Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and more specifically, to a light strip and a display screen. Background Technology

[0002] The display screen includes multiple LED strips, each strip consisting of a housing and a cover. The cover allows the LED strips to operate stably under various environmental conditions while maintaining good visual performance.

[0003] In related technologies, the LED mask serves as a crucial component of the LED strip. On one hand, the mask effectively resists harsh external conditions such as wind, rain, dust, and ultraviolet radiation, protecting internal components like LED chips and circuit boards from damage and thus extending the overall lifespan of the screen. On the other hand, through proper design, the mask can also optimize display effects, reduce interference from ambient light on the LED chips, and improve the clarity and contrast of displayed content, thereby enhancing the overall display quality.

[0004] However, in order to reduce the impact on the LED strip during transportation, the face shield in related technologies usually consists of a face shield body and a protective cover connected to the face shield body. The protective cover may block some light, which will affect the display effect of the LED strip when viewed from certain angles, reduce the brightness of the LED strip, and result in a poor overall display effect of the screen. Utility Model Content

[0005] The main objective of this invention is to provide a light strip and a display screen to solve the problem in related technologies where the overall display effect of the display screen is poor due to the need to reduce the impact of light strips during transportation.

[0006] To achieve the above objectives, according to one aspect of the present invention, a light strip is provided, comprising: a light housing having a receiving cavity and an opening communicating with the receiving cavity, wherein a first snap-fit ​​structure is provided at the portion of the light housing having the opening; a display component including a light panel and LEDs disposed on the light panel, the light panel being disposed within the receiving cavity, and the LEDs being disposed corresponding to the opening; and an extruded mask covering the opening, the extruded mask including a mask body and a second snap-fit ​​structure disposed on the mask body, the second snap-fit ​​structure engaging with the first snap-fit ​​structure, the LEDs extending outwards from the mask body, and the portion of the extruded mask facing away from the receiving cavity protruding outwards from the surface of the LEDs facing away from the light panel, the extruded mask being an integrally formed structure.

[0007] Furthermore, the mask body is provided with machining holes, and the LED beads are inserted into the machining holes.

[0008] Furthermore, the second snap-fit ​​structure is a snap hook set on the edge of the mask body. The mask body is recessed relative to the surface of the snap hook away from the receiving cavity, and the surface of the snap hook away from the receiving cavity protrudes outward from the surface of the lamp bead away from the lamp board.

[0009] Furthermore, the hook includes a first hook and a second hook, which are respectively disposed on two opposite edges of the mask body; the second snap-fit ​​structure includes a first slot and a second slot, which are respectively disposed on two opposite outer walls of the lamp housing; the first hook engages with the first slot, and the second hook engages with the second slot.

[0010] Furthermore, the extruded face mask also includes a first inclined section connected between the first hook and the face mask body, and a second inclined section connected between the second hook and the face mask body, wherein the included angle between the first inclined section and the second inclined section is an obtuse angle.

[0011] Furthermore, the included angle A satisfies: 160°≤A<180°.

[0012] Furthermore, the thickness D of the extruded face mask satisfies: 0.5mm≤D≤1.0mm.

[0013] Furthermore, the display assembly also includes a waterproof layer disposed on the side of the lamp panel facing the lamp beads, the waterproof layer surrounding the outside of the lamp beads, and a waterproof layer height indicator structure disposed on the inner side wall of the lamp housing.

[0014] According to another aspect of the present invention, a display screen is provided, including a light strip, wherein the light strip is the aforementioned light strip.

[0015] Furthermore, there are multiple light strips, which are spaced apart along a preset direction.

[0016] The present invention relates to a light strip comprising a lamp housing, a display component, and an extruded cover. The lamp housing has a receiving cavity and an opening communicating with the receiving cavity. A first snap-fit ​​structure is provided at the portion of the lamp housing with the opening. The display component includes a lamp board and LEDs disposed on the lamp board. The lamp board is disposed within the receiving cavity, and the LEDs are correspondingly positioned with respect to the opening. The extruded cover covers the opening and includes a cover body and a second snap-fit ​​structure disposed on the cover body. The second snap-fit ​​structure engages with the first snap-fit ​​structure, allowing the LEDs to protrude beyond the cover body. The surface of the extruded cover facing away from the receiving cavity protrudes outward beyond the surface of the LEDs facing away from the lamp board. The extruded cover is a one-piece molded structure. Thus, by employing the extruded cover, external dust, rainwater, sand, and other debris can be effectively prevented from entering the light strip, thereby improving its service life. Because the surface of the extruded mask facing away from the receiving cavity protrudes beyond the surface of the LED beads facing away from the light panel, this surface can absorb impacts on the LED beads during transportation, thus protecting them and reducing wear and tear during transport or installation. Furthermore, since the LED beads protrude beyond the mask body, the extruded mask does not obstruct the light emitted by the beads, avoiding the problem of poor display performance due to light strip protection, and improving the overall display effect of the light strip and the display screen. Simultaneously, the extruded mask is a one-piece molded structure, making its processing more convenient and reducing processing costs. Therefore, the technical solution of this application effectively solves the problem in related technologies where reducing light strip impacts during transportation leads to poor overall display performance.

[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. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0029] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0030] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0031] In this embodiment, as Figures 1 to 5 As shown, applying the technical solution of this utility model, the light strip includes: a lamp housing 10, a display component 20, and an extruded cover 30. The lamp housing 10 has a receiving cavity 11 and an opening 12 communicating with the receiving cavity 11. A first snap-fit ​​structure 13 is provided at the portion of the lamp housing 10 where the opening 12 is formed. The display component 20 includes a lamp plate 21 and lamp beads 22 disposed on the lamp plate 21. The lamp plate 21 is disposed in the receiving cavity 11, and the lamp beads 22 are disposed correspondingly to the opening 12. The extruded cover 30 covers the opening 12. The extruded cover 30 includes a cover body 31 and a second snap-fit ​​structure 32 disposed on the cover body 31. The second snap-fit ​​structure 32 is snap-fitted with the first snap-fit ​​structure 13. The lamp beads 22 protrude out of the cover body 31, and the surface of the extruded cover 30 facing away from the receiving cavity 11 protrudes from the surface of the lamp beads 22 facing away from the lamp plate 21. The extruded cover 30 is an integrally formed structure.

[0032] In this way, by adopting the extruded cover 30, external dust, rainwater, sand, and other debris can be effectively prevented from entering the lamp strip, thus improving its service life. Since the surface of the extruded cover 30 facing away from the receiving cavity 11 protrudes beyond the surface of the lamp bead 22 facing away from the lamp board 21 (i.e., the apex of the cover is higher than the apex of the lamp bead 22), the surface of the extruded cover 30 facing away from the receiving cavity 11 can withstand impacts on the lamp bead 22 during transportation, thus protecting the lamp bead 22 and reducing bumps and wear during transport or installation. Furthermore, since the lamp bead 22 protrudes beyond the cover body 31, the extruded cover 30 does not obstruct the light emitted by the lamp bead 22, avoiding the problem of poor display effect due to protection, and improving the overall display effect of the lamp strip and the display screen. At the same time, the extruded cover 30 is a one-piece molded structure, making its processing more convenient and reducing processing costs. Therefore, the technical solution of this embodiment effectively solves the problem in related technologies where the overall display effect of the display screen is poor due to the need to reduce the impact of light strips during transportation.

[0033] like Figures 1 to 5 As shown, the mask body 31 is provided with machining holes 311, and the LED beads 22 pass through the machining holes 311. Providing machining holes 311 on the mask body 31 allows for further adjustment of the distance between two adjacent machining holes 311 after the extruded mask 30 is formed, based on the actual spacing of the LED beads 22. This enables the extruded mask 30 to adapt to different LED bead 22 spacings, avoiding the cumbersome process of redesigning the mold due to changes in the LED bead 22 spacing. This significantly reduces production costs and improves the adaptability and production efficiency of the LED strip.

[0034] In this embodiment, the extruded face mask 30 is manufactured using an extrusion process. After extrusion molding, machining holes 311 are machined onto the face mask 30. The machining holes 311 are machined by stamping or laser cutting. The extrusion process can significantly reduce the production cost of the face mask, and machining holes 311 machined by stamping or laser cutting facilitates the adjustment of the distance between two adjacent machining holes 311 according to the actual spacing of the LED beads 22, improving the adaptability and flexibility of the extruded face mask 30. When the machining holes 311 are machined by stamping, the stamping die can be compatible with various punch heads with different spacings. According to the required distance between two adjacent machining holes 311, the punch heads with the corresponding spacing are assembled on the stamping die to punch out the machining holes 311 with the corresponding spacing. Furthermore, since the extruded face mask 30 is manufactured using an extrusion process, the length of the extruded face mask 30 is easier to adjust, reducing processing costs. In related technologies, face masks are formed using injection molding, requiring the creation of corresponding molds for different models. Furthermore, mold costs increase dramatically as the face mask length increases. In contrast, the extruded face mask 30 in this embodiment is produced using extrusion molding, eliminating the need for multiple molds for different models. Moreover, as the length of the extruded face mask 30 increases, production costs can be better controlled. Additionally, the extruded face mask 30 can be cut to the required length.

[0035] It should be noted that "inner" refers to the interior of the light strip's outline, while "outer" refers to the exterior of the light strip's outline.

[0036] like Figures 1 to 3 as well as Figure 5 As shown, the second snap-fit ​​structure 32 is a hook disposed on the edge of the mask body 31. The mask body 31 is recessed relative to the surface of the hook away from the receiving cavity 11, and the surface of the hook away from the receiving cavity 11 protrudes outward from the surface of the lamp bead 22 away from the lamp plate 21. The hook design on the mask body 31 not only achieves a stable connection between the mask and the lamp housing 10, but also, the surface of the hook away from the receiving cavity 11 protrudes outward from the surface of the lamp bead 22. During the transportation and installation of the lamp strip, the hook can serve as an additional protective layer for the lamp bead 22, reducing the probability of the lamp bead 22 being subjected to collisions. No additional protective structure is required, making the overall structure more compact and easier to process and assemble.

[0037] like Figures 1 to 3 as well as Figure 5As shown, the latches include a first latch 321 and a second latch 322, which are respectively disposed on two opposite edges of the mask body 31; the second latching structure 32 includes a first latching groove 131 and a second latching groove 132, which are respectively disposed on two opposite outer walls of the lamp housing 10; the first latch 321 engages with the first latching groove 131, and the second latch 322 engages with the second latching groove 132. This configuration makes the connection between the extruded mask 30 and the lamp housing 10 more reliable, facilitates the assembly of the extruded mask 30 and the lamp housing 10, and also facilitates the processing and production of the extruded mask 30 and the lamp housing 10.

[0038] like Figures 1 to 3 as well as Figure 5 As shown, the extruded face mask 30 also includes a first inclined section 33 connecting the first hook 321 and the face mask body 31, and a second inclined section 34 connecting the second hook 322 and the face mask body 31. The included angle between the first inclined section 33 and the second inclined section 34 is an obtuse angle. By providing the first inclined section 33 and the second inclined section 34 between the hook and the face mask body 31, it is convenient to position the face mask body 31 on the side that is concave towards the receiving cavity 11 relative to the hook, and it is also convenient to position the first hook 321 and the second hook 322 on the surface that protrudes outward from the lamp bead 22 away from the lamp plate 21, thereby facilitating the processing of the extruded face mask 30. Furthermore, the obtuse angle formed between the first inclined section 33 and the second inclined section 34 reduces the obstruction of the extruded face mask 30 on the light emission of the lamp bead 22, improving the display effect of the light strip.

[0039] like Figures 1 to 3 as well as Figure 5 As shown, the included angle A satisfies: 160°≤A<180°. By specifically limiting the included angle A formed between the first inclined segment 33 and the second inclined segment 34, it can be ensured that the LED bead 22 can emit light without obstruction within this angle, further improving the display effect of the LED strip, so that the display screen can display a clear and bright picture at different viewing angles, thereby improving the overall display effect of the display screen.

[0040] Preferably, the included angle A is 160°, 163°, 165°, 167°, 170°, 173°, 175°, 177° or 179°.

[0041] like Figure 4 and Figure 5As shown, the first snap-fit ​​structure 13 is a slot provided on the outer wall of the lamp housing 10, with the hook engaging with the slot. The slot on the lamp housing 10 and the hook on the face mask work together to form a simple yet effective snap-fit ​​mechanism, ensuring a secure connection between the extruded face mask 30 and the lamp housing 10, preventing the face mask from loosening or falling off due to vibration during transportation or external forces during use. Furthermore, the hook and slot structure is simple and easy to manufacture.

[0042] In this embodiment, the slot includes a first slot 131 and a second slot 132. The first slot 131 penetrates the end face of the outer wall of the lamp housing 10, and the second slot 132 penetrates the end face of the outer wall of the lamp housing 10 to facilitate the extrusion molding of the extruded face mask 30.

[0043] like Figures 1 to 5 As shown, there are two slots and two hooks. The two slots are respectively located on two opposite outer walls of the lamp housing 10, and the two hooks are respectively located on two opposite edges of the mask body 31. The two slots and two hooks are arranged in a one-to-one correspondence. The two hooks located on the opposite edges of the mask body 31 facilitate the extrusion molding of the extruded mask 30, reducing the production cost of the extruded mask 30. The two slots located on the opposite outer walls of the lamp housing 10 facilitate the processing of the slots, further reducing the production cost of the lamp housing 10.

[0044] Furthermore, the thickness D of the extruded faceplate 30 satisfies: 0.5mm ≤ D ≤ 1.0mm. The thickness D of the extruded faceplate 30 is limited to between 0.5mm and 1.0mm. This thickness range not only ensures that the extruded faceplate 30 has sufficient strength to resist external damage, but also maintains its thin and light characteristics, which helps reduce weight, optimize the overall performance of the display screen, and lower material costs. Because the extruded faceplate 30 is formed using an extrusion process, its thickness can be relatively thin, facilitating the installation of other structures within the lamp housing 10, such as the waterproof layer 23 described below.

[0045] like Figure 5 As shown, the display assembly 20 also includes a waterproof layer 23 disposed on the side of the lamp panel 21 facing the lamp beads 22. The waterproof layer 23 surrounds the outside of the lamp beads 22, and a waterproof layer height indicator structure 14 is provided on the inner wall of the lamp housing 10. The waterproof layer 23 between the lamp panel 21 and the lamp beads 22 not only provides additional waterproof protection and ensures the dryness of the connection between the lamp beads 22 and the lamp panel 21, but also improves the safety and lifespan of the lamp strip. The waterproof layer height indicator structure 14 on the inner wall of the lamp housing 10 facilitates control of the glue filling height of the waterproof layer 23 during production, ensuring waterproof performance and avoiding unnecessary cost increases caused by excessive glue filling.

[0046] In this embodiment, the waterproof layer height indicator structure 14 is a groove provided on the inner sidewall of the lamp housing 10. In other embodiments, the waterproof layer height indicator structure 14 is a protrusion provided on the inner sidewall of the lamp housing 10.

[0047] In this embodiment, the lamp housing 10 has a notch at its end along its length, and the lamp strip also includes a cover 40 detachably disposed at the notch. A support protrusion is provided on the inner sidewall of the lamp housing 10, and the lamp plate 21 is disposed above the support protrusion.

[0048] According to another aspect of this utility model, a display screen is provided, including a light strip, wherein the light strip is the aforementioned light strip. Since the aforementioned light strip can solve the problem in related technologies where the overall display effect of the display screen is poor due to the need to reduce bumps and knocks during transportation, a display screen having this light strip can solve the same technical problem.

[0049] Furthermore, there are multiple light strips, which are spaced apart along a preset direction. By arranging multiple light strips at intervals along a preset direction, not only can a larger display screen be constructed, but also, through reasonable layout, the light distribution is more uniform, further improving the overall display effect.

[0050] In this embodiment, the display screen is preferably a grid screen. The extruded cover 30 ensures that the advertising image on the grid screen is clearly visible in outdoor environments, while protecting the grid screen from external factors. In this embodiment, the extruded cover 30 is made of high-strength material and has a matte surface (the extruded cover 30 is produced using raw materials with a matte finish or a layer of matte oil is sprayed onto the outer surface of the extruded cover 30). It not only protects the internal components of the lamp housing, but the matte surface also enhances the display effect and reduces the decrease in contrast of the lamp strip surface due to strong light.

[0051] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms 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, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0052] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0053] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.

[0054] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
