A light source useful for architectural lighting, general lighting, street lighting, or other lighting applications includes a plurality of light emitting diodes. A least some light emitting diodes can be sized between 30 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. A controller may be connected to selectively power groups of the plurality of light emitting diodes to provide different light beam patterns.

Flexible low Z-height LED arrays with controllable light beams

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.

Rayleigh spacing limited and low z-height LED arrays

A light source includes a plurality of light emitting diodes, with at least some light emitting diodes sized between 30 microns and 500 microns. A plurality of micro-optics are associated with a light guide plate and sized less than 1 millimeter, with each micro-optic positioned over at least one of the plurality of light emitting diodes. At least some of the combinations of light emitting diode and micro-optics associated with the light guide plate are positioned within a distance to each other sufficient to provide a substantially uniform light beam.
