Light driver arrangements for vehicle headlamps

A vehicle headlamp system comprising:

• a plurality of low beam LEDs;
• a plurality of high beam LEDs;
• the plurality of low beam LEDs and the plurality of high beam LEDs being a part of a light source for a single headlamp assembly;
• a first light driver;
• a second light driver;
• and
• the first light driver and the second light driver being configured to selectively provide electrical energy to power the plurality of low beam LEDs and the plurality of high beam LEDs in a commingled manner.

A method of operating a vehicle headlamp system, the vehicle headlamp system including a plurality of low beam light sources and a plurality of high beam light sources, the method comprising:

• receiving a signal to operate the vehicle headlamp system in one of a low beam operational mode or a high beam operational mode;
• responsive to the received signal being a signal to operate the vehicle headlamp system in the low beam operational mode, causing, using a controller, a first light driver to supply electrical energy to a first group of low beam light sources while bypassing a first group of high beam light sources, and causing, using the controller, a second light driver to supply electrical energy to a second group of low beam light sources while bypassing a second group of high beam light sources, whereby the plurality of low beam light sources are activated and the plurality of high beam light sources are not activated;
• and
• responsive to the signal being a signal to operate the vehicle headlamp system in the high beam operational mode, causing, using the controller, the first light driver to supply electrical energy to the first group of low beam light sources and the first group of high beam light sources in series, and causing, using the controller, the second light driver to supply electrical energy to the second group of low beam light sources and the second group of high beam light sources in series, whereby the plurality of low beam light sources are activated and the plurality of high beam light sources are activated.
