Abstract (en)
[origin: EP2408265A2] A vehicle headlamp system (100) includes a lamp device (12; 22) and a control device (14) to control the brightness thereof while in operation. The lamp device includes at least a first light emitting diode unit (126; 226; 326) providing a first color temperature, and at least a second light emitting diode unit (128; 228; 328) providing a second color temperature different from the first color temperature. The control device is coupled to the lamp device for changing the brightness ratio of the second LED unit to the first LED unit and controlling the resulting color temperature of the lamp device.
