Abstract
A chromaticity variable type road projection lamp system applied to a vehicle is composed of a chromaticity variable lamp that radiates a road surface radiation content, which is generated by reflecting the lights emitted from a first projection light-emitting diode (LED) of a warm white color and a second projection LED of a cool white color disposed in the direction symmetrical to a DMD at the tilting angle, with a projection beam from a chromaticity variable road projection, and radiates the low beam by comparing the warm white color of the first lamp LED and the cool white color of the second lamp LED with the road surface radiation content in chromaticity.
