In one embodiment, the present invention pertains to a night light assembly which plugs directly into an electrical wall receptacle to provide a beam of light that can be directed along different paths. The assembly comprises a housing having a plug with projecting blade contacts for insertion into a wall receptacle and a light sensor for automatically controlling the activation and de-activation of the lamp of the nightlight. A cover member rotatably supported by the housing includes a lens, a low wattage lamp, a support member, and a lamp retaining member. The low wattage lamp in the cover assembly is coupled, via sliding contacts, to the blade contacts in the base housing. This arrangement allows the cover and the lamp to be rotated as a unit relative to the base housing without limitation. The lamp retaining member is non-rotatably coupled to the cover and is rotatably engaged by a retaining member fixed to the housing member. The longitudinal axis of the low wattage lamp located in the lamp retaining member is aligned along the rotational axis of the lens in the cover to permit both direct and reflected light to pass through the lens in the cover without being obstructed by the base of the lamp. The disclosed assemblage is a new improved nightlight of simple design which provides increased light and can be manufactured and sold at relatively low cost. The low wattage lamp used in the nightlight can be either an incandescent bulb or a light emitting diode (LED) such as an ultrabright white LED either as a single bulb or a cluster of 2 or more bulbs. A photo sensitive circuit can be provided to automatically energize the incandescent bulb or the LED during low light conditions. When an LED is use as the light source, the LED is energized by a new improved power supply that is both simple in design and more efficient in operation than the standard power supply circuit used for LED's.

A nightlight provides 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 illumination 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 substantially 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, which can be selected to automatically decrease by the user. Meanwhile, the wake-up mode produces substantially full spectrum light at approximately 1,600 lumens. The controls allow a person to control the various light modes. 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 such as a display for displaying the time or alarm time. The alarm function may be provided by illumination of one of the three nightlight's illumination modes, which is preferably the wake up mode which may illuminate slowly or substantially immediately to full brightness.
