BackMatrix-49-3090 Nichia LED Module pure white 4000K CRI90 2150lm 49 LEDs 24V 14.11W 29x29cm (27423 lm/sqm)

BackMatrix-49-3090 Nichia LED Module Neutral White 4000K CRI90, 3 Brightness Levels, 29 x 29 cm

The BackMatrix-49-3090 4000K is a high-output LED module for backlighting large surfaces: light boxes, billboards, signs and luminous ceilings. Its 49 Nichia LEDs on a 290 x 290 mm board deliver up to 3155 lm of neutral white 4000K light, about 38,000 lm per square meter, with an efficacy of up to 154 lm/W and a color rendering index above 90, so printed graphics, materials and colors look natural.

A unique feature is the on-board brightness setting: with two switches on the module, you can select one of three levels, 1090, 2150 or 3155 lm, at 7.06, 14.11 or 21.17 W. This lets you adapt the same module to the depth and the material of the light box, or balance the brightness of different areas, without an external dimmer. The module operates at 24 V constant voltage, needs no additional cooling, and is made in Germany with a 5-year warranty. The 4000K light color creates a clean, focused pure white light that supports concentration and alertness.

Applications of the BackMatrix-49-3090 LED Module 4000K

Designed for even backlighting of large surfaces, the BackMatrix-49-3090 is used in the following main applications:

• Billboards and luminous ceilings: For backlit billboards, large light boxes and luminous ceilings, BackMatrix-49-3090 modules are mounted side by side behind the translucent surface to light it evenly from edge to edge. See our LED modules for luminous ceilings.
• Signage: In illuminated signs, logos and display boxes, the modules provide bright, uniform backlighting with a low number of components. The three brightness levels make it easy to match different sign depths and materials. More about LED modules for signage backlighting.
• Backlighting behind translucent materials: Behind stretch ceilings, acrylic, onyx, marble, textiles or printed graphics, BackMatrix modules create evenly lit walls, ceilings, counters and 3D elements, as well as displays at trade fairs and exhibitions. Read our guide on how to create a light ceiling with LED modules.
• High-quality white light: With a color rendering index above 90, the module shows printed colors, materials and products naturally, ideal for premium advertising, retail and architectural surfaces. The 4000K color temperature gives a clean, focused pure white light that supports concentration and alertness.

Why BackMatrix for Large Illuminated Surfaces

• Fewer parts per square meter: each module covers 290 x 290 mm with an even grid of Nichia LEDs, so about 12 modules light one square meter, much faster to install than rows of LED strips or many small modules.
• Even light distribution: the regular LED grid blends into a uniform surface behind a diffuser, without visible hotspots, the basis for homogeneous light boxes, signs and luminous ceilings. Match the distance to the diffuser to the LED spacing and the beam angle, as described in our guide on LED pitch and distance to cover for optimum backlighting.
• Solder-free connection: an insulation displacement terminal accepts connection cables of up to 1 mm² (AWG 18), for example our cable SKU 37592, without soldering; we recommend the BackMatrix tool bit (SKU 95402). Holes on the board allow the cables to be fixed with cable ties.
• Simple 24 V system: modules are connected in parallel to one 24 V constant voltage power supply, so any number of modules can be combined to the size of the surface, limited only by the power supply and the cable cross-section.
• Consistent color: Nichia LEDs binned to a 3-step MacAdam ellipse keep brightness and light color uniform across all modules of a large surface.

Installation and Operation

• Mounting: fix the module flat on a stable surface, supporting the board at suitable mounting points; do not bend the board or clamp the components. No additional cooling is required.
• Connection: connect the modules with the solder-free insulation displacement terminal, using cables of up to 1 mm² (AWG 18), and fix the cables with cable ties through the holes on the board; soldering is possible as an alternative.
• Power supply: connect several modules in parallel to a stabilized 24 V DC constant voltage LED driver with short-circuit, overload and overtemperature protection, sized for the total load (up to 21.17 W per module at the full level) plus a safety margin. For large surfaces, feed the modules in groups with adequately sized cables to keep the voltage drop low.
• Handling: observe standard ESD precautions, keep the modules away from aggressive chemicals, and store and operate them at 10% to 60% relative humidity.
• Safety: installation must comply with all applicable electrical and safety standards and should be carried out by a qualified electrician.

Why the BackMatrix-49-3090 Outperforms Low-Cost LED Modules

Compared with low-cost LED modules, the BackMatrix-49-3090 differs in three areas that decide how long a lighting installation performs well:

• LED quality: we use only brand-name LEDs from Nichia, the Japanese LED market leader whose researchers invented the blue and white LED technology, with full manufacturer datasheets and performance tested in the lab and in real applications. Low-cost strips often use LED chips of unknown origin, without certified data, so their quality and color vary from one purchase to the next.
• PCB design and materials: high-quality materials and a design without mechanical and electrical weak points, for good current flow, heat transfer and long-term reliability.
• Realistic specifications: all values are measured at a junction temperature of 65°C, so the performance in our datasheet matches what you get in a real installation.
