Patent ID: 7370998

Claim:
A lighting fixture unit that emits white light in upper beam irradiation of a vehicular headlamp and emits infrared light in lower beam irradiation of the vehicular headlamp, said lighting fixture unit comprising: a light source part including a first semiconductor light-emitting element for emitting said white light and a second semiconductor light-emitting element for emitting said infrared light; an optical member for irradiating in a forward direction the white light from the first semiconductor light-emitting element or the infrared light from the second semiconductor light-emitting element; and optical axis adjusting means for changing in a vertical plane a direction of an optical axis related to the first and second semiconductor light-emitting elements; wherein: the first semiconductor light-emitting element comprises a light-emitting diode, the second semiconductor light-emitting element comprises a light-emitting diode, the first semiconductor light-emitting element is positioned higher than the second semiconductor light-emitting element, the first and second semiconductor light-emitting elements are positioned in close proximity on a same board, and said white light or infrared light passes through a lens, is emitted forward, and has its irradiation direction adjusted upward in upper beam irradiation compared with its irradiation direction in lower beam irradiation.
