Description

Technical Field

[0001] This utility model relates to the field of lighting fixtures, and more specifically, to an LED street light. Background Technology

[0002] A typical LED street light consists of a housing, an LED light source module, a driver, and a light-transmitting cover. The housing usually has an open structure on one side, which is covered by the light-transmitting cover to seal the housing. The LED light source module is installed inside the housing and can illuminate outwards through the light-transmitting cover.

[0003] Sealing between the light-transmitting cover and the housing is relatively simple. A ring-shaped sealing ring is typically embedded at the opening, creating a single-layer seal that provides some waterproofing. However, this seal is less effective in outdoor or harsh environments. Furthermore, current methods typically use screws to connect and fix the light-transmitting cover to the housing. These screws penetrate the cover, creating through-holes. While a sealant can be used between these holes and the screws, this creates a weak point in the seal and poses a potential safety hazard. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide an LED street light that improves the long-term waterproof and sealing reliability in outdoor and harsh environments.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: an LED street light includes a housing, a light-transmitting cover, a sealing ring, a reflector, and an LED bead board. One side of the housing is integrally connected to a base plate, while the other side is open and covered by the light-transmitting cover. The base plate is integrally formed with a raised ring, which surrounds the inner circumference of the housing and forms an annular groove with the inner circumference of the housing. The sealing ring is nested within the side of the raised ring facing the light-transmitting cover, and the light-transmitting cover and the raised ring are sealed by the sealing ring. The inner circumference of the raised ring, the base plate, and the light-transmitting cover together form an inner cavity for accommodating the LED bead board. A connecting post is fixedly connected within the annular groove, and the light-transmitting cover is fixedly connected to the connecting post by a screw. The light-transmitting cover has a connecting notch for the screw to pass through, and the connecting notch is located on the outer circumference of the sealing ring.

[0006] By adopting the above solution, a convex ring is integrally formed on the bottom plate of the housing and a ring groove is provided, so that the sealing ring is located between the convex ring and the light-transmitting cover to form a reliable seal, which effectively improves the sealing performance between the light-transmitting cover and the housing; the connection notch on the light-transmitting cover is located on the outside of the sealing ring, which further avoids the damage to the seal integrity caused by screw penetration and improves the waterproof rating and environmental adaptability of the LED street light.

[0007] The present invention is further configured such that the outer side of the connecting notch is covered by a fixing plate, and the screw head of the screw abuts against the fixing plate.

[0008] By adopting the above solution, a fixed pressure plate is used to cover the outside of the connection notch, and the screw head of screw one presses against the fixed pressure plate, making the connection between the light-transmitting cover and the connecting column more secure and uniform, effectively dispersing the fastening pressure, and avoiding deformation or cracking of the light-transmitting cover caused by excessive local stress.

[0009] The present invention is further configured such that an inwardly recessed embedding groove is provided on one side edge of the sealing ring, and a portion of the convex ring is embedded in the embedding groove.

[0010] By adopting the above solution, an inwardly recessed embedding groove is set on one side edge of the sealing ring, and the convex ring is embedded therein, forming a tightly interlocking mechanical seal structure. This enhances the fixing stability and sealing reliability of the sealing ring, and effectively prevents it from shifting or loosening during installation or vibration.

[0011] The present invention is further configured such that the LED bead board is fixedly connected to the base plate by screws, and a reflector is installed between the LED bead board and the light-transmitting cover. The reflector has an annular structure with open ends, and the light-emitting part of the LED bead board is located on the inner circumference of the reflector.

[0012] By adopting the above solution, the LED bead board is securely installed on the base plate with screws, and an open-ended annular reflector is set between it and the light-transmitting cover. This ensures that the light-emitting part of the LED bead board is located on the inner circumference of the reflector, which not only achieves reliable fixing of the bead board and avoids displacement or loosening, but also effectively gathers and reflects light through the reflector, thereby improving lighting efficiency and light utilization.

[0013] The present invention is further configured such that one end of the reflector has an abutment part one and the other end has an abutment part two, the abutment part one abuts against the LED lamp bead board, and the abutment part two abuts against the light-transmitting cover.

[0014] By adopting the above solution, by setting abutment part one and abutment part two at both ends of the reflector, one end of which is firmly pressed against the LED lamp bead board and the other end is tightly fitted to the light-transmitting cover, the positioning accuracy and installation stability of the reflector are effectively enhanced, and displacement or loosening during use is avoided. At the same time, the double-end pressing design further optimizes the structural fit between components, improving the reflectivity and light uniformity.

[0015] The present invention is further configured such that a supporting convex ring is integrally formed on the inner circumference of the convex ring; a portion of the sealing ring one extends into the inner circumference of the convex ring and is integrally formed with a flanged portion one; the outer circumference of the abutting portion two of the reflector is integrally formed with a flanged portion two; the supporting convex ring, flanged portion one, and flanged portion two abut against each other and seal.

[0016] By adopting the above solution, the flanged part 1 extending inward from the sealing ring 1 cooperates with the flanged part 2 on the reflector, so that the supporting convex ring, flanged part 1 and flanged part 2 are tightly pressed together, which improves the sealing reliability between the reflector and the housing, effectively prevents water, dust and other pollutants from entering the light source cavity, and enhances the structural stability and vibration resistance of the components.

[0017] The present invention is further configured such that the flange portion one of the sealing ring one is located between the supporting convex ring and the flange portion two.

[0018] By adopting the above solution, a multi-layered, tightly pressed composite sealing structure is formed by placing the flanged portion of sealing ring one between the supporting convex ring and the flanged portion two of the reflector. This enhances the sealing synergy between the components, effectively fills assembly gaps, and eliminates the penetration paths of moisture and dust. Simultaneously, the central placement of flanged portion one helps to evenly distribute the clamping force, improving the reliability and stability of the interface seal.

[0019] The present invention is further configured such that a sealing ring groove is provided at the second abutment part of the reflector, and a sealing ring is embedded in the sealing ring groove, and the sealing ring, the abutment part and the light-transmitting cover press against each other to seal.

[0020] By adopting the above solution, a sealing ring groove is set at the second contact part of the reflector and a second sealing ring is embedded therein, so that the second sealing ring, the contact part, and the light-transmitting cover are tightly pressed together to form a sealing barrier. The multi-stage compression sealing structure not only optimizes the stress distribution, but also provides multiple supports for the light-transmitting cover, ensuring that the luminaire maintains safe and stable optical performance and service life in harsh environments such as outdoor vibration and temperature changes.

[0021] The present invention is further configured such that a first connecting seat is connected to the upper end of the adapter arm, and a second connecting seat is connected to the lower end of the housing. The first connecting seat has an arc-shaped groove along its length. A second screw is provided between the first connecting seat and the second connecting seat. The second screw passes through the arc-shaped groove to fasten the first connecting seat and the second connecting seat.

[0022] By adopting the above solution, and by creating an arc-shaped groove on the connecting seat one at the upper end of the adapter arm, and using screw two to securely connect it to the connecting seat two at the lower end of the housing, flexible adjustment of the LED street light's illumination angle within a continuous range is achieved. The arc-shaped groove design ensures connection strength while making angle adjustment smoother and more stable, improving lighting performance and user experience.

[0023] The present invention is further configured such that the first connecting seat is provided with a limiting protruding tooth, and the second connecting seat is provided with a limiting concave tooth. The limiting concave tooth and the limiting protruding tooth mesh with each other for self-locking and fixing between the first connecting seat and the second connecting seat.

[0024] By adopting the above scheme, and by setting mutually meshing limiting protruding teeth and limiting concave teeth on connecting seat one and connecting seat two respectively, reliable self-locking and fixation after adjustment are achieved. This tooth meshing structure effectively prevents slippage or displacement at the connection point due to vibration or external force, ensuring long-term stability after the irradiation angle is adjusted. At the same time, the self-locking design simplifies the fixing operation, eliminating the need for additional fastening components, which not only improves the installation and adjustment efficiency but also enhances the rigidity and durability of the overall structure.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. By adopting a multi-seal structure at the connection of the light-transmitting cover, the long-term waterproof and sealing reliability in outdoor and harsh environments is significantly improved, effectively eliminating the hidden dangers of single-seal.

[0027] 2. By forming an annular groove between the outer wall of the housing and the convex ring, the connection position of the screw to the light-transmitting cover is located at the annular groove and connected to the outer periphery of the sealing ring. The hole through which the screw passes through the light-transmitting cover is separated from the space for accommodating the LED lamp bead board, so as not to cause water leakage in the space for accommodating the LED lamp bead board.

[0028] 3. By setting a rotatable and adjustable structure between the housing and the adapter arm, the illumination angle of the LED street light can be flexibly adjusted within a continuous range, which facilitates quick dimming during installation and subsequent maintenance. The operation is simple and reliable, effectively improving the applicability and scene adaptability of the lamp. Attached Figure Description

[0037] 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.

[0038] Example 1

[0039] This embodiment discloses an LED street light, referring to... Figures 1-5 As shown, it includes a housing 1, a light-transmitting cover 2, a sealing ring 3, a reflector 4, and an LED light bead board 5.

[0040] One side of the housing 1 is integrally connected to a base plate 101, while the other side of the housing 1 is open. A raised ring 102 is integrally formed on the base plate 101, located inside the housing 1. The raised ring 102 surrounds the inner circumference of the housing 1 and forms an annular groove 103 with the inner circumference of the housing 1. Specifically, the housing 1 is made of aluminum alloy. The outer circumference of the housing 1, the base plate 101, and the raised ring 102 are integrally formed. Furthermore, multiple reinforcing ribs 106 are integrally formed on the surface of the base plate 101, which enhances the overall strength of the housing 1. Additionally, the aluminum alloy shell also serves as a heat dissipation layer for the LED light.

[0041] In addition, in this embodiment, the LED street light also includes a power controller, which is installed on the back of the housing 1 and has an external structure, so as not to occupy the space inside the housing 1 and make the housing 1 thinner. The connection between the power controller and the housing 1 is sealed by a sealing element, which can be specifically set according to the shape of the connection.

[0042] The light-transmitting cover 2 has a plate-like structure with a light-transmitting effect, which is installed on one side of the opening of the housing 1 and can close the opening of the housing 1.

[0043] Sealing ring 3 is installed between the convex ring 102 and the light-transmitting cover 2. The light-transmitting cover 2 and the convex ring 102 are approximately planar in shape. After the light-transmitting cover 2 is installed, a compressive force is formed between the light-transmitting cover 2, sealing ring 3, and convex ring 102, which can maintain the seal of the inner circumferential space of the convex ring 102. Sealing ring 3 can achieve the first seal between the light-transmitting cover 2 and the convex ring 102.

[0044] To improve the installation stability between the sealing ring 3 and the convex ring 102, an inwardly recessed embedding groove 301 is provided on one side edge of the sealing ring 3. Part of the convex ring 102 is embedded in the embedding groove 301 to form a mechanical interlocking sealing structure, thereby improving the sealing reliability.

[0045] The light-transmitting cover 2 and the housing 1 are connected and fixed by a number of screws 701. Specifically, a connecting post 104 is fixedly connected in the annular groove 103. The connecting post 104 is also integrally formed with the housing 1, and holes for connecting screws 701 are pre-machined on the connecting post 104.

[0046] The light-transmitting cover 2 is fixedly connected to the connecting post 104 by screws 701. A connection notch 201 is provided on the light-transmitting cover 2 corresponding to the position where screws 701 pass through. The screw head of screw 701 abuts against the fixing plate 7, ensuring a secure connection while further enhancing waterproof and dustproof capabilities. The fixing plate 7 covers the outside of the connection notch 201. On the one hand, the fixing plate 7 can roughly cover and close the connection notch 201; on the other hand, the fixing plate 7 can increase the contact area between the screw head of screw 701 and the light-transmitting cover 2, thus maintaining a stable and reliable installation.

[0047] Reference Figure 3 , Figure 4 As shown, a sealing ring 3 is used to seal the light-transmitting cover 2 and the convex ring 102. The inner circumference of the convex ring 102, the base plate 101, and the light-transmitting cover 2 together form an inner cavity that can accommodate the LED bead board 5. The LED bead board 5 is fixedly connected to the base plate 101 with screws. The LED bead board 5 can be in a relatively sealed cavity, avoiding the adverse effects of water leakage.

[0048] A reflector 4 is installed between the LED bead board 5 and the light-transmitting cover 2. The reflector 4 has an open-ended ring structure. The light-emitting part of the LED bead board 5 is located on the inner circumference of the reflector 4. The reflector 4 can effectively gather and reflect light, thereby improving light output efficiency and lighting uniformity.

[0049] One end of the reflector 4 has a first abutment portion 401, and the other end has a second abutment portion 402. The first abutment portion 401 abuts against the LED lamp bead board 5 to achieve axial positioning and fixation of the reflector 4. The second abutment portion 402 abuts against the surface of the light-transmitting cover 2 to further enhance structural stability. A positioning structure can be provided between the reflector 4 and the housing 1. Specifically, it can be a structure in which a positioning groove and a positioning block cooperate to position the reflector 4, ensuring that the position of the reflector 4 is in a roughly determined state.

[0050] Reference Figure 5 As shown, the upper end of the adapter arm 6 is connected to a connecting seat 601, and the lower end of the housing 1 is connected to a connecting seat 107. The housing 1 can be installed and supported through the adapter arm 6.

[0051] A rotatable and adjustable structure is also adopted between the adapter arm 6 and the housing 1. The connecting seat 601 has an arc-shaped groove 603 along its length. The connecting seat 601 and the connecting seat 107 are fastened together by a screw 8 passing through the arc-shaped groove 603. The contact points between the connecting seat 601 and the connecting seat 107 are uniformly arc-shaped, and their direction is consistent with the arc-shaped groove 603. During adjustment, the screw 8 can be loosened to adjust the relative position of the connecting seat 601 and the connecting seat 107. After adjustment, the screw 8 can be tightened again to fix the connection.

[0052] Furthermore, a limiting protrusion 602 can be pre-formed on the side of the connecting seat 1 601 facing the connecting seat 2 107, and a limiting concave tooth 108 can be formed at the corresponding position of the connecting seat 2 107. The limiting concave tooth 108 and the limiting protrusion 602 are interlocked. When the screw 2 8 is tightened, the limiting protrusion 602 can be embedded in the limiting concave tooth 108, realizing self-locking and fixing between the connecting seat 1 601 and the connecting seat 2 107. This can effectively prevent the connection from loosening or the angle from shifting, and ensure that the LED street light can maintain a reliable working state in various environments.

[0053] Example 2

[0054] This embodiment discloses an LED street light, which is based on Embodiment 1 and further refers to... Figure 6 , Figure 7 Please provide a detailed explanation.

[0055] A supporting protruding ring 105 is integrally formed on the inner circumference of the protruding ring 102, forming an additional structural support and sealing interface around the inner circumference of the protruding ring 102. A portion of the sealing ring 3 extends into the inner circumference of the protruding ring 102 and is integrally formed with a flange portion 302, which can abut against the surface of the supporting protruding ring 105.

[0056] The outer circumference of the abutment portion 402 of the reflector 4 is integrally formed with a flange portion 403. The flange portion 403 can press against the flange portion 302 of the sealing ring 3.

[0057] During installation, the supporting convex ring 105, the first flange 302, and the second flange 403 press against each other to seal, and the first flange 302 of the sealing ring 3 can be pressed between the supporting convex ring 105 and the second flange 403. Since the material of the first flange 302 is the same as that of the sealing ring 3, it has an elastic sealing effect. The first flange 302 of the sealing ring 3 is located between the supporting convex ring 105 and the second flange 403, forming a sandwich-type sealing structure, which not only optimizes pressure distribution and improves sealing uniformity, but also enhances vibration resistance and deformation resistance.

[0058] The supporting convex ring 105, the first flange 302 and the second flange 403 together form another sealing structure, which improves the sealing reliability between the interfaces and effectively prevents the intrusion of water vapor and dust.

[0059] Since the reflector 4 is typically supported by plastic material and directly presses against the light-transmitting cover 2, it cannot effectively achieve a sealing effect. To further improve the sealing system, a sealing ring groove 404 is provided at the contact portion 402 of the reflector 4, and the sealing ring groove 404 surrounds the reflector 4. Furthermore, a sealing ring 9 is embedded in the sealing ring groove 404. The sealing ring 9 can press against the surface of the light-transmitting cover 2, and the sealing ring 9, the contact portion 402, and the light-transmitting cover 2 press against each other to form a sealing barrier. Moreover, the sealing ring 9 can also provide elastic support for the light-transmitting cover 2, maintaining the installation stability of the light-transmitting cover 2.

[0060] This design significantly improves the long-term sealing performance of the luminaire in harsh environments, ensuring that the internal optical components are not contaminated and guaranteeing the stable luminous efficiency and lifespan of the LED streetlights.

[0061] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
