Abstract
A load drive (1) having a pulse converter (2) and a DC/DC converter (5). The pulse converter (2) is capable of converting a high DC voltage supplied from the power supply unit (10) of a vehicle to a pulse voltage and applies the pulse voltage to a first lamp (L1). The DC/DC converter (5) operates to convert the high DC voltage to a low DC voltage whose voltage value is lower than the voltage value of the high DC voltage and applies the low DC voltage to a second lamp (L2).
Claims3
A load drive for supplying electric power from a power supply unit of a vehicle to first and second lamps comprising:
- a pulse converter for converting a high DC voltage supplied from the power supply unit to pulse voltage and supplying the pulse voltage to the first lamp;
- and
- a DC voltage converter for converting the high DC voltage to a low DC voltage lower than the high DC voltage and supplying the low DC voltage to the second lamp.
