A nightlight is provided for providing therapeutic effects on the human body
and
mind including promoting relaxation, sleep and wakefulness. The nightlight includes
a housing, a light source, a central processor, one or more controls, and a power
supply. The light source produces at least three modes having various light properties.
The light modes include a sleep readiness mode, a sleep help mode and a wake-up
mode. The sleep readiness mode produces light at about 40 lumens and preferably
includes only light from the blue and yellow portions of the visible light spectrum.
The sleep help mode produces monochromatic light in the blue or green spectrum.
Preferably, the light undulates at a frequency of one cycle per second to one cycle
per minute at a luminosity of between 5 lumens and 25 lumens. Meanwhile, the wake-up
mode produces substantially full spectrum light at approximately 1,600 lumens.
The processor and controls allow a person to select and control the various light
modes. Moreover, the nightlight may include biological sensors for measuring physiological
activity of the body.
