Abstract

A computer-implemented method is disclosed for controlling one or more luminaires that are configured to illuminate one or more plants with artificial light. The artificial light comprises a plurality of artificial light components. Each of the artificial light components is of a respective wavelength or wavelength range. The plurality of artificial light components comprises a first artificial light component of a first wavelength or wavelength range and a second artificial light component of a second wavelength or wavelength range. Further, sunlight is incident on the one or more plants. The sunlight comprises a plurality of sunlight components. Each of the sunlight components is of a respective wavelength or wavelength range. The plurality of sunlight components comprising a first sunlight component of the first wavelength or wavelength range and a second sunlight component of the second wavelength or wavelength range. The method comprises receiving a signal indicative of a non-spectrally resolved irradiance value of sunlight that is incident on the one or more plants.

A computer-implemented method for controlling one or more luminaires that are configured to illuminate one or more plants with artificial light, the artificial light comprising a plurality of artificial light components, each of the artificial light components being of a respective wavelength or wavelength range, the plurality of artificial light components comprising a first artificial light component of a first wavelength or wavelength range and a second artificial light component of a second wavelength or wavelength range, the method comprising:

receiving a signal indicative of a non-spectrally resolved irradiance value of sunlight that is incident on the one or more plants,
determining, based on the non-spectrally resolved irradiance value, an irradiance value for the first artificial light component and an irradiance value for the second artificial light component,
storing sunlight reference data indicating, for each of a plurality of reference non-spectrally resolved irradiance values, a reference irradiance value for a first sunlight component and a reference irradiance value for a second sunlight component,
determining the irradiance value of the first artificial light component and determining the irradiance value of the second artificial light component based on the sunlight reference data, and
controlling the one or more luminaires such that they provide artificial light to the one or more plants having the determined irradiance value for the first artificial light component and the determined irradiance value for the second artificial light component, such that the one or more plants receive light of the first wavelength or wavelength range at a predefined irradiance value for the first wavelength or wavelength range and light of the second wavelength or wavelength range at a predefined irradiance value for the second wavelength or wavelength range.
