摘要： A vehicle lighting device includes a socket, a substrate, at least one light emitting element, a frame part, a sealing part, and a lens. The substrate is provided on one end side of the socket. The light emitting element is provided on the substrate. The frame part surrounds the light emitting element. The sealing part is provided on an inner side of the frame part and covers the light emitting element. The lens is provided on the sealing part and includes an optical part into which a light emitted from the light emitting element enters. The optical part includes a first portion from which the light entered is emitted. The first portion protrudes to a side opposite to a sealing part side. A contour of the first portion is a substantially rectangular shape as viewed from a direction along a central axis of the optical part.

摘要： 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.

摘要： A vehicle lighting device and a vehicle lamp are provided. The vehicle lighting includes a socket; a substrate provided on one end portion side of the socket; light emitting elements provided on the substrate; and a control element provided on the substrate and electrically connected to the light emitting elements. The control element turns on some of the light emitting elements when the input voltage is lower than a first voltage; turns on all of the light emitting elements when the input voltage exceeds a second voltage higher than the first voltage; and turns on all of the light emitting elements and changes at least one of total luminous flux of the light emitting elements and current flowing through the light emitting elements according to the input voltage when the input voltage is equal to or higher than the first voltage and equal to or lower than the second voltage.
