Abstract:
1. A vehicle lighting device, comprising: a lamp unit for concentrating light; a lamp unit for diffusion; a lamp housing and a lamp lens, partitioning a lamp room; and an optical-axis adjuster which is integrally mounted in the lamp housing in an optical-axis adjustable manner in a state in which the lamp unit for concentrating light and the lamp unit for diffusion are integrally disposed in the lamp room, wherein the lamp unit for concentrating light is comprised of: a first reflecting surface which is an elliptical reflecting surface; a semiconductor-type light source disposed at or near a first focal point of the first reflecting surface; and a parabolic reflecting surface for controlling reflected light from the first reflecting surface and reflecting the controlled reflected light on a road surface, as a light distribution pattern for concentrating light, and wherein: the lamp unit for diffusion is comprised of: a first reflecting surface which is an elliptical reflecting surface; a semiconductor-type light source disposed at or near a first focal point of the first reflecting surface; and a parabolic reflecting surface for controlling reflected light from the first reflecting surface and reflecting the controlled reflected light on a road surface, as a light distribution pattern for diffusion.
