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).
