Abstract
Provided is a vehicle lamp having a lighting unit disposed inside a lighting body constituted by a housing and an outer lens, the lighting unit includes a light source and a light guide body, some of light guided by the light guide body is emitted toward a front side of the outer lens to cause a first emission region to emit light, and some of the light guided by the light guide body is emitted toward an outer circumferential edge portion of the outer lens to cause a second emission region to emit light.
Claims5
A vehicle lamp having a lighting unit disposed inside a lighting body constituted by a housing having an opening in a front surface side of the housing, and an outer lens configured to cover the opening of the housing,
- wherein the lighting unit includes a light source, and a light guide body configured to guide the light emitted from the light source,
- the light guide body includes a first light guide part in which a base end of the first light guide part faces the light source and the first light guide part extends from the base end of the first light guide part toward a front side of the outer lens,
- wherein the first light guide part includes:
- an incidence part that faces the light source at the base end of the first light guide part and into which the light emitted from the light source enters;
- a first inclined reflective surface formed at the base end of the first light guide part which is opposite to a side in which the incidence part is located,
- a first emission part that is provided at a tip of the first light guide part located at an opposite side, of the first light guide part, from the base end of the first light guide part and that is configured to emit the light toward the front side of the outer lens;
- and
- a second emission part that is located adjacent to the first inclined reflective surface at a position facing the incidence part in the base end of the first light guide part and at a position facing an outer circumferential edge portion of the outer lens, and that is configured to emit the light toward the outer circumferential edge portion of the outer lens,
- some of the light guided in the first light guide part from the incidence part is reflected at the first inclined reflective surface toward the first emission part and is emitted toward the front side of the outer lens from the first emission part to cause a first lens emission surface of the outer lens to emit light, and
- some of the light guided in the first light guide part from the incidence part is emitted toward the outer circumferential edge portion of the outer lens from the second emission part to cause a second lens emission surface of the outer lens to emit light.
