DISCHARGE LAMP OPERATING DEVICE

摘要

A discharge lamp operating device comprises an inverter (2) for converting a DC voltage into a high-frequency voltage, N discharge lamps (11 to 14) (N is a positive integer), and N+1 transformers (T1 to T5). Between the output terminals (M1, M2) of the inverter (2), an n-th discharge lamp (n=1, 2, ..., N), the primary winding of an (n+1)-th transformer, and the secondary winding of an n-th transformer are connected in series. The primary winding of the first transformer and the secondary winding of an (N+1)-th transformer are connected in series.
