Abstract

Official abstract text for this publication.

A lighting device includes a first light source portion, a light guide that includes a light guide body with an elongated shape, guides light incident from the first light source portion in a longitudinal direction of the elongated shape, and emits a first light including the guided light to illuminate an illuminated object, and a second light source portion that emits a second light to illuminate the illuminated object. The second light source portion is provided independently of the first light source portion and the light guide.

First claim

Opening claim text (preview).

The invention claimed is: 1. A lighting device, comprising: a first light source portion; a light guide that comprises a light guide body with an elongated shape, guides light incident from the first light source portion in a longitudinal direction of the elongated shape, and emits a first light comprising the guided light to illuminate an illuminated object; and a second light source portion that emits a second light to illuminate the illuminated object, wherein the second light source portion is provided independently of the first light source portion and the light guide, wherein the first light emitted from the first light source portion and the second light emitted from the second light portion partially overlap each other. 2. The lighting device according to claim 1 , wherein the second light source portion is provided adjacent to the light guide or the first light source portion. 3. The lighting device according to claim 1 , wherein each of the first light emitted from the first light source portion and the second light emitted from the second light portion is shone on the illuminated object through an outer lens having a light diffusion effect. 4. The lighting device according to claim 1 , wherein the light guide is arranged in a front-rear direction of a vehicle, and wherein the first light and the second light are continuously shone on an interior panel of the vehicle. 5. The lighting device according to claim 2 , wherein each of the first light emitted from the first light source portion and the second light emitted from the second light portion is shone on the illuminated object through an outer lens having a light diffusion effect. 6. The lighting device according to claim 2 , wherein the light guide is arranged in a front-rear direction of a vehicle, and wherein the first light and the second light are continuously shone on an interior panel of the vehicle. 7. The lighting device according to claim 4 , wherein each of the first light emitted from the first light source portion and the second light emitted from the second light portion is shone on the illuminated object through an outer lens having a light diffusion effect. 8. The lighting device according to claim 5 , wherein the light guide is arranged in a front-rear direction of a vehicle, and wherein the first light and the second light are continuously shone on an interior panel of the vehicle.
