Power supply for driving lamp using separated board

The present invention uses a separate substrate capable of mounting an inverter transformer to the main substrate, by passing the lamps driven from the inverter transformer power through the auxiliary substrate to prevent corona discharge or arc discharge between the high pressure region and the panel of the inverter transformer relates to a lamp driving power supply device for, components having a mounting face, for converting the input power source having a voltage level set in advance in the component-mounting the power supply for the lamp drive with a high voltage level than the voltage level of the input power mounted on the part mounting face of the main substrate and the main board mounting a transformer, the separator plate comprises a secondary substrate having a delivery terminal for delivering to the lamp driving power to the lamp for from the transformer to provide a power supply for the lamp drive to use.
