摘要： A lamp according to an embodiment includes a plurality of light-emitting sections including a plurality of kinds of light-emitting elements provided side by side in a predetermined direction on a substrate and configured to respectively emit lights of different colors, luminous fluxes of the lights respectively emitted by the light-emitting elements being separately controllable. The lamp according to the embodiment includes a pipe configured to diffuse the lights emitted by the light-emitting elements and formed including a translucent material, linear transmittance of which is any value of 0% to 50%. A distance “d” from a lower part of the pipe to the light-emitting elements is larger than the inner radius of the pipe.

摘要： A vehicle luminaire may include: an attachment portion which includes a concave portion opening to one end face; a light-emitting module, which includes a substrate and at least one light-emitting element provided on the substrate, provided inside the concave portion; and a plurality of bayonets provided on an outer side surface of the attachment portion. When the attachment portion is viewed from a direction along a center axis of the attachment portion, the bayonets are provided at a predetermined interval. The attachment portion includes an opening portion provided in a region between the plurality of bayonets. An opening dimension of the opening portion is larger than a width dimension of each bayonet.

摘要： A vehicle lighting device includes: a socket; a substrate, provided on a side of an end part of the socket; light-emitting elements, provided on the substrate; a frame part, having a frame shape, provided on the substrate, and surrounding the light-emitting elements; and a sealing part, provided on an inner side of the frame part and covering the light-emitting elements. When viewing from a direction along a central axis of the vehicle lighting device, a profile of the frame part is square or circular. If the profile of the frame part is square, a dimension of a side on the inner side of the frame part is 3.2 mm or more and 4.8 mm or less. If the profile of the frame part is circular, an inner diameter of the frame part is 4.5 mm or more and 6.8 mm or less.

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.
