Abstract
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.
