Abstract

Provided is a vehicular illumination device, which includes: an outer light-transmitting piece; a headlight accommodated in a housing having the light-transmitting piece; a second light source portionand a first light guide accommodated inside the housing; and a second light guide disposed outside the housing. An end surface of the first light guide and an end surface of the second light guide are disposed to face each other via an interposing portion of the outer light-transmitting piece interposed between these end surface portions. At least a part of light output from the second light source portion is incident from the first light guide to the second light guide through the interposing portion. In this way, the second light source portion can be protected from being damaged by moisture, dust and the like, light can be emitted from the outer side of the housing, and improved appearance can be realized.

Description

technical field [0001] The present invention relates to a lighting device for a vehicle, and more particularly to a lighting device including a headlight provided at the front of a vehicle and a light emitting unit attached to the headlight. Background technique [0002] In vehicles such as automobiles, headlights are provided at the front. In recent years, vehicles equipped with a plurality of light emitting units attached to headlights have been developed. [0003] For example, Japanese Patent Laid-Open Publication No. 2018-32512 (hereinafter referred to as "patent document") discloses a lighting device in which a light-emitting part attached to the headlight is provided in a housing for housing the headlight. running lights. In the lighting device disclosed in the above-mentioned patent documents, the rod-shaped light guide (light guide member) and light source (LED light source) that each daytime running lamp has are accommodated in the housing, and the light guide can...
