ABSTRACT:
A light device includes a nightlight unit adapted to operate in an automatic mode, an on mode, or an off mode; an illumination unit comprising a sensor, the illumination unit being removably secured to the nightlight unit; and a charging unit for charging the illumination unit. The lighting unit is adapted to come on automatically by operating in the automatic mode, continuously emit light by operating in the on mode, or stop emitting light by operating in the off mode. The illumination unit is adapted to come on automatically to emit light either when the sensor senses an activating condition in the form of an absence of AC or after removing from the nightlight unit. The sensor is adapted to disable the illumination unit either when sensing a termination of the activating condition or after placing the illumination unit in the nightlight unit and electrically connecting thereto.
