LED Light Bars for SEG Fabric Lightboxes
FH Lighting supplies lens LED bars and backlight arrays for fabric lightboxes. Choose side lighting or backlighting, then match the input, lens and layout to your frame.
Start with the frame
Choose where light enters.
Side-light bars illuminate across the box from its edges. Backlight arrays sit behind the graphic. The frame depth, viewing sides and front material determine the layout.
Behind the graphic
SEG backlight arrays
Connected rigid bars spread across the rear of the lightbox. The listed SEG assembly uses 24 V DC, 36 LEDs and a 685 mm bar width.
Review Backlight Models
Longer optical spans
The 12 cm side-light series uses 7 × 25° lenses. Review the full frame and sample before using the illustrated 3 m span reference.
Tubular frame lighting
24 V DC side-light bars with 20 × 45° lenses. Confirm the frame attachment, connectors and wiring with the selected bar.
White and RGB arrays
White backlight arrays use 24 V DC; the RGB array shown uses 12 V DC. Confirm the controller, wiring and assembly load for the chosen set.
Side-light selection
Match depth, lens and span.
The spans below are illustrated layout references with light entering from opposing edges. They describe the illuminated span, not the length of an LED bar.
| Lightbox depth series | Lens angle | Illustrated maximum span |
|---|---|---|
| 6 cm | 10 × 25° | 1.2 m |
| 6 cm | 10 × 35° | 1 m |
| 8 cm | 10 × 25° | 1.2 m |
| 8 cm | 15 × 45° | 1 m |
| 8 cm | 10 × 20° | 1.2 m |
| 12 cm | 7 × 25° | 3 m |
Confirm the bar spacing, frame reflectance, graphic, diffuser and viewing conditions with a representative assembly. A span reference is not a uniformity guarantee for every lightbox.

Dimensions are length × width × height where all three are listed. The 12 V backlight bars list length × width; the SEG assembly lists bar width only. White-light color temperature, connectors, control and mounting parts are confirmed for the selected order.
Specify the supplied set.
Order LED bars or connected arrays separately. The frame, printed fabric, power supply, controller, cables and mounting parts are included only when listed in the quotation. Quantity, sample schedule and packing are confirmed for the selected configuration.
Before ordering
Lightbox LED strip questions
Can I order only the LED bars or array?
Yes. FH Lighting can quote the lighting components separately. Specify the model or lighting layout and confirm whether connectors, mounting parts, power supply or a controller are required.
Should I choose side lighting or backlighting?
Side-light bars send light across the box from its edges. Backlight arrays distribute bars behind the graphic. Send the illuminated width and height, frame depth, viewing sides and front material so the layout can be reviewed.
Do all models use the same power supply?
No. The listed ranges include 12 V DC, 24 V DC and a selected 100–240 V AC model. Match the power input, total load, connectors and control to the exact reference; an AC-input bar is not interchangeable with a DC bar.
How do these bars differ from a light guide panel?
These bars illuminate the lightbox directly from its edges or rear. A light guide panel uses a patterned PMMA optical plate. They are separate supply choices; select the optical structure before choosing the LEDs.
Drawing and model review
Send the frame size, depth and quantity.
Include the preferred model, single- or double-sided layout, light color, input voltage, control needs and destination. FH Lighting will review the bar arrangement and supplied parts.
