A transparent roof assembly for a vehicle roof comprises a panel with a transparent area, a light source arranged to provide light into the panel and an out-coupling pattern arranged on the surface of the transparent area of the panel. The out-coupling pattern comprises dots of a light-redirecting material for out-coupling of light introduced into the panel and propagating in the panel, wherein the dots each have a representative diameter of 150 microns or less, preferably 80 microns or less and wherein a total dot surface area of the dots of the out-coupling pattern is smaller than 10% of a total surface area of the transparent area. Thus, the transparent area appears transparent during daytime looking from an interior of the vehicle to an exterior of the vehicle, while sufficient light is provided into the interior when the light source is switched on.

A vehicle interior light intensity mapping system comprises at least one light detector configured to identify an intensity of light distributed in a plurality of regions in the vehicle. The light detector comprises an optic device comprising at least one aperture configured to receive light from a plurality of directions distributed in a passenger compartment of a vehicle. The light detector further comprises at least one sensor configured to receive the light from the plurality of directions. A controller is configured to identify an intensity of the light in each of a plurality of regions of the vehicle, wherein each of the regions corresponds to a different direction of the light received through each of the plurality of apertures of the optic device.

A driver may be used to drive an electrically controllable optically active material in a privacy structure. In some examples, the driver receives power from a power source at a supply voltage and a supply apparent power level and converts the power received from the power source down to a converted voltage and a converted apparent power level. The converted voltage is less than the supply voltage and the converted apparent power level is less than the supply apparent power level. The driver may deliver power at the converted voltage and the converted apparent power level to a voltage convertor, which increase the converted voltage to an operating voltage. The driver can further condition power received from the voltage convertor having the operating voltage and operating apparent power level to provide a drive signal and provide the drive signal the electrically controllable optically active material of the privacy structure.

This disclosure relates generally to glass products having a UV protective coating. The coating is a porous, nano-structured coating having pores sized within the range of UV radiation. The porous structure may scatter UV light, protecting laminated interlayers and interior space protected by the glass products. The UV protective coating may be used in glass laminates having UV-sensitive interlayers, including switchable films where UV exposure may be limited.

A privacy glazing structure may include an electrically controllable optically active material that provides controlled transition between a privacy or scattering state and a visible or transmittance state. To make electrical connections with electrode layers that control the optically active material, the privacy glazing structure may include electrode engagement regions. In some examples, the electrode engagement regions are formed as notches in peripheral edges of opposed panes bounding the optically active material. The notches may or may not overlap to provide a through conduit in the region of overlap for wiring. In either case, the notches may allow the remainder of the structure to have a flush edge surface for ease of downstream processing.
