A light-emitting device assembly includes a concave optical collector with a cavity, an emitter array of light-emitting elements, a transparent substrate across an open end of the collector, a structured lens, and an angular filter. The emitter array is positioned within the package cavity and emits from its emission surface output light that exits the cavity from the open its end through the substrate, and enables selective activation of and emission from individual elements of the array. The structured lens is formed on or in the substrate, and comprises micro- or nano-structured elements resulting in an effective focal length less than an effective distance between the structured lens and the emission surface. The angular filter is positioned on or in the substrate or on the emission surface and exhibits decreasing transmission or a cutoff angle with increasing angle of incidence.

A method and apparatus for a light fixture that uses current sharing across any one or more parallel LED strings within the light fixture. A processor determines the current requirements of the one or more LED strings that are needed to produce a given intensity level. The processor then apportions the current generation capability of a power supply across all active LED strings using time division multiple access (TDMA) whereby each LED string conducts its apportioned current within its allocated time slot to the mutual exclusion of the remaining active LED strings in any given time period. The light fixture utilizes LEDs with increased forward voltage interspersed with LEDs having reduced forward voltage in the same LED string. A processor utilizes shunt devices across the one or more LEDs with increased forward voltage to substantially match the cumulative forward voltage of each LED string.
