Abstract
A headlamp apparatus for a vehicle which produces a glare-free high beam may include a light source including a plurality of chips which may be arranged in line, and each of which may be separately turned on or off, a condenser lens disposed in front of the light source, and configured to improve light efficiency by condensing light emitted from the light source, a beam pattern conversion lens disposed in front of the condenser lens and configured to increase a size of a beam pattern of the light source in a vertical direction, and an optical refractive lens disposed in front of the beam pattern conversion lens, the optical refractive lens projecting the light that has passed through the beam pattern conversion lens onto a road by imaging the light onto a screen.
