Zusammenfassung: | The present invention provides in one aspect a light device having a light guide. The light guide (20) has at least one major side defining a light extraction side (26). The light device further has at least one fibrous layer(30), typically a non-woven or woven fibrous layer, disposed on the major side of said light guide defining said light extraction side. At the light extraction side, the light device has a plurality of discrete bonding areas (40) at which the at least one fibrous layer is bonded to the major side of said light guide. In a particular aspect, the bonding areas define light extraction elements on the light extraction side. Such an arrangement typically provides for an easy, reliable and cost-effective light device useful for a variety of applications including, for example, illuminating the interior of a vehicle |
