Description

本考案は車両用の前照灯に関するものであり、詳細にはポジション灯を兼用す る構成とした前照灯に係るものである。 The present invention relates to a vehicle headlight, and more particularly to a headlight configured to also serve as a position light.

従来のこの種の前照灯90の構成の例を示すものが図2であり、この前照灯9 0には例えば回転放物面とされた反射鏡91と、該反射鏡の略焦点の位置にフィ ラメントを配設された電球92とで前照灯としての機能が構成されると共に、前 記反射鏡91の一部には開口部91aが設けられて、この開口部91aからポジ ション用電球93が突出させられているものであり、前記ポジション用電球93 の点灯により前記反射鏡91のほヾ全面が光輝してポジション機能が発揮される ものである。 FIG. 2 shows an example of the configuration of a conventional headlight 90 of this type. In the headlight 90, for example, a reflecting mirror 91 which is a paraboloid of revolution and a substantially focal point of the reflecting mirror are provided. The function as a headlight is constituted by a light bulb 92 having a filament disposed at a position, and an opening 91a is provided in a part of the reflecting mirror 91, and a position is provided from this opening 91a. The light bulb 93 for projection is projected, and when the light bulb 93 for position is turned on, the entire surface of the reflecting mirror 91 shines and the position function is exhibited.

しかしながら、前記した従来の前照灯90のポジション機能においては、前記 反射鏡91に対するポジション用電球93の設けられる位置は光学的には何等の 意味も有しないものであったので、前記ポジション用電球93を点灯したときの 前照灯90から放射される光は拡散光となり、こてにより遠距離からの確認が困 難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。 However, in the position function of the conventional headlamp 90 described above, the position where the position light bulb 93 is provided with respect to the reflecting mirror 91 does not have any optical meaning optically. The light emitted from the headlight 90 when the 93 is turned on becomes diffused light, which causes a problem that it is difficult to check from a long distance due to the trowel, and a solution to this problem becomes an issue.

本考案は前記した従来の課題を解決するための具体的手段として、前照灯用の 反射鏡の一部に開口部を設け、該開口部からポジション用電球を突出させてポジ ション灯を兼用する構成とした前照灯において、前記開口部の周縁の少なくとも 一部には前記反射鏡と同時成形で形成され、前記ポジション用電球からの光を前 記前照灯の照射方向と略同一方向に反射する前記ポジション用電球に略焦点を有 する副反射面が設けられていることを特徴とする前照灯を提供することで、遠方 からの視認を可能なものとして、前記従来の課題を解決するものである。 As a concrete means for solving the above-mentioned conventional problems, the present invention provides an opening in a part of a reflector for a headlight, and a position light bulb is projected from the opening to serve also as a position light. In the headlight configured as described above, at least a part of the peripheral edge of the opening is formed simultaneously with the reflecting mirror, and the light from the position light bulb is directed in substantially the same direction as the irradiation direction of the headlight. By providing a headlight, which is characterized in that the position light bulb that reflects light to the position is provided with a sub-reflecting surface having a substantially focal point, it is possible to view from a distant point, and the conventional problem is solved. It is a solution.

つぎに、本考案を図に示す一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前照灯であり、この前照灯1は例えば 回転放物面とされた反射鏡2と、該反射鏡2の略焦点の位置にフィラメントを配 設された電球3とで前照灯機能が構成され、前記反射鏡2には開口部2aが設け られて、この開口部2aからはポジション用電球4が突出させられている点は従 来例のものと同様である。 Next, the present invention will be described in detail based on an embodiment shown in the drawings. Reference numeral 1 in FIG. 1 denotes a headlamp according to the present invention. The headlamp 1 includes a reflecting mirror 2 having a paraboloid of revolution, for example, and a filament at a position substantially at the focal point of the reflecting mirror 2. It is a conventional point that the headlamp function is constituted by the light bulbs 3 arranged and the reflecting mirror 2 is provided with an opening 2a, and the position light bulb 4 is projected from the opening 2a. Similar to the example.
【0006】 しかしながら、本考案においては更に加えて前記開口部2aの周縁には副反射 面5が設けられるものとなり、この副反射面5は前記ポジション用電球4の略フ ィラメントを焦点とする例えば回転放物面で形成され、その照射方向は前記反射 鏡2と略同一とされている。However, in the present invention, in addition to that, a sub-reflecting surface 5 is provided on the periphery of the opening 2a, and the sub-reflecting surface 5 focuses on the substantially filament of the position light bulb 4, for example. It is formed of a paraboloid of revolution, and its irradiation direction is substantially the same as that of the reflecting mirror 2.
【0007】 以下に前記副反射面5について更に詳細に説明を行えば、この副反射面5は前 記反射鏡2の成形用の金型に追加加工を行うことで同時に成形されるようにした ものであり、よって、例えばアンダーカットとなり前記反射鏡2の成形が不可能 となるような部分には設ける必要はなく、前記開口部2aの周縁の一部であって も良いものである。The sub-reflecting surface 5 will be described in more detail below. The sub-reflecting surface 5 is formed at the same time by additionally processing the molding die of the reflecting mirror 2 described above. Therefore, it is not necessary to provide it in a portion where, for example, an undercut occurs and the molding of the reflecting mirror 2 becomes impossible, and it may be a part of the peripheral edge of the opening 2a.
【0008】 尚、前記副反射面5を形成するに当り、好ましくは前記電球3からの直射光が 前記副反射面5に入射して上向きの反射光を生ずることの無いように形成するこ とがグレヤ光の防止の面から望ましく、よって、前記反射鏡2の下半部に副反射 面5を設けるときには、この副反射面5も下半部を省略するなどの配慮が望まし い。In forming the sub-reflecting surface 5, it is preferable that direct light from the light bulb 3 does not enter the sub-reflecting surface 5 and generate upward reflected light. However, when the sub-reflection surface 5 is provided on the lower half portion of the reflecting mirror 2, it is desirable to consider that the lower half portion of the sub-reflection surface 5 is omitted.
【0009】 次いで、上記の構成とした本考案の作用について説明を行えば、ポジション用 電球4を点灯したときには、このポジション用電球4からの光は一部は従来通り に反射鏡2に反射して光輝させ拡散光となって前照灯1の外部に放射されるもの となるが、前記副反射面5が設けられたことで、この副反射面5に反射する一部 の光は平行光となり前照灯1の照射方向に投射されるものとなり、この平行光と されたことで遠方まで到達されるものとなる。Next, the operation of the present invention having the above-described structure will be described. When the position light bulb 4 is turned on, a part of the light from the position light bulb 4 is reflected by the reflecting mirror 2 in the conventional manner. The diffused light is emitted as a diffused light to the outside of the headlight 1. However, since the sub-reflecting surface 5 is provided, a part of the light reflected by the sub-reflecting surface 5 is a parallel light. Then, the light is projected in the irradiation direction of the headlight 1, and the collimated light reaches a distant place.
【0010】[0010]
以上に説明したように本考案により、開口部の周縁にポジション用電球からの 光を前照灯の照射方向と略同一方向に反射する副反射面を設けたことで、前記ポ ジション用電球からの光を平行光として前記前照灯の照射方向に反射するものと なり、より遠方に到達させて視認性を向上させると云うポジション機能の向上に 優れた効果を奏するものとなる。 As described above, according to the present invention, by providing a sub-reflecting surface on the periphery of the opening for reflecting the light from the position light bulb in substantially the same direction as the irradiation direction of the headlight, Light is reflected as parallel light in the irradiation direction of the headlight, and an excellent effect can be obtained in improving the position function of reaching further away and improving visibility.
【0011】 また、前記副反射鏡を反射鏡と同時成形で形成するものとしたことで、前記副 反射鏡を設けるときにも生産工程に何等の追加工程を発生すること無く実施可能 となり、性能向上がコストアップの要因無く得られるものとなる。Further, since the sub-reflecting mirror and the reflecting mirror are formed at the same time, the sub-reflecting mirror can be formed without any additional step in the production process even when the sub-reflecting mirror is provided, and the performance can be improved. The improvement can be obtained without increasing the cost.
