Patent ID: 11767962

Abstract:
A vehicle lighting device includes a socket; a substrate; and one first and four second light emitting elements. A square luminance distribution region is defined on light irradiation sides of first and second light emitting elements. A center of distribution region overlaps central axis of device. Distribution region is equally divided into four square first regions whose corners overlap center of distribution region. Each of first regions is equally divided into nine square second regions. A length of one side of second region is 0.8 mm. Luminance of distribution region is 90% or more of a total luminance of light emitted from device. In twenty second regions arranged along sides of distribution region, luminance of one second region is 2% or less of total luminance. In sixteen second regions provided inside twenty second regions, luminance of one second region is 3% or more and 10% or less of total luminance.
