Headlamp apparatus
A headlamp apparatus may include: a light source configured to emit light; a reflector having a reflecting surface with different curvatures in first and second directions crossing each other, and configured to reflect the light emitted from the light source; and a lens configured to receive the light through the reflector, and change the magnification of the light so as to guide the light to the front.
1. A headlamp apparatus comprising:
a light source configured to emit light;
a reflector comprising a reflecting surface having different curvatures in first and second directions crossing each other, and configured to reflect a light emitted from the light source; and
a lens configured to receive the light through the reflector, and change a magnification of the light so as to guide the light through a front of the headlamp apparatus;
wherein the light source comprises a plurality of LED light sources, and each of the LED light sources is separately activated.
2. The headlamp apparatus of claim 1 , wherein the plurality of LED light sources is arranged in a matrix shape.
3. The headlamp apparatus of claim 1 , wherein the reflecting surface forms a concavely curved surface toward the light source, and
a second curvature radius in the second direction is larger than a first curvature radius in the first direction.
4. The headlamp apparatus of claim 3 , wherein the first direction is a top-to-bottom direction with respect to the reflecting surface, and the second direction is a side-to-side direction with respect to the reflecting surface.
5. The headlamp apparatus of claim 1 , wherein the lens comprises:
a first lens facing the reflector; and
a second lens connected to the first lens, and formed in a convex shape so as to have different curvatures in third and fourth directions crossing each other.
6. The headlamp apparatus of claim 5 , wherein the second lens is integrated with the first lens through a forming process.
7. The headlamp apparatus of claim 6 , wherein the second lens is installed to face a surface of the first lens that is away from the reflector, and configured to be formed in a semi-circle cylindrical shape.
8. The headlamp apparatus of claim 5 , wherein the first lens forms a convexly curved surface or flat surface toward the reflector.
9. The headlamp apparatus of claim 8 , wherein a fourth curvature radius in the fourth direction is smaller than a third curvature radius in the third direction.
10. The headlamp apparatus of claim 9 , wherein the third direction is a top-to-bottom direction with respect to the second lens, and the fourth direction is a side-to-side direction with respect to the second lens.
