そこで、本願発明者は、上述のような複数の点発光を行う場合、複数点の点消灯の組み合わせにより種々の光らせ方を実現可能であることを知見した。
しかしながら、屋外を走行する車両において、点灯による表示を行う場合、昼間は、発光部分に太陽光が直射するため、点灯箇所の輝度が不足してしまい、歩行者や対向車の運転者などに認識させることが困難となることがあった。また、輝度不足を補うために、点灯箇所が高輝度となるように電流値を設定した場合であっても、被視認性が十分に得られなかった。 Therefore, the inventors of the present application have found that when a plurality of points of light are emitted as described above, it is possible to realize various lighting methods by combining the lighting and extinguishing of the plurality of points.
However, when lighting displays are used in vehicles driving outdoors, the light-emitting areas are exposed to direct sunlight during the daytime, resulting in insufficient brightness at the light-emitting areas. It was sometimes difficult to make Further, even when the current value is set so that the lighting portion has high luminance in order to compensate for the lack of luminance, sufficient visibility cannot be obtained.

本発明は、上記問題に着目して成されたもので、視認性に優れる車両用光学装置を提供することを目的とする。 SUMMARY OF THE INVENTION It is an object of the present invention to provide a vehicular optical device having excellent visibility.

上述の目的を達成するため、本開示の車両用光学装置は、複数に区画されて点消灯可能な区画部を有し、点灯時に光を車両外方に照射する光照射部と、前記光照射部の前面に沿って設けられ、前記区画部の少なくとも上側に配置された遮光部材と、を備える車両用光学装置とした。 In order to achieve the above-described object, the vehicle optical device of the present disclosure includes a light irradiation unit that has a plurality of partitions that can be turned on and off, and that emits light to the outside of the vehicle when the light is turned on; and a light shielding member provided along the front surface of the partition and arranged at least above the partition.

本開示の車両用光学装置では、光照射部の前面に沿って区画部の少なくとも上側に遮光部材を設けたため、区画部への太陽光の直射を抑え、視認性を確保できる。 In the vehicular optical device of the present disclosure, since the light shielding member is provided at least above the partition along the front surface of the light irradiation unit, it is possible to suppress direct sunlight to the partition and ensure visibility.

（実施の形態１）
図１は実施の形態１の車両用光学装置１００を搭載した車両ＭＶの前部を示す斜視図である。
実施の形態１の車両用光学装置１００は、車両ＭＶの前面部分に設けられ、ルーバー（遮光部材）１１０と光を車両前方に照射する光照射部３００とを備えている。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.
(Embodiment 1)
FIG. 1 is a perspective view showing a front portion of a vehicle MV equipped with the vehicle optical device 100 of Embodiment 1. FIG.
A vehicle optical device 100 according to Embodiment 1 is provided in the front portion of a vehicle MV, and includes a louver (light shielding member) 110 and a light irradiation section 300 that irradiates light forward of the vehicle.

ルーバー１１０は、図１に示す例では、水平方向に延在されて上下方向に所定の間隔を空けて複数並設されている。なお、図において矢印ＦＲが車両前方を示し、矢印Ｌが車両左方向を示し、矢印Ｒが車両右方向を示す。 In the example shown in FIG. 1, the louvers 110 extend horizontally and are arranged side by side at predetermined intervals in the vertical direction. In the drawings, an arrow FR indicates the front of the vehicle, an arrow L indicates the left direction of the vehicle, and an arrow R indicates the right direction of the vehicle.

また、ルーバー１１０は、車幅方向に沿って車両前後方向に湾曲した形状に形成されている。すなわち、図２は車両用光学装置１００の要部を上方から見た平面図であり、ルーバー１１０を含む車両前面部分は、車幅方向で車両中央から車両外側に向かうほど、車両後方に位置するように湾曲した形状に形成されている。 Also, the louver 110 is formed in a shape curved in the vehicle front-rear direction along the vehicle width direction. That is, FIG. 2 is a top plan view of the essential parts of the vehicle optical device 100, and the front portion of the vehicle including the louver 110 is positioned at the rear of the vehicle as it goes from the center of the vehicle toward the outside of the vehicle in the vehicle width direction. It is formed into a curved shape.

光照射部３００は、複数に区画された区画部１３０を、それぞれ、独立して点消灯可能としている。すなわち、詳細は後述するが、区画部１３０は、ＬＥＤ基板２２０に設けられたＬＥＤ（light emitting diode）などの発光素子２３０の光が導光体２４０を介して導かれ、反射板２５０及びレンズ部材２１０により、車両前方に拡散あるいは拡幅して照射可能となっている。そして、各発光素子２３０は、後述するドライバ２６０によりそれぞれ、独立して点灯、消灯可能となっている（以下、点消灯という）。なお、発光素子２３０のうち、ＬＥＤ基板２２０の前端部に配置された発光素子２３０ａは、反射板２５０の反射面に対向して配置され、導光体２４０を介すること無く、直接、反射面に光を照射可能に配置されている。 The light irradiation unit 300 enables each of the divided sections 130 to be turned on and off independently. That is, although the details will be described later, light from a light emitting element 230 such as an LED (light emitting diode) provided on an LED substrate 220 is guided through a light guide 240 to the partitioning portion 130, and the reflector 250 and the lens member 210, the light can be diffused or widened in front of the vehicle and irradiated. Each of the light emitting elements 230 can be turned on and off independently by a driver 260 described later (hereinafter referred to as lighting and extinguishing). Among the light emitting elements 230, the light emitting element 230a arranged at the front end portion of the LED board 220 is arranged facing the reflecting surface of the reflecting plate 250, and is directly applied to the reflecting surface without the light guide 240 intervening. It is arranged so that it can be irradiated with light.

また、本実施の形態１では、区画部１３０は、各ルーバー１１０の下側に配置され、上下方向で、ルーバー１１０の間隔で区画され、かつ、車幅方向（左右方向）にも一定幅で複数に区画されている。すなわち、光照射部３００を上下方向および左右方向に複数に区画して区画部１３０が形成されている。そして、各区画部１３０に、レンズ部材２１０や反射板２５０が設けられ、区画部１３０が独立して点消灯する１つの領域として形成されている。 Further, in the first embodiment, the partitioning portion 130 is arranged below each louver 110, is partitioned vertically at intervals between the louvers 110, and has a constant width in the vehicle width direction (horizontal direction). divided into multiple sections. That is, the light irradiation section 300 is partitioned into a plurality of sections in the vertical direction and the horizontal direction to form the partition section 130 . A lens member 210 and a reflector 250 are provided in each partition 130, and the partition 130 is formed as one region that is independently turned on and off.

さらに、本実施の形態１では、ルーバー１１０とレンズ部材２１０は、透明樹脂と遮光樹脂とによる二色成形や多色成形により一体的に形成されている。そして、ルーバー１１０は、遮光樹脂により形成され、レンズ部材２１０が透明樹脂により形成されている。したがって、レンズ部材２１０は、図３に示す例では、アウタレンズとして機能する。そして、ルーバー１１０と一体のレンズ部材２１０の後方にはハウジング２９０が設けられ、このハウジング２９０とレンズ部材２１０とにより灯室２８０が形成されている。このように灯室２８０を形成するレンズ部材２１０にルーバー１１０が一体に形成されているため、灯室２８０へのゴミ、埃、虫、水の浸入を防止することができる。 Furthermore, in Embodiment 1, the louver 110 and the lens member 210 are integrally formed by two-color molding or multi-color molding using a transparent resin and a light shielding resin. The louver 110 is made of light shielding resin, and the lens member 210 is made of transparent resin. Therefore, lens member 210 functions as an outer lens in the example shown in FIG. A housing 290 is provided behind the lens member 210 integrated with the louver 110 , and the housing 290 and the lens member 210 form a lamp chamber 280 . Since the louver 110 is formed integrally with the lens member 210 that forms the lamp chamber 280 in this way, it is possible to prevent dirt, dust, insects, and water from entering the lamp chamber 280 .

なお、図６に示す例のように、ルーバー１１０とレンズ部材２１０とを一体に形成しない場合には、図５に示すように、車両前面部分をアウタレンズ部材２７０により覆い、このアウタレンズ部材２７０とその後方のハウジングとで灯室を形成する。この場合、レンズ部材２１０はインナレンズとして機能する。 When the louver 110 and the lens member 210 are not integrally formed as in the example shown in FIG. 6, the front portion of the vehicle is covered with an outer lens member 270 as shown in FIG. The housing on the other side forms a lamp chamber. In this case, the lens member 210 functions as an inner lens.

さらに、実施の形態１の車両用光学装置１００では、複数の区画部１３０から光の照射を行うにあたり、領域の違いにより異なる機能が与えられている。
すなわち、車両用光学装置１００では、区画部１３０が形成された全領域を、光を車両前方に照射可能な光照射部３００としている。そして、光照射部３００には、図４Ａに示す前照灯駆動領域３１０と、図４Ｂに示すＤＲＬ駆動領域３２０と、図４Ｃに示す情報表示領域３３０と、が設定されている。 Furthermore, in the vehicular optical device 100 of Embodiment 1, different functions are given depending on the difference in the areas when light is emitted from the plurality of partitions 130 .
That is, in the vehicular optical device 100, the entire region in which the partition section 130 is formed serves as the light irradiation section 300 capable of irradiating light forward of the vehicle. A headlamp drive region 310 shown in FIG. 4A, a DRL drive region 320 shown in FIG. 4B, and an information display region 330 shown in FIG. 4C are set in the light irradiation unit 300 .

前照灯駆動領域３１０は、点灯時に前照灯として駆動する領域である。また、ＤＲＬ駆動領域３２０は、点灯時にデイタイムランニングライトとして駆動する領域である。また、情報表示領域３３０は、方向指示などの信号を含み、車外に対する何らかの信号あるいは情報を表示する領域である。なお、各領域３１０，３２０，３３０において、共通の区画部１３０を異なる領域と共用してもよい。 The headlamp drive area 310 is an area that is driven as a headlamp when lit. Also, the DRL drive area 320 is an area that is driven as a daytime running light when lit. Further, the information display area 330 is an area for displaying some kind of signal or information to the outside of the vehicle, including a signal such as a direction indication. In addition, in each area|region 310,320,330, you may share the common division part 130 with a different area|region.

（光源ユニット）
次に、各区画部１３０を点消灯させるための構造について、図３に基づいて詳細に説明する。区画部１３０のレンズ部材２１０の車両後方位置には、反射板２５０が設けられている。そして、ＬＥＤ基板２２０及び導光体２４０は、光源ユニット２００として一体化され、ハウジング２９０に支持されている。このレンズ部材２１０は、反射板２５０で反射された発光素子２３０の光を、レンズを介して車両前方へ照射するもので、その前面２１０ａが発光部として発光する。 (light source unit)
Next, a structure for turning on/off each section 130 will be described in detail with reference to FIG. A reflector 250 is provided at the vehicle rear position of the lens member 210 of the partition portion 130 . The LED board 220 and the light guide 240 are integrated as the light source unit 200 and supported by the housing 290 . The lens member 210 irradiates the light of the light emitting element 230 reflected by the reflector 250 forward of the vehicle through the lens, and the front surface 210a of the lens member 210 emits light as a light emitting portion.

ＬＥＤ基板２２０は、発光素子２３０とドライバ２６０を備える。発光素子２３０は、上下左右に並設された区画部１３０の上下方向の一列である縦列の区画部１３０と同数のものがＬＥＤ基板２２０の下面に車両前後方向に一列に設けられている。すなわち、図３では、区画部１３０が上下方向に５箇所に設けられており、ＬＥＤ基板２２０には、５個の発光素子２３０が設けられている。 The LED board 220 includes light emitting elements 230 and drivers 260 . The light emitting elements 230 are arranged in a row on the lower surface of the LED substrate 220 in the longitudinal direction of the vehicle in the same number as the partitions 130 arranged vertically and horizontally. That is, in FIG. 3 , the partitions 130 are provided at five locations in the vertical direction, and the LED substrate 220 is provided with five light emitting elements 230 .

ドライバ２６０は、各発光素子２３０を独立して点消灯可能としている。すなわち、１個の光源ユニット２００により縦一列の区画部１３０を点消灯させるようになっている。
また、ドライバ２６０は、発光素子２３０の全て、あるいは一部の調光及び調色可能としている。なお、図ではドライバ２６０を、文字及び枠で表示しているが、ドライバ２６０は、ＬＥＤ基板２２０に実装されている。また、ドライバ２６０は、ＬＥＤ基板２２０以外の部位に設けてもよい。 The driver 260 enables each light emitting element 230 to be turned on and off independently. That is, one light source unit 200 turns on and off the partitions 130 arranged in a vertical line.
In addition, the driver 260 is capable of adjusting all or part of the light emitting elements 230 in terms of brightness and color. Although the driver 260 is indicated by letters and frames in the drawing, the driver 260 is mounted on the LED board 220 . Also, the driver 260 may be provided at a portion other than the LED substrate 220 .

導光体２４０は、発光素子２３０の光を、区画部１３０の後方の反射板２５０の反射面に導くもので、本実施の形態１では、導光体２４０は、アクリルなどの透明樹脂やグラスファイバーなどにより形成されている。そして、導光体２４０は、上部が板状の支持部材２４１により支持され、かつ、上端面が発光素子２３０からの光の入射口となって発光素子２３０に対向して配置され、下端部が光の出射口２４０ａとなる。 The light guide 240 guides the light from the light emitting element 230 to the reflecting surface of the reflector 250 behind the partition section 130. In the first embodiment, the light guide 240 is made of transparent resin such as acrylic or glass. It is made of fiber or the like. The light guide 240 has an upper portion supported by a plate-shaped support member 241, an upper end surface serving as an entrance for light from the light emitting element 230, and facing the light emitting element 230, and a lower end portion It becomes the light exit port 240a.

次に、導光体２４０から出射された光を車両外部に反射する反射板２５０及びレンズ部材２１０について説明する。
反射板２５０は、お碗状に上方が開放され、さらに、車両前方が開放された形状に形成され、放物面を基本とする反射面を有している。なお、反射板２５０の上部を囲む板状の部分は、その上方に設けられた反射板２５０の下面を用いてもよい。 Next, the reflecting plate 250 and the lens member 210 that reflect the light emitted from the light guide 240 to the outside of the vehicle will be described.
The reflecting plate 250 is formed in a bowl-like shape with an open top and an open front side of the vehicle, and has a reflecting surface based on a paraboloid. The plate-like portion surrounding the upper portion of the reflector 250 may use the lower surface of the reflector 250 provided above.

そして、導光体２４０の下端部の出射口２４０ａが、反射板２５０の反射面に対向して配置されている。よって、導光体２４０の下端部の出射口２４０ａから出射された光は、反射板２５０で反射され、レンズ部材２１０のレンズを通って車両前方に向かうようになっている。 An exit port 240 a at the lower end of the light guide 240 is arranged to face the reflecting surface of the reflecting plate 250 . Therefore, the light emitted from the emission port 240a at the lower end of the light guide 240 is reflected by the reflector 250, passes through the lens of the lens member 210, and travels forward of the vehicle.

以上説明した光源ユニット２００は、前述したように車両前面部分の各区画部１３０の後方に配置されており、発光素子２３０の光が各区画部１３０から車両前方に照射される。 The light source unit 200 described above is arranged behind each partition 130 in the front portion of the vehicle as described above, and the light from the light emitting element 230 is emitted from each partition 130 to the front of the vehicle.

次に、ドライバ２６０の制御に基づく前述した光照射部３００の点灯駆動について説明する。実施の形態１の車両用光学装置１００では、車両前面部分において上下方向と左右方向とに複数並設された区画部１３０がそれぞれ独立して点消灯可能となっている。そこで、ドライバ２６０は、単に車両前方を照明する他に、所定の区画部１３０を選択的に点消灯することにより、図形表示や文字表示が可能である。以下、詳述する。 Next, lighting driving of the above-described light irradiation unit 300 based on the control of the driver 260 will be described. In the vehicular optical device 100 of Embodiment 1, a plurality of division portions 130 arranged in parallel in the vertical direction and the horizontal direction in the front portion of the vehicle can be turned on and off independently. Therefore, the driver 260 can display graphics and characters by selectively turning on and off the predetermined partitions 130 in addition to simply illuminating the front of the vehicle. Details will be described below.

まず、前照灯駆動領域３１０（図４Ａ参照）と、ＤＲＬ駆動領域３２０（図４Ｂ参照）との点灯駆動について説明する。 First, the lighting drive of the headlamp drive region 310 (see FIG. 4A) and the DRL drive region 320 (see FIG. 4B) will be described.

図４Ａは、車両用光学装置１００の前照灯駆動領域３１０により前照灯駆動させた例を示している。
この場合、光照射部３００の左右端部における前照灯駆動領域３１０に配置された区画部１３０から、前照灯用の光を照射させる。なお、予め前照灯駆動領域３１０が設定されているため、この領域に光を供給する発光素子２３０自体の輝度を前照灯として最適の輝度に設定する。あるいは、前照灯として駆動させる際に、前照灯として最適の電力を供給するようにしてもよい。 FIG. 4A shows an example in which headlights are driven by the headlight driving area 310 of the vehicle optical device 100 .
In this case, the light for the headlamp is emitted from the division section 130 arranged in the headlamp drive area 310 at the left and right ends of the light emitting section 300 . Since the headlamp drive area 310 is set in advance, the brightness of the light emitting element 230 itself that supplies light to this area is set to the optimum brightness for the headlamp. Alternatively, when driving as a headlamp, the optimum power for the headlamp may be supplied.

次に、図４Ｂは、車両用光学装置１００のＤＲＬ駆動領域３２０の区画部１３０からデイタイムランニングライトに最適の輝度で駆動させた例を示している。
このＤＲＬ駆動領域３２０は、光照射部３００の左右端部において前照灯駆動領域３１０の上側に設定された領域であり、この領域内の区画部１３０から、予めデイタイムランニングライト（以下、ＤＲＬという）に応じた輝度の光を照射させる。この場合も、予めＤＲＬ駆動領域３２０の区画部１３０に光を供給する発光素子２３０の輝度をＤＲＬとして好適な輝度に設定してもよいし、あるいは、ＤＲＬとして最適の電力を供給するようにしてもよい。なお、前照灯駆動領域３１０やＤＲＬ駆動領域３２０に配置された区画部１３０における照明構造としては、プロジェクタタイプ、リフレクタタイプ、直射タイプのいずれの照明構造としてもよい。 Next, FIG. 4B shows an example in which daytime running lights are driven with optimum brightness from the division part 130 of the DRL driving region 320 of the vehicle optical device 100 .
The DRL drive region 320 is a region set above the headlamp drive region 310 at the left and right ends of the light irradiation unit 300. A daytime running light (hereinafter referred to as DRL ) is emitted. In this case as well, the luminance of the light emitting element 230 that supplies light to the partitioning portion 130 of the DRL driving region 320 may be set in advance to a luminance suitable for the DRL, or the optimum power may be supplied as the DRL. good too. The illumination structure in the partitions 130 arranged in the headlamp drive region 310 and the DRL drive region 320 may be any of a projector type, a reflector type, and a direct type.

さらに、ＤＲＬ駆動領域３２０として示した領域を、方向指示などを行う領域として使用してもよい。例えば、この場合、図４Ｂに示すＤＲＬ駆動領域３２０おいて、最も高い位置に配置された部位であって、前照灯駆動領域３１０よりも車両外側に光を照射する位置を信号灯の領域とする。また、この場合、発光素子２３０の発光時の色を、黄色、オレンジ色、橙色などの方向指示の際に一般的に用いられる色にするのが好ましい。 Furthermore, the area shown as the DRL drive area 320 may be used as an area for direction indication and the like. For example, in this case, in the DRL drive region 320 shown in FIG. 4B, the position that is located at the highest position and that irradiates light to the outside of the vehicle from the headlight drive region 310 is set as the signal light region. . Also, in this case, it is preferable that the light emitting color of the light emitting element 230 is yellow, orange, or orange, which is generally used for direction indication.

次に、情報表示領域３３０によるメッセージや記号などを用いた情報出力について説明する。
図４Ｃは文字表示による情報出力を行った例を示している。
前述したように、上下方向及び左右方向に複数の区画部１３０を並設していることから、区画部１３０を選択的に発光させることにより、文字や数字などを表示することができる。 Next, information output using messages, symbols, and the like from the information display area 330 will be described.
FIG. 4C shows an example of information output by character display.
As described above, since a plurality of partitions 130 are arranged in parallel in the vertical direction and the horizontal direction, characters, numbers, and the like can be displayed by selectively causing the partitions 130 to emit light.

そこで、本実施の形態１では、車両前面部分の光照射部３００において車幅方向中央位置であって、前照灯駆動領域３１０やＤＲＬ駆動領域３２０よりも上下方向の寸法が大きな広い領域に情報表示領域３３０を設定している。これにより、上下、左右に並ぶ多数の区画部１３０を独立して点消灯させて、文字や記号などを用いた表示が可能である。
図４Ｃでは、文字の表示例として、「ＡＬＥＲＴ」という文字を表示した例を示すが、例えば、「ＥＭＥＲＧＥＮＣＹ」など他の文字によるメッセージを表示してもよい。 Therefore, in the first embodiment, information is provided in a wide area that is located at the center position in the vehicle width direction in the light irradiation unit 300 in the front part of the vehicle and has a larger vertical dimension than the headlight driving area 310 and the DRL driving area 320. A display area 330 is set. Accordingly, it is possible to independently turn on and off a large number of partitions 130 arranged vertically and horizontally to display characters, symbols, and the like.
In FIG. 4C, an example of displaying the characters "ALERT" is shown as an example of displaying characters, but for example, a message using other characters such as "EMERGENCY" may be displayed.

（昼間の表示）
次に、昼間の点灯表示について説明する。
区画部１３０に太陽光が直接入射している場合や、周囲の明るさが明るい場合には、区画部１３０の点灯と消灯との区別がつきにくく、特に、情報表示領域３３０において表示を行っている場合、その視認性が低下するおそれがある。
これに対し、本実施の形態１では、図５に示すように、車両斜め上方からの太陽光に対し、車両前面部分のルーバー１１０が庇となって、区画部１３０に影を作り、レンズ部材２１０の前面２１０ａに直接太陽光が当たるのを抑制することができる。これにより、低輝度の発光でも、区画部１３０において点灯、消灯の違いのコントラストを明確にし、上述の文字出力などの信号表示を明確に行うことができる。
よって、周囲が明るい状況においても、エネルギ（電力）の消費を抑えつつ、視認性に優れる車両用光学装置１００を提供することができる。 (daytime display)
Next, lighting display in the daytime will be described.
When sunlight is directly incident on the division part 130 or when the brightness of the surroundings is bright, it is difficult to distinguish whether the division part 130 is on or off. If there is, there is a risk that its visibility will be reduced.
On the other hand, in the first embodiment, as shown in FIG. 5, the louver 110 in the front part of the vehicle acts as a canopy against the sunlight from obliquely above the vehicle, forming a shadow on the partition part 130, and the lens member The front surface 210a of 210 can be prevented from being exposed to direct sunlight. As a result, even with low-luminance light emission, it is possible to clarify the contrast of the difference between lighting and extinguishing in the division part 130, and to clearly perform the signal display such as the character output described above.
Therefore, it is possible to provide the vehicular optical device 100 that has excellent visibility while suppressing energy (electric power) consumption even in bright surroundings.

また、ドライバ２６０は、昼間であっても、曇天時やトンネル内などのように、暗い環境下にあることをセンサにより検出した場合には、発光素子２３０の発光輝度を低下させる制御を行うのが好ましい。逆に、太陽の位置が低いこと、すなわち、ルーバー１１０による影が十分に得られない状況をセンサにより検出した場合には、発光素子２３０の輝度を上昇させるようにしてもよい。 Even in the daytime, when the sensor detects that the driver 260 is in a dark environment such as when it is cloudy or in a tunnel, the driver 260 performs control to reduce the light emission luminance of the light emitting element 230 . is preferred. Conversely, when the sensor detects that the position of the sun is low, that is, a situation in which the louver 110 cannot provide a sufficient shadow, the brightness of the light emitting element 230 may be increased.

また、複数のルーバー１１０を上下方向に間隔を空けて並設しているため、ルーバー１１０の車両前方への突出量を抑えつつ、太陽光に対して全ての光照射部３００の特に情報表示領域３３０の区画部１３０に影を形成することができる。
すなわち、１枚のルーバーで少なくとも情報表示領域３３０の全面に影を作るには、ルーバーを車両前方に大きく突出させる必要がある。それに対して、実施の形態１では、各区画部１３０の上側にルーバー１１０を設けているため、車両前方への突出量を抑えつつ、光照射部３００の全ての区画部１３０に影を形成し、視認性を確保することができる。 In addition, since a plurality of louvers 110 are arranged side by side at intervals in the vertical direction, the amount of protrusion of the louvers 110 toward the front of the vehicle is suppressed, and all the light irradiation units 300, particularly the information display areas, are exposed to sunlight. A shadow can be formed in the compartment 130 at 330 .
That is, in order to shade at least the entire surface of the information display area 330 with one louver, the louver needs to protrude greatly forward of the vehicle. On the other hand, in Embodiment 1, since the louvers 110 are provided on the upper side of each partition 130, shadows are formed on all partitions 130 of the light irradiation unit 300 while suppressing the amount of protrusion to the front of the vehicle. , visibility can be ensured.

特に、本実施の形態１では、情報表示領域３３０において、点消灯の組み合わせによりメッセージや記号や図形などの表示を行うようにしており、ルーバー１１０により各区画部１３０に影を形成して、点灯状態を明確に表示することが可能である。 In particular, in the first embodiment, in the information display area 330, a message, a symbol, a figure, or the like is displayed by a combination of lighting and extinguishing. It is possible to clearly display the state.

（実施の形態１の効果）
以下に、実施の形態１の車両用光学装置１００の効果を列挙する。

したがって、光照射部３００の区画部１３０では、太陽光の直射がルーバー１１０により遮られ、明暗差によるコントラストの高い見映え（表示）を実現することができる。また、ルーバー１１０により区画部１３０に影を作ることができるため、光照射部３００の昼間の輝度を抑えることができ、消費電力の低下を図ることができる。そして、光照射部３００の全体に１つのルーバーを設ける場合と比較して、ルーバー１１０の突出量を抑えることができる。 (Effect of Embodiment 1)

Therefore, in the division part 130 of the light irradiation part 300, direct sunlight is blocked by the louver 110, and a high-contrast appearance (display) due to the difference in brightness can be realized. In addition, since the louver 110 can cast a shadow on the division part 130, the brightness of the light irradiation part 300 in the daytime can be suppressed, and the power consumption can be reduced. Further, compared to the case where one louver is provided for the entire light irradiation section 300, the amount of protrusion of the louver 110 can be suppressed.

(2) 実施の形態１の車両用光学装置１００は、区画部１３０の点消灯の組み合わせにより一以上の照射パターンで光を照射するよう光照射部３００の点消灯を制御するドライバ２６０を有する。

Therefore, by combining the lighting and extinguishing of a plurality of partitions 130, it is possible to provide the vehicle optical device 100 capable of displaying an irradiation pattern for displaying figures, characters, and the like that serve as signs.

(3) 実施の形態１の車両用光学装置１００では、光照射部３００は、上下方向及び左右方向に複数の区画部１３０に区画され、ドライバ２６０は、複数の光源としての発光素子２３０の点消灯の組み合わせを制御して照射パターンを切り替え可能である。
したがって、多種類の照射パターンによる表示が可能であるとともに、より視認性の高い車両用光学装置１００を提供することができる。 (3) In the vehicle optical device 100 of Embodiment 1, the light irradiation unit 300 is partitioned into a plurality of partitions 130 in the vertical direction and the horizontal direction, and the driver 260 controls the points of the light emitting elements 230 as a plurality of light sources. It is possible to switch the irradiation pattern by controlling the combination of lights off.
Therefore, it is possible to provide the vehicular optical device 100 that enables display with various types of irradiation patterns and has higher visibility.

(4) 実施の形態１の車両用光学装置１００では、各区画部１３０は、それぞれに光源としての発光素子２３０を有し、ドライバ２６０は、発光素子２３０を独立して点消灯及び調光及び／又は調色を制御する。
したがって、発光素子２３０の点消灯及び調光及び／又は調色を制御することにより、多種類の照射パターンが形成可能である。 (4) In the vehicular optical device 100 of Embodiment 1, each partition 130 has the light emitting element 230 as a light source, and the driver 260 independently turns on/off the light emitting element 230, dims the light, and adjusts the light. /or to control toning.
Therefore, various types of irradiation patterns can be formed by controlling the lighting and extinguishing of the light-emitting element 230 and the dimming and/or toning.

(5) 実施の形態１の車両用光学装置１００では、光照射部３００は、ルーバー１１０の下方位置に発光部としてのレンズ部材２１０の前面２１０ａを備え、レンズ部材２１０の前面２１０ａは、ルーバー１１０の先端よりも奥側に配置されている。
したがって、発光部であるレンズ部材２１０の前面２１０ａが太陽光に直射されるのを、より確実に抑制し、上記(1)の低輝度での視認性の確保をより確実に図ることができる。 (5) In the vehicle optical device 100 of Embodiment 1, the light irradiation section 300 has the front surface 210a of the lens member 210 as the light emitting section below the louver 110. The front surface 210a of the lens member 210 It is arranged on the far side from the tip of the
Therefore, it is possible to more reliably prevent the front surface 210a of the lens member 210, which is the light-emitting portion, from being directly exposed to the sunlight, thereby more reliably ensuring the above-mentioned (1) visibility at low luminance.

(6) 実施の形態１の車両用光学装置１００では、光照射部３００は、レンズを介して光を車両前方に照射するレンズ部材２１０を有し、レンズ部材２１０は、ルーバー１１０の下方位置に設けられている。
したがって、個々のレンズ部材２１０の上方にルーバー１１０を配置したため、ルーバー１１０の前後長を短く抑えつつ、区画部１３０への太陽の直射を抑制して視認性を確保できる。
しかも、レンズ部材２１０を有することで、反射面タイプ、導光タイプなど光照射部３００の種類を問わず、レンズ部材２１０の前面２１０ａを発光表示面とすることができ、例えば反射板２５０の反射面のようなルーバー１１０の先端から奥まった位置に発光表示面が配置された場合と比較して、様々な角度から見ても発光表示面がルーバー１１０により遮られる不具合を抑制でき、視認性をより確実に確保できる。 (6) In the vehicle optical device 100 of Embodiment 1, the light irradiation unit 300 has the lens member 210 that irradiates light forward of the vehicle through the lens. is provided.
Therefore, since the louvers 110 are arranged above the individual lens members 210, the front-to-rear length of the louvers 110 can be kept short, and the direct sunlight to the partitions 130 can be suppressed to ensure visibility.
Moreover, by having the lens member 210, the front surface 210a of the lens member 210 can be used as a light-emitting display surface regardless of the type of the light irradiation unit 300, such as a reflective surface type or a light guide type. Compared to the case where the light-emitting display surface is arranged at a position recessed from the tip of the louver 110 like a surface, it is possible to suppress the problem that the light-emitting display surface is blocked by the louver 110 even when viewed from various angles, and visibility is improved. can be secured more securely.

(7) 実施の形態１の車両用光学装置１００では、光照射部３００は、一部が前照灯駆動領域３１０として形成されている。
したがって、複数の区画部１３０により点消灯する光照射部３００が前照灯としても駆動することにより、一体感のあるデザイン性に優れた車両用光学装置１００を提供できる。 (7) In the vehicle optical device 100 of Embodiment 1, the light irradiation section 300 is partly formed as the headlamp drive region 310 .
Therefore, by driving the light irradiation unit 300 that is turned on and off by the plurality of division units 130 also as a headlamp, it is possible to provide the vehicle optical device 100 that has a sense of unity and is excellent in design.

(8) 実施の形態１の車両用光学装置１００では、光照射部３００は、前照灯駆動領域３１０よりも車両外側位置で光を照射する位置に信号灯領域が形成されている。
したがって、信号灯領域として視認性に優れ、かつ、一体感のあるデザイン性に優れた車両用光学装置１００を提供できる。 (8) In the vehicle optical device 100 of Embodiment 1, the light irradiation section 300 has the signal lamp region formed at a position where the light is emitted outside the vehicle from the headlamp drive region 310 .

Therefore, it is possible to provide the vehicle optical device 100 having a novel appearance with a sense of unity by the light irradiation unit 300 and the louver 110 .

(10) 実施の形態１の車両用光学装置１００は、レンズ部材２１０と遮光部材としてのルーバー１１０とを、樹脂により一体的に形成した。
