Diffuser with light emitting diode nightlight

摘要

An electrically operated diffuser has a fragrance-emitting element ( 8 ) for facilitating diffusion of an active material, and at least one light emitting diode ( 7 ). The at least one light emitting diode ( 7 ) serves as a nightlight and has a luminous intensity rating of at least about 5000 mcd at 20 mA. Also, the at least one light emitting diode ( 7 ) may be positioned at a back surface of the diffuser, such that when an active material is received in the compartment the at least one light emitting diode ( 7 ) shines through the active material. The diffuser may include a remote-use assembly to supply power to the diffuser from a wall socket remote from the diffuser. The diffuser may also include a light controller to change one or more of the color and the intensity of the at least one light emitting diode ( 7 ).
