Description

Technical Field

[0001] This utility model relates to the field of LED panel light technology, and more specifically to an anti-glare LED panel light. Background Technology

[0002] LED panel lights are indoor lighting fixtures that use LED beads as the light source. Their lighting principle is to refract and reflect the light emitted by the beads through a special dot design inside the light guide plate, so that the light spreads evenly in the light guide plate and is exported from the front. Then, it is further diffused by the diffuser plate, ultimately forming a uniform planar light emission effect and achieving uniform lighting of the entire panel.

[0003] However, in actual construction, to ensure the lighting intensity of the lamps meets the needs of the actual scene, it is often necessary to increase the power of the LED beads. But when high-power LED beads are used inside panel lights, and the distance between the beads and the light guide plate cannot be flexibly adjusted (for example, the structure of a panel light with a fixed distance between the LED and the light guide plate disclosed in patent CN104421705A), two types of problems easily arise. On the one hand, high-power LED beads have high luminous intensity and stronger light concentration. If the dot design and light transmittance of the light guide plate are not adapted to such strong light... If the light is not properly refracted and diffused by the light guide plate, it will form localized overly bright "spots" on the surface of the light guide plate at the corresponding position of the LED. This will disrupt the uniformity of light emission from the panel light, which can easily cause visual fatigue, especially in scenarios such as offices and classrooms where high light uniformity is required. On the other hand, high-power LEDs generate much more heat than low-power LEDs. If the LED is too close to the light guide plate, the light guide plate will be subjected to continuous high-temperature baking in localized areas, resulting in problems such as deformation, yellowing, and decreased light transmittance. In severe cases, it may even crack, which directly affects the lifespan and lighting effect of the lamp. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an anti-glare LED panel light to solve the problems existing in the background art.

[0005] The utility model provides the following technical solution: an anti-glare LED panel, including a lamp frame, a positioning frame fixedly connected to the bottom of the inner wall of the lamp frame, a fixing post fixedly connected to each of the four corners of the surface of the positioning frame, a light guide plate and a sliding frame slidably connected to the outer surface of the fixing post, a sliding groove matching the fixing post being opened at each of the four corners of the surface of the light guide plate and the sliding frame, an LED lamp panel being fixedly installed on the surface of the sliding frame by screws, a top cover being fixedly installed on the top of the fixing post by screws, a support frame being installed at the center of the upper surface of the sliding frame, a positioning component being installed at the connection between the sliding frame and the support frame, a threaded hole being opened at the center of the top of the support frame, and a bolt being rotatably connected to the center of the top of the top cover by a bearing.

[0006] Furthermore, the positioning component includes a fixing block fixedly connected to the top of the sliding frame, a slot is provided inside the fixing block, a card plate is fixedly connected to the inner wall of the slot, a pin is inserted into the slot, an arc-shaped positioning groove is provided on the top of the pin, the end face of the pin away from the fixing block is fixedly connected to the side of the support frame, and the outer surface of the card plate is engaged with the inside of the arc-shaped positioning groove.

[0007] Furthermore, the outer surface of the bolt is threaded into the inside of the threaded hole, and a wire hole is provided on the top of the top cover.

[0008] Furthermore, the support frame is "n" shaped, and screws are installed at the four corners of the top cover surface, with the outer surface of the screws threaded into the interior of the fixing column.

[0009] Furthermore, the card plate is a stainless steel arc-shaped spring, and the surface of the insertion post away from the support frame is arc-shaped.

[0010] Furthermore, the top of the bolt extends to the upper surface of the top cover, and the sliding frame is longitudinally slidably connected inside the lamp frame.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. This utility model, through the threaded engagement structure of the bolt and support frame, allows for convenient adjustment of the distance between the sliding frame, the LED light board, and the light guide plate. When using high-power LED beads, rotating the bolt clockwise moves the LED light board upward, increasing the distance between it and the light guide plate. This prevents strong light from forming localized "light spots" due to insufficient refraction and diffusion, effectively improving the uniformity of the panel light's illumination and reducing visual fatigue caused by uneven lighting in office, classroom, and other scenarios, thus achieving an anti-glare effect. When replacing with low-power LED beads, the reverse adjustment reduces the distance, ensuring that the light guide plate can efficiently transmit light and guaranteeing stable lighting effects. At the same time, the distance adjustment function also prevents high-power LED beads from baking the light guide plate at close range, reducing the risk of deformation, yellowing, or cracking of the light guide plate and extending the lifespan of the lamp.

[0013] 2. In this utility model, the positioning component, through the plug-in cooperation of the fixing block and the insertion post, and the snap-fit ​​structure of the stainless steel elastic plate and the arc-shaped positioning groove, can provide stable support when the support frame drives the sliding frame to move, preventing the LED light board from shaking and affecting the lighting stability, while ensuring the smoothness of the adjustment process. In addition, the overall structure adopts a screw fixing and sliding connection design, and the top cover, LED light board and other components can be quickly disassembled and assembled with simple tools, which is convenient for later replacement of the light board, maintenance of the light guide plate or adjustment of components, and reduces maintenance costs.

[0020] The present invention will be further described below with reference to specific embodiments. However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0021] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0022] An anti-glare LED panel light includes a light frame 1, a positioning frame 2 fixedly connected to the bottom of the inner wall of the light frame 1, a fixing post 3 fixedly connected to each of the four corners of the surface of the positioning frame 2, a light guide plate 4 and a sliding frame 6 slidably connected to the outer surface of the fixing post 3, and a sliding groove 5 matching the fixing post 3 being opened at each of the four corners of the surface of the light guide plate 4 and the sliding frame 6, an LED light panel 7 fixedly installed on the surface of the sliding frame 6 by screws, a top cover 8 fixedly installed on the top of the fixing post 3 by screws, a support frame 10 installed at the center of the upper surface of the sliding frame 6, a positioning component 9 installed at the connection between the sliding frame 6 and the support frame 10, a threaded hole 12 opened at the center of the top of the support frame 10, and a bolt 11 rotatably connected to the center of the top of the top cover 8 by a bearing.

[0023] In this embodiment, the lamp frame 1 is fixed to four fixed posts 3 by the positioning frame 2, and the light guide plate 4 and the sliding frame 6 slide along the fixed posts 3 by the sliding groove 5 to achieve stable adjustment of their relative positions.

[0024] The LED light board 7 is fixed to the sliding frame 6, and the top cover 8 is connected to the fixing post 3 by screws to form an overall frame. With the cooperation of bolts 11 and threaded holes 12 of the support frame 10, the distance between the LED light board 7 and the light guide plate 4 can be precisely controlled, adapting to different power LED beads and avoiding light spot and high temperature damage problems. The sliding connection design ensures the stability of the adjustment process. The components are positioned by the fixing post 3, resulting in small assembly errors and improving the overall structural reliability.

[0025] Specifically, the positioning component 9 includes a fixing block 91 fixedly connected to the top of the sliding frame 6. The fixing block 91 has a slot 92 inside. A retaining plate 93 is fixedly connected to the inner wall of the slot 92. A plug 94 is inserted into the slot 92. An arc-shaped positioning groove 95 is opened on the top of the plug 94. The end face of the plug 94 away from the fixing block 91 is fixedly connected to the side of the support frame 10. The outer surface of the retaining plate 93 is engaged with the inside of the arc-shaped positioning groove 95.

[0026] In this embodiment, the insertion and engagement of the fixing block 91 and the insertion post 94 provide lateral positioning for the support frame 10 and prevent it from shifting to the left or right.

[0027] The stainless steel elastic plate 93 is inserted into the arc-shaped positioning groove 95 of the insertion post 94 to form an elastic locking structure. It provides damping support when the sliding frame 6 moves up and down, preventing the LED light panel 7 from shaking due to vibration and ensuring lighting stability.

[0028] The curved positioning groove 95 makes contact with the curved surface of the card plate 93, which makes the insertion and removal of the insertion post 94 smooth, facilitates disassembly and maintenance, and ensures connection strength.

[0029] Specifically, the outer surface of the bolt 11 is threaded into the inside of the threaded hole 12, and the top of the top cover 8 has a wire hole.

[0030] In this embodiment, the bolt 11 is rotatably connected to the top cover 8 through the bearing, and its outer surface engages with the threaded hole 12 of the support frame 10. Rotating the bolt 11 can drive the sliding frame 6 to rise and fall along the fixed column 3, realizing stepless adjustment of the spacing, which is convenient to operate and highly accurate.

[0031] The wiring holes on the top cover 8 facilitate the cable lead-out and electrical connection of the LED light board 7, avoiding messy wiring and protecting the cable from crushing damage.

[0032] Specifically, the support frame 10 is "n" shaped, and screws are installed at the four corners of the surface of the top cover 8. The outer surface of the screws is threaded and connected to the inside of the fixing column 3.

[0033] In this embodiment, the support frame 10 adopts an "n" shaped design, which reduces the overall weight and provides stable longitudinal support, ensuring that the driving force of the bolt 11 is evenly transmitted to the sliding frame 6.

[0034] The top cover 8 is fixed to the fixing post 3 by four corner screws, which is a firm connection and easy to disassemble and assemble. The screw connection method reduces the requirements for machining accuracy and facilitates mass production.

[0035] Specifically, the card plate 93 is a stainless steel arc-shaped spring, and the surface of the insertion post 94 away from the support frame 10 is arc-shaped.

[0036] In this implementation scheme, the stainless steel elastic plate 93 has good corrosion resistance and elastic recovery ability, and is not prone to failure after long-term use, thus ensuring the durability of the positioning component 9.

[0037] The arc-shaped end face of the insertion post 94 reduces the frictional resistance between the insertion post and the inner wall of the slot 92 during insertion and removal, making the installation and removal of the support frame 10 easier and avoiding damage to components caused by hard collisions.

[0038] Specifically, the top of bolt 11 extends to the upper surface of top cover 8, and sliding frame 6 is longitudinally slidably connected inside lamp frame 1.

[0039] In this embodiment, the top of bolt 11 extends above the top cover 8, making it easy for users to operate directly by hand or with tools. The spacing can be adjusted without disassembling other parts, thus improving ease of use.

[0040] The sliding frame 6 slides longitudinally along the inner wall of the lamp frame 1. The inner wall of the lamp frame 1 acts as a guide, further limiting the offset of the sliding frame 6, ensuring that the LED light board 7 and the light guide plate 4 always remain parallel, and ensuring the uniformity of light.

[0041] The working principle and usage process of this utility model are as follows: When replacing the high-power LED light board 7, remove the screws at the four corners of the top of the top cover 8 with a screwdriver, and then remove the top cover 8. After removing the top cover 8, use the bolt 11 to pull the support frame 10, sliding frame 6, and LED light board 7 out of the light frame 1 as a whole. Then, turn the bolt 11 counterclockwise to disengage it from the threaded hole 12. At this time, the top cover 8 is separated from the sliding frame 6. Then, slide the support frame 10 laterally away from the positioning component 9. At this time, the support frame 10 pulls the insert 94 out of the slot 92, allowing the support frame 10 to detach from the surface of the sliding frame 6. Then, use a screwdriver to remove the screws connecting the LED light board 7 and the sliding frame 6, and then remove and replace the LED light board 7. Finally, reassemble the LED light board 7 with the sliding frame 6. The components are fixed together, and then the sliding frame 6 is placed inside the lamp frame 1, with the sliding groove 5 on the sliding frame 6 passing through the fixing post 3. Then, the top cover 8 is placed on the top of the lamp frame 1, and the top cover 8 is fixed to the top of the fixing post 3 with screws. Then, by rotating the bolt 11 clockwise and engaging it with the threaded hole 12, when replacing the high-power light source LED lamp board 7, rotating the bolt 11 clockwise will cause the sliding frame 6 and LED lamp board 7 to slide upward through the support frame 10, increasing the distance between the light source and the light guide plate 4, effectively avoiding the dizzying effect caused by the concentrated light source. Conversely, when replacing the low-power light source LED lamp board 7, rotating the bolt 11 clockwise will cause the sliding frame 6 and LED lamp board 7 to slide upward through the support frame 10, decreasing the distance between the light source and the light guide plate 4, ensuring that the light guide plate 4 can evenly conduct the light source.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
