A night light is made to operate conveniently from a house current by converting the current to lower voltage for efficient automatic operation of a suitable LED light, or other suitable small light, for response to ambient light. An almost instantaneous response to an ambient light is provided by a circuit formed of readily available standard components guided in this instance by cooperation of a photocell which responds to a light ray to direct a Schmitt-trigger Inverter to operate a super-bright LED lamp. Circuitry is placed upon a printed circuit board upon a plastic housing for safety and convenience. |
