Currently, physiotherapy lamps are widely used in rehabilitation therapy departments and home healthcare.

[0003] However, most existing physiotherapy lamps require patients or operators to manually adjust the treatment distance or power level according to their own needs. If the irradiation distance is too close, it may lead to excessive local irradiation intensity, causing skin burns or discomfort; if the irradiation distance is too far, it may affect the treatment effect due to insufficient irradiation intensity. Especially when patients use them alone or have difficulty moving around, it is difficult to maintain a suitable treatment distance in real time, resulting in poor ease of use.

[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] This invention provides a physiotherapy lamp, such as... Figure 1-6 As shown, the physiotherapy lamp includes: a support rod 2; a light wave therapy head 3 mounted on the support rod 2; a distance detector 4 disposed on the light wave therapy head 3 for detecting the distance between the light wave therapy head 3 and the treatment area, and outputting distance data; and a processor communicatively connected to the distance detector 4, the processor being configured to receive the distance data and automatically adjust the working power of the light wave therapy head 3 according to the distance value corresponding to the distance data.

[0021] In this embodiment, ultrasonic pulses are emitted to the treatment area in real time by the distance detector 4, and the reflected echoes are received. By measuring the time difference between emission and reception, and combining the sound speed, the current irradiation distance between the light wave therapy head 3 and the human body is calculated in real time. This distance data is transmitted to the processor (not shown in the figure) in real time. When the patient's body position changes (such as unconscious body movement or a change in sitting posture), causing a change in the irradiation distance, the processor automatically adjusts the output power of the light wave therapy head 3 according to the preset safety and treatment curves: when the distance is too close, the power is automatically reduced to prevent skin burns; when the distance is too far, the power is automatically increased to ensure the treatment effect, thereby realizing fully automatic closed-loop control. After the treatment is completed, the device is turned off by the processor. The distance detector 4 transmits ultrasonic pulses or radar waves to the treatment area in real time and receives the reflected echoes. The processor calculates the current irradiation distance between the light wave therapy head 3 and the human body in real time based on the time difference between transmission and reception. When the irradiation distance changes due to changes in the patient's body position, the processor can automatically adjust the output power of the light wave therapy head 3 according to the preset safety and treatment curves to ensure that the treatment effect does not decrease due to changes in distance. This achieves dynamic matching of irradiation dose and distance during treatment without repeated manual intervention.

[0022] In a further preferred embodiment of the present invention, the physiotherapy lamp further includes a handle 5 disposed on the top of the light wave therapy head 3. The handle 5 has a hollow structure for the user to hold. The distance detector 4 is installed on the side of the handle 5 near the air outlet, and a wiring groove is provided inside the handle 5 for the power cord of the distance detector 4 to pass through.

[0023] In this embodiment, the physiotherapy lamp also includes a handle 5 located on the top of the light wave therapy head 3, to facilitate the user in adjusting the irradiation angle of the therapy head or moving the device. The handle 5 is positioned entirely above the light wave therapy head 3 and features an ergonomic design. The handle 5 has a hollow structure to reduce overall weight and create a space for the user to hold, thereby improving grip comfort and ease of operation.

[0024] The distance detector 4 is fixedly installed on the side of the handle 5 near the air outlet. This position ensures that the detection direction of the distance detector 4 is basically consistent with the irradiation direction of the treatment head while ensuring that the detection field of view is not obstructed, thus more accurately reflecting the actual distance between the treatment head and the irradiated object. At the same time, this installation position is away from the fan 33 and the main heat source area on the side of the air inlet, which helps to reduce the impact of ambient temperature on the measurement accuracy of the distance detector 4.

[0025] The handle 5 also has a cable routing channel inside, which is arranged along the extension direction of the handle 5 and runs through the interior of the handle 5, for the power cable of the distance detector 4 to be run and arranged. The cable routing channel not only realizes the concealed routing of the power cable, avoiding the wires from being exposed and affecting the appearance or being accidentally pulled, but also enables the handle 5 to have the functions of cable management and installation positioning in its structure, improving the neatness and reliability of the overall assembly.

[0026] In a further preferred embodiment of the present invention, the support rod 2 is a gooseneck tube, a serpentine tube, or a rod-shaped structure supported by shape memory metal, and the support rod 2 can achieve stepless adjustment of the degree of bending.

[0027] In this embodiment, the user holds the light wave therapy head 3 or the handle 5 and bends the support rod 2 directly in the desired direction. Since the support rod 2 is made of gooseneck tube, serpentine tube or memory metal, it is malleable and can maintain its deformed posture. Therefore, the user can achieve stepless adjustment of the support rod 2 at any angle and any curvature without the aid of tools. After adjustment, the stable irradiation posture of the light wave therapy head 3 is maintained by the self-locking characteristics of the structure, which further makes up for the insufficient angle coverage of simple rotation connection in complex body positions.

[0028] In a further preferred embodiment of the present invention, the physiotherapy lamp further includes a counterweight base 1, the top of which is assembled with the end of the support rod 2 away from the light wave therapy head 3.

[0029] In this embodiment, the counterweight base 1 is placed on the ground or tabletop. Utilizing its large mass and low center of gravity, it provides stable support for the upper support rod 2 and the light wave therapy head 3. When the user manually adjusts the position of the light wave therapy head 3 or an accidental bump occurs during treatment, the counterweight base 1 can resist the overturning torque and prevent the entire physiotherapy lamp from tipping over.

[0030] In a further preferred embodiment of the present invention, the light wave therapy head 3 is rotatably connected to the support rod 2 so that the angle of the light wave therapy head 3 can be adjusted; The light wave therapy head includes: a housing 31, with an air inlet and an air outlet on each side of the housing 31; a light source emitter 32 installed inside the housing 31, positioned between the air inlet and the air outlet; a fan 33 installed at the air inlet and facing the air outlet; and a heat insulation cover 34 installed inside the housing 31 and covering the outside of the light source emitter 32.

[0031] Specifically, the light wave therapy head 3 includes a housing 31, with an air inlet and an air outlet on each side of the housing 31, arranged in a convection pattern to form an airflow channel. Inside the housing 31, between the air inlet and the air outlet, is a light source emitter 32, which emits therapeutic light waves towards the target object. A fan 33 is installed at the air inlet, facing the air outlet. During operation, the fan draws in cool external air through the air inlet, flows over the surface of the light source emitter 32, and exhausts heat through the air outlet, thus achieving active air cooling.

[0032] Furthermore, a heat insulation cover 34 is provided inside the outer casing 31. The heat insulation cover 34 covers the outside of the light source emitter 32 and separates the light source emitter 32 from the inner wall of the outer casing 31. The heat insulation cover 34 can, on the one hand, prevent the radiant heat generated by the light source emitter 32 from being directly conducted to the outer casing 31, reducing the temperature rise of the outer casing 31, and on the other hand, guide the airflow to concentrate and flow across the surface of the light source emitter 32, improving the heat dissipation efficiency.

[0033] When the processor detects that the distance data is less than a preset threshold and controls the light source emitter 32 to stop working or enter a power reduction mode, the fan 33 can be configured to continue running or adjust its speed according to temperature feedback to accelerate the dissipation of residual heat and prevent user burns or device aging caused by heat accumulation. In addition, the heat shield 34 ensures that the housing 31 can still be kept within a safe temperature range in the event of an emergency shutdown due to abnormal distance, further enhancing the passive safety of the equipment.

[0034] In this embodiment, after the support rod 2 completes coarse positioning, the user holds the handle 5 or the housing of the light wave therapy head 3, overcoming the damping force at the rotating connection, causing the light wave therapy head 3 to pitch and rotate relative to the support rod 2 around a horizontal axis or a ball joint. The rotating connection structure, in conjunction with the bending function of the support rod 2, achieves two-stage angle fine adjustment: the support rod 2 is responsible for large-scale spatial positioning, while the rotating connection is responsible for the fine alignment of the therapy head with the treatment area of ​​the human body, thereby ensuring that infrared radiation or ultrasound can irradiate the target treatment area vertically or at the optimal angle.

[0035] In a further preferred embodiment of the present invention, the physiotherapy lamp further includes a gyroscope or tilt switch installed on the support rod 2 and communicatively connected to the processor. The gyroscope or tilt switch is used to send a power-off signal to the processor when the physiotherapy lamp is detected to be tilted, so that the processor can forcibly control the physiotherapy lamp to be powered off.

[0036] In this embodiment, the gyroscope collects the attitude angle data (such as pitch angle and roll angle) of the support rod 2 in three-dimensional space in real time and continuously compares it with the preset safety angle threshold in the processor. When the user accidentally adjusts the support rod 2 to the extreme tilt angle (e.g., greater than 70°), or when the device's center of gravity deviates significantly due to an external impact, the gyroscope determines that there is a risk of tipping over and immediately sends a power-off signal to the processor. After receiving the signal, the processor forcibly cuts off the power supply to the light wave therapy head 3, regardless of whether the treatment is currently in progress, to prevent heat radiation burns to surrounding objects or short circuits caused by tipping over.

[0037] In a further preferred embodiment of the present invention, the physiotherapy lamp further includes a voice control module communicatively connected to the processor. The voice control module is used to receive user voice commands and coordinate with the processor to output control commands to control the operation of the physiotherapy lamp.

[0038] In this embodiment, the voice control module has a built-in microphone that collects voice signals from the environment in real time and parses semantic commands (such as increasing power, turning off treatment, or setting a timer for 30 minutes) through a local or cloud-based voice recognition algorithm. The recognized commands are transmitted to the processor, which calls the corresponding control program based on the command to automatically adjust the output power level, start / stop status, or remaining treatment time of the light wave therapy head 3, thereby freeing the user's hands. This is especially suitable for scenarios where the user's hands cannot operate the control panel during treatment, such as lower back treatment.

[0039] In a further preferred embodiment of the present invention, the light wave therapy head 3 is an infrared therapy head or a red light therapy head, or a specific electromagnetic wave therapy head.

[0040] In this embodiment, the appropriate type of physiotherapy device is selected according to different clinical treatment needs. The closed-loop control logic of the distance detector 4 and the processor is also applicable to the above-mentioned treatment heads, that is, it automatically adjusts the ultrasonic amplitude or light radiation intensity according to the distance change to match the safety and effective dosage requirements under different treatment principles.

[0041] In a further preferred embodiment of the present invention, the distance detector 4 is an ultrasonic sensor, a radar detector, or a laser detector; The installation angle between the distance detector 4 and the light wave therapy head 3 is 15°; the detection range of the distance detector 4 in the horizontal direction is -15° to 15°; the detection range of the distance detector 4 in the vertical direction is -30° to 30°.

[0042] In this embodiment, when an ultrasonic sensor is used as the distance detector 4, it emits ultrasonic pulses of 40kHz-200kHz and receives the echoes reflected by the human body. The processor calculates the accurate distance value based on the round-trip time difference of the sound waves and the known speed of sound. When a radar detector (such as a millimeter-wave radar) is used, it emits frequency-modulated continuous waves of 60GHz-120GHz and measures the distance by detecting the frequency difference and phase change of the reflected signals. It can also sense minute human breathing or body movements. Both methods can penetrate clothing or air disturbances of a certain thickness and output distance data with centimeter-level accuracy in real time for the processor to adjust the power.

[0043] Specifically, the distance detector 4 can be an ultrasonic sensor, radar detector, or laser detector, utilizing the time-of-flight ranging principle to achieve accurate detection of the target distance. The distance detector 4 is installed on one side of the light wave therapy head 3 and is set at a predetermined installation angle relative to the irradiation direction of the light wave therapy head 3. This installation angle can be set to 15°, thereby shifting the main detection direction of the distance detector 4 towards the center of the treatment area, improving the accuracy of identifying the effective irradiation target.

[0044] Horizontally, the detection range of distance detector 4 covers -15° to 15°, meaning it can effectively detect targets within a 15° fan-shaped area directly in front of it on both sides. Vertically, the detection range of distance detector 4 covers -30° to 30°, meaning it can effectively detect targets within a 30° vertical area directly in front of it on both sides. By limiting the horizontal and vertical detection ranges, distance detector 4 can ensure coverage of the main treatment area while reducing false triggering caused by environmental debris or non-target objects entering the detection area, thereby improving the stability and safety of the system operation.

[0045] In a further preferred embodiment of the present invention, the processor is configured to receive the distance data, and automatically control the light wave therapy head 3 to stop working when the distance data is detected to be less than a minimum threshold, and automatically control the light wave therapy head 3 to resume working when the distance data is detected to be greater than the minimum threshold.

[0046] In this embodiment, the processor continuously receives distance data output from the distance detector 4, which reflects the real-time distance between the light wave therapy head 3 and the irradiated object. The processor has a preset minimum threshold, determined based on the safe irradiation distance of the therapeutic light wave, energy density, and skin tolerance range. When the processor detects that the distance data is less than the minimum threshold, it determines that the irradiation distance is too close and there is a potential safety risk. It then generates a control command to automatically cut off the drive signal of the light wave therapy head 3, causing it to stop working and avoiding excessive local energy or thermal damage caused by excessively close proximity.

[0047] When the processor detects that the distance data becomes greater than the minimum threshold again, it determines that the irradiation distance has been restored to the safe range, and the processor will automatically resume the drive control of the light wave treatment head 3, so that the light wave treatment head 3 resumes output according to the preset working mode. This process does not require manual intervention by the user, and can realize continuous safety monitoring and automatic recovery during the treatment process.

[0048] Through the processor's real-time monitoring of distance data and automatic start-stop control, the physiotherapy lamp can effectively reduce potential safety hazards caused by improper operation or unintentional approach of the user while ensuring the therapeutic effect, and improve the intelligent level and use safety of the device.

[0049] In a further preferred embodiment of the present invention, the physiotherapy lamp further comprises an ambient light sensor and a temperature sensor communicatively connected to the processor, and the processor is configured to: Acquire real-time distance data d(t) collected by the distance detector 4, where t represents time; Acquire ambient light intensity data Lenv collected by the ambient light sensor and target body surface temperature data Tskin collected by the temperature sensor; According to the ambient light intensity data Lenv and the target body surface temperature data Tskin, an adaptive minimum safety threshold Dmin is calculated through a preset dynamic correction model, and the expression of the dynamic correction model is: Dmin=D0 (1+α f(Lenv)+β g(Tskin)) Wherein, D0 is a reference safety distance constant, α is a light intensity correction coefficient, β is a temperature correction coefficient, f(Lenv) is a nonlinear mapping function of ambient light intensity, and g(Tskin) is a monotonically increasing function of body surface temperature; Performing sliding window filtering on the real-time distance data d(t) to obtain a smoothed distance estimation value d^(t); Calculate the change rate v(t)=dd^(t) / dt of the distance estimation value d^(t) over time to characterize the user's movement speed; Control the driving circuit of the light wave treatment head 3 according to the following logic: When d^(t)<Dmin and |v(t)|>vmax, it is determined that there is a sudden approaching risk, and the light wave treatment head 3 is controlled to linearly attenuate from the current power Pcur to zero power within a first preset time; When d^(t)<Dmin and |v(t)|≤vmax, it is determined as a static too-close state, and the light wave treatment head 3 is controlled to stop working immediately; When d^(t)≥Dmin, the light wave therapy head 3 is controlled to return to the preset working power, and the light intensity modulation slope is adjusted according to the positive or negative of the rate of change v(t).

[0050] In this embodiment, the physiotherapy lamp also includes an ambient light sensor (not shown in the figure) and a temperature sensor (not shown in the figure) that are communicatively connected to the processor. The ambient light sensor is used to detect the ambient light intensity around the treatment area, and the temperature sensor is used to detect the surface temperature of the irradiated target. Both sensors establish data communication with the processor to assist in making safety decisions.

[0051] The processor is configured to execute the following intelligent safety control process: First, the processor acquires real-time distance data d(t) collected by distance detector 4, where t represents time; simultaneously, it acquires ambient light intensity data Lenv collected by ambient light sensor and target surface temperature data Tskin collected by temperature sensor. Then, based on the ambient light intensity data Lenv and the target surface temperature data Tskin, the processor calculates the adaptive minimum safety threshold Dmin using a preset dynamic correction model. The expression for this dynamic correction model is: Dmin=D0 (1+ f(Lenv)+β g(Tskin)) Where D0 is the baseline safety distance constant, α is the light intensity correction coefficient, β is the temperature correction coefficient, f(Lenv) is a nonlinear mapping function with respect to ambient light intensity, and g(Tskin) is a monotonically increasing function with respect to skin surface temperature. Using this model, the therapeutic lamp can dynamically adjust the safety distance threshold based on changes in ambient brightness and skin temperature. For example, it can automatically increase the safety distance when ambient light is strong or skin temperature is high to reduce the risk of energy accumulation.

[0052] The processor also performs sliding window filtering on the real-time distance data d(t) to obtain a smoothed distance estimate d^(t) to reduce misjudgments caused by sensor noise. Subsequently, the processor calculates the rate of change of the distance estimate d^(t) over time, v(t) = dd^(t) / dt, which is used to characterize the user's movement speed.

[0053] In terms of control logic, the processor drives the circuit of the light wave therapy head 3 according to the following rules: when d^(t)<Dmin and |v(t)|>vmax, it is determined that there is a sudden approaching risk, and the processor controls the light wave therapy head 3 to linearly decay from the current power Pcur to zero power within a first preset time, so as to realize soft shutdown and avoid sudden change of light intensity or device impact caused by sudden movement; when d^(t)<Dmin and |v(t)|≤vmax, it is determined as a static too-close state, and the processor controls the light wave therapy head 3 to stop working immediately to ensure absolute safety; when d^(t) ≥Dmin, the processor controls the light wave therapy head 3 to restore to the preset working power, and adjusts the light intensity adjustment slope according to the positive or negative of the change rate v(t), so as to realize smooth power transition during the user's approaching or moving away process.

[0054] By introducing ambient light and temperature feedback, dynamic threshold calculation and velocity-based hierarchical control strategy, the physiotherapy lamp can achieve high-precision and high-reliability intelligent safety protection in a variety of usage scenarios, significantly improving user experience and device safety.

[0055] In summary, the physiotherapy lamp provided by the present solution calculates the current irradiation distance between the light wave therapy head and the human body in real time through the distance detector, so that when the irradiation distance changes due to the patient's posture change, the processor can automatically adjust the output power of the light wave therapy head according to the preset safety and treatment curve, ensuring that the treatment effect does not attenuate due to the distance change, realizing the dynamic matching of irradiation dose and distance during the treatment process, and no repeated manual intervention is required.
