  • Patent number: 10309613
    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.

  • Patent number: 10303920
    Abstract: Introduced here are computer programs and associated computer-implemented techniques for determining reflectance of an image on a per-pixel basis. More specifically, a characterization module can initially acquire a first data set generated by a multi-channel light source and a second data set generated by a multi-channel image sensor. The first data set may specify the illuminance of each color channel of the multi-channel light source (which is configured to produce a flash), while the second data set may specify the response of each sensor channel of the multi-channel image sensor (which is configured to capture an image in conjunction with the flash). Thus, the characterization module may determine reflectance based on illuminance and sensor response. The characterization module may also be configured to determine illuminance based on reflectance and sensor response, or determine sensor response based on illuminance and reflectance.
