## Abstract

A luminescent emblem includes a housing including a reflection surface, a cover including at least one transmissive part through which visible light transmits, and a substrate on which a light source is mounted. The housing includes a bottom wall portion, an outer peripheral wall portion, and a connection wall portion. The bottom wall portion includes a projection projecting toward the cover. The projection includes a flat portion and an inner peripheral wall portion surrounding the flat portion. The at least one transmissive part includes a transmissive part disposed on a peripheral portion of the cover. The reflection surface includes a primary reflection surface that reflects visible light toward a peripheral side of the housing and a secondary reflection surface that receives and reflects light toward the transmissive part, disposed on the peripheral portion of the cover.

## Claims

### Claim 1

A luminescent emblem, comprising:
a housing including an opening that is open outward from a vehicle and a reflection surface that reflects visible light;
a cover closing the opening and including at least one transmissive part that is transmissive to the visible light; and
a substrate accommodated between the housing and the cover, wherein a light source is mounted on the substrate to emit the visible light toward the reflection surface, wherein
the visible light reflected from the housing toward the cover is transmitted through the at least one transmissive part to illuminate the cover,
the housing includes a bottom wall portion, an outer peripheral wall portion defining the opening, and a connection wall portion connecting the bottom wall portion and the outer peripheral wall portion,
the bottom wall portion includes a projection projecting toward the cover,
the projection includes a flat portion on which the substrate is mounted and an inner peripheral wall portion surrounding the flat portion,
the at least one transmissive part includes a transmissive part disposed on a peripheral portion of the cover, and
the reflection surface includes
a primary reflection surface disposed on at least one of a peripheral edge of the flat portion and the inner peripheral wall portion and inclined with respect to an optical axis of the light source to reflect the visible light toward a peripheral side of the housing, and
a secondary reflection surface disposed on the connection wall portion and inclined with respect to the optical axis to receive and reflect the visible light toward the transmissive part disposed on the peripheral portion of the cover.

### Claim 2 (depends on 1)

The luminescent emblem according to claim 1, wherein
the primary reflection surface includes a first inclined surface and a second inclined surface differing from each other in an inclination angle inclined with respect to the optical axis,
the first inclined surface is disposed on the peripheral edge of the flat portion and is opposed to the light source in an axial direction in which the optical axis extends,
the first inclined surface reflects the visible light emitted from the light source along the optical axis toward the secondary reflection surface, and
the second inclined surface is disposed on the inner peripheral wall portion and reflects the visible light emitted from the light source toward the secondary reflection surface at an emission angle inclined with respect to the optical axis by a first angle.

### Claim 3 (depends on 2)

The luminescent emblem according to claim 2, wherein
a peripheral side of the housing is referred to as a peripheral side,
the primary reflection surface includes a third inclined surface differing from the first inclined surface and the second inclined surface in an inclination angle from the optical axis, and
the third inclined surface is disposed on the inner peripheral wall portion toward the peripheral side from the second inclined surface and reflects the visible light emitted from the light source toward the secondary reflection surface at an emission angle inclined with respect to the optical axis by a second angle that is greater than the first angle.

### Claim 4 (depends on 1)

The luminescent emblem according to claim 1, wherein
a peripheral side of the housing is referred to as a peripheral side,
the substrate includes an opposing part opposed to the flat portion in an axial direction in which the optical axis extends and an extension extending from the opposing part toward the peripheral side from the flat portion,
the at least one transmissive part includes a transmissive part disposed in a center of the cover,
the light source is a first light source, the first light source being mounted on the extension, and
a second light source is mounted on the opposing part and directly emits the visible light toward the transmissive part, which is disposed in the center of the cover.
