Abstract: A vehicular light is provided which is capable of forming an emission pattern with a good appearance at the time of lighting. The vehicular light has a light guide body having a light guide portion and a slit that penetrates the light guide portion in its thickness direction and linearly extend along a light guide path of light rays emitted from a plurality of LED light sources and guided within the light guide portion. The slit is composed of three regions including a constant width region formed in a predetermined length range toward the distal end, a tapered width region gradually narrowing toward the distal end, and a distal end region having a distal end of a curved surface shape formed in the distal end portion of the tapered width region.

Abstract: An interior lamp can achieve both an excellent illumination function and an excellent illumination effect (providing a comfortable environment) and may possibly provide high merchandizability characteristics. The interior lamp can include an LED light source unit having a substrate and a plurality of white LED lamps and colored LED lamps mounted on the substrate. A cover case can be provided to serve as a light illumination unit. The light illumination unit can include a double-layer structure having a light diffusion layer and a light transmission layer. The light diffusion layer can have a plurality of penetrating holes. The light transmission layer can have a plurality of convex lens portions. The center axes of the penetrating holes and the corresponding lens portions can coincide with corresponding optical axes of the white LED lamps, respectively.
