LAMP AND BULB FOR ILLUMINATION AND AMBIANCE LIGHTING

摘要

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 ).
