Abstract
A light source useful for architectural lighting, general lighting, street lighting, or other lighting applications includes a plurality of light emitting diodes, with at least some light emitting diodes sized between 50 microns and 500 microns. A plurality of micro-optics sized less than 1 millimeter are positioned over at least some of the plurality of light emitting diodes. Each combination of light emitting diode and associated micro-optic is positioned within a Rayleigh distance to each other, sufficient to both present a substantially uniform visual appearance and provide a substantially uniform light beam. In some embodiments the height of the light emitting diodes, their supporting substrate and electrical traces, and associated optics is less than 5 millimeters.
