[0027] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.
[0028] The terms "first," "second," and the like in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or precedence. It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.
[0029] In related technologies, different wavelengths of therapeutic light are used for different treatment areas or diseases. Regardless of the wavelength of the therapeutic light used, sufficient light energy must be provided to the patient's treated area to ensure treatment efficiency and effectiveness. However, in related technologies, when the therapeutic light emitted by the light source is reflected and emitted outward, some of the reflected light will be directed toward the light source, resulting in a decrease in the energy density of the emitted light, which in turn affects the treatment effect.
[0030] Based on this situation, the embodiment of the present application provides a light distribution component, a light distribution module and a light therapy device. Figures 1 to 5 , the light distribution component provided in the embodiment of the present application is described in detail through specific embodiments and their application scenarios.
[0031] See Figure 1 、 Figure 2 and Figure 3 , the embodiment of the present application discloses a light distribution component, and the disclosed light distribution component can be applied to a phototherapy device, for example, a laser therapy device or an intense pulsed light therapy device. Specifically, the disclosed light distribution component 100 has a accommodating cavity 110 and a light outlet 120 connected to the accommodating cavity 110, and the accommodating cavity 110 is used to accommodate a light source 200. In the embodiment of the present application, when the light source 200 is accommodated in the accommodating cavity 110, the light distribution component 100 constitutes a reflecting wall surface of the light distribution component 100 on the inner wall surface of the accommodating cavity 110, and part of the light emitted by the light source 200 can be directly emitted outward through the light outlet 120, and another part of the light emitted by the light source 200 can also be emitted outward from the light outlet 120 after being reflected by the emitting wall surface.
[0032] See Figure 2 and Figure 3 The reflecting wall surface includes a first reflecting surface 130, a second reflecting surface 140 and a third reflecting surface 150 distributed from the bottom wall of the accommodating cavity 110 to the light outlet 120 and connected in sequence, wherein the first reflecting surface 130 is a circular arc surface convex toward the accommodating cavity 110, the second reflecting surface 140 is a concave circular arc surface, and the third reflecting surface 150 is a curved surface.
[0033] When the light source 200 is accommodated in the accommodating cavity 110, the first reflecting surface 130 reflects the light incident on the first reflecting surface 130 to the third reflecting surface 150; the second reflecting surface 140 reflects the light incident on the second reflecting surface 140 to the third reflecting surface 150 or the light outlet 120. It should be noted that the second reflecting surface 140 has a first area adjacent to the first reflecting surface 130 and a second area adjacent to the third reflecting surface 150. The second reflecting surface 140 reflects the light incident on the first area to the third reflecting surface 150. The second reflecting surface 150 reflects the light incident on the second area to the light outlet 120; the third reflecting surface 150 reflects the light incident on the third reflecting surface 150 to the light outlet 120, and emits it at the light outlet 120. It should be noted that the light incident on the third reflecting surface 150 includes the light emitted by the light source 200 and directly irradiated on the third reflecting surface 150, and also includes the light incident on the third reflecting surface 150 after being reflected by the first reflecting surface 130 and the second reflecting surface 140.
[0034] In some embodiments of the present application, the accommodating cavity 110 can extend through the light distribution component 100 along its axial direction, and the reflective wall surface can be symmetrical about a vertical plane passing through its axis. In this way, the light source 200 can be a cylindrical light source, and the through-arranged accommodating cavity 110 facilitates the installation and fixation of the light source 200. Based on this through-structure of the light distribution component 100, there can be two first reflective surfaces 130, two second reflective surfaces 140, and two third reflective surfaces 150, and the two first reflective surfaces 130 are symmetrical about a vertical plane passing through the axis, the two second reflective surfaces 140 are symmetrical about a vertical plane passing through the axis, and the two third reflective surfaces 150 are symmetrical about a vertical plane passing through the axis. In this way, the entire reflective wall surface has a W-shaped cross-section perpendicular to the axial direction of the light distribution component 100.
[0035] In some embodiments of the present application, the light distribution component 100 may also be a rotating structure, and the light source 200 may be a spherical light source, which is not specifically limited in the present application.
[0036] Based on the above technical solution, the light incident on the first reflection surface 130 is reflected toward the third reflection surface 150, part of the light incident on the second reflection surface 140 is reflected toward the third reflection surface 150, and another part of the light incident on the second reflection surface 140 is reflected toward the light outlet 120. The light reflected by the first reflection surface 130 and the second reflection surface 140 toward the third reflection surface 150, and the light emitted by the light source 200 and directly irradiated on the third reflection surface 150 are reflected by the third reflection surface 150 toward the light outlet 120. In this way, the number of reflections of the light on the reflection wall and the amount of light reflected by the reflection wall toward the light source 200 can be reduced as much as possible, so that as much light as possible is emitted from the light outlet 120, which can effectively reduce the loss of light output and ensure the therapeutic effect of the phototherapy device.
[0037] In an optional embodiment of the present application, the first reflective surface 130 has a first curvature radius R1, and the second reflective surface 140 has a second curvature radius R2, wherein 0.5 mm ≤ R1 ≤ 0.7 mm, and 3 mm ≤ R2 ≤ 5 mm. For example, R1 may be 0.6 mm, R2 may be 4 mm, and the light source 200 may be a cylindrical light source, with the axis of the light source 200 being 7 mm from the vertex of the first reflective surface 130.
[0038] See Figure 3 and Figure 4 The embodiment of the present application also discloses a light distribution module, which includes a light source 200 and the aforementioned light distribution component 100. The light source 200 is arranged in the accommodating cavity 110 of the light distribution component 100. For example, in the light distribution module disclosed in the embodiment of the present application, the light source 200 can be a cylindrical xenon lamp, and the accommodating cavity 110 passes through the light distribution component 100 along the axial direction of the light distribution component 100. The axial direction of the cylindrical xenon lamp coincides with or is parallel to the axial direction of the light distribution component 100, so as to facilitate the installation of the light source 200 in the light distribution component 100.
[0039] In the examples of this application, please continue to refer to Figure 3 、 Figure 4 and Figure 5 The light distribution module also includes a support 300. Two supports 300 are relatively arranged in the accommodating cavity 110 to support the two ends of the light source 200. That is, the two ends of the light source 200 are supported on the two supports 300 to form a fixation in the accommodating cavity 110. On the one hand, the supports 300 provide stable support for the light source 200, which can prevent the light source 200 from sliding or shifting during use. On the other hand, this installation method ensures that the axial direction of the light source is consistent with the axial direction of the light distribution component, avoiding the problem of uneven light distribution caused by the offset of the light source, thereby ensuring the therapeutic effect of the phototherapy device.
[0040] In some embodiments of this application, see Figure 1 and Figure 4The light distribution component 100 has a first positioning surface 160, which is perpendicular to the axial direction of the light distribution component 100. It should be noted that in the embodiment of the present application, there may be two first positioning surfaces 160. In the axial direction of the light distribution component 100, the two supports 300 are respectively positioned and matched with the two first positioning surfaces 160, thereby achieving the positioning of the supports 300 in the axial direction of the light distribution component 100; it is understandable that the two first positioning surfaces 160 respectively positioned and matched with the two supports 300 can be arranged facing each other, facing each other, or arranged in the same direction, and the embodiment of the present application does not impose any specific restrictions on this.
[0041] In some embodiments of this application, please continue to refer to Figure 1 and Figure 4 The light distribution component 100 has a second positioning surface 170. Along the inward direction of the opening of the accommodating cavity 110, the support 300 is limitedly engaged with the second positioning surface 170, thereby positioning the support 300 in the direction of the opening of the light distribution component 100. The provision of the first positioning surface 160 and the second positioning surface 170 improves the ease of assembly of the support 300 and the light distribution component 100. After the support 300 is pre-positioned against the first positioning surface 160 and the second positioning surface 170, the support 300 and the light distribution component 100 can then be connected and fixed by gluing.
[0042] In a further technical solution, the light distribution module may further include a cladding layer 400, which is disposed outside the light source 200 and is translucent. The cladding layer 400 allows light emitted by the light source 200 to pass through the cladding layer 400 and illuminate the reflective wall surface. For example, the cladding layer 400 may be a glass layer with good translucency to ensure that the light emitted by the light source 200 passes through the cladding layer 400 and exits the reflective wall surface.
[0043] A gap is provided between the cladding layer 400 and the light source 200 to form a hollow interlayer. This hollow interlayer is used to accommodate a heat-conducting medium. When the heat-conducting medium is filled in the hollow interlayer, the heat-conducting medium directly contacts the light source 200 for heat exchange, thereby providing heat dissipation for the light source 200. In a preferred embodiment, the hollow interlayer has a medium inlet and a medium outlet, through which the heat-conducting medium can circulate to remove absorbed heat, thereby ensuring continuous heat dissipation for the light source 200. For example, the heat-conducting medium can be water, including but not limited to purified water, distilled water, and deionized water.
[0044] In a further technical solution, the light distribution module may further include a filter (not shown in the figure), which is arranged on the light distribution component 100 and at the light outlet 120 of the light distribution component 100. The filter can be attached to the aforementioned second positioning surface 170. In this way, on the one hand, the filter can effectively filter out unnecessary stray light, thereby improving the stray light emitted by the light distribution module. On the other hand, the filter can also provide a certain degree of protection for the light source 200.
[0045] An embodiment of the present application also discloses a light therapy device, which includes the aforementioned light distribution module.
[0046] It should be noted that, in this article, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the statement "comprises a ..." does not exclude the presence of other identical elements in the process, method, article or device comprising the element. In addition, it should be noted that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in the opposite order according to the functions involved. For example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.
[0047] The above is only a specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with this technical field can easily think of changes or replacements within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
