Abstract
A light-emitting carpet or light-emitting trim panel that employs a translucent polymer sheet that has a protective layer and a plurality of cavities configured to accept a plurality of light emitting diodes (LEDs) arranged to generate light where the LEDs are configured to align and project into the polymeric sheet cavities.
Claims19
A light-emitting carpet comprising:
- a first carpet layer that is configured to be exposed and come in contact with a vehicle occupant;
- a translucent polymer sheet layer providing a protective layer including a protective layer inner surface and protective layer outer surface and a plurality of cavities configured to accept a plurality of light emitting diodes (LEDs) arranged to generate light;
- a plurality of LEDs configured to align and project into said cavities;
- and
- a carpet backing layer;
- wherein said cavities are formed from a plurality of upstanding portions and said LEDs have a thickness (tLED), the translucent polymer sheet has a protective layer thickness tpL and the height T of the upstanding portions is provided by the following relationship:
- T
