Abstract

An emblem includes: a light source; a light guide through which light rays radiated from the light source are guided; an outer lens that contains a diffusion material which diffuses light rays in the outer lens, and that emits light rays by transmitting the light rays radiated from the light guide; and a housing in which the light guide is housed, to which an outer circumferential portion of the outer lens is bonded, and which has a space in which the light guide is disposed between the outer lens and the housing. The light source is disposed on an inner circumferential portion side of the outer lens when viewed from an outer lens side.

Claims (23)

1 . An emblem comprising:

a light source;

a light guide through which light rays radiated from the light source are guided;

an outer lens that contains a diffusion material which diffuses light rays in the outer lens, and that emits light rays by transmitting the light rays radiated from the light guide; and

a housing in which the light guide is housed, to which an outer circumferential portion of the outer lens is bonded, and which has a space in which the light guide is disposed between the outer lens and the housing, wherein:

the light source is disposed on an inner circumferential portion side of the outer lens when viewed from an outer lens side, and the light rays from the light source are guided to an outer circumferential portion of the light guide,

the light rays from the light source guided to the light guide are guided from the light guide to the outer circumferential portion of the outer lens, and the light rays guided to the outer circumferential portion of the outer lens are diffused in the outer circumferential portion of the outer lens and are transmitted through the outer circumferential portion of the outer lens,

the outer lens and the light guide are spaced apart from each other, and

when viewed from the outer lens side, an outer edge of the outer circumferential portion of the light guide is positioned on an inner circumferential side relative to an outer edge of the outer circumferential portion of the outer lens.

2 . An emblem comprising:

a light source;

a light guide through which light rays radiated from the light source are guided;

an outer lens that contains a diffusion material which diffuses light rays in the outer lens, and that emits light rays by transmitting the light rays radiated from the light guide; and

a housing in which the light guide is housed, to which an outer circumferential portion of the outer lens is bonded, and which has a space in which the light guide is disposed between the outer lens and the housing, wherein:

the light source is disposed on an inner circumferential portion side of the outer lens when viewed from an outer lens side, and the light rays from the light source are guided to an outer circumferential portion of the light guide,

the light rays from the light source guided to the light guide are guided from the light guide to the outer circumferential portion of the outer lens, and the light rays guided to the outer circumferential portion of the outer lens are diffused in the outer circumferential portion of the outer lens and are transmitted through the outer circumferential portion of the outer lens, and

a surface of the outer circumferential portion of the outer lens on a side opposite from the housing is covered with a covering layer which is able to transmit light rays.

3 . The emblem according to claim 2 , wherein the covering layer is a metallic deposition film.

4 . The emblem according to claim 1 , wherein the outer circumferential portion of the light guide is disposed along a bonding portion between the outer lens and the housing.

5 . The emblem according to claim 1 , wherein, when viewed from the outer lens side, the outer circumferential portion of the light guide is positioned on the inner circumferential side relative to a bonded portion of the outer circumferential portion of the outer lens, the bonded portion being bonded to the housing.

6 . The emblem according to claim 1 , wherein:

an outer circumferential surface of the outer circumferential portion of the light guide is an inclined surface inclined toward an outer circumferential side on progression toward the outer lens side, and

the light rays from the light source are guided to the inclined surface of the light guide and are reflected from the inclined surface to the outer circumferential portion of the outer lens.
