Backlit LED Curtain 2835 SMD with Lens
Backlit LED curtain is a modular LED backlighting solution designed for super thin light boxes, advertising displays, SEG fabric light boxes, exhibition displays, retail signage and architectural lighting. It uses 2835 SMD LED chips with PMMA high-efficiency lens to create bright, soft and uniform illumination behind translucent materials.
Compared with traditional lighting systems, this LED curtain provides low power consumption, stable brightness, flexible layout and easy installation. The lens design helps spread light widely, reducing hotspots and shadows for commercial display and decorative backlighting projects.

Why Choose Backlit LED Curtain?
Uniform Backlighting for Thin Light Boxes
The wide beam angle and lens-based design help distribute light evenly across the backlit surface. This makes the LED curtain suitable for super thin light boxes, advertising frames and fabric display systems where uniform brightness is important.
High-efficiency PMMA Lens
The PMMA optical lens improves light diffusion and helps reduce visible hotspots. It is useful for translucent fabric, acrylic panels, signage surfaces and other display materials that need soft and consistent illumination.
Constant Current and Stable Brightness
The constant current design helps maintain stable brightness and improves lighting reliability. With conversion efficiency above 95%, the backlit LED curtain supports long-term commercial use with lower energy consumption.
Flexible Layout for Custom Sizes
The LED strip quantity, strip distance and final layout can be adjusted according to the size, brightness requirement and depth of the light box. This gives B2B buyers more flexibility for custom projects.
Applications of Backlit LED Curtain
Super thin LED light boxes
SEG fabric light boxes
Advertising display frames
Retail signage and menu boards
Exhibition and trade show displays
Stage backgrounds and decorative panels
Architectural lighting and translucent wall panels
How to Design a Backlit LED Curtain Layout
Confirm Light Box Depth
The thinnest suitable profile for this LED curtain is about 40mm. If the profile is thicker than 40mm, the light uniformity is usually better because the light has more distance to spread evenly.
Confirm Strip Distance and Brightness Target
The layout, strip quantity and distance depend on the final light box size and brightness requirement. Smaller LED strip distance usually creates brighter and more uniform backlighting.
Choose Cable or Screw Connection
The product can be connected by cable or screws depending on the frame structure and installation needs. Buyers should confirm wiring direction, power supply location and maintenance method before production.

Frequently Asked Questions
Can the backlit LED curtain be cut?
Yes. The LED curtain can be cut every 3 LEDs. Cutting should be done only at the marked cutting positions to keep the circuit stable.
Can you print our logo or brand on the PCB?
Yes. Wallis can print your logo or brand onto the PCBs. Please confirm the logo 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 per light box?
The LED strip layout, size and quantity depend on the final light box size and brightness requirement. A smaller distance between LED strips usually creates a brighter light box.
Is this backlit LED curtain suitable for SEG fabric light boxes?
Yes. It is suitable for SEG fabric light boxes, advertising light boxes and translucent display systems that need uniform backlighting and a thin frame structure.
What certifications does this LED curtain have?
This backlit LED curtain is CE and RoHS certified and designed to comply with international safety standards for commercial LED lighting applications.
