Patent ID: 7316495

Claim:
A headlight comprising: a plurality of lighting device units; and a unit support member that supports the plurality of lighting device units, wherein each lighting device unit includes: a projection lens; a light emitting diode arranged behind a rear side focus of the projection lens; and a rectilinear propagation blocking member that is arranged in a vicinity of the rear side focus, and blocks a rectilinear propagation of a portion of light emitted from the light emitting diode so as to form a cutoff line, wherein the projection lens and the rectilinear propagation blocking member are integrally formed as a light control member in each lighting device unit, wherein each lighting device unit is supported on the unit support member by individually attaching the light control member and the light emitting diode to the unit support member, the light control member being attached to the unit support member by attaching the rectilinear propagation blocking member to the unit support member, and wherein respective light control members of the plurality of lighting device units are individually attached to the unit support member, wherein an optical axis of the light emitting diode is perpendicular to an optical axis of the projection lens.
