Vehicle light

摘要

A vehicle light can allow light to be emitted more uniformly through an elongated area from a fewer number of light sources as compared with a conventional one. The vehicle light can include an outer lens, a plurality of light sources arranged along the outer edge of the outer lens for emitting light in an optical axis direction orthogonal to the arraying direction thereof, an inner lens including a light guide portion elongated in the arraying direction of the light sources and disposed along the optical axis of the light sources, for dispersing the light in a longitudinal direction of the lens and emitting in the optical axis direction, and a first diffusion reflector and second diffusion reflectors configured to be elongated in the longitudinal direction of the inner lens and disposed in the optical axis direction of the lens.

1. A vehicle light, comprising:
a plurality of light sources arranged in a predetermined array direction, each light source having an optical axis orthogonal to the array direction, and each light source configured to emit light in a direction of the optical axis; a lens elongated in the array direction and disposed along the optical axis of the plurality of light sources, the lens configured to transmit light emitted from the plurality of light sources in the optical axis direction, the light being dispersed in a longitudinal direction of the lens; and a diffusion reflector elongated in the longitudinal direction of the lens and disposed along the optical axis of the lens, the diffusion reflector configured to diffuse and reflect light emitted from the lens, wherein the lens includes a plurality of light guide blocks associated with the plurality of light sources and coupled in the longitudinal direction of the lens, and the plurality of light guide blocks each include:
an incidence face opposed to a respective one of the light sources;a first reflecting face configured to internally reflect light in the longitudinal direction of the lens, the light having passed through the incidence face into the light guide block;a plurality of second reflecting faces configured to internally reflect light in the optical axis direction of the lens, the light having been internally reflected from the first reflecting face, those of the second reflecting faces located farther away in the longitudinal direction of the lens from the light source opposed to the incidence face being arranged to be more aligned with the optical axis direction; andan emission face configured to allow the light internally reflected from the plurality of second reflecting faces to be projected out of the light guide block.
