  • Patent number: 8439537
    Abstract: A vehicular lighting fixture unit can include a projector lens placed on an optical axis extending in a vehicle front-rear direction. A light-emitting element can be placed between the projector lens and a rear-side focal point of the projector lens at a position lower than the optical axis so as to emit light substantially vertically upward. A phosphor can be placed so as to be closer to a vehicle rear side than the rear-side focal point. A first reflecting surface can reflect the light from the phosphor so as to condense the light toward the optical axis. A second reflecting surface can be placed substantially vertically above the light-emitting element at a position at which the second reflecting surface does not block the reflected light from the first reflecting surface. The second reflecting surface can reflect the light from the light-emitting element toward the phosphor.
