＜実施の形態２＞
次に、本発明の実施の形態２を図４〜図６に基づいて説明する。 <Embodiment 2>
Next, a second embodiment of the present invention will be described with reference to FIGS.

図４は本発明の実施の形態２に係る灯具の側断面図、図５は図４のＣ部拡大詳細図、図６は同灯具のハウジングを開いた状態を示す斜視図である。   4 is a side sectional view of a lamp according to Embodiment 2 of the present invention, FIG. 5 is an enlarged detail view of a portion C in FIG. 4, and FIG. 6 is a perspective view showing a state in which the housing of the lamp is opened.

本実施の形態に係る灯具２１は、車両のバンパ３０の内側に直接取り付けられるものであって、図４に示すようにハウジング２２の外部に導光体２３を取り付けて構成されている。ここで、ハウジング２２は、図６に示すように、矩形ボックス状の上蓋２２Ａと下蓋２２Ｂをヒンジ２２ａによって連結して構成されており、ヒンジ２２ａを中心として上蓋２２Ａを回転させてこれを下蓋２２Ｂに被せることによって図１に示すように内部が密閉されたハウジング２２が形成される。尚、上蓋２２Ａと下蓋２２Ｂとの合わせ部はシール部材２４によって気密にシールされている。   The lamp 21 according to the present embodiment is directly attached to the inside of the bumper 30 of the vehicle, and is configured by attaching a light guide 23 to the outside of the housing 22 as shown in FIG. Here, as shown in FIG. 6, the housing 22 is configured by connecting a rectangular box-shaped upper lid 22A and lower lid 22B by a hinge 22a, and rotating the upper lid 22A around the hinge 22a to lower it. By covering the lid 22B, a housing 22 whose inside is sealed is formed as shown in FIG. Note that the joining portion of the upper lid 22A and the lower lid 22B is hermetically sealed by a seal member 24.

そして、ハウジング２２内の密閉空間内には光源であるＬＥＤ２５が収容されている。即ち、ＬＥＤ２５はＬＥＤ基板２６の中央に実装されており、ＬＥＤ基板２６は、ハウジング２２の下蓋２２Ｂの内底面に複数のネジ２７によって取り付けられている。   An LED 25 that is a light source is housed in a sealed space in the housing 22. That is, the LED 25 is mounted in the center of the LED substrate 26, and the LED substrate 26 is attached to the inner bottom surface of the lower lid 22 </ b> B of the housing 22 with a plurality of screws 27.

又、ハウジング２２の上蓋２２ＡのＬＥＤ２５に対向する部位には円形の開口部２２ｂが形成されており、上蓋２２Ａの上面の開口２２ｂが形成された周囲には円筒状の嵌合ボス２２ｃが立設されている。ここで、嵌合ボス２２ｃの内周面は図５に示すように上方に向かって開くテーパ面として形成されている。   In addition, a circular opening 22b is formed in a portion of the upper cover 22A of the housing 22 facing the LED 25, and a cylindrical fitting boss 22c is erected around the opening 22b on the upper surface of the upper cover 22A. Has been. Here, the inner peripheral surface of the fitting boss 22c is formed as a tapered surface that opens upward as shown in FIG.

他方、ハウジング２２の下蓋２２Ｂには垂直下方に延びる取付ブラケット２２Ｃが一体に形成されており、この取付ブラケット２２Ｃには円孔２２ｄが形成されている。   On the other hand, a mounting bracket 22C extending vertically downward is integrally formed on the lower cover 22B of the housing 22, and a circular hole 22d is formed in the mounting bracket 22C.

而して、図４に示すように、ハウジング２２の上蓋２２Ａの上面に形成された嵌合ボス２２ｃには導光体２３が取り付けられている。即ち、導光体２３の下面には下方に向かって縮径するテーパ嵌合部２３ａが一体に形成されており、このテーパ嵌合部２３ａをハウジング２２の上蓋２２Ａに形成された嵌合ボス２２ｃの内周のテーパ面に嵌め込み、導光体２３がハウジング２２の上蓋２２Ａに取り付けられる。尚、この場合、導光体２３のテーパ嵌合部２３ａとハウジング２２の上蓋２２Ａの開口部２２ｂの周縁との間にはシール部材２８が介装されており、導光体２３のテーパ嵌合部２３ａと上蓋２２Ａの嵌合ボス２２ｃの間には０．０５ｍｍ程度の隙間δが形成されて位置決めされる。   Thus, as shown in FIG. 4, a light guide 23 is attached to the fitting boss 22 c formed on the upper surface of the upper cover 22 </ b> A of the housing 22. That is, a taper fitting portion 23a that is reduced in diameter downward is integrally formed on the lower surface of the light guide 23, and the taper fitting portion 23a is formed as a fitting boss 22c formed on the upper lid 22A of the housing 22. The light guide 23 is attached to the upper lid 22 </ b> A of the housing 22. In this case, a seal member 28 is interposed between the tapered fitting portion 23a of the light guide 23 and the peripheral edge of the opening 22b of the upper cover 22A of the housing 22, and the tapered fitting of the light guide 23 is performed. A gap δ of about 0.05 mm is formed and positioned between the portion 23a and the fitting boss 22c of the upper lid 22A.

そして、ハウジング２２の上蓋２２Ａに導光体２３が取り付けられた灯具２１は、図１に示すように、ハウジング２２の下蓋２２Ａに形成された取付ブラケット２２Ｃを車両のバンパ３０の裏側に突設されたステー３１に当て、該取付ブラケット２２Ｃに形成された円孔２２ｄに挿通するネジ２９をステー３１にねじ込むことによってバンパ３０の裏側に直接取り付けられる。このとき、灯具２１の導光体２３の先端部はバンパ３０に形成された開口部３０ａから外部に露出している。   The lamp 21 having the light guide 23 attached to the upper lid 22A of the housing 22 is provided with a mounting bracket 22C formed on the lower lid 22A of the housing 22 on the back side of the bumper 30 of the vehicle, as shown in FIG. The screws 29 are directly attached to the back side of the bumper 30 by being screwed into the stays 31 with the screws 29 inserted into the circular holes 22d formed in the mounting brackets 22C. At this time, the tip of the light guide 23 of the lamp 21 is exposed to the outside from the opening 30 a formed in the bumper 30.

以上のように構成された灯具２１において、光源であるＬＥＤ２５に不図示の電源（バッテリ）から電流が供給されると、該ＬＥＤ２５が起動されて発光し、その光は導光体２３の入射面２３ｂから入射する。そして、導光体２３に入射した光は、該導光体２３内を全反射しながら車両前方（図４の左方）へと進行し、そのバンパ３０の開口部３０ａから露出する前端の出射面２３ｃから車両前方に向かって出射する。   In the lamp 21 configured as described above, when an electric current (battery) (not shown) is supplied to the LED 25 that is a light source, the LED 25 is activated to emit light, and the light is incident on the light guide 23. It enters from 23b. The light incident on the light guide 23 travels forward of the vehicle (leftward in FIG. 4) while being totally reflected in the light guide 23, and is emitted from the front end exposed from the opening 30a of the bumper 30. The light exits from the surface 23c toward the front of the vehicle.

而して、本実施の形態に係る灯具２１においても、光源であるＬＥＤ２５を収容するハウジング２２の外部に導光体２３を配置したため、灯具２１全体の高さを低く抑えて該灯具２１の薄型化を図ることができるとともに、灯具２１の配置スペースを小さく抑えて省スペース化を図ることができる。   Thus, also in the lamp 21 according to the present embodiment, since the light guide 23 is disposed outside the housing 22 that houses the LED 25 that is a light source, the overall height of the lamp 21 is kept low, and the lamp 21 is thin. In addition, the space for the lamp 21 can be reduced and the space can be saved.

尚、本実施の形態では、導光体２３をハウジング２２の上蓋２２Ａに取り付けたが、ハウジング２２の下蓋２２Ｂに導光体２３を取り付け、ＬＥＤ２５を実装したＬＥＤ基板２６をハウジング２２内の上蓋２２Ａの天井面にＬＥＤ２５の光出射方向が下向きになるよう取り付ける構成を採用しても良い。又、以上は本発明をヘッドランプに対して適用した形態について説明したが、本発明は他の任意のランプに対しても同様に適用可能であることは勿論である。   In this embodiment, the light guide 23 is attached to the upper cover 22A of the housing 22. However, the light guide 23 is attached to the lower cover 22B of the housing 22 and the LED board 26 on which the LED 25 is mounted is attached to the upper cover in the housing 22. You may employ | adopt the structure attached so that the light emission direction of LED25 may become downward on the ceiling surface of 22A. In the above, the embodiment in which the present invention is applied to a headlamp has been described. However, the present invention is naturally applicable to other arbitrary lamps as well.
