Abstract
Description
Technical Field
[0001] This utility model relates to a polygonal lamp, belonging to the technical field of lighting fixtures. Background Technology
[0002] With the development of modern architectural design and the improvement of people's aesthetic concepts, lighting equipment not only needs to meet basic functional requirements, but also should possess decorative and artistic qualities. Polygonal luminaires, as a new type of lighting equipment, have received widespread attention and application due to their unique geometric shapes and diverse lighting effects.
[0003] Polygonal lighting fixtures utilize various polygonal geometric shapes, such as quadrilaterals, pentagons, and hexagons. This not only increases the visual diversity of the fixtures but also creates unique lighting effects through different light refraction and reflection effects, as well as the combination of different fixtures, thus enhancing the aesthetics and atmosphere of a space.
[0004] However, this type of polygonal lamp has the following problems:
[0005] 1. In order to cover the LEDs, the frames of common polygonal lamps are usually set to be relatively wide. This makes the non-light-emitting area at the joint of the frames of two polygonal lamps very obvious when they are combined for decoration, resulting in an unsightly overall appearance.
[0006] 2. Most common polygonal light fixtures are for decorative purposes, so the brightness does not need to be too high. However, in order to ensure the uniformity of light emission, most common polygonal lights are arranged along the entire perimeter, which leads to a relatively high overall cost. Utility Model Content
[0007] In order to solve the above-mentioned problems existing in the prior art, this utility model provides a polygonal lamp.
[0008] The technical solution of this utility model is as follows:
[0009] A polygonal lamp includes a polygonal base shell with an open top surface. Inside the base shell, from bottom to top, are a light source plate, reflective paper, a light guide plate, and a diffuser plate. The light source plate has several LED beads. The reflective paper has corresponding clearance openings for each LED bead. The light guide plate has corresponding clearance grooves for each LED bead. Each LED bead passes through a clearance opening and is inserted into a clearance groove. Each clearance groove contains black and white adhesive, with the white side of the adhesive bonded to the sidewall of the groove. The light guide plate has dots; the dots near the LED beads are recessed, and the dots at the edges of the light guide plate are reinforced.
[0010] The light source plate, reflective paper, light guide plate and diffuser plate are all shaped like the bottom shell, and the lamp beads are arranged at each corner of the light source plate.
[0011] The reflective paper has a frosted finish on the side closest to the light guide plate.
[0012] The diffuser plate is arranged to cover the top surface of the bottom shell.
[0013] The light source board has heat dissipation grooves, and the reflective paper and light guide plate are both arranged to cover the heat dissipation grooves.
[0014] The outer wall of the bottom shell is also equipped with a controller, which is electrically connected to each LED.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model, by setting up a structure including a bottom shell, a light source plate, reflective paper, a light guide plate, and a diffuser plate, creates an avoidance groove on the light guide plate and places black and white adhesive in the avoidance groove. By bonding the white side of the black and white adhesive to the side wall of the avoidance groove, the black side of the black and white adhesive can face the LED bead, thus covering the bright spot of the LED bead. This eliminates the need for a wide frame of the bottom shell, allowing the frame to be set very narrow. This greatly reduces the area of the non-light-emitting area at the splicing of the polygonal lamp frame, and compared with the prior art, it has the advantage of improving the overall aesthetics after splicing.
[0017] 2. This utility model achieves this by specifically setting the dots on the light guide plate. Specifically, the dots close to the LED beads on the light guide plate are left unsupported, while the dots at the edges of the light guide plate are reinforced. The unsupported area reduces the direct strong light from the LED beads, and the reinforcement compensates for the missing dots on the light guide plate after the unsupported area is removed. This results in relatively uniform light emission from the light-emitting surface of the light guide plate. Compared with the prior art, it eliminates the need for LEDs to be placed along the entire perimeter, resulting in uniform overall light emission without obvious dark or bright areas. This has the advantages of reduced costs and higher product competitiveness. Attached Figure Description

[0026] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0027] Example: Please refer to Figures 1-6 This embodiment provides a polygonal lamp, including a polygonal base shell 1. The specific structure of the base shell 1 can be determined according to actual conditions. In this embodiment, the base shell 1 has a hexagonal structure. The top surface of the base shell 1 has an open structure. Inside the base shell 1, from bottom to top, a light source plate 2, a reflective paper 3, a light guide plate 4, and a diffuser plate 5 are arranged sequentially. The shapes of the light source plate 2, the reflective paper 3, the light guide plate 4, and the diffuser plate 5 are all the same as the shape of the base shell 1, that is, they are all hexagonal structures. The light source plate 2, the reflective paper 3, and the light guide plate 4 are adapted to the bottom structure of the base shell 1 so that they can be installed inside the base shell 1. The diffuser plate 5 is arranged to cover the top surface of the base shell 1 to provide a sealing effect and prevent light leakage.
[0028] A number of LED beads 6 are provided on the light source board 2. Each of the top corners of the light source board 2 is provided with an LED bead 6. The specific number of LED beads 6 can be determined according to the actual situation. In this embodiment, one LED bead 6 is provided at each top corner of the light source board 2. The reflective paper 3 has clearance openings 7 that correspond one-to-one with the LED beads 6, and the light guide plate 4 has clearance grooves 8 that correspond one-to-one with the LED beads 6. After the reflective paper 3 and the light guide plate 4 are sequentially placed on the light source plate 2, each LED bead 6 is inserted into its corresponding clearance groove 8 after passing through its corresponding clearance opening 7. Each clearance groove 8 is filled with black and white adhesive. The white side of the black and white adhesive in each clearance groove 8 is bonded to the side wall of the clearance groove 8, so that the black side of the black and white adhesive is close to the corresponding LED bead 6. This allows the black and white adhesive to cover the bright spots of the LED bead 6, so that the frame of the bottom shell 1 does not need to be set wider to cover the LED bead 6. The frame of the bottom shell 1 can be set very narrow, which can greatly reduce the area of the non-light-emitting area at the splicing of the polygonal lamp frame and greatly improve the overall aesthetics of the spliced polygonal lamp.
[0029] The light guide plate 4 has dots 9. These dots are designed to evenly distribute the light emitted by the LED beads 6 across the entire surface of the light guide plate 4, ensuring uniform light emission from its emitting surface. The dots 9 near the LED beads 6 on the light guide plate 4 are spaced out, meaning the dots 9 at each corner of the light guide plate 4 are more sparsely distributed. The dots 9 along the upper edges of the light guide plate 4 are reinforced, meaning the dots 9 along all six edges are more densely distributed. The specific density of the dots 9 can be determined based on actual conditions. The spaced-out dot treatment reduces the direct, strong light from the LED beads 6, while the reinforced dot treatment compensates for any missing dots 9 on the light guide plate 4, resulting in relatively uniform light emission from the emitting surface. This eliminates the need for lighting along the entire circumference of the base, reducing costs, and ensures uniform overall light emission from the polygonal luminaire without significant dark or bright areas, thus enhancing product competitiveness.
[0030] In this embodiment, the surface of the reflective paper 3 closest to the light guide plate 4 is frosted. The light guide plate 4 and the reflective paper 3 may adhere to each other due to electrostatic or surface properties of the materials. This adhesion can cause the reflective paper 3 to adhere tightly to the light guide plate 4, making separation difficult. This not only affects the smooth progress of the production process but may also cause wrinkles or damage to the reflective paper 3, thus affecting the lighting effect. By frosting the surface of the reflective paper 3 closest to the light guide plate 4, the accumulation of electrostatic charge and surface adhesion on this side can be reduced, thereby effectively suppressing the adhesion between the reflective paper 3 and the light guide plate 4.
[0031] In this embodiment, a heat dissipation groove 10 is provided on the light source plate 2, and the heat dissipation groove 10 is arranged through the light source plate 2 to perform the required heat dissipation work. The reflective paper 3 and the light guide plate 4 are both arranged to cover the heat dissipation groove 10 to avoid possible light leakage and other phenomena.
[0032] In this embodiment, a controller 11 is also provided on the outer wall of the bottom shell 1, and the controller 11 is electrically connected to each lamp bead 6. The controller 11 is used to control the working state of each lamp bead 6 as required.
[0033] In this embodiment, during assembly, the LED beads 6 are first installed on the light source plate 2, then the light source plate 2 is installed inside the bottom shell 1, and then the reflective paper 3 is placed on the light source plate 2, so that the LED beads 6 pass through the corresponding clearance slots 7, and the frosted surface of the reflective paper 3 is set away from the light source plate 2. After that, the light guide plate 4 is placed on the reflective paper 3, so that the LED beads 6 are inserted into the corresponding clearance slots 8, and then the diffuser plate 5 is placed on the top surface of the bottom shell 1, so that the diffuser plate 5 covers the top surface of the bottom shell 1, and then the diffuser plate 5 is welded together with the bottom shell 1. In this embodiment, when performing lighting work, the operator controls the lamp beads 6 to start working by using the controller 11. The light emitted by the lamp beads 6 can be emitted through the reflective paper 3 and enter the light guide plate 4. The light entering the light guide plate 4 can be evenly distributed in the light guide plate 4 by the action of the dots 9, and finally emitted from the light-emitting surface of the light guide plate 4, that is, the top surface of the light guide plate 4, and then enters the diffuser plate 5. The diffuser plate 5 diffuses the incoming light and emits it outward, thus completing the required lighting work.

Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
