| titleOfInvention | Apparatus, method and system for providing tunable circadian illumination with constant perceived brightness and color |
| abstract | Newly discovered retinal ganglion cell photoreceptor melanopsin, which is not present in the fovea of the eye but is distributed in the remaining retinal body of a human, provides non-visual biological/physiological inputs that induce circadian rhythm entrainment, as well as visual inputs that affect perceived brightness; this perceived brightness is not the brightness of the object, which is usually associated with the illumination and perceived color of the object in the central view, but rather the brightness perception of the entire space or task background. Improvements to circadian lighting systems based on melanopsin stimulation are discussed whereby ambient and/or device background lighting can be tuned temporally over a predetermined color temperature range from a first lighting subset with a higher melanopsin content to a second lighting subset with a lower melanopsin content, or vice versa, according to a desired circadian cycle, and in such a way that the net light output is of constant perceived brightness and color throughout the time tuning. |
