ABSTRACT:
Disclosed is a novel apparatus and method that combines a nightlight and an air freshener in a single device. The apparatus includes circuitry where a single resistor heats a heating block that heats and releases a volatile aromatic. The resistor also limits the current that passes through one or more light emitting diodes. The aromatic may be liquid scented oil held by a container. The container may also include a protruding wick that is heated by the heating block to facilitate oil evaporation. The light emitting diodes illuminate the housing and a decorative shield. The diodes may also illuminate fiber optic cables. The apparatus receives alternating current from a standard wall outlet. The circuitry utilized by the device ensures that the resistor is continuously powered during both half-cycles of the alternating current resulting in optimal heating of the aromatic.
