Description

Technical Field

[0001] This application belongs to the field of LED in-ground light technology, specifically an anti-glare and anti-slip LED in-ground light. Background Technology

[0002] LED in-ground lights are lighting fixtures that are buried underground. They typically use LEDs as the light source and are characterized by energy saving, long lifespan, and soft light. The housing is mostly made of metal or high-strength engineering plastic, which has good waterproof and dustproof performance. They can be used for ground decorative lighting or functional lighting in parks, squares, scenic spots and other places. By pre-burying them in the ground, the light shines out from below the ground, creating a unique light and shadow effect, while not affecting the normal use of the ground and the overall landscape layout.

[0003] For example, the announcement number is for an anti-glare and anti-slip LED in-ground light, which relates to the field of lighting. This anti-glare and anti-slip LED in-ground light includes an in-ground light cover and a light post. The top outer surface of the in-ground light cover is integrally formed with an anti-slip ring. A transparent acrylic plate is fixedly installed on the top of the in-ground light cover. A reflective sleeve is fixedly installed on the inner side wall of the in-ground light cover. LED beads are fixedly installed on the outer surface of the light post. This anti-glare and anti-slip LED in-ground light enhances the internal lumen of the entire in-ground light cover by illuminating the outer surface of the reflective sleeve. Furthermore, the dragon scale anti-slip texture causes the light to be refracted more times when it is reflected upwards, thereby weakening the direct light effect and achieving the anti-glare effect.

[0004] However, in actual use, it was found that the device has multiple lamp posts installed vertically in a circular array inside the reflective sleeve. This makes it cumbersome to remove the sleeve and surrounding parts when maintaining or replacing the lamp posts, increasing the difficulty of later maintenance. At the same time, the light emitted by the LED lamp beads only relies on the reflection of the reflective sleeve. Combined with the refraction of the anti-slip texture, the reflection path is single, which can easily lead to uneven ground lighting with localized areas that are too bright or too dark, affecting the overall visual effect. Therefore, an anti-glare and anti-slip LED in-ground light is provided. Utility Model Content

[0005] The purpose of this application is to provide an anti-glare and anti-slip LED in-ground light in order to solve the problems mentioned above.

[0006] The technical solution adopted in this application is as follows: An anti-glare and anti-slip LED in-ground light includes an in-ground light housing, a sealing protrusion fixedly installed on the top surface of the in-ground light housing, an installation housing provided inside the in-ground light housing, a plurality of inclined protrusions fixedly installed on the side of the installation housing, and LED beads movably passing through the top surface of the plurality of inclined protrusions, an acrylic transparent plate provided on the top surface of the sealing protrusion, an inclined groove opened on the bottom surface of the acrylic transparent plate, one end of the LED bead located inside the inclined groove, and a plurality of triangular protrusions fixedly installed on the inner sidewall of the inclined groove.

[0007] In a preferred embodiment, the top surface of the acrylic transparent plate is provided with a circular fixing cover, the top surface of the circular fixing cover is provided with multiple through holes, and each of the multiple through holes is provided with an internal hexagon bolt. The top surface of the inground lamp housing is provided with a threaded hole corresponding to the internal hexagon bolt, and the bottom end of the internal hexagon bolt is threaded into the inside of the threaded hole.

[0008] In a preferred embodiment, the top surface of the sealing protrusion has an annular groove, and a sealing gasket is disposed inside the annular groove.

[0009] In a preferred embodiment, the top surface of the acrylic transparent plate is provided with multiple anti-slip grooves, and the top surface of the circular fixing cover is fixedly installed with an anti-slip rubber pad.

[0010] In a preferred embodiment, a cable connector is fixedly installed on the bottom side of the inground lamp housing.

[0011] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0012] 1. In this application, due to the adoption of the above-mentioned scheme, after the LED lamp bead is powered on and emits light, the light is first refracted at the light-transmitting material interface of the inclined convex plate. Since the refractive index of the convex plate material is greater than that of air, the light will be deflected in the direction of the normal, causing the originally vertically upward light to propagate obliquely. When the light enters the inclined groove, part of the light directly illuminates the triangular protrusion, while the other part is reflected on the side wall of the groove. The light can undergo multiple reflections in the groove before being emitted. Each reflection further disperses the light energy. When the light illuminates the surface of the protrusion, diffuse reflection occurs, and the light is reflected in multiple directions. Thus, through the refraction of the inclined convex plate, the reflection of the inclined groove, and the diffuse reflection of the triangular protrusion, the direction of light propagation is changed multiple times and evenly dispersed, effectively reducing the light intensity per unit area and achieving the anti-glare effect. This device can effectively solve the problem of inconvenient maintenance of in-ground lights, improve the uneven light distribution, and achieve anti-glare and anti-slip functions.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the embodiments of this application. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] refer to Figure 1 , Figure 6 As shown, an anti-glare and anti-slip LED in-ground light includes an in-ground light housing 1. A cable connector 16 is fixedly installed on the side of the in-ground light housing 1 near the bottom end. A sealing protrusion 2 is fixedly installed on the top surface of the in-ground light housing 1. An annular groove 12 is formed on the top surface of the sealing protrusion 2. A sealing gasket 13 is provided inside the annular groove 12. The cable connector 16 facilitates the connection between the in-ground light and external circuits, ensuring stable power transmission. The sealing protrusion 2, together with the annular groove 12 and the sealing gasket 13, forms a multi-seal structure, which can effectively prevent rainwater, dust and other external debris from entering the interior of the in-ground light, improve the waterproof and dustproof performance of the light fixture, and extend its service life.

[0022] The in-ground light housing 1 has an internal mounting housing 3. Multiple inclined protrusions 4 are fixedly mounted on the sides of the mounting housing 3, and LED beads 5 are movably inserted through the top surface of each of the inclined protrusions 4. An acrylic transparent plate 6 is mounted on the top surface of the sealing protrusion 2, and an inclined groove 7 is formed on the bottom surface of the acrylic transparent plate 6. One end of the LED bead 5 is located inside the inclined groove 7, and multiple triangular protrusions 8 are fixedly mounted on the inner wall of the inclined groove 7. Through the arrangement of the inclined protrusions 4 and the inclined groove 7, the light emitted by the LED beads 5 undergoes multiple refractions and reflections during propagation, effectively dispersing the light and preventing direct light from shining into the eyes, thus achieving anti-glare function. Simultaneously, the multiple triangular protrusions 8 further alter the light propagation path, making the light distribution more uniform and improving the ground lighting effect. Furthermore, a circuit board is installed inside the mounting housing 3, and the LED beads 5 are connected to the circuit board, facilitating power transmission and control. The LED beads 5 are movably inserted through the inclined protrusions 4, making them easy to disassemble and replace, reducing the difficulty of later maintenance. Compared to traditional structures, it eliminates the need to remove a large number of surrounding components, making operation more convenient.

[0023] refer to Figure 1 , Figure 6 As shown, a circular fixing cover 9 is provided on the top surface of the acrylic transparent panel 6. Multiple anti-slip grooves 14 are provided on the top surface of the acrylic transparent panel 6, and an anti-slip rubber pad 15 is fixedly installed on the top surface of the circular fixing cover 9. Through the double anti-slip design of the anti-slip grooves 14 and the anti-slip rubber pad 15, the friction of the top surface of the inground light can be increased, effectively preventing pedestrians or vehicles from slipping when passing by, ensuring safety. At the same time, the circular fixing cover 9 can protect the acrylic transparent panel 6, reduce the direct impact of external forces on it, and extend the service life of the acrylic transparent panel 6.

[0024] refer to Figure 1 , Figure 6 As shown, the top surface of the circular fixing cover 9 has multiple through holes 10, and each of the multiple through holes 10 is provided with an internal hexagon bolt 11. The top surface of the inground lamp housing 1 has a threaded hole corresponding to the internal hexagon bolt 11, and the bottom end of the internal hexagon bolt 11 is threaded into the inside of the threaded hole. By using the internal hexagon bolt 11 to engage with the threaded hole on the top surface of the inground lamp housing 1 through the through hole 10, the circular fixing cover 9 can be firmly fixed to the inground lamp housing 1. The installation and disassembly process is simple and quick, and it is convenient to inspect and maintain the internal acrylic transparent plate 6, LED lamp beads 5 and other components.

[0025] The implementation principle of this application's anti-glare and anti-slip LED in-ground light embodiment is as follows: During use, an external power supply is connected via cable connector 16, and the LED bead 5 is powered on and emits light. When the LED bead 5 is powered on and emits light, the light is first refracted at the light-transmitting material interface of the inclined convex plate 4. Because the refractive index of the convex plate material is greater than that of air, the light is deflected towards the normal direction, causing the originally vertically upward light to propagate obliquely. When the light enters the inclined groove 7, part of the light directly illuminates the triangular protrusion 8, while the other part is reflected on the side wall of the groove. This allows the light to undergo 2-3 reflections within the groove before exiting. Each reflection further disperses the light energy. The triangular protrusion 8 adopts an isosceles right-angled triangular cross-section design, and its surface is treated with a frosted finish to form a micro-roughness. When light illuminates the surface of the protrusion, diffuse reflection occurs. As light is reflected in multiple directions, the direction of light propagation is changed and evenly dispersed multiple times through refraction by the inclined convex plate 4, reflection by the inclined groove 7, and diffuse reflection by the triangular protrusion 8, effectively reducing the light intensity per unit area and achieving an anti-glare effect. The device uses an acrylic transparent plate 6 to allow light to pass through and protect the internal structure. The anti-slip groove 14 on the plate and the anti-slip rubber pad 15 on the top surface of the circular fixing cover 9 work together to prevent the surface from slipping. The circular fixing cover 9 is fixed to the in-ground lamp housing 1 by hexagonal bolts 11 to ensure the stability of the overall structure. The sealing structure composed of the sealing protrusion 2, the annular groove 12, and the sealing gasket 13 ensures that the interior of the in-ground lamp is not affected by the external environment. In this way, the problem of inconvenient maintenance of existing in-ground lamps is solved, and the uneven light distribution is improved, achieving efficient anti-glare and anti-slip functions.
