    Abstract: Melanopic dose rate and dose are calculated in a virtual environment. A computer generated model of an actual or planned building is used as the virtual environment. Indirect and direct spherical irradiances are calculated using convex polyhedra throughout the virtual environment, and each is multiplied by a melanopic conversion factor. The two are added, then adjusted for a human's angular responsivity and age. Building design features or lighting devices may be adjusted to provide a required melanopic dose rate. A camera is used to capture a panoramic image, which is calibrated to tristimulus values, and used with the spectral power distribution of the light sources to derive the melanopic dose rate.

    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: Spectral irradiance distributions are calculated within a virtual environment based on arbitrary light source spectral power distributions. Architectural, horticultural and aquacultural lighting control systems use the calculated results to control both the intensity and spectral power distribution of the electric light sources. Energy consumption may be minimized while maintaining optimal occupant visual comfort and plant health.

    Abstract: Given the complexity of architectural spaces and the need to calculate spherical irradiances, it is difficult to determine how much ultraviolet radiation is necessary to adequately kill airborne pathogens. An interior environment with luminaires is modeled. Spherical irradiance meters are positioned in the model and the direct and indirect spherical irradiance is calculated for each sensor. From this, an irradiance field is interpolated for a volume of interest, and using known fluence response values for killing pathogens, a reduction in the pathogens is predicted. Based on the predicted reduction, spaces are built accordingly, and ultraviolet luminaires are installed and controlled.

    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.
