Description

Technical Field

[0001] This utility model relates to the field of LED linear light technology, and in particular to an LED linear light with no dark area. Background Technology

[0002] LED linear lights offer advantages such as high efficiency and energy saving, controllable light color, and ease of achieving continuous linear lighting, leading to their widespread application in numerous fields, including building exterior decoration. These lights typically consist of a light panel containing LED chips, a light body (usually made of aluminum profile) housing the light panel, and a light-transmitting cover over the light-emitting surface. To effectively seal both ends of the light body, protect internal electrical components, and provide an installation structure, existing technologies generally employ end caps, which define the position of the light cover and seal the two ends of the linear light.

[0003] However, the end caps in existing technologies cause dark areas with reduced brightness at the light-emitting ends of LED linear lights. Furthermore, when two linear lights are spliced ​​end-to-end to create continuous lighting, a more pronounced dark area forms at the splicing point. This phenomenon primarily stems from the physical obstruction effect of the end caps themselves. Specifically, the end cap structure hinders light emission from its corresponding lampshade area, preventing the light emitted by the LED closest to the end cap from fully illuminating the end area of ​​the LED linear light, thus creating dark areas at both ends of a single linear light. When multiple LED linear lights are spliced ​​continuously, the dark areas at the ends of two adjacent LED linear lights overlap and converge near the splicing point, causing the dark areas in this area to superimpose and be significantly amplified, ultimately forming a noticeable dark band or spot that affects the continuity of lighting, severely impacting the final lighting quality and aesthetics.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a dark-area-free LED linear light, which aims to solve the technical problem of dark light areas at the ends of existing LED linear lights.

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

[0007] A type of LED linear light with no dark areas includes: a light body;

[0008] The light panel is located inside the light body, and LED beads are arranged at intervals along its length.

[0009] A lampshade is disposed inside the lamp body and located on the light-emitting side of the lamp panel. The end of the lampshade extends to the end of the lamp body, and the end of the lampshade is provided with a first recess.

[0010] Two first end caps are respectively located at both ends of the lamp body. The first end caps have a first notch on the side facing the lampshade, and on the vertical projection plane, the bottom of the first notch is lower than the bottom of the lampshade.

[0011] The second end cap is installed on the first end cap and abuts against the first recess.

[0012] Furthermore, the first end cover has two fins on the side wall near the lamp plate, and the fins are connected to the two side walls of the lamp body by the first screw; the first end cover has a support block on the side away from the first notch, and the support block abuts against the bottom of the lamp body.

[0013] Furthermore, the shape of the first end cap is adapted to the shape of the inner wall of the lamp body.

[0014] Furthermore, a second recess is provided on the first end cap, and the second end cap is installed on the first end cap.

[0015] Furthermore, the distance between the LED bead and the upper surface of the lamp cover is 1.2 to 1.4 times the distance between two adjacent LED beads.

[0016] Furthermore, the lamp body is filled with a potting layer, which covers the lamp panel; a first drainage hole is provided on the first end cover, and a second drainage hole is provided on the second end cover corresponding to the position of the first drainage hole.

[0017] Furthermore, the lamp panel has several second notches on both sides, which are used to allow the potting layer to penetrate into the gap between the lamp panel and the bottom surface of the lamp body.

[0018] Furthermore, the outer side of the first end cap is provided with a horizontally arranged water guide groove, which is flush with the end of the lamp body; the end of the water guide groove extends to the side wall of the lamp body, and the side wall of the lamp body is provided with a third notch corresponding to the position of the water guide groove.

[0019] Beneficial effects:

[0020] This invention provides a dark-spot-free LED linear light. By extending the lampshade end to the lamp body end and using a second end cap to abut against a first recess at the lampshade end for precise positioning, and with a first notch on the first end cap, the light emitted by the LED beads near the lamp panel end can effectively pass through the first notch and be fully transmitted directly from the lampshade end, thus completely eliminating the inherent dark area at the end of a single linear light. Furthermore, in lighting scenarios where multiple lights are spliced ​​together end to end, it avoids the formation of dark bands or spots that affect continuity, greatly ensuring the overall lighting quality and visual aesthetics. In addition, by filling the lamp body with a potting compound layer that forms a seamless seal for the lamp panel, it possesses reliable waterproof and insulating properties.

Detailed Implementation

[0031] This utility model provides a dark-area-free LED linear light. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0032] In the description of this utility model, it should be understood that the terms "upper," "lower," "left," and "right," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, 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 a specific orientational structure and operation. Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0033] Please see Figures 1 to 9 As shown, this utility model provides a dark-area-free LED linear light, including: a lamp body 1, a lamp board 2, a lamp shade 3, a first end cap 4, and a second end cap 5; the lamp board 2 is disposed inside the lamp body 1, and LED beads 21 are arranged at intervals along its length on the lamp board 2; the lamp shade 3 is disposed inside the lamp body 1 and is located on the light-emitting side of the lamp board 2, the end of the lamp shade 3 extends to the end of the lamp body 1, and the end of the lamp shade 3 is provided with a first recess 31; two first end caps 4 are respectively disposed at both ends of the lamp body 1, and the side of the first end cap 4 facing the lamp shade 3 is provided with a first notch 41, and on the vertical projection plane, the bottom of the first notch 41 is lower than the bottom of the lamp shade 3; the second end cap 5 is correspondingly installed on the first end cap 4, and the second end cap 5 abuts against the first recess 31.

[0034] In the above description, the end of the lampshade 3 extends to the end of the lamp body 1, while the second end cap 5 abuts against the first recess 31 at the end of the lampshade 3, effectively limiting the horizontal position of the lampshade 3 and preventing it from detaching from the lamp body 1. Figure 5 , 6 As shown, when the LED linear light is working, the light emitted by the LED beads 21 located at the end of the light panel 2 passes through the first notch 41 and is directly emitted from the end area of ​​the lampshade 3, achieving the effect of no dark area at the end of the LED linear light, which significantly improves the lighting effect.

[0035] Preferably, the first end cap 4 is made of transparent or semi-transparent plastic material, which allows some of the light shining on the first end cap 4 to pass through and be transmitted to the end area of ​​the lampshade 3 to emit light, further enhancing the brightness and uniformity of the end light and optimizing the effect of no dark areas.

[0036] In a preferred embodiment, see [reference] Figure 1 , 7The first end cover 4 has two fins 42 on its side wall near the lamp plate 2. The fins 42 are connected to the two side walls of the lamp body 1 by the first screw 43. Through the above connection structure, the overall width of the lamp body 1 is effectively reduced, which is suitable for processing into an extremely narrow line lamp. The first end cover 4 has a support block 44 on the side away from the first notch 41. The support block 44 abuts against the bottom of the lamp body 1, which improves the stability of the first end cover 4 installation and effectively avoids the first end cover 4 from rotating around the axis of the first screw 43 when fixing the position of the first end cover 4 or when installing the second end cover 5 to the first end cover 4.

[0037] In a preferred embodiment, see [reference] Figure 1 , 3 The shape of the first end cap 4 is adapted to the shape of the inner wall of the lamp body 1. Specifically, the lamp body 1 is provided with a first mounting groove 12 and a second mounting groove 13. The lampshade 3 has a T-shaped cross-section. The upper part of the lampshade 3 is installed in the first mounting groove 12, and the first recess 31 is located in the lower part of the lampshade 3. The lamp plate 2 is installed in the second mounting groove 13. By adapting the shape of the first end cap 4 to the inner wall of the lamp body 1, the first end cap 4 can be hidden inside the lamp body 1. At the same time, combined with the fact that the first end cap 4 is made of a deformable plastic material, it can be squeezed into the lamp body 1 and the second mounting groove 13 to improve the sealing performance between the first end cap 4 and the end of the lamp body 1.

[0038] In a preferred embodiment, see [reference] Figure 1 The first end cap 4 has a second recess 45, and the second end cap 5 is installed on the first end cap 4. Specifically, the second end cap 5 is fixed on the second recess 45 of the first end cap 4 by a second screw 52.

[0039] When splicing two LED linear lights end to end, in order to ensure that the ends of the lampshades 3 of the two LED linear lights can fit tightly together, the outer surface of the first end cover 4 is flush with the end face of the lamp body 1, or slightly recessed inward. Similarly, the outer surface of the second end cover 5 is also flush with the outer surface of the first end cover 4, or slightly recessed inward. This effectively avoids interference between the first end covers 4 when splicing two LED linear lights, ensures seamless connection of light at the ends of the lampshades 3, and improves the uniformity and aesthetics of continuous lighting.

[0040] In a preferred embodiment, the distance between the LED bead 21 and the upper surface of the lampshade 3 is 1.2 to 1.4 times the distance between two adjacent LED beads 21. This setting optimizes the light output efficiency of the LED beads 21, ensuring maximum luminous efficacy. Furthermore, the height configuration makes the projection angle and coverage of the light illuminating towards the end of the lamp body 1 more reasonable, increasing the possibility that some light passes through the first notch 41 on the first end cover 4 and is effectively transmitted out from the end area of ​​the lampshade 3. This ensures the brightness and uniformity of the end of a single LED linear light, achieving a true "no dark area at the end" effect. It also indirectly reduces the risk of forming dark bands when multiple LED linear lights are spliced ​​together, ultimately improving the overall luminous efficacy and lighting continuity of the linear light.

[0041] When LED linear lights are used for building exterior decoration, they are susceptible to erosion from rainwater. To ensure that the LED chips 21 can emit light normally and extend their lifespan, please refer to... Figure 1 , 3 4. The lamp body 1 is filled with a potting compound layer 6, which covers the lamp panel 2, forming a reliable waterproof barrier and electrical insulation layer. This effectively isolates moisture intrusion and protects the circuits and components on the lamp panel 2. To further address potential water seepage issues after installation, a first drainage hole 46 is provided on the first end cap 4, and a second drainage hole 51 corresponding to the position of the first drainage hole 46 is provided on the second end cap 5, forming a drainage channel. Small amounts of rainwater or condensate that seep into the lamp body 1 can be smoothly discharged through the first drainage hole 46 and the second drainage hole 51. Since most LED linear lights are arranged vertically, water seeping into the upper LED linear lights can flow along their own drainage holes to the drainage holes of the adjacent lower LED linear lights under the action of gravity, and finally flow to the bottom LED linear lights to be discharged, or directly outward from the gap between the two LED linear lights spliced ​​end to end. This ensures that the water can be continuously and smoothly discharged, completely avoiding water accumulation inside the light body 1, eliminating the risks of water accumulation corroding the circuit, reducing insulation performance, and shortening the life of the light fixture, and greatly improving the protection level and long-term operational reliability of LED linear lights in harsh outdoor environments.

[0042] Further, see Figure 1 , 34. The lamp plate 2 has several second notches 22 on both sides. The second notches 22 are used to allow the potting layer 6 to penetrate into the gap between the lamp plate 2 and the bottom surface of the lamp body 1. The assembly process of the lamp is as follows: First, insert the lamp plate 2 into the second mounting groove 13. At this time, a gap is naturally formed between the bottom of the lamp plate 2 and the inner bottom surface of the lamp body 1. Next, fix the two first end caps 4 to the two ends of the lamp body 1 with the first screws 43. Then, fill the lamp body 1 with potting material. At this time, the potting material not only covers the surface of the lamp plate 2, but also flows smoothly through the multiple second notches 22 on both sides of the lamp plate 2 and fills the gap between the lamp plate 2 and the bottom surface of the lamp body 1 until the liquid level of the potting material covers the upper surface of the lamp plate 2. Finally, it is cured to form a potting layer 6 that completely covers the upper and lower surfaces and edges of the lamp plate 2 without dead corners. Next, align the upper part of the lamp cover 3 with the first mounting groove 12 of the lamp body 1 and insert it into place. Finally, fix the two second end caps 5 to the two first end caps 4 respectively with the second screws 52. At this time, the second end caps 5 abut against the first recesses 31 at both ends of the lamp cover 3 and work together with the first mounting groove 12 to define the final installation position of the lamp cover 3.

[0043] In the above, the potting material can be epoxy resin, PU adhesive, or silicone.

[0044] In a preferred embodiment, see [reference] Figure 8 , 9 The outer side of the first end cap 4 is provided with a horizontally arranged water guide groove 47, which is flush with the end of the lamp body 1. Specifically, the water guide grooves 47 of two adjacent LED strip lights can fit together to form a flow guiding structure. The end of the water guide groove 47 extends to the side wall of the lamp body 1, and the side wall of the lamp body 1 has a third notch 11 corresponding to the position of the water guide groove 47. By setting the water guide groove 47, the drainage channel formed by the first drain hole 46 and the second drain hole 51 is extended to the third notch 11. The water flow discharged from the first drain hole 46 and the second drain hole 51 is directly discharged through the third notch 11 under the guidance of the water guide groove 47, which improves the drainage speed and smoothness of the area between the two lamps connected end to end.

[0045] In summary, this utility model defines the installation position of the lampshade 3 by setting a first notch 41 on the first end cover 4 and mounting the second end cover 5 on the first end cover 4, which abuts against the first recess 31 at the end of the lampshade 3. Combined with the fact that the distance between the LED beads 21 and the upper surface of the lampshade 3 is 1.2 to 1.4 times the distance between two adjacent LED beads 21, some of the light from the LED beads 21 can effectively pass through the first notch 41 and fully shine out from the end of the lampshade 3, completely eliminating the dark area at the end of the LED linear light. Furthermore, when splicing, there are no dark bands or dark spots at the splicing points of the LED linear lights connected end to end, which can ensure lighting quality and aesthetics. The potting of glue inside the lamp body 1 forms a potting layer 6 that covers the lamp plate 2 without dead corners. Together with the drainage channel formed by the end cover drainage hole, the water guide groove 47 and the third notch 11, it realizes the rapid drainage of water inside the lamp, prevents water accumulation, and improves the reliability of the lamp in long-term operation in harsh environments.
