    Abstract: Electric light sources typically exhibit temporal variations in luminous flux output, commonly referred to as “flicker.” Flicker, or temporal modulation, is known to influence the growth, health and behavior patterns of humans, and is also linked to growth, health and behavior patterns throughout the growth cycle of plants and animals. Control of peak radiant flux emitted by a light source to temporally modulate a light source will allow for the control of plants and animals for sustainable farming including but not limited to horticultural, agricultural, or aquacultural endeavors. The light source allows the transmission of daylight, which is combined with the flicker.

    Abstract: Laser light emanates from optical components that are mounted on a substrate, each optical component being coupled to an optical fiber that delivers laser radiation combined from multiple lasers. A linear or elliptical holographic diffuser is located to diffuse the light emanating from the optical components. The laser wavelengths excite plant photopigments for predetermined physiological responses, and the light source intensities may be temporally modulated to maximize photosynthesis and control photomorphogenesis responses. Each laser is independently controlled. At least one laser emits ultraviolet-C radiation.

    Abstract: A biological lighting system to provide temporally- and spatially-modulated photon flux output and spectral power distributions to plants on a circadian and circannual basis, or circadian and life cycle basis, to maximize effective and efficient growth in a horticultural setting. The photon flux or irradiance output and the spectral power distribution are modulated to match circadian and circannual rhythms, with individual or multiple luminaires controlled through one or more controllers. Different lighting spectra can be employed depending on the direction of illumination. The photon flux or irradiance output and the spectral power distribution may be set as best suited for any particular plant species, and the system is also useful for raising animals.

    Abstract: Monthly average DLI values for a specified geographic location, or a greenhouse, polytunnel or other controlled environment at the specified geographic location, are calculated from historic reference data from weather stations. The calculations are a prediction based on the geographic similarity of the specified location to the locations of the weather stations. Calculations may also be based on the proximity of the weather stations. Weather data from satellites may also be used. A calculation indicates whether a proposed controlled environment in a specified geographic location will provide sufficient monthly DLI for a given crop with known DLI requirements. Where the DLI is insufficient, an amount of supplemental electric lighting is specified.

    Abstract: In an example, an expected sky condition is calculated for a geographic location, a time of day, and a date based on a mathematical model. A predicted distribution of direct and interreflected solar radiation within the environment is calculated based on the expected sky condition. Measurement data from one or more photosensors is obtained that provides measurements of an initial distribution of direct and interreflected radiation within the environment, including radiation from solar and electrical lighting sources. A target distribution of direct and interreflected artificial electromagnetic radiation produced by electrical lighting is determined, based on the measurement data and the predicted distribution of direct and interreflected solar radiation, to achieve the target distribution of direct and interreflected radiation within the environment. Output parameters are set to one or more devices to modify the initial distribution to achieve the target distribution of direct and interreflected radiation within the environment.
