Features of Diffused LED Backlight Bar
1. Innovative Plug-in Connection for Faster Installation
The DF90 Series features an innovative plug-in terminal connection system, allowing each LED bar to be inserted directly into the terminal connection board without complicated wiring. This modular design significantly shortens installation time while making maintenance and replacement faster and more convenient for commercial light box manufacturers.
2. Single LED Cuttable for Maximum Design Flexibility
Each SMD2835 LED can be cut individually, allowing installers to easily customize the lighting layout for light boxes of different sizes and shapes. Whether producing standard advertising displays or custom signage, the DF90 Series provides outstanding flexibility while reducing material waste.
3. Aluminum PCB for Superior Heat Dissipation
Each LED bar is manufactured using a durable aluminum PCB, offering excellent thermal conductivity and improved heat dissipation. This helps maintain stable luminous output, extends LED lifespan and ensures reliable performance in continuous commercial applications.
4. Flexible Modular System for Custom Light Boxes
The modular plug-in structure allows terminal connection boards to be installed at selected intervals, enabling quick assembly of light boxes in various dimensions. This design simplifies production while improving installation efficiency for signage manufacturers and lighting contractors.

Diffused LED Backlight Bar Wiring Diagram & Installation Guide
1. The outlet wire of the diffuse reflection terminal connect board is 18AWG, and the Max current is 10A;
2. When the terminal connect board of diffuse reflection has a single outlet connected to the power supply (DC12V), a maximum of 10PCS LED bar with 10LED can be connected;
Recommended Applications for Diffused LED Backlight Bar
1. Single-Sided Advertising Light Boxes
Designed specifically for single-sided illuminated light boxes, the DF90 Series delivers uniform backlighting with high brightness and easy installation. The plug-in design reduces assembly time while ensuring consistent illumination across the advertising surface.
2. Sign Letter Backlighting
Suitable for 4–15 cm sign letters, the compact LED bars provide bright and evenly distributed illumination inside channel letters and illuminated signage, creating clear visibility for retail stores and commercial branding.
3. Transportation Advertising Systems
4. Custom Light Box Manufacturing
