SYSTEM FOR SINGLE CHANNEL BASED MULTI-FUNCTION LED LAMP DRIVE

A single channel-based multi-functional light emitting diode lamp driving system includes: first and second light source groups distinguished for each lamp function thereof; a single LED lamp driving module adjusting an input voltage to a voltage required for each lamp function and to apply it to the first and second light source groups; a switching module controlling on or off of the first and second light source groups; and a control module controlling light amounts of the first and second light source groups by performing time-division control on an on or off time of the switching module in conjunction with the LED lamp driving module, wherein the control module is configured to perform time division turn-on control on the first and second light source groups by controlling at least one of a current value applied to the first and second light source groups or a duty ratio thereof in a high-beam passing mode.
