As shown in FIG. 2, the first light source unit 11 includes a first lens 21, a first light source 31, a shade 40, and a mounting board 6. The shade 40 blocks part of the light emitted from the first light source 31. The first light source unit 11 emits light so that the area where the driver of the oncoming vehicle is present is not irradiated with light.
The second light source unit 12 has a second lens 22, a second light source 32, and a mounting board 6. The second light source unit 12 does not have a shade 40 and can irradiate all of the light emitted from the second light source 32 to the outside.
The third light source unit 13, which is not shown in FIG. 2, has a third lens 23, a third light source 33, a shade 40, and a mounting board 6, like the first light source unit 11. Like the first light source unit, the third light source unit emits light so that the area where the driver of the oncoming vehicle is present is not irradiated with light.

In this embodiment, the first lens 21, the second lens 22, and the third lens 23 are composed of convex lenses. Further, the first light source 31, the second light source 32, and the third light source 33 are each composed of an LED or the like, and are provided on the mounting board 6. Note that the first light source unit 11, the second light source unit 12, and the third light source unit 13 may include members other than the above-mentioned members. For example, a reflector, a lens holder, etc. may be provided.

The first light source unit 11 and the third light source unit 13 are capable of emitting a low beam light distribution pattern. As shown in FIG. 1, in this embodiment, the first light source unit 11 is arranged below the third light source unit 13 (D direction), and the first light source unit 11 is arranged in the vertical direction (UD direction) together with the third light source unit 13. ) is formed to extend into a first light emitting region Lo.
The second light source unit 12 emits a high beam light distribution pattern together with the first light source unit 11. In this embodiment, the second light source unit 12 is arranged on the left side (L direction) of the first light source unit 11, and the second light source unit 12 has a second light emitting area extending in the left-right direction (LR direction) together with the first light source unit 11. Forms Hi.
That is, the entire light source unit 10 is arranged in an L-shape when viewed from the front of the vehicle, and the first light emitting region Lo and the second light emitting region Hi overlap in the portion where the first light source unit 11 is located.

Next, the vehicle headlamp 1 in this embodiment when emitting a low beam light distribution pattern and when emitting a high beam light distribution pattern will be described using FIGS. 3 and 4. FIG. 3 is an external view of the vehicle headlamp 1 according to the present embodiment when the low beam light distribution pattern is irradiated. Further, FIG. 4 is an external view of the vehicle headlamp 1 according to the present embodiment when emitting a high beam light distribution pattern. In FIGS. 3 and 4, the parts that appear to shine are expressed with diagonal lines.

As shown in FIG. 3, when the vehicle headlamp 1 emits a low beam light distribution pattern, the first light emitting region Lo composed of the first light source unit 11 and the third light source unit 13 emits light. In this embodiment, the first light emitting region extends in the vertical direction (UD direction).
On the other hand, as shown in FIG. 4, when the vehicle headlamp 1 emits a high beam light distribution pattern, the second light emitting region Hi composed of the second light source unit 12 and the third light source unit 13 emits light. In this embodiment, the second light emitting region extends in the left-right direction (LR direction).

Comparing FIG. 3 and FIG. 4, the light emitting region extends in different directions when the low beam light distribution pattern is irradiated and when the high beam light distribution pattern is irradiated. When viewing the vehicle headlight 1 from the front, the vehicle headlight 1 appears to be a vertically elongated lamp when emitting a low beam light distribution pattern, but when emitting a high beam light distribution pattern, the vehicle headlamp 1 appears to be a horizontally elongated lamp. Looks like a lamp. In other words, by arranging the light source unit 10 as in this embodiment, the shape of the light-emitting area that appears to glow changes as the irradiation light distribution pattern changes, thereby creating a vehicle headlight with a novel appearance that has never been seen before. can be provided.

(Modified example)
FIG. 5 is a diagram showing a modification of the vehicle headlamp 1 according to the present disclosure. In the embodiment described above, an example in which the light source unit 10 is arranged in an L-shape has been described, but the vehicle headlamp 1 according to the present disclosure is not limited to this. For example, the light source units may be arranged in a cross shape as shown in FIG.

In the embodiment shown in FIG. 5, a vehicle headlamp 1000 includes a housing 200 and a plurality of light source units 100. The light source unit 100 includes a first light source unit 101, a second light source unit 102, a third light source unit 103, a fourth light source unit 104, and a fifth light source unit 105. The first light source unit 101, the fifth light source unit 105, and the third light source unit 103 constitute a first light emitting region Lo extending in the vertical direction (UD direction). The fourth light source unit 104, the fifth light source unit 105, and the second light source unit 102 constitute a second light emitting region Hi extending in the left-right direction (LR direction).
In the embodiment described above, the first light emitting region Lo and the second light emitting region Hi overlap in the portion where the fifth light source unit 105 is located.

By arranging the light source units in a cross shape as shown in FIG. 5, it is also possible to provide the vehicle headlamp 1 with an innovative appearance.

Although FIG. 1 describes an example in which the light source units 10 are arranged in an L-shape, and FIG. 5 describes an example in which the light source units 100 are arranged in a cross-shape, the present invention is not limited to these. The light source units may be arranged in an X-shape. The light source unit may be arranged so that the shapes of the light-emitting regions that appear to shine are different when the low beam light distribution pattern is irradiated and when the high beam light distribution pattern is irradiated. However, it is preferable that the direction in which the first light-emitting region Lo extends and the direction in which the second light-emitting region Hi extends intersect with each other at an angle of 30 degrees or more so that the change in the shape of the light-emitting region can be easily seen even from a distance. Further, due to size constraints of the vehicle headlamp 1, it is preferable that the first light emitting region Lo and the second light emitting region Hi share a part with each other.

In addition, in the vehicle headlamp 1 according to the present disclosure, the light source unit 10 divided into a plurality of parts may be configured to be able to be turned on and off individually. This makes it possible to provide a vehicle headlamp 1 with a simple configuration and an innovative appearance.

Further, the light emitting region of the vehicle headlamp 1 according to the present disclosure may be composed of only the first light emitting region Lo and the second light emitting region Hi. As a result, it is possible to make the appearance different when the low beam light distribution pattern is irradiated and when the high beam light distribution pattern is irradiated with a simple configuration, so it is possible to provide the vehicle headlamp 1 with an innovative appearance.

Although the embodiments of the present disclosure have been described above, it goes without saying that the technical scope of the present disclosure should not be interpreted in a limited manner by the description of the embodiments. This embodiment is merely an example, and those skilled in the art will understand that various modifications can be made within the scope of the invention described in the claims. The technical scope of the present disclosure should be determined based on the scope of the invention described in the claims and the scope of equivalents thereof.
