[0039] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1-Figure 5The light-transmitting member 100 for the beauty instrument 400 according to the first embodiment of the utility model is described. The light-transmitting member 100 can be used for the electrode head 300 of the beauty instrument 400. In the following description of the present application, the light-transmitting member 100 is used for the electrode head 300 of the beauty instrument 400 as an example for explanation.

[0040] like Figure 1-Figure 5 As shown, the light-transmitting member 100 for the beauty instrument 400 according to the first aspect of the embodiment of the utility model includes a body 1, a first light guide column 2 and a second light guide column 3.

[0041] Specifically, the first light guide column 2 and the second light guide column 3 are both arranged on one side surface of the body 1 in the thickness direction, the first light guide column 2 and the second light guide column 3 extend along the thickness direction of the light-transmitting member 100, the free end surface of the first light guide column 2 is formed as a plane, and the free end surface of the second light guide column 3 is formed as an arc surface convex toward the side away from the body 1. For example, Figure 1-Figure 5 In the example, the first light guide column 2 and the second light guide column 3 are arranged on the lower side of the main body 1, the upper end of the first light guide column 2 and the upper end of the second light guide column 3 are respectively connected to the lower side of the main body 1, the lower surface of the first light guide column 2 is the free end face of the first light guide column 2, the lower surface of the second light guide column 3 is the free end face of the second light guide column 3, the free end face of the second light guide column 3 is a downwardly convex arc surface, and the wavelength of the light passing through the first light guide column 2 is greater than the wavelength of the light passing through the second light guide column 3.

[0042] When the light-transmitting member 100 is assembled with the lamp board 201 of the lamp board assembly 200, the lamp beads emitting different light on the lamp board 201 are respectively opposite to the first light guide column 2 or the second light guide column 3. For example, when the lamp board 201 is provided with a first lamp bead 202 emitting red light and a second lamp bead 203 emitting yellow light, the first lamp bead 202 is arranged opposite to the first light guide column 2, and the second lamp bead 203 is arranged opposite to the second light guide column 3. Since the frequency and wavelength of light entering the medium (such as the light-transmitting member 100) will change, the longer the wavelength, the smaller the frequency, and the less the change, when the light of the first lamp bead 202 emitting red light enters the light-transmitting member 100, the refraction angle is small, and the free end surface of the first light guide column 2 can be formed into a plane. The frequency of the second lamp bead 203 emitting yellow light is higher, and it is more affected by the medium, with a large frequency change and a large change in wave velocity, so the refractive index is large. Therefore, a second curved light guide column 3 is used to change the refraction angle to ensure that the angle of the light emitted after refraction is consistent with the angle of the light emitted by the first lamp bead 202 after refraction.

[0043] Thus, on the one hand, the light on the lamp board 201 opposite to the light-transmitting member 100 passes through the first light guide column 2 and the second light guide column 3 and is irradiated from the other side surface in the thickness direction of the main body 1. The light on the lamp board 201 is gathered by the first light guide column 2 and the second light guide column 3, and then irradiates a relatively uniform light from the upper surface of the main body 1. That is, the first light guide column 2 and the second light guide column 3 respectively have the function of focusing light, which can reduce the light irradiation to other positions on the lower surface of the main body 1, thereby reducing light loss and improving the utilization rate of light. On the other hand, by setting the free end face of the first light guide column 2 and the free end face of the second light guide column 3 to be different, the irradiation angle of the light passing through the first light guide column 2 and the second light guide column 3 is roughly the same, thereby improving the uniformity of the light irradiated from the light-transmitting member 100, being more conducive to the use of the light-transmitting member 100, and improving the use performance and use effect of the light-transmitting member 100. In addition, the first light guide column 2 and the second light guide column 3 have a simple structure, are easy to produce, and are less difficult to produce.

[0044] According to the light-transmitting member 100 for the beauty instrument 400 of the embodiment of the utility model, by setting the first light-guiding column 2 and the second light-guiding column 3, the first light-guiding column 2 and the second light-guiding column 3 respectively have the function of focusing light, thereby reducing light loss and improving the utilization rate of light. In addition, by setting the free end face of the first light-guiding column 2 and the free end face of the second light-guiding column 3 to be different, the irradiation angles of the light passing through the first light-guiding column 2 and the second light-guiding column 3 are roughly the same, thereby improving the uniformity of the light emitted from the light-transmitting member 100, being more conducive to the use of the light-transmitting member 100, and improving the use performance and use effect of the light-transmitting member 100. In addition, the first light-guiding column 2 and the second light-guiding column 3 have simple structures, are easy to produce, and have low production difficulty.

[0045] According to some embodiments of the present invention, Figure 3-Figure 5 , the cross-sectional area of ​​the first light guide column 2 gradually decreases along the side away from the body 1. And / or, the cross-sectional area of ​​the second light guide column 3 gradually decreases along the side away from the body 1. The above-mentioned settings of the first light guide column 2 and the second light guide column 3 include the following situations: First, only the cross-sectional area of ​​the first light guide column 2 gradually decreases along the side away from the body 1. Second, only the cross-sectional area of ​​the second light guide column 3 gradually decreases along the side away from the body 1. Third, the cross-sectional area of ​​the first light guide column 2 and the cross-sectional area of ​​the second light guide column 3 respectively gradually decrease along the side away from the body 1.

[0046] For example, in Figure 3-Figure 5In the example, the cross-sectional area of ​​the side of the first light guide column 2 connected to the body 1 is larger than the cross-sectional area of ​​the free end of the first light guide column 2, and the cross-sectional area of ​​the side of the second light guide column 3 connected to the body 1 is larger than the cross-sectional area of ​​the free end of the second light guide column 3. When the light emitted by the first lamp bead 202 opposite to the first light guide column 2 is irradiated onto the first light guide column 2, it is irradiated from the upper surface of the body 1 after being refracted by the first light guide column 2. Thus, the cross-sectional area of ​​the first light guide column 2 is gradually reduced along the side away from the body 1 by setting, that is, when the light irradiated into the first light guide column 2 from the free end of the first light guide column 2 propagates in the first light guide column 2, the closer to the body 1, the larger the irradiation range of the light, so that the side of the first light guide column 2 connected to the body 1 will not hinder the propagation and divergence of the light, and also make the range of the light irradiated from the body 1 larger, which is more conducive to the propagation of the light in the first light guide column 2, and thus make the light irradiated from the body 1 more uniform.

[0047] When the light emitted by the second lamp bead 203 opposite to the second light guide column 3 is irradiated onto the second light guide column 3, it is irradiated from the upper surface of the body 1 after being refracted by the second light guide column 3. Therefore, when the light irradiated into the second light guide column 3 from the free end of the second light guide column 3 propagates in the second light guide column 3, the closer to the body 1, the larger the irradiation range of the light, so that the side of the second light guide column 3 connected to the body 1 will not hinder the propagation and divergence of the light, and also make the range of the light irradiated from the body 1 larger, which is more conducive to the propagation of the light in the second light guide column 3, and further make the light irradiated from the body 1 more uniform.

[0048] According to some embodiments of the present invention, Figure 3-Figure 5 , along the side away from the main body 1, the outer circumference of the first light guide column 2 is bent and extended in the direction close to the central axis of the first light guide column 2. And / or, along the side away from the main body 1, the outer circumference of the second light guide column 3 is bent and extended in the direction close to the central axis of the second light guide column 3. The above-mentioned settings of the first light guide column 2 and the second light guide column 3 include the following situations: First, along the side away from the main body 1, only the outer circumference of the first light guide column 2 is bent and extended in the direction close to the central axis of the first light guide column 2. Second, along the side away from the main body 1, only the outer circumference of the second light guide column 3 is bent and extended in the direction close to the central axis of the second light guide column 3. Third, along the side away from the main body 1, the outer circumference of the first light guide column 2 is bent and extended in the direction close to the central axis of the first light guide column 2, and the outer circumference of the second light guide column 3 is bent and extended in the direction close to the central axis of the second light guide column 3.

[0049] For example, in Figure 3-Figure 5In the example, the outer circumference of the side of the first light guide column 2 connected to the body 1 is smoothly transitioned toward the outer circumference of the free end of the first light guide column 2, and the side of the first light guide column 2 is transitioned by a curved surface with a uniform curvature. This arrangement can ensure that more light irradiated on the first light guide column 2 can be fully reflected by the wall surface of the first light guide column 2, thereby reducing light loss. In addition, the appearance of the first light guide column 2 is also more exquisite. For example, in Figure 3-Figure 5 In the example, the outer peripheral surface of the side of the second light guide column 3 connected to the body 1 is smoothly transitioned toward the outer peripheral surface of the free end of the second light guide column 3, and the side surface of the second light guide column 3 adopts a curved surface transition with uniform curvature. Such a setting can ensure that the light irradiated on the second light guide column 3 can be more totally reflected by the wall surface of the second light guide column 3, thereby reducing light loss. Moreover, the appearance of the second light guide column 3 is also more exquisite. It should be noted that the curvature of the side surface of the first light guide column 2 and the curvature of the side surface of the second light guide column 3 can be set according to actual conditions to better meet practical applications.

[0050] According to some embodiments of the utility model, the outer peripheral surface of the end of the first light guide column 2 away from the body 1 has an inclination angle of α1 relative to the free end surface of the first light guide column 2, and the extension line of the outer peripheral surface of the end of the first light guide column 2 close to the body 1 has an inclination angle of β1 relative to the surface of the body 1, wherein α1 and β1 respectively satisfy: 95°≤α1≤100°, 50°≤β1≤55°. And / or, the outer peripheral surface of the end of the second light guide column 3 away from the body 1 has an inclination angle of α2 relative to the cross-section of the free end of the second light guide column 3, and the extension line of the outer peripheral surface of the end of the second light guide column 3 close to the body 1 has an inclination angle of β2 relative to the surface of the body 1, wherein α2 and β2 respectively satisfy: 95°≤α2≤100°, 50°≤β2≤55°.

[0051] For example, in Figure 4In the example, the angle between the tangent line at the connection between the lower end face of the first light guide column 2 and the side face of the first light guide column 2 and the plane where the lower end face of the first light guide column 2 is located is α1, and the angle between the tangent line at the connection between the side face of the first light guide column 2 and the lower surface of the body 1 and the plane where the lower surface of the body 1 is located is β1. When the inclination angle α1 of the outer peripheral surface of the end of the first light guide column 2 away from the body 1 relative to the free end face of the first light guide column 2 is less than 95°, the outer peripheral surface of the lower end of the first light guide column 2 is substantially perpendicular to the lower end face of the first light guide column 2, which reduces the irradiation range of the light irradiated onto the first light guide column 2, and the outer peripheral surface of the lower end of the first light guide column 2 is likely to hinder the propagation of light, which is not conducive to the propagation of light on the first light guide column 2. When the inclination angle α1 of the outer peripheral surface of the end of the first light guide column 2 away from the main body 1 relative to the free end surface of the first light guide column 2 is greater than 100°, the volume of the lower end of the first light guide column 2 is increased, thereby increasing the volume of the first light guide column 2, increasing the space occupied by the first light guide column 2 on the main body 1, and reducing the number of first light guide columns 2 that can be set on the main body 1, which is not conducive to the use of the light-transmitting member 100.

[0052] When the inclination angle β1 of the extension line of the outer peripheral surface of the end of the first light guide column 2 close to the body 1 relative to the surface of the body 1 is less than 50°, the inclination angle of the side of the first light guide column 2 relative to the surface of the body 1 is large, and the angle between the light irradiated from the first light guide column 2 and the body 1 is small, and the light is not easy to irradiate the user's skin. When the inclination angle β1 of the extension line of the outer peripheral surface of the end of the first light guide column 2 close to the body 1 relative to the surface of the body 1 is greater than 55°, the inclination angle of the side of the first light guide column 2 relative to the surface of the body 1 is small, which reduces the irradiation range of the light irradiated from the first light guide column 2.

[0053] Thus, by setting the inclination angle α1 of the outer peripheral surface of the end of the first light guide column 2 away from the body 1 to the free end surface of the first light guide column 2 to meet the following conditions: 95°≤α1≤100°, and the inclination angle β1 of the extension line of the outer peripheral surface of the end of the first light guide column 2 close to the body 1 to the surface of the body 1 to meet the following conditions: 50°≤β1≤55°, the inclination angle of the outer peripheral surface of the lower end of the first light guide column 2 and the inclination angle of the outer peripheral surface of the upper end of the first light guide column 2 are both reasonably set, which is conducive to the propagation of light on the first light guide column 2. At the same time, the size of the first light guide column 2 is moderate, which is conducive to setting a plurality of first light guide columns 2 on the body 1, thereby improving the surface utilization rate of the body 1.

[0054] For example, in Figure 5In the example, the angle between the tangent line at the connection between the lower end of the second light guide column 3 and the side surface of the second light guide column 3 and the cross-section of the lower end of the second light guide column 3 is α2, and the angle between the tangent line at the connection between the side surface of the second light guide column 3 and the lower surface of the body 1 and the plane where the lower surface of the body 1 is located is β2. The above-mentioned "cross-section" refers to the section along the horizontal direction at the connection between the side surface of the second light guide column 3 and the lower end surface of the second light guide column 3.

[0055] When the inclination angle α2 of the outer circumference of the end of the second light guide column 3 away from the body 1 relative to the cross-section of the free end of the second light guide column 3 is less than 95°, the outer circumference of the lower end of the second light guide column 3 is substantially perpendicular to the lower end face of the second light guide column 3, which reduces the irradiation range of the light irradiated onto the second light guide column 3. The outer circumference of the lower end of the second light guide column 3 is likely to hinder the propagation of light, which is not conducive to the propagation of light on the second light guide column 3. When the inclination angle α2 of the outer circumference of the end of the second light guide column 3 away from the body 1 relative to the cross-section of the free end of the second light guide column 3 is greater than 100°, the volume of the lower end of the second light guide column 3 is increased, thereby increasing the volume of the second light guide column 3, increasing the space occupied by the second light guide column 3 on the body 1, reducing the number of second light guide columns 3 that can be set on the body 1, and being not conducive to the use of the light-transmitting member 100.

[0056] When the inclination angle β2 of the extension line of the outer peripheral surface of the end of the second light guide column 3 close to the body 1 relative to the surface of the body 1 is less than 50°, the inclination angle of the side of the second light guide column 3 relative to the surface of the body 1 is large, and the angle between the light irradiated from the second light guide column 3 and the body 1 is small, and the light is not easy to irradiate the user's skin. When the inclination angle β2 of the extension line of the outer peripheral surface of the end of the second light guide column 3 close to the body 1 relative to the surface of the body 1 is greater than 55°, the inclination angle of the side of the second light guide column 3 relative to the surface of the body 1 is small, which reduces the irradiation range of the light irradiated from the second light guide column 3.

[0057] Thus, by setting the inclination angle α2 of the outer peripheral surface of the end of the second light guide column 3 away from the body 1 relative to the cross-section of the free end of the second light guide column 3 to meet the following conditions: 95°≤α2≤100°, the inclination angle β2 of the extension line of the outer peripheral surface of the end of the second light guide column 3 close to the body 1 relative to the surface of the body 1 to meet the following conditions: 50°≤β2≤55°, the inclination angle of the outer peripheral surface of the lower end of the second light guide column 3 is reasonably set, and the inclination angle of the outer peripheral surface of the upper end of the second light guide column 3 relative to the body 1 is also reasonably set, which is conducive to the propagation of light on the second light guide column 3. At the same time, the size of the second light guide column 3 is moderate, which is conducive to setting a plurality of second light guide columns 3 on the body 1, thereby improving the surface utilization rate of the body 1.

[0058] Optionally, the outer circumference of the first light guide column 2 is coated with a first diffuse reflection layer. And / or, the outer circumference of the second light guide column 3 is coated with a second diffuse reflection layer. For example, the outer circumference of the first light guide column 2 and the outer circumference of the second light guide column 3 refer to the side of the first light guide column 2 and the side of the second light guide column 3, respectively. Thus, by providing a first diffuse reflection layer on the outer circumference of the first light guide column 2 and a second diffuse reflection layer on the outer circumference of the second light guide column 3, the light irradiated onto the first light guide column 2 forms a diffuse reflection in the first light guide column 2, and the light irradiated onto the second light guide column 3 forms a diffuse reflection in the second light guide column 3, so that the light irradiated from the first light guide column 2 and the second light guide column 3 onto the main body 1 is more divergent and uniform, which is more conducive to the use of the light-transmitting member 100. It should be noted that the first diffuse reflection layer and the second diffuse reflection layer can be set to the same coating or different coatings, which is not specifically limited here.

[0059] According to some embodiments of the present invention, the free end surface of the first light guide column 2 is circular, and the diameter of the free end surface of the first light guide column 2 is d, where d satisfies: 3.2mm≤d≤4.5mm. And / or, the free end surface of the second light guide column 3 constitutes a part of the spherical surface of a sphere, and the radius of the sphere is R, where R satisfies: R≥14.3mm.

[0060] like Figure 2 As shown, the free end face of the first light guide column 2 is in a circular shape. As a result, the circular surface area is larger, so that the light of the first lamp bead 202 opposite to the first light guide column 2 can be irradiated onto the first light guide column 2 as much as possible, so as to further reduce light loss. In addition, the first light guide column 2 has a beautiful appearance and a simple structure, which is conducive to the production and processing of the first light guide column 2.

[0061] Furthermore, combined with Figure 2 and Figure 4, the diameter of the free end face of the first light guide column 2 is d, where d satisfies: 3.2mm≤d≤4.5mm. For example, when the diameter of the free end face of the first light guide column 2 is less than 3.2mm, the diameter of the free end face of the first light guide column 2 is relatively small, which increases the processing difficulty and precision requirements of the first light guide column 2, and is not conducive to the mass production of the first light guide column 2. When the diameter of the free end face of the first light guide column 2 is greater than 4.5mm, the diameter of the free end face of the first light guide column 2 is relatively large, thereby increasing the volume of the first light guide column 2, increasing the amount of material of the first light guide column 2, and also increasing the space occupied by the first light guide column 2 on the body 1, reducing the space utilization rate of the body 1. Therefore, by setting the diameter d of the free end face of the first light guide column 2 to satisfy: 3.2mm≤d≤4.5mm, the size of the free end face of the first light guide column 2 is reasonably designed, which is beneficial to the processing of the first light guide column 2 and is also beneficial to the arrangement of multiple first light guide columns 2 on the main body 1, so that the space utilization of the main body 1 is more reasonable.

[0062] According to some optional embodiments of the present invention, the free end surface of the second light guide column 3 constitutes a part of the spherical surface of the sphere. Therefore, the free end surface of the second light guide column 3 has a uniform curvature, which is conducive to the light emitted by the second lamp bead 203 opposite to the second light guide column 3 to irradiate the second light guide column 3 from multiple angles, thereby facilitating the focusing of the second light guide column 3.

[0063] Furthermore, the radius of the sphere is R, where R satisfies: R ≥ 14.3 mm. For example, when the radius of the sphere is less than 14.3 mm, the curvature of the free end face of the second light guide column 3 is relatively large, and the angle of the light irradiated from the free end of the second light guide column 3 to the second light guide column 3 after refraction is not easy to be consistent with the angle of the light refracted by the first light guide column 2, which reduces the uniformity of the light irradiated by the light transmissive member 100. Therefore, by setting the radius R of the sphere to satisfy: R ≥ 14.3 mm, the radius of the sphere is reasonably set, so that the curvature of the free end face of the second light guide column 3 is reasonably set, so as to be more conducive to the light irradiating to the second light guide column 3, and the angle of the light refracted by the second light guide column 3 is also more reasonable, which is more conducive to the use of the light transmissive member 100.

[0064] According to some optional embodiments of the utility model, the light-transmitting member 100 is a transparent member or a translucent member. Therefore, by setting the light-transmitting member 100 as a transparent member or a translucent member, the color of the light irradiated by the light-transmitting member 100 remains unchanged, reducing the influence of the light-transmitting member 100 on the light of the light board 201, and also reducing the influence of the light-transmitting member 100 on the propagation of light passing through the light-transmitting member 100, thereby facilitating the normal use of the light-transmitting member 100.

[0065] According to the light board assembly 200 of the second embodiment of the utility model, refer to Figure 6 , including a light-transmitting member 100 for a beauty instrument 400 according to the first aspect embodiment described above.

[0066] According to the lamp panel assembly 200 of the embodiment of the present invention, by adopting the above-mentioned light-transmitting member 100, the light emitted from the lamp panel assembly 200 is more uniform and the light loss is lower, thereby improving the performance of the lamp panel assembly 200.

[0067] According to some embodiments of the present invention, Figure 6-Figure 8 The lamp board assembly 200 further includes a lamp board 201, which is located on one side of the thickness direction of the light-transmitting member 100. A first lamp bead 202 and a second lamp bead 203 are provided on the lamp board 201. The first lamp bead 202 and the first light guide column 2 of the lamp board assembly 200 are opposite to each other along the thickness direction of the lamp board 201. The second lamp bead 203 and the second light guide column 3 of the lamp board assembly 200 are opposite to each other along the thickness direction of the lamp board 201. The colors of light emitted by the first lamp bead 202 and the second lamp bead 203 are different.

[0068] For example, in Figure 7 In the example, a groove 11 is formed on the lower surface of the light-transmitting member 100, a lamp board 201 is located on the lower side of the light-transmitting member 100, and a plurality of first lamp beads 202 and a plurality of second lamp beads 203 are arranged on the upper surface of the lamp board 201. At least a portion of the lamp board 201 fits in the groove 11, which facilitates the first lamp beads 202 to be opposite to the first light guide column 2, and the second lamp beads 203 to be opposite to the second light guide column 3, which is also beneficial to the assembly of the lamp board 201 and the light-transmitting member 100, and the assembly efficiency is high. The light emitted by the first lamp bead 202 is irradiated onto the first light guide column 2 and then irradiated from the upper surface of the light-transmitting member 100, and the light emitted by the second lamp bead 203 is irradiated onto the second light guide column 3 and then irradiated from the upper surface of the light-transmitting member 100, so that the light emitted by the first lamp bead 202 and the second lamp bead 203 is irradiated onto the upper surface of the light-transmitting member 100, so as to facilitate the light emitted by the first lamp bead 202 and the second lamp bead 203 to irradiate the upper surface of the light-transmitting member 100. In addition, the colors of the light emitted by the first lamp bead 202 and the second lamp bead 203 are different, and the energies of the first lamp bead 202 and the second lamp bead 203 are different. Under the joint action of the first lamp bead 202 and the second lamp bead 203, the lamp board assembly 200 used for the electrode head 300 of the beauty instrument 400 has a better use effect, which is conducive to the normal use of the beauty instrument 400 and also improves the beauty effect of the beauty instrument 400. It should be noted that the colors of the light emitted by the first lamp bead 202 and the second lamp bead 203 can be set according to actual use to better meet practical applications.

[0069] According to some optional embodiments of the present invention, the light emitted by the first lamp bead 202 is red light, and the light emitted by the second lamp bead 203 is yellow light. For example, the first lamp bead 202 emitting red light is arranged opposite to the first light guide column 2, and the second lamp bead 203 emitting yellow light is arranged opposite to the second light guide column 3. In this way, the colors of the light emitted by the first lamp bead 202 and the second lamp bead 203 are different. Under the joint action of the red light and the yellow light, the beauty effect of the beauty instrument 400 can be better exerted, thereby improving the performance of the beauty instrument 400.

[0070] Alternatively, if Figure 8 As shown, a plurality of first lamp beads 202 and a plurality of second lamp beads 203 are disposed on the lamp board 201. Figure 8 In the example, four first lamp beads 202 are arranged on the lamp board 201 at intervals along the circumference of the lamp board 201, and the four first lamp beads 202 are respectively arranged near the center of the lamp board 201, and the four first lamp beads 202 are symmetrical on the lamp board 201 along the horizontal axis and the vertical axis of the lamp board 201. Twelve second lamp beads 203 are arranged on the lamp board 201, of which four second lamp beads 203 are arranged alternately with the four first lamp beads 202 along the circumference of the lamp board 201, and the other eight second lamp beads 203 are located on the outer peripheral side of the plurality of first lamp beads 202, and the plurality of second lamp beads 203 are symmetrical on the lamp board 201 along the horizontal axis and the vertical axis of the lamp board 201, and four second lamp beads 203 are arranged around each first lamp bead 202. With such an arrangement, the layout of the plurality of first lamp beads 202 and the plurality of second lamp beads 203 is reasonable, which is conducive to the beauty performance of the beauty instrument 400.

[0071] According to some embodiments of the present invention, Figure 7 , the minimum distance between the side surface of the first lamp bead 202 facing the first light guide column 2 and the free end surface of the first light guide column 2 is h1, where h1 satisfies: 0mm

[0072] For example, in Figure 7 ​In the example, the vertical distance between the upper surface of the first lamp bead 202 and the lower surface of the first light guide column 2 is h1. When the minimum distance h1 between the side surface of the first lamp bead 202 facing the first light guide column 2 and the free end surface of the first light guide column 2 is greater than 0.8mm, the gap between the first lamp bead 202 and the first light guide column 2 is large, thereby extending the propagation path of the light emitted by the first lamp bead 202 to the first light guide column 2, and the light is easy to diverge, which is not conducive to the focusing of the first light guide column 2. Therefore, by setting the minimum distance h1 between the side surface of the first lamp bead 202 facing the first light guide column 2 and the free end surface of the first light guide column 2 to meet: 0mm

[0073] For example, in Figure 7 In the example, the vertical distance between the upper surface of the second lamp bead 203 and the lower surface of the second light guide column 3 is h2. When the minimum distance h2 between the side surface of the second lamp bead 203 facing the second light guide column 3 and the free end surface of the second light guide column 3 is greater than 0.8 mm, the gap between the second lamp bead 203 and the second light guide column 3 is large, thereby extending the propagation path of the light emitted by the second lamp bead 203 to the second light guide column 3, and the light is easy to diverge, which is not conducive to the focusing of the second light guide column 3. Therefore, by setting the minimum distance h2 between the side surface of the second lamp bead 203 facing the second light guide column 3 and the free end surface of the second light guide column 3 to meet: 0mm<h2≤0.8mm, the distance between the second light guide column 3 and the second lamp bead 203 is reasonably set, which is conducive to the light emitted by the second lamp bead 203 to irradiate the second light guide column 3, thereby facilitating the light propagation inside the light board assembly 200. Moreover, the second light guide column 3 is not easy to squeeze the second lamp bead 203, which can reduce the damage of the second light guide column 3 to the second lamp bead 203, thereby extending the service life of the second lamp bead 203 and further extending the service life of the lamp board assembly 200.
