Device for forming a light source

摘要

A device that creates non-visible visible-spectrum light comprises of a light source and optics elements that result in irradiated visible spectrum light rays with an intensity that is below a threshold for being visible by a normal observer. For a human observer using photopic or mesopic vision, light rays with an intensity below 3 cd/m2 and 0.003 cd/m2 respectively are not visible. Changes in vision regime used or ambient light, and the addition of irradiated visible light, result in additional visual effects. User and programmable controls can mediate the light source and optics to control the wavelengths and intensities of the light.

a light source, and irradiated light rays, where the light source creates light rays, and the irradiated light rays are in the visible spectrum and at an intensity that is below one of the thresholds for being visible to an observer.
