- Easy module replacement during maintenance without rewiring the full system
- Compatible with standard DC24V light box wiring harnesses
Why Choose Modular LED Backlighting?
| Traditional LED Installation | Modular DC Plug System |
|---|---|
| Complex wiring and soldering | Simple plug-in connection |
| Difficult to reconfigure | Flexible layout adjustment |
| Time-consuming maintenance | Fast module swap — no rewiring |
| Fixed length constraints | Mix 3-LED, 6-LED, 9-LED as needed |
Modular Length Options for Different Light Box Sizes
Available in 143mm (3-LED), 270.5mm (6-LED), and 398mm (9-LED) versions. Select the suitable module length according to your light box dimensions — or mix lengths within the same installation to achieve precise coverage without gaps or overlap.
- 3-LED / 143mm — Compact sections, corners, and narrow frame areas
- 6-LED / 270.5mm — Mid-size panels and standard display frames
- 9-LED / 398mm — Large format light boxes requiring higher output per module
Designed for Advertising Light Box Manufacturing
Purpose-built for the commercial display industry. This modular backlight bar is used by light box manufacturers, display integrators, and signage installers who need reliable, consistent backlighting with efficient installation workflows.
- Advertising light boxes — indoor and outdoor
- SEG fabric display systems
- Retail illuminated signage and POP displays
- Exhibition and trade show backlit walls
- Custom signage and display frame structures
Multiple Color Temperature Options
Available in four color temperature selections to match different display requirements. Select the CCT that best suits your display environment — warm white for retail ambiance, natural white for general commercial use, or cool daylight for high-contrast graphic displays.
- 2800–3200K — Warm White: retail, hospitality, and lifestyle displays
- 3700–4300K — Natural White: general commercial and office environments
- 4700–5300K — Neutral Daylight: balanced output for mixed environments
- 6500–7000K — Cool Daylight: high-contrast graphics and exhibition displays
When Should You Use Modular DC Plug LED Bars?
- Production Efficiency: When your team installs multiple light boxes per day, plug-in connections reduce per-unit assembly time compared to hardwired systems.
- Field Maintenance: When a module fails in an installed display, DC plug modules can be swapped without rewiring — reducing downtime and service costs.
- Custom Light Box Builds: When standard fixed-length bars don't match your frame dimensions, mixing 3-LED, 6-LED, and 9-LED modules gives you precise coverage control.
- Retrofit Installations: When upgrading existing displays, modular plug-in bars integrate into existing DC24V wiring without custom hardware.
CE & RoHS Certified
