Abstract
Description
Technical Field
[0001] This utility model relates to the field of lighting technology, and in particular to decorative lights. Background Technology
[0002] Existing decorative lights use LED beads that emit light through refraction and scattering via a light guide plate, which diffuses the light and creates a lighting effect on the light-emitting surface of the light guide plate. However, traditional decorative lights use flat light guide plates, which result in a relatively monotonous light output and poor decorative effect. Utility Model Content
[0003] This utility model proposes a decorative lamp to overcome the shortcomings of the prior art, thereby solving the problems of monotonous light output and poor decorative effect of the existing decorative lamps.
[0004] To achieve the above technical objectives, the decorative lamp proposed in this utility model includes a first light guide plate, a second light guide plate, and a plurality of lamp beads. The lamp beads are sandwiched between the first light guide plate and the second light guide plate. The first light guide plate and the second light guide plate are light-transmitting. The first light guide plate has a first light-incoming surface close to the lamp beads and a first light-outcoming surface away from the lamp beads. The first light-incoming surface and / or the first light-outcoming surface are provided with a plurality of refractive surfaces for changing the direction of light propagation. The first light guide plate is integrally formed by casting or injection molding to integrally form a plurality of refractive surfaces. The plurality of refractive surfaces are unevenly distributed on the first light-incoming surface and / or the first light-outcoming surface.
[0005] The decorative lamp of this utility model has a plurality of refracting surfaces on the first light-inlet surface and / or the first light-outlet surface, so that the light emitted by the lamp beads can be refracted by the refracting surfaces when entering and / or exiting the first light guide plate, thereby changing the light output effect of the first light guide plate and thus changing and improving the decorative effect of the decorative lamp.
[0006] Preferably, the second light guide plate has a second light-inlet surface close to the lamp bead and a second light-outlet surface away from the lamp bead. The second light-inlet surface and / or the second light-outlet surface are provided with a plurality of refractive surfaces for changing the direction of light propagation. The second light guide plate is integrally formed by casting or injection molding to integrally form a plurality of refractive surfaces. The plurality of refractive surfaces are distributed unevenly on the second light-inlet surface and / or the second light-outlet surface.
[0007] By adopting the aforementioned technical solution, since the second light guide plate is designed to be transparent, the light emitted by the lamp beads can be refracted by the refractive surface when entering and / or exiting the second light guide plate. On the one hand, this can change the light output effect of the second light guide plate and the decorative effect of the decorative lamp; on the other hand, it can enable the decorative lamp to emit light from both sides, further improving the decorative effect of the decorative lamp.
[0008] Preferably, the convex and concave distributions of the refractive surfaces of the first light guide plate and the second light guide plate are inconsistent at at least one lamp bead position.
[0009] By employing the aforementioned technical solution, the unevenness of the refracting surfaces of the first light guide plate and the second light guide plate at at least one position allows the decorative lamp to exhibit different luminous effects on the first light guide plate and the second light guide plate, which helps to improve the decorative effect of the decorative lamp.
[0010] Preferably, the first light-incoming surface and the second light-incoming surface are planar, and the first light-outcoming surface and the second light-outcoming surface are provided with refractive surfaces.
[0011] The aforementioned technical solution helps to control the parallelism of the first light guide plate and the second light guide plate during the assembly of decorative lights, thereby improving the yield rate of decorative light assembly.
[0012] Preferably, the first light-incoming surface or the second light-incoming surface is provided with a plurality of positioning posts, and a slot for positioning the lamp beads is formed between adjacent positioning posts. The first light guide plate and the second light guide plate are supported and assembled by the plurality of positioning posts.
[0013] By adopting the aforementioned technical solution, by providing a number of positioning posts on the first light-inlet surface or the second light-inlet surface, it is convenient to position and install a number of lamp beads on the first light guide plate or the second light guide plate, and it is also convenient to maintain an appropriate assembly gap between the first light guide plate and the second light guide plate during the assembly process.
[0014] Preferably, the first light guide plate and the second light guide plate are fixedly connected by clips or glue.
[0015] By adopting the aforementioned technical solution, the reliability and stability of the connection between the first light guide plate and the second light guide plate are improved, thereby enhancing the structural stability of the decorative lamp.
[0016] Preferably, the first light guide plate and the second light guide plate have the same shape and size.
[0017] By adopting the aforementioned technical solution, on the one hand, light leakage between the first light guide plate and the second light guide plate can be reduced; on the other hand, it also makes the decorative light more aesthetically pleasing.
[0018] Preferably, the geometry formed by connecting multiple LED beads is the same as the geometry of the outer contour of the first light guide plate.
[0019] By adopting the aforementioned technical solution, multiple LED beads can be distributed relatively evenly on the first light guide plate of the decorative lamp, thereby making the light output of the first light guide plate more uniform and improving the decorative effect of the decorative lamp.

[0032] like Figure 1 , Figure 2 As shown in the embodiment of this utility model, the decorative lamp includes a first light guide plate 100, a second light guide plate 200, and a plurality of lamp beads 300, which are sandwiched between the first light guide plate 100 and the second light guide plate 200. The first light guide plate 100 and the second light guide plate 200 are light-transmitting. The first light guide plate 100 has a first light-incoming surface 110 close to the lamp beads 300 and a first light-outcoming surface 120 away from the lamp beads 300. The second light guide plate has a second light-incoming surface 210 close to the lamp beads and a second light-outcoming surface 220 away from the lamp beads, so that the decorative lamp presents a decorative effect of light emanating from two sides.
[0033] The first light-emitting surface 120 is provided with a plurality of refractive surfaces 101 for changing the direction of light propagation. The first light guide plate 100 is integrally formed by casting or injection molding to form a plurality of refractive surfaces 101. The plurality of refractive surfaces 101 are distributed unevenly on the first light-emitting surface 120.
[0034] In some other embodiments, the first light-inlet surface 110 may be provided with a plurality of refractive surfaces 101, or both the first light-inlet surface 110 and the first light-outlet surface 120 may be provided with a plurality of refractive surfaces 101.
[0035] The uneven structure formed by the plurality of refractive surfaces 101 does not refer to the unevenness of the microstructure. In this embodiment, the unevenness height of the uneven structure formed by the plurality of refractive surfaces 101 is in the range of 1mm to 10mm, thereby blurring the light of the LED beads and expanding the illuminated area of the LED beads, making the light of the LED beads present an irregular light emission effect, thereby improving the decorative effect of the decorative lamp.
[0036] In this embodiment, the first light guide plate 100 is made of transparent plastic material, such as acrylic, transparent ABS, PC, etc.
[0037] In this embodiment, multiple LED beads 300 are connected in series and / or in parallel via a power cord 310. The power cord 310 is sandwiched between the first light guide plate 100 and the second light guide plate 200, and extends from one side between the first light guide plate 100 and the second light guide plate 200 to provide power to the LED beads 300.
[0038] Multiple LED beads 300 can be fixed to the first light guide plate 100 or the second light guide plate 200 with transparent glue, and the power cord 310 can also be fixed to the first light guide plate 100 or the second light guide plate 200 with glue.
[0039] The decorative lamp of this utility model has a plurality of refractive surfaces 101 provided on the first light-inlet surface 110 and / or the first light-outlet surface 120, so that the light emitted by the lamp bead 300 can be refracted by the refractive surfaces 101 when it enters the first light guide plate 100 and / or exits the first light guide plate 100, thereby changing the light output effect of the first light guide plate 100 and thus changing the decorative effect of the decorative lamp.
[0040] In one embodiment, the second light-gathering surface 210 is provided with a plurality of positioning posts 201, and slots for positioning lamp beads are formed between adjacent positioning posts 201. A plurality of lamp beads 300 are positioned in different slots, thereby arranging the plurality of lamp beads 300 on the second light guide plate 200 in a predetermined shape. When assembling the decorative light, the second light guide plate 200 is placed flat on a plane or tooling, the plurality of lamp beads 300 are positioned on the second light guide plate 200, and then the first light guide plate 100 is placed on the second light guide plate 200. The first light guide plate 100 is supported by the plurality of positioning posts 300 and maintains an appropriate assembly gap with the second light guide plate 200. Then the first light guide plate 100 and the second light guide plate 200 are fixedly connected to complete the assembly.
[0041] In some other embodiments, a plurality of positioning posts 201 may be provided on the first light-gathering surface 110.
[0042] The power cord 310 can also be positioned or fixed by the positioning post 201 or the slot.
[0043] By providing a plurality of positioning posts 201 on the first light-inlet surface 110 or the second light-inlet surface 210, it is convenient to position and install a plurality of lamp beads 300 on the first light guide plate 100 or the second light guide plate 200, and it is also convenient to maintain an appropriate assembly gap between the first light guide plate 100 and the second light guide plate 200 during the assembly process.
[0044] In one embodiment, the first light guide plate 100 and the second light guide plate 200 are fixedly connected by snap-fit fasteners. Specifically, the first light guide plate 100 and the second light guide plate 200 are clamped together by snap-fit fasteners, thereby fixing one end of the first light guide plate 100 and the second light guide plate 200. Multiple sets of snap-fit fasteners are used to fix the first light guide plate 100 and the second light guide plate 200 together.
[0045] In another embodiment, the first light guide plate 100 and the second light guide plate 200 are fixedly connected by adhesive.
[0046] The power cord 310 is secured by one of the sets of clips, or by glue to the first light guide plate 100 and / or the second light guide plate 200, thereby preventing the lamp bead 300 from shifting due to the pulling of the power cord 310.
[0047] The above-mentioned configuration improves the reliability and stability of the connection between the first light guide plate 100 and the second light guide plate 200, thereby enhancing the structural stability of the decorative lamp.
[0048] In one embodiment, such as Figure 1 , Figure 2 As shown, the first light guide plate 100 and the second light guide plate 200 have the same shape and size.
[0049] In this embodiment, the outer contours of the first light guide plate 100 and the second light guide plate 200 are both rectangular and of the same size. In other embodiments, the first light guide plate 100 and the second light guide plate 200 may also be of other geometric shapes, such as triangles, pentagons, circles, etc., and both shall be of the same size.
[0050] The above settings reduce light leakage between the first light guide plate 100 and the second light guide plate 200, and also make the decorative lights more aesthetically pleasing.
[0051] In one embodiment, such as Figure 1 , Figure 3 As shown, the geometry formed by connecting multiple LED beads 300 is the same as the geometry of the outer contour of the first light guide plate 100.
[0052] Because multiple LED beads 300 are connected by LED strips or wires, and the LED strips or wires are made of soft materials, the connection of multiple LED beads 300 cannot form a regular and accurate geometric shape. Here, the statement that the geometric shape formed by the connection of multiple LED beads 300 is the same as the geometric shape of the outer contour of the first light guide plate 100 means that the two form the same type of geometric shape.
[0053] In this embodiment, the first light guide plate 100 has a rectangular outline, and multiple LED beads 300 are connected to form a roughly rectangular shape; both are rectangular.
[0054] In some other embodiments, the first light guide plate 100 is triangular, pentagonal, or circular, and the geometry formed by connecting multiple LED beads 300 is also roughly triangular, pentagonal, or circular. See details for further information. Figure 3 The outer contour of the first light guide plate 100 is pentagonal, and multiple LED beads 300 are connected to form a roughly pentagonal shape.
[0055] With the above settings, multiple LED beads 300 can be distributed relatively evenly on the first light guide plate 100 of the decorative light, thereby making the light output of the first light guide plate 100 more uniform and improving the decorative effect of the decorative light.
[0056] To further improve the light output of decorative lights, such as Figure 2 As shown, in one embodiment, the second light-emitting surface 200 is provided with a plurality of refractive surfaces 101 for changing the direction of light propagation. The second light guide plate 200 is integrally formed by casting or injection molding to integrally form a plurality of refractive surfaces 101. The plurality of refractive surfaces 101 are distributed unevenly on the second light-emitting surface 220.
[0057] In some other embodiments, the second light-inlet surface 210 may be provided with a plurality of refractive surfaces 101, or both the second light-inlet surface 210 and the second light-outlet surface 220 may be provided with a plurality of refractive surfaces 101.
[0058] In another embodiment, the second light-emitting surface 220 is provided with a textured surface.
[0059] In this embodiment, the second light guide plate 200 is made of transparent plastic material, such as acrylic, transparent ABS, PC, etc.
[0060] With the above configuration, the second light-inlet surface 210 and / or the second light-outlet surface 220 are provided with a plurality of refractive surfaces 101 for changing the direction of light propagation, so that the light emitted by the lamp bead 300 can be refracted by the refractive surfaces 101 when entering the second light guide plate 200 and / or exiting the second light guide plate 200. On the one hand, it can change the light output effect of the second light guide plate 200 and change the decorative effect of the decorative lamp; on the other hand, it can enable the decorative lamp to emit light from both sides, further improving the decorative effect of the decorative lamp.
[0061] In one embodiment, such as Figure 2 As shown, the uneven distribution of the refracting surface 101 of the first light guide plate 100 and the second light guide plate at least one lamp bead 300 position is inconsistent.
[0062] By making the refracting surfaces 101 of the first light guide plate 100 and the second light guide plate at at least one position inconsistent, the decorative lamp presents different light emission effects on the first light guide plate 100 and the second light guide plate, which helps to improve the decorative effect of the decorative lamp.
[0063] To facilitate the positioning and installation of the first light guide plate 100, the second light guide plate, and the LED beads 300, in one embodiment, such as Figure 1 , Figure 2 As shown, the first light-inlet surface 110 and the second light-inlet surface 210 are planar, and the first light-outlet surface 120 and the second light-outlet surface 220 are provided with a refractive surface 101.
[0064] The LED beads 300 are first installed on the first light guide plate 100 or the second light guide plate. After the LED beads 300 are installed, the first light guide plate 100 and the second light guide plate are connected. Taking the installation of LED beads 300 on the second light guide plate as an example, the second light guide plate is placed flat on a plane or tooling, and multiple LED beads 300 are placed on the second light-incoming surface 210 and fixed with glue. After fixing, the multiple LED beads 300 are basically at the same horizontal height. Then, the first light guide plate 100 is placed on the second light guide plate. The first light-incoming surface 110 is flat, which helps the first light guide plate 100 placed on the LED beads 300 to be parallel to the second light guide plate. The first light guide plate 100 and the second light guide plate are fixedly connected by clips or glue, completing the assembly of the decorative light.
[0065] The above settings help control the parallelism of the first light guide plate 100 and the second light guide plate 200 during decorative light assembly, thereby improving the yield rate of decorative light assembly.
[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.
