Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of LED lighting, specifically a frameless panel light for label backlighting. Background Technology
[0002] Direct-emitting panel lights are widely used in commercial and residential environments, offering advantages such as uniform illumination and soft light. However, in some supermarkets and shopping malls, backlighting is required for product labels, prices, and descriptions. Currently, to achieve a frameless effect on the front, frameless panel lights typically use a 4mm thick acrylic diffuser plate with grooves on all four sides, which is then embedded into an aluminum profile frame. This solution results in a thicker panel light and requires additional grooving of the diffuser plate, increasing production costs. Furthermore, when the diffuser plate is too thick, light is more scattered and absorbed as it passes through, leading to decreased light transmittance and reduced brightness, thus affecting lighting effects and luminous efficiency.
[0003] There is an urgent need to provide a grooving-free, thin diffuser plate edge panel light to achieve a frameless effect. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application proposes a borderless panel light for label backlighting.
[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:
[0006] A frameless panel light for label backlighting includes a frame, a back plate, a light guide plate, and a diffuser plate. Two sets of frames are arranged opposite each other, and each set of frames has a mounting groove along its length on one side that is close to the other. A light strip is provided at the bottom of the mounting groove. The back plate, the light guide plate, and the diffuser plate are sequentially abutted against each other, and the back plate and the diffuser plate abut against the two side walls of the mounting groove along its length. The frame has a bevel at the edge of the mounting groove opening, with the bevel located near the diffuser plate. Viewed from the mounting groove opening direction, the cross-sectional area of the frame on the side near the mounting groove opening is smaller than the cross-sectional area on the side near the bottom of the mounting groove.
[0007] Preferably, the back panel is made of a reflective material.
[0008] Preferably, the inclination angle of the inclined plane is 15°-45°.
[0009] Preferably, the inclination angle of the inclined plane is 30°.
[0010] Preferably, the frame is provided with a limiting plate at the mounting groove opening, and the limiting plate is used to abut against the side of the back plate away from the light guide plate.
[0011] Preferably, the mounting groove is a through groove along its own length direction, and an end cap is provided on the frame, the end cap being used to cover the openings on the same side of the mounting grooves of the two frames.
[0012] Preferably, the end cap is provided with a connecting plate, which is threadedly connected to the limiting plate by screws.
[0013] Preferably, a side light panel is provided on the side of the frame, and the side light panel is used to make the side of the panel light emit light.
[0014] Preferably, the side of the frame is provided with a placement groove for placing the side light panel.
[0015] Preferably, the panel light further includes a lead wire, which is provided with a quick-connect terminal and is connected to the light strip and the side light panel.
[0016] In summary, this application includes at least one of the following beneficial technical effects:
[0017] When the product label is placed on the panel light, the upper edge of the frame abuts against the product label. The light is emitted by the light strip set in the mounting groove, and the light is emitted from the diffuser plate through the light guide plate and the reflective back plate. The beveled edge of the frame reduces the contact area between the product label and the frame, guiding the light to reflect and expanding the coverage area of the emitted light, making the frame visually invisible and achieving a frameless effect. This design achieves a frameless effect through the beveled design, eliminating the need for a groove design on the side of the diffuser plate, reducing the thickness of the diffuser plate, and also enhancing the luminous effect of the panel light.

[0024] 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 scope of protection of the present utility model.
[0025] This application discloses a frameless panel light for label backlighting.
[0026] Reference Figure 1A frameless panel light for label backlighting includes a frame 1, a back plate 2, a light guide plate 3, and a diffuser plate 4. Specifically, the frame 1 is made of aluminum profile and is elongated. Two sets of frames 1 are provided, arranged parallel and spaced apart. A mounting groove 11 is provided on the side of the two sets of frames 1 that are close to each other. The mounting groove 11 has a rectangular cross-section when viewed from the opening direction and extends along the length of the frame 1. In this embodiment, to facilitate the installation of components, the mounting groove 11 is designed as a through groove, and the plane of the opening of the mounting groove 11 is perpendicular to the length direction of the mounting groove 11. A light strip 5 is installed at the bottom of the groove, and multiple sets of 4014 LED beads are installed on the light strip 5. The light emitted by the light strip 5 is emitted from the opening of the mounting groove 11. The light strip 5 can be installed in both mounting grooves 11, or only one can be installed. The back plate 2, light guide plate 3, and diffuser plate 4 are sequentially abutted, so that the back plate 2, light guide plate 3, and diffuser plate 4 are set with zero gap between them, reducing the loss of light during the propagation process and enhancing the light efficiency of the panel light. The back plate 2 and diffuser plate 4 abut against the two opposite side walls of the mounting groove 11 extending in their own direction, and the back plate 2, light guide plate 3, and diffuser plate 4 are constrained by the side walls of the mounting groove 11. The back plate 2, light guide plate 3, and diffuser plate 4 are all rectangular plates. In this embodiment, the back plate 2 is 0.6mm thick, the light guide plate 3 is 3mm thick, and the diffuser plate 4 is 1mm thick. The light guide plate 3 is used to convert the light emitted from the lamp strip 5 into a uniform surface light source. The diffuser plate 4 is used to make the light more uniform and soft when emitted, avoiding obvious light spots, shadows, or glare, and improving the comfort and aesthetics of the lighting. At the same time, the frame 1 has a bevel 12 at the edge of the mounting groove 11. The bevel 12 is located on the side close to the diffuser plate 4, and one side of the bevel 12 extends to the side of the frame 1 away from the mounting groove 11 to reduce the impact on the product. The contact area when the product label comes into contact with the frame is considered. From the direction of the groove opening of the mounting groove 11, the cross-sectional area of the frame 1 on the side near the groove opening of the mounting groove 11 is smaller than the cross-sectional area on the side near the bottom of the mounting groove 11. In this embodiment, the inclination angle of the inclined surface 12 is 15°-45°, preferably 30°. Therefore, when light is emitted from the diffuser plate 4, some light will be emitted towards the inclined surface 12. The inclined surface 12 will reflect the guiding light to expand the coverage area of the emitted light, so that the frame 1 is visually hidden, achieving an effect similar to the frameless 1. There is no need to make a groove design on the side of the diffuser plate 4, reducing the thickness of the diffuser plate 4 and enhancing the luminous effect of the panel light.
[0027] Reference Figure 1 and Figure 2In this embodiment, in order to further improve the light efficiency of the panel light, the back plate 2 is made of reflective material. So when the light emitted from the light strip 5 hits the back plate 2, the back plate 2 can reflect the light, so that the back plate 2 integrates the reflective function and the structural support function, without the need to add an additional structure. That is, the light efficiency of the panel light is enhanced without changing the thickness of the panel light.
[0028] In some embodiments, in order to improve the overall structural strength of the panel light, a limiting plate 13 is provided at the groove opening of the mounting groove 11 of the frame 1. The limiting plate 13 is integrally provided with the frame 1, and the limiting plate 13 is provided on the side edge of the groove opening of the mounting groove 11 away from the inclined surface 12. When the back plate 2 is installed in the mounting groove 11, the side of the back plate 2 away from the light guide plate 3 abuts against the limiting plate 13, increasing the contact area between the back plate 2 and the frame 1, and preventing the back plate 2 from being damaged by force.
[0029] Meanwhile, end caps 6 are also provided on the frame 1. The end caps 6 are thin plates, and there are two sets of end caps 6. The two sets of end caps 6 are respectively located on the same side of the two frames 1. The end caps 6 are used to seal the openings on both sides of the mounting groove 11. The two sets of end caps 6 are connected to the two frames 1 to form a rectangular frame. During use, this can prevent internal components from falling out of the opening of the mounting groove 11 as much as possible, and can also prevent dust from adhering to the light strip 5 during use, thus affecting the light efficiency. In addition, a connecting plate 7 is provided on the end cap 6. The connecting plate 7 is also thin plates. The connecting plate 7 is located on the lower side of the end cap 6 and is perpendicular to the end cap 6. The connecting plate 7 is used to abut against the limiting plate 13 on the two frames 1. The connecting plate 7 is connected to the limiting plate 13 by screws, so that the end cap 6 is installed on the frame 1. This enhances the structural strength and improves the fixation of the end cap 6, preventing the back plate 2, light guide plate 3, and diffuser plate 4 from falling out.
[0030] In some embodiments, a placement groove 14 is provided on the side of the frame 1 away from the groove opening of the mounting groove 11. In this embodiment, the placement groove 14 is also in the form of a through groove, and the length direction of the through groove is parallel to the length direction of the placement groove 14. A side light panel 8 is provided at the bottom of the placement groove 14. The side light panel 8 is attached to the bottom of the placement groove 14, and the panel light emits light from the side through the side light panel 8. Depending on the usage, the side light panel 8 can be provided in the placement grooves 14 of both frames 1, or the side light panel 8 can be provided in one of the placement grooves 14, so that the panel light can have the ability to provide both front main lighting and side auxiliary light output at the same time, adapting to the multi-dimensional lighting needs of supermarket shelves. At the same time, hiding the side light panel in the placement groove 14 can prevent users from being affected by the lamp beads on the side light panel when selecting goods.
[0031] In addition, the panel light also includes a wire outlet 9, which is connected to the light strip 5 and the side light panel 8 respectively. The wire outlet 9 is provided with a quick-plug terminal to facilitate power supply and control of the light strip 5 and the ambient light strip 5.
[0032] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
