Abstract (en)
[origin: EP2568773A2] The present invention relies on polyphase alternating current power with phase difference or direct current power rectified from polyphase alternating current power to drive a common -electric-driven luminous body, or to separately drive adjacently installed individual electric-driven luminous bodies so that the pulsation of the outwardly projected light is reduced.
