本発明は、車両用灯具に関する。 The present invention relates to a vehicle lamp.

車両用灯具は、他車両や歩行者に対して自車両の存在や状態を認識させる自車表示機能を有する（例えば特許文献１参照）。 Vehicle lighting devices have a vehicle display function that makes other vehicles and pedestrians aware of the presence and status of the vehicle (see, for example, Patent Document 1).

特開２００６－２１６４５５号公報JP 2006-216455 A

車両運転の安全性を向上させたいという要求は常にある。この要求に応えるために、車両用灯具の自車表示機能をより高めて、他車両や歩行者に注意喚起することが望まれる。一方で、灯具ケースの形状によっては発光部を視認可能な範囲が制限され、自車表示機能を高めることが困難な場合がある。 There is a constant demand for improved vehicle driving safety. To meet this demand, it is desirable to further improve the vehicle's own vehicle indication function in vehicle lighting to alert other vehicles and pedestrians. However, depending on the shape of the lighting case, the range in which the light-emitting part can be seen may be limited, making it difficult to improve the vehicle's indication function.

本発明はこうした状況に鑑みてなされたものであり、その目的の１つは、車両用灯具の自車表示機能の向上を図る技術を提供することにある。 The present invention was made in light of these circumstances, and one of its objectives is to provide technology that improves the vehicle display function of vehicle lighting fixtures.

上記課題を解決するために、本発明のある態様は車両用灯具である。この車両用灯具は、平面状の透光カバーを有するケースと、ケースに収容され、透光カバーに向け光を照射する第１発光部および第２発光部とを備える。第１発光部は、車幅方向に延びる第１長尺部と、第１長尺部の車幅方向外側の端部から車幅方向と交わる方向に突出し、且つ第１長尺部の幅より太い幅を有する第１突出部とを有する。第２発光部は、車幅方向に延びる第２長尺部と、第２長尺部の車幅方向外側の端部から車幅方向と交わる方向に突出し、且つ第２長尺部の幅より太い幅を有する第２突出部とを有する。第１突出部の先端は、第１長尺部よりも鉛直方向の第１側に位置し、第２突出部の先端は、第２長尺部よりも第１側に位置する。第２発光部は、第１長尺部よりも第１側で且つ第１突出部よりも車幅方向内側に配置される。 In order to solve the above problem, one aspect of the present invention is a vehicle lamp. This vehicle lamp includes a case having a planar translucent cover, and a first light-emitting unit and a second light-emitting unit that are housed in the case and irradiate light toward the translucent cover. The first light-emitting unit has a first long portion extending in the vehicle width direction, and a first protruding portion that protrudes from an end portion of the first long portion on the outer side of the vehicle width direction in a direction intersecting with the vehicle width direction and has a width greater than that of the first long portion. The second light-emitting unit has a second long portion extending in the vehicle width direction, and a second protruding portion that protrudes from an end portion of the second long portion on the outer side of the vehicle width direction in a direction intersecting with the vehicle width direction and has a width greater than that of the second long portion. The tip of the first protruding portion is located on the first side in the vertical direction from the first long portion, and the tip of the second protruding portion is located on the first side from the second long portion. The second light emitting portion is disposed on the first side of the first elongated portion and on the inside in the vehicle width direction of the first protruding portion.

なお、以上の構成要素の任意の組合せ、本発明の表現を方法、装置、システム等の間で変換したものもまた、本発明の態様として有効である。 In addition, any combination of the above components, and any conversion of the present invention between methods, devices, systems, etc., are also valid aspects of the present invention.

本発明によれば、車両用灯具の自車表示機能の向上を図ることができる。 The present invention can improve the vehicle display function of vehicle lighting.

以下、本発明を好適な実施の形態をもとに図面を参照しながら説明する。実施の形態は、発明を限定するものではなく例示であって、実施の形態に記述されるすべての特徴やその組み合わせは、必ずしも発明の本質的なものであるとは限らない。各図面に示される同一または同等の構成要素、部材、処理には、同一の符号を付するものとし、適宜重複した説明は省略する。また、各図に示す各部の縮尺や形状は、説明を容易にするために便宜的に設定されており、特に言及がない限り限定的に解釈されるものではない。また、本明細書または請求項中に「第１」、「第２」等の用語が用いられる場合には、特に言及がない限りこの用語はいかなる順序や重要度を表すものでもなく、ある構成と他の構成とを区別するためのものである。また、各図面において実施の形態を説明する上で重要ではない部材の一部は省略して表示する。 The present invention will be described below with reference to the drawings based on preferred embodiments. The embodiments are illustrative and do not limit the invention, and all features and combinations thereof described in the embodiments are not necessarily essential to the invention. The same or equivalent components, members, and processes shown in each drawing are given the same reference numerals, and duplicated descriptions are omitted as appropriate. The scale and shape of each part shown in each drawing are set for convenience to facilitate explanation, and are not to be interpreted as being limiting unless otherwise specified. In addition, when terms such as "first" and "second" are used in this specification or claims, unless otherwise specified, these terms do not indicate any order or importance, but are intended to distinguish one configuration from another. In addition, some of the members that are not important for explaining the embodiment are omitted in each drawing.

図１は、実施の形態に係る車両用灯具１の分解斜視図である。本実施の形態の車両用灯具１は、一例として車両の後部に配置されるリアランプである。図１において、「前」は灯具前方（車両後方）を、「後」は灯具後方（車両前方）を、「内」は車幅方向内側を、「外」は車幅方向外側を、「上」は鉛直方向上方を、「下」は鉛直方向下方をそれぞれ意味する。車両用灯具１は、ケース２と、エクステンション部材４と、第１灯具ユニット６と、第２灯具ユニット８とを備える。 Figure 1 is an exploded perspective view of a vehicle lamp 1 according to an embodiment. The vehicle lamp 1 of this embodiment is, as an example, a rear lamp disposed at the rear of a vehicle. In Figure 1, "front" means in front of the lamp (rear of the vehicle), "rear" means behind the lamp (front of the vehicle), "inside" means inside in the vehicle width direction, "outside" means outside in the vehicle width direction, "up" means above in the vertical direction, and "down" means below in the vertical direction. The vehicle lamp 1 comprises a case 2, an extension member 4, a first lamp unit 6, and a second lamp unit 8.

ケース２は、ランプボディ１０と、透光カバー１２とを有する。ランプボディ１０は、透光性を有しない直方体状の箱体である。ランプボディ１０は、灯具前方を向く一面に開口を有する。透光カバー１２は、ランプボディ１０の開口を覆う。透光カバー１２は、透光性を有する平面状の板体である。したがって、ケース２は、車幅方向を向く側面が不透明であり、ケース２に収容される第１灯具ユニット６および第２灯具ユニット８を車幅方向（真横）から直接視認することが困難である。 The case 2 has a lamp body 10 and a translucent cover 12. The lamp body 10 is a rectangular box that does not have translucency. The lamp body 10 has an opening on one side facing the front of the lamp. The translucent cover 12 covers the opening of the lamp body 10. The translucent cover 12 is a planar plate that has translucency. Therefore, the side of the case 2 facing the vehicle width direction is opaque, and it is difficult to directly see the first lamp unit 6 and the second lamp unit 8 housed in the case 2 from the vehicle width direction (directly to the side).

ランプボディ１０と透光カバー１２とで灯室が形成される。灯室には、エクステンション部材４と、第１灯具ユニット６と、第２灯具ユニット８とが収容される。エクステンション部材４は、車両用灯具１の内部構造を灯具外部から見えないようにするための目隠し用の部材である。エクステンション部材４は枠状であり、灯具前方側から見て枠内に第１灯具ユニット６および第２灯具ユニット８が配置される。 The lamp body 10 and the translucent cover 12 form a lamp chamber. The lamp chamber houses the extension member 4, the first lamp unit 6, and the second lamp unit 8. The extension member 4 is a concealing member that prevents the internal structure of the vehicle lamp 1 from being seen from outside the lamp. The extension member 4 is frame-shaped, and the first lamp unit 6 and the second lamp unit 8 are arranged within the frame when viewed from the front side of the lamp.

第１灯具ユニット６は、第１光源１４～第５光源２２と、ベース部材２４と、制御基板２６と、インナーレンズ２８と、光反射部材３０とを有する。第１光源１４～第５光源２２は、例えば配線基板に複数の発光素子が敷設された構造を有する。発光素子は、例えばＬＥＤ（発光ダイオード）である。なお、発光素子は、ＬＤ（レーザーダイオード）、有機または無機ＥＬ（エレクトロルミネセンス）等のＬＥＤ以外の半導体発光素子であってもよい。また、第１光源１４～第５光源２２は、白熱球、ハロゲンランプ、放電球等であってもよい。 The first lighting unit 6 has a first light source 14 to a fifth light source 22, a base member 24, a control board 26, an inner lens 28, and a light reflecting member 30. The first light source 14 to the fifth light source 22 have a structure in which a plurality of light emitting elements are arranged on a wiring board, for example. The light emitting elements are, for example, LEDs (light emitting diodes). Note that the light emitting elements may be semiconductor light emitting elements other than LEDs, such as LDs (laser diodes) or organic or inorganic ELs (electroluminescence). The first light source 14 to the fifth light source 22 may also be incandescent bulbs, halogen lamps, discharge bulbs, etc.

第１光源１４および第２光源１６は、車幅方向に長い矩形状であり、互いに車幅方向に並ぶ。第１光源１４は、第２光源１６よりも車幅方向内側に配置される。第３光源１８は、車幅方向外側に向かうほど鉛直方向上方に位置するよう湾曲する。第４光源２０は、車幅方向外側に向かうほど鉛直方向下方に位置するように湾曲する。第３光源１８および第４光源２０は鉛直方向に並び、且つ第２光源１６よりも車幅方向外側に配置される。第３光源１８は、第４光源２０よりも上方に配置される。第１光源１４～第４光源２０は、互いに集合して９０度回転したＹ字を形成している。 The first light source 14 and the second light source 16 are rectangular and elongated in the vehicle width direction, and are aligned with each other in the vehicle width direction. The first light source 14 is positioned further inward in the vehicle width direction than the second light source 16. The third light source 18 curves so that it is positioned vertically higher as it moves outward in the vehicle width direction. The fourth light source 20 curves so that it is positioned vertically lower as it moves outward in the vehicle width direction. The third light source 18 and the fourth light source 20 are aligned vertically, and are positioned further outward in the vehicle width direction than the second light source 16. The third light source 18 is positioned higher than the fourth light source 20. The first light source 14 to the fourth light source 20 are grouped together to form a Y shape rotated 90 degrees.

第５光源２２は、第１部分２２ａと、第２部分２２ｂと、第３部分２２ｃとを有する。第１部分２２ａは、車幅方向に延びる。第２部分２２ｂは、第１部分２２ａの車幅方向外側の端部から上方に延びる。第３部分２２ｃは、第１部分２２ａの車幅方向略中央から上方に延びる。第５光源２２は、第１光源１４および第２光源１６の上方に配置される。 The fifth light source 22 has a first portion 22a, a second portion 22b, and a third portion 22c. The first portion 22a extends in the vehicle width direction. The second portion 22b extends upward from the outer end of the first portion 22a in the vehicle width direction. The third portion 22c extends upward from approximately the center of the first portion 22a in the vehicle width direction. The fifth light source 22 is disposed above the first light source 14 and the second light source 16.

ベース部材２４は、透光カバー１２に対し略平行に広がる扁平な部材である。ベース部材２４は、第１光源１４～第５光源２２の灯具後方に配置され、灯具前方を向く面に第１光源１４～第５光源２２が搭載される。 The base member 24 is a flat member that extends approximately parallel to the translucent cover 12. The base member 24 is disposed behind the lamps of the first light source 14 to the fifth light source 22, and the first light source 14 to the fifth light source 22 are mounted on the surface facing forward of the lamp.

制御基板２６は、第１光源１４～第５光源２２の点消灯を制御する。制御基板２６は、コンピュータのＣＰＵやメモリをはじめとする素子や回路といったハードウェア構成を有する。また、コンピュータプログラム等によって実現されるソフトウェア構成を有する。制御基板２６は、ベース部材２４の灯具後方に配置されて、ベース部材２４に搭載される。 The control board 26 controls the turning on and off of the first light source 14 to the fifth light source 22. The control board 26 has a hardware configuration such as a computer's CPU, memory, and other elements and circuits. It also has a software configuration realized by a computer program or the like. The control board 26 is disposed behind the lamp on the base member 24 and is mounted on the base member 24.

インナーレンズ２８は、透光性を有し、第１光源１４～第５光源２２の灯具前方に配置されて第１光源１４～第５光源２２を覆う。第１光源１４～第５光源２２から出射される光は、インナーレンズ２８および透光カバー１２を透過して灯具前方に照射される。 The inner lens 28 is translucent and is disposed in front of the first light source 14 to the fifth light source 22, covering the first light source 14 to the fifth light source 22. The light emitted from the first light source 14 to the fifth light source 22 passes through the inner lens 28 and the translucent cover 12 and is irradiated in front of the lamp.

光反射部材３０は、線状部３０ａと、三角形状部３０ｂとを有する。線状部３０ａは、車幅方向に延びる。三角形状部３０ｂは、線状部３０ａの車幅方向外側の端部に頂点の１つが接続され、車幅方向外側に向かうにつれて上下に広がる。線状部３０ａは、灯具前方側から見て第１光源１４および第２光源１６を上下に二分するように配置される。三角形状部３０ｂは、灯具前方側から見て第３光源１８と第４光源２０との間に配置される。 The light reflecting member 30 has a linear portion 30a and a triangular portion 30b. The linear portion 30a extends in the vehicle width direction. The triangular portion 30b has one vertex connected to the end of the linear portion 30a on the outer side in the vehicle width direction, and expands vertically as it moves outward in the vehicle width direction. The linear portion 30a is positioned so as to vertically bisect the first light source 14 and the second light source 16 when viewed from the front side of the lamp. The triangular portion 30b is positioned between the third light source 18 and the fourth light source 20 when viewed from the front side of the lamp.

線状部３０ａは、灯具前方を向く面の略全体に光反射面３０ａ１を有する。三角形状部３０ｂは、線状部３０ａの車幅方向外側の端部から斜め上に延びる縁部と、当該端部から斜め下に延びる縁部とに光反射面３０ｂ１を有する。光反射面３０ｂ１は、光反射面３０ａ１の端部から連続している。したがって、光反射面３０ａ１および光反射面３０ｂ１は、互いに集合して９０度回転したＹ字状を形成している。例えば、線状部３０ａおよび三角形状部３０ｂは樹脂製であり、光反射面３０ａ１，３０ｂ１はアルミ蒸着等によって形成される。 Linear portion 30a has light reflecting surface 30a1 on almost the entire surface facing forward of the lamp. Triangular portion 30b has light reflecting surface 30b1 on an edge extending diagonally upward from the outer end of linear portion 30a in the vehicle width direction and on an edge extending diagonally downward from said end. Light reflecting surface 30b1 is continuous with the end of light reflecting surface 30a1. Therefore, light reflecting surface 30a1 and light reflecting surface 30b1 come together to form a Y shape rotated 90 degrees. For example, linear portion 30a and triangular portion 30b are made of resin, and light reflecting surfaces 30a1 and 30b1 are formed by aluminum deposition or the like.

また、三角形状部３０ｂは、灯具外部から進入する光を灯具外部に向けて反射するリフレックスリフレクタ３０ｂ２を有する。リフレックスリフレクタ３０ｂ２は、９０度回転したＶ字状であり、Ｖ字の頂点が車幅方向内側を向く。三角形状部３０ｂは、リフレックスリフレクタ３０ｂ２よりも車幅方向外側に、三角形状の開口部３０ｂ３を有する。開口部３０ｂ３には、三角形状のバックアップランプ３１が嵌め込まれる。バックアップランプ３１は、ベース部材２４に搭載される。 The triangular portion 30b also has a reflex reflector 30b2 that reflects light entering from outside the lamp toward the outside of the lamp. The reflex reflector 30b2 is V-shaped rotated 90 degrees, with the apex of the V facing inward in the vehicle width direction. The triangular portion 30b has a triangular opening 30b3 that is located outside the reflex reflector 30b2 in the vehicle width direction. A triangular backup lamp 31 is fitted into the opening 30b3. The backup lamp 31 is mounted on the base member 24.

第２灯具ユニット８は、光源８ａとインナーレンズ８ｂとが組み付けられた構造を有する。光源８ａは、例えば配線基板に複数の発光素子が敷設された構造を有する。インナーレンズ８ｂは、透光性を有し、光源８ａの灯具前方に配置されて光源８ａを覆う。第２灯具ユニット８は、ベース部材２４の灯具後方に配置されて、ベース部材２４に組み付けられる。第２灯具ユニット８の一部は、第５光源２２の第１部分２２ａより上方で且つ第３部分２２ｃよりも車幅方向内側に配置されて、灯具前方側から視認される。また、第２灯具ユニット８の他の一部は、第５光源２２の第２部分２２ｂと第３部分２２ｃとの間に配置されて、灯具前方側から視認される。また、第２灯具ユニット８のさらに他の一部は、第５光源２２の第２部分２２ｂと第３光源１８との間に配置されて、灯具前方側から視認される。 The second lamp unit 8 has a structure in which a light source 8a and an inner lens 8b are assembled. The light source 8a has a structure in which, for example, a plurality of light emitting elements are laid on a wiring board. The inner lens 8b has translucency and is disposed in front of the light source 8a to cover the light source 8a. The second lamp unit 8 is disposed behind the lamp on the base member 24 and assembled to the base member 24. A part of the second lamp unit 8 is disposed above the first part 22a of the fifth light source 22 and on the inside of the third part 22c in the vehicle width direction, and is visible from the front side of the lamp. Another part of the second lamp unit 8 is disposed between the second part 22b and the third part 22c of the fifth light source 22, and is visible from the front side of the lamp. Another part of the second lamp unit 8 is disposed between the second part 22b of the fifth light source 22 and the third light source 18, and is visible from the front side of the lamp.

続いて、車両用灯具１が備える発光部の形状について説明する。図２は、車両用灯具１の斜視図である。図３は、車両用灯具１の正面図である。車両用灯具１は、第１発光部３２、第２発光部３４、第３発光部３６および第４発光部３８を備える。第１発光部３２～第４発光部３８は、ケース２に収容されて透光カバー１２に向け光を照射する。したがって、各発光部から出射される光は、透光カバー１２を透過して灯具前方に向けて照射される。 Next, the shape of the light-emitting section of the vehicle lamp 1 will be described. FIG. 2 is a perspective view of the vehicle lamp 1. FIG. 3 is a front view of the vehicle lamp 1. The vehicle lamp 1 comprises a first light-emitting section 32, a second light-emitting section 34, a third light-emitting section 36, and a fourth light-emitting section 38. The first light-emitting section 32 to the fourth light-emitting section 38 are housed in the case 2 and irradiate light toward the translucent cover 12. Therefore, the light emitted from each light-emitting section passes through the translucent cover 12 and is irradiated toward the front of the lamp.

第１発光部３２は、第１長尺部３２ａと、第１突出部３２ｂとを有する。第１長尺部３２ａは、車幅方向に直線状に延びる。第１突出部３２ｂは、第１長尺部３２ａの車幅方向外側の端部から車幅方向と交わる方向に突出する。第１突出部３２ｂの先端は、第１長尺部３２ａよりも鉛直方向の第１側に位置する。本実施の形態において第１側は上方であり、第１突出部３２ｂは第１長尺部３２ａの端部から上方に突出している。また、本実施の形態の第１突出部３２ｂは、先端に向かうほど車幅方向外側に位置するように斜めに延びている。 The first light-emitting portion 32 has a first long portion 32a and a first protruding portion 32b. The first long portion 32a extends linearly in the vehicle width direction. The first protruding portion 32b protrudes from the end of the first long portion 32a on the outer side in the vehicle width direction in a direction intersecting with the vehicle width direction. The tip of the first protruding portion 32b is located on the first side in the vertical direction from the first long portion 32a. In this embodiment, the first side is upward, and the first protruding portion 32b protrudes upward from the end of the first long portion 32a. In this embodiment, the first protruding portion 32b extends obliquely so that it is located further outward in the vehicle width direction as it approaches the tip.

また、第１突出部３２ｂの幅Ｗ１ｂは、第１長尺部３２ａの幅Ｗ１ａより太い。第１長尺部３２ａの幅Ｗ１ａは、車幅方向と直交する方向の大きさの平均値または最大値である。第１突出部３２ｂの幅Ｗ１ｂは、第１突出部３２ｂの突出方向と直交する方向の大きさの平均値または最大値である。突出部の突出方向は、例えば突出部の基端側の辺Ｓ１（長尺部との境界線）の中心と、先端側の辺Ｓ２の中心とを結ぶ直線の延びる方向である。 The width W1b of the first protrusion 32b is greater than the width W1a of the first long portion 32a. The width W1a of the first long portion 32a is the average or maximum value of the size in the direction perpendicular to the vehicle width direction. The width W1b of the first protrusion 32b is the average or maximum value of the size in the direction perpendicular to the protruding direction of the first protrusion 32b. The protruding direction of the protrusion is, for example, the direction in which a straight line extends connecting the center of the side S1 (the boundary line with the long portion) on the base end side of the protrusion and the center of the side S2 on the tip end side.

第１長尺部３２ａは主に、第１光源１４の線状部３０ａより上方の部分から出射される光と、第２光源１６の線状部３０ａより上方の部分から出射される光とを灯具前方に照射する。第１突出部３２ｂは主に、第３光源１８から出射される光を灯具前方に照射する。なお、第１発光部３２は、おおよそ全体が同一平面上に位置して、平坦な発光面を構成している。 The first long portion 32a mainly irradiates the light emitted from the portion of the first light source 14 above the linear portion 30a and the light emitted from the portion of the second light source 16 above the linear portion 30a, toward the front of the lamp. The first protrusion 32b mainly irradiates the light emitted from the third light source 18, toward the front of the lamp. The first light-emitting portion 32 is located almost entirely on the same plane, forming a flat light-emitting surface.

The second long portion 34a extends linearly in the vehicle width direction. The second protruding portion 34b protrudes from the outer end of the second long portion 34a in the vehicle width direction in a direction intersecting with the vehicle width direction. The tip of the second protruding portion 34b is located on the first side in the vertical direction, i.e., above the second long portion 34a. Therefore, the second protruding portion 34b protrudes vertically to the same side as the first protruding portion 32b. Furthermore, the second protruding portion 34b in this embodiment extends obliquely so that it is located more outward in the vehicle width direction as it approaches the tip.

また、第２突出部３４ｂの幅Ｗ２ｂは、第２長尺部３４ａの幅Ｗ２ａより太い。第２長尺部３４ａの幅Ｗ２ａは、車幅方向と直交する方向の大きさの平均値または最大値である。第２突出部３４ｂの幅Ｗ２ｂは、第２突出部３４ｂの突出方向と直交する方向の大きさの平均値または最大値である。 The width W2b of the second protrusion 34b is greater than the width W2a of the second long portion 34a.

The tip of the third protruding portion 36b is located on the first side, i.e., above, the third long portion 36a. Therefore, the third protruding portion 36b protrudes vertically on the same side as the first protruding portion 32b and the second protruding portion 34b. Furthermore, the third protruding portion 36b in this embodiment extends obliquely so that it is located more outward in the vehicle width direction as it approaches the tip.

第３発光部３６は、第２長尺部３４ａよりも第１側つまり上方で且つ第２突出部３４ｂよりも車幅方向内側に配置される。第３長尺部３６ａは、第２長尺部３４ａの上方で第２長尺部３４ａに対して平行に延びる。第３突出部３６ｂは、第２突出部３４ｂよりも車幅方向内側で第２突出部３４ｂに対して略平行に延びる。 The third light-emitting portion 36 is disposed on the first side, i.e., above the second long portion 34a, and on the inner side in the vehicle width direction of the second protruding portion 34b. The third long portion 36a extends above the second long portion 34a and parallel to the second long portion 34a. The third protruding portion 36b extends on the inner side in the vehicle width direction of the second protruding portion 34b, and approximately parallel to the second protruding portion 34b.

また、本実施の形態の第２発光部３４は、第３発光部３６に対し透光カバー１２に近づく方向にずれて配置される。つまり、本実施の形態の車両用灯具１では、灯具の奥行き方向で第１発光部３２が最も手前に位置し、第２発光部３４が中間に位置し、第３発光部３６が最も奥側に位置する。また、第３長尺部３６ａは、第２長尺部３４ａよりも短く、第３長尺部３６ａの車幅方向内側の端部は、第２長尺部３４ａの車幅方向内側の端部よりも車幅方向外側に位置する。 In addition, the second light-emitting portion 34 in this embodiment is positioned offset in the direction approaching the translucent cover 12 relative to the third light-emitting portion 36. That is, in the vehicle lamp 1 of this embodiment, the first light-emitting portion 32 is located at the front end in the depth direction of the lamp, the second light-emitting portion 34 is located in the middle, and the third light-emitting portion 36 is located at the back end. In addition, the third long portion 36a is shorter than the second long portion 34a, and the inner end of the third long portion 36a in the vehicle width direction is located outward in the vehicle width direction than the inner end of the second long portion 34a in the vehicle width direction.

第３長尺部３６ａは主に、第５光源２２の第１部分２２ａから出射される光を灯具前方に照射する。第３突出部３６ｂは主に、第５光源２２の第３部分２２ｃから出射される光を灯具前方に照射する。なお、第３発光部３６は、おおよそ全体が同一平面上に位置して、平坦な発光面を構成している。 The third elongated portion 36a mainly irradiates the light emitted from the first portion 22a of the fifth light source 22 toward the front of the lamp. The third protrusion 36b mainly irradiates the light emitted from the third portion 22c of the fifth light source 22 toward the front of the lamp. The third light-emitting portion 36 is located almost entirely on the same plane, forming a flat light-emitting surface.

第４発光部３８は、第４長尺部３８ａと、第４突出部３８ｂとを有する。第４長尺部３８ａは、第１長尺部３２ａよりも鉛直方向の第１側とは反対の第２側で第１長尺部３２ａに沿って延びる。本実施の形態において、第２側は下方である。第４突出部３８ｂは、第４長尺部３８ａの車幅方向外側の端部から車幅方向と交わる方向に突出する。第４突出部３８ｂの先端は、第４長尺部３８ａよりも第２側つまり下方に位置する。したがって、第４突出部３８ｂは、鉛直方向で第１突出部３２ｂ、第２突出部３４ｂおよび第３突出部３６ｂとは逆側に突出している。また、本実施の形態の第４突出部３８ｂは、先端に向かうほど車幅方向外側に位置するように延びている。 The fourth light-emitting portion 38 has a fourth long portion 38a and a fourth protruding portion 38b. The fourth long portion 38a extends along the first long portion 32a on the second side opposite to the first side in the vertical direction from the first long portion 32a. In this embodiment, the second side is downward. The fourth protruding portion 38b protrudes from the end of the fourth long portion 38a on the outer side in the vehicle width direction in a direction intersecting with the vehicle width direction. The tip of the fourth protruding portion 38b is located on the second side, that is, downward, from the fourth long portion 38a. Therefore, the fourth protruding portion 38b protrudes in the vertical direction on the opposite side to the first protruding portion 32b, the second protruding portion 34b, and the third protruding portion 36b. In addition, the fourth protruding portion 38b in this embodiment extends so that it is located more outward in the vehicle width direction as it approaches the tip.

また、第４突出部３８ｂの幅Ｗ４ｂは、第４長尺部３８ａの幅Ｗ４ａよりも太い。第４長尺部３８ａの幅Ｗ４ａは、車幅方向と直交する方向の大きさの平均値または最大値である。第４突出部３８ｂの幅Ｗ４ｂは、第４突出部３８ｂの突出方向と直交する方向の大きさの平均値または最大値である。第１長尺部３２ａおよび第４長尺部３８ａは、ほぼ同じ長さであり、透光カバー１２に対する距離もほぼ同じである。したがって、第１発光部３２および第４発光部３８は、互いに集合して９０度回転したＹ字を形成している。 The width W4b of the fourth protrusion 38b is greater than the width W4a of the fourth long portion 38a. The width W4a of the fourth long portion 38a is the average or maximum value of the size in the direction perpendicular to the vehicle width direction. The width W4b of the fourth protrusion 38b is the average or maximum value of the size in the direction perpendicular to the protrusion direction of the fourth protrusion 38b. The first long portion 32a and the fourth long portion 38a are approximately the same length, and are also approximately the same distance from the translucent cover 12. Therefore, the first light-emitting portion 32 and the fourth light-emitting portion 38 come together to form a Y-shape rotated 90 degrees.

第４長尺部３８ａは主に、第１光源１４の線状部３０ａより下方の部分から出射される光と、第２光源１６の線状部３０ａより下方の部分から出射される光とを灯具前方に照射する。第４突出部３８ｂは主に、第４光源２０から出射される光を灯具前方に照射する。なお、第４発光部３８は、おおよそ全体が同一平面上に位置して、平坦な発光面を構成している。 The fourth elongated portion 38a mainly irradiates the light emitted from the portion of the first light source 14 below the linear portion 30a and the light emitted from the portion of the second light source 16 below the linear portion 30a, toward the front of the lamp. The fourth protrusion 38b mainly irradiates the light emitted from the fourth light source 20, toward the front of the lamp. The fourth light-emitting portion 38 is located almost entirely on the same plane, forming a flat light-emitting surface.

また、車両用灯具１は、第１長尺部３２ａと第４長尺部３８ａとの間で車幅方向に延びる非発光部４０を有する。非発光部４０は、線状部３０ａの光反射面３０ａ１で構成される。なお、第１長尺部３２ａおよび第４長尺部３８ａは、非発光部４０の車幅方向内側の端部よりも車幅方向内側まで延びて互いに接続されている。第１突出部３２ｂおよび第４突出部３８ｂの車幅方向外側には、三角形状部３０ｂの光反射面３０ｂ１、リフレックスリフレクタ３０ｂ２およびバックアップランプ３１がこの順に配置される。 The vehicle lamp 1 also has a non-light-emitting portion 40 that extends in the vehicle width direction between the first long portion 32a and the fourth long portion 38a. The non-light-emitting portion 40 is formed by the light-reflecting surface 30a1 of the linear portion 30a. The first long portion 32a and the fourth long portion 38a extend further inward in the vehicle width direction than the inner end of the non-light-emitting portion 40 in the vehicle width direction and are connected to each other. On the vehicle width outer side of the first protrusion 32b and the fourth protrusion 38b, the light-reflecting surface 30b1 of the triangular portion 30b, the reflex reflector 30b2, and the backup lamp 31 are arranged in this order.

また、本実施の形態の第１突出部３２ｂは、光拡散部４２を有する。光拡散部４２は、例えばインナーレンズ２８に設けられるスリットや反射ステップ等の光学要素で構成される。また、本実施の形態では、第２突出部３４ｂおよび第３突出部３６ｂも光拡散部４２を有する。各突出部から照射される光の一部は、光拡散部４２によって進行方向が変えられる。なお、第４突出部３８ｂにも光拡散部４２が設けられてもよい。 The first protrusion 32b in this embodiment also has a light diffusion section 42. The light diffusion section 42 is composed of optical elements such as slits and reflective steps provided in the inner lens 28. In this embodiment, the second protrusion 34b and the third protrusion 36b also have a light diffusion section 42. The light diffusion section 42 changes the direction of travel of a portion of the light irradiated from each protrusion. The fourth protrusion 38b may also be provided with a light diffusion section 42.

また、本実施の形態の車両用灯具１は、第５発光部４４、第６発光部４６および第７発光部４８を有する。第５発光部４４は、第３長尺部３６ａより上方で且つ第３突出部３６ｂより車幅方向内側に配置される。第６発光部４６は、第２突出部３４ｂと第３突出部３６ｂとの間に配置される。第７発光部４８は、第１突出部３２ｂと第２突出部３４ｂとの間に配置される。第５発光部４４、第６発光部４６および第７発光部４８は、第２灯具ユニット８の光源８ａから出射される光を灯具前方に照射する。 The vehicle lamp 1 of this embodiment also has a fifth light-emitting portion 44, a sixth light-emitting portion 46, and a seventh light-emitting portion 48. The fifth light-emitting portion 44 is disposed above the third long portion 36a and on the inside in the vehicle width direction of the third protrusion 36b. The sixth light-emitting portion 46 is disposed between the second protrusion 34b and the third protrusion 36b. The seventh light-emitting portion 48 is disposed between the first protrusion 32b and the second protrusion 34b. The fifth light-emitting portion 44, the sixth light-emitting portion 46, and the seventh light-emitting portion 48 irradiate the light emitted from the light source 8a of the second lamp unit 8 forward of the lamp.

一例として、第１発光部３２および第４発光部３８は、テールランプ機能およびターンランプ機能を発揮する。また、第２発光部３４および第３発光部３６は、テールランプ機能およびストップランプ機能を発揮する。第５発光部４４～第７発光部４８は、ストップランプ機能を発揮する。 As an example, the first light-emitting element 32 and the fourth light-emitting element 38 function as a tail lamp and a turn signal lamp. The second light-emitting element 34 and the third light-emitting element 36 function as a tail lamp and a stop lamp. The fifth light-emitting element 44 to the seventh light-emitting element 48 function as a stop lamp.

以上説明したように、本実施の形態に係る車両用灯具１は、平面状の透光カバー１２を有するケース２と、ケース２に収容され、透光カバー１２に向け光を照射する第１発光部３２および第２発光部３４とを備える。第１発光部３２は、車幅方向に延びる第１長尺部３２ａと、第１長尺部３２ａの車幅方向外側の端部から車幅方向と交わる方向に突出し、且つ第１長尺部３２ａの幅Ｗ１ａより太い幅Ｗ１ｂを有する第１突出部３２ｂとを有する。第２発光部３４は、車幅方向に延びる第２長尺部３４ａと、第２長尺部３４ａの車幅方向外側の端部から車幅方向と交わる方向に突出し、且つ第２長尺部３４ａの幅Ｗ２ａより太い幅Ｗ２ｂを有する第２突出部３４ｂとを有する。第１突出部３２ｂの先端は、第１長尺部３２ａよりも鉛直方向の第１側に位置し、第２突出部３４ｂの先端は、第２長尺部３４ａよりも第１側に位置する。第２発光部３４は、第１長尺部３２ａよりも第１側で且つ第１突出部３２ｂよりも車幅方向内側に配置される。 As described above, the vehicle lamp 1 according to the present embodiment includes a case 2 having a planar translucent cover 12, and a first light-emitting portion 32 and a second light-emitting portion 34 housed in the case 2 and irradiating light toward the translucent cover 12. The first light-emitting portion 32 has a first long portion 32a extending in the vehicle width direction, and a first protruding portion 32b protruding from the outer end of the first long portion 32a in the vehicle width direction in a direction intersecting with the vehicle width direction and having a width W1b larger than the width W1a of the first long portion 32a. The second light-emitting portion 34 has a second long portion 34a extending in the vehicle width direction, and a second protruding portion 34b protruding from the outer end of the second long portion 34a in the vehicle width direction in a direction intersecting with the vehicle width direction and having a width W2b larger than the width W2a of the second long portion 34a. The tip of the first protrusion 32b is located on the first vertical side of the first long portion 32a, and the tip of the second protrusion 34b is located on the first side of the second long portion 34a. The second light-emitting portion 34 is disposed on the first side of the first long portion 32a and on the inner side of the first protrusion 32b in the vehicle width direction.

透光カバー１２が平面状であると、車両用灯具１の真横から発光部を視認することが困難である。これに対し、第１発光部３２は、車幅方向に延びる第１長尺部３２ａの幅Ｗ１ａよりも、第１長尺部３２ａの車幅方向外側の端部から突出する第１突出部３２ｂの幅Ｗ１ｂの方が太い。これにより、車両用灯具１における車幅方向外側の輝度を高めやすくすることができる。この結果、車両の側方に位置する他車両や歩行者に対して自車両の存在や状態を認識させやすくすることができる。よって、車両用灯具１の自車表示機能を高めることができる。 If the light-transmitting cover 12 is flat, it is difficult to see the light-emitting portion from directly to the side of the vehicle lamp 1. In contrast, the width W1b of the first protruding portion 32b protruding from the outer end of the first elongated portion 32a in the vehicle width direction of the first light-emitting portion 32 is wider than the width W1a of the first elongated portion 32a extending in the vehicle width direction. This makes it easier to increase the brightness of the vehicle lamp 1 on the outer side in the vehicle width direction. As a result, it is easier for other vehicles and pedestrians located to the side of the vehicle to recognize the presence and condition of the vehicle. This improves the vehicle display function of the vehicle lamp 1.

また、車両用灯具１は、第１発光部３２に加えて第２発光部３４を備える。第２発光部３４は、第１発光部３２と同様に略Ｌ字状であり、第１長尺部３２ａより上方で且つ第１突出部３２ｂよりも車幅方向内側に配置される。つまり、第１発光部３２のＬ字の窪みに、第１発光部３２と相似形状の第２発光部３４が収まっている。これにより、車両用灯具１の誘目性を高めて、より自車表示機能を向上させることができる。また、第２発光部３４を設けることで、車両用灯具１全体での発光面積を増やすことができる。これによっても、車両用灯具１の自車表示機能を高めることができる。さらに、第２発光部３４を第１発光部３２のＬ字の窪みに配置することで、車両用灯具１の大型化を抑制しながら発光面積を増やすことができる。 The vehicle lamp 1 also includes a second light emitting portion 34 in addition to the first light emitting portion 32. The second light emitting portion 34 is substantially L-shaped like the first light emitting portion 32, and is disposed above the first long portion 32a and inward in the vehicle width direction from the first protruding portion 32b. In other words, the second light emitting portion 34, which has a similar shape to the first light emitting portion 32, is contained in the L-shaped recess of the first light emitting portion 32. This increases the visibility of the vehicle lamp 1 and improves the vehicle display function. In addition, by providing the second light emitting portion 34, the light emitting area of the entire vehicle lamp 1 can be increased. This also improves the vehicle display function of the vehicle lamp 1. Furthermore, by disposing the second light emitting portion 34 in the L-shaped recess of the first light emitting portion 32, the light emitting area can be increased while suppressing the increase in size of the vehicle lamp 1.

また、本実施の形態の第１発光部３２は、第２発光部３４に対し透光カバー１２に近づく方向にずれて配置される。これにより、車両用灯具１に奥行き感を持たせることができ、車両用灯具１の誘目性をより高めることができる。この結果、車両用灯具１の自車表示機能をより向上させることができる。 In addition, in this embodiment, the first light-emitting portion 32 is positioned offset from the second light-emitting portion 34 in the direction closer to the translucent cover 12. This gives the vehicle lamp 1 a sense of depth, and makes the vehicle lamp 1 more conspicuous. As a result, the vehicle display function of the vehicle lamp 1 can be further improved.

また、本実施の形態の第１突出部３２ｂは、光拡散部４２を有する。これにより、車両の側方に位置する他車両や歩行者に対して第１突出部３２ｂの発光を視認させやすくすることができる。よって、車両用灯具１の自車表示機能をより高めることができる。 In addition, the first protrusion 32b in this embodiment has a light diffusion section 42. This makes it easier for other vehicles and pedestrians located to the side of the vehicle to see the light emitted from the first protrusion 32b. This further enhances the vehicle display function of the vehicle lamp 1.

また、本実施の形態の車両用灯具１は、第３発光部３６をさらに備える。第３発光部３６は、車幅方向に延びる第３長尺部３６ａと、第３長尺部３６ａの車幅方向外側の端部から車幅方向と交わる方向に突出し、且つ第３長尺部３６ａの幅Ｗ３ａより太い幅Ｗ３ｂを有する第３突出部３６ｂとを有する。第３突出部３６ｂの先端は、第３長尺部３６ａよりも第１側に位置する。第３発光部３６は、第２長尺部３４ａよりも第１側で且つ第２突出部３４ｂよりも車幅方向内側に配置される。 The vehicle lamp 1 of this embodiment further includes a third light-emitting portion 36. The third light-emitting portion 36 includes a third long portion 36a extending in the vehicle width direction, and a third protruding portion 36b protruding from the outer end of the third long portion 36a in the vehicle width direction in a direction intersecting with the vehicle width direction and having a width W3b larger than the width W3a of the third long portion 36a. The tip of the third protruding portion 36b is located on the first side of the third long portion 36a. The third light-emitting portion 36 is disposed on the first side of the second long portion 34a and on the inner side of the second protruding portion 34b in the vehicle width direction.

第３発光部３６は、第１発光部３２および第２発光部３４と同様に略Ｌ字状であり、第２長尺部３４ａより上方で且つ第２突出部３４ｂよりも車幅方向内側に配置される。つまり、第２発光部３４のＬ字の窪みに、第２発光部３４と相似形状の第３発光部３６が収まっている。これにより、車両用灯具１の誘目性をより高めて、より自車表示機能を向上させることができる。また、第３発光部３６を設けることで、車両用灯具１全体での発光面積をより増やすことができる。これによっても、車両用灯具１の自車表示機能を高めることができる。さらに、第３発光部３６を第２発光部３４のＬ字の窪みに配置することで、車両用灯具１の大型化を抑制しながら発光面積を増やすことができる。 The third light-emitting portion 36 is substantially L-shaped like the first light-emitting portion 32 and the second light-emitting portion 34, and is disposed above the second long portion 34a and inward in the vehicle width direction from the second protruding portion 34b. In other words, the third light-emitting portion 36, which has a similar shape to the second light-emitting portion 34, is contained in the L-shaped recess of the second light-emitting portion 34. This makes it possible to further increase the visibility of the vehicle lamp 1 and improve the vehicle display function. In addition, by providing the third light-emitting portion 36, the light-emitting area of the entire vehicle lamp 1 can be further increased. This also improves the vehicle display function of the vehicle lamp 1. Furthermore, by disposing the third light-emitting portion 36 in the L-shaped recess of the second light-emitting portion 34, the light-emitting area can be increased while preventing the vehicle lamp 1 from becoming larger.

また、本実施の形態の第２発光部３４は、第３発光部３６に対し透光カバー１２に近づく方向にずれて配置される。これにより、車両用灯具１により奥行き感を持たせることができ、車両用灯具１の誘目性をより高めることができる。この結果、車両用灯具１の自車表示機能をより向上させることができる。 In addition, in this embodiment, the second light-emitting portion 34 is positioned offset from the third light-emitting portion 36 in the direction closer to the translucent cover 12. This allows the vehicle lamp 1 to have a greater sense of depth, and the vehicle lamp 1 can be made more conspicuous. As a result, the vehicle display function of the vehicle lamp 1 can be further improved.

また、本実施の形態の車両用灯具１は、第４発光部３８を備える。第４発光部３８は、第１長尺部３２ａよりも鉛直方向の第１側とは反対の第２側で第１長尺部３２ａに沿って延びる第４長尺部３８ａと、第４長尺部３８ａの車幅方向外側の端部から車幅方向と交わる方向に突出し、且つ第４長尺部３８ａの幅Ｗ４ａより太い幅Ｗ４ｂを有する第４突出部３８ｂとを有する。第４突出部３８ｂの先端は、第４長尺部３８ａよりも第２側に位置する。これにより、車両用灯具１の誘目性をより高めて、より自車表示機能を向上させることができる。また、第４発光部３８を設けることで、車両用灯具１全体での発光面積をより増やすことができる。これによっても、車両用灯具１の自車表示機能を高めることができる。 The vehicle lamp 1 of this embodiment also includes a fourth light-emitting section 38. The fourth light-emitting section 38 has a fourth long section 38a that extends along the first long section 32a on the second side opposite to the first side in the vertical direction from the first long section 32a, and a fourth protruding section 38b that protrudes from the outer end of the fourth long section 38a in the vehicle width direction in a direction intersecting with the vehicle width direction and has a width W4b that is wider than the width W4a of the fourth long section 38a. The tip of the fourth protruding section 38b is located on the second side of the fourth long section 38a. This makes it possible to further increase the visibility of the vehicle lamp 1 and further improve the vehicle display function. In addition, by providing the fourth light-emitting section 38, the light-emitting area of the entire vehicle lamp 1 can be further increased. This also improves the vehicle display function of the vehicle lamp 1.

また、本実施の形態の第１突出部３２ｂは、先端に向かうほど車幅方向外側に位置するように延びる。第４突出部３８ｂは、先端に向かうほど車幅方向外側に位置するように延びる。これにより、車両用灯具１の誘目性をより高めて、より自車表示機能を向上させることができる。 In addition, in this embodiment, the first protrusion 32b extends so that it is positioned further outward in the vehicle width direction as it approaches the tip. The fourth protrusion 38b extends so that it is positioned further outward in the vehicle width direction as it approaches the tip. This makes the vehicle lamp 1 more conspicuous and improves its vehicle display function.

また、本実施の形態の車両用灯具１は、第１長尺部３２ａと第４長尺部３８ａとの間で車幅方向に延びる非発光部４０を有する。これにより、車両用灯具１の誘目性をより高めて、より自車表示機能を向上させることができる。 The vehicle lamp 1 of this embodiment also has a non-light-emitting section 40 that extends in the vehicle width direction between the first long section 32a and the fourth long section 38a. This makes the vehicle lamp 1 more conspicuous and improves its vehicle display function.

なお、本実施の形態では、鉛直方向の第１側を上方、第２側を下方としているが、これに限らず第１側を下方、第２側を上方としてもよい。 In this embodiment, the first side in the vertical direction is the upper side and the second side is the lower side, but this is not limited thereto, and the first side may be the lower side and the second side may be the upper side.
