1. A light source comprising:
a plurality of light emitting diodes each having a light emitting surface sized between 30 microns and 500 microns; and
a plurality of micro-optics each having an optical axis and dimensions perpendicular to the optical axis of less than or equal to 1 millimeter, each micro-optic spaced apart from adjacent ones of the micro-optics by at least 1 millimeter, each micro-optic positioned over at least one of the plurality of light emitting diodes to collect and direct light emitted through its light emitting surface, at least some of the micro-optics oriented with their optical axes at an angle other than 90 degrees with respect to the light emitting surfaces of the light emitting diodes over which they are positioned.
