Abstract

A vehicle interior lighting device includes a light source disposed in a vehicle, and a rod-shaped light guiding member including an one end face through which light emitted from the light source is inputted a transparent material, and a transparent material for guiding the inputted light from the one end face to an other end in an axis direction of the rod-shaped light guiding member. The rod-shaped light guiding member includes a first light radiation section for radiating light in a direction perpendicular to the axis direction according to a first illumination pattern to illuminate a first irradiated area in the vehicle, and a second light radiation section for radiating light in the direction perpendicular to the axis direction according to a second illumination pattern different from the first illumination pattern to illuminate a second irradiated area in the vehicle.

Description

[0001] This application is based on Japanese Patent Application No. 2008-251891 filed on September 29, 2008, the entire contents of which are incorporated herein by reference. technical field [0002] The invention relates to an interior lighting device for illuminating different interior areas of a vehicle. Background technique [0003] A known light-emitting device includes a light source and a rod-shaped light guide extending in the light-emitting direction of the light source and having an upper surface as a reflective surface and a lower surface as a light-emitting surface (see, for example, JP-A-2007 -179962). The light emitting device is configured such that the reflective surface of the rod-shaped light guide is provided with reflective grooves at predetermined intervals in the extending direction of the rod-shaped light guide, and among these reflective grooves, the reflective grooves close to the light source are formed on the non-reflective surface. The area outs...
