Features of YS-MB5321 LED Sign Module
1. Two-LED SMD2835 Configuration for Higher Module Output
The YS-MB5321 2-LED SMD2835 sign module integrates two LEDs into one compact unit and delivers approximately 140 lm from 1W. Compared with single-LED modules, the two-LED configuration provides a higher output per installation point, giving sign manufacturers more flexibility when planning module quantity and spacing.
2. 140 lm/W High-Efficiency LED Performance
The module achieves up to 140 lm/W luminous efficacy, combining useful light output with controlled power consumption. This makes the MB5321 a practical option for commercial signage that operates for extended periods and where the total electrical load needs to be considered during system design.
3. 175° Wide-Angle Optical Distribution
A 175° beam angle allows light to spread broadly inside the illuminated structure instead of remaining concentrated around each LED position. This broad distribution helps support smoother brightness across the sign face and can reduce obvious hotspots when the module spacing is properly designed.
4. Constant-Current Design for Stable Lighting
The integrated constant-current design helps maintain consistent LED output across connected modules. This is particularly important in signage systems where multiple modules are installed together and a visible difference in brightness between different sections of the sign is undesirable.

YS-MB5321 LED Sign Module Layout Density Guidelines
These factory-tested layout density guidelines are engineered specifically for our YS-MB5321 high-efficiency LED sign modules, ideal for commercial backlit signs, channel letters and custom light box fabrication. Reference the table below for engineer-recommended LED spacing (DX/DY), installation density per square meter, and projected surface illuminance across standard light box thicknesses. This reference helps signage fabricators and project engineers deliver uniform, shadow-free brightness across every sign face, while optimizing module quantities and keeping project costs on budget.
| Light Box Thickness(mm) | LED Spacing(mm) | Installation density(PCS/m²) | Surface illumination(Lux) | Surface illumination(Lux) |
| 30 | DX=90, DY=65 | 170 | 8000~12000 | 170 |
| 50 | DX=100, DY=85 | 117 | 5000~6000 | 117 |
| 60 | DX=120, DY=100 | 84 | 3500~5000 | 84 |
| 80 | DX=140, DY=120 | 59 | 2500~3500 | 59 |
| 100 | DX=140 DY=140 | 51 | 2200~3000 | 51 |
| 120 | DX=140, DY=160 | 44 | 1800~2300 | 44 |
YS-MB5321 LED Sign Module Wiring Diagram & Installation Guide
Recommended Applications for YS-MB5321 LED Sign Module
1. 5–15cm Illuminated Channel Letters
The MB5321 is particularly suited to 5–15cm deep illuminated channel letters, where a two-LED module can provide a stronger lighting point without requiring an oversized housing. Installers can position the modules according to the width, curves and internal structure of each character.
2. Single-Sided Advertising Light Boxes
The module can be used in single-sided illuminated light boxes for retail advertising, storefront graphics and promotional displays. The 175° optical distribution allows the light to spread over a relatively broad area, helping produce a more consistent illuminated surface.
3. Airport, Subway and Transportation Signs
The IP67-rated construction makes the module suitable for properly designed illuminated signs in airports, subway stations and other transportation environments where dust and moisture protection can be important.
4. Custom-Shaped Signs and Logos
