One current example of lit transparent roof can be found on BMW i7.
I took time during Shanghai autoshow to visit Saint-Gobain Sekurit (French company) to exchange about lit roof. This is a topic we have never covered in DVN lighting nor DVN interior.
The glass is used as a light-diffusing surface, reproducing the desired pattern design. LEDs are placed along the edges to inject light into the glass through an optical system laminated within it.
Similar technology was also shown on Antolin Booth
