1. A vehicular headlamp apparatus comprising:
- (i) a first light-emitting portion that forms a base beam by reflecting light from a first light source;
(ii) a second light-emitting portion that forms a second light beam by reflecting light from a second light source, a light distribution of the second light beam supplements a light distribution of the base beam; and
(iii) a light emission control means for varying the light distribution of the second light beam formed by adjusting the light distribution formed by the second light-emitting portion based on travel environment information,wherein the light distribution of the base beam is used as a low beam and wherein a light distribution of part of a high beam is used for irradiating a forward field of the vehicle in a wide range and further wherein the second light beam is formed by using a peripheral zone of a reflective surface of a reflector.

Abstract
A vehicular headlamp apparatus 1 is provided with a first and a second light-emitting portion including a common light source 3 or a plurality of light sources 3 and 3′. The first light-emitting portion 2_1 forms a base beam by normally lighting the light source 3 to use emission light from the light source. The second light-emitting portion 2_2 is caused to emit an auxiliary beam for supplementing the light distribution of the base beam made available by the first light-emitting portion 2_1. The distribution, the quantity of light or light color of the light emitted from the first light-emitting portion 2_1 is varied with the travel condition or travel environment of a vehicle.
