Diffuser Synergy21 S21-LED-PR20045 Transparent PMMA, for LED, Depth 2000 mm, 100 g

Synergy21 S21-LED-PR20045 is a transparent PMMA (polymethyl methacrylate) diffuser designed for use with LED strips in an aluminium U-profile mounting channel. The combination of an aluminium body and a clear acrylic cover provides structural support, mechanical protection and efficient light transmission with minimal diffusion. With a depth of 2000 mm and a single-piece supply, this diffuser suits linear installations where a transparent cover is required to preserve brightness and colour rendering while protecting LED modules from dust and contact.

Advantages

The aluminium profile offers mechanical strength and assists heat dissipation from LED strips, contributing to longer service life of the light source. The clear PMMA diffuser ensures high light transmission and maintains colour fidelity while shielding LEDs from dust and physical impact. The U-shaped cross-section secures LED strips and eases alignment during installation. Compatibility with both surface and recessed mounting increases flexibility for a range of interior and fixture types.

Suitable for

• Architectural accent lighting and coves
• Under-cabinet and furniture illumination
• Retail displays and shelving lighting
• Showcases, exhibition stands and signage

Key specifications

• Body material: aluminium for structural support and heat dissipation
• Diffuser material: clear PMMA (acrylic) for high light transmission
• Profile shape: U-profile designed to house LED strips securely
• Mounting options: suitable for surface mounting and recessed installation
• Protection: diffuser shields LED strips from dust and physical contact
• Light effect: transparent cover provides minimal diffusion and preserves brightness and colour fidelity

How to use

Measure and cut the aluminium profile to the required length and prepare the installation surface. Insert the LED strip into the U-profile channel, ensuring the adhesive backing is compatible with the aluminium or use mounting clips for additional fixation. Snap or slide the clear PMMA diffuser into place to cover the LED strip. For recessed mounting, create the necessary slot or groove and secure the profile in the recess; for surface mounting, fix the profile using screws or appropriate mounting brackets. Connect the LED strip to a compatible power supply following electrical safety guidelines.

Usage recommendations

To optimise thermal performance and extend LED lifetime, ensure good contact between the LED strip and the aluminium profile for effective heat transfer. Clean the diffuser regularly with a soft, non-abrasive cloth and mild detergent to maintain light transmission. Avoid solvents that can damage PMMA and avoid exposing the profile to direct high-impact loads. Verify that the LED strip width fits the profile channel before final installation.
