  Hereinafter, the headlamps 100 and 200 will be described.

  As shown in FIGS. 1 to 3, the headlamps 100 and 200 are installed on the upper surface portion 17 in the front portion of the rice transplanter 1. The upper surface part 17 in the front part of the rice transplanter 1 has a shape which inclines upward as it goes back.

The headlamps 100 and 200 are installed on the side of the bonnet 18. The headlamp 100 is installed on the left side of the hood 18, and the headlamp 200 is installed on the right side of the hood 18.
Since the headlamps 100 and 200 have a symmetrical configuration, only the left headlamp 100 will be described, and the description of the right headlamp 200 will be omitted.

  As shown in FIGS. 4 to 7, the headlamp 100 includes a housing 110, a lens 120, an inner member 130, a base substrate 140, a reflecting plate 150, a light source 160, and a prevention mechanism 170. .

  A lens 120 is attached to the housing 110. An inner member 130 is accommodated in the space surrounded by the lens 120 and the housing 110. A base substrate 140 is disposed between the partition wall 131 of the inner member 130 and the side wall 111 of the housing 110 (see FIG. 7).

  As shown in FIG. 10, a reflective plate 150 is formed on the inner member 130. A light source 160 is provided on the base substrate 140. Irradiation light emitted from the light source 160 is reflected by the reflector 150 and emitted to the front of the rice transplanter 1. The light source 160 is, for example, an LED.

A plurality of light sources 160 are provided. In the present embodiment, two light sources 160 are provided.
A plurality of reflectors 150 are also provided. In the present embodiment, two reflecting plates 150 are provided.
A reflecting plate 150 is provided for each light source 160, and the light source 160 and the reflecting plate 150 correspond one to one.
Thus, by providing the reflecting plate 150 for each light source 160, the irradiation light emitted from each light source 160 is reflected by the reflecting plate 150 corresponding to each light source 160, respectively.

  Hereinafter, the reflector 150 will be described.

  As shown in FIG. 5, the plurality of reflectors 150 are formed as a single member (inner member 130), and are thus integrally formed.

When the headlamp 100 is installed in the rice transplanter 1, the plurality of reflectors 150 are arranged at positions that are different from each other in the vertical direction from the state in which they are arranged in the front-rear direction.
The above-mentioned “state where the plurality of reflecting plates 150 are arranged in the front-rear direction” is different from each other in the position of the plurality of reflecting plates 150 in the front-rear direction, and a plurality of reflecting plates when the rice transplanter 1 is viewed from the front. When 150 is confirmed, all or some of the plurality of reflectors 150 appear to overlap each other. In the present embodiment, a part of the plurality of reflectors 150 is seen to overlap each other (see region α in the upper diagram of FIG. 8).
The above-mentioned “positions in which the positions in the vertical direction are different from each other” means that the positions of the plurality of reflective plates 150 are shifted in the vertical direction from the “state in which the plurality of reflective plates 150 are arranged in the front-rear direction”. Thus, the height difference D2 is provided to the plurality of reflectors 150, and the more the reflectors 150 located behind, the higher the positions are arranged (the middle and lower stages of FIG. 8). (See figure).
Thereby, in this embodiment, when the headlamp 100 is installed in the rice transplanter 1 and the plurality of reflectors 150 are confirmed when the rice transplanter 1 is viewed from above, the plurality of reflectors 150 are in the front-rear direction. Are arranged with a gap D1 therebetween (see FIG. 9), and when the plurality of reflectors 150 are confirmed when the rice transplanter 1 is viewed from the front, the plurality of reflectors 150 are provided with a height difference D2 in the vertical direction. (See the lower diagram in FIG. 8).
Thereby, it is avoided that the several reflecting plate 150 is juxtaposed in the up-down direction and the left-right direction.

In the plurality of reflectors 150, the rearward ones are arranged at higher positions (see the lower diagram in FIG. 8). In other words, in the reflectors 150 adjacent in the front-rear direction, the upper end of the one existing in the rear is arranged at a higher position than the upper end of the one existing in the front.
In addition, when the headlamp 100 is installed on the rice transplanter 1 and the plurality of reflectors 150 are confirmed when the rice transplanter 1 is viewed from the front, the plurality of reflectors 150 are not overlapped with each other. A height difference D2 is provided with respect to the reflector 150 (see the lower part of FIG. 8).

  The front of the plurality of reflectors 150 is covered with a lens 120 (see FIGS. 4 and 6).

The headlamp 100 is formed in a shape along which a plurality of reflectors 150 are arranged. Thereby, when the headlamp 100 is installed in the rice transplanter 1, it has a longitudinal shape in the front-rear direction (see FIG. 2), and further inclines upward toward the rear. (See FIG. 1).
Since the headlamp 100 is formed in a shape along the arrangement of the plurality of reflectors 150, the thickness in the vertical direction can be suppressed, and the size in the horizontal direction can be suppressed. This is because the plurality of reflecting plates 150 are arranged so as not to be juxtaposed in the vertical direction and the horizontal direction.

  Hereinafter, the light source 160 will be described.

As shown in FIGS. 5 and 10, the plurality of light sources 160 are provided on a single base substrate 140.
The base substrate 140 is provided along the arrangement of the plurality of reflecting plates 150 (see FIG. 10). The base substrate 140 is provided with a space in the direction perpendicular to the direction in which the plurality of reflectors 150 are arranged, and is provided in parallel (including substantially parallel) to the row of the plurality of reflectors 150. (See FIG. 10). As for the base substrate 140, a plurality of light sources 160 are provided on the surface 141 facing the row of the plurality of reflecting plates 150 (see FIGS. 5 and 10). The board surface 141 of the base substrate 140 is disposed substantially vertically. The plurality of light sources 160 are provided along the plurality of reflectors 150 (see FIG. 10). In addition, the plurality of light sources 160 are provided at intervals in a direction perpendicular to the direction in which the plurality of reflection plates 150 are arranged, and are arranged in parallel to the row of the plurality of reflection plates 150 ( (See FIG. 10).

  When the headlamps 100 are installed in the rice transplanter 1 and the plurality of light sources 160 are confirmed when the rice transplanter 1 is viewed from the front, the plurality of light sources 160 are arranged in the vertical direction.

  As shown in FIG. 10, in a state where the headlamp 100 is installed in the rice transplanter 1, a reflector 150 corresponding to each light source 160 is disposed on the side of each light source 160.

A partition wall 131 is disposed between the plurality of light sources 160 and the plurality of reflection plates 150.
For the partition wall 131, holes 132 are respectively formed at locations between the light sources 160 and the reflecting plate 150 corresponding to the light sources 160. Accordingly, each light source 160 is disposed to face the reflecting plate 150 corresponding to each light source 160 through each hole 132. Irradiation light emitted from each light source 160 reaches the reflecting plate 150 corresponding to each light source 160 through each hole 132.

  In a state where the headlamp 100 is installed in the rice transplanter 1, the plurality of light sources 160 are covered with a partition wall 131 in front thereof. Thereby, when the rice transplanter 1 is viewed from the front, the plurality of light sources 160 cannot be visually recognized. Thereby, when the rice transplanter 1 is viewed from the front (and the tanned front), the light source 160 is prevented from being directly seen and dazzled. Further, in the state where the headlamp 100 is installed in the rice transplanter 1, the plurality of light sources 160 are covered with the partition wall 131 in front of the plurality of light sources 160, so that the irradiation light irradiated forward from the plurality of light sources 160 is blocked by the partition wall 131. And direct light (described later) is blocked.

As shown in FIG. 10, in the state where the headlamp 100 is installed in the rice transplanter 1, the irradiation light emitted from each light source 160 is reflected by the reflecting plate 150 corresponding to each light source 160, and the rice transplanter 1 is discharged to the front of each.
More specifically, the irradiation light emitted from each light source 160 that has traveled to the side (see arrow A1 in FIG. 10) is reflected by the reflecting plate 150 corresponding to each light source 160 and the traveling direction. Is changed by approximately 90 ° and discharged forward of the rice transplanter 1 (see arrow A2 in FIG. 10).
Therefore, for the irradiation light emitted from each light source 160, the traveling direction A1 when traveling toward the reflecting plate 150 corresponding to each light source 160 and the traveling direction A2 when emitted from each reflecting plate 150 are mutually different. Is different.

  The plurality of reflectors 150 are arranged at higher positions as they are present in the rear, so that the rear reflector 150 does not interfere with the front reflector 150 and emits irradiation light in front of the rice transplanter 1. (See FIG. 10). As a result, from the headlamp 100, the irradiation light is emitted forward of the rice transplanter 1 in a multistage manner.

  In the present embodiment, the base substrate 140 and the light source 160 are provided on the side of the row of the plurality of reflecting plates 150 (see FIG. 10), but the present invention is not limited to this, and may be provided above or below. The base substrate 140 may be provided so as to be aligned with the plurality of reflecting plates 150.

  Hereinafter, the prevention mechanism 170 will be described.

(3) A plurality of light sources 160 are arranged inside the enclosed space 133 and a plurality of reflectors 150 are arranged outside the enclosed space 133. Then, the holes 132 are respectively formed corresponding to the respective light sources 160, and (5) the irradiation light emitted from the respective light sources 160 is emitted to the outside of the closed space 133 through the holes 132 corresponding to the respective light sources 160. Each of the light guides 160 is guided to the reflecting plate 150 and reflected by each of the reflections 150 and then emitted forward of the rice transplanter 1.
In this manner, each hole 132 of the partition wall 131 guides the irradiation light emitted from each light source 160 to the reflecting plate 150 corresponding to each light source 160. Thereby, the irradiation light irradiated from each light source 160 is reflected by the reflecting plate 150 corresponding to each light source 160 and then emitted forward of the rice transplanter 1. Thereby, generation | occurrence | production of the said direct light is prevented.
In the present embodiment, the shielding member for forming the closed space 133 includes a partition wall 131 and a side wall 111. Therefore, the closed space 133 is formed between the partition wall 131 and the side wall 111.

  Note that a partition wall 131 for blocking the direct light may be provided in the base substrate 140. Thereby, since the partition wall 131 is configured separately from the reflector 150, the partition wall 131 can be installed without being restricted by the positional relationship with respect to the reflector 150, and the degree of freedom of installation is improved.

Further, as shown in FIGS. 5 and 10, a light source 180 of a lamp having a role different from that of the headlamp 100 may be provided on the base substrate 140.
In the present embodiment, the lamp having a role different from that of the headlamp 100 is a decorative lamp. The light source 180 is disposed behind the light source 160. In the partition wall 131, a hole 134 is formed on the side of the light source 180. Irradiation light emitted from the light source 180 of the decorative lamp is emitted through the hole 134 (see arrow A3 in FIG. 10).
The lamp having a role different from that of the headlamp 100 is not limited to a decorative lamp, and may be a vehicle width lamp or a direction indicator lamp.

As described above, the headlamp 100 is
