    摘要: At the time of initial setting, a light amount adjusting unit (52) stores the brightness of illumination light as a first brightness for a projection video to have a desired brightness, and stores the light intensity of each color component of the illumination light as a first light intensity. A gain adjusting unit (61) sets the projection video to have a desired color and sets a gain value of at least one of the individual color components to be a maximum value, and stores the set gain value as a first gain value. At a second time point after the first time point, the light amount adjusting unit (52) adjusts the amount of the illumination light so that the brightness of the illumination light emitted from a light source unit (2) coincides with the first brightness, and calculates a ratio between a second light intensity and the first light intensity, the second light intensity being a light intensity of each of the color components of the illumination light emitted from the light source unit (2). The gain adjusting unit (61) corrects the gain values based on the ratio between the second light intensity and the first light intensity, and if the corrected gain values exceed the maximum value, reduces the gain values of the individual color components at the same ratio so that the largest gain value among the gain values of the individual color components becomes the maximum value. The light amount adjusting unit (52) increases the amount of the illumination light.

    摘要: Methods and systems for disinfecting a surface, can include a light source, and a transparent window located above the light source. The light source can be integrated into an object, and an outer surface of the object can be located above the transparent window. Light from the light source can irradiate the outer surface through the transparent window and from within the object to disinfect the outer surface of the object. The light can comprise violet and ultraviolet (UV) light. A photocatalytic layer comprising a photocatalytic material may also be located above the transparent window and below the outer surface.

    摘要: The present techniques concern methods and systems for controlling horticultural light sources illuminating a plant or crop during a distribution process including one or more phases, and more specifically relate to methods and systems for controlling horticultural lighting sources during an initial phase, a transit phase and a selling phase of the distribution process, each phase taking place a different location one from another. In some implementations, the present techniques allow illuminating the plant or crop according to a global dynamic lighting scenario, wherein at least a portion of the global dynamic lighting scenario is associated with a corresponding phase of the distribution process.
