Abstract An inventive light source includes a substrate and a set of multiple light-emitting elements. The substrate is transparent or reflective for visible light. The light-emitting elements are positioned on or within the substrate. Each light-emitting element comprises one or more inorganic microLEDs that are arranged to generate and emit visible output light to propagate out-of-plane relative to a corresponding localized area of the substrate around that light-emitting element. Each light-emitting element of the set being sufficiently small in at least one transverse dimension, and the light-emitting elements occupying a sufficiently small fraction of an areal extent of the set, so as to enable visual observation of a scene through or reflected by the substrate along a sight line that passes through the set of light-emitting elements.
