BackMatrix-49-2080 Nichia LED Module tunnable white CRI80 2700-6500K 2400lm 98 LEDs 24V 10.1W 180° 28x28cm (16000 lm/sqm)

The BackMatrix-49-2080 Tunable White is a large-area two-channel LED module for luminous ceilings, walls and backlit elements where both colour temperature and surface uniformity must be adjustable. It combines 2700 K and 6500 K Nichia channels on one 280 × 280 mm board and covers a tunable range from warm white to daylight white.

The module uses Nichia chip-scale LEDs with an exceptionally wide 180° distribution. This helps create homogeneous luminous surfaces at shallow installation depths and makes tunable-white backlighting practical even where ceiling void or light-box depth is limited.

Designed for uniform large-area backlighting

BackMatrix modules are designed for backlighting behind diffusers rather than narrow-beam illumination. The LEDs are distributed across a square rigid PCB so the light can blend over a short optical distance into a broad, visually uniform luminous surface.

The 180° emission is especially valuable in stretched ceilings and shallow light boxes because the light spreads laterally across the diffuser instead of concentrating directly above each LED.

The wide distribution can support luminous elements with installation depths around 30 mm when the diffuser, module spacing and reflectance are designed appropriately.

Billboards, signage and illuminated displays

The regular LED layout is well suited to billboard backlighting, signage, light boxes, exhibition displays and other illuminated graphics. Several modules can be arranged behind a translucent face to cover large areas while maintaining repeatable LED spacing.

The final cavity depth and module spacing should be selected according to the diffuser transmission, required brightness and acceptable hotspot visibility.

Tunable white and human-centric lighting

With a compatible two-channel controller, the installation can shift from warm 2700 K light to cool 6500 K light and intermediate tones. This allows the same luminous ceiling or wall to support relaxed evening scenes, neutral everyday lighting and cooler task-oriented scenes.

This makes the module useful in offices, education, healthcare, hospitality and residential interiors where time-of-day lighting or human-centric lighting is part of the design concept.

Two-channel 24 V integration

The warm and cool channels require independent control from a compatible tunable-white controller. The power supply and controller should be sized for the maximum simultaneous load required by the intended lighting scenes.

The insulation-displacement terminal allows solderless connection and simplifies installation when several modules are distributed behind one large diffuser.

High-quality Nichia LEDs

BackMatrix uses specified Nichia LEDs rather than unidentified generic components. This gives better control over luminous performance, colour consistency and long-term behaviour when many modules are used together in one illuminated surface.

The white-light variants are colour sorted for consistent appearance across multi-module installations. For more background on white-light quality, see our colour temperature guide.

Designed and manufactured in Germany

We develop and manufacture professional rigid LED modules in Germany, combining more than 20 years of LED application experience with controlled SMT production and application engineering. BackMatrix products are designed as repeatable large-area light engines for professional backlighting, signage and custom luminaires.

For OEM and project customers, we can also support LED selection, PCB adaptation, thermal design, optical layout, prototyping and series production. This is especially useful for large illuminated surfaces, where LED pitch, diffuser distance, luminous density and module spacing must work together as one optical system.
