Description

Technical Field

[0001] The present application relates to the field of phototherapy technology, and in particular to a phototherapy screen. Background Art

[0002] Light therapy screen is an auxiliary means to treat mental, psychological, neurological disorders and other diseases. By using a light therapy screen with a specific wavelength to irradiate the patient at a specific time, it can effectively alleviate the sleep condition and psychological pressure of the patient and related people, and achieve the purpose of treating mental and psychological diseases such as sleep disorders and depression.

[0003] In the related art, a phototherapy screen includes a bottom shell, a light-transmitting cover plate and a light board. The bottom shell and the light-transmitting cover plate form a mounting cavity. The light board is mounted in the mounting cavity. A plurality of lamp beads are arranged on the side of the light board facing the light-transmitting cover plate. The light emitted by the lamp beads is transmitted through the light-transmitting cover plate and dispersed outward. Since there is usually a gap between the lamp beads, bright spots and dark areas may appear on the light-transmitting cover plate. Utility Model Content

[0004] In view of this, an embodiment of the present application provides a light therapy screen to solve the problem of bright spots and dark areas appearing on the light-transmitting cover plate.

[0005] An embodiment of the present application proposes a light therapy screen, comprising a bottom shell, a light-transmitting cover plate, a lamp board and a plurality of side-emitting lamp beads, wherein the light-transmitting cover plate is buckled on the bottom shell, the light-transmitting cover plate and the bottom shell form an installation cavity, the lamp board is arranged in the installation cavity, and the plurality of side-emitting lamp beads are arranged on the side of the light board facing the light-transmitting cover plate.

[0006] The light therapy screen provided in the embodiment of the present application includes a bottom shell, a light-transmitting cover plate, a lamp board and a plurality of side-emitting lamp beads. The lamp board is arranged in an installation cavity surrounded by the light-transmitting cover plate and the bottom shell, and the plurality of side-emitting lamp beads are arranged on the side of the lamp board facing the light-transmitting cover plate, so that the light emitted by the side-emitting lamp beads can pass through the light-transmitting cover plate to the outside; compared with the straight-emitting lamp beads, the light of the side-emitting lamp beads is emitted from the side, which is conducive to the diffusion of light in the installation cavity, ensuring the uniformity of light in the installation cavity, thereby facilitating the uniform transmission of light from the light-transmitting cover plate, so as to improve the problem of bright spots and dark areas appearing on the light-transmitting cover plate.

[0007] In some embodiments, the side-emitting surfaces of the plurality of side-emitting lamp beads face the same direction.

[0008] Since the side emitting surfaces of the multiple side emitting lamp beads face the same direction, the spacing between the multiple side emitting lamp beads can be designed to be the same, which can meet the uniformity of light in the installation cavity and is beneficial to the arrangement of the side emitting lamp beads on the lamp board.

[0009] In some embodiments, the plurality of side-emitting lamp beads are arranged in a plurality of rows in a direction perpendicular to the side-emitting surface, and the side-emitting lamp beads in two adjacent rows are staggered in a direction parallel to the side-emitting surface.

[0010] By adopting the above technical solution, among two adjacent rows of side-emitting lamp beads arranged in a direction perpendicular to the side-emitting surface, the side-emitting lamp beads in one row can illuminate the middle area of ​​two adjacent side-emitting lamp beads in the other row, which is further beneficial to the uniformity of light in the installation cavity and further improves the problem of dark areas appearing on the light-transmitting cover plate.

[0011] In some embodiments, the light therapy screen also includes a diffusion plate fixed to the light board, and the diffusion plate is located between the light board and the light-transmitting cover plate.

[0012] By adopting the above technical solution, the light emitted by the side-emitting lamp beads passes through the diffuser plate and the light-transmitting cover plate in turn, which further improves the problem of bright spots and dark areas on the light-transmitting cover plate. At the same time, the diffuser plate and the lamp board are fixed together, and the two can be installed in the installation cavity as a whole, which is convenient for the assembly of the two.

[0013] In some embodiments, a plurality of receiving grooves are provided on a side of the diffusion plate facing the lamp panel, and the side-emitting lamp beads are arranged in corresponding receiving grooves.

[0014] Since the side-emitting lamp beads are arranged in the corresponding receiving grooves, the light emitted by the side-emitting lamp beads directly enters the diffusion plate for diffusion, thereby further ensuring the uniformity of light diffusion.

[0015] In some embodiments, the diffusion plate and the light panel are clamped and fixed together.

[0016] By adopting the above technical solution, during installation, after aligning the light board with the notch of the installation slot, the light board and the diffuser plate can be fixedly assembled by simply pressing the light board into the installation slot, making the fixed assembly of the light board and the diffuser plate relatively simple.

[0017] In some embodiments, a supporting portion for supporting against the diffusion plate and / or the light board is provided on a side of the light-transmitting cover plate facing the bottom shell.

[0018] By adopting the above technical solution, the light panel and / or the diffuser panel can be pressed into the installation cavity through the light-transmitting cover plate, which is beneficial to the overall assembly of the phototherapy screen.

[0019] In some embodiments, a rotation-stopping structure is provided between the bottom shell and the light-transmitting cover plate and / or between the bottom shell and the diffusion plate.

[0020] By adopting the above technical solution, relative rotation will not occur between the bottom shell and the light-transmitting cover plate and / or between the bottom shell and the diffuser plate, thereby ensuring the overall stability of the phototherapy screen.

[0021] In some embodiments, a translucent layer is provided on the side of the diffuser plate facing the translucent cover plate at a position corresponding to the side-emitting lamp beads; or, the light therapy screen also includes a first diffuser film, which is provided on the side of the diffuser plate facing the translucent cover plate, and a translucent layer is provided on the first diffuser film at a position corresponding to the side-emitting lamp beads.

[0022] Since the brightness of the side-emitting lamp beads is relatively high, a translucent layer is provided on the diffusion plate or the first diffusion film at the position corresponding to the side-emitting lamp beads. The translucent layer can have a certain shielding effect on the side-emitting lamp beads to further improve the bright spot problem.

[0023] In some embodiments, the light therapy screen further comprises a second diffusion film, wherein the second diffusion film is located between the light-transmitting cover plate and the translucent layer.

[0024] Although adding a translucent layer can effectively improve bright spots, there will still be a slight difference in light and dark between the translucent layer and its surroundings. By adding a second diffusion film to diffuse the light, the uniformity of the light can be further improved.

[0025] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification.

[0054] In the related art, a phototherapy screen includes a bottom shell, a light-transmitting cover plate and a light board. The bottom shell and the light-transmitting cover plate form a mounting cavity. The light board is mounted in the mounting cavity. A plurality of lamp beads are arranged on the side of the light board facing the light-transmitting cover plate. The light emitted by the lamp beads is transmitted through the light-transmitting cover plate and dispersed outward. Since there is usually a gap between the lamp beads, bright spots and dark areas may appear on the light-transmitting cover plate.

[0055] In order to solve the problem of bright spots and dark areas appearing on a light-transmitting cover plate, the present application provides a light therapy screen.

[0056] The embodiment of the present application provides a light therapy screen. Figure 1 and Figure 2 The light therapy screen 10 includes a bottom shell 11, a light-transmitting cover plate 12, a lamp board 13 and a plurality of side-emitting lamp beads 14. The light-transmitting cover plate 12 is buckled on the bottom shell 11. The light-transmitting cover plate 12 and the bottom shell 11 form an installation cavity 15. The lamp board 13 is arranged in the installation cavity 15. The plurality of side-emitting lamp beads 14 are arranged on the side of the lamp board 13 facing the light-transmitting cover plate 12.

[0057] The shape of the bottom shell 11 is not limited in this application, as long as it can accommodate the light board 13. It is understood that the bottom shell 11 can be a regular shape, such as a circle, a rectangle, etc.; the bottom shell 11 can also be an irregular shape. Among them, the material of the bottom shell 11 can be a variety of materials, as long as it is opaque, for example, the bottom shell 11 can be made of metal, plastic, etc.

[0058] The shape of the light-transmitting cover plate 12 is not limited in the present application. It is understood that the light-transmitting cover plate 12 can be a regular shape, such as a circle, a rectangle, etc.; the light-transmitting cover plate 12 can also be an irregular shape.

[0059] The transparent cover plate 12 can be made of various materials as long as it is transparent, for example, the transparent cover plate 12 can be made of plastic, glass, etc. The transparent cover plate 12 itself has a certain function of diffusing light sources.

[0060] It should be noted that the transparent cover plate 12 may have a shape different from that of the bottom case 11 , or may be different from the shape of the bottom case 11 .

[0061] There are many ways to buckle the light-transmitting cover plate 12 onto the bottom shell 11, such as snap connection, bonding, threaded connection or fixing with fasteners.

[0062] It is understandable that the installation cavity 15 can be a regular cavity, such as a circular cavity, a rectangular cavity, etc.; the installation cavity 15 can also be an irregular cavity. The installation cavity 15 needs to have a certain depth to meet the installation of the light board 13.

[0063] The shape of the light board 13 is not limited in this application. It is understood that the light board 13 can be a regular shape, such as a circle, a rectangle, etc.; the light board 13 can also be an irregular shape. It should be noted that the light board 13 can be different from the shape of the installation cavity 15, or can be different from the shape of the installation cavity 15.

[0064] The side-emitting lamp bead 14 means that the light is emitted from the side, that is, the emitted light will not directly pass through the light-transmitting cover plate 12, but will be reflected at least once in the installation cavity 15 before passing through the light-transmitting cover plate 12 to pass through. This is conducive to the diffusion of light in the installation cavity 15 and ensures the uniformity of light in the installation cavity 15.

[0065] The plurality of side-emitting lamp beads 14 are arranged at intervals, and the interval distance between two adjacent side-emitting lamp beads 14 can be set as required. The interval distance between two adjacent side-emitting lamp beads 14 can be the same or different.

[0066] The light therapy screen 10 provided in the embodiment of the present application includes a bottom shell 11, a light-transmitting cover plate 12, a lamp board 13 and a plurality of side-emitting lamp beads 14. The lamp board 13 is arranged in an installation cavity 15 surrounded by the light-transmitting cover plate 12 and the bottom shell 11. The plurality of side-emitting lamp beads 14 are arranged on the side of the lamp board 13 facing the light-transmitting cover plate 12, so that the light emitted by the side-emitting lamp beads 14 can pass through the light-transmitting cover plate 12 to the outside; compared with the direct-emitting lamp beads, the light of the side-emitting lamp beads 14 is emitted from the side and will not directly hit the light-transmitting cover plate 12, which is beneficial to the diffusion of light in the installation cavity 15, ensuring the uniformity of light in the installation cavity 15, thereby facilitating the uniform transmission of light from the light-transmitting cover plate 12, so as to improve the problem of bright spots and dark areas appearing on the light-transmitting cover plate 12.

[0067] Please also refer to Figure 3 and Figure 6 In some embodiments, the side-emitting surfaces 141 of the plurality of side-emitting lamp beads 14 face the same direction.

[0068] Optionally, the side-emitting lamp bead 14 has only one side-emitting surface 141 .

[0069] The side emitting surfaces 141 of the plurality of side emitting lamp beads 14 have the same orientation, which means that the side emitting surfaces 141 of the plurality of side emitting lamp beads 14 are parallel to the Figure 6 The side-emitting surfaces 141 of the side-emitting lamp beads 14 face the same side.

[0070] Since the side emitting surfaces 141 of the multiple side emitting lamp beads 14 face the same direction, the spacing between the multiple side emitting lamp beads 14 can be designed to be the same, which can meet the uniformity of light in the installation cavity 15 and is beneficial to the arrangement of the side emitting lamp beads 14 on the lamp board 13.

[0071] In other embodiments, the side light emitting surfaces 141 of the plurality of side light emitting lamp beads 14 may be oriented in different directions. To ensure uniformity of light in the mounting cavity 15 , the spacing between the plurality of side light emitting lamp beads 14 needs to be designed to be different.

[0072] Please refer to Figure 6 In some embodiments, the plurality of side-emitting lamp beads 14 are arranged in multiple rows in a direction perpendicular to the side-emitting surface 141 , and the side-emitting lamp beads 14 in two adjacent rows are staggered in a direction parallel to the side-emitting surface 141 .

[0073] The direction perpendicular to the side light emitting surface 141 refers to Figure 6 The Y direction indicated by the middle arrow is parallel to the side light emitting surface 141. Figure 6 The X direction is indicated by the arrow.

[0074] By adopting the above-mentioned technical solution, among the two adjacent rows of side-emitting lamp beads 14 arranged in the Y direction, the side-emitting lamp beads 14 in one row can illuminate the middle area of ​​the two adjacent side-emitting lamp beads 14 in the other row, which is further beneficial to the uniformity of light in the installation cavity 15 and further improves the problem of dark areas appearing in the light-transmitting cover plate 12.

[0075] In other embodiments, based on the fact that a plurality of side-emitting lamp beads 14 are arranged in a plurality of rows in a direction perpendicular to the side-emitting surface 141 , the side-emitting lamp beads 14 in two adjacent rows may be arranged in a direction parallel to the side-emitting surface 141 .

[0076] In other embodiments, the plurality of side-emitting lamp beads 14 may be arranged in a disorderly manner.

[0077] In some embodiments, the light therapy screen 10 further includes a diffusion plate 16 fixed to the light board 13 , and the diffusion plate 16 is located between the light board 13 and the light-transmitting cover plate 12 .

[0078] The diffusion plate 16 is made of a transparent or translucent material, such as organic glass, polycarbonate, acrylic, etc. The main function of the diffusion plate 16 is to diffuse the light evenly, so as to achieve the effect of even light distribution.

[0079] When in use, the light emitted by the side-emitting lamp beads 14 passes through the diffusion plate 16 and the light-transmitting cover plate 12 in sequence and is transmitted outward, further improving the problem of bright spots and dark areas on the light-transmitting cover plate 12 .

[0080] At the same time, the diffusion plate 16 and the lamp panel 13 are fixed together, and the two can be installed in the installation cavity 15 as a whole, which is beneficial to the assembly of the two.

[0081] In other embodiments, when the side-emitting lamp beads 14 have already achieved uniform light distribution, the diffuser 16 may not be provided.

[0082] In other embodiments, the diffusion plate 16 and the light board 13 may not be fixed together, but may be separately installed in the installation cavity 15 .

[0083] Please also refer to Figure 2 and Figure 7 In some embodiments, a plurality of receiving grooves 1611 are provided on a side of the diffusion plate 16 facing the lamp board 13 , and the side-emitting lamp beads 14 are provided in corresponding receiving grooves 1611 .

[0084] Optionally, the shape of the accommodating groove 1611 is adapted to the side-emitting lamp bead 14, and the size of the accommodating groove 1611 is slightly larger than the size of the side-emitting lamp bead 14, so that there is a certain gap between the side-emitting lamp bead 14 and the groove wall of the accommodating groove 1611, so as to avoid damage to the side-emitting lamp bead 14 when the diffuser plate 16 and the lamp board 13 are fixed together, especially damage to the side-emitting surface 141, which affects the normal light emission of the side-emitting lamp bead 14.

[0085] Since the side-emitting lamp beads 14 are arranged in the corresponding receiving grooves 1611 , the light emitted by the side-emitting lamp beads 14 directly enters the diffusion plate 16 for diffusion, thereby further ensuring the uniformity of light diffusion.

[0086] In other embodiments, the receiving groove 1611 for receiving the side-emitting lamp beads 14 may not be provided on the side of the diffusion plate 16 facing the lamp board 13 .

[0087] Please also refer to Figure 2 , Figure 6 and Figure 7 In some embodiments, the diffuser plate 16 and the light board 13 are snap-fitted and fixed together.

[0088] Specifically, the diffuser plate 16 includes a diffuser plate body 161 and a fixed ring edge 162, the fixed ring edge 162 is at the edge of the diffuser plate body 161, and the accommodating groove 1611 is arranged on the side of the diffuser plate body 161 facing the lamp board 13; the fixed ring edge 162 and the diffuser plate body 161 form a mounting groove 163 for mounting the lamp board 13, and a plurality of third clamping portions 1621 are arranged on the inner side of the fixed ring edge 162, and a plurality of third clamping portions 1621 are arranged at circumferential intervals along the fixed ring edge 162; when the lamp board 13 is installed in the mounting groove 163, the plurality of third clamping portions 1621 are clamped on the edge of the lamp board 13 to fix the lamp board 13 in the mounting groove 163, thereby fixing the lamp board 13 and the diffuser plate 16 together.

[0089] Optionally, the diffusion plate 16 and the light board 13 are both circular.

[0090] By adopting the above technical solution, during installation, after the lamp board 13 is aligned with the notch of the mounting groove 163, the lamp board 13 and the diffuser plate 16 can be fixedly assembled by simply pressing the lamp board 13 into the mounting groove 163, making the fixed assembly of the lamp board 13 and the diffuser plate 16 relatively simple.

[0091] In other embodiments, the diffusion plate 16 may be fixed to the light board 13 by, but not limited to, bonding, screw connection, or the like.

[0092] Please refer to Fig. 9 In some embodiments, a supporting portion 123 for supporting against the diffusion plate 16 and / or the light board 13 is provided on a side of the light-transmitting cover plate 12 facing the bottom shell 11 .

[0093] Optionally, the abutting portion 123 is located at an edge of the light-transmitting cover plate 12 to avoid affecting the emission of light.

[0094] It can be understood that the abutting portion 123 may be an annular structure, or a plurality of abutting portions 123 may be arranged at intervals along the circumference of the light-transmitting cover plate 12 .

[0095] It can be understood that when the diffuser plate 16 is not provided, the abutting portion 123 can abut against the edge of the lamp board 13. When the diffuser plate 16 is provided, the abutting portion 123 can abut against the edge of the diffuser plate 16, or the abutting portion 123 can abut against the edge of the lamp board 13; when there are multiple abutting portions 123, some of the abutting portions 123 can abut against the edge of the diffuser plate 16, or some of the abutting portions 123 can abut against the edge of the lamp board 13; wherein, if the abutting portion 123 is to abut against the edge of the lamp board 13, it is necessary to make the size of the diffuser plate 16 smaller than the size of the lamp board 13 to expose the edge of the lamp board 13, or to provide an avoidance hole or avoidance gap on the diffuser plate 16 for the abutting portion 123 to pass through.

[0096] By adopting the above technical solution, the light panel 13 and / or the diffuser panel 16 can be pressed into the installation cavity 15 through the light-transmitting cover plate 12 , which is beneficial to the overall assembly of the phototherapy screen 10 .

[0097] In other embodiments, the diffuser plate 16 and / or the light board 13 may be fixed in the mounting cavity 15 by bonding with light-guiding adhesive.

[0098] In some embodiments, a rotation-stopping structure is provided between the bottom shell 11 and the light-transmitting cover plate 12 and / or between the bottom shell 11 and the diffusion plate 16 .

[0099] By adopting the above technical solution, relative rotation will not occur between the bottom shell 11 and the light-transmitting cover plate 12 and / or between the bottom shell 11 and the diffuser plate 16 , thereby ensuring the overall stability of the phototherapy screen 10 .

[0100] In other embodiments, when the bottom shell 11 and the light-transmitting cover plate 12 and / or the bottom shell 11 and the diffuser plate 16 are fixed by bonding, screw connection, etc., the anti-rotation structure may not be provided.

[0101] Please also refer to Figure 4 , Figure 5 and Figure 7 In some embodiments, the anti-rotation structure includes an anti-rotation protrusion and an anti-rotation recess. The anti-rotation protrusion is provided on the bottom shell 11, and the anti-rotation recess is provided on the transparent cover plate 12 and / or the diffuser plate 16.

[0102] Optionally, the anti-rotation protrusion includes a first anti-rotation protrusion 111 and a second anti-rotation protrusion 112 provided on the side of the bottom shell 11, a first anti-rotation recess 121 is provided on the light-transmitting cover plate 12, and a second anti-rotation recess 1622 is provided on the outer side of the fixed ring edge 162 on the diffuser plate 16. During installation, the diffuser plate 16 and the light board 13 are first fixed together, and then the diffuser plate 16 and the light board 13 are installed into the installation cavity 15 together, and the second anti-rotation recess 1622 is anti-rotated with the second anti-rotation protrusion 112 to ensure that the diffuser plate 16 and the light board 13 will not rotate relative to the bottom shell 11 in the installation cavity 15; finally, the light-transmitting cover plate 12 is buckled onto the bottom shell 11, and at this time, the first anti-rotation recess 121 is anti-rotated with the first anti-rotation protrusion 111 to ensure that the light-transmitting cover plate 12 will not rotate relative to the bottom shell 11.

[0103] Optionally, the first anti-rotation protrusion 111 and the second anti-rotation protrusion 112 are arranged in alignment to facilitate the processing of the two. Wherein, multiple first anti-rotation protrusions 111 and second anti-rotation protrusions 112 can be arranged at intervals along the circumference of the bottom shell 11 to further ensure the stability of the anti-rotation fit, and at the same time facilitate the uniform force of the anti-rotation recess and the anti-rotation protrusion.

[0104] Optionally, an annular step 115 is provided on the side of the bottom shell 11 , and the first anti-rotation protrusion 111 is located on the annular step 115 .

[0105] By providing the anti-rotation protrusion on the bottom shell 11 , the bottom shell 11 does not need to be designed to be too thick while ensuring the strength of the bottom shell 11 , which is beneficial to reducing the overall weight of the phototherapy screen 10 .

[0106] In other embodiments, the anti-rotation recess may be provided on the bottom shell 11 , and the anti-rotation protrusion may be provided on the light-transmitting cover plate 12 and / or the diffuser plate 16 .

[0107] In other embodiments, the second anti-rotation protrusion 112 may be provided only on the bottom shell 11 , and the second anti-rotation recess 1622 may be provided on the diffuser plate 16 ; or, the first anti-rotation protrusion 111 may be provided only on the bottom shell 11 , and the first anti-rotation recess 121 may be provided on the light-transmitting cover plate 12 .

[0108] like Figure 3 and Figure 8 As shown, in some embodiments, the light therapy screen 10 also includes a first diffusion film 17, which is disposed on the side of the diffusion plate 16 facing the transparent cover plate 12, and a translucent layer 171 is provided on the first diffusion film 17 at a position corresponding to the side light-emitting lamp beads 14.

[0109] A semi-transparent layer 171 is disposed on the first diffusion film 17 at a position corresponding to each side-emitting lamp bead 14 .

[0110] Optionally, the semi-transparent layer 171 is a silk-screen layer, that is, coated on the first diffusion film 17 by silk-screen printing. The semi-transparent layer 171 may be a white silk-screen layer.

[0111] The first diffusion film 17 is made of a transparent or translucent material, such as organic glass, polycarbonate, acrylic, etc. Optionally, the first diffusion film 17 is bonded and fixed on the diffusion plate 16 .

[0112] By adopting the above technical solution, the first diffusion film 17 can further diffuse the light passing through the diffusion plate 16, thereby further achieving the effect of uniform light distribution. At the same time, since the position of the side-emitting lamp beads 14 has relatively high brightness, a translucent layer 171 is provided on the first diffusion film 17 at the position corresponding to the side-emitting lamp beads 14. The translucent layer 171 can have a certain shielding effect on the side-emitting lamp beads 14, so as to further improve the problem of bright spots.

[0113] In other embodiments, the first diffusion film 17 is not provided, and a translucent layer 171 is provided on the side of the diffusion plate 16 facing the transparent cover plate 12 at a position corresponding to the side-emitting lamp beads 14; optionally, the translucent layer 171 is coated on the diffusion plate 16 by screen printing. By providing the translucent layer 171 at a position corresponding to the side-emitting lamp beads 14 on the diffusion plate 16, the translucent layer 171 can have a certain shielding effect on the side-emitting lamp beads 14, so as to further improve the problem of bright spots.

[0114] like Figure 2 and Figure 3 As shown, the light therapy screen 10 further includes a second diffusion film 18 , which is located between the light-transmitting cover plate 12 and the translucent layer 171 .

[0115] Optionally, the second diffusion film 18 is a PET diffusion film.

[0116] Optionally, the second diffusion film 18 is press-fitted between the light-transmitting cover plate 12 and the bottom shell 11 .

[0117] Although adding the semi-transparent layer 171 can effectively improve the bright spots, there is still a slight difference in brightness between the semi-transparent layer 171 and its surroundings. By adding the second diffusion film 18 to diffuse the light, the uniformity of the light can be further improved.

[0118] like Figure 4 and Figure 5 As shown, in some embodiments, the light-transmitting cover plate 12 is snap-fitted and fixed on the bottom shell 11 .

[0119] Specifically, a first clamping portion 113 is provided on the bottom shell 11, and a second clamping portion 122 is provided on the transparent cover plate 12. When the transparent cover plate 12 is buckled on the bottom shell 11, the first clamping portion 113 and the second clamping portion 122 are engaged with each other to fix the transparent cover plate 12 on the bottom shell 11.

[0120] Optionally, multiple first clamping portions 113 are arranged at intervals along the circumference of the bottom shell 11, and multiple second clamping portions 122 are arranged at intervals along the circumference of the transparent cover plate 12. The stability of the transparent cover plate 12 being fixed on the bottom shell 11 is ensured by clamping and matching the multiple first clamping portions 113 and the multiple second clamping portions 122.

[0121] By adopting the above technical solution, during installation, after aligning the light-transmitting cover plate 12 with the bottom shell 11, it is only necessary to press the light-transmitting cover plate 12 onto the bottom shell 11 to achieve fixed assembly of the light-transmitting cover plate 12 and the bottom shell 11, making the fixed assembly of the light-transmitting cover plate 12 and the bottom shell 11 relatively simple.

[0122] In other embodiments, the light-transmitting cover plate 12 may be fixed to the bottom shell 11 by bonding, screw connection, or the like.

[0123] In some embodiments, if the light therapy screen 10 has certain requirements on sealing, an annular sealing ring can be provided between the light-transmitting cover plate 12 and the bottom shell 11 .

[0124] In some embodiments, the light board 13 is a circuit board.

[0125] In some embodiments, the side-emitting lamp beads 14 are RGB lamp beads to provide a multi-color light source; Figure 4 As shown, a wire hole 114 is provided at the bottom of the bottom shell 11, and the circuit passes through the wire hole 114 and is connected to the light board 13 to control the switch and color change of the light therapy screen 10. According to the color change, a corresponding pattern can be displayed on the transparent cover plate 12 to assist in the treatment of mental, psychological, neurological disorders and other diseases.
