Description

本発明はヘッドランプに係り、特にバルブからの光を凸型レンズを介して外部へ照射するプロジェクター式ヘッドランプの構造に関する。   The present invention relates to a headlamp, and more particularly to a structure of a projector-type headlamp that irradiates light from a bulb to the outside through a convex lens.

図５は従来の車両の右側の車両用ランプ１００の正面図である。この図に示すように、車両用ランプ１００として、近年、フォグランプ１０１と共にプロジェクター式ヘッドランプ１０２を搭載したものが普及している。   FIG. 5 is a front view of a vehicle lamp 100 on the right side of a conventional vehicle. As shown in this figure, as a vehicle lamp 100, in recent years, a projector type headlamp 102 mounted with a fog lamp 101 has become widespread.

図６は図５のＡ−Ａ線に沿ったプロジェクター式ヘッドランプ１０２の断面図であり、このプロジェクター式ヘッドランプ１０２は、ハウジング１１０とアウターレンズ１２０とで画成される灯室Ｓ’内に、バルブ１３１を搭載したプロジェクターユニット１３０と、このバルブ１３１から距離を置いてバルブ前方に配置された凸型レンズ１４０と、を備えている。   FIG. 6 is a cross-sectional view of the projector type headlamp 102 taken along the line AA in FIG. 5. The projector type headlamp 102 is disposed in the lamp chamber S ′ defined by the housing 110 and the outer lens 120. , A projector unit 130 on which the bulb 131 is mounted, and a convex lens 140 disposed in front of the bulb at a distance from the bulb 131.

凸型レンズ１４０からバルブ１３１までの間には、凸型レンズ１４０の周縁から車両後方側へ傘状に広がった透明部材１５０が配設されている。この透明部材１５０は透明樹脂で成るため、日中には透明部材１５０を介して凸型レンズ１４０の奥部、即ちバルブ周辺領域が光に照らされるため、灯体内を明るくすることができる。
夜間では、バルブ１３１からの光が凸型レンズ１４０を介して車両前方を照らすことに加え、透明部材自体が車両外部から光って見えるようにしている。
このように、図６に示すタイプのプロジェクター式ヘッドランプ１０２では、透明樹脂でなる透明部材１５０を凸型レンズ１４０とバルブ１３１との間に配設することで、点灯時及び非点灯時のヘッドランプの見栄えを向上させている。 Between the convex lens 140 and the bulb 131, a transparent member 150 that spreads in an umbrella shape from the periphery of the convex lens 140 to the vehicle rear side is disposed. Since the transparent member 150 is made of a transparent resin, the interior of the convex lens 140, that is, the bulb peripheral region is illuminated with light through the transparent member 150 during the daytime, so that the lamp body can be brightened.
At night, the light from the bulb 131 illuminates the front of the vehicle via the convex lens 140, and the transparent member itself is seen to shine from the outside of the vehicle.
As described above, in the projector-type headlamp 102 of the type shown in FIG. 6, the transparent member 150 made of transparent resin is disposed between the convex lens 140 and the bulb 131, so that the head is turned on and off. The appearance of the lamp is improved.

しかし、図６に示す従来のプロジェクター式ヘッドランプ１０２では、ヘッドランプの正面から透明部材１５０を介してランプ奥側を覗くと、透明部材１５０の車両後方側に配設したプロジェクターユニット１３０が車両外側から視認され得る。そこで、これを隠すために透明部材１５０の車両後方側に中見えを防止する部材（以下、中見え防止部材と呼称する）１６０を配置しているが、このような中見え防止部材１６０を、前述のランプ構成部品とは別個に製造したのでは、部品点数、質量及びコストの増加になってしまう。   However, in the conventional projector-type headlamp 102 shown in FIG. 6, when looking into the back of the lamp through the transparent member 150 from the front of the headlamp, the projector unit 130 disposed on the rear side of the transparent member 150 is located outside the vehicle. Can be visually recognized. Therefore, in order to conceal this, a member (hereinafter referred to as an anti-invisible member) 160 for preventing in-visible is disposed on the vehicle rear side of the transparent member 150. If manufactured separately from the aforementioned lamp components, the number of parts, mass and cost will increase.

本発明は、以上の点に鑑みて創作されたもので、点灯時及び非点灯時の見栄えを従来技術と同等としつつ、部品点数の削減を図ることができる、プロジェクター式ヘッドランプを提供することを目的とする。   The present invention was created in view of the above points, and provides a projector-type headlamp capable of reducing the number of parts while making the appearance at the time of lighting and non-lighting equivalent to the conventional technology. With the goal.

上記目的を達成するため、本発明は、ハウジングとアウターレンズとで画成される灯室内に、バルブを搭載したプロジェクターユニットとバルブから距離を置いてバルブ前方に配置された凸型レンズとを備えたプロジェクター式ヘッドランプであって、凸型レンズの周縁部から傘状に広がった透明樹脂で成る透明部材を有していて、この透明部材がその表面に複数の反射部を有して構成されることを特徴とする。
本発明のプロジェクター式ヘッドランプにおいて、複数の反射部は、透明部材の表面をミラー処理又はハーフミラー処理して成る。また、反射部は、ミラーフィルム或いはハーフミラーフィルムを透明部材の表面及び／又は裏面に貼着して構成されてもよい。
本発明のプロジェクター式ヘッドランプにおいて、透明部材の表面は、車両前側から車両後側へ傾斜面とこの傾斜面の後端から立ち上がった壁面とを繰り返して形成されており、複数の壁面が反射部として構成されている。
本発明のプロジェクター式ヘッドランプにおいて、好ましくは、複数の傾斜面にはシボ加工が施される。 In order to achieve the above object, the present invention includes a projector unit equipped with a bulb and a convex lens placed in front of the bulb at a distance from the bulb in a lamp chamber defined by a housing and an outer lens. The projector-type headlamp has a transparent member made of a transparent resin spreading in an umbrella shape from the peripheral edge of the convex lens, and the transparent member has a plurality of reflecting portions on the surface thereof. It is characterized by that.
In the projector-type headlamp of the present invention, the plurality of reflecting portions are formed by performing mirror processing or half mirror processing on the surface of the transparent member. Moreover, a reflection part may be comprised by sticking a mirror film or a half mirror film on the surface and / or back surface of a transparent member.
In the projector-type headlamp of the present invention, the surface of the transparent member is formed by repeatedly forming an inclined surface and a wall surface rising from the rear end of the inclined surface from the vehicle front side to the vehicle rear side, and the plurality of wall surfaces are reflective portions. It is configured as.
In the projector-type headlamp of the present invention, preferably, the plurality of inclined surfaces are subjected to texture processing.

本発明によれば、点灯時及び非点灯時のヘッドランプの見栄えを従来技術と同等としつつも、透明樹脂でなる透明部材の外表面に、部分蒸着等の鏡面処理とシボの加飾を設定することで灯体内の中見えを防ぐことができる。この場合、従来のヘッドランプで必要としていた中見え防止部材を廃止することができる。   According to the present invention, the appearance of the headlamp at the time of lighting and non-lighting is equivalent to the conventional technology, but the mirror surface treatment such as partial vapor deposition and the embellishment of the texture are set on the outer surface of the transparent member made of transparent resin. By doing so, the inside of the lamp can be prevented. In this case, it is possible to eliminate the anti-seen member required for the conventional headlamp.

以下、図面に基づいて本発明の実施形態を説明する。なお、図中のＦｒは車両前方を、Ｕｐは車両上方を、ＬＨは車両の横幅方向であって左方を示す。
図１は本発明の実施形態に係るプロジェクター式ヘッドランプ（以下、ヘッドランプと呼称する）１の断面図である。図２はヘッドランプ１の一部構成部品の分解斜視図である。
ヘッドランプ１は、ハウジング１０とアウターレンズ２０とで画成される灯室Ｓ内に、バルブ３５を搭載したプロジェクターユニット３０と、バルブ３５から距離を置いてバルブ前方に配置された凸型レンズ４０と、を備えている。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the figure, Fr indicates the front of the vehicle, Up indicates the upper side of the vehicle, and LH indicates the left side in the lateral width direction of the vehicle.
FIG. 1 is a sectional view of a projector-type headlamp (hereinafter referred to as a headlamp) 1 according to an embodiment of the present invention. FIG. 2 is an exploded perspective view of some components of the headlamp 1.
The headlamp 1 includes a projector unit 30 in which a bulb 35 is mounted in a lamp chamber S defined by a housing 10 and an outer lens 20, and a convex lens 40 disposed in front of the bulb at a distance from the bulb 35. And.

ハウジング１０は、図１に示すように、車両前方へ拡開するように広がった椀状のハウジング本体部１１と、このハウジング本体部１１の中心に開けられたサービスホール１１Ａを塞ぐ蓋部１２と、ハウジング本体部１１の下側の開口縁から車両前方へ向けて延出した後底部１３と、この後底部１３の前端から車両前方へ向けて延出した前底部１４と、を備えている。
このように構成されたハウジング１０の縁、具体的にはハウジング本体部１１の上縁及び前底部１４の縁に、アウターレンズ２０のフランジ部が当接するように、ハウジング１０の前側にアウターレンズ２０が配設される。
ハウジング１０及びアウターレンズ２０も樹脂で成るが、アウターレンズ２０は透明樹脂でなる。 As shown in FIG. 1, the housing 10 has a bowl-shaped housing main body 11 that expands to the front of the vehicle, and a lid 12 that closes a service hole 11 </ b> A opened at the center of the housing main body 11. A rear bottom 13 extending toward the front of the vehicle from the lower opening edge of the housing main body 11 and a front bottom 14 extending toward the front of the vehicle from the front end of the rear bottom 13 are provided.
The outer lens 20 is arranged on the front side of the housing 10 such that the flange portion of the outer lens 20 comes into contact with the edge of the housing 10 thus configured, specifically, the upper edge of the housing main body 11 and the edge of the front bottom portion 14. Is disposed.
The housing 10 and the outer lens 20 are also made of resin, but the outer lens 20 is made of transparent resin.

プロジェクターユニット３０は、発光源となるものであり、内部にバルブ３５を着脱可能に搭載したものである。このプロジェクターユニット３０は、図２に示すように、内部にバルブ３５を収容するよう前方に拡開したカップ状の筐体部３１と、この筐体部３１の開口縁から前方に突出した複数のアーム部３２と、これらのアーム部３２の先端部に連結された円環部３３と、から成る。
なお、本実施形態では、バルブ３５としてキセノンヘッドランプを使用しており、ヘッドランプ１がディスチャージヘッドランプ(discharge headlamp)として構成されている。
図示を省略するが、筐体部３１の内部には、バルブ３５からの迷光を前方へ反射するリフレクターが配設されている。
このように構成されるプロジェクターユニット３０は、例えば耐熱性に優れたポリエーテルサルフォン(polyether sulfone:PES)で成る。 The projector unit 30 serves as a light emission source, and has a bulb 35 detachably mounted therein. As shown in FIG. 2, the projector unit 30 includes a cup-shaped casing portion 31 that is widened forward so as to accommodate the bulb 35 therein, and a plurality of protrusions that protrude forward from the opening edge of the casing portion 31. The arm portion 32 includes an annular portion 33 connected to the tip portions of the arm portions 32.
In this embodiment, a xenon headlamp is used as the bulb 35, and the headlamp 1 is configured as a discharge headlamp.
Although not shown, a reflector that reflects stray light from the bulb 35 forward is disposed inside the housing portion 31.
The projector unit 30 configured as described above is made of, for example, polyether sulfone (PES) having excellent heat resistance.

凸型レンズ４０は、バルブ３５からの光を前方へ収束させて照射するものであり、図１に示すように、バルブ側が平坦に形成され、車両前方側へ砲弾状に張り出すように形成されている。この凸型レンズ４０はガラスから成る。
この凸型レンズ４０は、図３に示すように、その周縁を円環部３３の内周面に当接させた状態で、円環部３３と共にレンズホルダー５０によって挟持されて、プロジェクターユニット３０に固定される。 The convex lens 40 irradiates the light from the bulb 35 by converging it forward. As shown in FIG. 1, the convex lens 40 is formed so that the bulb side is flat and is projected in a bullet shape toward the vehicle front side. ing. The convex lens 40 is made of glass.
As shown in FIG. 3, the convex lens 40 is sandwiched by the lens holder 50 together with the annular portion 33 with the periphery thereof being in contact with the inner peripheral surface of the annular portion 33, and is attached to the projector unit 30. Fixed.

このようにして、バルブ３５の前方に配置された凸型レンズ４０に対して、透明部材６０が凸型レンズ４０の周囲に設けられる。この透明部材６０は、その中心領域がレンズ挿入用に開いており、この開口６１（図２）の周囲から傘状に広がった形状を成す。具体的には、透明部材６０は、凸型レンズ４０の周縁部から車両後方へ行くにつれて凸型レンズ４０の中心を貫く仮想水平線Ｌ（図１参照）に対して次第に離れるように傘状に広がるように形成されている。この透明部材６０も、透明樹脂、例えばアクリル樹脂やポリカーボネート樹脂、耐熱性ポリスチレン樹脂などから成形される。
この透明部材６０はプロジェクターユニット３０の円環部３３に係合して、灯室Ｓ内で、凸型レンズ４０の周縁から車両後方側へ向けて傘状に広がるように配設される。具体的には、透明部材６０の開口６１寄りの内周面には爪部６２が設けられており、この爪部６２が係合する孔３３Ａが円環部３３に設けられている。 Thus, the transparent member 60 is provided around the convex lens 40 with respect to the convex lens 40 disposed in front of the bulb 35. The transparent member 60 has a center region that is open for lens insertion, and has a shape that spreads out from the periphery of the opening 61 (FIG. 2) in an umbrella shape. Specifically, the transparent member 60 spreads in an umbrella shape so as to gradually move away from a virtual horizontal line L (see FIG. 1) passing through the center of the convex lens 40 from the peripheral edge of the convex lens 40 toward the rear of the vehicle. It is formed as follows. The transparent member 60 is also formed from a transparent resin such as an acrylic resin, a polycarbonate resin, or a heat resistant polystyrene resin.
The transparent member 60 engages with the annular portion 33 of the projector unit 30 and is disposed in the lamp chamber S so as to spread in an umbrella shape from the periphery of the convex lens 40 toward the vehicle rear side. Specifically, a claw portion 62 is provided on the inner peripheral surface near the opening 61 of the transparent member 60, and a hole 33 </ b> A with which the claw portion 62 engages is provided in the annular portion 33.

さらに、本実施形態の透明部材６０は、外側表面にミラー処理が施された複数の反射部を有する。
ここで、図４は透明部材６０の外側表面の部分、具体的には図１の破線の円で囲んだ領域部分の拡大斜視図であり、この図に示すように、透明部材６０の外表面は、車両前側から車両後側へ行くにつれて傾斜面６０Ａとこの傾斜面６０Ａの後端から立ち上がった壁面６０Ｂとを繰り返して形成されており、これらの複数の壁面６０Ｂ、図２中の斜線領域にミラー処理が施されている。例えば、壁面６０Ｂには、アルミニウム蒸着処理が施されている。このように、壁面６０Ｂに入射した光をアルミニウムで完全に反射させる代わりに、壁面６０Ｂにハーフミラー処理を施してもよい。このようなミラー処理が施される壁面６０Ｂは、車両前方側と対向するように面が広がっている。
さらに、本実施形態の透明部材６０では、複数の傾斜面６０Ａにシボ加工を施して、透明部材６０の奧側への光の採光を確保しつつライト外部から透明部材６０の奧側が直接視認されることを防止している。シボ加工の模様としては、皮革模様に限らず、木目、岩目、砂目、幾何学模様などであってもよい。
なお、透明部材６０の内側は、湾曲面として構成されている。 Furthermore, the transparent member 60 of the present embodiment has a plurality of reflecting portions that are mirrored on the outer surface.
4 is an enlarged perspective view of a portion of the outer surface of the transparent member 60, specifically, a region portion surrounded by a broken-line circle in FIG. 1, and as shown in FIG. Is formed by repeatedly forming an inclined surface 60A and a wall surface 60B rising from the rear end of the inclined surface 60A from the front side of the vehicle to the rear side of the vehicle. Mirror processing is applied. For example, the wall surface 60B is subjected to aluminum vapor deposition. Thus, instead of completely reflecting the light incident on the wall surface 60B with aluminum, the wall surface 60B may be subjected to a half mirror process. The wall surface 60B on which such mirror processing is performed has a wide surface so as to face the front side of the vehicle.
Furthermore, in the transparent member 60 of the present embodiment, the plurality of inclined surfaces 60 </ b> A are subjected to a graining process, and the heel side of the transparent member 60 is directly visually recognized from the outside of the light while ensuring the lighting of light toward the heel side of the transparent member 60. Is prevented. The texture pattern is not limited to a leather pattern, and may be a wood grain, rock grain, sand grain, geometric pattern, or the like.
The inner side of the transparent member 60 is configured as a curved surface.

本実施形態に係るヘッドランプは、さらに、透明部材６０とアウターレンズ上側のフランジ部との隙間を埋めるように、灯室Ｓ内に第１エクステンション７１を設け、さらに、透明部材６０の下縁とアウターレンズ下側のフランジ部との隙間を埋めるように第２エクステンション７２及び第３エクステンション７３を設けている。これらの第１〜３のエクステンションは、所謂メインライトと所謂サブライトの両方をつなぎ包む部材である。   The headlamp according to the present embodiment further includes a first extension 71 in the lamp chamber S so as to fill a gap between the transparent member 60 and the upper flange portion of the outer lens. A second extension 72 and a third extension 73 are provided so as to fill a gap with the flange portion on the lower side of the outer lens. These first to third extensions are members that connect and wrap both the so-called main light and the so-called sub light.

このように構成されたヘッドランプ１によれば、日中には透明部材６０、具体的には複数の傾斜面６０Ａを介して凸型レンズ４０の奥部、即ちバルブ周辺領域が光に照らされるため、灯体内を明るくすることができる。
夜間では、バルブ３５からの光が凸型レンズ４０を介して車両前方を照らし、さらに、透明部材６０の傾斜面６０Ａからもバルブ３５からの光を外側に照射させるため、ヘッドランプ１を正面から見た場合、凸型レンズ４０の周りにリング状に発光する領域を形成することができる。 According to the headlamp 1 configured in this way, during the day, the back of the convex lens 40, that is, the bulb peripheral region is illuminated with light through the transparent member 60, specifically, the plurality of inclined surfaces 60A. Therefore, the lamp body can be brightened.
At night, the light from the bulb 35 illuminates the front of the vehicle through the convex lens 40, and further, the light from the bulb 35 is also emitted to the outside from the inclined surface 60A of the transparent member 60. When viewed, a region that emits light in a ring shape can be formed around the convex lens 40.

また、ヘッドランプ１の正面から透明部材６０を介してランプの奥側を覗いた場合、透明部材６０の壁面６０Ｂにミラー処理が施されていると共に傾斜面６０Ａにはシボ加工が施されていて、壁面６０Ｂに入射した光が車両前方側へ反射されるので、ヘッドランプ１の正面からランプ奧側を直接視認することが規制されている。   Further, when the back side of the lamp is viewed from the front of the headlamp 1 through the transparent member 60, the wall surface 60B of the transparent member 60 is subjected to mirror processing and the inclined surface 60A is subjected to embossing. Since the light incident on the wall surface 60B is reflected to the front side of the vehicle, direct viewing of the lamp lamp side from the front of the headlamp 1 is restricted.

このように、本発明の実施形態に係るヘッドランプ１によれば、点灯時及び非点灯時のヘッドランプ１の見栄えを従来技術と同等としつつも、透明樹脂でなる透明部材６０の外表面に、部分蒸着とシボの加飾を設定することで灯体内の中見えを防ぐことができる。この場合、従来のヘッドランプで必要としていた中見え防止部材を廃止することができる。   As described above, according to the headlamp 1 according to the embodiment of the present invention, the appearance of the headlamp 1 at the time of lighting and at the time of non-lighting is equivalent to that of the conventional technology, but on the outer surface of the transparent member 60 made of a transparent resin. By setting partial vapor deposition and grain decoration, the inside of the lamp can be prevented from being seen. In this case, it is possible to eliminate the anti-seen member required for the conventional headlamp.

以上詳述したが、本発明はその趣旨を逸脱しない範囲において様々な形態で実施をすることができる。
上記説明では、透明部材の外側表面にミラー処理とシボ加工処理とを施した構成を示したが、本発明における透明部材はシボ加工を省略して構成されてもよい。
上記説明におけるミラー処理及びハーフミラー処理は、透明部材の表面にアルミニウム等を蒸着する処理に限らず、ミラーフィルム又はハーフミラーフィルムを透明部材の外側表面に被着させる構成を含む。
透明部材の外側表面に施したミラー処理とシボ加工処理とは透明部材の内側表面に施しても良い。この場合、透明部材の外側表面は湾曲面として構成され、内側表面は傾斜面と壁面とが車両前側から後側にかけて繰り返して形成される。
本発明におけるヘッドランプ、即ちプロジェクター式ヘッドランプは、白熱電球タイプにも適用できることは勿論である。 Although detailed above, the present invention can be implemented in various forms without departing from the spirit of the present invention.
In the above description, the configuration in which the outer surface of the transparent member is subjected to the mirror processing and the texture processing is shown, but the transparent member in the present invention may be configured by omitting the texture processing.
The mirror process and the half mirror process in the above description are not limited to the process of depositing aluminum or the like on the surface of the transparent member, but include a configuration in which a mirror film or a half mirror film is deposited on the outer surface of the transparent member.
The mirror treatment and the texture treatment applied to the outer surface of the transparent member may be performed on the inner surface of the transparent member.
