infrared temperature sensing element.
[0065] In this embodiment, by receiving the infrared radiation energy emitted from the patient's treatment area and calculating it according to the blackbody radiation law, the skin temperature value can be obtained. The skin temperature detection module feeds back the temperature value to the microcontroller unit of the control device, thereby detecting the patient's skin temperature. When the patient's skin temperature exceeds a first temperature threshold, the energy level of the treatment light source is automatically reduced; when the patient's skin temperature exceeds a second threshold, the light therapy is stopped. This allows for different adjustments based on different situations. In cases where the skin temperature is high but does not exceed a preset value, adjustment is made first, rather than directly shutting down the light therapy device, to avoid interruptions in the light therapy process. This reduces the possibility of energy loss and damage to the light therapy device due to accidental triggering or frequent shutdowns.
[0066] In conjunction with the first aspect, distance detection module 6 is an ultrasonic detection module. It employs a non-contact distance detection method to detect the distance between the light-emitting surface and the user's skin. Utilizing ultrasonic ranging technology, its working principle is based on the characteristics of ultrasound waves; that is, ultrasound waves travel at a constant speed in the air. The distance traveled by the ultrasound wave is calculated by multiplying the speed of sound by time. The ultrasonic ranging module includes an ultrasonic transmitter and a receiver to measure the time elapsed from the emission of the ultrasonic wave to the reception of the reflected wave. Using the distance calculation formula: distance = speed of sound × time, the distance traveled by the ultrasonic wave is calculated (where the speed of sound is a known 343 m / s, and time is the total time from the emission of the ultrasonic wave to the reception of the reflected wave. Since the speed of ultrasonic wave propagation is much greater than the measurement time, the emission and reception can be considered instantaneous; therefore, the measurement time is actually the round-trip time of the ultrasonic wave). The ultrasonic ranging module feeds back the calculated distance value to the microcontroller unit of the control device. The distance value after smoothing and filtering is obtained from the drive control system at 1-second intervals. The detection cycle is 30 seconds / time. If the distance is lower than the threshold at least 10 times within the 30-second detection cycle, the control prompt module 4 will announce "treatment distance is too close" in voice, thereby detecting the treatment distance output by the light source.
[0067] In conjunction with the first aspect, the phototherapy device also includes: a pulse rate detection module 11, which is located on the main body 9 of the therapy device and connected to the control module 1.
[0068] Please refer to Figure 2 A pulse rate detection module 11 is installed on the main body 9 of the therapeutic device to detect the user's pulse rate in real time. In the event of an abnormal pulse rate during phototherapy, the module 4 is activated to provide voice or audio-visual prompts. Preferably, the control module 1 is also configured to stop the phototherapy device when an abnormal pulse rate occurs. Furthermore, the control module 1 is also configured to send communication commands to a mobile terminal with which it is connected to automatically dial an emergency call.
[0069] Secondly, this application provides a phototherapy system, including a main control unit and at least one phototherapy device as described above, wherein the main control unit is communicatively connected to the control modules of all phototherapy devices.
[0070] In this way, the main control unit can communicate with the control modules of multiple phototherapy devices to achieve overall management of multiple phototherapy devices through the main control unit. Multiple phototherapy devices can be applied to different skin surfaces of the user in batches or simultaneously to improve the efficiency of phototherapy.
