Features of Side Emitting LED Light Bar
1. Compact Side Emitting Design for Slim Light Boxes
Designed for edge-mounted installation, this compact LED light bar provides efficient side illumination for slim advertising light boxes, producing bright and even lighting while maximizing the usable display area.
2. Two Brightness Options for Different Projects
Available in both SMD2835 (12W) and SMD3030 (18W) versions, allowing customers to select the ideal balance between energy efficiency and higher luminous output based on project requirements.
3. Precision Optical Lens for Uniform Illumination
Each LED is equipped with a specially designed optical lens that directs light deep into the light box, improving light distribution and reducing visible hotspots and dark areas.
4. High-Efficiency Aluminum PCB Construction
The rigid aluminum PCB offers excellent thermal conductivity for stable performance, efficient heat dissipation and a longer operating lifespan in continuous commercial applications.

What Thickness & Length Are Ideal For Backlit LED Light Boxes?

Wondering how to choose the perfect dimension match for your backlit advertising light boxes with our side-emitting LED hard strips?
This diagram illustrates the scientific matching relationship between light box thickness (Y-axis, D) and overall light box length (X-axis, L).
The shaded area marks the most applicable size range for this side emitting LED bars:
✅ Suitable light box length: 1000mm – 3000mm
✅ Recommended cabinet thickness: 80mm – 300mm

Core Optical Design Principle
We follow the optical performance ratio: Light Box Thickness(D) : Light Box Length(L) ≥ 1:15
This ratio is the key to even, flicker-free illumination across the entire light box surface.
Longer light boxes require thicker cabinets to ensure sufficient light diffusion and eliminate strip shadows & dark areas;
The D/L ratio directly determines the lighting uniformity performance of our lens-based side-emitting LED light bars;
Larger-size light boxes deliver broader light diffusion spots for seamless backlighting effects.
Sticking to this dimension standard helps you get flawless uniform brightness for indoor & outdoor signage light boxes.
