Phlox uses innovative optical processes: a PMMA pipe lighted by a linear source made up of LEDs (Light Emitting Diodes). Our manufacturing process (CO2 laser) enables us to combine refraction and diffusion which improves backlight luminance. Up to 90% of the light injected can be reemitted on the surface. Thanks to the use of mathematical models, Phlox emits light in a determinist and perfectly controlled manner. The luminance of these optical pipes can be up to twice as high as the ones using diffusion.
