Description

本発明は、複数の光源セグメントを車幅方向に配列してなる車両の走行用前照灯に関するものである。 The present invention relates to a traveling headlight of a vehicle in which a plurality of light source segments are arranged in the vehicle width direction.

近時、夜間に車両の前方にある交通上の障害物を適切に確認でき、かつ照射光線が対向車や先行車の交通を妨げないような、配光可変型前照灯システムが開発されている。配光可変型前照灯システムは、車載のカメラで撮影した画像を解析して対向車や先行車を検出し、当該対向車または先行車の存在する領域以外の領域に向けて照明光を正射する状態を維持しながら、当該対向車または先行車の存在する領域に限って照明光を照射しないようにするものである。配光可変型前照灯システムにより、対向車または先行車の搭乗者を眩惑させずに走行用前照灯(ハイビーム)を使用して安全に夜間走行を行うことができる。 Recently, a variable light distribution type headlight system has been developed so that traffic obstacles in front of the vehicle can be properly confirmed at night and the irradiation light does not obstruct the traffic of oncoming vehicles and preceding vehicles. There is. The variable light distribution type headlight system analyzes the image taken by the in-vehicle camera to detect the oncoming vehicle and the preceding vehicle, and directs the illumination light to an area other than the area where the oncoming vehicle or the preceding vehicle exists. While maintaining the shining state, the illumination light is not radiated only in the area where the oncoming vehicle or the preceding vehicle exists. The variable light distribution type headlight system enables safe night driving using the driving headlight (high beam) without dazzling the passengers of the oncoming vehicle or the preceding vehicle.

前照灯の配光パターンを変化させるための仕組みとして、例えば特許文献1は、複数の光源セグメントを構成要素とし、対向車の出現を認識したときに、その対向車を指向する光源セグメントを消灯し、または当該光源セグメントから放射する光束の量を平常よりも減少させることで、対向車の搭乗者の眩惑を抑止する配光可変型前照灯システムを開示している。 As a mechanism for changing the light distribution pattern of the headlight, for example, Patent Document 1 has a plurality of light source segments as constituent elements, and when recognizing the appearance of an oncoming vehicle, the light source segment pointing to the oncoming vehicle is turned off. However, it discloses a variable light distribution type headlight system that suppresses dazzling of passengers of an oncoming vehicle by reducing the amount of light emitted from the light source segment from the normal level.

特開2018−103904号公報(請求項1)JP-A-2018-103904 (Claim 1)

ところで、走行用前照灯を上下方向に薄くすることによって意匠性の向上を図ることがあり、特許文献1のような複数の光源セグメントで構成した走行用前照灯を薄くするための手段として、その複数の光源セグメントを車幅方向に配列することが考えられる。 By the way, the design may be improved by thinning the traveling headlight in the vertical direction, and as a means for thinning the traveling headlight composed of a plurality of light source segments as in Patent Document 1. , It is conceivable to arrange the plurality of light source segments in the vehicle width direction.

しかしながら、複数の光源セグメントを単に車幅方向に配列すると、走行用前照灯の幅が大きくなり、却って意匠性を損なうおそれがある。 However, if a plurality of light source segments are simply arranged in the vehicle width direction, the width of the traveling headlight becomes large, which may rather impair the design.

本発明は、複数の光源セグメントを車幅方向に配列しつつ、その幅を抑えることのできる車両の走行用前照灯の提供を目的とする。 An object of the present invention is to provide a headlight for traveling of a vehicle capable of suppressing the width of a plurality of light source segments while arranging them in the vehicle width direction.

上記目的を達成するために、本発明に係る車両の走行用前照灯は、複数の光源セグメントを車幅方向に配列したものであり、複数の光源セグメントのうちの少なくとも一つ以上の光源セグメントについて、車幅方向に沿って内側に隣接する光源セグメントよりも、その光軸を外側に傾斜する方向に設定すると共に、その後端における車幅方向の端部が前記内側に隣接する光源セグメントの後端と車幅方向において互いに重なるまで光軸に沿って後退する位置に設けたものである。 In order to achieve the above object, the vehicle traveling headlight according to the present invention has a plurality of light source segments arranged in the vehicle width direction, and at least one or more light source segments among the plurality of light source segments. Is set so that its optical axis is inclined outward from the light source segment adjacent to the inside along the vehicle width direction, and the end portion in the vehicle width direction at the rear end is behind the light source segment adjacent to the inside. It is provided at a position where it retracts along the optical axis until it overlaps with each other in the direction of the end and the width of the vehicle.

以上のとおり、本発明によると、外側の光源セグメントを内側に隣接する光源セグメントよりも、光軸を外側に傾斜させつつ、その光軸に沿って後退させるので、照射する光を遮ることなく、車両中心線と平行な方向において、外側の光源セグメントの内端部分を内側に隣接する光源セグメントの後方に位置させることができる。 As described above, according to the present invention, the outer light source segment is tilted outward with respect to the light source segment adjacent to the inner side, and is retracted along the optical axis. In a direction parallel to the vehicle center line, the inner end portion of the outer light source segment can be located behind the inner adjacent light source segment.

これにより、照射する光を遮ることなく、隣接する光源セグメントを車両の正面視で重ねることができ、複数の光源セグメントを車幅方向に配列した車両の走行用前照灯の幅を抑えることができる。 As a result, adjacent light source segments can be overlapped with each other in the front view of the vehicle without blocking the emitted light, and the width of the traveling headlight of the vehicle in which a plurality of light source segments are arranged in the vehicle width direction can be suppressed. can.

以下、本発明に係る車両の走行用前照灯を実施するための形態について、図面を用いて説明する。 Hereinafter, a mode for carrying out the traveling headlight of the vehicle according to the present invention will be described with reference to the drawings.

図1に示すように、走行用前照灯1は、夜間に車両の前方を照射することによって交通上の障害物を適切に確認するためのものであり、車両2の前端部における左右の側部に設けられる。 As shown in FIG. 1, the traveling headlight 1 is for appropriately confirming an obstacle in traffic by illuminating the front of the vehicle at night, and is on the left and right sides of the front end of the vehicle 2. It is provided in the part.

図2〜図4に示すように、走行用前照灯1は、複数の光源セグメント3a、3b、3c、3dを車幅方向に配列した構造とされ、その光源セグメント3a、3b、3c、3dは、照明光4を放射する発光ダイオードなどの照明光源5と、照明光源5から放射される照明光4を車両2の前方に向ける凹面状のリフレクタ6とから構成される。 As shown in FIGS. 2 to 4, the traveling headlight 1 has a structure in which a plurality of light source segments 3a, 3b, 3c, and 3d are arranged in the vehicle width direction, and the light source segments 3a, 3b, 3c, and 3d are arranged in the vehicle width direction. Consists of an illumination light source 5 such as a light emitting diode that emits illumination light 4, and a concave reflector 6 that directs the illumination light 4 emitted from the illumination light source 5 to the front of the vehicle 2.

図3に示すように、照明光源5は、水平に配置された基板7の下面に設けられて下向きの照明光4を出射し、この下向きの照明光4がリフレクタ6の前面で反射されることにより、車両2の前方に光を照射するようになっている。 As shown in FIG. 3, the illumination light source 5 is provided on the lower surface of the horizontally arranged substrate 7 to emit downward illumination light 4, and the downward illumination light 4 is reflected by the front surface of the reflector 6. As a result, the front of the vehicle 2 is irradiated with light.

図4に示すように、各光源セグメント3a、3b、3c、3dは、その照明光源5が出射した照明光4を凹面状のリフレクタ6が広げて反射することにより、それぞれが個別の照射範囲8a、8b、8c、8dを照射する。光源セグメント3a、3b、3c、3dの光軸9a、9b、9c、9dは、車幅方向に沿って外側のものほど、外側に傾斜する方向に設定され、互いに隣接する照射範囲8a、8b、8c、8dの側部を重ねつつ、車両の前方から斜め側方に至る範囲を照射する。 As shown in FIG. 4, each of the light source segments 3a, 3b, 3c, and 3d has an individual irradiation range 8a due to the concave reflector 6 spreading and reflecting the illumination light 4 emitted by the illumination light source 5. , 8b, 8c, 8d are irradiated. The optical axes 9a, 9b, 9c, 9d of the light source segments 3a, 3b, 3c, and 3d are set so as to incline outward toward the outer side along the vehicle width direction, and the irradiation ranges 8a, 8b, which are adjacent to each other, are set. While overlapping the sides of 8c and 8d, the area from the front of the vehicle to the diagonal side is irradiated.

この光源セグメント3a、3b、3c、3dは、外側のものほど光軸9a、9b、9c、9dが外側に傾斜することに加えて、外側のものほど光軸9a、9b、9c、9dに沿って後退する位置に設けられている。 In the light source segments 3a, 3b, 3c, and 3d, the outer ones have the optical axes 9a, 9b, 9c, and 9d inclined outward, and the outer ones are along the optical axes 9a, 9b, 9c, and 9d. It is provided in a position to retreat.

これにより、光源セグメント3a、3b、3c、3dの複数のリフレクタ6が平面視で略階段状に並べて形成されつつ、その端部が正面視で互いに重ねられ、その総幅を小さくして、走行用前照灯1の幅を小さくすることができるようになっている。具体的に説明すると、例えば、一番外側の光源セグメント3aは、内側に隣接する光源セグメント3bによって照射範囲8aを遮られることなく、内端部分10を光源セグメント3bの後方に位置させ、正面視で光源セグメント3bに重ねている。 As a result, a plurality of reflectors 6 of the light source segments 3a, 3b, 3c, and 3d are formed side by side in a substantially stepped manner in a plan view, and their ends are overlapped with each other in a front view to reduce the total width and travel. The width of the headlight 1 can be reduced. Specifically, for example, in the outermost light source segment 3a, the inner end portion 10 is positioned behind the light source segment 3b without being blocked by the light source segment 3b adjacent to the inner side, and the front view is performed. Overlaid on the light source segment 3b.

光源セグメント3a、3b、3c、3dの各照明光源5は、それぞれ独立して点灯及び消灯を可能とされ、例えば車載カメラの画像の解析によって対向車や先行車を検出した際、その対向車や先行車の存在する領域に照明光4を照射することなく、それ以外の領域に向けた照明光4のみを照射することができる。 Each of the illumination light sources 5 of the light source segments 3a, 3b, 3c, and 3d can be turned on and off independently. For example, when an oncoming vehicle or a preceding vehicle is detected by analyzing an image of an in-vehicle camera, the oncoming vehicle or It is possible to irradiate only the illumination light 4 directed to the other regions without irradiating the region where the preceding vehicle exists.

さらに、例えば、照明光源5に印加する平均の電流量をFET(Field Effect Transistor)その他の半導体スイッチング素子を介して増減させるPWM(Pulse Width Modulation)制御により、照明光源5から放たれる光束の量を制御するようにしてもよい。これにより、対向車や先行車の出現を認識した際、その対向車や先行車を指向する光源セグメント3a、3b、3c、3dから放射する光束の量を平常よりも減少させて、対向車や先行車の搭乗者の眩惑を抑止することができる。 Further, for example, the amount of light beam emitted from the illumination light source 5 by PWM (Pulse Width Modulation) control that increases or decreases the average amount of current applied to the illumination light source 5 via a FET (Field Effect Transistor) or other semiconductor switching element. May be controlled. As a result, when the appearance of an oncoming vehicle or a preceding vehicle is recognized, the amount of light flux radiated from the light source segments 3a, 3b, 3c, and 3d that direct the oncoming vehicle or the preceding vehicle is reduced from the normal level, and the oncoming vehicle or the preceding vehicle It is possible to suppress the dazzling of the passengers of the preceding vehicle.

なお、本発明は、上記の実施の形態に限定されるものではなく、本発明の範囲内において、適宜変更を加えることができる。例えば、光源セグメントは、車幅方向に沿って外側のものほど、その光軸を外側に傾斜する方向に設定するだけでなく、少なくとも一つ以上の光源セグメントについて、車幅方向に沿って内側に隣接する光源セグメントよりも、その光軸を外側に傾斜する方向に設定すると共に、光軸に沿って後退する位置に設けていればよい。 The present invention is not limited to the above-described embodiment, and modifications can be made as appropriate within the scope of the present invention. For example, the light source segment that is outward along the vehicle width direction is not only set so that its optical axis is inclined outward, but also at least one or more light source segments are set inward along the vehicle width direction. The optical axis may be set in a direction in which the optical axis is inclined outward from the adjacent light source segment, and may be provided at a position where the optical axis recedes along the optical axis.
