Abstract:
The invention provides amongst others a light emitting tufted carpet with a primary backing layer permeable to light, an optional adhesive layer, a waveguide comprising a light out-coupling site, and an optional secondary backing layer. The primary backing layer is provided with tufts. The waveguide is arranged to couple light source light of a light source in as waveguide light, and arranged to couple waveguide light out at the waveguide light out-coupling site to provide carpet light. The waveguide light out-coupling site is below the primary backing layer.
