MULTI-LAMPS DRIVER

摘要

PURPOSE: A multi lamp driver is provided to reduce a circuit area and manufacturing cost by maintaining current balance of a plurality of lamps through one transformer. CONSTITUTION: A first current balance unit(120) transmits the AC power for driving a lamp to a lamp unit(140). The first current balance unit maintains the balance of the current inputted to the lamp unit. A second current balance unit(130) is arranged between the first current balance unit and the lamp unit. The second current balance unit maintains the balance of the current inputted to the lamp unit. The lamp unit includes first to N-th lamp groups. The first and N-th lamp groups receive the AC power for driving the lamp from the second current balance unit in parallel. Each lamp group is comprised of a plurality of lamps.
