Kind Code:

A1

Abstract:

Provided is a vehicular lighting device that can form a plurality of types of light distribution patterns. A vehicular lighting device that comprises: a first light-guiding lens that includes a first light entry surface and a first light exit surface; a second light-guiding lens that is arranged below the first light-guiding lens and includes a second light entry surface and a second light exit surface; a first light source that emits light that enters from the first light entry surface and exits from the first light exit surface; a second light source that emits light that enters from the second light entry surface and exits from the second light exit surface; and a projection lens that inverts and projects intensity distributions that are formed on the first and second light exit surfaces. A lower end edge of the first light exit surface includes a stepped first edge part and a first extended edge part that is arranged on at least one side of the first edge part. An upper end edge of the second light exit surface includes a stepped second edge part that is the same shape as the first edge part but inverted and a second extended edge part that is arranged on at least one side of the second edge part. The first and second light-guiding lenses are arranged such that the first and second edge parts are in line contact and such that a gap is formed between the first and second extended edge parts.
