Automotive headlamp apparatus
First Claim
1. An automotive headlamp apparatus comprising:
- a light source in which a plurality of semiconductor light-emitting elements are arranged at intervals from each other; and
a projection lens configured to project light, emitted from the light source, toward a front area of a vehicle as a light source image,wherein the semiconductor light-emitting elements are located in front of a focal point of the projection lens.

Abstract
An automotive headlamp apparatus includes a light source, in which a plurality of LED chips are arranged at intervals from each other, and a projection lens for projecting the light, emitted from the light source, toward a front area of a vehicle as a light source image. The semiconductor light-emitting elements may be located within than a focal point of the projection lens. The LED chip is arranged such that the light emitting surface of the LED chip faces the front area of the vehicle. The light emitting surface of the LED chip may be of a rectangular shape and the LED chip may be arranged such that a side of the light emitting surface is at a slant with respect to the vehicle width direction.
