Sandwich Luminous Signs
Sandwich Luminous Letter & Signs feature a layered construction that delivers perfectly uniform illumination. The sandwich design combines a rigid aluminum composite back panel, a precision LED matrix, and a high-diffusion front panel.
This construction method produces the most even light distribution available, with no hot spots or dark areas. The ultra-slim profile (just 35mm) makes these signs ideal for modern architectural environments.
