Abstract
A vehicular projector headlamp includes: a projection lens; a first LED element and a second LED element that are light sources and that are arranged on opposite sides of an optical axis of the projection lens so as to substantially face each other; a first reflector that has a first reflective surface having a first focal point located at the first LED element and a second focal point located in proximity to a rear focal point of the projection lens; and a second reflector that has a second reflective surface having a first focal point located at the second LED element and a second focal point located in proximity to the rear focal point of the projection lens, wherein the second reflective surface faces the first reflective surface.

A vehicular projector headlamp comprising:
- a projection lens;
- a first LED element and a second LED element that are light sources and that are arranged on opposite sides of an optical axis of the projection lens so as to substantially face each other;
- a first reflector that has a first reflective surface having a first focal point located at the first LED element and a second focal point located in proximity to a rear focal point of the projection lens;
- and
- a second reflector that has a second reflective surface having a first focal point located at the second LED element and a second focal point located in proximity to the rear focal point of the projection lens, wherein the second reflective surface faces the first reflective surface.
A vehicular projector headlamp comprising:
- a projection lens;
- a first LED element;
- a second LED element;
- a first reflector that has a curved first reflective surface having a first focal point located at the first LED element and a second focal point located in proximity to a focal point of the projection lens;
- and
- a second reflector that has a curved second reflective surface having a first focal point located at the second LED element and a second focal point located in proximity to the focal point of the projection lens, wherein the second reflective surface faces the first reflective surface, wherein
- the first LED element emits light in a direction to approach the second LED element so that the emitted light strikes the first reflective surface,
- the second LED element emits light in a direction to approach the first LED element so that the emitted light strikes the second reflective surface, and
- the focal point of the projection lens is a focal point adjacent to the first reflector and the second reflector.
