Description

Technical Field

[0001] The utility model relates to an ultraviolet light therapy system, in particular to an array type ultraviolet LED irradiation system. Background Art

[0002] With the development of medical technology, ultraviolet light therapy is increasingly used in the treatment of skin diseases. However, existing ultraviolet light therapy equipment often cannot avoid damaging healthy skin during the irradiation process. Therefore, how to achieve precise ultraviolet light irradiation has become an urgent problem to be solved.

[0003] A digital micromirror device (DMD) is a microelectromechanical system (MEMS) device developed by Texas Instruments and widely used in projection display and photolithography technologies. A DMD consists of millions of tiny, independently tiltable mirrors that can rapidly switch between +12 and -12 degrees, enabling precise control of light. The core technology of a DMD lies in its micromirror array, each of which can independently control its tilt angle to reflect or deflect light.

[0004] Existing ultraviolet phototherapy equipment usually uses a fixed light source and a simple optical path system, which makes it difficult to achieve accurate irradiation of complex lesion areas. Especially during the treatment process, the scattering and reflection of light can easily lead to misirradiation of healthy skin, causing unnecessary damage. Chinese invention patent application 202311546959.0 proposes a system that uses a servo motor to control optical lenses to achieve precise irradiation, but there are still problems with the system being complex, large in size, and noisy. DMD-based ultraviolet phototherapy equipment can achieve precise control of the ultraviolet light beam by precisely controlling the angle of the micromirror array, thereby effectively avoiding damage to healthy skin and improving the safety and effectiveness of treatment.

[0005] Therefore, the present invention combines DMD technology to provide an array-type ultraviolet LED irradiation system to solve the above-mentioned problems in the prior art, achieve precise irradiation of the lesion area, improve the treatment effect, and reduce damage to healthy skin. Utility Model Content

[0006] To achieve the above-mentioned objectives, the present invention provides an array-type ultraviolet LED irradiation system, comprising: an LED ultraviolet light source for emitting ultraviolet light; an ultraviolet beam control module for controlling and adjusting the optical path of the ultraviolet light from the LED ultraviolet light source so that its area and angle match the micromirror array of the DMD; a DMD for receiving the ultraviolet light from the ultraviolet beam control module and selectively reflecting the ultraviolet light according to a control signal; a projection lens module for projecting the ultraviolet light beam reflected from the DMD onto a target area; a camera for capturing an image of the target area; and a computer control module for receiving the image from the camera, identifying and labeling the treatment area, and generating a control signal to control the DMD so that the ultraviolet light beam is accurately projected onto the treatment area.

[0007] Furthermore, the ultraviolet beam control module includes a lens group and a reflector. The ultraviolet light from the LED ultraviolet light source passes through the ultraviolet beam lens group and is reflected onto the micromirror array of the DMD through the reflector.

[0008] Furthermore, the reflector is a plane reflector or a concave reflector with refractive power.

[0009] Furthermore, the lens group includes one or more of a biconvex lens, a plano-convex lens, and a concave-convex lens.

[0010] Furthermore, the computer control module automatically identifies and labels the treatment area based on the image of the target area, and generates a control signal to control the DMD so that the shape and size of the ultraviolet light beam match the treatment area.

[0011] Furthermore, the computer control module monitors the changes of the target area in real time and dynamically adjusts the control signal of the DMD to compensate for the changes of the target area.

[0012] Furthermore, the arrayed ultraviolet LED irradiation system further includes: a display for displaying an image of the target area and an identification of the treatment area; and a user interface for allowing a user to select treatment parameters.

[0013] The array-type UV LED irradiation system provided by this utility model realizes precise control and adjustment of the UV beam by adopting DMD (digital modulator) technology and computer control module, achieving the following technical effects:

[0014] Precise irradiation: By controlling the UV beam through the DMD micromirror array, the UV light can be precisely projected onto the lesion area, avoiding accidental irradiation of healthy skin, thereby reducing side effects and adverse reactions during treatment.

[0015] Efficient treatment: The computer control module automatically identifies and marks the treatment area based on the image of the lesion area captured by the camera, and accurately controls the movement of the DMD micromirror array, so that the ultraviolet beam can focus and effectively irradiate the lesion area, improving treatment efficiency and effectiveness.

[0016] Intelligent operation: The camera monitors the image of the lesion area in real time and transmits the image to the computer control module for processing and analysis, realizing intelligent identification and automatic control of the treatment area, simplifying the operation steps and improving the intelligence level of the equipment.

[0017] Improved safety: By precisely controlling the projection range of the UV beam, the damage of UV light to healthy skin can be effectively avoided, which improves the safety of UV therapy and protects the patient's skin health.

[0018] Strong adaptability: The array-type ultraviolet LED irradiation system of this utility model can adapt to different treatment needs through flexible adjustment of the DMD micromirror array according to the size and shape of different lesion areas. It has strong adaptability and broad application prospects.

[0019] Real-time feedback and adjustment: The system can monitor and provide feedback on changes in the lesion area in real time during treatment, and dynamically adjust the control parameters of the DMD micromirror array as needed to ensure continuous optimization of the treatment process.

[0020] In summary, the present invention provides an efficient, safe and intelligent ultraviolet phototherapy solution by combining DMD technology and computer control technology, effectively solving the defects and shortcomings of the existing technology, achieving precise irradiation of the lesion area, and improving the therapeutic effect and safety of ultraviolet phototherapy.
