Description

照明器具lighting equipment
　本発明は、道路や駐車場などの照明に使用する照明器具に関する。
The present invention relates to a lighting apparatus used for lighting a road or a parking lot.
　一般的に、道路や駐車場などの照明に使用する照明器具は、光源ランプと、この光源ランプからの光を路面や地面（以下、単に「地面」という。）に向けて反射する反射板とを備え、反射板としては、カップ状（ドーム状）のものが多用されている。 In general, a luminaire used for lighting such as a road or a parking lot includes a light source lamp and a reflector that reflects light from the light source lamp toward a road surface or the ground (hereinafter simply referred to as “the ground”). As a reflector, a cup-shaped (dome-shaped) plate is often used.

　従来、このような照明器具では、地面での照度確保や、グレアの抑制等の地面上の照明特性が主要な要求特性とされてきたが、近年、例えば道路灯の後方から道路の外側に隣接した住宅や田畑に漏れる光が、光公害として問題とされるようになってきており、このため、上述のような地面上における照明特性に加えて、照明すべき場所だけを的確に照明し、不要な光をできる限り低減する配光制御が求められるようになって来た。
Conventionally, in such luminaires, lighting characteristics on the ground such as securing illuminance on the ground and suppressing glare have been the main required characteristics, but in recent years, for example, adjacent to the outside of the road from the rear of the road lamp. The light that leaks into the houses and fields that have been used is becoming a problem as light pollution, and in addition to the above-mentioned lighting characteristics on the ground, only the place to be illuminated is accurately illuminated, Light distribution control that reduces unnecessary light as much as possible has been demanded.

　不要な光を低減する技術としては、特許文献１に開示されているように、反射板内に遮光板を配置する技術が知られている。しかし、遮光板を配置する技術では、本来、地面を照明するために使用されるべき光がカットされしまうので、地面に対する照明効率が悪くなるという問題がある。

特開２００３－３３８２１５号公報
As a technique for reducing unnecessary light, as disclosed in Patent Document 1, a technique in which a light shielding plate is arranged in a reflecting plate is known. However, in the technique of arranging the light shielding plate, the light that should be originally used for illuminating the ground is cut, so that there is a problem that the illumination efficiency with respect to the ground is deteriorated.

JP 2003-338215 A
　本発明が解決しようとする課題は、照明効率を悪化させることなく、照明すべき場所だけを的確に照明し、不要な光をできる限り低減することができる照明器具を提供することにある。
The problem to be solved by the present invention is to provide a luminaire that can accurately illuminate only a place to be illuminated and reduce unnecessary light as much as possible without deteriorating illumination efficiency.
　本発明は、反射板と、この反射板の内部に配置される光源ランプとを有する照明器具であって、反射板は、複数の平面の組み合わせにより形成されるとともに、光源ランプの前方に配置される前部反射部と、光源ランプの後方に配置される後部反射部と、光源ランプの上方に配置される上部反射部と、光源ランプの側方に配置される側部反射部とを備え、前部反射部及び後部反射部が、いずれも前方に向かって傾斜しているものである。 The present invention is a luminaire having a reflector and a light source lamp disposed inside the reflector, and the reflector is formed by a combination of a plurality of planes and is disposed in front of the light source lamp. A front reflector, a rear reflector disposed behind the light source lamp, an upper reflector disposed above the light source lamp, and a side reflector disposed on the side of the light source lamp, Both the front reflection part and the rear reflection part are inclined forward.

　このように、本発明では、光源ランプの後方に配置される後部反射部を前方に向かって傾斜させており、光源ランプの後方に向かう光を後部反射部によって前方に反射させることができるので、光源ランプの後方への不要な光を大幅に低減でき、前方の照明すべき場所だけを的確に照明することができる。すなわち、本発明では、不要な光を低減するために、上記特許文献１のように遮光板を用いるのではなく、後部反射部によってその反射方向を制御（配光制御）するので、照明効率が悪くなることはない。
As described above, in the present invention, the rear reflecting portion disposed behind the light source lamp is inclined forward, and the light toward the rear of the light source lamp can be reflected forward by the rear reflecting portion. Unnecessary light behind the light source lamp can be greatly reduced, and only the front illumination area can be illuminated accurately. That is, in the present invention, in order to reduce unnecessary light, the light reflection plate is not used as in Patent Document 1 but the reflection direction is controlled (light distribution control) by the rear reflector, so that the illumination efficiency is high. It won't get worse.

　本発明において、照明する前方の具体的な範囲は、前部反射部及び後部反射部の形状、傾斜角度等の調整によって制御する。また、照明する側方の具体的な範囲は、上部反射部及び対向する側部反射部の形状、傾斜角度等の調整によって制御する。本発明では、反射板は、「曲面」ではなく複数の「平面」の組み合わせにより形成されていることから、反射板の「平面」によって反射された光は強い指向性を有し、減衰しにくく遠方まで到達する。さらに、複数の「平面」によって反射させることで、光の反射方向を精緻に制御することができ、照明すべき場所だけを的確に照明することができる。
In the present invention, the specific range in front of the illumination is controlled by adjusting the shapes, inclination angles, etc. of the front and rear reflection parts. Moreover, the specific range of the side to illuminate is controlled by adjustment of the shape, inclination angle, etc. of an upper reflection part and the opposing side reflection part. In the present invention, since the reflecting plate is formed not by a “curved surface” but by a combination of a plurality of “planes”, the light reflected by the “plane” of the reflecting plate has a strong directivity and is not easily attenuated. Reach far away. Furthermore, by reflecting with a plurality of “planes”, the reflection direction of light can be precisely controlled, and only the place to be illuminated can be illuminated accurately.

　このように平面の組み合わせからなる反射板の各反射部は、平板又はその折り曲げ加工により形成することができる。反射板をこのような構成とすることで、より簡単に反射板を製作でき、コストダウンを図ることができる。
Thus, each reflection part of the reflecting plate which consists of a plane combination can be formed by a flat plate or its bending process. By configuring the reflecting plate in such a configuration, the reflecting plate can be manufactured more easily and the cost can be reduced.

　また、より強い光を得たい場合には各反射部を鏡面加工し、軟らかい光を得たい場合には梨地加工又はエンボス加工をする。
Further, when it is desired to obtain a stronger light, each reflecting portion is mirror-finished, and when it is desired to obtain a soft light, a satin finish or an embossing is performed.

　さらに、本発明において光源ランプは、後部反射部に設けた開口部から反射板内に挿入し、略水平に配置することができるし、上部反射部に設けた開口部から反射板内に挿入し、前部反射部及び後部反射部の傾斜方向と略平行に配置することもできる。このうち、後者の配置とすると、光源ランプの後方の光を後部反射部によって、より確実に反射させることができ、照明効率が向上する。
Further, in the present invention, the light source lamp can be inserted into the reflecting plate from the opening provided in the rear reflecting portion, and can be disposed substantially horizontally, or can be inserted into the reflecting plate from the opening provided in the upper reflecting portion. In addition, the front reflection part and the rear reflection part can be arranged substantially parallel to the inclination direction. Among these, if it is the latter arrangement | positioning, the light behind a light source lamp can be more reliably reflected by a rear part reflection part, and illumination efficiency improves.

　また、本発明においては、対向する側部反射部どうしの間に、反射板の内部からの光を反射板の内部に向けて反射する補助反射板が配置することができる。このような補助反射板を配置することで、所定の照明範囲内において、光の強度分布を制御することが可能となる。
Moreover, in this invention, the auxiliary | assistant reflecting plate which reflects the light from the inside of a reflecting plate toward the inside of a reflecting plate can be arrange | positioned between the opposing side part reflection parts. By disposing such an auxiliary reflector, it is possible to control the light intensity distribution within a predetermined illumination range.
　本発明の照明器具によれば、照明効率を悪化させることなく、照明すべき場所だけを的確に照明し、不要な光を大幅に低減することができる。 According to the lighting fixture of the present invention, it is possible to accurately illuminate only the place to be illuminated without deteriorating the illumination efficiency, and to significantly reduce unnecessary light.

　すなわち、本発明では、光源ランプの後方に向かう光を後部反射部によって前方に反射させるので、照明効率が悪くなることはなく、むしろ光源ランプの後方に向かう光も前方を照明するために使用できるので、従来の単純なカップ状（ドーム状）の反射板を使用した照明器具に比べ、前方の照明効率は向上する。したがって、従来より、照明器具の設置数を削減、あるいは光源ランプの出力（ワット数）を小さくでき、省エネルギーを図ることができる。
That is, in the present invention, the light directed toward the rear of the light source lamp is reflected forward by the rear reflector, so that the illumination efficiency is not deteriorated, but the light directed toward the rear of the light source lamp can be used to illuminate the front. Therefore, the front illumination efficiency is improved as compared with a conventional luminaire using a simple cup-shaped (dome-shaped) reflector. Therefore, conventionally, the number of luminaires can be reduced, or the output (wattage) of the light source lamp can be reduced to save energy.

Further, the side reflecting portion 14 is formed in a shape along an arcuate curved surface in which one flat plate is sequentially bent, is inclined toward the side as a whole, and has a convex side.

Further, between the opposing side reflecting portions 14, 14 of the reflecting plate 10, the auxiliary reflecting plate 20 that reflects light from the inside of the reflecting plate 10 toward the inner rear side of the reflecting plate 10 over the entire length thereof. Is arranged.

　光源ランプ３０は、後部反射部１２に設けた開口部１５から反射板１０内に挿入されて、略水平に配置されている。光源ランプ２０の一端は、照明器具本体４０に設けたソケット４１に装着されている。また、反射板１０も照明器具本体４０に支持されている。
The light source lamp 30 is inserted into the reflector 10 from the opening 15 provided in the rear reflector 12 and is arranged substantially horizontally. One end of the light source lamp 20 is attached to a socket 41 provided in the lighting fixture body 40. The reflector 10 is also supported by the lighting fixture body 40.

　以上の構成において、光源ランプ３０から後方に向かう光は、前方に向かって傾斜する後部反射部１２によって前方に反射される。したがって、光源ランプ３０の後方への不要な光を大幅に低減できる。また、前方に向かう光は、一部はそのまま直進し、また他の一部は前方に向かって傾斜する前部反射部１１によって斜め下方に反射される。したがって、前部反射部１１及び後部反射部１２の形状及び傾斜角度等の調整によって、その前後方向の照明範囲を制御することができる。例えば、本実施例の照明器具を道路の路肩に配置すれば、道路の外側への不要な光を大幅に低減でき、道路の幅員方向の照明すべき場所だけを的確に照明することができる。
In the above configuration, the light traveling backward from the light source lamp 30 is reflected forward by the rear reflecting portion 12 inclined forward. Therefore, unnecessary light behind the light source lamp 30 can be greatly reduced. Further, a part of the light traveling forward travels straight as it is, and the other part is reflected obliquely downward by the front reflector 11 that inclines forward. Therefore, the illumination range in the front-rear direction can be controlled by adjusting the shapes and inclination angles of the front reflector 11 and the rear reflector 12. For example, if the lighting fixture of the present embodiment is arranged on the shoulder of a road, unnecessary light to the outside of the road can be greatly reduced, and only the place to be illuminated in the width direction of the road can be illuminated accurately.

　また、光源ランプ３０から上方に向かう光は、ジグザグ状に形成された上部反射部１３によって、その大部分が側部傾斜部１４に向かって反射され、さらに側部傾斜部１４によって反射されることによって、側方に大きく拡がる。また、光源ランプ３０から側方に向かう光も側部傾斜部１４によって反射され、側方に拡がる。このように、ジグザグ状の上部反射部１３と多段平面状の側方反射部１４との組み合わせによって、側方向の広い範囲を照明することができ、さらに、上部反射部１３及び側部反射部１４の形状、傾斜角度等の調整によって、照明すべき範囲を制御できる。したがって、本実施例の照明器具を道路の路肩に配置すれば、道路の走行方向に沿って広い範囲を照明することができ、その設置間隔を広くでき、結果として設置数を削減できる。
Further, most of the upward light from the light source lamp 30 is reflected toward the side inclined portion 14 by the upper reflecting portion 13 formed in a zigzag shape, and further reflected by the side inclined portion 14. Will greatly expand to the side. Moreover, the light which goes to the side from the light source lamp 30 is reflected by the side part inclination part 14, and spreads to the side. In this way, a wide range in the lateral direction can be illuminated by the combination of the zigzag upper reflecting portion 13 and the multi-level planar side reflecting portion 14, and further, the upper reflecting portion 13 and the side reflecting portion 14 can be illuminated. The range to be illuminated can be controlled by adjusting the shape, inclination angle, and the like. Therefore, if the lighting apparatus of the present embodiment is arranged on the shoulder of the road, a wide range can be illuminated along the road traveling direction, the installation interval can be widened, and the number of installations can be reduced as a result.

　さらに、本実施例では上述のとおり、補助反射板２０を設け、反射板１０の内部からの光を反射板１０の内部後方に向けて反射するようにしている。これによって、前方を照明しようとする光が補助反射板２０によって反射板１０の内部後方に向けて反射され、照明器具の下方を照明する光として振り替えられるので、照明器具下方の光の強度（照度）をより高くすることができる。この照明器具下方の照度の強化の程度は、補助反射板２０の傾斜角度θ（図１参照）を変更することにより制御できる。
Furthermore, in this embodiment, as described above, the auxiliary reflector 20 is provided so that the light from the inside of the reflector 10 is reflected toward the inside rear of the reflector 10. As a result, the light to illuminate the front is reflected by the auxiliary reflector 20 toward the inner rear of the reflector 10 and is redirected as light that illuminates the lower part of the luminaire. ) Can be made higher. The degree of illuminance enhancement below the lighting fixture can be controlled by changing the inclination angle θ (see FIG. 1) of the auxiliary reflector 20.

　なお、照明器具下方の照度を強化する必要がない場合は、補助反射板２０を設ける必要はない。また、図１の実施例とは逆に照明器具前方の照度を強化したい場合には、補助反射板２０を図１と対称に設けて、反射板１０の内部からの光を反射板１０の内部前方に向けて反射させるようにすることもできる。
In addition, when it is not necessary to strengthen the illuminance below the lighting fixture, it is not necessary to provide the auxiliary reflector 20. In contrast to the embodiment of FIG. 1, when it is desired to enhance the illuminance in front of the luminaire, the auxiliary reflector 20 is provided symmetrically with FIG. 1, and light from the inside of the reflector 10 is transmitted to the interior of the reflector 10. It can also be made to reflect forward.
