[0002] Phototherapy is a medical method that uses the energy of light to treat diseases or improve physical conditions. It has a wide range of applications in the medical field, such as using blue light to treat acne and using red light to promote repair.

[0003] Existing phototherapy equipment that uses natural light mainly uses a prism to directly refract the light and then collects the colored light through a filter for use. This type of equipment has a simple structure, cannot adjust the light intensity, and is highly dependent on the environment, resulting in unstable treatment effects. Summary of the invention

A plurality of light-transmitting ports are arranged on the beam splitter, and the light-transmitting ports are used to receive the dispersed light. The light-transmitting ports are provided with color films, and the color films correspond to the color of the dispersed light; the light therapy component is detachably connected to the beam splitter, and the light therapy component is arranged one-to-one with the light-transmitting ports. The light therapy component is connected to the corresponding light-transmitting ports, and the light therapy component is used to output colored light to the user.

[0007] At least the following beneficial effects are achieved:

[0008] The concave mirror and the reflector form a double reflection focusing system, which concentrates natural light to the light transmission hole through two reflections, so that the initial light intensity is increased by 2-3 times, reducing the dependence on external high-power light sources, and can also collect a certain amount of light in rainy weather. By arranging the convex lens that slides vertically in the box, the physical adjustment of the focusing degree of the light beam is achieved. Sliding the convex lens can change the vertical distance between it and the light transmission hole, thereby adjusting the convergence or divergence state of the incident light beam, and can also adjust the distance from the light converged by the convex lens to the prism group. When the convex lens moves up and approaches the light transmission hole, the focused light shape The convex lens is moved downward away from the light-transmitting hole to form a high-intensity narrow light beam, and the light beam is diverged into the space of the box to reduce the energy density. The sliding of the convex lens can realize linear adjustment of light intensity to adapt to different treatment needs. The box effectively isolates light interference from the external environment to ensure the purity of the spectrum after dispersion. The prism group can compensate for the dispersion shift caused by ambient temperature fluctuations through multi-prism cascade refraction, thereby ensuring the stability of the output spectrum and facilitating the light collection by the beam splitter. The color film at the light-transmitting port of the beam splitter filters stray light for a second time, so that the final output color light wavelength deviation is controlled within ±2nm, thereby ensuring that the phototherapy component outputs ideal color light.

[0009] According to some embodiments of the present invention, the prism group includes a first prism and a second prism, the first prism is hinged in the box, the first prism is arranged below the convex lens, and the first prism is used to refract the light emitted from the convex lens; the second prism is vertically slidably connected to the box, the second prism is arranged below the first prism, and the second prism is used to refract the light emitted from the first prism; the first prism and the second prism cooperate to refract the light to form dispersion, the first prism performs a primary dispersion on the converged light output by the convex lens, and decomposes the white light into a wide spectrum; the second prism performs a secondary refracting on the dispersed light of the first prism, further expanding the separation spacing of light of different wavelengths, and facilitating the subsequent collection of colored light by the beam splitter, the hinged structure of the first prism facilitates adjustment of its inclination angle, and can directionally enhance the refractive index difference in a specific band to achieve preferential separation of the target wavelength, the sliding adjustment of the second prism can control the spacing between the two prisms, and achieve compression or expansion of the dispersion range. When the spacing is reduced, the light beams overlap to enhance the dispersion density, and when the spacing is increased, the dispersion is more uniform, which is convenient for adjustment according to needs.

[0010] According to some embodiments of the present invention, both the first prism and the second prism are made of flint glass, and the refractive index of flint glass is more suitable for light dispersion.

[0011] According to some embodiments of the present invention, a slider is provided in the box, and the slider is provided below the first prism. There are two sliders, and the two sliders are respectively slidably connected to the left inner wall and the right inner wall of the box. The left end of the second prism is hinged on the corresponding slider, and the slider is used to drive the second prism to slide vertically.

[0012] According to some embodiments of the present invention, the light therapy component includes a light guide and a light therapy cover, the light guide is detachably connected to the light splitter plate, the light guide is arranged in a one-to-one correspondence with the light transparent port, and one end of the light guide is connected to the corresponding light transparent port; a plurality of light therapy covers are provided, and the light therapy covers are arranged in a one-to-one correspondence with the light guide, and the light therapy cover is connected to the other end of the light guide, and the light therapy cover is used to output colored light to a user.

The cover wall space is connected to a fan, and the fan is used to dissipate the heat in the cover wall space. The semiconductor refrigeration plate can adjust the temperature of the output light, so that the output colored light can be easily adapted to the treatment needs.

[0014] According to some embodiments of the present invention, the semiconductor refrigeration sheet is a flexible semiconductor refrigeration belt, which is arranged in a ring shape on the wall of the phototherapy cover. The ring distribution can make the temperature evenly distributed, which is convenient for adjusting the temperature during phototherapy.

[0015] According to some embodiments of the present invention, the fan is connected to the hood wall space via an air suction pipe.

[0045] Reference Figures 1 to 8The present invention discloses a decentralized phototherapy device based on natural light, including a box 100, a focusing component 200, a prism group 300, a beam splitter 400 and a phototherapy component 500, and the lower end of the box 100 is opened.

[0046] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 The focusing assembly 200 includes a concave mirror 210, a bracket 220, a reflector 230 and a convex lens 240. The bracket 220 is arranged on the housing 100. The concave mirror 210 is arranged in a space defined by the bracket 220. The reflector 230 is arranged on the bracket 220. The reflective surface of the reflector 230 is arranged toward the concave mirror 210. The concave mirror 210 is configured to reflect light to the reflector 230. A light-transmitting hole 211 is arranged at the bottom of the concave mirror 210. The light-transmitting hole 211 is connected to the inner cavity of the housing 100. The reflector 230 is used to reflect light into the light-transmitting hole 211. The convex lens 240 is connected to the housing 100 along a vertical sliding direction. The convex lens 240 is used to receive light input from the light-transmitting hole 211. It can be understood that the concave mirror 210 is arranged in a hemispherical shape, and a reflective patch or a reflective layer is arranged inside the hemisphere. It can be understood that the bracket 220 includes two parts. The first part is a base body, which is arranged at the upper end of the box body 100, and then the concave mirror 210 is arranged on the base body. The second part of the bracket 220 is a support body. The purpose of the support body is to support the reflector 230. At the same time, the support body can also cooperate with the base body to fix the concave mirror 210 on the bracket 220.

[0047] Reference Figure 3 , Figure 5 and Figure 6 The prism group 300 is arranged in the box body 100, and the prism group 300 is arranged below the convex lens 240. The prism group 300 is used to refract the light output by the convex lens 240 to form dispersion; the beam splitter 400 is detachably plugged into the lower end of the box body 100, and the beam splitter 400 is arranged below the prism group 300. A plurality of light-transmitting ports 410 are arranged on the beam splitter 400. The light-transmitting ports 410 are used to receive the dispersed light, and a color film 411 is arranged on the light-transmitting port 410. The color film 411 corresponds to the color of the dispersed light; the light therapy component 500 is detachably connected to the beam splitter 400, and the light therapy component 500 is arranged one-to-one with the light-transmitting port 410. The light therapy component 500 is connected to the corresponding light-transmitting port 410, and the light therapy component 500 is used to output colored light to the user.

[0048] It should be understood that the concave mirror 210 and the reflector 230 form a double-reflection focusing system, which concentrates natural light to the light-transmitting hole 211 through two reflections, so that the initial light intensity is increased by 2-3 times, reducing the dependence on external high-power light sources, and can also collect a certain amount of light in rainy weather. By arranging a vertically sliding convex lens 240 in the box body 100, physical adjustment of the focusing degree of the light beam is achieved. The sliding convex lens 240 can change its vertical distance from the light-transmitting hole 211, thereby adjusting the convergence or divergence state of the incident light beam, and can also adjust the distance from the light converged by the convex lens 240 to the prism group 300. When the convex lens 240 moves up and approaches the light-transmitting hole 211, the focused light forms a high-intensity narrow light beam. When the convex lens 240 moves down and away from the light-transmitting hole 211, the light beam diverges into the space of the box 100 to reduce the energy density. The sliding of the convex lens 240 can realize linear adjustment of the light intensity to adapt to different treatment needs. The box 100 effectively isolates the light interference from the external environment to ensure the spectral purity after dispersion. The prism group 300 can compensate for the dispersion shift caused by ambient temperature fluctuations through multi-prism cascade refraction, ensure the output spectrum stability, and facilitate the light splitter 400 to collect light. The color film 411 at the light-transmitting port 410 of the light splitter 400 filters the stray light for the second time to ensure that the phototherapy component 500 outputs ideal color light.

[0049] Reference Figure 3 , Figure 5 and Figure 6 The prism group 300 includes a first prism 310 and a second prism 320. The first prism 310 is hinged in the housing 100 and is disposed below the convex lens 240. The first prism 310 is used to refract the light emitted from the convex lens 240. The second prism 320 is vertically slidably connected in the housing 100 and is disposed below the first prism 310. The second prism 320 is used to refract the light emitted from the first prism 310. The first prism 310 and the second prism 320 cooperate to refract the light to form dispersion. The first prism 310 has a high degree of chromatic aberration on the output of the convex lens 240. The light is focused for the first dispersion, decomposing the white light into a wide spectrum; the second prism 320 performs secondary refraction on the dispersed light of the first prism 310, further expanding the separation spacing of light of different wavelengths, and facilitating the subsequent light splitter 400 to collect colored light. The hinged structure of the first prism 310 facilitates the adjustment of its tilt angle, and can enhance the refractive index difference of a specific band in a direction to achieve the preferential separation of the target wavelength. The sliding adjustment of the second prism 320 can control the spacing between the two prisms, and achieve the compression or expansion of the dispersion range. When the spacing is reduced, the light beam overlaps to enhance the dispersion density, and when the spacing is increased, the dispersion is more uniform, which is convenient for adjustment as needed. It can be understood that the inner cavity of the box 100 is arranged in a circular shape, and the first prism 310 and the second prism 320 are both hinged on the disk, and the first prism 310 is fixed to the inner cavity of the box 100 with its disk, and the second prism 320 is connected to the corresponding slider 110 with its disk.

[0050] In some embodiments, the first prism 310 and the second prism 320 are both made of flint glass, and the refractive index of flint glass is more suitable for light dispersion.

[0051] Reference Figure 5 and Figure 6 A slider 110 is provided in the box 100, and the slider 110 is provided below the first prism 310. There are two sliders 110, and the two sliders 110 are respectively slidably connected to the left inner wall and the right inner wall of the box 100. The left end of the second prism 320 is hinged on the corresponding slider 110, and the slider 110 is used to drive the second prism 320 to slide vertically. It can be understood that the first prism 310 and the second prism 320 are both hinged at the left end, that is, the relatively larger end is hinged, which can improve the mechanical stability of the prism. The hinge can be a damping hinge for easy adjustment, or it can be connected through gear transmission, and the corresponding first prism 310 or second prism 320 is realized through the interlocking of the gears. 0 is adjustable, and by rotating the gear, the corresponding first prism 310 or second prism 320 can be driven to swing. It should be noted that the angle adjustment of the first prism 310 or the second prism 320 is fine-tuned within the range of 5°-10°, and the distance adjustment of the second prism 320 is also fine-tuned at a distance of 5mm-10mm. In order to adapt to the use environment, the adjustment angle and the adjustment distance can also be appropriately enlarged or reduced as needed. The so-called left and right are set based on the direction of the drawing. In fact, the box body 100 is in the shape of a cylinder, and the slider 110 can also be set in the shape of an annular slider. The second prism 320 is hinged behind the disc and then connected to the inside of the annular slider through the disc.

[0052] Reference Figure 5 and Figure 8 The light therapy component 500 includes a light guide 510 and a light therapy cover 520. The light guide 510 is detachably connected to the beam splitter 400. The light guide 510 is arranged in a one-to-one correspondence with the light transmission port 410. One end of the light guide 510 is connected to the corresponding light transmission port 410. A plurality of light therapy covers 520 are provided. The light therapy covers 520 are arranged in a one-to-one correspondence with the light guide 510. The light therapy covers 520 are connected to the other end of the light guide 510. The light therapy covers 520 are used to output colored light to the user. The structure of the light therapy component 500 is simple. The light guide 510 is used to conduct the colored light, which facilitates the light therapy cover 520 to output colored light to the user.

[0053] It can be understood that the light guide 510 can be a flexible light guide rod similar to an optical fiber, or it can be a device with a specially set channel and reflectors set at the corners of the channel, similar to a periscope. Both light guiding methods are applicable to the light guide 510, and the connection method between the light guide 510 and the light transparent port 410 adopts a snap connection method. A snap is set at the lower end of the light transparent port 410 of the splitter plate 400, and a card block is set at one end of the light guide 510. The card block is directly inserted into the snap, so that the light guide 510 is aligned with the light transparent port 410 to achieve light guiding.

[0054] Reference Figure 4 and Figure 8 The phototherapy hood 520 is set in a truncated cone shape, and the hood wall of the phototherapy hood 520 is hollow to form a hood wall space 521. The small end of the phototherapy hood 520 is connected to the other end of the light guide 510, and the large end of the phototherapy hood 520 is used to output colored light to the user. A semiconductor refrigeration plate 600 is embedded in the hood wall of the phototherapy hood 520, and one of the two temperature ends of the semiconductor refrigeration plate 600 is placed in the inner cavity of the phototherapy hood 520, and the other is placed in the hood wall space 521. The hood wall space 521 is connected to a fan 610, and the fan 610 is used to dissipate the heat in the hood wall space 521. The set semiconductor refrigeration plate 600 can adjust the temperature of the output light, so that the output colored light can be easily adapted to the treatment needs.

[0055] Reference Figure 8 A plug interface is provided at the top of the light therapy cover 520, and the plug interface is used to plug in the light guide 510. A light bead 530 is provided at the bottom of the plug interface. A plurality of light beads 530 are provided, and the plurality of light beads 530 are evenly distributed on the inner top of the light therapy cover 520. The light bead 530 is used to disperse the light input by the light guide 510 so that the light covers the entire inner cavity of the light therapy cover 520; at the same time, the light bead 530 can also be replaced by a second convex lens. The distribution of the second convex lens is the same as that of the acupuncture points of a normal person. The second convex lens can accurately guide the colored light to the acupuncture points of the user.

[0056] In some embodiments, the semiconductor refrigeration sheet 600 is a flexible semiconductor refrigeration belt, which is arranged in a ring shape on the cover wall of the phototherapy cover 520. The ring distribution can make the temperature evenly distributed, which is convenient for adjusting the temperature during phototherapy. It can be understood that the flexible semiconductor refrigeration belt is a prior art and can be directly purchased and arranged on the phototherapy cover 520.

[0057] Reference Figure 8 The fan 610 is connected to the hood wall space 521 through the air suction pipe.

[0058] In some embodiments, a light-scattering ball 120 is embedded in the upper end of the box 100, and the light-transmitting hole 211 is snapped on the light-scattering ball 120. The light reflected by the reflector 230 passes through the light-transmitting hole 211 and the light-scattering ball 120 in turn and enters the inner cavity of the box 100. The light-scattering ball 120 is used to scatter the light reflected by the reflector 230, so that the intensity of the light that can be received by the convex lens 240 is reduced, which is more conducive to its sliding and adjusting the convergence or divergence of the light during the sliding process. It can be understood that in order to make the light-scattering ball 120 diverge The light is not absorbed, and a reflective film is set in the space between the convex lens 240 and the top wall of the box body 100. The diffusing ball 120 can reduce the light focusing on the convex lens 240 and prevent the concentrated light from damaging the convex lens 240. The specifications of the diffusing ball 120 can be adjusted. In addition, the diffusing ball 120 can also be replaced with an ultraviolet shielding film or an infrared shielding film. The ultraviolet shielding film only shields ultraviolet rays and allows other visible light to pass through. The infrared shielding film only shields infrared rays and allows other visible light to pass through.
