Problems solved by technology

[0008] However, in each of the above-mentioned conventional lighting devices for vehicles, since any of the positions of the floor surface irradiation parts are far from the floor surface, it is not possible to irradiate the floor surface with sufficient illuminance.
In addition, because the position of the floor surface irradiation unit is far away from the floor surface, the light path may be blocked by intermediate objects such as instrument panels and seats, and it may not be possible to ensure the illumination of the floor surface.
[0009] In the vehicle lighting devices of Patent Document 1 and Patent Document 2, the floor surface around the user's side when sitting can be illuminated, but the floor surface around the user's side when getting on and off the vehicle cannot be ensured.

Abstract

The present invention provides a lighting device for a vehicle that can sufficiently illuminate a floor in a cabin without illuminance reduction due to an object such as an instrument panel or a seat disposed between the lighting device and the floor, and can surely illuminate the floor around a user's feet when the user is getting in or off the vehicle. An inner sill lighting device (11) for lighting the floor in the cabin is arranged at the side of a cabin surface (7a) of an inner sill cage (7).

Description

technical field [0001] The present invention relates to a lighting device for a vehicle, in particular to floor lighting in a vehicle compartment. Background technique [0002] As a vehicle lighting device, various devices for illuminating the floor surface in a vehicle compartment have been proposed conventionally. Patent Document 1 and Patent Document 2 disclose techniques for providing a floor surface irradiation unit under an instrument panel. Patent Document 3 discloses a technique in which a floor surface irradiation unit is provided on a steering wheel cover. [0003] prior art literature [0004] patent documents [0005] Patent Document 1: Japanese Publication No. 58-124346 [0006] Patent Document 2: Japanese Patent Application Laid-Open No. 4-129856 [0007] Patent Document 3: Japanese Patent Application Publication No. 6-33738 [0008] However, in each of the conventional vehicle lighting devices described above, the floor surface cannot be irradiated with ...
