Patent ID: 8092059

Claim:
A vehicular lighting fixture having a light emitting axis, comprising: a projection lens having a focus; a light source configured to emit irradiation light in an irradiation direction; a shade located between the projection lens and the light source, the shade including an upper surface and an end edge facing towards the projection lens, wherein the end edge of the upper surface of the shade is located substantially at the focus of the projection lens; a first reflection surface located in the irradiation direction of the irradiation light emitted from the light source and configured such that at least a portion of the irradiation light is reflected by the first reflection surface and is condensed substantially at the end edge of the shade and then passes through the projection lens to form a basic light distribution pattern having a cutoff line defined by the end edge on a projection plane; a second reflection surface includes one planar reflection surface formed on a lower surface of a step section of the upper surface of the shade, the second reflection surface configured such that at least a portion of light reflected from the first reflection surface is reflected by the second reflection surface and passes through the projection lens to form a first additional light distribution pattern which has the cutoff line defined by the end edge and is superimposed on the basic light distribution pattern; a third reflection surface located on a higher surface of the step section of the upper surface of the shade and extending along the end edge of the shade, the third reflection surface configured such that at least a portion of light reflected from the first reflection surface is reflected by the third reflection surface and passes through the projection lens to form a second additional light distribution pattern which extends along the cutoff line and which is superimposed on the basic light distribution pattern; and a fourth reflection surface located on the upper surface of the shade and inclined obliquely from the third reflection surface to the second reflection surface so as to connect the second reflection surface and third reflection surface, the fourth reflection surface configured such that at least a portion of light reflected from the first reflection surface is reflected by the fourth reflection surface in a direction not incident on the projection lens.
