A rotation light source lamp system is combined with a rotation light source device in which a chromatic aberration correction unit obviates focal distance differences occurring between incident paths “a” of lights emitted by LED light sources sequentially synchronized and turned on when first to N-th LED chips arrive at a location where each LED chip faces a signal transmitter while the first to N-th LED chips are rotated once in response to the application of a lamp turn-on signal for the vehicle from the signal transmitter. Chromatic aberration can be reduced by correcting a difference between refractive indices for each wavelength having a different color in the first to N-th LED chips.

The present disclosure relates to a vehicle lighting system, and discloses a vehicle lighting device. The vehicle lighting device includes a bracket, a plurality of rotating arms and a plurality of lighting modules. The rotating arms include driving columns and rotating shafts; the plurality of lighting modules are mounted on the plurality of rotating arms respectively, and the rotating shafts are rotationally mounted on the bracket, so that the rotating arms can be independently driven by the driving columns to rotate around the rotating shafts; and the rotating shafts are horizontally arranged in parallel. The lighting modules can independently and synchronously rotate up and down, the adjustment range of a light pattern position is wide, an occupied space in a headlight is small, and control is convenient. The present disclosure further discloses a vehicle headlight including the vehicle lighting device, and a vehicle.
