LED Ladder Back Light for Light Box and Signage

LED ladder back light is a high-efficiency backlighting system for light boxes, signage displays, LCD displays, advertising panels and commercial illuminated structures. It uses multiple LED strips arranged in a ladder-like layout behind the lighting surface, helping deliver uniform brightness, strong luminous output and energy-saving performance.

Compared with traditional LED strip layouts, the ladder backlight design makes installation more organized and helps reduce shadows, dark areas and uneven brightness. It is suitable for digital signage, advertising displays, TV-style backlight systems, large light boxes and custom LED curtain lighting projects.

Key Features of LED Ladder Back Light

1. SMD2835 LED chip for stable brightness and efficient performance.

2. Energy-saving LED lighting strip for commercial backlighting.

3. Constant current design with conversion efficiency above 95%.

4. Uniform brightness for light boxes and display panels.

5. Complies with international safety standards.

6. PMMA high-efficiency lens for improved light distribution.

7. DC24–30V wide voltage input with stable brightness output.

8. CE, RoHS and UL certified.

9. Warranty: 2 years.

10. The thinnest LED frame can be 40mm, with 80mm distance between LED strips.

Why Choose LED Ladder Back Light?

Uniform Brightness for Light Boxes

The ladder-style LED layout helps create even illumination across the whole lighting surface. The distance between LED strips can be adjusted according to the depth of the profile, helping achieve better light uniformity and reduce visible shadows.

High Efficiency 2835 LED Chip

The 2835 LED chip supports stable luminous output and energy-saving performance. It is suitable for long-term commercial lighting applications where brightness, efficiency and reliability are important.

Flexible Cutting and Connection

The minimum cutting size is 170mm with 3 LEDs. Different pieces can be connected by soldering cables or plastic connectors, making it easier to build customized lighting curtains for different light box sizes.

Custom Color Temperature and Brightness

Different color temperatures are available, including 3000K, 4000K, 4500K and 6000K. Wallis can also support custom sizes, brightness requirements and logo printing for project-based orders.

Applications of LED Ladder Back Light

• Advertising light boxes

• Signage backlighting

• Digital signage displays

• LCD screen and TV-style backlight systems

• Retail display panels

• Menu boards and logo light boxes

• Custom LED curtain lighting projects

How to Design LED Ladder Back Light Layout

Confirm Profile Depth

To achieve the best lighting effect, the distance between LED strips should be adjusted based on the depth of the profile. The thinnest suitable profile for this LED curtain is about 40mm, and the uniformity will be better when the profile is thicker than 40mm.

Confirm Light Box Size and Brightness Target

The number of LED strips depends on the final light box size, required brightness and installation depth. A smaller distance between LED strips usually creates a brighter and more uniform light box.

Choose Cable or Connector Assembly

Connection can be made by soldering cables or using plastic connectors. Buyers should confirm installation method, wiring direction, power supply position and maintenance requirements before production.

Custom LED Ladder Back Light Service

Wallis supports custom LED ladder back light projects, including logo printing, different PCB sizes, custom brightness, different color temperatures, special connection methods and light box layout recommendations.

For custom projects, buyers can provide final light box size, profile depth, brightness target, color temperature, voltage, connection method and order quantity. Wallis can assist with suitable LED strip layout and production suggestions.

Conclusion

LED ladder back light is a reliable backlighting solution for light boxes, signage displays, digital signage, retail panels and custom LED curtain systems. With 2835 LED chips, PMMA high-efficiency lens, constant current design, DC24–30V wide voltage input, 170° beam angle and flexible connection options, it provides stable brightness and efficient light distribution.

For B2B buyers looking for custom LED ladder back light suppliers, Wallis can support sample testing, logo printing, layout design, connector assembly and project-based production according to light box size and brightness requirements.

Frequently Asked Questions

Can the LED ladder back light be cut?

Yes. It can be cut every 3 LEDs, and the minimum cutting size is about 170mm. Cutting should be done at the correct position to protect the circuit and maintain stable performance.

Can you print our logo or brand on the PCB?

Yes. Wallis can print your logo or brand onto the PCB. For logo printing orders, please confirm artwork and order quantity before production.

What is the thinnest profile suitable for this LED curtain?

The thinnest suitable profile is about 40mm. If the profile is thicker than 40mm, the light uniformity will usually be better.

How many LED strips should be installed in one light box?

The LED strip quantity and layout depend on the final light box size, profile depth and brightness requirement. A smaller distance between LED strips usually creates a brighter and more uniform light box.

What is the MOQ for LED ladder back light?

Wallis can support sample testing before final orders. With logo printing, the MOQ is usually 100 pieces. Without logo printing, the MOQ for standard type is usually 10 pieces.

Where is your shipping port?

Wallis is located in Shanghai, and the nearest sea port is Shanghai Port. Ningbo and Shenzhen ports are also possible depending on shipping arrangements.
