本発明は、照明器具に関するものである。 The present invention relates to a lighting fixture.
従来より、ＬＥＤ光源を用いた外灯が知られている（例えば、特許文献１参照）。 Conventionally, an outdoor lamp using an LED light source is known (see, for example, Patent Document 1).
特許文献１に記載の防犯灯は、屋外に立設された電柱等の上部に取り付けられ、下方の路面等を照明するものであり、光源部と、この光源部を収納する防犯灯本体とを有する。 The security light described in Patent Document 1 is attached to the upper part of an electric pole or the like standing outdoors, and illuminates the road surface below. A light source part and a security light body that houses the light source part are provided. Have.
防犯灯には、光源部として、複数の少なくとも３つのＬＥＤユニットが取り付けられている。また、防犯灯本体における光源部の前方には、光透過性のグローブが取り付けられている。 A plurality of at least three LED units are attached to the security light as a light source unit. In addition, a light-transmitting glove is attached in front of the light source unit in the security light main body.
しかしながら、前述した防犯灯は、ＬＥＤユニットやＬＥＤ光源が、グローブや透光性パネルに近接した位置において、透光性パネルに略垂直に照射するように設けられている。 However, the security light described above is provided so that the LED unit and the LED light source irradiate the translucent panel substantially perpendicularly at a position close to the globe or the translucent panel.
このため、ＬＥＤ光源と透光性パネルとの間の距離が短く、透光性パネルにＬＥＤ光源のイメージが強く表れるという問題があった。 For this reason, there existed a problem that the distance between an LED light source and a translucent panel was short, and the image of the LED light source appeared strongly on the translucent panel.
また、この問題を解決するために、従来よりＬＥＤ光源とパネル等との間に拡散性のパネルを設けることが行われているが、この場合には、コストアップおよび器具効率の低下を招くという問題がある。 In order to solve this problem, a diffusive panel is conventionally provided between the LED light source and the panel. In this case, the cost increases and the instrument efficiency decreases. There's a problem.

以下、本発明の実施形態について図１〜４を用いて説明する。 Hereinafter, embodiments of the present invention will be described with reference to FIGS.
図１に示すように、本発明に係る実施形態の照明器具１０は、路面１１等を照明する外灯に好適であり、支柱５０の上部に設けられた灯具２０を有する。 As shown in FIG. 1, the luminaire 10 according to the embodiment of the present invention is suitable for an external lamp that illuminates a road surface 11 and the like, and includes a lamp 20 provided on an upper portion of a column 50.
また、図２には、本発明に係る灯具２０の断面図を示している。なお、図２は、灯具２０の側面の外観が視認できるように、右半分は灯具２０の断面図、左半分は灯具２０の側面図を表している。 Moreover, in FIG. 2, sectional drawing of the lamp 20 which concerns on this invention is shown. In FIG. 2, the right half represents a cross-sectional view of the lamp 20 and the left half represents a side view of the lamp 20 so that the appearance of the side of the lamp 20 can be visually recognized.
図２に示す通り、灯具２０は、灯具２０の略中心付近に複数のＬＥＤ光源２５を有している。また、灯具２０は、上方が開口し、ＬＥＤ光源２５を囲うように側面に透光パネル部２２と縦枠部２４が周方向に交互に並ぶ筒状の外周壁部２７を有する灯具本体２１と、灯具本体２１の開口を覆う着脱可能な蓋部２３とを有する。 As shown in FIG. 2, the lamp 20 has a plurality of LED light sources 25 near the approximate center of the lamp 20. In addition, the lamp 20 has an upper opening, and a lamp body 21 having a cylindrical outer peripheral wall portion 27 in which a translucent panel portion 22 and a vertical frame portion 24 are alternately arranged in the circumferential direction on a side surface so as to surround the LED light source 25. And a detachable lid portion 23 that covers the opening of the lamp body 21.
蓋部２３を取外し可能とすることで、ＬＥＤ光源２５の交換、また灯具本体２１の内部清掃が容易に行うことが可能である。このように蓋部２３を灯具本体２１から取り外した際に蓋部２３が落下しないように、落下防止ワイヤー２８が備えられている。 By making it possible to remove the lid 23, it is possible to easily replace the LED light source 25 and clean the interior of the lamp body 21. Thus, the fall prevention wire 28 is provided so that the lid 23 will not fall when the lid 23 is removed from the lamp body 21.
透光パネル部２２は、図２では平板形状であるが、平板に限られず曲面形状であってもよい。照明器具１０の美観設計に合わせて曲面もしくは平板形状のいずれかを選択することが可能である。 Although the translucent panel part 22 is flat plate shape in FIG. 2, it is not restricted to a flat plate, A curved surface shape may be sufficient. Either a curved surface or a flat plate shape can be selected according to the aesthetic design of the lighting fixture 10.
また、ＬＥＤ光源２５に電力を供給する電線４０は、路面１１から支柱５０の内部空間を通って灯具２０に配線され、ＬＥＤ光源２５に接続される。なお、ＬＥＤ光源２５を点灯させるための電源装置（図示せず）は、灯具本体２１の下部や、光源取付板２６の上部等に設けることができる。 Further, the electric wire 40 that supplies power to the LED light source 25 is wired from the road surface 11 through the internal space of the support column 50 to the lamp 20 and connected to the LED light source 25. A power supply device (not shown) for turning on the LED light source 25 can be provided in the lower part of the lamp body 21, the upper part of the light source mounting plate 26, or the like.
また、灯具２０は、支柱５０から取外し可能な構造となっている。支柱５０と灯具２０はボルト６０によって固定されており、灯具２０と支柱５０は落下防止ワイヤー２８によって接続されており、万一、支柱５０から灯具２０が外れても灯具２０が路面１１に落下することは防ぐことが可能である。 In addition, the lamp 20 has a structure that can be detached from the column 50. The column 50 and the lamp 20 are fixed by a bolt 60, and the lamp 20 and the column 50 are connected by a fall prevention wire 28. Even if the lamp 20 is removed from the column 50, the lamp 20 falls on the road surface 11. This can be prevented.
続いて、ＬＥＤ光源２５の設置位置について説明する。図２に示す通り、ＬＥＤ光源２５は、灯具本体２１の開口に設けられている光源取付板２６に設置されている。また、図３に示す通り、設置方向に関しては、ＬＥＤ光源２５の光軸３０上に縦枠部２４がくるような方向に向けて設置されている。 Next, the installation position of the LED light source 25 will be described. As shown in FIG. 2, the LED light source 25 is installed on a light source mounting plate 26 provided in the opening of the lamp body 21. Further, as shown in FIG. 3, the installation direction is set so that the vertical frame portion 24 comes on the optical axis 30 of the LED light source 25.
ＬＥＤ光源２５の光軸３０上における照度が非常に強く、その照度が強い光軸３０上に縦枠部２４を設けることで、透光パネル部２２上にランプイメージを映し出さないようにすることが可能となる。 The illumination intensity on the optical axis 30 of the LED light source 25 is very strong. By providing the vertical frame portion 24 on the optical axis 30 where the illumination intensity is strong, it is possible to prevent the lamp image from being projected on the translucent panel portion 22. It becomes possible.
このように、ＬＥＤ光源２５の光軸をどこに向けるかに工夫を加えることによって、ＬＥＤ光源２５と透光パネル部２２との間に拡散パネル等を設ける必要がなくなり、器具効率の低下およびコストアップを防ぐことが可能となる。 Thus, by devising where the optical axis of the LED light source 25 is directed, it is not necessary to provide a diffusion panel or the like between the LED light source 25 and the translucent panel unit 22, and the efficiency and cost of the apparatus are reduced. Can be prevented.
また、ＬＥＤ光源２５は、斜め下方向に向けて光を照射している。斜め下方向に照射することによって、ＬＥＤ光源２５から透光パネル部２２までの光路を長く保つことが可能であり、より一層、透光パネル部２２の表面にランプイメージが映し出されないようにすることが可能となる。 Further, the LED light source 25 irradiates light in a diagonally downward direction. By irradiating obliquely downward, the light path from the LED light source 25 to the translucent panel unit 22 can be kept long, and the lamp image is further prevented from being projected on the surface of the translucent panel unit 22. It becomes possible.
また、本実施形態の灯具本体２１の形状は、図２および図３に示す四角形状のものに限られるものではない。たとえば、図４（ａ）〜（ｄ）に示すように、透光パネル部２２を平面視多角形状に形成することも可能である。 Further, the shape of the lamp body 21 of the present embodiment is not limited to the rectangular shape shown in FIGS. For example, as shown in FIGS. 4A to 4D, the translucent panel portion 22 can be formed in a polygonal shape in plan view.
また、上記のように、透光パネル部２２を平面視多角形状に配置した際に、縦枠部２４を各角部位に設けることも可能である。縦枠部２４を各角部位に設けた際は、ＬＥＤ光源２５の光軸を平面視多角形状の各角部位に向けることで、上述と同じ効果を得ることが可能である。 Further, as described above, when the translucent panel portion 22 is arranged in a polygonal shape in plan view, the vertical frame portion 24 can be provided at each corner portion. When the vertical frame portion 24 is provided at each corner, the same effect as described above can be obtained by directing the optical axis of the LED light source 25 toward each corner of the polygonal shape in plan view.
さらに、上述している縦枠部２４の内側面を反射面とすることで、より照明効率のよい照明器具１０を提供することが可能である。反射面としては、内側面を白色で塗装するなど、また鏡面加工するなど様々な工法が考え得る。これら反射面の材質、工法に関しては、当業者であれば通常考え得るものであれば、何ら限定することなく用いることが可能である。 Furthermore, it is possible to provide the lighting fixture 10 with more efficient illumination by making the inner surface of the vertical frame part 24 mentioned above into a reflective surface. As the reflecting surface, various methods such as painting the inner surface in white or mirror finishing can be considered. With respect to the material and construction method of these reflecting surfaces, those skilled in the art can normally use them without limitation.
