Abstract
A headlamp in which a right elliptic reflecting surface and a left elliptic reflecting surface are provided on a position toward an upper front portion of the bulb, a right parabolic reflecting surface is provided on a position toward a right lower portion of said main reflecting surface, and a left parabolic reflecting surface is provided on a position toward a left lower portion of said main reflecting surface, whereby waste light can be recovered and used as irradiating light. A headlamp in which the elliptic reflecting surfaces which capture light emitted upwardly and forwardly from the bulb and parabolic reflecting surfaces which reflect said light in a desired direction are provided. A light-distribution varying means is provided in the optical path of the parabolic reflecting surfaces, whereby it becomes possible to switch between light distributions.
