Patent ID: 8664876

Claim:
A lighting device with optical pulsation suppression by polyphase-driven electric energy, said lighting device being supplied with electric power from a three-phase, three wire, Y-connected, alternating current power line including a first wire (R), a second wire (S), a third wire (T), and a common Y connection point, comprising: a first electric energy-driven luminous body ( 101 ) having a first terminal connected to the first wire (R) of the three-phase power line through a first impedance device ( 1000 ), and a second terminal connected to the common Y connection point; a second electric energy-driven luminous body ( 102 ) having a first terminal connected to a second wire (S) of the three-phase power line through a second impedance device ( 1000 ), and a second terminal connected to the common Y connection point; a third electric energy-driven luminous body ( 103 ) having a first terminal connected a third wire (T) of the three-phase power line through a third impedance device ( 1000 ), and a second terminal connected to the common Y connection point.
