Abstract
A moving-body lighting device includes: a first light source; a second light source that is disposed forward of the first light source and emits light forward; a reflector in a shape of a segment of a spheroid, and that reflects the light emitted by the first light source; a projection lens that receives the light emitted by the first light source and reflected by the reflector; and a shade disposed between the second light source and the projection lens, proximate a second focal point. The projection lens includes a first lens region that receives the light emitted by the first light source and reflected by the reflector, and a second lens region that receives the light emitted by the second light source. The major axis of the spheroid is oblique to a horizontal axis.

A moving-body lighting device configured to be used in a moving body, the moving-body lighting device comprising:
- a first light source that emits light;
- a second light source that is disposed forward of the first light source and emits light forward;
- a reflector in a shape of a segment of a spheroid having a first focal point proximate the first light source and a second focal point, and that reflects the light emitted by the first light source;
- a projection lens that is disposed forward of the second light source and receives the light emitted by the first light source and reflected by the reflector;
- and
- a shield disposed between the second light source and the projection lens, proximate the second focal point,
- wherein:
- the shield includes an edge region including a step, the edge region blocking a portion of the light reflected by the reflector and transmitting a remaining portion of the light to the projection lens,
- the projection lens includes a first lens region that receives the light emitted by the first light source and reflected by the reflector, and a second lens region that receives the light emitted by the second light source, and
- a major axis of the spheroid is oblique to a horizontal axis in an installation position of the moving-body lighting device in the moving body.
A moving-body lighting device configured to be used in a moving body, the moving-body lighting device comprising:

- the shield:
- is disposed proximate the second focal point;
- and
- includes an edge region including a step, the edge region blocking a portion of the light reflected by the reflector and transmitting a remaining portion of the light to the projection lens,
- the projection lens includes a first lens region that receives the light emitted by the first light source and reflected by the reflector, and a second lens region that receives the light emitted by the second light source, and
- a major axis of the spheroid intersects a horizontal axis in an installation position of the moving-body lighting device the moving body.
A moving body, comprising:
- a headlight;
- and
- a moving-body light installed in the headlight, the moving-body light comprising:
- a first light source that emits light;
- a second light source that is disposed forward of the first light source and emits light forward;
- a reflector in a shape of a segment of a spheroid having a first focal point proximate the first light source and a second focal point, and that reflects the light emitted by the first light source;
- a projection lens that is disposed forward of the second light source and receives the light emitted by the first light source and reflected by the reflector;
- and
- a shield disposed between the second light source and the projection lens, proximate the second focal point,
- wherein:
- the shield includes an edge region including a step, the edge region blocking a portion of the light reflected by the reflector and transmitting a remaining portion of the light to the projection lens,
- the projection lens includes a first lens region that receives the light emitted by the first light source and reflected by the reflector, and a second lens region that receives the light emitted by the second light source, and
- a major axis of the spheroid is oblique to a horizontal axis.
