図３は、本発明に係わる車両用発光装置の、適用の一例を示すもので、車両用発光装置が取り付けられた車両の平面図である。車両Ｃはトラックであり、車両Ｃの荷台Ｃ１には積み荷Ｔが積載されている。車両用発光装置１０は車両Ｃの側端や後端、積み荷Ｔに直接取り付けてもよいが、本実施形態に示す如く積み荷Ｔのはみ出し部Ｔ１に取り付けてはみ出した積み荷Ｔの存在を喚起することで更に高い注意喚起の効果を得ることができる。はみ出し部Ｔ１には通常赤い布が取り付けられたりするが、赤い布のみでは当然夜間においては視認することができず、車両用発光装置１０を取り付けることで夜間においてもはみ出し部Ｔ１を視認させることができる。本図において、積み荷Ｔは横方向にはみ出し部Ｔ１が生じており、はみ出し部Ｔ１の側面各々に車両用発光装置１０が取り付けられることで、車両Ｃの前方及び後方に各々光Ｌ１及び光Ｌ２が放射されるようになされている。 FIG. 3 shows an example of application of the vehicle light emitting device according to the present invention, and is a plan view of the vehicle to which the vehicle light emitting device is attached. The vehicle C is a truck, and a load T is loaded on the loading platform C1 of the vehicle C. The vehicle light emitting device 10 may be directly attached to the side end or rear end of the vehicle C, or the load T. However, as shown in the present embodiment, the vehicle light emitting device 10 is attached to the protruding portion T1 of the load T to alert the existence of the protruding load T. With this, you can get a higher alerting effect. Usually, a red cloth is attached to the protruding portion T1, but it is naturally impossible to visually recognize the red cloth alone at night. it can. In this figure, the load T has a protruding portion T1 in the lateral direction, and the light emitting device 10 for the vehicle is attached to each of the side surfaces of the protruding portion T1, so that the light L1 and the light L2 are respectively forward and backward of the vehicle C. It is supposed to be emitted.
ここで車両用発光装置１０から放射される光Ｌ１及び光Ｌ２は、光Ｌ１が常時点灯として視認できるような光となされ、光Ｌ２が点滅発光するようになされている。光Ｌ１と光Ｌ２との発光のモードが異なるものとなされていることで、車両Ｃの前後が判りやすくなって進行方向を認識するのが容易となり、巻き込み等の発生を防止することに繋がるが、更に相反する方向に光Ｌ１と光Ｌ２とが車両の前方及び後方に向けて放射されていることで、前方に向けて放射された光Ｌ１は車両Ｃの運転台Ｃ２若しくはミラーＣ３に照射されて運転者が視認することで、はみ出し部Ｔ１を認識して狭道の通過時や旋回時にはみ出し部Ｔ１が衝突するのを防止することができる。また後方に向けて放射された光Ｌ２は、後方や側方を走行する他の車両の運転者に対してはみ出し部Ｔ１の存在を喚起することで、はみ出し部Ｔ１への接触等の発生を未然に防止することができる。 Here, the light L1 and the light L2 emitted from the vehicle light-emitting device 10 are light that allows the light L1 to be visually recognized as being always on, and the light L2 flashes and emits light. Since the light emission modes of the light L1 and the light L2 are different from each other, the front and rear of the vehicle C can be easily understood and the traveling direction can be easily recognized, which can prevent the occurrence of entrainment or the like. Further, since the light L1 and the light L2 are emitted toward the front and the rear of the vehicle in opposite directions, the light L1 emitted toward the front is applied to the cab C2 or the mirror C3 of the vehicle C. By visually recognizing the driver, it is possible to recognize the protrusion T1 and prevent the protrusion T1 from colliding when passing through a narrow path or turning. Further, the light L2 radiated rearward urges the driver of another vehicle traveling rearward or laterally to cause the presence of the protruding portion T1, thereby causing the occurrence of contact to the protruding portion T1 and the like. Can be prevented.
更に、運転台Ｃ２若しくはミラーＣ３に照射される光Ｌ１を常時点灯として視認できるような光Ｌ１とし、後方への光Ｌ２が点滅発光としていることで、車両Ｃの運転者に対しては発光が目障りなものとならず、後方又は側方を走行する他の車両の運転者に対しては点滅により注意喚起の効果を高めることができるようになされている。 Furthermore, the light L1 irradiated to the driver's cab C2 or the mirror C3 is changed to the light L1 that can be visually recognized as being always lit, and the backward light L2 is flashing to emit light so that the driver of the vehicle C can emit light. The effect of alerting the driver of other vehicles traveling rearward or sideways is enhanced by blinking without being obtrusive.
発光体３を常時点灯として視認できるようにするには、連続して電力供給を行うことで発光させるようにしてもよく、デューティ比を高めの状態として点滅させることで肉眼では常時点灯しているように見せることで発光に係わる電力の消費量を低減するようにしてもよい。 In order to make the illuminant 3 visible at all times, it may be made to emit light by continuously supplying power, and it is always lit by the naked eye by blinking as a high duty ratio. By making it look like this, you may make it reduce the power consumption regarding light emission.
図４は、本発明に係わる車両用発光装置の、適用の他の例を示すもので、車両用発光装置が取り付けられた車両の平面図である。車両Ｃは図３に示したものと同様にトラックであり、荷台Ｃ１に積み荷Ｔが積載されているが、積み荷Ｔは荷台Ｃ１の後方にはみ出してはみ出し部Ｔ１が生じている。かかるはみ出し部Ｔ１に車両用発光装置１０を取り付けておくことで、後方を走行する車両の運転者や、車両Ｃが停車時にその周辺を通行する歩行者がはみ出し部Ｔ１を認識して衝突や接触による事故を未然に防止することができる。 FIG. 4 shows another example of application of the vehicle light emitting device according to the present invention, and is a plan view of the vehicle to which the vehicle light emitting device is attached. The vehicle C is a truck similar to that shown in FIG. 3, and a load T is loaded on the loading platform C1, but the loading T protrudes to the rear of the loading platform C1 to generate an overhanging portion T1. By attaching the light emitting device 10 for the vehicle to the protruding portion T1, a driver of a vehicle traveling behind or a pedestrian passing through the periphery of the vehicle C when the vehicle C stops recognizes the protruding portion T1 and collides or makes contact. Accidents caused by can be prevented in advance.
