EMITTING ELEMENT DRIVING DEVICE FOR LIGHTING

摘要

PURPOSE: For lighting light emitting drive device selects the minimum value of the feedback voltage value about multichannel. The cost is reduced by using one transformer. CONSTITUTION: The input rectifier(11) rectifies the input alternating current voltage. It is connected to the input rectifier and the PFC part(12) satisfies the harmonics control. The insulation type DC/DC convertor part(13) is created the drive power from the PFC part based on the applied direct current voltage.
