Description

本発明はヘッドライトに関するものであり、詳細には、点灯中にはヘッドライトの外周に略リング状の光を生じるようにし、点灯時の美観の一層の向上を図ると共に、ヘッドライトの先端部分を、照射方向以外の方向にも発光させることで、視認性の向上を一層に図れるものとしたヘッドライトの構成に係るものである。   The present invention relates to a headlight, and more specifically, a substantially ring-shaped light is generated on the outer periphery of the headlight during lighting, thereby further improving the aesthetic appearance during lighting, and at the tip of the headlight. The light is emitted also in directions other than the irradiation direction, whereby the visibility can be further improved and the headlight is thus configured.

従来の、夜間にヘッドライト90の周縁にリング状に光る装飾用ランプを設けるときの構成の例を示すものが図4であり、例えば回転放物面など放物面系の反射面を用いて構成された第一のライト91の反射面92内にはポジションランプ用のソケット93が設けられている。   FIG. 4 shows an example of a conventional configuration for providing a decorative lamp that shines in a ring shape on the periphery of the headlight 90 at night. For example, a parabolic reflecting surface such as a rotating paraboloid is used. A socket 93 for a position lamp is provided in the reflecting surface 92 of the constructed first light 91.

同時に、前記反射面92の外縁には、前記ソケット93に挿着された前記ポジションランプからの光を車両の前方に向けて反射するポジション用リフレクタ94が、一体、若しくは、分割した状態で設けられている。よって、薄暮時などとなり、前記ポジションランプを点灯させれば、前記ポジション用リフレクタ94により前記反射面92の外縁が光輝するものとなる。尚、図中に符号80で示すものはプロジェクタ型などとした、第二のライトである。
特開2005−190890号公報
At the same time, on the outer edge of the reflecting surface 92, a position reflector 94 for reflecting light from the position lamp inserted in the socket 93 toward the front of the vehicle is provided in an integrated or divided state. ing. Therefore, when the position lamp is turned on, for example, at dusk, the outer edge of the reflecting surface 92 is brilliant by the position reflector 94. Incidentally, what is indicated by reference numeral 80 in the figure is a second light of a projector type or the like.
JP 2005-190890 A

しかしながら、上記した従来の装飾用ランプにおいては、確かに薄暮時に点灯を行ったときには、第一のライト91の周縁がリング状に光るものとなり、歩行者、対向車に対して大きな装飾的効果が得られるものとなるが、薄暮時を過ぎ第一のライト91を点灯した場合には、第一のライト91用の桁違いに明るい電球からの光により、実質的には点灯していることが判然としなくなり、期待する効果が得られないものとなるという問題点を生じている。   However, in the above-described conventional decorative lamp, when the lighting is performed at dusk, the periphery of the first light 91 shines in a ring shape, which has a large decorative effect on pedestrians and oncoming vehicles. Although it will be obtained, when the first light 91 is turned on after the twilight time, the light from the light bulb for the first light 91 may be substantially turned on by light. There is a problem that it becomes unclear and the expected effect cannot be obtained.

但し、本来の装飾性の向上という観点からすれば、ヘッドライト90を点灯した際にも、ヘッドライト90の外周に明確に前記装飾用ランプが点灯していることが見えていることが、より好ましいものであることは、言うまでもなく、よって、本発明は、ヘッドライト90の点灯時にも、存在が明確な装飾用ランプの構成を提供するものである。   However, from the viewpoint of improving the original decorativeness, it can be seen that even when the headlight 90 is turned on, the decorative lamp is clearly lit on the outer periphery of the headlight 90. Needless to say, the present invention provides a configuration of a decorative lamp whose presence is clear even when the headlight 90 is turned on.

本発明は、上記した従来の課題を解決するための具体的手段として、ヘッドライトに組み込まれたリフレクターの発光部以外の場所をカバーする意匠部品であるエクステンションの一部として、リフレクターの発光部の外周近傍位置に、リング状、ブロック状とした光を透過する装飾レンズを嵌め込み、その装飾レンズを光らせるための専用反射面が、ヘッドライトの光源付近を焦点とする回転放物面、或いは、光源付近を第一焦点、装飾レンズ発光部付近を第二焦点とする回転楕円面、若しくは、前記回転放物面と前記回転楕円面の組合わせで形成された複数の反射面からなり、前記リフレクターの発光面の最外端の一部に設置されていることを特徴とするヘッドライトを提供することで課題を解決するものである。   As a specific means for solving the above-described conventional problems, the present invention provides a light emitting part of a reflector as a part of an extension that is a design part that covers a place other than the light emitting part of a reflector incorporated in a headlight. A ring-shaped or block-shaped decorative lens that transmits light is inserted in the vicinity of the outer periphery, and a dedicated reflecting surface for illuminating the decorative lens is a paraboloid or light source that focuses on the vicinity of the light source of the headlight. A spheroid having a first focal point in the vicinity and a second focal point in the vicinity of the decorative lens light emitting portion, or a plurality of reflecting surfaces formed by a combination of the parabolic surface and the spheroid surface, The problem is solved by providing a headlight characterized by being installed at a part of the outermost end of the light emitting surface.

本発明により、装飾レンズを光輝させるための光源をヘッドライトと共用させたことで光量的にも充分な光量が得られるものとなり、また、ヘッドライト用のリフレクタの最外周部に装飾レンズに光を供給する専用反射面を形成したことで、前記装飾レンズに対して充分な光を供給できるものとして、ヘッドライトの点灯時にも、前記装飾レンズからの光が見え難くなることをなくして、ヘッドライトの点灯時、不点灯に関わらず充分な装飾効果を発揮できるものとする。   According to the present invention, a light source for shining the decorative lens is shared with the headlight, so that a sufficient amount of light can be obtained. In addition, the decorative lens has a light beam on the outermost peripheral portion of the headlight reflector. By forming a dedicated reflecting surface for supplying the head, it is possible to supply a sufficient amount of light to the decorative lens, so that the light from the decorative lens is not easily seen even when the headlight is turned on. When the light is turned on, a sufficient decoration effect can be exhibited regardless of the non-lighting.

また、専用反射面をヘッドライト用のリフレクタの最外周部に設けたことで、前記専用反射鏡は、例えば、光源を焦点とする放物系反射面、或いは、光源を第一焦点とし装飾レンズの近傍を第二焦点とする楕円系反射面など、設計に自由度を与え、これにより、前記装飾レンズから放射される光の見え方にも様々なバリエーションが与えられるものとして、装飾効果を一層にバリエーションを与えられるものとする。   In addition, by providing a dedicated reflecting surface on the outermost peripheral part of the headlight reflector, the dedicated reflecting mirror is, for example, a parabolic reflecting surface having a light source as a focal point, or a decorative lens having a light source as a first focus. As an elliptical reflecting surface with a second focal point in the vicinity of the lens, it gives a degree of freedom in design, thereby giving various variations in the way the light emitted from the decorative lens is seen. Variations shall be given.

つぎに、本発明を図に示す実施形態に基づいて詳細に説明する。図1に示しものは、本発明に係るヘッドライト1の第1実施形態を示す断面図である。   Below, this invention is demonstrated in detail based on embodiment shown in a figure. FIG. 1 is a cross-sectional view showing a first embodiment of a headlight 1 according to the present invention.

この第1実施形態では、ヘッドライト1のリフレクター1aの主反射面2には回転放物面など放物面系反射面を採用し、走行ビーム配光を得るときの例であり、よって、例えば、ハロゲン電球のフィラメントなど光源3は、前記主反射面2の焦点の位置に配置され、前記光源3から主反射面2に当接する光は、光軸Xと平行光として反射されるものとなり、車両の正面遠方を照射するものとなる。   In the first embodiment, the main reflecting surface 2 of the reflector 1a of the headlight 1 is a parabolic reflecting surface such as a rotating paraboloid and is an example of obtaining a traveling beam light distribution. The light source 3 such as a filament of a halogen bulb is disposed at the focal position of the main reflecting surface 2, and the light that comes into contact with the main reflecting surface 2 from the light source 3 is reflected as parallel light with the optical axis X, It will irradiate far away from the front of the vehicle.

そして、前記主反射面2の最外端には前記光源3からの光を反射する専用反射面4が設けられており、この第一実施形態では、前記専用反射面4にも、前記光源3を焦点とする放物面系反射面が採用されている。(以下、放物面系反射面で形成した専用反射面を放物系専用反射面4pと称する)   And the exclusive reflective surface 4 which reflects the light from the said light source 3 is provided in the outermost end of the said main reflective surface 2, In this 1st embodiment, the said light source 3 is also in the said exclusive reflective surface 4. A paraboloidal reflecting surface with a focal point of is adopted. (Hereinafter, the dedicated reflecting surface formed by the parabolic reflecting surface is referred to as a parabolic reflecting surface 4p.)

また、前記放物系専用反射面4pも光軸を主反射面2の光軸Xと同一として形成されているので、反射光も主反射面2と平行方向として反射が行われる。即ち、前記放物系専用反射面4pが反射する光は、主反射面2が反射する光の外側に平行な略リング状の光として存在するものとなる。   Further, since the parabolic dedicated reflecting surface 4p is also formed with the same optical axis as the optical axis X of the main reflecting surface 2, the reflected light is also reflected in the direction parallel to the main reflecting surface 2. That is, the light reflected by the parabolic dedicated reflection surface 4p exists as a substantially ring-shaped light parallel to the outside of the light reflected by the main reflection surface 2.

ここで、前記主反射面2には、光軸Xを調整可能とするエーミング装置(図示せず)が設けられ、ヘッドライト1を車両(図示せず)に取付けたときに、前記光軸Xが車両の軸と一致していないときには、主反射面2の光軸Xを調整し、即ち、主反射面2の向かう方向を車両に一致させるものとされている。   Here, the main reflecting surface 2 is provided with an aiming device (not shown) that can adjust the optical axis X, and when the headlight 1 is attached to a vehicle (not shown), the optical axis X Is not coincident with the vehicle axis, the optical axis X of the main reflecting surface 2 is adjusted, that is, the direction of the main reflecting surface 2 is made coincident with the vehicle.

よって、前記主反射面2の光軸Xの調整を行うときには、主反射面の全体が向きが移動するものとなるので、例えば、前記主反射面2の先端の端面、或いは、裏面などが外部から見えることのないように、主反射面2の外径には先端を覆うようにエクステンション5が設けられている。   Therefore, when the optical axis X of the main reflecting surface 2 is adjusted, the direction of the entire main reflecting surface is moved. For example, the end surface or the back surface of the main reflecting surface 2 is externally attached. An extension 5 is provided on the outer diameter of the main reflecting surface 2 so as to cover the tip.

本発明では、前記エクステンション5を、不透明部材5aと光透過性部材5bとの複合構造、或いは、光透過性部材5bのみで形成するなどして、前記放物系専用反射面4pから反射ししてくる光を前記エクステンション5に達するものとさせ、前記光透過性部材5bの部分を透過させて前記エクステンション5も光輝しているように観視させるものとしている。よって、前記光透過性部材5bの部分は装飾レンズの作用を奏するものとなる。   In the present invention, the extension 5 is reflected from the parabolic dedicated reflective surface 4p by, for example, forming a composite structure of the opaque member 5a and the light transmissive member 5b or only the light transmissive member 5b. The incoming light reaches the extension 5 and is transmitted through the light transmissive member 5b so that the extension 5 is also viewed as shining. Therefore, the portion of the light transmissive member 5b functions as a decorative lens.

尚、上記したエーミング装置などによる前記主反射面2の調整量を考慮すれば、前記放物系専用反射面4pの幅は20mm以下で充分にエクステンション5を照明することが可能であり、また、前記放物系専用反射面4pがこの程度の幅であれば、主反射面2に与える光量減少などの影響も無視できる範囲であることが確認されている。   In consideration of the adjustment amount of the main reflecting surface 2 by the above-described aiming device or the like, the parabolic dedicated reflecting surface 4p can sufficiently illuminate the extension 5 with a width of 20 mm or less, and It has been confirmed that when the parabolic dedicated reflecting surface 4p has such a width, the influence of a reduction in the amount of light given to the main reflecting surface 2 can be ignored.

ここで、上記にも説明したように、前記エクステンション5に期待する機能は、前記主反射面2の先端の端面、或いは、裏面などが外部から見えないようにするものであるので、エクステンション5を光透過性部材5bのみで形成する場合であっても、例えば、梨地仕上、微細なレンズカットなどにより透明性をなくす光透過拡散処理を行い、上記した主反射面2の先端の端面の存在、形状などがあからさまに観視側から認識されないようにしておく。   Here, as described above, the expected function of the extension 5 is to prevent the end surface or the back surface of the main reflecting surface 2 from being seen from the outside. Even in the case of forming with only the light transmissive member 5b, for example, the presence of the end face at the front end of the main reflecting surface 2 by performing a light transmissive diffusion process that eliminates transparency by a satin finish, a fine lens cut, etc. Make sure that the shape is not clearly recognized by the viewer.

尚、上記の説明のように形成した場合、エクステンション5は、従来のポジション用光源6で照明が行われるものではなく、ヘッドライト1の光源3により照明されるものとなるので、必要であれば、主反射面2内にポジション用光源6が突出するように取付けられるようにしておき、ポジションライトが必要なときには、このポジション用光源6を点灯させる。   When formed as described above, the extension 5 is not illuminated by the conventional position light source 6, but is illuminated by the light source 3 of the headlight 1. The position light source 6 is mounted so as to protrude into the main reflecting surface 2, and when the position light is necessary, the position light source 6 is turned on.

図2は以上に説明したようにして形成されたはリフレクター1aを照射方向側から見たときの構成を示す図であり、通常の主反射面2の形状に対して、前記放物系専用反射面4pの部分を1段多く形成すればよいものであり、このときには逆テーパーの部分も生じることもなく、金属のプレス成形、樹脂の金型成型の何れの場合も特に生産が複雑化することはない。   FIG. 2 is a view showing a configuration of the reflector 1a formed as described above when viewed from the irradiation direction side, and the parabolic system-specific reflection with respect to the shape of the normal main reflection surface 2. FIG. It is only necessary to form the surface 4p part by one step. At this time, no reverse taper part is generated, and the production is particularly complicated both in the case of metal press molding and resin mold molding. There is no.

以上の説明は、専用反射面4を放物系、即ち、放物系専用反射面4pとして形成したときの例で説明したが、本発明では、前記放物系専用反射面ではなく、回転楕円面など楕円系としても形成することが可能である。   The above description has been made with an example in which the dedicated reflecting surface 4 is formed as a parabolic system, that is, a parabolic dedicated reflecting surface 4p. However, in the present invention, a rotating ellipse is used instead of the parabolic dedicated reflecting surface. It can also be formed as an elliptical system such as a surface.

図3は、専用反射面4を楕円系専用反射面4oとして形成したときの断面図であり、このときには、前記楕円系専用反射面4oを、第一焦点f1を光源3に有し、第二焦点f2を前記エクステンション5の近傍に有する、回転楕円などの楕円系反射面で形成している。   FIG. 3 is a cross-sectional view when the dedicated reflective surface 4 is formed as an elliptical dedicated reflective surface 4o. In this case, the elliptical dedicated reflective surface 4o has the first focal point f1 in the light source 3, and the second The focal point f2 is formed in the vicinity of the extension 5 by an elliptical reflecting surface such as a spheroid.

よって、この実施例2では、前記楕円系専用反射面4oで反射した後には、再度、集束するものとなり、前記エクステンション5近傍、特に、第二焦点f2近傍における輝度を高くすることが可能となる。よって、エクステンション5の光透過性部材5b(装飾レンズ)に施すレンズカットなどに工夫を凝らすことで、より明るい装飾効果が得られるものとなる。   Therefore, in the second embodiment, after being reflected by the ellipsoidal dedicated reflecting surface 4o, the light is focused again, and the luminance in the vicinity of the extension 5, particularly in the vicinity of the second focal point f2, can be increased. . Therefore, a brighter decorative effect can be obtained by devising a lens cut or the like applied to the light transmissive member 5b (decorative lens) of the extension 5.

以上に説明したように、本発明によりヘッドライト1の光源3からの光と専用反射面4とを利用し、エクステンション5の光透過性部材5bで形成された部分も光るようにしたことで、ヘッドライトの正面形状に沿う形状とされているエクステンション5も夜間は光源3からの充分な光量で明るく光り、明確に見えるものとなって装飾性が増すものとなり、美感の向上に有効となる。   As described above, by using the light from the light source 3 of the headlight 1 and the dedicated reflecting surface 4 according to the present invention, the portion formed by the light transmissive member 5b of the extension 5 is also illuminated. The extension 5 that has a shape that conforms to the front shape of the headlight also shines brightly with a sufficient amount of light from the light source 3 at night, so that it can be clearly seen and the decorativeness is increased, which is effective in improving the aesthetics.

また、ヘッドライト1のデザインは、車両毎に異なるものとなっているので、本発明により同一構成でエクステンション5を光輝させるときにも、その印象はヘッドライト5のデザインに左右される度合いが強いものとなるので、車両毎に異なる印象のものとすることができ、汎用性も広いものとすることができる。   In addition, since the design of the headlight 1 is different for each vehicle, even when the extension 5 is brilliant with the same configuration according to the present invention, the impression is strongly influenced by the design of the headlight 5. Therefore, the vehicle can have a different impression for each vehicle, and the versatility can be widened.
