Lighting may be provided using light sources such as lighting systems with arrays of light-emitting diodes. A lighting system may be integrated into a seat, a door panel, a dashboard, or other interior portions of a system such as a vehicle. The interior portions of the vehicle may be illuminated using lighting systems to provide ambient light, to provide custom surface textures and other decorative patterns, to provide icons, text, and other information, and to provide custom gauges and other illuminated regions. Illuminated regions may overlap sensors such as capacitive touch sensors, force sensors, and other sensors. The light-emitting diodes in a lighting system may supply light that passes through openings in a cover layer. The layer may be formed from fabric, leather, or other materials. Lens structures may guide light through the openings.

A vehicular lighting system includes at least one light emitting diode chip mini-pixel that has (i) a multi-quantum well stack electrified by a p-type material, an n-type material, and a plurality of electrodes, (ii) a nano-pattern light extractor and (iii) a lateral light confinement distributed Bragg reflector mirror. The at least one light emitting diode chip mini-pixel emits light to illuminate an area exterior or interior of a vehicle equipped with the vehicular lighting system.
