Abstract: An Edison-style light bulb (40) which supports a plurality of light emitting diodes (LEDs) (50) and an illumination source (54). First and second electrical circuits (56) and (58) are mounted in the bulb to supply electrical power to the illumination source and to the LEDs. A switch circuit (60) is connected to control the supply of electrical power to the first and second electrical circuits (56) and (58) to adjust and coordinate the light output from the LEDs (50) and from the illumination source (54).

Abstract: A novel apparatus for producing combined presentation of light and aroma to produce a desired overall sensory effect. The includes a fragrance dispenser (31), a light source (42), an audio system (52), and a microprocessor (99). The fragrance dispenser (31) is refillable and controllable, so as to adjust the rate at which the fragrance dispenser dispenses a fragrance. The light source (42) comprises a plurality of LEDs (40a-40c) of at least two different colors and is controllable so as to adjust the operation of the plurality of LEDs (40a-40c). The audio system (52) controls sounds to be emitted from the apparatus. The microprocessor (99) controls the rate at which the fragrance dispenser (31) dispenses fragrance and the operation of the light source (42) and audio system (52).
