LED Modules for PMMA
You have selected your acrylic sheet, and now comes the question: how to illuminate it so the finished product looks clean and professional, rather than like a spotted blanket of uneven hotspots? LED modules engineered for acrylic (PMMA) are specifically optimized to work in harmony with cast and extruded acrylic diffusers. Featuring ultra-wide beam optics, they create a beautifully smooth, seamless surface even in slim lightboxes and low-depth channel letters. If you are fine-tuning your signage lighting setup, these dedicated modules ensure your brand shines exactly as intended.

FAQ – Frequently Asked Questions
Why do I need special modules for PMMA (plexiglass)?
Standard LEDs can create sharp points of light (known as hotspots) on plexiglass, which doesn't look good. Modules for PMMA feature specially shaped lenses with a wide beam angle that diffuses the light just a short distance from the source. As a result, the final backlighting is perfectly smooth and uniform, even behind opal or colored sheets.
How deep does the box need to be so individual diodes aren't visible?
Thanks to the modern optics of these modules, you can go surprisingly low with the box depth—often 5 to 8 cm is enough. Generally, however, the closer the LED is to the plexiglass, the denser the module grid should be. If you are unsure about the layout, feel free to send us your dimensions, and we will map it out for you right here in Zlín.
Will the plexiglass yellow or crack from the heat of the LED modules?
Not at all. Unlike old fluorescent tubes, LED modules produce minimal heat. Moreover, our plexiglass sheets are UV-stable and heat-resistant, making the combination of LEDs and PMMA completely safe even for continuous 24/7 operation. Your sign will remain beautifully clear or brightly colored for years to come.
What about installation—can I stick them on myself?
Working with them is basically like a puzzle. Each module has strong adhesive tape on the back, allowing you to lay them out and tack them into place inside the box first. For final outdoor installation, we recommend adding a drop of adhesive or a small screw so the modules stay firmly anchored despite large temperature swings in summer and winter.
