Abstract
A light source carpet includes a light source and a tufted carpet. The tufted carpet includes a primary backing layer having top and bottom faces. The primary backing layer further includes yarns integrated in the primary backing layer with tufts protruding from the primary backing layer at the top face, where the tufts form a carpet top face. The light source is configured to illuminate the primary backing layer. The intensity of the light at the carpet top face is smaller than the intensity of the light at the top face. The light source is further configured to generate light having a wavelength in the range of 200-400 nm.
