【従来の技術】[Prior art]

従来のこの種の車両用照明灯具90の構成の例を示すものが図3であり、低く 広くの自動車デザインの傾向に従い車両用照明灯具90の形状も垂直方向の高さ が狭められ、これにより反射鏡91も上下端が切り取られて枠部91aを設けた ものが採用されることが通常となっている。 FIG. 3 shows an example of a configuration of a conventional vehicle lighting device 90 of this type, and the shape of the vehicle lighting device 90 is also narrowed in the vertical direction in accordance with the tendency of low and wide vehicle design. It is usual that the reflecting mirror 91 is also provided with a frame portion 91a by cutting the upper and lower ends.

【考案が解決しようとする課題】[Problems to be solved by the device]

しかしながら、前記した従来の車両用照明灯具90においては、電球92から の光の前記枠部91aに反射した反射光、特に下側の枠部91aからの反射光が 上向きの光となり、対向車に対する眩惑光となる問題点を生じ、この点の解決が 課題とされるものとなっていた。尚、前記電球92に、この電球92からの光が 枠部91aに達することを防止するフードを設ける手段も前記眩惑光の防止手段 として採用されているが、この場合には前記したフード及び取付手段などにより 本来の照射光が減少するなど新たな問題点を生ずるものとなり、本質的な解決手 段とは成らないものであった。 However, in the above-described conventional vehicle lighting device 90, the reflected light of the light from the electric bulb 92 reflected on the frame 91a, especially the reflected light from the lower frame 91a, becomes upward light, which is against the oncoming vehicle. There was a problem of becoming dazzling light, and the solution to this problem became an issue. Incidentally, a means for providing the light bulb 92 with a hood for preventing the light from the light bulb 92 from reaching the frame portion 91a is also adopted as the dazzling light preventing means. This means that new problems such as the reduction of the original irradiation light will occur due to the means, and it will not be an essential solution.

【実施例】【Example】

つぎに、本考案を図に示す実施例に基づいて詳細に説明する。 図1に符号1で示すものは本考案に係る車両用照明灯具であり、この車両用照 明灯具1には枠部3を有する反射鏡2が採用され、電球4からの光の前記枠部3 での反射、特に下側の枠部3での反射により対向車に対し眩惑光となる上向き光 を生ずるものとなっている点は従来例と同様である。 Next, the present invention will be described in detail based on the embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a vehicle lighting device according to the present invention. The vehicle lighting device 1 includes a reflecting mirror 2 having a frame portion 3 and the frame portion for the light from the light bulb 4. Similar to the conventional example, the reflection at 3 and, in particular, the reflection at the lower frame portion 3 causes upward light, which is dazzling light to the oncoming vehicle.

【0006】 しかしながら、本考案により前記車両用照明灯具1のレンズ5の少なくとも下 側の枠部3からの反射光が透過する位置には視界制御フィルタ6が貼着など適宜 な手段により取付けられるものとされ、該視界制御フィルタ6により前記反射鏡 2からの光はその儘に透過させ、前記枠部3からの光はほぼ完全な拡散光とする ものとされている。However, according to the present invention, the visibility control filter 6 is attached to the position where the reflected light from at least the lower frame portion 3 of the lens 5 of the vehicle lighting device 1 is transmitted by an appropriate means such as sticking. The field-of-view control filter 6 allows the light from the reflecting mirror 2 to pass therethrough, while the light from the frame 3 is almost completely diffused.

【0007】 ここで、前記視界制御フィルタ6について更に詳細に説明を行えば、この視界 制御フィルタ6は商品名「ルミスティ」(住友化学工業株式会社)として市販さ れているものの一方向不透明型(Yタイプ)若しくは両方向不透明型(Zタイプ )と称せられるものであり、これらは何れも正面方向からの光に対しては全くの 透明体として透過させるが、一方向或いは両方向の斜め方向に透過する光に対し てはほぼ完全な拡散体として作用するものであり、従って、本考案においては前 記視界制御フィルタ6は上方に向かう光に対して拡散を行うように前記反射鏡2 に対して略直角となるように方向をセットされている。Here, the visibility control filter 6 will be described in more detail. The visibility control filter 6 is a one-way opaque type commercially available under the trade name “Lumisty” (Sumitomo Chemical Co., Ltd.). It is called Y type) or bidirectional opaque type (Z type), and both of them allow the light from the front direction to be transmitted as a completely transparent body, but transmit in one direction or an oblique direction of both directions. It acts as a nearly perfect diffuser for light, and therefore, in the present invention, the view control filter 6 described above is substantially parallel to the reflecting mirror 2 so as to diffuse upward light. The direction is set to be a right angle.

【0008】 次いで、上記の構成とした本考案の作用及び効果について説明を行えば、前記 視界制御フィルタ6が設けられたことで、路面を照射するための前記反射鏡2か らの反射光は前記視界制御フィルタ6を正面方向の角度から透過するものとなり 、配光特性に何等の影響も受けることのないものとなるが、前記枠部3からの反 射光は前記視界制御フィルタ6を斜め方向の角度から透過するものとなり完全に 拡散され、直進光に比較して到達距離を大幅に減ずるものとなる。Next, the operation and effect of the present invention having the above-mentioned configuration will be described. Since the visibility control filter 6 is provided, the reflected light from the reflecting mirror 2 for illuminating the road surface is Although the light is transmitted through the view control filter 6 from an angle in the front direction, and the light distribution characteristic is not affected at all, the reflected light from the frame 3 causes the view control filter 6 to be obliquely moved. The light will be transmitted from the angle of, and will be completely diffused, and the reaching distance will be greatly reduced compared to the straight light.

【0009】 このことは即ち、同じ量の上向き光を生じているときにも対向車に対する眩惑 の発生の度合いが大幅に減ずるものとなり、その目的を達する。尚、視界制御フ ィルタ6は上記した拡散を生ずる角度に対しては射出、入射の何れの方向からの 光に対しても同じ作用を行うので、一般的に目の位置よりも下方にある車両用照 明灯具1の内部を見せないようにする作用も同時に奏するものとなる。This means that even when the same amount of upward light is generated, the degree of dazzling of an oncoming vehicle is significantly reduced, and the purpose thereof is achieved. The field-of-view control filter 6 has the same function with respect to light from either the exiting or incident direction with respect to the angle causing the above-mentioned diffusion, and therefore, the vehicle is generally below the eye position. At the same time, the function of keeping the inside of the illumination lamp 1 from being seen is also achieved.

【0010】 尚、上記の実施例はレンズ5の少なくとも下側の枠部3からの反射光が透過す る位置に視界制御フィルタ6を貼着した例で説明したが、例えば上記したように 車両用照明灯具1の内部の透視を避けることも目的とする場合にはレンズ5の全 面に貼着しても良いものであり、更には前記視界制御フィルタ6は図2に示すよ うにレンズ5と別体に設けても良いものである。In the above embodiment, the visibility control filter 6 is attached at a position where the reflected light from at least the lower frame portion 3 of the lens 5 is transmitted, but, for example, as described above, For the purpose of avoiding the see-through of the interior of the illumination lamp 1, it may be attached to the entire surface of the lens 5, and the visibility control filter 6 is used as shown in FIG. It may be provided separately from.

【考案の効果】[Effect of device]

以上に説明したように本考案により、車両用照明灯具の少なくとも枠部からの 反射光が透過する部分には水平光は透過させ上向き光は拡散するように透過角度 に対して異なる特性を有する視界制御フィルタを設けた車両用照明灯具とするこ とで、配光特性に何等の影響を与えることなく、上向き光のみを拡散するものと して、この上向き光の到達距離を減衰させて防幻効果を高めるものであり、以て 、この種の車両用灯具の性能向上に極めて優れた効果を奏するものである。 As described above, according to the present invention, a field of view having different characteristics with respect to a transmission angle such that horizontal light is transmitted and upward light is diffused at least in a portion where reflected light from a frame portion of a vehicle lighting fixture is transmitted. By providing a vehicle lighting fixture with a control filter, only the upward light is diffused without any effect on the light distribution characteristics, and the reaching distance of the upward light is attenuated to prevent illusion. This is to enhance the effect and, therefore, has an extremely excellent effect for improving the performance of this type of vehicle lamp.

【0012】 また、上記の作用を利用して所定の方向から観視したときの車両用照明灯具の 内部構造を透視させることをなくし、例えば美観の向上を可能とするなど新たな 効果も奏するものとなる。[0012] Further, by utilizing the above-mentioned operation, it is possible to eliminate a see-through of the internal structure of the vehicular illumination lamp when viewed from a predetermined direction, and to obtain a new effect such as an improvement in aesthetic appearance.
