Abstract

A lighting assembly for a vehicle includes a polymeric layer and a first conductive layer coupled to the polymeric layer. A first metallic foil defined a plurality of first foil apertures. A semiconductor layer includes a plurality of perovskites. A second conductive layer is coupled to the semiconductor layer. A second metallic foil defines a plurality of second foil apertures. The lighting assembly includes transparent overmold, extending through the plurality of first foil apertures, the first and second conductive layers, the semiconductor layer, and the plurality of second foil apertures to contact the polymeric layer.

First claim

What is claimed is:

1. A lighting assembly for a vehicle, comprising:
a polymeric layer;
a first conductive layer coupled to the polymeric layer;
a first metallic foil defining a plurality of first foil apertures;
a semiconductor layer including a plurality of perovskites;
a second conductive layer coupled to the semiconductor layer;
a second metallic foil defining a plurality of second foil apertures; and
a transparent overmold extending through the plurality of first foil apertures, the first and second conductive layers, the semiconductor layer, and the plurality of second foil apertures to contact the polymeric layer at uniform intervals.

2. The lighting assembly of claim 1 , wherein the second conductive layer comprises a transparent conductive oxide.

3. The lighting assembly of claim 1 , wherein the semiconductor layer is configured to emit light in response to an electrical potential being generated between the first and second conductive layers.

4. The lighting assembly of claim 1 , wherein the polymeric layer comprises poly ether ether ketone.

5. The lighting assembly of claim 1 , wherein the first and second metallic foils comprise copper.

6. The lighting assembly of claim 1 , wherein the transparent overmold comprises acrylic.

7. The lighting assembly of claim 1 , wherein the transparent overmold contacts opposing edges of the polymeric layer.

8. The lighting assembly of claim 1 , wherein the polymeric layer is configured to be installed on an exterior of a vehicle.

9. The lighting assembly of claim 1 , further including:
a dielectric layer positioned adjacent to the semiconductor layer.

10. The lighting assembly of claim 1 , wherein the second metallic foil comprises opposing second foil edge portions spaced apart and positioned proximate opposing edges of the polymeric layer.

11. A vehicle lighting system, comprising:
a vehicle control module configured to operate a vehicle in an autonomous driving state;
a controller configured to activate a light source in response to the autonomous driving state; and
a lighting assembly forming a strip, wherein an electrical connection contacts the strip in a single location, and wherein the lighting assembly comprises:
a polymeric layer;
a semiconductor layer configured to emit light, wherein the semiconductor layer is positioned between first and second conductive layers;
a metallic foil defining a plurality of foil apertures; and
an overmold extending through the plurality of foil apertures, the semiconductor layer, and the first and second conductive layers to contact the polymeric layer.

12. The vehicle lighting system of claim 11 , wherein the semiconductor layer includes a plurality of printed perovskites configured to emit light.

13. The vehicle lighting system of claim 11 , wherein the overmold extends through the plurality of foil apertures.

14. The vehicle lighting system of claim 11 , wherein the vehicle control module is operably coupled to the controller and configured to send a signal to the controller signaling the vehicle is operating in the autonomous driving state.

15. The vehicle lighting system of claim 11 , wherein the plurality of foil apertures are linearly arranged in a center portion of the metallic foil.
