一般にＬＥＤ素子は、消費電力が少なく寿命も長いことから、蛍光灯に代わって街路灯として使用することのメリットは大きいと云えるが、街路灯としての明るさを得るためには多数個のＬＥＤ素子を設ける必要があり、そのために従来では、図８に示したように、取付基板ａを適宜角度の折板状に形成し、複数個のＬＥＤ素子ｂが実装された配線基板ｃを該取付基板ａの前面にスペーサｄを介してビスｅにより固着する構造が採られていた。
また、下記特許文献１は、複数個のＬＥＤ素子を可撓性の基板に所定間隔で取付けることにより、該ＬＥＤ素子を任意の形状に配置できるようにした照明装置を開示するものである。
特開２００５−２２２９０３号公報 In general, LED elements consume less power and have a long life, so it can be said that the advantage of using as a street light instead of a fluorescent lamp is great, but in order to obtain the brightness as a street light, a large number of LEDs are used. Therefore, conventionally, as shown in FIG. 8, the mounting substrate a is formed in a folded plate shape with an appropriate angle, and a wiring substrate c on which a plurality of LED elements b are mounted is attached. A structure is adopted in which the front surface of the substrate a is fixed by screws e via spacers d.
Patent Document 1 below discloses a lighting device in which a plurality of LED elements are attached to a flexible substrate at predetermined intervals so that the LED elements can be arranged in an arbitrary shape.
JP 2005-222903 A

ところで、上記図８に示した構造では、配線基板ｃの取付，組立に手間が掛かるという問題があると共に、取付基板ａは容易には変形できないので、例えば街路灯設置現場の状況に合わせて個々の配線基板ｃのＬＥＤ素子ｂの照射方向を微調整するようなことができないものであった。また、ＬＥＤ素子ｂ等の発熱により配線基板ｃが高温度になることがあるが、上記構造では該配線基板ｃが取付基板ａから離間しているので放熱が効率的になされないという問題があった。
また、特許文献１に示された可撓性の基板では、取付後にもＬＥＤ素子が無用に動いてしまうおそれがある。
本発明はこのような課題を解決しようとするものである。 By the way, in the structure shown in FIG. 8, there is a problem that it takes time to mount and assemble the wiring board c, and the mounting board a cannot be easily deformed. The irradiation direction of the LED element b of the wiring board c cannot be finely adjusted. Moreover, although the wiring board c may become high temperature due to heat generated by the LED element b or the like, the above structure has a problem in that heat radiation is not efficiently performed because the wiring board c is separated from the mounting board a. It was.
Moreover, in the flexible board | substrate shown by patent document 1, there exists a possibility that an LED element may move uselessly after attachment.
The present invention is intended to solve such problems.

そのために請求項１に記載したＬＥＤ照明灯は、アルミニウムを押出成形することにより断面形状が略コ字状の等断面に成形された型材からなる長手部材は、前面に凹窪部と該凹窪部に隣接する縦溝が形成され、一方の側縁に丸軸状ジョイント部が一体に形成され、他方の側縁に切欠環状ジョイント部が一体に形成され、該ジョイント丸軸状部と該切欠環状ジョイント部の内側に一対の溝状レール部が相対するように形成され、該長手部材と同形のものをハウジング内に複数枚並列状に配置し、該長手部材の丸軸状ジョイント部を隣り合う長手部材の切欠環状ジョイント部を遊嵌することにより、該各長手部材を隣り合うものどうし屈折可能に連結し、前面にＬＥＤ素子が実装され裏面に電線コネクタが突設された配線基板を前記長手部材の一端から前記溝状レール部中にスライドさせることにより該配線基板を該長手部材の前面に装着し、前記電線コネクタを前記凹窪部に収納するとともに、該配線基板に貫挿したビスを前記縦溝に螺入することにより、複数枚の該配線基板が該長手部材の長手方向に所望間隔で止着されるようにしたことを特徴とする。 For this purpose, the LED illumination lamp according to claim 1 has a longitudinal member made of a mold formed into an equal cross-section having a substantially U-shaped cross-section by extruding aluminum.
