Description

Technical Field

[0001] This utility model relates to the field of COB flexible light strip technology, and in particular to a COB flexible light strip that can emit light from the side. Background Technology

[0002] Side-emitting COB flexible light strips are mainly used for creative lighting and atmosphere creation in various spaces. Through a unique side-emitting chip arrangement design, a high-brightness and uniform light emission optical structure, and a flexible substrate with excellent flexibility, combined with high-efficiency and energy-saving LED chips and bend-resistant materials, they can achieve multi-angle, soft and layered light output in scenarios such as indoor decorative lighting, commercial window displays, automotive interior lighting, and electronic product backlighting. They are suitable for lighting decoration scenarios with complex shapes such as arcs and irregular shapes.

[0003] The side-emitting COB flexible light strip mainly consists of a side-emitting LED chip array, a highly flexible substrate, and an optical-grade diffusion layer. Its working principle is that the side-emitting LED chips are closely arranged on the highly flexible substrate, and the chips are directly soldered to the substrate through flip-chip technology, which reduces light decay and improves luminous efficiency. The optical-grade diffusion layer covers the chip surface, evenly disperses the light, and avoids the appearance of light spots. This allows the light strip to achieve a stable and uniform side-emitting effect in a variety of complex environments, meeting diverse lighting needs.

[0004] Traditional side-emitting COB flexible light strips have limitations such as narrow illumination range and low light utilization. In practical applications, a large amount of their scattered light is absorbed by the mounting surface, resulting in severe light loss. Furthermore, they cannot achieve flexible changes in illumination angle and range through physical structural adjustments, leading to a disconnect between lighting functions and diverse scene requirements. They cannot meet the personalized lighting needs in different scenarios. Therefore, a side-emitting COB flexible light strip is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a side-emitting COB flexible light strip, which aims to improve the limitations of the existing technology, such as narrow illumination range and low light utilization, and the inability to meet the personalized lighting needs in different scenarios.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A side-emitting COB flexible light strip includes a housing, a sliding column slidably connected inside the housing, a limit block slidably connected to the bottom end of the sliding column, a reflector fixedly connected to the bottom end of the limit block, a limit post fixedly connected inside the sliding column, a fixed post rotatably connected inside the housing, a rotating rod fixedly connected to the rear end of the fixed post, a rotating shaft fixedly connected to the rear end of the rotating rod, a driven rod rotatably connected to the bottom end of the rotating shaft, and a splicing assembly provided at the rear end of the housing.

[0008] As a further description of the above technical solution:

[0009] The splicing assembly includes a docking block, the rear end of which is fixedly connected to the front end of the housing. A connecting block is slidably connected inside the docking block, and a second fixing column is fixedly connected inside the connecting block. A telescopic column is fixedly connected to the left end of the second fixing column, and a sliding block is fixedly connected to the front end of the telescopic column. A spring is sleeved on the outside of the telescopic column.

[0010] As a further description of the above technical solution:

[0011] A control block is fixedly connected to the top of the sliding column, and a control handle is fixedly connected to the left end of the reflector.

[0012] As a further description of the above technical solution:

[0013] The housing has a limiting groove inside, and the limiting post is slidably connected to the inside of the limiting groove.

[0014] As a further description of the above technical solution:

[0015] A light is fixedly connected inside the housing, and the left end of the driven rod is fixedly connected to the right end of the reflector;

[0016] As a further description of the above technical solution:

[0017] One end of the spring is fixedly connected to the left end of the second fixed post, and the other end of the spring is fixedly connected to the right end of the sliding block.

[0018] As a further description of the above technical solution:

[0019] The docking block has a groove inside, and the outside of the sliding block is slidably connected to the inside of the groove;

[0020] As a further description of the above technical solution:

[0021] The outer side of the sliding block is oblique, and the outer side of the reflector is slidably connected to the inside of the housing.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, dragging the control block causes the sliding column to slide out of the limit block to release the restriction. Then, pushing and pulling the control handle allows the reflector to slide out of the housing. During this process, the driven rod drives the rotating shaft to rotate, and the rotating shaft drives the rotating rod to move, so that the reflector can only slide to a designated position outside the housing, thereby reflecting and refracting the scattered light from the light source, reducing the loss absorbed by the mounting surface, and expanding the illumination range. When a large-area illumination is not required, pushing and pulling the reflector causes it to slide into the housing, and pressing the control block causes the sliding column to slide into the limit block, which restricts the position of the limit block, allowing the operator to adaptively select the illumination range according to different scenarios and lighting requirements.

[0024] 2. In this utility model, pressing the sliding block causes the telescopic column to move to the right and compress the spring. After the connecting block is dragged to the designated position inside the docking block, the compressed spring will push the sliding block to slide out of the groove of the docking block, thereby restricting the position of the docking block on the connecting block and achieving rapid splicing. When disassembly is required, pressing the sliding block causes it to slide out of the groove to release the restriction, and dragging the docking block to completely detach it from the connecting block allows for rapid disassembly. This enables the operator to adaptively select the enhancement or reduction of the light extension degree according to different scenarios such as large shopping malls and display stands.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figures 1 to 3 This utility model provides an embodiment of a side-emitting COB flexible light strip, including a housing 1. The housing 1 provides a stable operating environment for the internal components. A sliding column 2 is slidably connected inside the housing 1. The sliding column 2 can drive the subsequent components to move stably by sliding inside the housing 1. A limit block 3 is slidably connected to the bottom end of the sliding column 2. Through the sliding connection between the limit block 3 and the sliding column 2, the position of both can be accurately controlled to ensure the stability of the structure. A reflector 4 is fixedly connected to the bottom end of the limit block 3. The reflector 4 can reflect light and improve the light utilization rate. A limit column 5 is fixedly connected inside the sliding column 2. The limit column 5 is fixedly connected to the sliding column 2 to provide guidance and limit for the movement of the sliding column 2 and prevent it from deviating during the movement.

[0035] Reference Figure 1 , Figure 2 and Figure 4The housing 1 has a fixed column 7 inside, which provides fixed support for the subsequent transmission structure. A rotating rod 8 is fixedly connected to the rear end of the fixed column 7, and a rotating shaft 9 is fixedly connected to the rear end of the rotating rod 8. This fixed connection between the rotating shaft 9 and the rotating rod 8 ensures stable power transmission during rotation. A driven rod 10 is rotatably connected to the bottom end of the rotating shaft 9. This rotatable connection between the driven rod 10 and the rotating shaft 9 allows the driven rod 10 to move with the rotation of the rotating shaft 9, thus transmitting power. The rear end of the housing 1 is equipped with a splicing assembly. To enable rapid assembly and disassembly, a control block 6 is fixedly connected to the top of the sliding column 2. The control block 6 can be used to control the movement of the sliding column 2. A control handle 11 is fixedly connected to the left end of the reflector 4. The position of the reflector 4 can be controlled by the control handle 11, which also provides power for the movement of the internal components of the housing 1. A limit groove is opened inside the housing 1. The limit groove provides an accurate path and limit range for the sliding of the limit column 5. The external sliding connection of the limit column 5 is inside the limit groove, which can ensure that the sliding column 2 remains stable during the sliding process and will not shake or deviate.

[0036] Inside the housing 1, a light lamp 18 is fixedly connected. The light lamp 18 is the light source of the flexible light strip, which can emit light and illuminate the designated area. The left end of the driven rod 10 is fixedly connected to the right end of the reflector 4. Through the fixed connection between the driven rod 10 and the reflector 4, the driven rod 10 can drive the reflector 4 to move accurately, thereby achieving effective control of the light.

[0037] Reference Figure 1 , Figure 5 and Figure 6 The splicing assembly includes a docking block 12, the rear end of which is fixedly connected to the front end of the housing 1 to ensure that it will not easily loosen during splicing and disassembly. A connecting block 13 is slidably connected inside the docking block 12. This slidable connection ensures smooth sliding of the connecting block 13, maintaining stability after splicing and preventing shaking. A second fixing column 14 is fixedly connected inside the connecting block 13, providing a stable foundation for components such as the telescopic column 15, ensuring no displacement during movement. A telescopic column is fixedly connected to the left end of the second fixing column 14. 15. The telescopic column 15 can flexibly extend and retract when subjected to external force. A sliding block 16 is fixedly connected to the front end of the telescopic column 15. The sliding block 16 is fixedly connected to the telescopic column 15 and can cooperate with the sliding groove inside the docking block 12. A spring 17 is sleeved on the outside of the telescopic column 15. The spring 17 can provide power for the movement of the sliding block 16. One end of the spring 17 is fixedly connected to the left end of the fixed column 14 and the other end is fixedly connected to the right end of the sliding block 16. Through the fixed connection with the fixed column 14 and the sliding block 16, the spring 17 can provide a stable force to the sliding block 16.

[0038] The docking block 12 has a groove inside, and the sliding block 16 is externally slidably connected to the inside of the groove. The groove and the sliding block 16 cooperate to provide an accurate track and range for the sliding block 16 to slide. The outside of the sliding block 16 is oblique. The oblique design makes it easy for the connecting block 13 to be smoothly inserted into the docking block 12, and at the same time provides reliable stability after splicing. The outside of the reflector 4 is externally slidably connected to the inside of the housing 1. The sliding connection between the reflector 4 and the housing 1 allows the operator to adaptively select the illumination range according to different usage scenarios and different illumination requirements.

[0039] Working principle: When the operator needs a wider range of illumination using the side-emitting COB flexible light strip, drag the control block 6 to make the sliding column 2 slide out of the limit block 3, thus removing the restriction of the sliding column 2 on the position of the limit block 3. Push and pull the control handle 11 to make the reflector 4 slide out of the housing 1. At the same time, during the sliding of the reflector 4, the driven rod 10 moves, driving the rotating shaft 9 to rotate. The rotation of the rotating shaft 9 drives the rotating rod 8 to move. Due to the presence of the driven rod 10 and the rotating rod 8, the reflector 4 can only slide out to a designated position outside the housing 1, realizing the reflection and refraction of the light scattered by the light lamp 18, avoiding the loss of light absorbed by the mounting surface. In addition, the illumination range can be expanded to a larger range. When a wider range of illumination is not needed, push and pull the reflector 4 to make the reflector 4 slide into the housing 1. Press the control block 6 to make the sliding column 2 slide into the limit block 3, thus restricting the position of the limit block 3. This allows the operator to adaptively select the illumination range according to different usage scenarios and different illumination requirements.

[0040] When the operator uses the side-emitting COB soft light, pressing the sliding block 16 causes the telescopic column 15 to move to the right and compress the spring 17. The connecting block 13 is then dragged to the designated position inside the docking block 12. The compressed spring 17 pushes the sliding block 16 in the opposite direction, causing the sliding block 16 to slide out of the groove inside the docking block 12. This restricts the position of the connecting block 13 by the docking block 12, achieving a quick splicing effect. When disassembly is required, pressing the sliding block 16 causes it to slide out of the groove inside the docking block 12, removing the restriction of the connecting block 13 by the docking block 12. The docking block 12 is then dragged to completely slide out of the connecting block 13, achieving a quick disassembly effect. This allows the operator to adaptively select to strengthen or weaken the light's extension according to different scenarios such as large shopping malls and display stands.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
