A new patent application from Tesla US20190106055A1 suggests an advanced sunroof lighting system that allows you to manipulate the incoming light according to requirement. A tint layer is sandwiched between two transparent layers and is electrically controllable to allow none, some, or all of the sunlight incident to the sunroof. A ‘transparent lighting layer’ is added between the tint layer and the second transparent and has LEDs embedded in it. This layer also contains multiple scattering centers which redirects light from the side of the layer to the vehicle cabin. The transparent lighting layer is configured to provide uniform distribution of light in the car.
