Light up slightly.

以上の（ａ），（ｂ）に示したように、ロービーム用ランプ９１の光源を、前方を直接照らす第１ＬＥＤ群１３１と、アッパーリフレクタ９５で反射させて前方を照らす第２ＬＥＤ群１３２とで構成したことで、明るい照明装置を得ることができる。   As shown in (a) and (b) above, the light source of the low beam lamp 91 is composed of the first LED group 131 that directly illuminates the front, and the second LED group 132 that illuminates the front by being reflected by the upper reflector 95. As a result, a bright illumination device can be obtained.

図６（ａ），（ｂ）は本発明に係るヘッドランプの作用を示す第２作用図である。

以上の図５（ｂ）及び図６（ｂ）で示したように、ロービーム用ランプ９１及びハイビーム用ランプ９２の一方を点灯したときに、ロービーム用ランプ９１及びハイビーム用ランプ９２の他方を発光させることができるため、常にヘッドランプ４７の全体を発光させることができ、遠くからのヘッドランプ４７の視認性を向上させることができる。   As shown in FIGS. 5B and 6B, when one of the low beam lamp 91 and the high beam lamp 92 is turned on, the other of the low beam lamp 91 and the high beam lamp 92 is caused to emit light. Therefore, the entire headlamp 47 can always emit light, and the visibility of the headlamp 47 from a distance can be improved.

以上の図４で示したように、本発明は第１に、前方に向いた第１の光源としての第１ＬＥＤ群１３１と、この第１ＬＥＤ群１３１よりも後方に位置するとともに前方を向いたアッパーリフレクタ９５とを備えた照明装置としてのヘッドランプ４７において、第１ＬＥＤ群１３１の後方にアッパーリフレクタ９５に向けて光を照射する第２の光源としての第２ＬＥＤ群１３２を設けたことを特徴とする。   As shown in FIG. 4, the present invention firstly includes a first LED group 131 as a first light source facing forward, and an upper positioned forward and forward of the first LED group 131.

これにより、第１ＬＥＤ群１３１からの直接光と、アッパーリフレクタによる第２ＬＥＤ群１３２の反射光とによって前方を明るく照らすことができ、明るいヘッドランプ４７を得ることができる。   Thereby, the front can be brightly illuminated by the direct light from the first LED group 131 and the reflected light of the second LED group 132 by the upper reflector, and the bright headlamp 47 can be obtained.

本発明は第２に、図３及び図４に示したように、第２ＬＥＤ群１３２を、第１ＬＥＤ群１３１と正面から見て重なり合う位置に配置したことを特徴とする。
これにより、ヘッドランプ４７、詳しくは、光源部１２５の上下及び左右の寸法を小さくすることができ、ヘッドランプ４７の小型化、コンパクト化を図ることができる。また、光源部１２５が小さくなるため、アッパーリフレクタ９５の反射面積を大きくすることができる。 Secondly, the present invention is characterized in that, as shown in FIGS. 3 and 4, the second LED group 132 is arranged at a position overlapping the first LED group 131 when viewed from the front.
Thereby, the vertical and horizontal dimensions of the headlamp 47, specifically the light source unit 125, can be reduced, and the headlamp 47 can be reduced in size and size. Moreover, since the light source part 125 becomes small, the reflective area of the upper reflector 95 can be enlarged.

本発明は第３に、図４に示したように、第２ＬＥＤ群１３２を構成するＬＥＤ単体１３１の軸線１３１ａをアッパーリフレクタ９５に向けて配置したことを特徴とする。

本発明は第４に、第１ＬＥＤ群１３１及び第２ＬＥＤ群１３２を、ＬＥＤ、即ちＬＥＤ単体１３１で構成したことを特徴とする。
これにより、消費電力を抑えながら所定の明るさを確保することができ、バッテリの容量を小さくすることができる。 Fourthly, the present invention is characterized in that the first LED group 131 and the second LED group 132 are constituted by LEDs, that is, the LED unit 131.
Thereby, predetermined brightness can be ensured while suppressing power consumption, and the capacity of the battery can be reduced.

本発明は第５に、第１ＬＥＤ群１３１の前方に光を拡散する球体レンズ１２９を配置したことを特徴とする。
第１ＬＥＤ群１３１の前方に光を拡散する球体レンズ１２９を配置したので、第１ＬＥＤ群１３１の光の照射範囲を広げることができる。 Fifth, the present invention is characterized in that a spherical lens 129 that diffuses light is disposed in front of the first LED group 131.
Since the spherical lens 129 that diffuses light is arranged in front of the first LED group 131, the light irradiation range of the first LED group 131 can be expanded.

本発明は第６に、図４〜図６に示したように、一つの灯体ハウジングとしてのハウジング１０５内にロービーム用光源としてのアッパーＬＥＤ群９４と、ハイビーム用光源としてのロアＬＥＤ群９７を配置したヘッドランプ４７において、アッパーＬＥＤ群９４とロアＬＥＤ群９７とを隔壁としての境界壁１２１により区画するとともに、その境界壁２１をハーフミラーで構成したことを特徴とする。   As shown in FIGS. 4 to 6, the present invention sixthly includes an upper LED group 94 as a low beam light source and a lower LED group 97 as a high beam light source in a housing 105 as one lamp housing. In the arranged headlamp 47, the upper LED group 94 and the lower LED group 97 are partitioned by a boundary wall 121 as a partition wall, and the boundary wall 21 is configured by a half mirror.

これにより、アッパーＬＥＤ群９４及びロアＬＥＤ群９７の一方を点灯したときに、境界壁１２１を通してアッパーＬＥＤ群９４及びロアＬＥＤ群９７の他方に光を供給することができ、アッパーＬＥＤ群９４及びロアＬＥＤ群９７の両方が光って見え、ヘッドランプ４７の遠方からの視認性を向上させることができる。   Thus, when one of the upper LED group 94 and the lower LED group 97 is lit, light can be supplied to the other of the upper LED group 94 and the lower LED group 97 through the boundary wall 121, and the upper LED group 94 and the lower LED group 97 can be supplied. Both LED groups 97 appear to shine, and the visibility of the headlamp 47 from a distance can be improved.

本発明は第７に、図３及び図４に示したように、アッパーＬＥＤ群９４の光を反射するアッパーリフレクタ９５を正面視でほぼ円形にするとともに、ロアＬＥＤ群９７の光を反射するロアリフレクタ９８，９９を正面視でアッパーリフレクタ９５に沿うように細長く形成し、ロアＬＥＤ群９７をロアリフレクタ９８，９９の前方に配置するとともにロアリフレクタ９８，９９に向くようにしたことを特徴とする。   Seventhly, according to the present invention, as shown in FIGS. 3 and 4, the upper reflector 95 that reflects the light of the upper LED group 94 is substantially circular in front view, and the lower reflector that reflects the light of the lower LED group 97.

これにより、アッパーリフレクタ９５とロアリフレクタ９８，９９との一体感を高めることができ、また、ハイビーム用ランプ９２では、ロアリフレクタ９８，９９のみによる反射光の制御を行うことができ、反射光の制御が容易になる。   As a result, the sense of unity between the upper reflector 95 and the lower reflectors 98 and 99 can be enhanced, and the high beam lamp 92 can control the reflected light only by the lower reflectors 98 and 99. Control becomes easy.

尚、本発明では、ロービーム用光源の光を反射するリフレクタを正面視でほぼ円形にしたが、これに限らず、横長の楕円、横長の長円、あるいはこれらに類似する形状にしてもよい。   In the present invention, the reflector that reflects the light of the low beam light source is substantially circular when viewed from the front.
