[0002] Existing decorative lights typically attach LED beads or light strips to the outer surface of a light guide plate, with the LED beads or light strips emitting light on the front of the light guide plate to display the lighting effect.
[0003] However, LED beads or light strips are inconvenient to fix on the outer surface of the light guide plate, making installation troublesome. Utility Model Content
[0004] This utility model proposes a decorative lamp to overcome the shortcomings of the prior art, thereby solving the technical problem that the lamp beads of the decorative lamp are not easy to fix on the light guide plate in the prior art.
[0005] To achieve the above technical objectives, this utility model proposes a decorative lamp, including a light guide plate and a plurality of lamp beads. The light guide plate is provided with a circumferentially extending blind groove, and the blind groove has an opening for inserting the lamp beads. The plurality of lamp beads are arranged at intervals and housed in the blind groove. Each lamp bead includes a base and a light-emitting part mounted on the base. The light-emitting part is disposed towards the inside of the light guide plate, so that the light emitted by the light-emitting part diffuses inward along the width direction of the light guide plate.
[0006] The decorative lamp proposed in this utility model simplifies the installation and fixing of the lamp beads on the light guide plate by setting blind slots in the circumferential direction of the light guide plate.

Simultaneously, by adjusting the density and cross-sectional parameters of the light guide ribs, the attenuation gradient along the light propagation path can be precisely controlled, resulting in a more uniform light output effect on the light guide plate. Furthermore, by setting multiple light guide ribs to extend in the same direction and spaced apart perpendicular to that direction, the scattered light can exhibit regular scattering, further optimizing the light output effect of the light guide plate.
[0021] Preferably, the concave-convex structure is a light-guiding protrusion, and a plurality of light-guiding protrusions are staggered on the first surface and / or the second surface.
[0022] By adopting the aforementioned technical solution, the refraction and scattering of light by the light guide plate are enhanced, which helps to improve the light output effect of the light guide plate and increase the decorative effect of the decorative light.

[0030] Example 1: like Figures 1 to 6 As shown in the embodiment of this utility model, a decorative lamp includes a light guide plate 100 and a plurality of lamp beads 200. The light guide plate 100 is provided with a circumferentially extending blind groove 110. The blind groove 110 has an opening for the lamp beads 200 to be inserted. The plurality of lamp beads 200 are arranged at intervals and housed in the blind groove 110. The lamp beads 200 include a base 210 and a light-emitting part 220 mounted on the base 210. The light-emitting part 220 is disposed toward the inside of the light guide plate 100, so that the light emitted by the light-emitting part 220 diffuses inward along the width direction of the light guide plate 100.
[0031] Among them, blind slot 110 refers to slot that does not penetrate light guide plate 100.
[0032] Several LED beads 200 can be mounted on the same LED strip or connected to each other via wires. The LED beads 200 are connected in parallel to the same power supply line, which provides power. The LED beads 200 are also connected in parallel to the same control line, which connects to a controller. The controller controls the brightness and color of the LED beads 200. A notch may be provided on one side of the blind slot 110 for the power supply line to extend, or the power supply line may extend from the opening of the blind slot 110.
[0033] The decorative lamp proposed in this utility model simplifies the installation and fixing of the lamp beads 200 on the light guide plate 100 by providing a blind groove 110 in the circumferential direction of the light guide plate 100.
[0034] In this embodiment, the lamp bead 200 is an LED lamp bead.
[0035] In some other embodiments, the LED 200 may also be of other types.
[0036] In this embodiment, the light guide plate 100 is made of a transparent material and needs to have good processing performance. The light guide plate 100 is preferably made of acrylic or PC material.
[0037] The blind groove 110 can be formed on the light guide plate 100 through post-processing, such as by milling; or it can be integrally formed with the light guide plate 100, for example, the light guide plate 100 is a thermoplastic material, and the blind groove 110 is integrally formed on the light guide plate 100 during the casting or injection molding process.
[0038] Example 2: Based on Example 1, such as Figures 1 to 3 As shown, in this embodiment, the light guide plate 100 includes a first surface 101 and a second surface 102 spaced apart in the thickness direction. The blind groove 110 extends through the first surface 101 and toward the second surface 102. An opening is formed on the first surface 101. The lamp bead 200 enters the blind groove 110 through the opening. The blind groove 110 includes a first groove wall 112 located on the outer side and a second groove wall 113 located on the inner side. The base 210 is disposed toward the first groove wall 112, and the light-emitting part 220 is disposed toward the second groove wall 113.
[0039] The thickness of the light guide plate 100 is greater than the diameter of the lamp bead 200, and the depth of the blind slot 110 is adapted to the diameter of the lamp bead 200.
[0040] The first groove wall 112 located on the outside refers to the groove wall on the side of the blind groove 110 closest to the outer side of the light guide plate 100. The second groove wall 113 is the groove wall on the other side of the blind groove 110.
[0041] The cross-section of the blind groove 110 can be rectangular or other shapes, such as semi-circular, arc, etc.
[0042] This configuration provides a way to set a blind groove 110 on the light guide plate 100.
[0043] Example 3: Unlike Example 2, as Figures 4 to 6 As shown, in this embodiment, the light guide plate 100 includes a third surface 103 extending in its circumferential direction, a blind groove 110 extending through the third surface 103 and toward the inner side of the light guide plate 100, an opening formed on the third surface 103, an LED bead 200 entering the blind groove 110 through the opening, and a light-emitting part 220 disposed toward the bottom of the blind groove 110.
[0044] It is understood that the third surface 103 is the side of the light guide plate 100 connected between the first surface 101 and the second surface 102.
[0045] The cross-section of the blind groove 110 can be rectangular or other shapes, such as semi-circular, arc, etc.
[0046] This configuration provides another way to set the blind slot 110 on the light guide plate 100.
[0047] Example 4: Based on embodiments one to three, such as Figures 1 to 6 As shown, in this embodiment, the opening is filled with insulating adhesive that seals the LED bead 200.
[0048] By filling the opening with insulating glue, the LED 200 can be better secured in the blind slot 110.
[0049] The insulating adhesive is preferably transparent, such as UV adhesive or epoxy resin adhesive.
[0050] Example 5: Unlike Embodiment 4, in this embodiment, a sealing plate is provided in the opening to enclose the LED bead 200.
[0051] By providing a sealing plate that encloses the LED bead 200 in the opening, the LED bead 200 can be better fixed in the blind slot 110.
[0052] The sealing plate is preferably made of a transparent material. It can be made of the same material as the light guide plate 100, or other materials. The sealing plate can snap into the blind slot 110, thus securing it to the opening of the blind slot 110. Alternatively, the sealing plate can be fixed to the light guide plate 100 with fasteners or glued to it.
[0053] Example 6: Based on Examples 1 to 5, such as Figure 1 , Figure 4As shown, in this embodiment, the blind slots 110 are connected end to end in the circumferential direction of the light guide plate 100 to form a ring.
[0054] This arrangement allows the LED beads 200 to surround the light guide plate 100 around its circumference, thus enabling the LED beads 200 to fully illuminate the light guide plate 100 and enhance its decorative effect.
[0055] Example 7: Based on Examples 1 to 6, such as Figure 1 , Figure 4 As shown, in this embodiment, the shape of the blind groove 110 is adapted to the outer contour shape of the light guide plate 100.
[0056] This design makes the appearance of the light guide plate 100 more harmonious and enhances its aesthetic appeal.
[0057] The shape of the light guide plate 100 is not limited; it can be a directional shape, a circle, a triangle, a Christmas tree shape, or other shapes.
[0058] Example 8: Based on Examples 1 to 7, such as Figures 1 to 6 As shown, in this embodiment, the light guide plate 100 includes a first surface 101 and a second surface 102 spaced apart in the thickness direction. The first surface 101 and / or the second surface 102 are provided with a plurality of concave and convex structures, which are spaced apart.
[0059] By providing a plurality of concave and convex structures on the first surface 101 and / or the second surface 102, the concave and convex structures are used to generate light refraction and reflection, so that the light guide plate 100 presents visual effects such as light refraction and diffusion, thereby enhancing the aesthetics of the decorative lamp. At the same time, the concave and convex structures can locally disrupt the total internal reflection condition of the light guide plate 100, reducing the total internal reflection of the light guide plate 100 on the first surface 101 and / or the second surface 102, further improving the light efficiency of the light guide plate 100. Moreover, the plurality of concave and convex structures are spaced apart in the direction of light diffusion, so that the light can diffuse step by step during propagation, making the light output effect of the light guide plate 100 more uniform.
[0060] In this preferred embodiment, such as Figures 1 to 6 As shown, the concave-convex structure is a light guide rib 120, and several light guide ribs 120 extend along the same direction and are spaced apart perpendicular to that direction.
[0061] As light propagates within the light guide plate 100, it is modulated by the surface geometry of each light guide rib 120 it passes through. The light guide rib 120 forces the light to refract or scatter, causing some light to exit the light guide plate 100 through refraction or scattering, while the remaining light continues to propagate to the next light guide rib 120. Simultaneously, because the scattering of light through the light guide rib 120 is multidirectional, setting multiple light guide ribs 120 to extend in the same direction and spaced perpendicularly to that direction allows the scattered light to exhibit a regular scattering pattern.
[0062] By using multiple light guide ribs 120 that extend in the same direction and are spaced apart, light can be scattered step by step during its propagation inside the light guide plate 100, thus optimizing the light output effect on the light guide plate 100. At the same time, by adjusting the density and cross-sectional parameters of the light guide ribs 120, the attenuation gradient on the light propagation path can be precisely controlled, making the light output effect on the light guide plate 100 more uniform. Furthermore, by setting the multiple light guide ribs 120 to extend in the same direction and be spaced apart perpendicular to that direction, the scattered light can exhibit regular scattering, thus optimizing the light output effect of the light guide plate 100.
[0063] In another preferred embodiment, such as Figure 3 , Figure 7 As shown, the concave-convex structure is a light-guiding protrusion 130, and several light-guiding protrusions 130 are staggered on the first surface 101 and / or the second surface 102.
[0064] When light propagates inside the light guide plate 100, it is modulated by the surface geometry of each light guide protrusion 130 it passes through. The light guide protrusion 130 forces the light to be refracted or scattered. The refracted or scattered light propagates in different directions of the light guide protrusion 130, thereby breaking the direction of light propagation and making the light emission from the light-emitting surface more random.
[0065] The above settings enhance the refraction and scattering of light by the light guide plate 100, which helps to improve the light output effect of the light guide plate 100 and increase the decorative effect of the decorative light.
[0066] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Those skilled in the art should understand that this utility model includes, but is not limited to, the content described in the accompanying drawings and the specific embodiments above. Any modifications that do not depart from the functional and structural principles of this utility model will be included within the scope of the claims.
