发明名称 Vehicular headlamp having improved yield of high-beam luminous energy
摘要 A vehicular headlamp provided with a reflector composed of a low-beam reflecting surface and a high-beam reflecting surface disposed closely adjacent vertically one another, which headlamp provides a high yield of high-beam luminous energy. The reflector is formed so that the focal distance of the lower, high-beam reflecting surface is less the focal distance of the upper, low-beam reflecting surface so as to increase the solid angle defined by the high-beam reflecting surface. Preferably, the rear end portion of the high-beam reflecting surface is displaced rearward of a rear end portion of the low-beam reflecting surface, thus further increasing the solid angle of the high-beam reflecting surface.
