DONCHAMP® Lucent - LumiBloc

Integrated LED Solutions

DONCHAMP® Lucent (LumiBloc) is an innovative specialty development from the DONCHAMP Acrylic Group, specifically designed for signage applications. DONCHAMP® Lucent (LumiBloc) acrylic has a unique optical performance with a light transmittance level of zero percentage (0%) when back illuminated. When unilluminated, the DONCHAMP® Lucent (LumiBloc) acrylic appears as a bright, gloss white acrylic, where with illumination, the product remains as gloss white acrylic, exhibiting 0% illumination / light transmission.


In a fabricated signage letter application as the letter returns, the DONCHAMP® Lucent (LumiBloc) White 4603 reflects the LED illumination from the edges, then creating a higher concentration of illumination through the front of the letter.
DONCHAMP® Lucent (LumiBloc) remains the same in being a gloss solid colour, exhibiting zero percent light transmission, during illumination.
DONCHAMP® Lucent (LumiBloc) enhances the letters surface illumination & the attention to the message of the illuminated sign.
