Abstract
A nightlight provides therapeutic effects on the body and mind including promoting relaxation, sleep and wakefulness. The nightlight includes a light source, a central processor, one or more controls, and a power supply. The light source produces at least three illumination modes including a sleep readiness mode, a sleep help mode and a wake-up mode. The sleep readiness mode produces monochromatic light of various selectable colors at about 40 lumens which may undulate in luminosity. Meanwhile, the wake-up mode produces substantially full spectrum light at higher luminosity. The controls allow a person to control the various light modes including selecting colors, time periods for activation, and transitions between colors during the sleep help mode. Moreover, the nightlight may include biological sensors for measuring physiological activity of the body. The nightlight may be incorporated into a bedside alarm clock which includes numerous features found in a traditional alarm clock.
