Abstract:
The invention provides a light emitting tufted carpet (1). The carpet (1) comprises a primary backing layer (100), an optional secondary backing layer (200), an optional adhesive layer (300), a plurality of carpet integrated LEDs (40) arranged to generate carpet light (41), and a first electric conductor (10) and a second electric conductor (20). The first electric conductor (10) and the second electric conductor (20) are arranged to provide power from a power source (50) to the LEDs (40). The primary backing layer (100) comprises a first felt layer (30′), or the optional secondary backing layer (200) comprises second felt layer (30″), or both the primary backing layer (100) and the optional secondary backing layer (200) comprise felt layers (30′,30″). One or more of the first electric conductor (10) and the second electric conductor (20) are at least partially integrated in one or more of the first felt layer (30′) and the second felt layer (30″).
