POWER SUPPLY FOR DRIVING LAMP USING SEPARATED BOARD

PURPOSE: A power supply unit for driving a lamp is provided to prevent an arc discharge or a corona discharge between a panel and a high voltage region of an inverter transformer by delivering a power from the inverter transformer to the lamp through a sub substrate. CONSTITUTION: A power supply uni...

Beschreibung
Zusammenfassung:	PURPOSE: A power supply unit for driving a lamp is provided to prevent an arc discharge or a corona discharge between a panel and a high voltage region of an inverter transformer by delivering a power from the inverter transformer to the lamp through a sub substrate. CONSTITUTION: A power supply unit for driving a lamp includes a main substrate(B1) and a sub substrate(B2). The main substrate has a part mounting surface. A transformer(110) is mounted on the part mounting surface, and transforms an input power into a power for driving the lamp. The sub substrate is mounted in the part mounting surface of the main substrate, and has a transfer terminal(Con) and a sensing device(C). The transfer terminal transfers the power for driving the lamp to the lamp, and is connected to a power output terminal(VH) through the sub substrate. The sensing device detects a voltage level of the power for driving the lamp.
