A headlight having an ellipse group reflecting surface as a main reflecting surface
and a projection lens further includes a second reflecting surface, a third reflecting
surface, and a ring-shaped lens. Direct light from a light source reaching to a
space between the main reflecting surface and the projection lens is reflected
by the second reflecting surface backward. The reflected light from the second
reflecting surface is further reflected by the third reflecting surface, and then
is adjusted with the ring-shaped lens. Light directly emitted from the light source
and being ineffective in the conventional headlight can be collected using the
second and third reflecting surfaces, and forwarded in an illumination direction
by passing through the ring-shape lens such that the shape of the light is controlled
to provide an appropriate shape, thereby contributing to the formation of light
distribution characteristics and increase in the light intensity.
