What is an edge lighting box?

An edge lighting box is a type of lightbox that uses side-lit lighting technology. Its core feature is that the light source is located on both sides of the lightbox frame rather than at the back. Light is projected onto the image from the sides, and through the refraction and reflection of lenses, the entire surface of the lightbox emits light. This achieves uniform light distribution, ensuring that every part of the image is adequately illuminated, thereby producing a clear and even image effect. This design makes the lightbox appear more three-dimensional and eye-catching.

Особенности:

Easy installation and maintenance: The design of the edge lighting box makes installing and replacing light panels easier and faster. Wiring is relatively simple, making the installation process straightforward and hassle-free. The simple wiring also facilitates maintenance in the long term.

Diverse design: Side-lit light boxes can be customized according to specific needs, designed in various shapes, sizes, and colors to meet merchants’ personalized promotional requirements. This flexibility allows side-lit light boxes to perform optimally in various settings.

High durability: Modern side-lit light boxes typically use high-quality materials that have undergone special treatment, offering strong weather resistance and durability, enabling long-term use in various environments.

What are the types of side-lit light boxes?

Side-lit light boxes are divided into two main categories: one type uses light guides for side lighting, achieving uniform light diffusion through light guides or optical design. These light boxes feature uniform lighting and ultra-thin profiles and are designed for indoor use, making them suitable for small indoor light boxes.

The other category uses LED strip side-lit light boxes, which employ high-power LED strips on both sides combined with special lenses for light emission. These lenses are typically designed with a smaller angle, enabling illumination over a longer distance, capable of lighting up light boxes up to 3 meters away.

Edge-lit light boxes are widely used in various applications requiring enhanced visual effects, such as commercial advertising, signage, and exhibition displays. Their unique lighting method attracts more attention and enhances the overall visual impact of the advertisement.

Light guide plate side-lit light box

LED light strips are installed inside the side frames of the lightbox rather than on the back, as in traditional lightboxes. Light enters the light guide plate from the side and is refracted and scattered through evenly distributed small dots on the plate to achieve uniform illumination across the entire image. An additional PC diffusion plate on the outer surface provides secondary light diffusion, similar to the effect of a computer display screen, offering a wide light coverage area without the glare of direct light sources.

Light boxes with side-lit light guides typically have a thickness of 1–3 centimeters, significantly saving space and offering flexible installation. The light is uniform and soft, providing high visual comfort suitable for prolonged viewing. It is approximately one-tenth the thickness of a standard lightbox.

As a result, it maximizes space utilization, enhances the environment, reduces transportation costs, simplifies installation procedures, and expands application scope. Especially in environments with stringent space requirements, such as elevators, public corridors, shopping malls, supermarkets, subways, and stations, ultra-thin light boxes are the ideal choice. Compared to other light boxes, light guide plate light boxes have higher costs and are more suitable for small-sized light boxes.

Edge-lit lightbox

Edge-lit lightboxes feature LED strips installed on both sides of the frame. These lights illuminate from the sides, and during installation, the LED strips can be arranged vertically to create vertical lighting effects, horizontally to create horizontal lighting effects, or vertically and horizontally simultaneously to create lighting effects on all four sides. The light passes through the semi-transparent film behind the graphic, indirectly illuminating the lightbox advertisement and making the graphic appear more vibrant and colorful.

Edge-lit light boxes can also be made thinner. This is because the LED lights on the sides of the box enable the design of ultra-thin frames. Edge-lit LED light boxes are typically more cost-effective because they require fewer LED strips to achieve full illumination. A drawback is that this lighting method may cause slight glare on the corners and sides of the lightbox display.

Edge-lit light boxes typically only require 2 LED strips or a maximum of 4 LED strips, unlike backlit light boxes that may use dozens of LED strips. This eliminates the complexity of wiring, making the installation process simpler and more straightforward, significantly reducing labor costs. Due to their relatively simple structure, maintenance is also more convenient.

Additionally, LED light strips are directly installed on the aluminum strips of the lightbox, which facilitates heat dissipation and ensures more stable operation. The size of the light also affects how it spreads across the frame. The size of the edge-lit lightbox determines the distance of the LED lights from the center. In larger boxes, the LED lights are typically farther from the center, resulting in a dimmer appearance.

Advantages of Edge-Lit Light Boxes

Экономически эффективный: LED side lighting is applied to advertising light boxes, requiring installation only on the left and right or top and bottom sides of the box. This setup uses a minimal number of light strips, making installation simple and significantly reducing labor and material costs.

Optimal Display Performance: LED side lighting employs optical lenses designed to mimic the human pupil, altering the physical emission angle of the LEDs to project light over a greater distance, thereby achieving superior display quality.

Long Service Life: LED side lighting uses high-power LED chips, typically in 3030 or 3535 packaging with a power rating of approximately 3-5W. These chips offer high power and high luminous efficiency, and most are sourced from well-known brands such as Cree, Osram, and Philips. The 3030 or 3535 packaging uses ceramic body heat dissipation, and the side-emitting heat dissipation structure is excellent. The light board is directly fixed to the aluminum frame, allowing heat from the light board to be promptly dissipated through the aluminum frame, ensuring more stable operation of the LED chips. Continuous operation light decay is ≤5%, with a lifespan exceeding 30,000 hours.

Простой Maintenance: Compared to other LED products, LED side lighting has simple wiring and uses a constant current power supply, ensuring stable current output even with unstable voltage, resulting in very low failure rates. This effectively reduces maintenance frequency and costs.

Высокий Cost-Effectiveness: Compared to traditional backlighting, LED side lighting offers unmatched advantages in terms of installation, wiring, energy efficiency, and cost.

Гибкий Сizing: Edge-lit light boxes offer flexible sizing, capable of accommodating both small and large dimensions. They can essentially meet the sizing requirements of most light boxes.

Applications of Edge-Lit Light Boxes

Edge-lit light boxes (i.e., side-lit light boxes) offer significant advantages in commercial and outdoor applications. Their application environments include:

1. Store aреклама: Double-sided light boxes placed in trendy stores and tea shops can attract customers from both sides, serving as photo spots or visual guides. Installed on the walls of cocktail bars, they combine guidance functions with atmosphere creation to avoid visual fatigue.

2. Transparent display cabinet lighting: In jewelry stores and luxury goods counters, two-sided light boxes are used in central display cabinets to eliminate shadows with opposing light sources, highlighting the three-dimensionality and details of the products.

3. Brand identity reinforcement: Column-mounted double-sided light boxes in mall atriums or store entrances display brand logos or promotional information from all angles, enhancing nighttime visibility.

4. Platform double-sided advertising signs: Bus stop and subway passageway fabric light boxes use opposing light sources to ensure uniform brightness on both sides, suitable for outdoor rolling displays of route maps or commercial advertisements.

5. Outdoor column advertising: Community bulletin boards, highway billboards, and other thick (≥8 cm) double-sided structures use high-power side-emitting light strips to achieve long-distance visibility.

6. Art exhibit lighting: Transparent display cases or art installations in museums, using opposing light sources to eliminate single-sided projections and uniformly present artifact details.

7. High-end commercial spaces: Decorative partitions or wall light boxes in luxury stores and hotel lobbies, paired with amber-colored lighting effects to create a premium atmosphere (e.g., the “liquid ambiance” design in the Hennessy flagship store).

8. Ring-shaped exhibition stand core: Central column light boxes in ring-shaped exhibition stands at trade fairs, with dual-sided lighting to ensure visibility from all angles.

9. Wayfinding system upgrades: Double-layered 3D wayfinding signs in hospital and mall atriums, with opposing light sources to enhance readability in dim environments.

10. Customized hidden lighting: Hidden light strips along cabinet edges and beneath bar counters achieve a “light visible, source invisible” effect through side-emitting illumination.

In summary, edge light boxes have widespread applications and can be effectively utilized for advertising in retail stores, car dealerships, shopping centers, museums, transit stations, information centers, grocery stores, airports, and other similar locations!

How should I choose a lightbox?

● Light uniformity: This is an important factor to consider, especially if your lightbox is placed in an area with insufficient lighting. Backlit lightboxes typically offer better uniformity than their counterparts—light is usually distributed evenly across the surface of the graphic. If you have high requirements for light uniformity, you can opt for a backlit lightbox; if you need double-sided illumination at an economical price, we recommend choosing an edge-lit lightbox.

● Usage environment: If you are looking for a smooth, flat appearance, a light guide plate-lit lightbox is the best choice. This type of lightbox transmits light sideways. Therefore, their depth can be less than 1 inch. Light guide plate lightboxes offer excellent visual effects and help your graphics stand out! This single-sided illuminated lightbox is made from high-quality, lightweight, and durable aluminum construction, ensuring longevity and helping to withstand regular use in commercial or high-impact environments.

If there is more space behind your graphics, you can choose a backlit lightbox or a side-lit lightbox. This is because these boxes require 2-4 inches of space between the LED and the graphics to achieve uniform light diffusion. Bright lighting and clear graphics easily capture the attention of potential customers.

● Material quality: Cheap LEDs degrade rapidly over time and may lose half their brightness within the first year of operation! We recommend using high-quality or branded LEDs for a longer lifespan; the quality of the aluminum panels is also crucial. For example, polished aluminum or anodized aluminum is prone to scratches and marks, so it’s best to use electrocoated extruded aluminum for superior surface protection!

● Цена: When selecting a lightbox, you must also consider the financial impact. Backlit lightboxes are often expensive because they require more LED lights to illuminate the graphic display, which consumes more energy. Edge-lit lightboxes, however, only need a few LED lights to illuminate and are easy to install, making them more cost-effective. This lighting offers strong dual-sided illumination and installation flexibility, allowing it to stand out in any environment.
