One current example of lit transparent roof can be found on BMW i7. DVN took time during Auto Shanghai ’25 to visit French supplier Saint-Gobain Sekurit to learn more.
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.
For example, Weidplas has integrated ambient lighting in different panoramic roofs. With a special technology the company is able to laser invisible microstructures into the volume of transparent materials, which are hidden until lit.
When autonomous driving vehicles become rolling offices and living rooms then it makes sense that the panoramic roofs become more and more areas for natural, ambient and functional lighting.
