Despite the advantages of
LED lighting the limited efficiency
of LED luminaires raises
questions regarding their
use in sustainable CEA
Furthermore, matching the colour spectrum and
intensity to the crop type,
growth phase and desired
crop characteristic is challenging due to the interactions
between plant, light source
As such, there is the need
to optimise the periods
over which LEDs are used and
also the spectrum of light
that they produce.
To address this, Cultinova collaborated with a producer of high performance LED luminaires and a UK University to realise a smart horticultural lighting system that measures light spectrum and intensity at crop level and controls luminaires to ensure exactly the right amount of light is applied to the crop at the right time. This system enables new opportunities for improving crop production while reducing the amount of energy used by horticultural lighting systems.
Control colours individually varying spectral intensity and composition
Vary spectral intensities across zones with or without light level feedback
Maintain constant PPFD levels indepenently of available sunlight
Apply dynamic control only when needed for energy saving and increased LED lifetimes
Since its development in 2017, Cultinova's dynamic lighting system was has been applied in various commercial and research CEA settings.
