Light driving system for indiviual control of multi-light source and method thereof

摘要

The present invention relates to a light source operating system of a vehicle, comprising: a light source unit comprising a plurality of light sources; and a light source operating unit individually operating the light sources of the light source unit. The light source operating unit and the light source unit transmit and receive control data individually controlling the light sources of the light source unit as serial data through communication. The light source unit individually controls the light sources by using control data. The light source driving unit is characterized by comprising a power control unit controlling such that a current flowing in the light sources of the light source unit may flow in a uniform manner, thereby reducing the number of wires individually controlling the plurality of light sources.
