摘要： Techniques and devices are provided for sensing image data from a scene and activating primary light sources based on information sensed from the scene. Subsets of a plurality of primary light sources may be activated to emit sensing spectrum of light onto a scene. Combined image data may be sensed from the scene while the subsets of the plurality of primary light sources are activated. Reflectance information for the scene may be determined based on the combined image data and combined sensing spectra. Spectrum optimization criteria for the primary light sources may be determined based on the reference information and a desired output parameter provided by a user or determined by a controller. The plurality of primary light sources may be activated to emit a lighting spectrum based on the spectrum optimization criteria.

摘要： 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.

摘要： 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.
