Abstract

A self-contained night light is disposed in a housing containing spaced-apart male AC prongs the mate with an AC socket. The housing contains an array of differently colored, preferably light emitting diode. Light sources that can dynamically output different patterns of differently colored light in response to drive signals. A microcontroller executes a sequence of instructions causing the controller to output different sequences of signals that are coupled to a driver unit that drives the light sources. The result is that the array dynamically produces different patterns of differently colored light. A user operable control allows a viewer to “freeze” any desired pattern of light, such that until reset, the night light will continue to output a static pattern of colors. The night light may include a manual or light-sensing ON/OFF switch.
