Description

Technical Field

[0001] This utility model relates to the field of LED display auxiliary equipment technology, and more specifically, to an auxiliary lighting mechanism for LED displays. Background Technology

[0002] In today's society, LED displays are widely used in advertising, information display, stage performances, and many other fields. However, in actual use, ambient lighting conditions are often complex and diverse, and relying solely on the light emitted by the LED display itself is insufficient to meet the clear display requirements in various scenarios.

[0003] In dimly lit indoor environments, while LED displays can emit light normally, the details of the displayed content may not be clear enough, making it difficult for viewers to accurately obtain information. In direct outdoor sunlight, the display surface is prone to glare, severely affecting visibility and making the displayed content blurry. To solve these problems, auxiliary lighting is often needed to improve the display effect of LED displays.

[0004] Existing auxiliary lighting equipment for LED displays has several shortcomings. Some devices use simple, fixed installation methods with fixed lighting angles, making it impossible to adjust them according to the actual environment and display needs. This results in auxiliary lighting failing to accurately illuminate the areas of the display screen that need to be highlighted in different scenarios, thus failing to fully realize its purpose.

[0005] Some adjustable auxiliary lighting devices have complex adjustment mechanisms that are inconvenient to operate. Users often need to spend a lot of time and effort to adjust the lighting angle, and may even need to use professional tools, which undoubtedly increases the cost and difficulty of use. Moreover, these complex adjustment mechanisms are prone to loosening due to wear and tear during long-term use, leading to unstable lighting angles.

[0006] Furthermore, the existing connection methods between auxiliary lighting equipment and LED displays are not reasonable enough. Some connection methods are too simple, making the auxiliary lighting equipment prone to detachment or displacement due to vibration or external impact during use, affecting the lighting effect. While some connection methods are more secure, they may damage the LED display during installation and disassembly, affecting the display's lifespan and appearance.

[0007] Meanwhile, existing auxiliary lighting equipment also has shortcomings in terms of lamp installation and replacement. Some lamps require cumbersome installation processes, involving multiple steps and demanding precise installation locations, which not only increases installation difficulty but also reduces work efficiency. Similarly, when lamps malfunction or need to be replaced with different types, the disassembly and replacement process is equally troublesome, causing considerable inconvenience to users. Utility Model Content

[0008] Based on the above-mentioned technical problems, this utility model proposes an auxiliary lighting mechanism for LED displays.

[0009] An auxiliary lighting mechanism for an LED display screen consists of three main parts: a fixture, an adjuster, and a quick-installation structure.

[0010] The fixture features a unique U-shaped structure design, consisting of a top plate, a front clamping plate, and a rear clamping plate. The front clamping plate is vertically positioned below the front end of the top plate, and the rear clamping plate is vertically positioned below the rear end of the top plate. Together, they form a downward-opening clamping groove for holding the display screen frame. This design allows the fixture to be firmly clamped onto the LED display screen frame, providing a stable support base for the entire auxiliary lighting mechanism and ensuring that it will not easily shift or fall off during use.

[0011] The adjuster, a key component for flexible adjustment of the lighting angle, includes a hinge base, a tilt arm, and a mounting base. The hinge base is securely fixed to the upper surface of the top plate, providing a rotatable connection point for the tilt arm. This allows the tilt arm to adjust its tilt angle around the hinge base as an axis. The rear end of the tilt arm is rotatably connected to the hinge base. This connection method gives the tilt arm the ability to rotate flexibly in the vertical plane. Users can adjust the tilt angle according to actual needs to change the illumination direction of the auxiliary lighting. The mounting base is also designed as a U-shaped structure, consisting of a top plate, a front locking plate, and a rear locking plate, forming a downward-opening U-shaped slot. The lower part of the rear locking plate is hinged to the front end of the tilt arm, allowing the mounting base to rotate around the front end of the tilt arm. This further enriches the angle adjustment dimensions of the auxiliary lighting. Through the coordinated rotation of the tilt arm and the mounting base, users can precisely adjust the illumination angle of the auxiliary lighting according to different ambient light conditions and display needs, thereby achieving the best auxiliary lighting effect.

[0012] The quick-installation structure includes a snap-fit ​​structure inside the U-shaped slot and a matching snap-fit ​​structure on the auxiliary lighting fixture housing. The auxiliary lighting fixture can be easily inserted or removed along the direction of the U-shaped slot through the sliding cooperation of the snap-fit ​​structure and the matching snap-fit ​​structure, achieving quick installation and removal from the mounting base. This design greatly simplifies the installation and replacement process of the auxiliary lighting fixture, improves work efficiency, and also allows users to easily replace different types or wattages of auxiliary lighting fixtures according to actual needs.

[0013] As a further optimization: a first locking screw is provided on the rear clamping plate. The first locking screw is threaded into and passes through the rear clamping plate. At the same time, a groove is provided on the inner side of the rear clamping plate, and a pressure plate is movably installed in the groove. The pressure plate is rotatably connected to the front end of the first locking screw. When the user rotates the first locking screw, the rotation of the screw will drive the pressure plate to move along the groove, thereby realizing the clamping or loosening operation of the display screen frame. This design not only enhances the firmness of the connection between the fixture and the display screen frame, but also, through the action of the pressure plate, enables the clamping force to be more evenly distributed on the display screen frame, avoiding damage to the display screen due to excessive local pressure.

[0014] As a further optimization, damping adjustment mechanisms are provided at the hinges of the pitch arm and the hinge base, as well as at the hinges of the pitch arm and the mounting base. These mechanisms change the friction at the hinges by tightening or loosening the damping adjustment bolts. When it is necessary to fix the adjustment angle of the pitch arm or the mounting base, the user can tighten the damping adjustment bolts to increase the friction at the hinges, thereby keeping the pitch arm or the mounting base at the set angle position. Conversely, when it is necessary to adjust the angle, the user can loosen the damping adjustment bolts to reduce the friction, allowing for flexible angle adjustment. This design enables the user to precisely control the angle of the auxiliary lighting according to actual needs, and ensures the stability of the angle after adjustment, avoiding angle changes caused by external vibrations or other factors.

[0015] As a further optimization, a second locking screw is provided on the second rear clamping plate. The second locking screw is threaded into and passes through the second rear clamping plate. When the second locking screw is tightened, its front end will tightly abut against the housing of the auxiliary lighting lamp, thereby limiting the displacement of the lamp. This design further enhances the stability of the auxiliary lighting lamp in the mounting bracket, ensuring that the auxiliary lighting lamp will not shake due to vibration or other external forces during use, thus guaranteeing the stability of the auxiliary lighting effect.

[0016] As a further optimization: the snap-fit ​​structure is designed as a slot or continuous ridge extending longitudinally along the inner side of the U-shaped slot, and the corresponding snap-fit ​​structure is a ridge or slot on the auxiliary lighting housing that matches the slot or ridge. The two are snapped together by longitudinal sliding. This simple and effective snap-fit ​​method not only ensures the firmness of the connection between the auxiliary lighting and the mounting base, but also makes the installation and disassembly process smoother and more convenient.

[0017] As a further optimization: the depth of the U-shaped slot of the mounting base is greater than the height of the auxiliary lighting lamp, and the inner spacing between the second front plate and the second rear plate is a clearance fit with the width of the auxiliary lighting lamp. This design can form a circumferential limit on the auxiliary lighting lamp, ensuring that the position of the auxiliary lighting lamp in the mounting base is accurate and stable, and further improving the reliability and stability of the entire auxiliary lighting mechanism.

[0018] Beneficial effects:

[0019] 1. Flexible angle adjustment: Through the double hinge design of the pitch arm, hinge base, and mounting base in the adjuster, as well as the cooperation of the damping adjustment mechanism, users can accurately and flexibly adjust the illumination angle of the auxiliary lighting according to different ambient light and display needs, thereby effectively improving the display effect of the LED display in various scenarios and meeting diverse visual needs.

[0020] 2. Easy installation and disassembly: The quick installation structure adopts a sliding fit of slots and convex ribs, which realizes the quick installation and disassembly of the auxiliary lighting lamp and the mounting base. The operation is simple and convenient, which greatly improves work efficiency. At the same time, the fixture, through the design of the first locking screw and pressure plate, ensures a firm connection with the display screen frame, while also facilitating the installation and disassembly of the entire auxiliary lighting mechanism without damaging the display screen.

[0021] 3. Stable and reliable connection: The U-shaped clamping structure of the fixture, the clamping design of the first locking screw and the pressure plate, and the limiting of the auxiliary lighting lamp by the second locking screw on the mounting base together ensure the stability of the entire auxiliary lighting mechanism during use, preventing the auxiliary lighting equipment from shifting or falling off due to vibration, collision and other factors, and ensuring the reliability of the auxiliary lighting effect.

[0022] 4. High versatility: The U-shaped slot depth and width design of the mounting base, as well as the versatility of the snap-fit ​​and snap-fit ​​structures, enable this auxiliary lighting mechanism to be compatible with a variety of auxiliary lighting lamps of different sizes and specifications, improving the versatility and applicability of the equipment and reducing the cost for users to replace the entire auxiliary lighting mechanism when changing lamps.

[0027] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] like Figures 1-4 The auxiliary lighting mechanism for an LED display screen shown consists of three main parts: a fixture, an adjuster, and a quick-installation structure.

[0029] Install the fastener: Align the downward-opening clamping groove 107 of the fastener with the display screen frame 500, so that the top plate 101 is above the display screen, the front clamping plate 102 is on the front side of the display screen, and the rear clamping plate 103 is on the rear side of the display screen. Gently put the fastener onto the display screen frame 500, and then rotate the first locking screw 104 to move the pressure plate 106, which is rotatably connected to it, along the groove 105 toward the display screen frame 500, gradually clamping the display screen frame 500. During the clamping process, carefully observe the contact between the pressure plate 106 and the display screen frame 500 to ensure that the clamping force is evenly distributed and to avoid damage to the display screen frame 500. When the pressure plate 106 is tightly attached to the display screen frame 500 and the fastener no longer wobbles, the fastener installation is complete.

[0030] In addition, a rubber buffer layer can be provided on the inside of the retainer and the pressure plate 106.

[0031] Install the regulator and auxiliary lighting 300: The hinge seat 201 is fixed to the upper surface of the top plate 101. The rear end of the pitch arm 202 is rotatably connected to the hinge seat 201. The damping is adjusted by the damping adjustment mechanism 205 so that the pitch arm 202 can rotate flexibly and remain stable after the angle is adjusted. Similarly, the lower part of the rear clamping plate 2033 of the mounting base 203 is hinged to the front end of the pitch arm 202, and the damping is adjusted by the damping adjustment mechanism 205, depending on the type of auxiliary lighting 300 and the actual usage requirements. In this type of structure, friction plates and damping adjustment bolts are conventionally set as the damping adjustment mechanism 205.

[0032] Choose a suitable installation direction, align the locking structure 301 on the housing of the auxiliary lighting lamp 300 with the locking structure 204 inside the U-shaped slot 208 of the mounting base 203, and insert the auxiliary lighting lamp 300 into the U-shaped slot 208 along the slot direction until the locking structure 301 and the locking structure 204 are fully engaged. Then, rotate the second locking screw 207 so that its front end tightly abuts against the housing of the auxiliary lighting lamp 300 to further fix the position of the auxiliary lighting lamp 300.

[0033] The snap-fit ​​structure 204 is designed as a slot or continuous protrusion extending longitudinally along the inner side of the U-shaped slot 208. The corresponding snap-fit ​​structure 301 is a protrusion or slot on the housing of the auxiliary lighting lamp 300 that matches the slot or protrusion. The two are snapped together by longitudinal sliding. This simple and effective snap-fit ​​method not only ensures the firmness of the connection between the auxiliary lighting lamp 300 and the mounting base 203, but also makes the installation and disassembly process smoother and more convenient.

[0034] To ensure the stability of the auxiliary lighting lamp 300 at the U-shaped slot 208, a snap-fit ​​structure 204 can be provided on the top plate 2031, the front snap-fit ​​plate 2032, and the rear snap-fit ​​plate 2033, and the snap-fit ​​mechanisms on the front snap-fit ​​plate 2032 and the rear snap-fit ​​plate 2033 are symmetrically arranged.

[0035] Angle Adjustment: Adjust the illumination angle of the auxiliary lighting 300 according to the actual ambient light and display requirements. If the tilt angle needs to be adjusted, first loosen the damping adjustment bolt at the hinge of the tilt arm 202 and the hinge seat 201, then manually rotate the tilt arm 202 to the required angle, and then tighten the damping adjustment bolt to fix the angle. If the horizontal angle of the auxiliary lighting 300 needs to be further adjusted, loosen the damping adjustment bolt at the hinge of the tilt arm 202 and the mounting seat 203, rotate the mounting seat 203 to the appropriate angle, and then tighten the bolt. During the adjustment process, the display effect of the screen can be observed in real time until the best auxiliary lighting effect is achieved.

[0036] Disassembly and Maintenance: When it is necessary to disassemble the auxiliary lighting mechanism, first rotate the second locking screw 207 to separate its front end from the housing of the auxiliary lighting lamp 300. Then, pull out the auxiliary lighting lamp 300 along the direction of the U-shaped slot 208 to complete the disassembly of the auxiliary lighting lamp 300. If it is necessary to disassemble the entire auxiliary lighting mechanism, first rotate the first locking screw 104 to separate the pressure plate 106 from the display screen frame 500. Then, remove the retainer from the display screen frame 500. During maintenance, if the damping adjustment mechanism 205, locking screw, or other components are found to be loose or worn, they should be tightened or replaced in time to ensure the normal use of the auxiliary lighting mechanism.

[0037] Through the above specific embodiments, the auxiliary lighting mechanism for LED displays of the present invention can provide flexible and reliable auxiliary lighting for LED displays in a high-efficiency and stable manner, significantly improving the display effect of LED displays in different environments.

[0038] 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.
