| Research Abstract |
Non-image-forming vision induces physiological responses such as circadian photoentrainment and pupillary light reflex. It is indicated that its sensitivity is high to optical radiation of short wavelength and that the spectral sensitivity curve is bimodal due to phototransduction of intrinsically photosensitive retinal ganglion cells and input from cones. Next-generation luminous environment design is defined as that considering both image-forming and non-image-forming visual properties, and based on spectral distribution. Such luminous environment design requires integration of daylighting including indirect utilization of sunlight, hybrid lighting systems, and temporal and spatial lighting controls.
