Description

車両用の前照灯Vehicle headlamp
　本発明は、車両用の前照灯に関する。 The present invention relates to a vehicle headlamp.
　従来、車両用の前照灯の技術は公知である（例えば、特許文献１）。
　特許文献１に記載の前照灯は、車両の前端に設置される。特許文献１に記載の前照灯は、二つの光源１６・１７と反射板２・３を上下に並列に配置するので、上下方向の厚みが大きくなる。これにより、前照灯を車両に設置するためには、上下方向に大きな厚みを有する設置スペースを確保しなければならず、設置の自由度が制限されるおそれがあった。
　また、特許文献１に記載の前照灯は、光源１６・１７毎に基板８・９が設けられるため、光源１６・１７の数と同数の基板８・９が必要になる。これにより、装置の製造コストが増大し、装置構成が複雑化するおそれがあった。 Conventionally, the technique of the headlamp for vehicles is well-known (for example, patent document 1).
The headlamp described in Patent Document 1 is installed at the front end of a vehicle. The headlamp described in Patent Document 1 has two light sources 16 and 17 and reflectors 2 and 3 arranged in parallel in the vertical direction, so that the thickness in the vertical direction increases. Thereby, in order to install the headlamp in the vehicle, it is necessary to secure an installation space having a large thickness in the vertical direction, which may limit the degree of freedom of installation.
Moreover, since the headlamp described in Patent Document 1 is provided with the substrates 8 and 9 for each of the light sources 16 and 17, the same number of substrates 8 and 9 as the number of the light sources 16 and 17 is required. As a result, the manufacturing cost of the apparatus increases, and the apparatus configuration may be complicated.

　以下では、前照灯１００・２００について説明する。 Hereinafter, the headlamps 100 and 200 will be described.
　図１～図３に示すように、前照灯１００・２００は、田植機１の前部における上面部１７に設置される。田植機１の前部における上面部１７は、後方に向かうに従って、上方に傾斜する形状を有している。 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.
　前照灯１００・２００は、ボンネット１８の側方に設置される。前照灯１００は、ボンネット１８の左側に設置され、前照灯２００は、ボンネット１８の右側に設置される。
　前照灯１００・２００は、左右対称な構成を有するので、左側の前照灯１００について説明し、右側の前照灯２００の説明は省略する。 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.
　図４～図７に示すように、前照灯１００は、ハウジング１１０と、レンズ１２０と、インナー部材１３０と、ベース基板１４０と、反射板１５０と、光源１６０と、防止機構１７０と、を備える。 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 reflector 150, a light source 160, and a prevention mechanism 170. .
　ハウジング１１０にはレンズ１２０が取り付けられている。レンズ１２０とハウジング１１０で囲まれた空間内には、インナー部材１３０が収容されている。インナー部材１３０の隔壁１３１と、ハウジング１１０の側壁１１１と、の間にはベース基板１４０が配置されている（図７参照）。 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).
　図１０に示すように、インナー部材１３０には、反射板１５０が形成されている。ベース基板１４０には、光源１６０が設けられている。光源１６０から照射された照射光は、反射板１５０で反射されて、田植機１の前方へ放出される。光源１６０は、例えば、ＬＥＤである。 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.
　光源１６０は、複数設けられている。本実施形態では、二つの光源１６０が設けられている。
　反射板１５０も複数設けられている。本実施形態では、二つの反射板１５０が設けられている。
　それぞれの光源１６０に対して、反射板１５０がそれぞれ設けられており、光源１６０と反射板１５０とが、一対一で対応している。
　このように、それぞれの光源１６０に対して、反射板１５０がそれぞれ設けられることで、各光源１６０から照射された照射光が、各光源１６０に対応する反射板１５０でそれぞれ反射される。 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.
　以下では、反射板１５０について説明する。 Hereinafter, the reflector 150 will be described.
　図５に示すように、複数の反射板１５０は、単一の部材（インナー部材１３０）に形成されており、これにより、一体的に構成されている。 As shown in FIG. 5, the plurality of reflecting plates 150 are formed as a single member (inner member 130), and are thus integrally formed.
　前照灯１００が田植機１に設置された状態のとき、複数の反射板１５０が、前後方向に並んだ状態にて、上下方向の位置を互いに異ならせた位置に配置されている。
　上記した「複数の反射板１５０が、前後方向に並んだ状態」とは、複数の反射板１５０の前後方向の位置が互いに異なっており、かつ、田植機１を前方から見て複数の反射板１５０を確認したときに、複数の反射板１５０の全部又は一部が互いに重なって見える状態である。本実施形態では、複数の反射板１５０の一部が互いに重なって見える状態になっている（図８の上段図の領域α参照）。
　上記した「上下方向の位置を互いに異ならせた位置」とは、上記した「複数の反射板１５０が、前後方向に並んだ状態」から、複数の反射板１５０の位置を上下方向に互いにずらすことで、複数の反射板１５０に対して互いに高低差Ｄ２を設けて、複数の反射板１５０のうち、後方に存在するもの程、高い位置に配置した状態である（図８の中段図、及び下段図参照）。
　これにより、本実施形態では、田植機１に前照灯１００が設置されている状態で、田植機１を上方から見て複数の反射板１５０を確認したとき、複数の反射板１５０が前後方向に互いに間隔Ｄ１を空けて並んでいると共に（図９参照）、田植機１を前方から見て複数の反射板１５０を確認したとき、複数の反射板１５０が上下方向に互いに高低差Ｄ２を設けて配置される（図８の下段図参照）。
　これにより、複数の反射板１５０が、上下方向及び左右方向に並置されることを回避している。 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 in a state where 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.
　複数の反射板１５０においては、後方に存在するもの程、高い位置に配置される（図８の下段図参照）。すなわち、前後方向に隣り合う反射板１５０においては、前方に存在するものの上端よりも、後方に存在するものの上端の方が高い位置に配置される。
　また、田植機１に前照灯１００が設置されている状態で、田植機１を前方から見て複数の反射板１５０を確認したときに、複数の反射板１５０が互いに重ならない程度に、複数の反射板１５０に対して互いに高低差Ｄ２が設けられている（図８の下段図参照）。 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).
　複数の反射板１５０の前方は、レンズ１２０で覆われている（図４及び図６参照）。 The front of the plurality of reflectors 150 is covered with a lens 120 (see FIGS. 4 and 6).
　前照灯１００は、複数の反射板１５０の並びに沿うような形状に形成される。これにより、前照灯１００は、田植機１に設置された状態のとき、前後方向に長手の形状を有しており（図２参照）、さらに、後方に向かうに従って、上方に傾斜している（図１参照）。
　前照灯１００は、複数の反射板１５０の並びに沿うような形状に形成されることで、上下方向の厚みを抑えることができ、かつ、左右方向の寸法を抑えることができる。これは、複数の反射板１５０が、上下方向及び左右方向に並置されないように配置されているからである。 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.
　以下では、光源１６０について説明する。 Hereinafter, the light source 160 will be described.
　図５及び図１０に示すように、複数の光源１６０は、単一のベース基板１４０に設けられる。
　ベース基板１４０は、複数の反射板１５０の並びに沿うように設けられる（図１０参照）。また、ベース基盤１４０は、複数の反射板１５０対してそれらの並ぶ方向と垂直な方向に間隔を空けて設けられ、複数の反射板１５０の列に対して平行（略平行も含む）に設けられる（図１０参照）。ベース基板１４０については、複数の反射板１５０の列と対向する側の盤面１４１には、複数の光源１６０が設けられる（図５及び図１０参照）。ベース基板１４０の盤面１４１は、略鉛直に配置されている。複数の光源１６０は、複数の反射板１５０の並びに沿うように設けられる（図１０参照）。また、複数の光源１６０は、複数の反射板１５０に対してそれらの並ぶ方向と垂直な方向に間隔を空けて設けられ、複数の反射板１５０の列に対して並列になるように並べられる（図１０参照）。 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).
　前照灯１００が田植機１に設置された状態で、田植機１を前方から見て複数の光源１６０を確認したとき、複数の光源１６０は、上下方向に並ぶように配置されている。 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.
　図１０に示すように、前照灯１００が田植機１に設置された状態において、各光源１６０の側方には、各光源１６０に対応する反射板１５０がそれぞれ配置されている。 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 arranged on the side of each light source 160.
　複数の光源１６０と、複数の反射板１５０との間には、隔壁１３１が配置されている。
　隔壁１３１に対しては、各光源１６０と、各光源１６０に対応する反射板１５０と、の間に存在する箇所に、孔１３２がそれぞれ形成されている。これにより、各光源１６０は、各孔１３２を介して、各光源１６０に対応する反射板１５０とそれぞれ対向配置される。各光源１６０から照射された照射光は、各孔１３２を通じて、各光源１６０に対応する反射板１５０へそれぞれ到達する。 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.
　前照灯１００が田植機１に設置された状態において、複数の光源１６０がその前方を隔壁１３１で覆われた状態になっている。これにより、田植機１を前方から見たとき、複数の光源１６０を視認できない状態になっている。これにより、田植機１を前方（及び、ななめ前方）から見たときに、光源１６０が直接に見えて眩惑されることが防止される。また、前照灯１００が田植機１に設置された状態において、複数の光源１６０がその前方を隔壁１３１で覆われることで、複数の光源１６０から前方へ照射される照射光が隔壁１３１で遮られ、直射光（後述）が遮られる。 In a state where the headlamp 100 is installed in the rice transplanter 1, a 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.
　図１０に示すように、前照灯１００が田植機１に設置された状態において、各光源１６０から照射された照射光が、各光源１６０に対応する反射板１５０でそれぞれ反射されて、田植機１の前方へそれぞれ放出される。
　詳細には、各光源１６０から照射された照射光の内で側方へ進行したものが（図１０の矢印Ａ１参照）、各光源１６０に対応する反射板１５０でそれぞれ反射されると共に、進行方向を略９０°変更されて、田植機１の前方へそれぞれ放出される（図１０の矢印Ａ２参照）。
　従って、各光源１６０から照射された照射光につては、各光源１６０に対応する反射板１５０に向かうときの進行方向Ａ１と、各反射板１５０から放出されるときの進行方向Ａ２と、が互いに異なっている。 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.
