Abstract
A vehicle lighting device includes: 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 a lamp unit for diffusion are integrally disposed in the lamp room. The lamp unit for concentrating light radiates a light distribution pattern for diffusion. The lamp unit for diffusion radiates a light distribution pattern for diffusion. As a result, in this vehicle lighting device, one lamp unit for concentrating light is provided which satisfies a main light distribution standard and forms a light distribution pattern for concentrating light as a standard for optical axis, thereby facilitating adjustment of light distribution and allowing for precise adjustment of light distribution.
