Efficient and uniformly distributed illumination from multiple source luminaires
Abstract:
Light projecting devices for integrating the light output from multiple light emitting quasi point sources into unified predetermined light patterns. The multiple light emitting quasi point sources (such as LEDs [Light Emitting Diodes]) are generally stacked with a common optical axis, each of the light emitting quasi point light sources further surrounded by a ring collimator designed to collect and project a radial beam of light away from the optical axis. In some embodiments, a series of individual collimators surround each of the light emitting quasi point sources and substitutions for the ring collimator forming an array of beams projected away from the optical axis. Further, either of the systems, whether incorporating a ring collimator or a series of individual collimators, may use reflecting surfaces to intercept and redirect the radiating collimated light into distribution patterns ranging from focused beams to ambient broad light distribution.
