The capacitor and the substrate on which the LED is mounted are arranged rationally and compactly, and the size and weight are improved and the appearance is improved. The present invention relates to a construction lighting apparatus that is suitable for use and that can improve normal life and provide safe and stable normal lighting and emergency lighting.

工事用照明器具は、工事の種類や施工現場の状況によって種々のものが使用され、例えば道路工事用のものとして、透明な筒部に蛍光ランプを収容した筒状のケ−スと、このケ−スを立位状態で着脱可能に取付け、かつ電源に接続する固定台とを備えたものがある（例えば、特許文献１参照）。 Various lighting fixtures for construction are used depending on the type of construction and the situation at the construction site. For example, as a construction for road construction, a cylindrical case in which a fluorescent tube is accommodated in a transparent tubular portion, and this case. -There is one provided with a fixing base that is detachably mounted in a standing state and connected to a power source (for example, see Patent Document 1).

しかし、蛍光ランプは消費電力が大きく、大きな安定器を要して器具全体が大形重量化する上に概して寿命が短く、しかも停電時には蛍光ランプが消灯して作業が中断し、または困難になる等の問題があった。 However, the fluorescent lamp consumes a large amount of power, requires a large ballast, increases the overall weight of the apparatus, and generally has a short life. In addition, the fluorescent lamp is extinguished during a power failure, and the operation is interrupted or difficult. There was a problem such as.

このような問題を解決するものとして、器具本体の内部に反射板と蛍光ランプ、および前記ランプの光で発電する太陽電池とその蓄電体、該蓄電体によって点灯するＬＥＤからなる非常灯を備え、通常時は蛍光ランプを点灯してトンネル内を照明し、停電時に蓄電体の電力によって非常灯を点灯し、ランプの光を有効利用したトンネル照明装置がある（例えば、特許文献２参照）。 As a solution to such a problem, a reflection plate and a fluorescent lamp inside the instrument body, and a solar cell that generates power with the light of the lamp and its electric storage, an emergency light consisting of an LED that is lit by the electric storage, There is a tunnel lighting device that normally lights a fluorescent lamp to illuminate the inside of a tunnel during normal power outage, lights an emergency lamp with electric power of a power storage unit at the time of a power failure, and effectively uses light from the lamp (for example, see Patent Document 2).

しかし、前記照明装置は、大形大重量で広い設置スペ−スを要するとともに、非常灯の光量が概して低く、誘導灯としての十分な効果を得難く、しかも蛍光ランプや非常灯、蓄電体等を通常照明と同様に取付けているため、塵埃が発生し振動が激しいトンネル築造時下での使用には堪えられない。 However, the lighting device is large and heavy and requires a large installation space, and the amount of emergency light is generally low, and it is difficult to obtain a sufficient effect as a guide light. Moreover, a fluorescent lamp, emergency light, power storage unit, etc. Since it is installed in the same way as normal lighting, it is unbearable for use under the construction of tunnels where dust is generated and vibration is severe.

また、他の照明装置の中に、居住空間の天井部にＬＥＤ照明装置を設置し、該照明装置は中空の矩形断面からなる長尺の灯部を有し、該灯部を凹状に成形したアルミニウム製のシャ−シと、該シャ−シに連結するコ字形断面の乳白色の拡散カバ−とで構成し、前記シャ−シの内側に複数のプリント基板を短冊状に配置し、該基板の表面に複数のＬＥＤを実装し、前記灯部の両側をサイドカバ−で閉塞して、通常時は外部電力によって前記ＬＥＤを点灯し、停電等の非常時に、灯部の外側に設けたバッテリユニットから給電して前記ＬＥＤを点灯し、非常灯として機能させるようにしたものがある（例えば、特許文献３参照）。 In addition, among other lighting devices, an LED lighting device is installed on the ceiling portion of the living space, the lighting device has a long lamp portion having a hollow rectangular cross section, and the lamp portion is formed into a concave shape. An aluminum chassis and a milky white diffusion cover having a U-shaped cross section connected to the chassis, and a plurality of printed circuit boards are arranged in a strip shape inside the chassis. A plurality of LEDs are mounted on the surface, both sides of the lamp unit are closed with side covers, and the LEDs are normally lit by external power, and in an emergency such as a power failure, a battery unit provided outside the lamp unit There is one in which the LED is turned on by supplying power so as to function as an emergency light (for example, see Patent Document 3).

しかし、前記ＬＥＤ照明装置は、長尺で大形重量化する上に、周囲の照度等を検出する種々のセンサと、該センサの入力信号を処理するマイコンユニットを要し、また灯部の外側にバッテリユニットや充電器を配置しているため、構成の複雑化と大形重量化を助長し、高価になるとともに、多数のＬＥＤをシャ−シに実装したまま使用するため、設置環境が厳しい工事現場の使用に堪えられないという問題があった。 However, the LED lighting device is long and large in weight, requires various sensors for detecting ambient illuminance and the like, and a microcomputer unit for processing an input signal of the sensor. Since the battery unit and charger are installed in the unit, the configuration is complicated and the weight is increased, the cost is increased, and a large number of LEDs are mounted on the chassis, so the installation environment is severe. There was a problem of being unbearable for using the construction site.

前記挟持片６０，６０の中間部は凹状に湾曲形成され、その凹状湾曲部６０ｂ，６０ｂの内面に蓄電器５１の周面を挟持可能にしている。 An inner holder 59 is integrally formed inside the substrate holder 7, and the inner holder 59 is provided with a pair of holding pieces 60, 60 having elasticity on the lower inner surface of the substrate holder 7 so as to face each other. .
An intermediate portion of the sandwiching pieces 60, 60 is formed in a concave shape so that the peripheral surface of the battery 51 can be sandwiched between the inner surfaces of the concave curved portions 60b, 60b.

前記挟持片６０，６０の上端部は外側に屈曲され、該屈曲部６０ａの基部外周に係止溝６２が形成されている。
前記係止溝６２にＯリング、輪ゴム等の環状の掛止部材６３が装着され、その弾性によって挟持片６０，６０の上部を内側へ変位させ、蓄電器５１を強固に圧接可能にしている The upper ends of the sandwiching pieces 60, 60 are bent outward, and a locking groove 62 is formed on the outer periphery of the base of the bent portion 60a.
An annular hooking member 63 such as an O-ring or a rubber band is mounted in the locking groove 62, and the upper portions of the sandwiching pieces 60, 60 are displaced inward by its elasticity, so that the battery 51 can be firmly pressed.

前記挟持片６０，６０の基部の間にテーパ面６４とビス孔６５が形成され、また基板ホルダ７の他側周面に一対の係止突起６６が突設され、該係止突起６６，６６の間に前記シャ−シ５が収容されている。
そして、前記ビス孔６５にビス６８を挿入し、これをシャ−シ５に形成したビス孔６７にねじ込み、基板ホルダ７をシャ−シ５に固定している。 A tapered surface 64 and a screw hole 65 are formed between the base portions of the sandwiching pieces 60, 60, and a pair of locking projections 66 project from the other peripheral surface of the substrate holder 7. The chassis 5 is accommodated between the two.
A screw 68 is inserted into the screw hole 65 and screwed into a screw hole 67 formed in the chassis 5 to fix the substrate holder 7 to the chassis 5.

前記蓄電器５１は実施形態の場合、充放電可能な複数の蓄電池からなり、その外径は基板ホルダ７の高さの約１／２で、その長さは基板８の長さの約１／２に形成され、充電には２４時間を要し、該充電によってＬＥＤ９群を１時間点灯可能にしている。 In the embodiment, the battery 51 is composed of a plurality of chargeable / dischargeable storage batteries, the outer diameter of which is about ½ of the height of the substrate holder 7, and the length thereof is about ½ of the length of the substrate 8. The charging takes 24 hours, and the LED 9 group can be lit for 1 hour by the charging.

このように構成した工事用の照明器具３は、照明器具２と略同径かつ同長の直管状に形成され、これは乳白色の円管状の拡散チュ−ブ４と、該チュ−ブ４の内部に配置したシャ−シ５と、該シャ−シ５の一端部に配置した非常用電源ユニット６と、シャ−シ５の大半部に間隔を置いて配置した複数の基板ホルダ７と、該基板ホルダ７上に装着した基板８と、該基板８の表面に実装した光源である複数のＬＥＤ９と、充放電可能な蓄電器５１と、を備えている。 The construction lighting fixture 3 constructed in this way is formed in a straight tube having the same diameter and the same length as the lighting fixture 2, which is a milky white circular diffusion tube 4, and the tube 4.

前記ＬＥＤ９は、従来の光源として使用されていた蛍光灯と比べると、明るさを同等にした場合、消費電力は蛍光灯の１／２で、寿命は蛍光灯の約５倍になり、蓄電器５１の充放電能力の小能力化ないし小形軽量化を図れる。
したがって、非常用電源ユニット６の小能力化ないし小形軽量化と、蓄電器５１を支持するシャ−シ５の小形軽量化を図れ、またこれらを収納する拡散チュ−ブ４の小形軽量化と、この種の工事用照明器具の小形軽量化を図れる。 Compared with a fluorescent lamp used as a conventional light source, the LED 9 has a power consumption that is ½ that of a fluorescent lamp and a lifetime that is approximately five times that of a fluorescent lamp. The charging / discharging capacity of the battery can be reduced and the size and weight can be reduced.

It is possible to reduce the size and weight of various types of construction lighting fixtures.

また、基板ホルダ７を介して蓄電器５１を基板８の直下に収容し、これらをコンパクトに配置したから、蓄電器５１と光源を平面的に配置したり、蓄電器５１を別個に収納する場合に比べ、シャ−シ５を短くして拡散チュ−ブ４の短小かつ小径化を図れ、この種工事用照明器具の体裁を向上し得る。 In addition, since the capacitor 51 is stored directly under the substrate 8 via the substrate holder 7 and these are arranged compactly, compared to the case where the capacitor 51 and the light source are arranged in a plane, or the capacitor 51 is stored separately, The chassis 5 can be shortened to make the diffusion tube 4 shorter and smaller in diameter, and the appearance of this kind of lighting fixture can be improved.

しかも、基板ホルダ７は内側にインナ−ホルダ５９を一体成形し、基板８の取付けと蓄電器５１の取付けを単一部品で行なっているから、部品点数が低減し構成が簡潔になるとともに、複数の部品を組み付ける場合に比べ、簡便かつ合理的に製作できる。 Moreover, since the inner holder 59 is integrally formed inside the substrate holder 7 and the substrate 8 and the capacitor 51 are attached as a single component, the number of components is reduced, the configuration is simplified, and a plurality of components are provided. Compared to the assembly of parts, it can be manufactured easily and rationally.

次に、前記構成部品を組み付ける場合は、シャ−シ５を所定長さに切断し、その両端部と中間部の所定位置に複数のビス孔を形成し、その両端部に端板１０，１１の屈曲片１４，１５を重合し、これらにビス１６，１７をねじ込んで固定する。

このようにすると、掛止部材５８の弾性によって張出部５５，５５が内側に変位し、切欠溝５６，５６による挟持力が強化されて、基板８を強固に保持する。
この後、前記端板１０寄りのシャ−シ５上に非常用電源ユニット６を収容し、その両側の脚片にビスを挿入し、これをシャ−シ５のビス孔にねじ込んで、前記電源ユニット６を固定する。 After mounting the substrate 8, an annular latching member 58 is latched in the latching grooves 57, 57 at the upper end of the substrate holder 7. This situation is as shown in FIGS.

そして、電源コード４７の一端をキャップ２０の内側に導入し、これを端板１０の透孔２７に挿入し、そのリ−ド線３０の一つを非常用電源ユニット６に接続し、他のリ−ド線３０をシャ−シ５上にアースし、残りのリ−ド線３０を保護チュ−ブ３４に挿入する。
また、蓄電器５１から引き出したリ−ド線３６を、連結したブロックピ−ス５３ａ，５３ｂに接続し、その一方のリ−ド線３６を非常用電源ユニット６に接続し、他方のリ−ド線３６を保護チュ−ブ３５に挿入する。 Then, one end of the power cord 47 is introduced into the inside of the cap 20, and this is inserted into the through hole 27 of the end plate 10, and one of the lead wires 30 is connected to the emergency power supply unit 6, and the other The lead wire 30 is grounded on the chassis 5, and the remaining lead wire 30 is inserted into the protective tube 34.
Also, the lead wire 36 drawn out from the battery 51 is connected to the connected block pieces 53a and 53b, one of the lead wires 36 is connected to the emergency power supply unit 6, and the other lead wire is connected. 36 is inserted into the protective tube 35.

更に、基板８に導通するリ−ド線３６を、連結したブロックピ−ス５２ａ，５２ｂに接続し、その一対のリ−ド線３６を非常用電源ユニット６に接続し、該電源ユニット６の両端から別々に引き出したリ−ド線３６，３６を保護チュ−ブ３４，３５に挿入する。
そして、前記リ−ド線３０，３６を挿入した保護チュ−ブ３４を端板１０の切欠溝３２に挿入し、リ−ド線３６，３６を挿入した保護チュ−ブ３５を端板１０の切欠溝３３に挿入し、それらのリ−ド線３０，３６を端板１０の外側に引き出し、これらをスイッチ４９の接点に接続する。この状況は図６および図１０のようである。 Furthermore, the lead wire 36 that is electrically connected to the substrate 8 is connected to the connected block pieces 52a and 52b, the pair of lead wires 36 are connected to the emergency power supply unit 6, and both ends of the power supply unit 6 are connected. The lead wires 36 and 36 drawn out separately from each other are inserted into the protective tubes 34 and 35.
The protective tube 34 into which the lead wires 30 and 36 are inserted is inserted into the notch groove 32 of the end plate 10, and the protective tube 35 into which the lead wires 36 and 36 are inserted is connected to the end plate 10. The lead wires 30 and 36 are inserted into the notch groove 33 and pulled out to the outside of the end plate 10, and these are connected to the contacts of the switch 49. This situation is as shown in FIGS.

この場合、前記リ−ド線は、蓄電器５１の図３上左端から引き出され、これが基板ホルダ７の内側から非常用電源ユニット６上に配線され、また基板８のリ−ド線は図３上左端から引き出されて非常用電源ユニット６上に配線され、他のリ−ド線が非常用電源ユニット６上に集中して配線される。 In this case, the lead wire is drawn out from the upper left end of the capacitor 51 in FIG. 3, which is wired from the inside of the substrate holder 7 to the emergency power supply unit 6, and the lead wire of the substrate 8 is in FIG. It is pulled out from the left end and wired on the emergency power supply unit 6, and other lead wires are concentrated and wired on the emergency power supply unit 6.

こうして、前記各リ−ド線３０，３６を配線後、キャップ２０の外側からビス２２を挿入し、これを端板１０のネジ孔１８にねじ込んで、キャップ２０を端板１０に固定する。
そして、キャップ２０の外側からナット４８を軸筒部にねじ込み、電源コ−ド４７の基部を保持し、該コ−ド４７を抜け止めする。 Thus, after the lead wires 30 and 36 are wired, the screw 22 is inserted from the outside of the cap 20 and screwed into the screw hole 18 of the end plate 10 to fix the cap 20 to the end plate 10.
Then, the nut 48 is screwed into the shaft tube portion from the outside of the cap 20 to hold the base portion of the power cord 47 and prevent the cord 47 from coming off.

この後、拡散チュ−ブ４をキャップ２０の反対側からシャ−シ５に沿って差し入れ、該拡散チュ−ブ４の内部にシャ−シ５と、該シャ−シ５上に取付けた基板ホルダ７と、非常電源用ユニット６、および基板ホルダ７に装着した基板８とＬＥＤ９、並びにそれらに配線したリ−ド線を収容する。
この場合、前記リ−ド線は前述のように基板ホルダ７および基板８から外側に突出することなく配線され、また他のリ−ド線が非常用電源ユニット６上に集中して配線されているから、拡散チュ−ブ４を容易かつ円滑に差し込める。 Thereafter, the diffusion tube 4 is inserted along the chassis 5 from the opposite side of the cap 20, and the chassis 5 and the substrate holder attached on the chassis 5 are installed inside the diffusion tube 4. 7, the emergency power unit 6, the board 8 and the LED 9 mounted on the board holder 7, and the lead wires wired to them are accommodated.
In this case, the lead wires are wired without protruding outward from the substrate holder 7 and the substrate 8 as described above, and other lead wires are concentrated on the emergency power supply unit 6 and wired. Therefore, the diffusion tube 4 can be inserted easily and smoothly.

そして、拡散チュ−ブ４の一端を端板１０とキャップ２０の間に差し込み、キャップ２０の内面段部に当接させる。
次に、拡散チュ−ブ４の他端にキャップ２１を嵌合し、該キャップ２１の内面に突設したピン２５を通孔２５に挿入し、それらを位置合わせする。
そして、キャップ２１の外側からビス２３をネジ孔１９にねじ込み、キャップ２１を端板１１に取付け、該キャップ２０，２１の間に拡散チュ−ブ４を挟持する。この状況は図３および図８のようである。 Then, one end of the diffusion tube 4 is inserted between the end plate 10 and the cap 20 and brought into contact with the inner surface step portion of the cap 20.
Next, the cap 21 is fitted to the other end of the diffusion tube 4, the pin 25 projecting from the inner surface of the cap 21 is inserted into the through hole 25, and they are aligned.
Then, the screw 23 is screwed into the screw hole 19 from the outside of the cap 21, the cap 21 is attached to the end plate 11, and the diffusion tube 4 is sandwiched between the caps 20, 21. This situation is as shown in FIGS.

こうして組立てた工事用照明器具は図２，３のようで、実施形態の照明器具３は直径６５ｍｍｍ、取付ブラケット４１，４２間の長さ７９０ｍｍの略直管状に形成され、その表面の大半に乳白色の拡散チュ−ブ４が表出している。
前記照明器具３は、不使用時にスイッチ４９がＯＦＦされ、蓄電器５１からの放電を阻止している。また、両側のキャップ２０，２１の脚４５，４６の内側に、図４，５のように電源コード４７が嵌合され、拡散チュ−ブ４の周面に軸方向に沿って整然と配置されている。したがって、不使用時には照明器具３を容易かつコンパクトに保管し得る。 The construction lighting fixture assembled in this way is as shown in FIGS. 2 and 3. The lighting fixture 3 of the embodiment is formed in a substantially straight tube having a diameter of 65 mm and a length of 790 mm between the mounting brackets 41 and 42, and most of the surface is milky white. The diffusion tube 4 is exposed.
In the luminaire 3, the switch 49 is turned off when not in use, thereby preventing discharge from the battery 51. Further, the power cord 47 is fitted inside the legs 45 and 46 of the caps 20 and 21 on both sides as shown in FIGS. 4 and 5, and is neatly arranged along the axial direction on the peripheral surface of the diffusion tube 4. Yes. Therefore, the lighting fixture 3 can be easily and compactly stored when not in use.

次に、前記照明器具３を、例えばトンネル築造時の工事用照明に使用する場合、多数の照明器具３を用意し、これを通常の多数の照明器具２と一緒にトンネル１の坑内の両側壁１ａに縦列に配置する。
前記照明器具２，３の比率は実施形態の場合、５：１に配置され、多数の照明器具２の間に照明器具３を配置する。この状況は図１のようで、照明器具３の設置には取付けブラケット４１，４２が使用される。 Next, when the lighting fixture 3 is used, for example, for construction lighting at the time of tunnel construction, a large number of lighting fixtures 3 are prepared, and this is used together with a number of normal lighting fixtures 2 on both side walls in the tunnel. 1a is arranged in a column.
In the embodiment, the ratio of the luminaires 2 and 3 is 5: 1, and the luminaire 3 is arranged between a large number of luminaires 2. This situation is as shown in FIG. 1, and the mounting brackets 41 and 42 are used for installing the lighting fixture 3.

前記照明器具２，３は商用電源（交流電源）に接続され、その使用時は双方共に給電されて照明器具２，３が点灯し、坑内を照射する。
この場合、前記照明器具３のＬＥＤ９による照射光は、乳白色の拡散チュ−ブ４によって輝度を抑制されるから、目に優しい照射光が得られる。
その際、照明器具３は使用時にスイッチ４９がＯＮされ、商用電源である交流電力が非常用電源ユニット６に入力され、該電源ユニット６のコンバ−タ−機能によって、交流電力が直流電力に変換されて出力される。 The luminaires 2 and 3 are connected to a commercial power source (AC power source). When the luminaires 2 and 3 are used, both are supplied with power, and the luminaires 2 and 3 are lit to irradiate the underground.
In this case, since the luminance of the irradiation light from the LED 9 of the lighting fixture 3 is suppressed by the milky white diffusion tube 4, irradiation light gentle to the eyes can be obtained.
At that time, the switch 49 is turned on when the lighting fixture 3 is used, AC power as a commercial power supply is input to the emergency power supply unit 6, and the AC power is converted into DC power by the converter function of the power supply unit 6. Is output.

前記出力電力は、基板８と蓄電器５１側に分岐し、その一方から基板８に通電され、該基板８に実装された多数のＬＥＤ９を点灯し、他方から蓄電器５１に通電され、該蓄電器５１を充電する。実施形態の蓄電器５１は充電に２４時間を要し、その放電によって１時間点灯する。 The output power branches to the substrate 8 and the capacitor 51 side, and the substrate 8 is energized from one of them, a large number of LEDs 9 mounted on the substrate 8 are lit, and the capacitor 51 is energized from the other, Charge. The battery 51 of the embodiment requires 24 hours for charging, and is lit for 1 hour by the discharge.

このような照明器具２，３の点灯時、商用電源が停電すると、照明器具２が消灯する。一方、蓄電器５１からは直流電力が放電され、非常用電源ユニット６を介して基板９の配線回路に通電され、前記基板９に実装されたＬＥＤ９に給電されて、該ＬＥＤ９が点灯し続ける。
したがって、前記停電時、蓄電器５１による非常用電源によって坑内にＬＥＤ９の照明が得られ、停電時における作業者の安全性が確保される。 When the luminaires 2 and 3 are turned on, if the commercial power supply fails, the luminaire 2 is turned off. On the other hand, from the capacitor 51 DC power is discharged, is energized wiring circuit board 9 via the emergency power unit 6, is powered on LED9 mounted on the substrate 9, the LED9 is that remains lit.
Therefore, at the time of the power failure, the LED 9 is illuminated in the pit by the emergency power supply by the capacitor 51, and the safety of the worker at the time of the power failure is ensured.

前記照明器具３は拡散チュ−ブ４の内部に、非常用電源ユニット６と蓄電器５１、ＬＥＤ９を実装した基板８を収容しているから、照明器具の外部に蓄電器を配置するものに比べて、設置スペ−スがコンパクトになり、体裁が良好になる。
しかも、基板８ないしＬＥＤ９の直下に蓄電器５１を配置し、これらを合理的かつコンパクトに配置しているから、拡散チュ−ブ４の内径を可及的に小径化し、その小形軽量化と体裁の向上を図れる。 Since the luminaire 3 accommodates the emergency power supply unit 6, the capacitor 51, and the substrate 8 on which the LED 9 is mounted inside the diffusion tube 4, the luminaire 3 is compared with the one in which the capacitor is disposed outside the luminaire. The installation space becomes compact and the appearance is good.
In addition, the capacitor 51 is arranged directly under the substrate 8 or the LED 9, and these are rationally and compactly arranged. Therefore, the inner diameter of the diffusion tube 4 is made as small as possible, and the size and weight of the diffusion tube 4 are reduced. Improvements can be made.

そして、基板８ないしＬＥＤ９と蓄電器５１とは十分に離間し、かつこれらが拡散チュ−ブ４に内に十分な空スペ−スを保って配置されているから、ＬＥＤ９の点灯による基板８ないしＬＥＤ９と蓄電器５１の発熱の放熱が促され、それらの機能低下と寿命の低下を防止する。 Since the substrate 8 to the LED 9 and the battery 51 are sufficiently separated from each other and these are disposed in the diffusion tube 4 with a sufficient empty space, the substrate 8 to the LED 9 and the LED 9 are turned on. And heat dissipation of the heat generated by the capacitor 51 is promoted, and their function and life are prevented from being reduced.

一方、前記照明器具３は、蓄電器５１が一対の挟持片６０，６０に保持され、その上端部を掛止部材６３によって掛け止められて、強固かつ確実に保持されているから、トンネル掘削時の振動や衝撃による緩みやガタの発生が防止される。
また、基板８が係合溝５６，５６に係合して挟持され、更に張出部５５，５５の外側の係止溝５７，５７に掛止部材５８が装着されて、張出部５５，５５を内側に変位させ、基板８を強固かつ確実に保持するから、トンネル掘削時の振動や衝撃による緩みやガタの発生を防止し、基板８ないしＬＥＤ９の動作不良を防止し、確実かつ安定した照明が得られる。 On the other hand, in the lighting fixture 3, the capacitor 51 is held by a pair of holding pieces 60, 60, and the upper end thereof is hooked by a hooking member 63, so that it is firmly and securely held. Looseness and backlash due to vibration and shock are prevented.
Further, the board 8 is engaged and held in the engagement grooves 56, 56, and the latching member 58 is attached to the locking grooves 57, 57 outside the overhang portions 55, 55. 55 is displaced inward, and the substrate 8 is firmly and securely held. Therefore, loosening and backlash due to vibration and impact during tunnel excavation are prevented, and malfunctions of the substrate 8 to the LED 9 are prevented. Lighting is obtained.

更に、拡散チュ−ブ４の両端部が端板１０，１１の外周に係合可能に近接して配置されているから、拡散チュ−ブ４が安全かつ確実に保持され、トンネル掘削時の振動や衝撃による緩みやガタの発生を防止される。
また、前記端板１０に二つの切欠溝３２，３３を形成し、これらに保護チュ−ブ３４，３５を押し込み、内部のリード線３０，３６を安全かつ確実に保持するから、断線を防止し配線の安全性を確保する。 Further, since both end portions of the diffusion tube 4 are disposed in close proximity to the outer peripheries of the end plates 10 and 11, the diffusion tube 4 can be held safely and reliably, and vibration during tunnel excavation. Prevents loosening and backlash due to shock.
Further, two notch grooves 32 and 33 are formed in the end plate 10, and protective tubes 34 and 35 are pushed into these to hold the internal lead wires 30 and 36 safely and reliably, thereby preventing disconnection. Ensure wiring safety.

図１１および図１２は本発明の応用形態を示し、前述の構成と対応する構成部分に同一の符号を用いている。
この応用形態は、シャ−シ６９を前述のシャ−シ５よりも側面高さを高く形成し、その中間部の側面に蓄電器５１を出し入れ可能な横長の窓７０を開口している。
