Abstract
A method and apparatus for a horticultural light for use in a horticultural facility that projects either a substantially uniform target illuminance onto a flat surface or an increasing target illuminance onto a flat surface that increases as the beam angle increases with respect to the optical axis. The horticultural light uses a refractor to receive the raw light distribution from one or more LEDs and then distributes an optically varied distribution having a minimized intensity at centerbeam with an increasing beam intensity as the beam width increases.
