Specifically, the light source disposed in the phototherapy device can emit light, and the light is irradiated to the phototherapy area, such as human skin, to achieve effects such as scarring, wound healing, and sleep improvement.
为了提高用户体验，目前的光疗设备的厚度越来越薄，由此导致在使用光疗设备时，光疗设备的光源与光疗区域例如皮肤之间的距离较近，光源射出的光线到达光疗区域的光路变短，因此难以形成均匀的出光面，容易在光疗区域上形成汇聚的刺眼光斑。光疗区域中汇聚光斑照射下的部分所吸收的光能过多，未处于汇聚光斑照射下的部分所吸收的光能过少。In order to improve the user experience, the thickness of current phototherapy devices is getting thinner and thinner, thereby causing the distance between the light source of the phototherapy device and the phototherapy region, such as the skin, when the phototherapy device is used, and the light emitted by the light source reaches the light path of the phototherapy region. It becomes shorter, so it is difficult to form a uniform light-emitting surface, and it is easy to form a concentrated glare spot on the phototherapy area. The portion of the phototherapy region where the concentrated spot is irradiated absorbs too much light energy, and the portion that is not exposed to the concentrated spot absorbs too little light energy.

具体实施方式detailed description
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚地描述，显然，所描述的实施例是本发明一 部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。The technical solutions in the embodiments of the present invention will be clearly described in conjunction with the drawings in the embodiments of the present invention. Invention one Some embodiments, but not all of the embodiments.

目前的光疗设备的厚度越来越薄，使得光疗设备中光源所射出光线的混光高度受限，难以在光疗区域例如皮肤表面形成均匀的出光面，从而容易在皮肤上形成汇聚的刺眼光斑。尤其是当光疗设备以LED阵列作为光源时尤甚。At present, the thickness of the phototherapy device is thinner and thinner, so that the light mixing height of the light emitted by the light source in the phototherapy device is limited, and it is difficult to form a uniform light-emitting surface in the phototherapy region such as the skin surface, thereby easily forming a concentrated glare spot on the skin. This is especially true when phototherapy devices use LED arrays as light sources.
汇聚光斑照射下的皮肤所吸收的光能过多，而未处于汇聚光斑照射下的皮肤所吸收的光能过少。刺眼的光斑会对进行光疗的患者带来困扰，而且有可能灼伤皮肤，使得原本用于治疗的光线反而带来伤害，如在皮肤上照射形成点阵的斑纹。可见，不均匀的出光面降低了用户体验。The skin absorbed by the concentrated spot absorbs too much light energy, while the skin that is not exposed to the concentrated spot absorbs too little light energy. A glare of light can cause problems for patients undergoing phototherapy, and it can burn the skin, causing damage to the light that was originally used for treatment, such as the formation of a dot pattern on the skin. It can be seen that the uneven illuminating surface reduces the user experience.
为此，本发明实施例提供了一种光疗设备，该光疗设备包括电路基板、光源和光线可穿透的扩散模块，电路基板的主面上设置了光源，电路基板用于为光源提供工作电源，使得光源可以向远离所述主面的方向射出光线。扩散模块设置在所述主面所朝向的一侧，由此，从光源射出的光线在到达光疗区域之前会先通过所述扩散模块，扩散模块为光线可穿透的材质，该扩散模块可以对穿过自身的光线进行扩散，使得当所述光源射出的光线从所述扩散模块射出时的出射角大于所述光源射出的光线射入所述扩散模块的入射角。通过扩散模块对光源射出光线的扩散，使得光源射出光线的出光面更为均匀，将较不容易在光疗区域形成汇聚的光斑，提高了用户体验。To this end, an embodiment of the present invention provides a phototherapy apparatus including a circuit substrate, a light source, and a light diffusing diffusion module. The main surface of the circuit substrate is provided with a light source, and the circuit substrate is used to provide a working power source for the light source. So that the light source can emit light in a direction away from the main surface. The diffusion module is disposed on a side of the main surface, so that the light emitted from the light source passes through the diffusion module before reaching the phototherapy region, and the diffusion module is a light-transmissible material, and the diffusion module can be The light passing through itself diffuses such that an exit angle when the light emitted by the light source exits the diffusion module is greater than an incident angle of the light emitted by the light source into the diffusion module. The diffusion of the light emitted by the light source by the diffusion module makes the light emitting surface of the light source more uniform, and it is less likely to form a concentrated spot in the phototherapy area, thereby improving the user experience.
图1为本发明实施例提供的一种光疗设备的装置结构图，该光疗设备包括电路基板10、光源20和光线可穿透的扩散模块40。需要说明的是，为了便于清楚展示光疗设备中的各个组成部分，图1中扩散模块40与电路基板10之间的距离较远，图1所示的虚线框是为了便于明确示出光源10，其中全部黑色圆点可以组成光源10。图1中所示的虚线箭头200可以用于示出光源10中一个发光点所射出光线的主要射出方向。FIG. 1 is a structural diagram of a device for a phototherapy apparatus according to an embodiment of the present invention. The phototherapy apparatus includes a circuit substrate 10, a light source 20, and a light diffusing diffusion module 40. It should be noted that, in order to facilitate the clear display of various components in the phototherapy apparatus, the distance between the diffusion module 40 and the circuit substrate 10 in FIG. 1 is relatively long, and the dotted line frame shown in FIG. 1 is for the purpose of clearly showing the light source 10, All of the black dots can constitute the light source 10. The dashed arrow 200 shown in FIG. 1 can be used to show the main exit direction of the light emitted by one of the light-emitting points in the light source 10.
电路基板10的主面11上设置了光源20，电路基板10用于为光源20提供工作电源。光源20用于向远离主面11的方向射出光线。A light source 20 is disposed on the main surface 11 of the circuit substrate 10, and the circuit substrate 10 is used to supply a working power source to the light source 20. The light source 20 is for emitting light in a direction away from the main surface 11.
举例说明，光源20可以包括一个子光源21(或者称为发光模块)，也可以包括多个子光源21，多个子光源21也可以形成阵列的结构。其中，子光源21可以是LED模块。LED模块可发出的光线的光谱半宽较窄、波长几近覆盖全可见光及红外波段、与光谱且易于调节控制的优点，采用经医学研究证明有明显疗效的特殊LED光谱或光谱组合，并精准调节其出光强度、照射时间等参数，以达到对特定疾病的针对性治疗效果，故利用LED模块可 以使用特定的有效光谱组合实现光疗的作用。同时，利用LED模块安全冷光、结构小巧、易于灵活拼凑的优点，将多个单一的LED模块紧凑排布为LED阵列。在本发明实施例中，光源20为光疗设备中用于射出具有光疗效果的光线的光源。For example, the light source 20 may include one sub-light source 21 (also referred to as a light emitting module), and may also include a plurality of sub-light sources 21, and the plurality of sub-light sources 21 may also form an array structure. The sub-light source 21 can be an LED module. The LED module emits light with a narrow spectrum half-width, a near-wavelength coverage of all visible light and infrared bands, and a spectral and easy-to-adjust control. A special LED spectrum or spectral combination that has been proven to be effective by medical research is accurate. Adjusting the parameters such as light intensity and irradiation time to achieve targeted treatment effects for specific diseases, so LED modules can be used. The effect of phototherapy is achieved using a specific combination of effective spectra. At the same time, the LED module is compact and arranged as an LED array by utilizing the advantages of safe cold light, compact structure and easy flexibility. In the embodiment of the present invention, the light source 20 is a light source for emitting light having a phototherapy effect in the phototherapy apparatus.
在光源20包括至少一个LED模块的情况下，LED模块可以以一定的阵列形式排布，阵列形式包含但不限于矩阵形式与同心圆环形式，并通过焊接等方式固接在柔性的电路基板10的主面11之上。为防止LED模块的磨损，LED模块外还可以罩设有封装透镜。在图1中所示的是一种可选的3×3的LED模块阵列形成的光源20。In the case that the light source 20 includes at least one LED module, the LED modules may be arranged in a certain array form, including but not limited to a matrix form and a concentric annular form, and are fixed to the flexible circuit substrate 10 by soldering or the like. Above the main face 11. In order to prevent the wear of the LED module, the LED module can also be covered with a package lens. Shown in Figure 1 is an alternative light source 20 formed by a 3 x 3 array of LED modules.
设置有光源20的电路基板10可以是具有固定形状的硬性结构，也可以是可改变形状的柔性结构。柔性的电路基板10通过一定程度的弯曲，可以实现较大面积的软体亲肤光疗设备。也就是说，主面11可以是一个平面，也可以是一个曲面，也可以是其他可能的形状。The circuit substrate 10 provided with the light source 20 may be a rigid structure having a fixed shape or a flexible structure that can be changed in shape. The flexible circuit substrate 10 can realize a large-area soft skin phototherapy device by a certain degree of bending. That is to say, the main surface 11 can be a flat surface, a curved surface, or other possible shapes.
本发明实施例提供的光疗设备可广泛应用于便携式、可穿戴式的光学治疗。该光疗设备可以是可穿戴式的，以达到更便利的光疗条件。The phototherapy apparatus provided by the embodiments of the present invention can be widely applied to portable, wearable optical therapy. The phototherapy device can be wearable to achieve more convenient phototherapy conditions.
光源20射出的光线会照射到光疗区域上，由于目前的光疗设备的厚度越来越薄，使得光疗设备中光源所射出光线的混光高度受限，难以在光疗区域例如皮肤表面形成均匀的出光面，当光疗设备以LED阵列作为光源时尤甚，可能会导致在皮肤上形成汇聚的光斑。不均匀的出光面会降低用户体验。The light emitted by the light source 20 is irradiated onto the phototherapy area. Since the thickness of the current phototherapy apparatus is thinner and thinner, the light mixing height of the light emitted by the light source in the phototherapy apparatus is limited, and it is difficult to form a uniform light output in the phototherapy area such as the skin surface. In particular, when phototherapy devices use LED arrays as light sources, they may cause concentrated spots on the skin. Uneven illuminating surfaces can reduce the user experience.
为此，本发明实施例中提供了一种光线可穿透的扩散模块，通过将该扩散模块40设置在上述光疗设备中，以改善光疗设备出光面的均匀性。To this end, in the embodiment of the present invention, a light-transmissive diffusion module is provided, and the diffusion module 40 is disposed in the phototherapy device to improve the uniformity of the light-emitting surface of the phototherapy device.
该光疗设备所包括的光线可穿透的扩散模块40可以设置在主面11所朝向的一侧，例如图2所示，扩散模块40用于对穿过扩散模块40的光线进行扩散，使得当光源20所射出光线从扩散模块40射出时的出射角大于光源20所射出光线射入扩散模块40时的入射角。The light-transmissive diffusion module 40 included in the phototherapy device may be disposed on a side of the main surface 11 facing, for example, as shown in FIG. 2, the diffusion module 40 is configured to diffuse light passing through the diffusion module 40, so that when The exit angle when the light emitted from the light source 20 is emitted from the diffusion module 40 is larger than the incident angle when the light emitted from the light source 20 is incident on the diffusion module 40.
举例说明，扩散模块40的体材料可以采用高透过低吸收材质，包含但不限于PMMA(聚甲基丙烯酸甲酯)材料，以减少对在其中多次穿过的光线的吸收，如此则可有效提高光能利用率。从光源射出的光线在到达光疗区域之前会先通过所述扩散模块，扩散模块为光线可穿透的材质，该扩散模块可以对穿过自身的光线进行扩散，使得当所述光源射出的光线从所述扩散模块射出时的出射角大于所述光源射出的光线射入所述扩散模块的入射角。通过扩散模块对光源射出光线的扩散，使得光源射出光线的出光面更为均匀，将较不容易在光疗区域形成汇聚的光斑，提高了用户体验。For example, the bulk material of the diffusion module 40 can be made of a high transmission low absorption material, including but not limited to PMMA (polymethyl methacrylate) material, to reduce the absorption of light passing through it many times, so Effectively improve the utilization of light energy. The light emitted from the light source passes through the diffusion module before reaching the phototherapy region, and the diffusion module is a light-transmissive material, and the diffusion module can diffuse light passing through itself, so that the light emitted from the light source is The exit angle when the diffusion module is emitted is greater than the incident angle of the light emitted by the light source into the diffusion module. The diffusion of the light emitted by the light source by the diffusion module makes the light emitting surface of the light source more uniform, and it is less likely to form a concentrated spot in the phototherapy area, thereby improving the user experience.
接下来说明如何将扩散模块40设置在光疗设备中。本发明实施例提供了多种在光疗设 备中设置扩散模块40的方式。Next, how to set the diffusion module 40 in the phototherapy apparatus will be explained. Embodiments of the present invention provide various types of phototherapy The manner in which the diffusion module 40 is provided is provided.
可以将扩散模块40朝向光源20的一面固定贴合在主面11上。具体的固定方式可以如图3a或者图3b所示。The diffusion module 40 can be fixedly attached to the main surface 11 on one side of the light source 20. The specific fixing method can be as shown in Fig. 3a or Fig. 3b.
也可以将扩散模块40通过固定装置50与电路基板10固定连接。具体的固定方式可以如图3c所示。The diffusion module 40 can also be fixedly connected to the circuit substrate 10 by the fixing device 50. The specific fixing method can be as shown in Fig. 3c.
为了进一步提高扩散模块40对光线的扩散效果，可以在扩散模块40上设置凸起结构41。可以通过网点印刷或激光打点法等方式在扩散模块40上形成凸起结构41，凸起结构41的形状可以是金字塔形，也可以是其他形状。各个凸起结构41的尺寸可以相同，也可以不同。本发明并不限定扩散模块40上所设置凸起结构41的数量。凸起结构41可以设置在扩散模块40表面中处于光源20射出光线的光路上的部分，可以将凸起结构41均匀的设置在上述部分，也可以不均匀的设置在上述部分。由于凸起部分41设置在光源20所射出光线的光路上，故可以通过凸起结构41对穿过扩散模块40的光线进行扩散。进一步提高对光源20所射出光线的扩散，从而提高光源20所射出光线在光路区域上出光面的均匀性。凸起结构41的扩散效果可以参见图4，图4所示的是凸起结构41设置在扩散模块40背向光源20一面的表面上的光路扩散情况的示意。可见，一条从光源20射出的光线(光路可以参见图4中的虚线箭头所示)射入扩散模块40的入射角α明显小于这条光线离开一个凸起结构41时的出射角β，从而这个凸起结构通过扩散作用增大了这条光线的射出角度，降低了大量光线汇聚在一个区域的可能。针对扩散模块40的光路分析也可以参见图4，不再赘述。In order to further improve the diffusion effect of the diffusion module 40 on light, a convex structure 41 may be disposed on the diffusion module 40. The protrusion structure 41 may be formed on the diffusion module 40 by dot printing or laser dot method, and the shape of the protrusion structure 41 may be a pyramid shape or other shapes. The size of each of the raised structures 41 may be the same or different. The present invention does not limit the number of raised structures 41 provided on the diffusion module 40. The convex structure 41 may be disposed on a portion of the surface of the diffusion module 40 on the optical path on which the light source 20 emits light, and the convex structure 41 may be uniformly disposed in the above portion or may be unevenly disposed on the portion. Since the convex portion 41 is disposed on the optical path of the light emitted from the light source 20, the light passing through the diffusion module 40 can be diffused by the convex structure 41. Further, the diffusion of the light emitted from the light source 20 is further increased, thereby improving the uniformity of the light exiting surface of the light source 20 on the light path region. The diffusion effect of the raised structure 41 can be seen in FIG. 4. FIG. 4 is a schematic illustration of the diffusion of the optical path provided by the raised structure 41 on the surface of the diffusion module 40 facing away from the side of the light source 20. It can be seen that an incident angle α of the light emitted from the light source 20 (the optical path can be shown by the dotted arrow in FIG. 4) entering the diffusion module 40 is significantly smaller than the exit angle β when the light leaves the convex structure 41, and thus The convex structure increases the angle of incidence of the light by diffusion, reducing the possibility of a large amount of light concentrating in one area. The optical path analysis for the diffusion module 40 can also be seen in FIG. 4 and will not be described again.
接下来进一步说明凸起结构41在扩散模块40上的设置位置。本发明实施例提供了多种设置凸起结构41的方式，其中包括至少三种设置方式。Next, the position where the convex structure 41 is disposed on the diffusion module 40 will be further explained. Embodiments of the present invention provide various ways of providing the raised structure 41, including at least three arrangements.
第一种设置方式可以将凸起结构41设置在扩散模块40朝向光源20一面的表面上。针对该第一种设置方式，可以包括多个不同的设置形式。The first arrangement can provide the raised structure 41 on the surface of the diffusion module 40 that faces one side of the light source 20. For this first setting, a plurality of different setting forms can be included.
例如可以将凸起结构41设置在光源20光路方向的正前方，具体可以如图5a所示。For example, the convex structure 41 can be disposed directly in front of the optical path of the light source 20, as shown in FIG. 5a.
例如还可以将凸起结构41罩设在光源20的***，具体可以如图5b所示。For example, the protruding structure 41 can also be disposed on the periphery of the light source 20, as shown in FIG. 5b.
第二种设置方式可以将凸起结构41设置在扩散模块40背向光源20一面的表面上，具体可以如图5c所示。In the second arrangement, the protruding structure 41 can be disposed on the surface of the diffusion module 40 facing away from the light source 20, as shown in FIG. 5c.
第三种设置方式可以将凸起结构41设置在扩散模块40背向光源20一面的表面上和朝向光源20的一面上，具体可以如图5d或图5e所示。 In a third arrangement, the protruding structure 41 can be disposed on the surface of the diffusion module 40 facing away from the side of the light source 20 and on the side facing the light source 20, as shown in FIG. 5d or 5e.
在上述图5a至图5e中，扩散模块40还可以通过连接装置50与电路基板10进行固结。In the above-described FIGS. 5a to 5e, the diffusion module 40 can also be consolidated with the circuit substrate 10 by the connection device 50.
