Rotation light source lamp system for reducing chromatic aberration and vehicle using the same
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.
