Description

Technical Field

[0001] This utility model relates to the field of hanging light box technology, and in particular to a five-sided hanging light box with uniform brightness. Background Technology

[0002] The five-sided hanging light box is a three-dimensional lighting device that adopts a modular design and achieves 360° omnidirectional uniform light emission. Its main body is composed of a high-transmittance acrylic light guide plate and a precision optical film layer. This device breaks through the unidirectional lighting limitation of traditional flat light boxes and forms an immersive light environment without visual blind spots.

[0003] Traditional five-sided hanging light boxes have significant shortcomings in terms of lighting uniformity, mainly manifested in dark areas at the four corners, affecting the overall visual effect. In existing technologies, conventional five-sided hanging light boxes mostly use flat reflective films, and light-emitting components (such as LED light strips) are usually concentrated at the top or sides of the light box, resulting in a typical light distribution with a "bright center and dark edges" characteristic. Especially at the four corners of the light box, due to the long light propagation path and lack of effective control, some light cannot reach the edge areas due to scattering loss or reflection blind spots, ultimately forming obvious dark area defects. This problem is particularly prominent in scenarios that require high uniformity of lighting, such as shopping mall hanging displays, airport wayfinding signage, and special exhibition booths, directly affecting the advertising display effect, information transmission clarity, and spatial visual comfort.

[0004] Therefore, to address the issue of dark areas in the four corners of traditional light boxes when used in scenarios requiring high uniformity lighting, a five-sided suspended light box with uniform brightness can be designed. When in use, the five-sided suspended light box is first suspended and fixed by a hanging mechanism. When powered by an external power source, the light-emitting components emit light individually. The light is reflected, refracted, and diffused multiple times by the microprism structure of the reflective film. The special optical design of the microprisms allows for precise control of the light, dispersing the light, originally concentrated in the center, evenly to all areas within the lampshade cavity, including the dark areas in the four corners and the bottom edge that are common in traditional light boxes. The high light transmittance of the acrylic material and the secondary reflection effect of the reflective coating on the inner wall further improve the utilization rate and uniformity of light distribution, ultimately creating a lighting effect with no dark areas and consistent brightness. In summary, this design effectively solves the problem of dark areas in the four corners of traditional light boxes through the synergistic effect of the microprism structure of the reflective film and the reflective coating, achieving uniform light emission from all five sides and improving the overall lighting uniformity. Utility Model Content

[0005] Conventional five-sided hanging light boxes mostly use flat reflective films, and the light-emitting components are usually concentrated on the top or side of the light box, resulting in a light distribution that is "bright in the center and dark at the edges". Therefore, when used in scenarios that require high uniformity of lighting, it is inconvenient to solve the problem of dark areas in the four corners of traditional light boxes.

[0006] The technical solution of this utility model is as follows: a five-sided hanging light box with uniform brightness, including a lampshade, a hanging assembly above the lampshade, a lamp tube inside the lampshade, and multiple sets of reflective films. The inner wall of the lampshade is provided with a reflective film, and the surface of the reflective film has a microprism structure. Multiple sets of microprism structures are evenly arranged, and a light-emitting component is provided inside the lampshade.

[0007] Preferably, when the five-sided hanging lightbox is in use, the entire structure is first suspended and fixed by the hanging mechanism. When the external power supply is activated, the light-emitting components emit light individually. The light is reflected, refracted, and diffused multiple times by the microprism structure of the reflective film. The special optical design of the microprisms allows for precise control of the light, so that the light originally concentrated in the center is evenly distributed to all areas of the lampshade cavity, including the dark areas at the four corners and the bottom edge that are common in traditional lightboxes. The high light transmittance of the acrylic material and the secondary reflection effect of the reflective coating on the inner wall further improve the utilization rate and uniformity of light distribution, ultimately forming a lighting effect with no dark areas and uniform brightness. In summary, this design effectively solves the problem of dark areas at the four corners of traditional lightboxes through the synergistic effect of the microprism structure of the reflective film and the reflective coating, achieving uniform light emission from all five sides and improving the overall lighting uniformity.

[0008] Preferably, multiple sets of reflective films are respectively disposed on the inner walls around the lampshade cavity and the bottom wall of the inner cavity, and the top of the lamp tube is connected to the hanging assembly.

[0009] Preferably, the light-emitting component includes a mounting column, a light-emitting tube, and a light-emitting strip; light-emitting tubes are installed at the corners of the inner cavity of the lamp cover, mounting columns are installed around the inner cavity of the lamp cover, and multiple sets of light-emitting strips are installed on the outer circumference of the lamp tube.

[0010] Preferably, multiple sets of light strips are arranged in a circular array, and the light tubes are installed inside the mounting column. The top of the mounting column is fixedly connected to the top wall of the inner cavity of the lamp cover.

[0011] Preferably, the hanging assembly includes a hanging top bracket, a hanging column, and a hanging base; the hanging base is provided on the top of the lampshade, the hanging column is fixedly provided above the hanging base, and the hanging top bracket is fixedly provided at the top of the hanging column; the hanging base is connected to the top of the lampshade by screws.

[0012] Preferably, the lampshade is made of transparent acrylic material, and the inner surface of the lampshade is coated with a reflective coating.

[0013] The beneficial effects of this utility model are: 1. When the five-sided hanging lightbox is in use, it is first suspended and fixed by the hanging mechanism. When the external power supply is applied, the light-emitting components emit light. The light is reflected, refracted, and diffused multiple times by the microprism structure of the reflective film. The special optical design of the microprism can precisely control the light, so that the light originally concentrated in the center is evenly distributed to all areas of the lampshade cavity, including the dark areas in the four corners and the bottom edge that are common in traditional lightboxes. The high light transmittance of the acrylic material and the secondary reflection effect of the reflective coating on the inner wall further improve the utilization rate and distribution uniformity of the light, ultimately forming a lighting effect with no dark areas and uniform brightness. In summary, this design effectively solves the problem of dark areas in the four corners of traditional lightboxes through the synergistic effect of the microprism structure of the reflective film and the reflective coating, realizes uniform light emission from all five sides, and improves the overall lighting uniformity.

[0014] 2. Firstly, the combination of acrylic transparent lampshade and reflective coating ensures high light transmittance while reducing light loss through secondary reflection, achieving energy saving and environmental protection. Secondly, the hanging components adopt a split structure, which is convenient, stable and reliable for installation. Thirdly, the layout of the light-emitting components is optimized: such as the lamp tubes being located at the corners and the light strips being arranged in a circular array, combined with the optical control of the reflective film, making the light distribution more scientific and reasonable, which not only enhances the brightness of the center but also eliminates the dark areas at the edges, resulting in a better overall visual effect. It is suitable for places such as shopping malls and exhibition halls where high brightness uniformity is required. Attached Figure Description

The reflective film 3 is provided on the inner wall of the lampshade 1 and the surface of the reflective film 3 has a microprism structure. Multiple sets of microprism structures are evenly arranged, and a light-emitting component is provided inside the lampshade 1.

[0018] Please see Figure 2 and Figure 4 Multiple sets of reflective films 3 are respectively set on the inner walls of the lampshade 1 around the perimeter and the bottom wall of the inner cavity. The top of the lamp tube 2 is connected to the hanging assembly. The light is reflected, refracted and diffused multiple times by the microprism structure of the reflective film 3. The special optical design of the microprism can precisely control the light. The light-emitting component includes a mounting column 4, a light-emitting tube 5 and a light-emitting strip 6. Light-emitting tubes 5 are set at the corners of the inner cavity of the lampshade 1. Mounting columns 4 are set around the perimeter of the inner cavity of the lampshade 1. Multiple sets of light-emitting strips 6 are set on the outer periphery of the lamp tube 2. When the external power supply is provided, the light-emitting tubes 5 and the light-emitting strips 6 emit light respectively. The multiple sets of light-emitting strips 6 are distributed in a circumferential array. The light-emitting tubes 5 are set inside the mounting columns 4. The top of the mounting columns 4 is fixedly connected to the top wall of the inner cavity of the lampshade 1. When the external power supply is provided, the light-emitting tubes 5 and the light-emitting strips 6 emit light respectively.

[0019] Please see Figure 1 and Figure 3 The hanging assembly includes a hanging top bracket 7, a hanging column 8, and a hanging base 9. The hanging base 9 is installed on the top of the lampshade 1, and the hanging column 8 is fixedly installed above the hanging base 9. The hanging top bracket 7 is fixedly installed on the top of the hanging column 8. The hanging base 9 is connected to the top of the lampshade 1 by screws. During installation, the hanging top bracket 7 is first fixed in the pre-installation position, the hanging column 8 connects the top bracket and the base, and the base is locked to the top of the lampshade 1 by screws to complete the overall suspension and fixation. The lampshade 1 is made of transparent acrylic material, and the inner surface of the lampshade 1 is coated with a reflective coating. The combination of the transparent acrylic lampshade 1 and the reflective coating not only ensures high light transmittance, but also reduces light loss through secondary reflection, achieving the purpose of energy saving and environmental protection.

[0020] When the five-sided hanging light box is in use, the uniformly bright five-sided hanging light box achieves uniform light emission through the collaboration of multiple components. The hanging components consist of a hanging top bracket 7, a hanging column 8, and a hanging base 9. During installation, the hanging top bracket 7 is first fixed in the pre-installation position, the hanging column 8 connects the top bracket and the base, and the base is locked to the top of the lampshade 1 with screws to complete the overall suspension and fixation.

[0021] The lampshade 1 is made of transparent acrylic material, with a reflective coating on the inner surface. The inner wall and bottom wall are all equipped with reflective films 3 with microprism structures. The light-emitting components include mounting columns 4, light tubes 5 and light strips 6. The mounting columns 4 are distributed around the inner cavity of the lampshade 1, and the top is fixed to the top wall. The light tubes 5 are embedded inside. Multiple sets of light strips 6 are arranged in a circular array on the outer periphery of the lamp tube 2. The top of the lamp tube 2 is connected to the hanging components.

[0022] When powered by an external power source, the light tube 5 and the light strip 6 emit light respectively. The light is reflected, refracted and diffused multiple times by the microprism structure of the reflective film 3. The special optical design of the microprism can precisely control the light, so that the light originally concentrated in the center is evenly distributed to all areas of the inner cavity of the lampshade 1, including the dark areas in the four corners and the bottom edge that are prone to occur in traditional light boxes. The high light transmittance of the acrylic material and the secondary reflection effect of the reflective coating on the inner wall further improve the utilization rate and distribution uniformity of the light, ultimately forming a lighting effect with no dark areas and uniform brightness.

[0023] In summary, firstly, this design effectively solves the problem of dark areas in the four corners of traditional light boxes by using the synergistic effect of the microprism structure of the reflective film 3 and the reflective coating, achieving uniform light emission from all five sides and improving the overall lighting uniformity. Secondly, the combination of the acrylic transparent lampshade 1 and the reflective coating ensures high light transmittance while reducing light loss through secondary reflection, achieving energy saving and environmental protection. Thirdly, the hanging components adopt a split structure, which is convenient, stable and reliable for installation. Fourthly, the layout of the light-emitting components is optimized: such as the lamp tubes being located at the corners and the light strips being arranged in a circular array, combined with the optical control of the reflective film 3, the light distribution is more scientific and reasonable, which not only enhances the brightness of the center but also eliminates the dark areas at the edges, resulting in a better overall visual effect. It is suitable for places with high requirements for brightness uniformity, such as shopping malls and exhibition halls.

[0024] Through the above steps, when the five-sided hanging lightbox is in use, the entire structure is first suspended and fixed by the hanging mechanism. When the external power supply is applied, the light-emitting components emit light. The light is reflected, refracted, and diffused multiple times by the microprism structure of the reflective film 3. The special optical design of the microprism can precisely control the light, so that the light originally concentrated in the center is evenly distributed to all areas of the inner cavity of the lampshade 1, including the dark areas in the four corners and the bottom edge that are prone to occur in traditional lightboxes. The high light transmittance of the acrylic material and the secondary reflection effect of the reflective coating on the inner wall further improve the utilization rate and distribution uniformity of the light, ultimately forming a lighting effect with no dark areas and uniform brightness. In summary, this design effectively solves the problem of dark areas in the four corners of traditional lightboxes through the synergistic effect of the microprism structure of the reflective film 3 and the reflective coating, achieving uniform light emission from all five sides and improving the overall lighting uniformity.
