摘要： Optical system for facilitating plant growth is provided. The optical system can produce a light beam having a full width at half-maximum (FWHM) angle of greater than 120 degrees in one or more transverse directions, wherein the transverse direction is perpendicular to the optical axis of the light beam.

摘要： An optical system for facilitating plant growth can include one or more light sources operable to produce a light density distribution having a central portion and a peripheral portion. The light density distribution having a central portion has a lower light density than the peripheral portion, thereby producing a substantially non-uniform light density distribution.
