Abstract
Description
Technical Field
[0001] This invention relates to the field of light strip lighting technology, and in particular to a modular light guide backplate structure. Background Technology
[0002] With the rapid development of display technology and the lighting industry, light guide plates and LED strips, as core components of backlight modules, directly affect the product's display effect, energy consumption, and manufacturing cost through their structural design and assembly processes. However, traditional light guide plates typically use an integrated metal frame and LED strip mounting method, which has the following technical limitations:
[0003] 1. Low assembly precision: LED light strips are directly fixed to the light guide plate by means of thermally conductive adhesive, etc. Manual assembly is prone to positional deviation, which leads to uneven gap between the light strip and the light guide plate on the light-incident side, causing local uneven brightness or light spot problems.
[0004] 2. High maintenance costs; When LED light strips experience light source attenuation or need to be replaced with light strips of different wattages, the entire structure needs to be replaced because the light strips are directly fixed to the light guide plate, resulting in high maintenance costs.
[0005] 3. Poor structural scalability; because the use of an integral metal frame in modular splicing scenarios, problems such as large splicing gaps and light leakage are particularly prominent.
[0006] To address the aforementioned issues, a modular light guide backplate structure could be proposed. This structure uses clips to hold the LED strips in place on the frame, allowing for easy and quick replacement of the strips simply by removing the clips. This significantly reduces maintenance costs. Furthermore, the light guide plate and frame work together to effectively control light leakage and improve the uniformity of the light surface. This design supports multi-module splicing and can flexibly adapt to display requirements of different sizes. Utility Model Content
[0007] To overcome the shortcomings of existing technologies, this utility model provides a modular light guide backplate structure. This structure uses clips to indirectly limit the LED light strips to the frame, which allows for quick disassembly and replacement of the light strips, significantly reducing maintenance costs. The frame is divided into two horizontal frames and one vertical frame. This combination method can also support multi-module splicing and flexibly adapt to different display size requirements.
[0008] The technical solution adopted by this utility model to solve its technical problem is:
[0009] This utility model provides a modular light guide backplate structure, which includes a light guide plate, at least one light strip, and at least one frame. The frame is provided with at least one slot. The light strip is first limited and fitted in the buckle, and the buckle is then limited and fitted in the slot on the frame. The slot of the frame is limited and fitted in the side of the light guide plate.
[0010] As described above, in a modular light guide backplane structure, a bracket is provided on the frame, and the bracket is respectively positioned and fitted at both ends of the frame.
[0011] As described above, in a modular light guide backplate structure, the frame is divided into a horizontal frame and a vertical frame. The horizontal frame is matched with the horizontal side of the light guide plate, and the vertical frame is matched with the vertical side of the light guide plate.
[0012] As described above, in a modular light guide backplate structure, the light guide plate is a rectangular flat plate, and the minimum distance between any one side of the light guide plate is one meter.
[0013] The modular light guide backplane structure described above has an aluminum frame.
[0014] In the modular light guide backplate structure described above, the light strip is an LED light strip, and the length of the light strip is not greater than the length of the frame.
[0015] As described above, in a modular light guide backplate structure, the buckle is a U-shaped buckle, and the bottom of the inner cavity of the U-shaped buckle is provided with a contour groove, which cooperates with the light strip.
[0016] As described above, in a modular light guide backplate structure, the buckle is a symmetrical design.
[0017] In the modular light guide backplate structure described above, the buckle is a flexible metal buckle or a flexible plastic buckle.
[0018] As described above, a modular light guide backplate structure includes a fixed base plate, a first guide protrusion, and a second guide protrusion. The fixed base plate is positioned and fitted on the horizontal frame and / or the vertical frame. The first guide protrusion and the second guide protrusion are disposed on one side of the fixed base plate. The first guide protrusion is positioned and fitted with a slot in the vertical frame. The horizontal frame is provided with a guide slot that cooperates with the second guide protrusion.
[0019] The beneficial effects of this utility model are as follows: the frame provides support and limitation for the buckle through the slot, and the buckle provides support and limitation for the light strip. The buckle ensures the precise position of the light strip and avoids deviations that may occur during direct installation. The buckle provides a certain margin of error and ensures the stability of the light strip. The light guide plate cooperates with the slots of several frames. This cooperation method not only effectively controls light leakage and improves the uniformity of the light output surface, but also simplifies the installation process and reduces material usage. It is further adapted to modular design, allowing for splicing of different sizes and facilitating maintenance or replacement. The rectangular flat plate of the light guide plate can better transmit light, and the use of a rectangular flat plate allows multiple light guide plates to be spliced together to form light guide plate back plates of different sizes, which can meet the needs of most commercial and industrial lighting scenarios.

[0028] 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.
[0029] like Figure 1 and Figure 6 As shown, in this embodiment, the present invention includes a light guide plate 1, at least one light strip 2, and at least one frame 3. The frame 3 has at least one slot. The light strip 2 is first positioned within a buckle 5, and the buckle 5 then engages with the slot on the frame 3. The slot on the frame 3 also engages with the side of the light guide plate 1. Thus, the frame 3 provides support and positioning for the buckle 5 through the slot, and the buckle 5 provides support and positioning for the light strip 2. The buckle 5 ensures the precise positioning of the light strip 2, avoiding deviations that may occur with direct installation. The buckle 5 provides a certain margin of error while ensuring the stability of the light strip 2. The light guide plate 1 engages with the slots of the frame 3. This engagement method not only effectively controls light leakage and improves the uniformity of the light output surface, but also simplifies the installation process, reduces material usage, further adapts to modular design, allows for splicing of different sizes, and facilitates maintenance or replacement.
[0030] Furthermore, in this embodiment, a bracket 4 is provided on the frame 3, and the bracket 4 is respectively positioned and engaged at both ends of the frame 3. Therefore, the frame 3 serves to limit the movement of the bracket 4, and the bracket 4, in contact with the ground, provides support for this invention.
[0031] Furthermore, in this embodiment, the frame 3 is divided into a horizontal frame and a vertical frame. The horizontal frame is matched with the horizontal side of the light guide plate 1, and the vertical frame is matched with the vertical side of the light guide plate 1. Therefore, this matching method not only effectively controls light leakage and improves the uniformity of the light-emitting surface, but also simplifies the installation process. Furthermore, the combined use of the vertical frames reduces material usage. Additionally, this matching method is compatible with modular splicing, further facilitating maintenance or replacement.
[0032] Furthermore, in this embodiment, the light guide plate 1 is a rectangular flat plate, and the shortest distance along any side of the light guide plate 1 is one meter. Therefore, the rectangular flat plate design of the light guide plate 1 allows for better light transmission, and the use of a rectangular flat plate enables multiple light guide plates 1 to be joined together to form light guide plate backplates of different sizes, meeting the needs of most commercial and industrial lighting scenarios. At the same time, the minimum length of the light guide plate 1 (not less than one meter) is a standard set considering overall cost.
[0033] Furthermore, in this embodiment, the frame 3 is an aluminum frame 3. Therefore, the frame material is aluminum, which ensures the overall structure remains stable while also providing strong heat dissipation performance. It can quickly conduct away the heat generated by the LED light strip 2, effectively reducing the operating temperature of the LED chip, extending its lifespan, and improving the overall luminous efficacy and stability of the lamp. At the same time, aluminum has strong corrosion resistance and weather resistance, maintaining its aesthetic appearance and stable performance even under harsh natural environments such as rain and sun exposure for a long time.
[0034] Furthermore, in this embodiment, the light strip 2 is an LED light strip, and the length of the light strip 2 is not greater than the length of the frame 3. It is evident that the length of the light strip 2 is not greater than the length of the frame 3 to avoid heat accumulation. LED light strips generate heat during operation; if the light strip length exceeds the frame, the excess portion cannot be effectively covered and dissipated by the frame, leading to localized overheating, accelerating LED chip light decay, or even damage. This ensures uniform heat dissipation and also prevents the light strip 2 from deforming. LED light strips are made of flexible material; if they exceed the frame length, they are prone to bending and sagging during installation or use, causing changes in the spacing between LED beads and affecting the uniformity of light efficiency.
[0035] Furthermore, in this embodiment, the buckle 5 is a U-shaped buckle, and the bottom of the inner cavity of the U-shaped buckle is provided with a contoured groove, which cooperates with the light strip 2. Thus, the buckle 5 provides support and fixation for the groove and the contoured groove; the groove guides and limits the wiring of the light strip 2; and the contoured groove limits the position of the light strip 2.
[0036] Furthermore, in this embodiment, the buckle 3 is symmetrically designed. This is advantageous for the design of the buckle 3 and mold development.
[0037] Furthermore, in this embodiment, the buckle 3 is an elastic metal buckle or an elastic plastic buckle. Therefore, the buckle 3 is an elastic buckle, and its deformation characteristics can absorb assembly tolerances, ensuring optical coupling consistency, thereby reducing light leakage and improving the uniformity of the light-emitting surface.
[0038] Furthermore, in this embodiment, the bracket 4 includes a fixed base plate 40, a first guide protrusion 41, and a second guide protrusion 42. The fixed base plate 40 is fitted into the horizontal frame and / or the vertical frame. The first guide protrusion 41 and the second guide protrusion 42 are disposed on one side of the fixed base plate 40. The first guide protrusion 41 is fitted into the slot of the vertical frame, and the horizontal frame is provided with a guide slot that mates with the second guide protrusion 42. Thus, the fixed base plate 40 provides support and fixation for the first guide protrusion 41 and the second guide protrusion 42. The first guide protrusion 41, fitted into the slot of the vertical frame, provides guidance and horizontal positioning. The second guide protrusion 42, fitted into the slot of the horizontal frame, provides guidance and vertical positioning, making the installation of the bracket 4 simpler and smoother.
[0039] The working principle of this utility model is as follows:
[0040] The light strip 2 is first positioned and fitted on the contour groove of the buckle 5. The wire of the light strip 2 is positioned and fitted through the groove. The buckle 5 is positioned and fitted inside the frame 3. The frame 3 is positioned and fitted with the side of the light guide plate 1. A pair of brackets 4 are respectively set on the frame 3.
[0041] It should be understood that the terms "first," "second," etc., are used in this utility model to describe various information, but this information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this utility model, "first" information can also be referred to as "second" information, and similarly, "second" information can also be referred to as "first" information. In addition, the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0042] The above embodiments do not limit the scope of protection of this utility model. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this utility model shall still fall within the scope of this utility model.
