Yes.

そして、図６に示すように、複数個、この例では、６個の前記車両用灯具１は、アウターレンズもしくはアウターカバー（図示せず）とランプハウジング１８とに区画された灯室（図示せず）内に配置され、かつ、前記ランプハウジング１８にホルダ１９などを介して取り付けられている。前記６個の車両用灯具１は、車両（図示せず）に、前記第１反射面２の光軸Ｚ−Ｚを車両の進行軸Ｈ−Ｈとほぼ平行になるように、搭載される。   As shown in FIG. 6, a plurality of, in this example, six vehicle lamps 1, are lamp chambers (not shown) partitioned into an outer lens or outer cover (not shown) and a lamp housing 18. And is attached to the lamp housing 18 via a holder 19 or the like. The six vehicular lamps 1 are mounted on a vehicle (not shown) so that the optical axis ZZ of the first reflecting surface 2 is substantially parallel to the traveling axis HH of the vehicle.

以下、この実施例における車両用灯具１の作用について説明する。まず、６個の車両用灯具１のＬＥＤ６の発光部１５を点灯発光させる。すると、ＬＥＤ６の発光部１５から放射された光（図１および図２中の実線矢印および破線矢印にて示す）の大部分は、第１反射面２で反射され、残りの部分は、第２開口部１２を経て主に第３反射面１６に直接入射する。第１反射面２で反射された反射光は、第２開口部１２を経て第１反射面２の第２焦点Ｆ２に進む。この第２焦点Ｆ２において、反射光の一部は、シェード４によりカットオフされ、残りの反射光は、主に第２反射３に入射する。   Hereinafter, the operation of the vehicular lamp 1 in this embodiment will be described. First, the light emitting portions 15 of the LEDs 6 of the six vehicular lamps 1 are turned on. Then, most of the light radiated from the light emitting portion 15 of the LED 6 (shown by solid line arrows and broken line arrows in FIGS. 1 and 2) is reflected by the first reflecting surface 2, and the remaining part is second. The light directly enters the third reflecting surface 16 mainly through the opening 12. The reflected light reflected by the first reflecting surface 2 proceeds to the second focal point F2 of the first reflecting surface 2 through the second opening 12. At the second focal point F <b> 2, part of the reflected light is cut off by the shade 4, and the remaining reflected light is mainly incident on the second reflection 3.

第２反射面３に入射した光は、この第２反射面３で反射される。この第２反射面３で反射された反射光Ｌ１は、図１に示すように、水平軸Ｈ−Ｈに対して若干下側に向けて照射される。この結果、図４に示すように、シェード４のエッジ部１３によりカットラインＣＬが上縁に形成された所定の配光パターン、この例では、すれ違い用の配光パターンＬＰは、路面などを照明する。   The light incident on the second reflecting surface 3 is reflected by the second reflecting surface 3. As shown in FIG. 1, the reflected light L1 reflected by the second reflecting surface 3 is irradiated slightly downward with respect to the horizontal axis H-H. As a result, as shown in FIG. 4, the predetermined light distribution pattern in which the cut line CL is formed on the upper edge by the edge portion 13 of the shade 4, in this example, the light distribution pattern LP for passing illuminates the road surface and the like. To do.

一方、第３反射面１６に入射した光は、この第３反射面１６で反射される。この第３反射面１６で反射された反射光Ｌ２は、図１に示すように、水平軸Ｈ−Ｈに対してやや上側に向けて照射される。この結果、図４に示すように、所定の配光パターン、この例では、オーバーヘッドサイン用の配光パターンＯＰは、すれ違い用の配光パターンＬＰの上方のオーバーヘッドサインなどを照明する。   On the other hand, the light incident on the third reflecting surface 16 is reflected by the third reflecting surface 16. As shown in FIG. 1, the reflected light L <b> 2 reflected by the third reflecting surface 16 is irradiated toward the horizontal axis HH slightly upward. As a result, as shown in FIG. 4, the predetermined light distribution pattern, in this example, the overhead sign light distribution pattern OP illuminates an overhead sign or the like above the passing light distribution pattern LP.

ここで、６個の車両用灯具１のうち、任意の個数の車両用灯具１の第２反射面３を拡散タイプの反射面としてその車両用灯具１をすれ違い用の配光パターンＬＰ形成用とし、残りの車両用灯具１の第２反射面３を集光タイプの反射面としてその車両用灯具１をホットゾーンＨＺ形成用とする。すると、図４に示すように、すれ違い用の配光パターンＬＰと、そのほぼ中央部（左側Ｌ８°から右側Ｒ８°までの範囲）に位置するホットゾーンＨＺとが得られる。   Here, of the six vehicular lamps 1, the second reflecting surface 3 of an arbitrary number of vehicular lamps 1 is used as a diffusion type reflecting surface, and the vehicular lamp 1 is used to form a light distribution pattern LP for passing. The second reflecting surface 3 of the remaining vehicular lamp 1 is used as a condensing type reflecting surface, and the vehicular lamp 1 is used for forming a hot zone HZ. Then, as shown in FIG. 4, a light distribution pattern LP for passing and a hot zone HZ located in a substantially central portion (range from the left side L8 ° to the right side R8 °) are obtained.

以下、この実施例における車両用灯具の効果について説明する。この実施例における車両用灯具１は、図１および図４に示すように、第２反射面３で反射された反射光Ｌ１がすれ違い用の配光パターンＬＰで路面などを照明し、また、第３反射面１６で反射された反射光Ｌ２がオーバーヘッドサイン用の配光パターンＯＰで路面の上のオーバーヘッドサインなどを照明することができる。このように、この実施例における車両用灯具１は、オーバーヘッドサインを照明するのに適している。   Hereinafter, effects of the vehicular lamp in this embodiment will be described. As shown in FIGS. 1 and 4, the vehicular lamp 1 in this embodiment illuminates the road surface with a light distribution pattern LP for passing the reflected light L1 reflected by the second reflecting surface 3, The reflected light L2 reflected by the three reflecting surfaces 16 can illuminate an overhead sign or the like on the road surface with the light distribution pattern OP for overhead signs. Thus, the vehicular lamp 1 in this embodiment is suitable for illuminating an overhead sign.

しかも、この実施例における車両用灯具１は、第２反射面２に第３反射面１６を設けるだけであるから、その他の部品、たとえば、第１反射面２、シェード４、ＬＥＤ６の配置を変える必要がない。このために、この実施例における車両用灯具１は、簡単なマイナーチェンジにより提供することができ、製造コストのアップを抑制することができる。   In addition, since the vehicular lamp 1 in this embodiment is merely provided with the third reflecting surface 16 on the second reflecting surface 2, the arrangement of other components such as the first reflecting surface 2, the shade 4, and the LED 6 is changed. There is no need. For this reason, the vehicular lamp 1 in this embodiment can be provided by a simple minor change, and an increase in manufacturing cost can be suppressed.

特に、この実施例における車両用灯具１は、図１に示すように、第１反射面２の光軸Ｚ−Ｚがほぼ水平な第２反射面３の光軸Ｚ１−Ｚ１に対して斜めに傾斜している。この結果、この実施例における車両用灯具１は、各構成部品（第１反射面２、第２反射面３、第３反射面１６、ＬＥＤ６など）が斜めに傾斜する第１反射面２の光軸Ｚ−Ｚと第２反射面３の光軸Ｚ１−Ｚ１に対してレイアウトされるので、斜めに傾斜する第１反射面２の光軸Ｚ−Ｚと第２反射面３の光軸Ｚ１−Ｚ１との傾斜の度合いを調整することにより、各構成部品のレイアウト設計の自由度が増して大きくなる。   In particular, as shown in FIG. 1, the vehicular lamp 1 in this embodiment is inclined with respect to the optical axis Z1-Z1 of the second reflecting surface 3 in which the optical axis ZZ of the first reflecting surface 2 is substantially horizontal. Inclined. As a result, the vehicular lamp 1 according to this embodiment is configured such that each component (the first reflecting surface 2, the second reflecting surface 3, the third reflecting surface 16, the LED 6 and the like) is light on the first reflecting surface 2 in which the components are inclined obliquely. Since it is laid out with respect to the axis ZZ and the optical axis Z1-Z1 of the second reflecting surface 3, the optical axis ZZ of the first reflecting surface 2 and the optical axis Z1- By adjusting the degree of inclination with respect to Z1, the degree of freedom in layout design of each component increases and increases.

ここで、第二反射面（４）の光軸（Ｙ）が照射方向（Ｘ１）に対して直交する前記の特許文献１の車両用灯具（１０）では、収納スペースが照射方向（Ｘ１）に対して直交する方向に大きくなり、また、反射面の光軸と光照射方向とが一致する車両用灯具では、収納スペースが光照射方向に大きくなる。これに対して、この実施例における車両用灯具１は、第１反射面２の光軸Ｚ−Ｚと第２反射面３の光軸Ｚ１−Ｚ１、すなわち、光照射方向とが斜めであるから、車両用灯具１の収納スペースが光照射方向に対して直交する方向、または、光照射方向に大きくならず、ほどほどの収納スペース内で収納されるので、収納スペース面でも優れている。   Here, in the vehicle lamp (10) of Patent Document 1 in which the optical axis (Y) of the second reflecting surface (4) is orthogonal to the irradiation direction (X1), the storage space is in the irradiation direction (X1). In the vehicular lamp in which the optical axis of the reflecting surface coincides with the light irradiation direction, the storage space increases in the light irradiation direction. On the other hand, in the vehicle lamp 1 in this embodiment, the optical axis ZZ of the first reflecting surface 2 and the optical axis Z1-Z1 of the second reflecting surface 3, that is, the light irradiation direction are oblique. The storage space of the vehicular lamp 1 does not increase in the direction perpendicular to the light irradiation direction or in the light irradiation direction, and is stored in a moderate storage space.

しかも、この実施例における車両用灯具１は、同じく、図１に示すように、第１反射面２が第２反射面３および第３反射面１６に対して前側でかつ斜め下側に位置しており、この第１反射面２およびＬＥＤ６側と第２反射面３および第３反射面１６側との間に第２開口部１２を設けたものである。このために、この実施例における車両用灯具１は、ＬＥＤ６の発熱を熱対流で、すなわち、下側の第１開口部１１から上側の第２開口部１２に流れる熱対流で、ＬＥＤ６より上方に位置する第２開口部１２から外部に効率良く放出することができ、ＬＥＤ６の放熱効果に優れている。   Moreover, in the vehicle lamp 1 in this embodiment, as shown in FIG. 1, the first reflecting surface 2 is located on the front side and obliquely below the second reflecting surface 3 and the third reflecting surface 16. The second opening 12 is provided between the first reflecting surface 2 and the LED 6 side and the second reflecting surface 3 and the third reflecting surface 16 side. For this reason, the vehicular lamp 1 in this embodiment has the heat generated by the LED 6 by heat convection, that is, by heat convection flowing from the lower first opening 11 to the upper second opening 12 and above the LED 6. It can discharge | emit efficiently from the 2nd opening part 12 located outside, and is excellent in the heat dissipation effect of LED6.

また、この実施例における車両用灯具１は、図１に示すように、ＬＥＤ６の０°の軸Ｚ０−Ｚ０が第１反射面２の光軸Ｚ−Ｚに対して、第１反射面２の光反射方向と逆側（すなわち、第１反射面２の光軸Ｚ−Ｚと垂直な軸ＺＶ−ＺＶに対して下側）に傾斜している。このために、この実施例における車両用灯具１は、ＬＥＤ６の０°の軸Ｚ０−Ｚ０が第１反射面２の光軸Ｚ−Ｚと垂直な軸ＺＶ−ＺＶと合致させた場合のものと比較して、ＬＥＤ６からの直射光であって、第２開口部１２を通って第３反射面１６に入射する光の量を少なくすることができ、その分、ＬＥＤ６から第１反射面２に入射する光の量を増すことができる。この結果、この実施例における車両用灯具１は、ＬＥＤ６からの光を有効利用することができ、路面を明るく照明することができる。なお、第３反射面１６に入射するＬＥＤ６からの直射光の量が少なくなったとしても、この第３反射面１６からの反射光Ｌ３は、オーバーヘッドサイン用の配光パターンＯＰでオーバーヘッドサインを照明するものであるから、オーバーヘッドサインの照明に何ら支障をきたすことがなく、かつ、対向車や先行車などにグレアを与えるようなことがない。   In addition, as shown in FIG. 1, the vehicular lamp 1 in this embodiment is configured such that the 0 ° axis Z0-Z0 of the LED 6 is relative to the optical axis ZZ of the first reflecting surface 2. It is inclined to the opposite side to the light reflection direction (that is, the lower side with respect to the axis ZV-ZV perpendicular to the optical axis ZZ of the first reflecting surface 2). For this reason, the vehicular lamp 1 in this embodiment is obtained when the 0 ° axis Z0-Z0 of the LED 6 is aligned with the axis ZV-ZV perpendicular to the optical axis ZZ of the first reflecting surface 2. In comparison, the amount of light that is direct light from the LED 6 and incident on the third reflecting surface 16 through the second opening 12 can be reduced, and the amount from the LED 6 to the first reflecting surface 2 can be reduced accordingly. The amount of incident light can be increased. As a result, the vehicular lamp 1 in this embodiment can effectively use the light from the LED 6 and can illuminate the road surface brightly. Even if the amount of direct light from the LED 6 incident on the third reflecting surface 16 decreases, the reflected light L3 from the third reflecting surface 16 illuminates the overhead sign with the light distribution pattern OP for overhead sign. Therefore, the overhead sign lighting is not hindered, and glare is not given to oncoming vehicles and preceding vehicles.

さらに、この実施例における車両用灯具１は、第１反射面２の第２焦点Ｆ２近傍に第１反射面２からの反射光の一部をカットオフして残りの反射光で、図４に示すような上縁にカットラインＣＬが形成されているすれ違い用の配光パターンＬＰを形成するシェード４が設けられている。このために、この実施例における車両用灯具１は、上縁にカットラインＣＬが形成されているすれ違い用の配光パターンＬＰが得られるので、路面を照明する車両用灯具、たとえば、前照灯に適している。   Further, the vehicular lamp 1 in this embodiment cuts off part of the reflected light from the first reflecting surface 2 near the second focal point F2 of the first reflecting surface 2 and uses the remaining reflected light as shown in FIG. A shade 4 for forming a light distribution pattern LP for passing, in which a cut line CL is formed at the upper edge as shown, is provided. For this reason, the vehicular lamp 1 in this embodiment can obtain a passing light distribution pattern LP having a cut line CL formed at the upper edge, so that a vehicular lamp that illuminates the road surface, for example, a headlamp Suitable for

なお、この実施例における車両用灯具１においては、ＬＥＤ６の０°の軸Ｚ０−Ｚ０が第１反射面２の光軸Ｚ−Ｚに対して第１反射面２の光反射方向と逆側に傾斜しているものである。ところが、この発明においては、ＬＥＤ６の０°の軸Ｚ０−Ｚ０が第１反射面２の光軸Ｚ−Ｚと垂直な軸ＺＶ−ＺＶと合致させたものであっても良い。   In the vehicular lamp 1 in this embodiment, the 0 ° axis Z0-Z0 of the LED 6 is opposite to the light reflection direction of the first reflection surface 2 with respect to the optical axis ZZ of the first reflection surface 2. It is inclined. However, in the present invention, the 0 ° axis Z0-Z0 of the LED 6 may coincide with the axis ZV-ZV perpendicular to the optical axis ZZ of the first reflecting surface 2.

また、この実施例における車両用灯具１においては、第１反射面２の第２焦点Ｆ２近傍に第１反射面２からの反射光の一部をカットオフして残りの反射光ですれ違い用の配光パターンＬＰを形成するシェード４が設けられているものである。ところが、この発明においては、シェード４を設けずに、上縁にカットラインがない所定の配光パターンが得られるものであっても良い。   Further, in the vehicle lamp 1 in this embodiment, a part of the reflected light from the first reflecting surface 2 is cut off in the vicinity of the second focal point F2 of the first reflecting surface 2, and the remaining reflected light is used for passing. A shade 4 for forming the light distribution pattern LP is provided. However, in the present invention, a predetermined light distribution pattern having no cut line at the upper edge may be obtained without providing the shade 4.

さらに、この実施例における車両用灯具１においては、第２反射面３からの反射光Ｌ１によるすれ違い用の配光パターンＬＰと、第３反射面１６からの反射光Ｌ２によるオーバーヘッドサイン用の配光パターンＯＰとが得られ、すれ違い用ランプとオーバーヘッドサイン用ランプとを兼用することができるものである。ところが、この発明においては、第３反射面１６の面積を第２反射面３の面積よりも広くして、第３反射面１６からの反射光Ｌ２によるオーバーヘッドサイン用の配光パターンＯＰの光量を第２反射面３からの反射光Ｌ１による路面用の配光パターンの光量よりも多くすることができるので、車両用灯具１をオーバーヘッドサイン照明用の専用ランプとすることができる。この場合、第２反射面３からの反射光Ｌ１による路面用の配光パターンは、他のランプから照射される配光パターンの補助として使用される。   Furthermore, in the vehicular lamp 1 in this embodiment, the light distribution pattern LP for passing by the reflected light L1 from the second reflecting surface 3 and the light distribution for overhead sign by the reflected light L2 from the third reflecting surface 16 are used. A pattern OP is obtained, and the passing lamp and the overhead sign lamp can be used together. However, in the present invention, the area of the third reflecting surface 16 is made larger than the area of the second reflecting surface 3, and the amount of light of the overhead sign light distribution pattern OP by the reflected light L2 from the third reflecting surface 16 is set. Since the amount of light of the light distribution pattern for the road surface by the reflected light L1 from the second reflecting surface 3 can be increased, the vehicular lamp 1 can be a dedicated lamp for overhead sign illumination. In this case, the light distribution pattern for the road surface by the reflected light L1 from the second reflecting surface 3 is used as an auxiliary to the light distribution pattern irradiated from another lamp.
