Description

Technical Field

[0001] This utility model relates to the field of neon tubes, and in particular to a neon tube with a double-layer light guide structure. Background Technology

[0002] With the development of technology, existing neon tubes are generally composed of LED lights to achieve their colorful effects. However, in actual use, it has been found that when the length of the light body is long, if the LED light cannot be centered, shadows will appear on the outer lampshade, affecting the user experience.

[0003] For example, Chinese patent 202322769739.6 uses a lamp panel body directly embedded in a transparent adhesive jacket, which results in localized visual unevenness, and its assembly structure is relatively complex. Utility Model Content

[0004] The main purpose of this invention is to propose a neon tube with a double-layer light guide structure, which aims to improve the existing neon tube structure, enabling it to support a longer length, be easy to install, and have a stable structure.

[0005] To achieve the above objectives, this utility model proposes a neon tube with a double-layer light guide structure, comprising:

[0006] The inner sleeve has a first positioning cavity on its inner wall for placing an LED light board, and at least two first support pieces distributed along its length on its outer wall.

[0007] The outer sleeve has a second positioning cavity on its inner wall, and a first support groove that mates with the first support piece on its inner wall. The inner sleeve is located inside the outer sleeve.

[0008] The lampshade has a third positioning cavity on its inner wall, and a plurality of second support pieces extend inward from the third positioning cavity. The ends of the second support pieces abut against the wall of the outer sleeve.

[0009] The first connector is located at one end of the lampshade;

[0010] The second connector has a wire hole and is located at the other end of the lampshade.

[0011] In practical designs, the inner and outer sleeves are semi-transparent or milky white, which diffuses the light from the LED panel, resulting in more uniform light distribution and softer light.

[0012] At the same time, the use of the first and second support plates can effectively improve the support between the LED light board, inner sleeve, outer sleeve and lampshade, and also ensure the coaxiality between the above structures, further ensuring that the overall light of the neon tube is softer and reducing the problem of dark areas.

[0013] The installation is also relatively simple. Attached Figure Description

[0032] like Figures 1 to 5 As shown, a neon tube with a double-layer light guide structure includes:

[0033] The inner sleeve 1 has a first positioning cavity on its inner wall, which is used to place the LED light board 5. The outer wall of the inner sleeve 1 has at least two first support pieces 11 distributed along its length.

[0034] The outer sleeve 2 has a second positioning cavity on its inner wall, and a first support groove 12 that cooperates with the first support piece 11 on its inner wall. The inner sleeve 1 is located inside the outer sleeve 2.

[0035] The lampshade has a third positioning cavity on its inner wall, and a plurality of second support pieces 21 extend inward from the third positioning cavity. The ends of the second support pieces 21 abut against the wall of the outer sleeve 2.

[0036] First connector 3, the first connector 3 is located at one end of the lampshade;

[0037] The second connector 4 is provided with a wire hole 40 and is located at the other end of the lampshade.

[0038] In the actual design, the inner sleeve 1 and the outer sleeve 2 are semi-transparent or milky white, which diffuses the light from the LED light panel 5, making the light distribution more uniform and the light softer.

[0039] Meanwhile, the use of the first support piece 11 and the second support piece 21 can effectively improve the support between the LED light panel 5, the inner sleeve 1, the outer sleeve 2 and the lampshade, and also ensure the coaxiality between the above structures, further ensuring that the overall light of the neon tube is softer and reducing the problem of dark areas.

[0040] The installation is also relatively simple.

[0041] Specifically, the inner sleeve 1, the outer sleeve 2, and the lampshade are made of rigid materials. Of course, in actual use, a structure made of some or all of soft materials can be adopted to achieve the predetermined curvature.

[0042] In this embodiment of the present invention, the inner wall of the first positioning cavity is provided with two oppositely arranged slots 50, and the two sides of the LED light board 5 are installed in the slots 50.

[0043] Specifically, the first positioning cavity is provided with an inwardly extending third support part 51, and the slot 50 is provided on the third support part 51. The inwardly extending third support part 51 can effectively improve the support and rigidity of the inner sleeve 1, and also facilitate the installation of the LED light board 5, which can be directly slidably installed in the slot 50.

[0044] In this embodiment of the utility model, the slot 50 and the first support piece 11 are at the same horizontal position, and the LED light board 5 includes a PCB board and LED beads 52 disposed on the upper and lower walls of the PCB board, thereby facilitating alignment and reducing alignment problems.

[0046] A first gap is provided between the inner sleeve 1 and the outer sleeve 2, and a second gap is provided between the outer wall of the outer sleeve 2 and the inner wall of the lampshade.

[0047] The length of the first spacing is greater than the length of the second spacing, which can effectively improve the uniformity of diffuse reflection and the uniformity of the colors presented by the lampshade.

[0048] It can be understood that when the inner and outer lamp covers are removed, the light emitted by the LED beads 52 is distributed in a dotted pattern. The specific spacing can be adjusted by setting the width of the first support plate 11 and the second support plate 21.

[0049] In this embodiment of the utility model, the inner sleeve 1 and the outer sleeve 2 are made of light guiding material, wherein the material is mainly used to diffuse reflection, thereby making the light evenly distributed.

[0050] Specifically, the inner wall of the lampshade is provided with a first internal thread 61.

[0051] The first connector 3 is provided with a first external thread 62 that mates with the first internal thread 61; the end of the first external thread 62 is provided with a first smooth portion;

[0054] The second connector 4 is provided with a second external thread 72 that mates with the second internal thread 71; the end of the second external thread 72 is provided with a second smooth portion;

[0055] A second positioning groove 73 is provided between the second smooth part and the inner wall of the lampshade. The second positioning groove 73 is used to lock the end of the outer sleeve 2.

[0056] The design of the first positioning groove 63 and the second positioning groove 73 can effectively ensure the concentricity of the inner sleeve 1, while avoiding the shadow surface of the outer sleeve 2 at the end, thus improving the overall lighting effect.

[0057] Specifically, the second connector 4 is provided with a wire passage hole 40, and a wire plug 8 can be detachably installed in the wire passage hole 40, allowing the cable to pass through.

[0058] The wire hole 40 is provided with a third internal thread 81, and the wire plug 8 is provided with a third external thread 82 that mates with the third internal thread 81, thereby achieving a sealing performance at the wire end.

[0059] In actual production, the first connector 3 and the second connector 4 can be fixed with sealing rings, sealant, or ultrasonic welding to achieve relative sealing.

[0060] Specifically, the first connector 3 and the second connector 4 extend into the inner wall of the lamp cover and are provided with ribs that abut against the outer wall of the outer sleeve 2. The ribs are raised from the inside to the outside of the assembly to achieve guidance and limiting, ensuring that the outer sleeve 2 is locked and avoiding gap movement.

[0061] The first connector 3 and the second connector 4 are made of transparent material, and the lampshade is made of transparent material. The walls of the first connector 3 and the second connector 4 are textured.

[0062] The inner sleeve 1 and the outer sleeve 2 are made of milky white material or other materials, thereby achieving the desired neon tube effect.

[0063] Of course, in specific embodiments, LED beads can also be used on three sides, such as in a triangular shape.

[0064] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
