Abstract: Horticultural lighting may be provided by radio-controlled luminaires with integrated sensors. A distance from a bottom of the luminaire to a plant canopy is determined via the ultrasonic sensor at a predetermined interval. Upon determining that the distance from the bottom of the luminaire to the plant canopy is not at a predetermined distance, the distance is adjusted to the predetermined distance. The light spectrum over time on the plant is adjusted by varying a wavelength of the luminaire over a predetermined time period based on wireless instructions received from a master controller.

Abstract: The user of plasma light technology and remote lighting control techniques may enable a single master controller to control a large number of lighting fixtures. Multiple lighting fixtures may be equipped with control applications. Each control application may control the radio frequency driver of a lighting fixture that drives the plasma bulbs of the lighting fixture to produce light output for growing plants. The master controlled may execute on one or more computing devices. The master controller may send input instructions to the control applications of the lighting fixtures via a network. The instructions may be implemented by the control applications to command the radio frequency drivers to regulate a spectral distribution and/or intensity of the light output of the lighting fixtures.

Abstract: More efficient full spectrum lighting technology provides new lighting possibilities. A system that implements full spectrum lighting technology includes a lighting fixture that includes one or more light sources, in which the lighting fixture spectrally varies a light output of the one or more light sources in response to an electronic output signal. The system further includes a light sensor that monitors an output light spectrum provided by the one or more light sources. The system also includes an application controller that determines whether the output light spectrum from the one or more light sources follows a program. The application controller generates an electronic output signal to spectrally vary the light output of the one or more light sources in order to follow the program.
