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.

Abstract: A method and apparatus for a horticultural light for use in a horticultural facility that projects a substantially uniform target illuminance onto a flat surface or that projects increasing target illuminance onto a flat surface that increases as the beam angle increases with respect to the optical axis. A lens array of the horticultural light mechanically maintains an optimal separation distance between each LED of the horticultural light and the corresponding lens of the lens array. Each lens of the lens array receives the raw light distribution from the LED and then distributes an optically varied distribution having a nominal centerbeam intensity with an increasing beam intensity as the beam width increases. As the distance to target increases, so does the intensity of the light distribution, which projects a substantially uniform target illuminance, or an increasing target illuminance with increasing angle of incidence, onto a flat surface.
