Description

本発明は、車両用灯具に関するものであり、更に詳しくは、乗用車、トラック等の自動車、自動二輪車、自転車、電車等の車両に装備されるテールランプ、ブレーキランプ（ストップランプ）等の車両用灯具に係るものである。   The present invention relates to a vehicular lamp, and more specifically, to a vehicular lamp such as a tail lamp and a brake lamp (stop lamp) that are mounted on a vehicle such as a passenger car and a truck, a motorcycle, a bicycle, and a train. It is concerned.

車両用灯具としては、例えば図９に示すように、保持体１に複数の発光ダイオード（ＬＥＤ）３、３・・・を取り付けてなるものが既に知られている。   As a vehicular lamp, for example, as shown in FIG. 9, a lamp in which a plurality of light emitting diodes (LEDs) 3, 3.

また、実開平６−１０８８０号公報は、平板状の基板に複数の発光ダイオードを取り付けてなる車両用灯具を開示している。   Japanese Utility Model Laid-Open No. 6-10880 discloses a vehicular lamp in which a plurality of light emitting diodes are attached to a flat substrate.

発光ダイオードは、白熱電球に比べて、点灯信号を受けてから実際に点灯するまでに要する時間がはるかに短い。即ち、この時間は、例えば、白熱電球が約０．３秒であるのに対し、発光ダイオードが約０．００２秒である。   Compared with incandescent light bulbs, light emitting diodes require a much shorter time from receiving a lighting signal until actually turning on. That is, this time is, for example, about 0.3 seconds for incandescent bulbs and about 0.002 seconds for light emitting diodes.

例えば、発光ダイオードをブレーキランプの発光体として使用した場合には、前車がブレーキを作動させてブレーキランプに点灯信号を送ってから前車のブレーキランプが実際に点灯するまでの時間は、白熱電球をブレーキランプの発光体として使用した場合に比べて、極めて短い。   For example, when a light-emitting diode is used as the light emitter of a brake lamp, the time from when the front vehicle activates the brake and sends a lighting signal to the brake lamp until the front vehicle brake light actually lights up is incandescent. Compared to the case where a light bulb is used as a light emitter of a brake lamp, it is extremely short.

従って、発光ダイオードをブレーキランプの発光体として使用した場合には、白熱電球をブレーキランプの発光体として使用した場合に比べて、後車の運転者は、前車のブレーキが作動したことを前車のブレーキランプを介してより早く視認することができる。即ち、発光ダイオードをブレーキランプの発光体として使用した場合には、前車のブレーキが作動してから後車がブレーキを作動させるまでの空走時間を短縮することにより、追突事故を防止し、或いは追突事故における人的、物的損害を軽減することができるという優れた効果が発揮される。 Therefore, when the light emitting diode is used as the light emitter of the brake lamp, the driver of the rear vehicle is more aware that the brake of the front vehicle has been activated than when the incandescent light bulb is used as the light emitter of the brake lamp. It can be seen more quickly through the brake light of the car. That is, when a light-emitting diode is used as a light emitter of a brake lamp, a rear-end collision is prevented by shortening the idle running time from when the brake of the front vehicle is operated until the rear vehicle is operated. Or the outstanding effect that the human and physical damage in a rear-end collision can be reduced is exhibited.

また、発光ダイオードは、白熱電球に比べて、消費電力が小さいという効果も有する。
実開平６−１０８８０号公報 In addition, the light emitting diode has an effect that power consumption is smaller than that of the incandescent bulb.
Japanese Utility Model Publication No. 6-10880

しかして、各発光ダイオードは、白熱電球に比べて、光照射範囲角度が極めて小さい。   Thus, each light-emitting diode has an extremely small light irradiation range angle as compared with an incandescent bulb.

光照射角度範囲とは、光を照射する範囲の角度をいうものとする。   The light irradiation angle range refers to the angle of the light irradiation range.

図９に示す上記車両用灯具及び実開平６−１０８８０号公報に示す車両用灯具（以下、これらのものを「従来の車両用灯具」という。）においては、複数の発光ダイオードが保持体の前面に平面状に配設されているため、これら発光ダイオード群の光照射範囲角度（図９における符号ａ参照）も小さい。   In the vehicle lamp shown in FIG. 9 and the vehicle lamp shown in Japanese Utility Model Laid-Open No. 6-10880 (hereinafter referred to as “conventional vehicle lamp”), a plurality of light emitting diodes are provided on the front surface of the holder. Therefore, the light irradiation range angle of these light emitting diode groups (see symbol a in FIG. 9) is also small.

しかも、従来の車両用灯具においては、複数の発光ダイオードが保持体の前面に平面状に配設されているため、リフレクターに発光ダイオードの光を反射させることにより車両用灯具の光照射範囲角度を大きくすることもできない。   Moreover, in the conventional vehicular lamp, a plurality of light emitting diodes are arranged in a plane on the front surface of the holding body, so that the light irradiation range angle of the vehicular lamp can be increased by reflecting the light of the light emitting diodes on the reflector. You can't make it bigger.

従って、従来の車両用灯具においては、光照射角度範囲が極めて小さく、当該光照射角度範囲の外側では車両用灯具の光を視認し難いという問題がある。   Therefore, the conventional vehicle lamp has a problem that the light irradiation angle range is extremely small, and it is difficult to visually recognize the light from the vehicle lamp outside the light irradiation angle range.

本発明は、従来の車両用灯具におけるこのような問題を解決すると共に、更に進んで、発光ダイオードの取付作業を容易にした車両用灯具を提供しようとしてなされたものである。   The present invention has been made to solve the above-mentioned problems in the conventional vehicular lamp, and further to provide a vehicular lamp that facilitates the mounting operation of the light emitting diode.

上記課題を解決するために、本発明は、下記の車両用灯具を提供する。   In order to solve the above problems, the present invention provides the following vehicular lamp.

（１）複数の発光ダイオードを立体的に配設したことを特徴とする車両用灯具（請求項１）。 (1) A vehicular lamp characterized in that a plurality of light emitting diodes are three-dimensionally arranged (claim 1).

（２）立体的な支持体の表面に支持孔を備えさせ、該支持孔に複数の発光ダイオードを立体的に支持させたことを特徴とする車両用灯具（請求項２）。 (2) A vehicular lamp characterized in that a support hole is provided on the surface of a three-dimensional support, and a plurality of light emitting diodes are three-dimensionally supported in the support hole (claim 2).

［請求項１の発明］
複数の発光ダイオードを立体的に配設したため、各発光ダイオードの光照射角度範囲は小さくても、発光ダイオード群全体の光照射角度範囲は極めて大きくなる。 [Invention of Claim 1]
Since the plurality of light emitting diodes are three-dimensionally arranged, even if the light irradiation angle range of each light emitting diode is small, the light irradiation angle range of the entire light emitting diode group becomes extremely large.

また、複数の発光ダイオードを立体的に配設したため、発光ダイオードの光をリフレクターに反射させることも容易である。   Further, since the plurality of light emitting diodes are three-dimensionally arranged, it is easy to reflect the light of the light emitting diodes to the reflector.

従って、車両用灯具の視認性は著しく向上する。   Therefore, the visibility of the vehicular lamp is significantly improved.

［請求項２の発明］
立体的な支持体の表面に支持孔を備えさせ、該支持孔に複数の発光ダイオードを立体的に支持させるようにしたため、発光ダイオードの脚を該支持孔に挿入することにより、複数の発光ダイオードを立体的に配設することができる。 [Invention of claim 2]
A support hole is provided on the surface of a three-dimensional support, and a plurality of light emitting diodes are three-dimensionally supported in the support hole. Can be arranged three-dimensionally.

従って、車両用灯具の組立作業は極めて容易である。 Therefore, the assembly operation of the vehicular lamp is extremely easy.

The light emitting diode group in this case has the same light irradiation angle range as the incandescent bulb.

複数の発光ダイオード１１、１１・・・を立体的に配設するために、好ましくは、立体的な支持体１３の表面に支持孔１５を備えさせ、該支持孔１５に複数の発光ダイオード１１、１１・・・を立体的に支持させる。   In order to three-dimensionally arrange the plurality of light-emitting diodes 11, 11..., Preferably, a support hole 15 is provided on the surface of the three-dimensional support 13, and the plurality of light-emitting diodes 11, 11 is supported three-dimensionally.

支持孔１５に発光ダイオード１１を支持させる際には、発光ダイオード１１の各脚１７を該支持孔１５に挿入し、適宜の接続手段１９により発光ダイオード１１の脚１７を接続する。   When the light emitting diode 11 is supported in the support hole 15, the legs 17 of the light emitting diode 11 are inserted into the support holes 15, and the legs 17 of the light emitting diode 11 are connected by appropriate connection means 19.

支持孔１５は、図５に示すように、連続した長溝状のものであってもよいが、図７に示すように、相互に連続していない独立した複数の孔よりなるものであっても差し支えない。   As shown in FIG. 5, the support hole 15 may have a continuous long groove shape, but as shown in FIG. 7, the support hole 15 may consist of a plurality of independent holes that are not continuous with each other.
